Alberto Carvalho resigned as Los Angeles Unified's superintendent this week, four months after the FBI raided his office over a collapsed six-million-dollar AI chatbot contract, the same week a Stanford study found that AI writing tools change their feedback once a student's race or gender shows up in the prompt. Utah's bell-to-bell phone ban takes effect statewide in eight days, and the summer science program that just enrolled its largest class in 67 years is betting AI belongs in the lab as a research tool, not a shortcut.

Science
The Largest Science Class in 67 Years Just Enrolled. Its Director Has a Theory About Where AI Actually Belongs.

Summer Science Program International enrolled 720 high school students this year, the largest class in the nonprofit's 67-year history, spread across 13 college campuses including Colby College in Maine, Albion College in Michigan, and the University of Guelph in Ontario, according to K-12 Dive. Students spend several weeks on topics ranging from astrophysics to bacterial genomics to cell biology, working in small teams rather than competing against each other. Between 65% and 80% of past participants go on to pursue STEM fields in college, according to the program.

Amy Kim, the program's chief program officer, told K-12 Dive the model deliberately avoids a competition format: students get the tools they need and are expected to experience failure along the way. Kim also pointed to a legitimate use for AI in science instruction, citing diagnostic medical literature review as an example, since no single physician can track millions of published case studies. That distinction, between AI as a research tool scientists actually need and AI as a shortcut around the thinking a science class is supposed to teach, is worth bringing into your own classroom before the fall.

Try This — Ready to Use
When you introduce AI tools in a science unit this fall, frame the question the way Amy Kim does: what task is too large for a single person to do well, not what task is too tedious for a student to do themselves. A literature review across thousands of papers fits the first category. A lab report a student could write unaided does not.
Try This in Any Class — Today
Before the end of class, ask each student to name one thing they are still unsure about, not what they understood. Collect the responses anonymously on an index card or a shared document. The list of confusions is a more accurate read on where tomorrow's lesson needs to start than any homework completion rate.

Carvalho Resigned From LAUSD. The FBI Investigation Into His AI Chatbot Deal Didn't.
The Development

Alberto Carvalho resigned as superintendent of Los Angeles Unified, the nation's second-largest school district, effective June 21, according to NBC News and CNN. The resignation comes four months after the FBI raided his office, his San Pedro home, and a property near Miami on February 25, in an investigation district officials have linked to LAUSD's contract with AllHere, a now-defunct vendor that built an AI chatbot called "Ed" for the district. LAUSD signed a $6 million contract with AllHere two years ago and had paid the company $3 million before the deal collapsed. AllHere's founder, Joanna Smith-Griffin, was separately arrested and charged with securities fraud, wire fraud, and identity theft. Carvalho has not been charged with a crime and is not named in the case against Smith-Griffin; Acting Superintendent Andrés Chait remains in the role until the district names a permanent replacement.

Why It Matters to You

The "Ed" chatbot was sold to LAUSD families as a personal assistant that would track grades and surface mental health resources, the same pitch vendors are making to your own district right now. A six-million-dollar contract and a superintendent's resignation are the visible costs of a deal that failed; the invisible cost is the two years LAUSD spent building trust in a tool that never delivered what it promised. Before your school signs onto the next AI platform with a similarly broad pitch, ask what happens to that trust, and to the contract, if the vendor folds.

Why This Matters
AllHere is not the only AI-education vendor with funding or governance problems. A purchasing decision built on a product demo, without asking who is financially and legally accountable if the company fails, is the exact gap LAUSD's contract exposed.
Around the Corner
Expect LAUSD's permanent superintendent search to become a referendum on how the district vets AI vendors going forward, and expect other large districts to quietly review their own AI contracts in response.

AI Feedback Tools Change Their Answer When They Know a Student's Race.
The Development

Stanford HAI researchers Mei Tan and Lena Phalen tested AI writing-feedback tools on identical student essays, varying only a single line describing the student's race, gender, language background, disability status, achievement level, or motivation. The feedback changed substantively depending on which description the tool received, according to their study, first presented at the International Learning Analytics and Knowledge conference in Bergen, Norway, in May and reported by Education Week in June. The paper, titled "Marked Pedagogies," found that large language models do not filter out demographic information the way a human teacher typically would; every detail in a prompt is treated as relevant to the task, including a student's name or background, whether or not it has any actual bearing on their writing.

Why It Matters to You

If you use an AI tool to draft or speed up feedback on student writing, the demographic context built into your gradebook or learning platform, a student's name, an IEP flag, an ESL designation, may be quietly shaping the feedback that tool generates. The bias is not necessarily intentional on the vendor's part; it is a structural feature of how these models process context. The practical move is to read AI-generated feedback with the same scrutiny you would apply to a substitute teacher's comments, not to treat it as a neutral baseline.

Why This Matters
This is the first study to isolate demographic framing as the variable changing AI feedback quality while holding the actual writing constant. It moves the bias question from a hypothetical risk to a measured effect.
Around the Corner
Expect AI-education vendors to face new pressure to disclose what student data their feedback tools actually use, and to explain why a tool needs to know a student's race to evaluate an essay in the first place.

Utah's Bell-to-Bell Phone Ban Becomes Law in Eight Days.
The Development

Utah's enhanced school cellphone law takes effect July 1, prohibiting phone use from the first bell to the last unless an individual school or district opts for a looser standard, according to the Deseret News and KSL. The law builds on a 2025 measure that banned phones only during class time, a restriction Governor Spencer Cox and many lawmakers, educators, and students argued did not go far enough. Senate Bill 69, School Device Revisions, passed the Utah Legislature in February. Utah joins a fast-growing list of states moving from partial to full-day restrictions; at least 31 states and the District of Columbia now restrict student cellphone use in some form, 22 of them with bell-to-bell bans, according to Education Week.

Why It Matters to You

A bell-to-bell ban changes more than what happens during your class period; it changes lunch, hallway transitions, and the moments between bells where students have historically self-regulated with a phone instead of with each other. If your school is moving toward this model, the open question is not whether students will comply during instruction, since most already do, but what replaces the phone during the unstructured minutes a full-day ban also covers.

Why This Matters
Utah's move from a class-time restriction to a full bell-to-bell policy in a single legislative cycle shows how fast the policy floor is rising nationally. A district policy that looked strict eighteen months ago may already be the most permissive option on the table.
Around the Corner
Watch how Utah enforces the gap between its default bell-to-bell ban and the looser opt-out it allows individual schools and districts to choose instead; that gap is where implementation problems are most likely to surface first.

The Bottom Line — Three Things for a High-Agency Professional
1 Before your district signs its next AI vendor contract, ask what happens to the money and the data if the company folds. That is the exact failure that turned LAUSD's six-million-dollar chatbot deal into a federal investigation and a superintendent's resignation.
2 Read AI-generated writing feedback with the same scrutiny you would give a substitute teacher's comments. Stanford's "Marked Pedagogies" study found the feedback itself changes when a student's race, gender, or disability status shows up in the prompt, even when the writing does not.
3 If your school is moving toward a bell-to-bell phone policy like Utah's, plan for what replaces the phone during lunch and hallway transitions, not just during class. That unstructured time is where Utah's law, and most ban debates, actually get tested.
