Quantum Twins: Silicon’s Leap in Analog Simulation

Published

on

While quantum computers continue to slowly grind towards usefulness, some are pursuing a different approach—analog quantum simulation. This path doesn’t offer complete control of single bits of quantum information, known as qubits—it is not a universal quantum computer. Instead, quantum simulators directly mimic complex, difficult-to-access things, like individual molecules, chemical reactions, or novel materials. What analog quantum simulation lacks in flexibility, it makes up for in feasibility: quantum simulators are ready now.

“Instead of using qubits, as you would typically in a quantum computer, we just directly encode the problem into the geometry and structure of the array itself,” says Sam Gorman, quantum systems engineering lead at Sydney-based start-up Silicon Quantum Computing.

Yesterday, Silicon Quantum Computing unveiled its Quantum Twins product, a silicon quantum simulator, which is now available to customers through direct contract. Simultaneously, the team demonstrated that their device, made up of fifteen thousand quantum dots, can simulate an often-studied transition of a material from an insulator to a metal, and all the states between. They published their work this week in the journal Nature.

“We can do things now that we think nobody else in the world can do,” Gorman says.

The powerful process

Though the product announcement came yesterday, the team at Silicon Quantum Computing established its Precision Atom Qubit Manufacturing process following the startup’s establishment in 2017, building on the academic work that the company’s founder, Michelle Simmons, led for over 25 years. The underlying technology is a manufacturing process for placing single phosphorus atoms in silicon with sub-nanometer precision.

“We have a 38-stage process,” Simmons says, for patterning phosphorus atoms into silicon. The process starts with a silicon substrate, which gets coated with a layer of hydrogen. Then, using a scanning-tunneling microscope, individual hydrogen atoms are knocked off the surface, exposing the silicon underneath. The surface is then dosed with phosphine gas, which adsorbs to the surface only in places where the silicon is exposed. With the help of a low temperature thermal anneal, the phosphorus atom is then incorporated into the silicon crystal. Then, layers of silicon are grown on top.

“It’s done in ultra-high vacuum. So it’s a very pure, very clean system,” Simmons says. “It’s a fully monolithic chip that we make with that sub-nanometer precision. In 2014, we figured out how to make markers in the chip so that we can then come back and find where we put the atoms within the device to make contacts. Those contacts are then made at the same length scale as the atoms and dots.”

Though the team is able to place single atoms of phosphorus, they use clusters of ten to fifty such atoms to make up a so-called register for these application-specific chips. These registers act like quantum dots, preserving quantum properties of the individual atoms. The registers are controlled by a gate voltage from contacts placed atop the chip, and interactions between registers can be tuned by precisely controlling the distances between them.

While the company is also pursuing more traditional quantum computing using this technology, they realized they already had the capacity to do useful simulations in the analog domain by putting thousands of registers on a single chip and measuring global properties, without controlling individual qubits.

“The thing that’s quite unique is we can do that very quickly,” Simmons says. “We put 250,000 of these registers [on a chip] in eight hours, and we can turn a chip design around in a week.”

What to simulate

Back in 2022, the team at Silicon Quantum Computing used a previous version of this same technology to simulate a molecule of polyacetylene. The chemical is made up of carbon atoms with alternating single and double bonds, and, crucially, its conductivity changes drastically depending on whether the chain is cut on a single or double bond. In order to accurately simulate single and double carbon bonds, the team had to control the distances of their registers to sub-nanometer precision. By tuning the gate voltages of each quantum dot, the researchers reproduced the jump in conductivity.

Now, they’ve demonstrated the quantum twin technology on a much larger problem—the metal-insulator transition of a two-dimensional material. Where the polyacetylene molecule required ten registers, the new model used 15,000. The metal-insulator model is important because, in most cases, it cannot be simulated on a classical computer. At the extremes—in the fully metal or fully insulating phase—the physics can be simplified and made accessible to classical computing. But in the murky intermediate regime, the full quantum complexity of each electron plays a role, and the problem is classically intractable. “That is the part which is challenging for classical computing. But we can actually put our system into this regime quite easily,” Gorman says.

The metal-insulator model was a proof of concept. Now, Gorman says, the team can design a quantum twin for almost any two-dimensional problem.

“Now that we’ve demonstrated that the device is behaving as we predict, we’re looking at high-impact issues or outstanding problems,” says Gorman. The team plans to investigate things like unconventional superconductivity, the origins of magnetism, and materials interfaces such as those that occur in batteries.

Although the initial applications will most likely be in the scientific domain, Simmons is hopeful that Quantum Twins will eventually be useful for industrial applications such as drug discovery. “If you look at different drugs, they’re actually very similar to polyacetylene. They’re carbon chains, and they have functional groups. So, understanding how to map it [onto our simulator] is a unique challenge. But that’s definitely an area we’re going to focus on,” she says. “We’re excited at the potential possibilities.”

The Nintendo Switch 2 proved me wrong in several ways, and it’s why I’d suggest buying it now before price hikes

Published

on

I’ve been critical of the Nintendo Switch 2 in previous stories, given the price of its games and, to a lesser extent, the handheld’s price itself, but after giving it a shot, it’s a strong recommendation. You can now grab the Nintendo Switch 2 bundle on Best Buy for $629.95 (was $684.95).

The bundle includes Mario Kart World and Donkey Kong Bananza, two exclusive Switch 2 titles that showcase the fun ready to be had with the console this President’s Day. I’ve bought and played both games (not for $80), and I can say that they serve as perfect introductions to the Switch ecosystem, especially if you’ve not played many Nintendo games.

potential price increase. Multiple reports suggest the threat is from a combination of tariffs and the ongoing RAM crisis.

Since Valve is also hesitant to announce prices for the Steam Machine’s launch due to the high cost of memory, Nintendo will likely announce a price increase for its Switch 2 soon.

That makes now the best time to make a move if you’ve been considering a Switch 2 – and I can attest to it being worth every cent, especially since its life cycle has only just begun. Expect to see several exclusives launch later down the line, and The Duskbloods is already one that’s caught my eye.

DIY Macropad Rocks A Haptic Feedback Wheel

Published

on

Macropads can be as simple as a few buttons hooked up to a microcontroller to do the USB HID dance and talk to a PC. However, you can go a lot further, too. [CNCDan] demonstrates this well with his sleek macropad build, which throws haptic feedback into the mix.

The build features six programmable macro buttons, which are situated either on side of a 128×64 OLED display. This setup allows the OLED screen to show icons that explain the functionality of each button. There’s also a nice large rotary knob, surrounded by 20 addressable WS2811 LEDs for visual feedback. Underneath the knob lives an an encoder, as well as a brushless motor typically used in gimbal builds, which is driven by a TMC6300 motor driver board. Everything is laced up to a Waveshare RP2040 Plus devboard which runs the show. It’s responsible for controlling the motors, reading the knob and switches, and speaking USB to the PC that it’s plugged into.

It’s a compact device that nonetheless should prove to be a good productivity booster on the bench. We’ve featured [CNCDan’s] work before, too, such as this nifty DIY VR headset.

Anthropic’s Powerful Claude Opus AI Model Is Getting an Upgrade

Published

on

Anthropic’s most powerful Claude model is leveling up, with the company saying in a blog post Thursday that Claude Opus 4.6 will be even better at coding and creating projects on the first go.

Claude Opus 4.5 is already a powerful coding model, with its release in November setting up Claude Code’s viral vibe-coding moment over the holidays. Claude’s proven coding prowess and new Cowork feature have Wall Street anxious, with many tech stocks falling in recent weeks, over concerns that people won’t need software products in the future.

Anthropic said the new model is more focused on solving the biggest challenges, like the inner workings of complex apps, while also handling the easy steps more quickly. As a reasoning model, Opus 4.6 works by breaking down the steps it needs to take to do what you ask it to and putting together a plan before starting on it. It’ll also go back and check its work on those steps, sometimes making multiple attempts without you asking for it.

Sometimes the model can spend too much effort on a task, which Anthropic said can be resolved by reducing its effort level from the default “high” setting.

The Claude Opus models are available for paying Claude users on the Pro, Max, Team and Enterprise plans. The cheapest of those, Pro, costs $20 a month (or $17 a month if you pay annually). The Pro plan comes with usage limits for Opus, which users can hit after a few hours of vibe coding and then have to wait several hours for it to reset.

Aside from Opus, Anthropic has smaller, less powerful models in Sonnet 4.5 and Haiku 4.5.

One of Europe’s largest universities knocked offline for days after cyberattack

Published

on

The computer systems of La Sapienza in Rome, one of the largest universities in Europe with around 120,000 students, have been down for three days following an apparent ransomware attack. 

In a post and stories on Instagram published Tuesday, the university said that it took down its systems out of precaution following the cyberattack, that it was investigating the incident and working on restoring all digital services, and that some communication channels such as email and workstations are “partially limited.” 

The school also said that it was working to restore systems based on backups, which were not affected by the hack. 

As of this writing the Sapienza website remains down.

Italian daily news outlet Il Corriere della Sera reported this week that the disruption is due to a ransomware attack, something that the school nor other authorities have confirmed so far. The hackers allegedly sent the university a link to a request for a ransom, which has a countdown of 72 hours, which would start only once the link is clicked.

Do you have more information about this attack, or the Femwar02 ransomware gang? From a non-work device, you can contact Lorenzo Franceschi-Bicchierai securely on Signal at +1 917 257 1382, or via Telegram, Keybase and Wire @lorenzofb, or email.

La Sapieza did not respond to TechCrunch’s request for comment sent via email. It’s unclear if the university is able to accept email at the time we reached out.

Spokespeople for Italy’s national cybersecurity agency, Agenzia per la Cybersicurezza Nazionale (or ACN), which is investigating the incident, did not immediately respond to a request for comment, asking for more information and if the attack was caused by ransomware.

In another article on Wednesday, Il Corriere reported that the hacking group behind the attack is called “Femwar02,” which was previously unknown prior to this incident. The gang used the BabLock malware, which was discovered in 2023 and is also known as Rorschach, according to the report.

La Sapienza said that exams are proceeding as normal, but students who want to sign up for exams must do so directly with professors. The school also set up “infopoints” on several locations on campus to provide information to students. 

Like other types of organizations, universities and schools are frequent targets of hackers. Last year, the notorious hacking group ShinyHunters hacked Harvard University and University of Pennsylvania and stole data — without using malware to encrypt its systems — in an effort to extort the schools. The hackers revealed this week that the schools did not pay the ransom.

AstellKern’s doubles down on luxury with its SP4000 music player

Published

on

Astell&Kern is doubling down on the high-end with the launch of its most premium portable music player yet. It also comes with a suitably luxurious way to store it.

The company has unveiled the A&ultima SP4000 Copper, a limited-edition flagship digital audio player. It is launching the SP4000 alongside the Collector’s Atelier, a leather valet designed for serious head-fi collectors.

The headline act here is the SP4000 Copper. It’s based on Astell&Kern’s existing SP4000 platform but rebuilt using 99.98% pure copper. This is a material prized for its audio properties and notoriously difficult to work with.

According to Astell&Kern, the player requires a multi-layer stabilisation process and extremely precise machining to ensure long-term durability. All this is in the name of cleaner signal transfer and better shielding.

Under the hood, it keeps the same class-leading internals as the standard SP4000, including a quad-DAC setup and octa-circuit architecture. However, Astell&Kern says the copper chassis directly shapes the sound with the result described as deeper, more authoritative bass, a richer midrange, and treble that decays more naturally. The device is tuned for listeners who want recordings to sound as close to the original performance as possible.

As you’d expect, exclusivity comes at a price. The A&ultima SP4000 Copper is a limited edition and is available now with a suggested retail price of £3999 / $4499 / €4699.

Alongside it, Astell&Kern has introduced the Collector’s Atelier, a premium leather valet designed to house a player, earphones and accessories. It’s made using Perlinger leather, sourced from a German tannery that’s been operating since 1864.

The leather undergoes a specialised shrinking process that preserves its natural grain while improving durability. This means it should age gracefully with use rather than looking worn out. The Collector’s Atelier is available now for £229 / $260.

Rounding out the launch are two previously announced products that are now officially on sale. The AK HC5, a compact USB DAC priced at £399, targets portable listening setups. Meanwhile, STELLA, a reference-grade earphone developed with Volk Audio and Grammy-winning mastering engineer Michael Graves, sits at the very top of Astell&Kern’s in-ear lineup.

Taken together, it’s a clear statement of intent from Astell&Kern. This isn’t about mass appeal — it’s about pushing materials, sound quality and craftsmanship as far as possible for listeners who want the absolute best, even on the move.

The perfect soundbars for small spaces

Published

on

Not everyone has the space for a surround sound system or even a full-sized soundbar. If that’s your situation, we’ve come up with several small options that will work for your crowded space.

We’ve tried to ensure with this list of the best small soundbars that even though they’re small, there’s still an option that will suit every need.

We’ve chosen Dolby Atmos soundbars, soundbars that work with older TVs that don’t have HDMI ports, or models that come with subwoofers. We’ve got an array of options to choose from.

Any soundbar we look at, we do so by watching lots of movies and listening to plenty of music. We examine how well each model handles dialogue, effects, and different genres of music. From these tests, we determine which ones are worth your cash.

Keep reading to discover all the best small soundbars available right now. We have other guides to have a look too which includes our best soundbars and the best Dolby Atmos soundbars.

We’ve also narrowed down the best surround sound systems for those with the space and budget to create a bigger sound system.

Learn more about how we test soundbars

Soundbars were created to boost TV sound quality – which means we end up watching a lot of TV. We play everything – news reports for voices, movies for scale and effects steering – to ensure that the soundbars that come through the doors at Trusted Reviews are given a proper challenge. We’ll play different genres of music, too, since a good soundbar should be capable of doubling-up as a great music system.

More complex soundbars feature network functionality for hooking up to other speakers and playing music around the home, so we test for connectivity issues and ease of use. We cover the spectrum of models available, everything from cheap soundbars costing less than £100 to those over £1000, to ensure our reviews benefit from our extensive market knowledge. Every product is compared to similarly priced rivals, too.

  • Clean and balanced sound

  • Upgradeable

  • Excellent size

  • Amazon Alexa and Google Assistant support

  • HDMI eARC input only

  • Limited DTS support

Compared to the original Beam, the Beam Gen 2  comes with addition of an eARC HDMI port that allows it to play full-fat lossless Atmos soundtracks.

That also means you’ll need an eARC compatible TV to get the best out of it.

Otherwise, things remain the same with the Beam 2nd Gen, with it best suited for TVs up to and including 49-inches.

Advertisement

The current Beam supports Wi-Fi and the Sonos S2 app, which offers access to a multitude of streaming services such as Tidal, Deezer and Qobuz, as well as Sonos’ own Radio service.

You can also call on voice assistance in Google Assistant and Amazon Alexa, as well as initiate Trueplay (as long as you’ve got an iOS device), which optimises the Beam’s audio performance according to the environment it is in.

During testing we found it produced an excellent audio performance, offering a solid low end and a generally balanced sound across the frequency range.

It also handled music impressively, with no noticeable distortion, handling more subtle elements with nuance. The addition of Dolby Atmos isn’t achieved through upfiring speakers but through virtual processing, and it offers a good performance with a decent sense of dimensionality when we watched Captain Marvel on Disney+.

The Beam 2 doesn’t have fully-featured DTS support but the similarly compact Polk Magnifi Mini AX and Denon Home Sound bar 550 do support DTS:X.

Like the Sonos both can be paired with a subwoofer for added ‘oomph’. A slightly more expensive but still impressive alternative is the Sennheiser Ambeo Mini.

While the Beam 2 is not perfect, as a means of getting Atmos into the home in a small form factor, the Sonos Beam Gen 2 is a very good way of doing so.

  • Sharp, clear and spacious sound

  • Small footprint

  • Affordable at its current price

  • Wall-mount brackets included

  • LED menu is practically invisible from a seated position

  • No HDMI eARC

The Samsung HW-S61B is still going and serves as an excellent, affordable rival to the Sonos Beam Gen 2.

Its a compact speaker cabale of producing a crisp, clear and punchy sound. It offers plenty of energy and outright attack that easily betters anything a TV can produce.

Its built-in subwoofer provides impact to action scenes, and with Atmos content, the soundstage is bigger than the dimensions of the bar and TV, producing plenty of size and scale to go with Hollywood blockbusters.

Advertisement

It’s pretty solid performer with music content whether over Wi-Fi or Bluetooth, though the former produces a clearer, more detailed performance. The lack of HDMI eARC is a disappointment as it means you won’t be getting the highest quality Dolby Atmos sound possible, and we’re not big fans of the design when it comes to placement of the LED screen. We can barely see it at the best of times given how small it is.

Features include Amazon Alexa voice control, though this would need another connected speaker to be able to use. AirPlay 2 is another means of playing audio to the system, while if you have a Samsung Galaxy smartphone, you can tap it on the surface of the soundbar and play music to it.

If after you’ve bought the speaker, you’re looking to upgrade and add more, the S61B does support the SWA-9200S wireless rear speaker system.

If you have a Samsung Q-Symphony compatible TV can also take advantage of that feature, whereby the TV and soundbar speakers combine for a bigger sound.

Advertisement

There are other options in the market if you are looking for a soundbar and subwoofer combo, most notably the Polk MagniFi Mini AX, but its Atmos performance isn’t as convincing as the Samsung.

New models have launched this one first went on sale, and we’ll be hoping to get reviews of those models at some point.

  • Clean and powerful TV audio

  • Surprising amount of bass

  • Wide soundstage

  • Optional surround sound

  • Remote setup can be fiddly

  • Better at TV than music

If you’re something with an older TV (say a Pioneer Kuro) or have a second, smaller TV without HDMI inputs, the Sonos Ray is tailor made for you.

It only supports audio through an optical connection, so you won’t have to worry about HDMI handshake issues.

Audio through an optical connection keeps things simple enough, though you do miss out on advanced 3D audio like Dolby Atmos and DTS:X. There’s only enough bandwidth for Dolby Digital and DTS soundtracks.

There’s no built-in microphones for voice control from the likes of as Amazon Alexa and Google Assistant. You can still have those smart features, but you’ll need to connect the Ray to another smart speaker.

Advertisement

The design looks a little different from other Sonos soundbars with its lozenge-shaped look and curved ends. Our reviewer felt it was a less in-your-face design that makes the Ray better to blend in with its surroundings more. You can also fit it into an AV rack if you wanted to conceal it from view.

The sound is surprisingly wide for its size, with effective bass performance too. It offers a clear and obvious improvement on a TV with dialogue making audio tracks much easier to understand. With music we felt it sounded decent, perhaps not quite as good as it is with TV series and films, but passable enough. For its primary job of making audio clearer, the Sonos Ray does a brilliant job.

  • Exciting, dynamic sound (in the right mode)

  • Ultra-compact dimensions

  • Comes with a subwoofer

  • Good range of connections

  • Sub can hog the attention at times

  • Not truly immersive

While a small soundbar is helpful in terms of reducing space, its size isn’t always great for producing a more cinematic sound, especially when it comes to bass. The Polk MagniFi Mini AX has you covered in that respect.

This an ultra-compact Dolby Atmos/DTS:X soundbar from American brand Polk, and it differs from other options on this list in that it is not just an all-in-one effort but one that comes with sizeable subwoofer.

This allows it produce and energetic and dynamic performance, and given the weight and power behind the subwoofer’s performance, it’s probably one that’s sure to alert the neighbours to what you’re watching.

In our opinion the Polk doesn’t full suffice as an immersive soundbar but performs better than the Creative Stage 360. It can do a decent impression of height effects but not with the greatest sense of definition, while its soundstage is front heavy, though you can add Polk’s SR2 surround speakers as real channels for a greater sense of space.

Advertisement

Dialogue can be enhanced with Polk’s VoiceAdjust technology, although we found that while it did its job of boosting voices, it also had a tendency to raise surrounding noise as well.

Tonally we felt the soundbar sounded accurate and there’s good levels of detail and clarity to enjoy when the soundbar is put into its 3D mode, which also gives a bigger, wider soundstage to Atmos and DTS:X soundtracks.

With music it’s a solid performer, playing music with a crispness that we found avoided sibilance or harshness.

With Chromecast available along with Bluetooth, AirPlay 2, Spotify Connect and a USB connection that can play MP3 music. With Atmos and DTS:X support for the same price as the Sonos Sub Mini, this is a good value soundbar/subwoofer combination.

  • Impressive nearfield Dolby Atmos effect

  • Clear, articulate voices

  • Solid feature set

  • Versatile footprint

  • Classy design

  • Short on meaningful bass

  • Fussy indicator light arrangement

Measuring in at 52 x 72 x 110cm (WHD) and weighing under 2kg, the SB700 is stocky yet lightweight enough to carry from room to room, which means it can double as both a sonic enhancer for small TVs and a companion for a workstation. We would advise against relying on the SB700 as the main audio source for a living room, though.

Included with the SB700 is a useful remote control that sports treble and bass controls, input selection and all the various EQ modes including voice, movie, music, night and neutral. Sharp also usefully throws in an HDMI cable, which plugs easily into the soundbar’s rear and shares a port alongside optical, USB (service) and 3.5-mm audio inputs.

Powering the four onboard 1.75-inch drivers is a Class D-based 140W of peak power. Plus, as well as Dolby Atmos decoding, the Sharp processes a 3D mode, also known as DAP (Dolby Atmos Processing). We especially appreciate how the SB700 is a plug-and-play device and supports Bluetooth 5.3 connectivity too.

Overall we were impressed with the SB700’s audio quality. While it does struggle with bass and doesn’t quite offer a satisfying loud movie night, it still offers plenty of prowess with midrange and high frequencies too. Plus dialogue sounds clear too.

Advertisement

  • Clear, detailed sound with decent bass

  • Decent with music

  • Neat and tidy design

  • Impressive SuperWide feature

  • Odd volume issues with sources

What the Creative Stage Pro lacks in features, it more than makes up for in terms of sound and design quality.

While the Stage Pro feels more like a desktop soundbar rather than a cinema bar, it does sport a smart appearance with a useful display at its front that can be seen from the sofa. Although undoubtedly compact, its height can block the TV’s IR receiver which means you might struggle to use your remote control with your TV.

Otherwise, the bar is paired with a similarly unassuming subwoofer that relies on a wired connection to the soundbar. Usefully, as it’s front-firing, you’re free to place it anywhere.

As mentioned earlier, despite its “Pro” moniker, there aren’t many features at play here. While there is Bluetooth 5.3 and support for Dolby Audio and Dolby Digital+ soundtracks, there’s no Wi-FI. Even so, it still covers the basic connections including an optical input, DMI ARC, USB-C and even an auxiliary input.

Advertisement

Having said that, there is one notable feature: SuperWide. This expands the size of the Stage Pro’s sound and pushes audio out wide in a way that’s much bigger than the speaker. Depending on how close you’re sitting to the speaker, you can choose between Near-Field and Far-Field too. The latter is especially impressive as it manages to keep voices clear while expanding the width of the soundstage.

Overall, although it’s not an immersive soundbar, we were pretty impressed with the sense of the height it can provide. Otherwise, the subwoofer does a good job at providing a punchy sense of bass.

We did struggle with the soundbar’s volume levels, especially when switching between sources, as the Stage Pro can veer from excessively loud to surprisingly quiet. It’s frustrating, as it seems as if there’s no way to minimise those swings in volume.

FAQs

Does a soundbar have to match your TV size?

No, but it’s best for them to at least be similar in size. For a full-size soundbar, it’s best to partner them with TVs 50-inches and above. With compact soundbars that TVs’ 49-inches and smaller would be the best fit.

Advertisement
Do soundbars have to be the same brand as the TV?

No, you won’t need a soundbar that’s the same brand as the TV. Any soundbar can work with any TV it is connected to. Where you may want to consider is whether the soundbar and TV have been optimised to work best with each other. LG and Sony both have soundbars that share features with their respective TVs.

The Latest Apple Watch Is $100 Off

Published

on

Is it finally time to upgrade that aging Apple Watch that you’re charging twice a day? I have some great news for you! The Apple Watch Series 11 is marked down at major retailers like Amazon and Best Buy to as low as $300 for the base version, or $400 for the upgraded GPS + Cellular version, depending on your finish and included band choice.

While we’ve enjoyed previous generations of Apple Watch, the Series 11 made one of the most major improvements yet to the popular line of smartwatches. With the upgraded battery and extra optimization features, the standard Apple Watch can now last an entire day and then some on a single charge. That’s great news for anyone who wants to get the most out of their watch during the day, and then use it to track their sleep at night.

That improved battery life also lets you take advantage of all the updated health tracking features found on the Apple Watch Series 11. The biggest new feature is monitoring for high blood pressure, which will keep track of your vitals over a two week period before alerting you if it thinks you should see a doctor. While it isn’t an official medical device, it’s cleared by the FDA, and at least gives you some helpful information from information it was already gathering anyway.

Otherwise, it has all the features you’d expect from an Apple Watch, including sleep tracking, fitness features for different sports and activities, and a close connection to your iPhone for messages and notifications. If you opt for the version that includes a cellular connection, it features both satellite and 5G messaging, with helpful tips for getting the best connection right on the watch.

I spotted the marked down GPS-only Apple Watch Series 11 at Amazon and Best Buy, with quite a few color and band options in stock at both retailers. Both Amazon and Best Buy also had the versions that support a cellular connection as well, albeit with fewer options at the discounted price. If you’re curious about all the changes to the latest version, make sure to swing by our full review for a complete hands-on experience.

In Wisconsin, Dual Enrollment Stalls: Teachers Must Go Back to School

Published

on

It’s fourth period in the auto lab at Vel Phillips Memorial High School in Madison, Wisconsin, and a dozen students maneuver between nearly as many cars.

At one bay, a junior adjusts the valves of an oxygen-acetylene torch and holds the flame to a suspended Subaru’s front axle to loosen its rusty bolts. Steps away, two classmates tease each other in Spanish as they finish replacing the brakes on a red Saab. Teacher Miles Tokheim moves calmly through the shop, checking students’ work and offering pointers.

After extensive renovations, the lab reopened last year with more room and tools for young mechanics-in-training. What visitors can’t see is the class recently got an upgrade, too: college credit.

Through dual enrollment, high schoolers who pass the course now earn five credits for free at Madison College and skip the class if they later enroll. Classes like these are increasingly common in Wisconsin and across the country. They’ve allowed more high schoolers to earn college credit, reducing their education costs and giving them a head start on their career goals.

Wisconsin lawmakers and education officials want more high schoolers to have this opportunity. But these classes need teachers with the qualifications of college instructors, and those teachers are in short supply.

That leaves many students — disproportionately, those in less-affluent areas — without classes that make a college education more attainable.

“What’s at stake is access to opportunity, especially for high school students at Title I, lower-income high schools, rural high schools … It’s really been an on-ramp for so many students,” said John Fink, who studies dual enrollment at Columbia University’s Community College Research Center. “But we also know that many students are left behind.”

To teach the auto class, Tokheim had to apply to become a Madison College instructor. As a certified auto service technician with a master’s degree, the veteran teacher met the college’s requirements for the course.

But for many teachers, teaching dual enrollment would require enrolling in graduate school, even if they already have a master’s degree. That, school leaders say, is a hard sell, despite the state offering to reimburse districts for the cost. Teachers in Wisconsin often don’t make much more money teaching advanced courses the way they do in some other states, and adding these courses doesn’t raise a school’s state rating.

“You’re asking people who are well educated to begin with to go back to school, which takes time and effort, and their reward for that is they get to teach a dual-credit class,” said Mark McQuade, Appleton Area School District’s assistant superintendent of assessment, curriculum and instruction.

High Standards, Short Supply

Nationwide, the number of high schoolers earning college credit has skyrocketed in recent years. In Wisconsin, the tally has more than doubled, with students notching experience in subjects ranging from manufacturing to business.

Most earn credit from their local technical college without leaving their high school campus. In the 2023-24 school year, one in three community college students in the state was a high schooler.

Education and state leaders have welcomed the trend, pointing to the potential benefits: Students who take dual-enrollment classes are more likely to enroll in college after high school. Theycan save hundreds or thousands of dollars on college tuition and fees. If they do enroll in college, they spend less time completing a degree.

“It also proves to the kids — to some of our kids that are first-generation — that they can do college work,” McQuade said.

But not all students get these advantages. Many Wisconsin schools offer very few dual-enrollment courses, or none at all. A July Wisconsin Policy Forum analysis showed small, urban or high-poverty schools are least likely to offer the classes.

Wisconsin Watch talked to leaders in five school districts. All said the shortage of qualified teachers was one of the biggest barriers to growing their dual-enrollment programs.

In 2015, the Higher Learning Commission, which oversees and evaluates the state’s technical colleges, released new guidelines about instructor qualifications. The new policy required many of Wisconsin’s dual-enrollment teachers to have a master’s degree and at least 18 graduate credits in the subject they teach, just like college instructors.

In 2023, the commission walked back the new policy.

By then, colleges across the state had already adopted the higher standard.

Meanwhile, Wisconsin high schools have struggled to hire and retain teachers, even without college credit involved. Four in 10 new teachers stop teaching or leave the state within six years, a 2024 Department of Public Instruction analysis shows.

The subject-specific prerequisite is much different from the graduate education K-12 teachers have historically sought: the kind that would help them become principals or administrators, said Eric Conn, Green Bay Area Public Schools’ director of curricular pathways and post-secondary partnerships.

“To advance in education, it wasn’t about getting a master’s in a subject area. It was getting a master’s in education to develop into educational administration or educational technology,” Conn said. For teachers who already have a master’s degree, he said, going back to school just to teach one or two new classes is “a large ask.”

Funding Tempts Few

When the Higher Learning Commission announced the heightened requirements in 2015, leaders of the Wisconsin Technical College System sounded the alarm. They warned that 85 percent of the instructors currently teaching these classes could be disqualified, whittling students’ college credit opportunities.

Wisconsin education leaders called on the Legislature to allocate millions of dollars to help teachers get the training they’d need — and they agreed. In 2017, lawmakers created a grant program to reimburse school districts for teachers’ graduate tuition. But of the $500,000 available every year, hundreds of thousands go unused.

“Nobody’s ever, ever requested this funding and been denied because of a funding shortage,” said Tammie DeVooght Blaney, executive secretary of the Higher Educational Aids Board, which manages the grant.

Tuition and fees for a single graduate credit at a Universities of Wisconsin school can cost over $800, putting the total cost of 18 graduate credits at around $15,000. For teachers who don’t already have a master’s degree, the cost is even steeper. The state grant requires teachers or districts to front the cost and apply for reimbursement yearly, with no guarantee they’ll get it.

A handful of Green Bay teachers have used the grant, Conn said, but many just aren’t interested in returning to school, even if it’s free.

The district offers 50 dual-enrollment courses, but he’d like to offer classes in more core subjects, which help students meet general college education requirements. There just aren’t enough teachers qualified to teach college sciences and math to offer the same options across the district’s four high schools.

Teachers are busy, and not just in the classroom, said Jon Shelton, president of AFT-Wisconsin, one of the state’s teachers unions. Many already spend extra hours coaching, grading or leading after-school activities. Those who do go back to school typically enroll in one class at a time, he said, meaning they could be studying for several years.

Pros and Cons

The financial perks for teachers returning to school for dual-enrollment credentials are dubious at best.

Some teachers get a salary bump for obtaining a master’s degree, and some earn modest bonuses for teaching dual enrollment. But many teachers make no more than they would have without the extra training.

“There’s no incentive,” said Tokheim, the Madison auto instructor, who receives a $50 yearly stipend for teaching the college course. In contrast to his standard classes, his dual-enrollment class required him to attend two kinds of training.

There’s little incentive for schools either. They receive no extra state funding to offer college-level courses. Plus, the classes don’t factor into their state report card score, which measures students’ standardized test performance and graduation preparation, among other things.

Leaders at Central High School in Sheboygan wish it did. At that school, where the majority of students are Latino and almost all are low-income, one in three students took dual-enrollment courses in the 2023-24 school year. Still, the state gave the school a failing grade.

“It’s an afterthought in our report card, and it’s always the thing that we can celebrate,” Principal Joshua Kestell said.

So why would a teacher take on the added schooling?

“It’s good for kids,” Tokheim said. “That’s why they get us teachers, because we care too much.”

Other potential draws: the challenge of teaching more rigorous courses and the opportunity to collaborate with college instructors.

Heather Fellner-Spetz retired two years ago from teaching English at Sevastopol High School in Sturgeon Bay. She taught college-level oral communication classes for 10 years before she retired. When the Higher Learning Commission set the heightened requirements, she was allowed to continue teaching dual enrollment while she studied for more graduate credits.

“There wasn’t much I didn’t enjoy about teaching it. It was just fabulous,” Fellner-Spetz said.

She especially liked having a college professor observe her class, and she said it was good for the students, too. “When they had other people come into the room and watch the lesson or watch them perform, it just ups the ante on pressure.”

Meanwhile, the jury is still out on whether it’s necessary for dual-enrollment teachers to have the same credentials as college professors.

“Folks running these programs generally would say that teaching a quality college course to a high school student requires a unique skill set that blends high school and college teaching, and that is not necessarily captured by the traditional (graduate coursework) standard,” Fink said.

Wisconsin educators are divided on that question. Fox Valley Technical College has kept the higher standard, limiting the number of Appleton teachers who qualify. McQuade, the Appleton leader, questions those “restrictions,” saying he believes his teachers are well qualified to teach college-level courses. A different standard tied to student performance, for example, could let his district offer more classes across each of its schools.

Schauna Rasmussen, dean of early college and workforce strategy at Madison College, said the answer isn’t to lower the standard, but to help more teachers reach it.

In October, a group of Republican Wisconsin lawmakers introduced a bill aimed at making it easier for students to find dual-enrollment opportunities. It would create a portal for families to view options and streamline application deadlines, among other changes.

It doesn’t address the shortage of qualified teachers.

“Separate legislation would likely have to be introduced addressing expanding the pool of teachers for those programs,” Chris Gonzalez, communications director for lead author State Sen. Rachael Cabral-Guevara, wrote in an email.

So far, no such legislation has been introduced.
