Google Ties Gemini, NotebookLM, and Classroom Into One Learning Loop

Google is rolling study notebooks into Gemini this week, alongside no-cost full-length practice tests from The Princeton Review and an expansion of Gemini in Google Classroom to students of every age. The features, announced ahead of the ISTE conference in Orlando, are the company’s most ambitious move yet to stitch Gemini, NotebookLM, and Classroom into one connected learning loop.

Study notebooks are live now on personal Gemini accounts globally and reach school-issued accounts in the coming weeks. Free Princeton Review practice tests for the GRE, ACT, and Brazil’s ENEM follow on the same schedule, building on a SAT partnership that launched in January.

What Google Just Shipped to Classrooms

Study notebooks turn the Gemini app into an adaptive tutor. A student types a learning goal or uploads class materials, takes a diagnostic quiz, and Gemini builds a plan of bite-sized interactive lessons. As the student takes more quizzes, the lessons rewrite themselves to focus on the gaps, Google said in the full ISTE 2026 student features post. Study notebooks also sync with NotebookLM, so a student who lands on a tough concept can pull flashcards, infographics, and audio summaries from the same source.

Test prep gets the same treatment, at no cost. Google is partnering with The Princeton Review to launch full-length practice GRE and ACT tests in Gemini, plus ENEM practice for students in Brazil. Study notebooks already support the SAT, Google said, and more standardized tests are on the way.

Teachers get a new way to push all of this into the daily flow. Gemini in Classroom is opening up to students of all ages, grounded in the materials their teachers have uploaded and vetted with safety and pedagogy experts. Teachers will soon be able to assign a study notebook directly from Classroom and see where individual students or the whole class need help before the next exam.

The Loop Google Is Building Around the Student

The announcement’s center of gravity isn’t any single feature. It’s the wiring between them. Dan Fitzpatrick, who covered the launch for Forbes, grouped the rollout into three frames the company is leaning on: context, control, and insights.

Context starts with a new Google Classroom app inside Gemini. The app gives Gemini secure access to a teacher’s assignments, grades, and class materials, so it can spot misconceptions across the last three assignments or draft a cover lesson for a substitute. The Classroom app in Gemini is live globally in English for Google Workspace for Education users over 18. In the coming months, Google is launching a Classroom Model Context Protocol server so external edtech platforms like Canvas and PowerSchool Schoology can pull from the same source of truth. The same retrieval-practice technique that powers study notebooks underpins a wave of interactive learning apps for the 2026 school year.

Control sits with the teacher on a managed Chromebook. Using Class tools, a teacher can lock a student’s screen to NotebookLM for a research task or to a study notebook for revision, per Google’s parallel teacher-focused announcement. A new Guided Learning toggle makes real-time support easier to deliver without giving students a path to distraction.

Insights lands in the Classroom progress view. When a teacher assigns a study notebook in Classroom, the teacher sees progress across the class and surfaces the topics where reteaching will pay off before the assessment, not after a grade drops.

• 1,763 junior secondary math students in the Sierra Leone trial
• 113,000 student-AI interactions analyzed
• 91.4% of student conversations built conceptual understanding
• 2% of Gemini messages handed over a direct solution
• 1.2 to 1.7 years of typical math progress in an eight-week trial

What the Sierra Leone Trial Actually Showed

Google’s research arm is leaning hard on one trial to defend the rollout. DeepMind ran a pre-registered randomized controlled trial with partner Fab AI across 12 schools in Sierra Leone, tracking 1,763 junior secondary math students over eight weeks. Students using Gemini’s Guided Learning gained +0.258 standard deviations on math scores compared to a control group, Google said in the Sierra Leone trial results post. In practical terms, that’s roughly 1.2 to 1.7 years of typical math progress inside eight weeks.

Students in classrooms where teachers integrated Gemini into roughly half their lessons, hitting a 12-hour target, did even better: 1.8 to 2.5 years of progress. Engagement was the other surprise. Sixty-nine percent of students met or exceeded their usage targets, against the five percent typical of voluntary educational technology, a gap Google called The Five Percent Problem. By the final week of the trial, 90 percent of student queries were skill-building, up from 68 percent in week one, while solution-seeking dropped from 25 to 10 percent.

The trial gives strong evidence that carefully designed AI can help improve learning outcomes.

Conrad Sackey, Sierra Leone’s minister of basic and senior secondary education, gave the quote in a Forbes report on the launch. The caveat Google flagged in the same results post: students who entered the trial with stronger math skills gained the most, leaving the achievement gap largely intact. Google is now planning similar trials in other countries to test whether the result holds.

Free Full-Length Practice Tests Land in Gemini

Free, full-length practice tests for the GRE and ACT sit inside Gemini in the coming weeks, with ENEM support for Brazilian students on the same runway. The Princeton Review built the tests, and each one comes with a topic-by-topic performance breakdown after submission so students know where to focus next. The same Princeton Review partnership produced free SAT practice in Gemini, announced January 22, 2026, and that track is now folded into study notebooks.

“We are delighted to be the first test-prep services company to partner with Google on this innovative project,” said Robert Batten, CEO of The Princeton Review and its affiliate company Tutor.com, in a Princeton Review collaboration announcement. Batten framed the partnership as an equalizer, arguing free, structured prep with feedback could matter most for students who cannot pay for private tutoring. The launch also lands as schools weigh a growing field of AI tools purpose-built for student study stacks.

1. Now: study notebooks live on personal Gemini accounts globally.
2. Coming weeks: study notebooks on school accounts; free Princeton Review GRE and ACT practice tests; ENEM practice for Brazil.
3. Coming months: teacher-led activities in Classroom for Guided Learning, study notebooks, and NotebookLM; the Classroom MCP server; NotebookLM assignments in Canvas by Instructure; mobile support for study notebooks.

The Hardware Lock Behind It All

Most of the heavy teacher-side features live behind a paywall and a hardware requirement. Class tools, including Focus Mode and the screen lock, run only with Google Workspace for Education Plus or the Teaching and Learning add-on, and only when every educator and every student in the class uses a Chromebook. Schools running mixed-device fleets can’t use the lock to its full effect.

The Chromebook lock is also a strategic moat. The features teachers will find most useful require a Chromebook, and the Chromebook footprint in US K-12 classrooms is one of the largest single-vendor footprints in education. That footprint is now wired into the same AI feedback loop as Gemini and NotebookLM, and into the LTI connections Google is opening up to PowerSchool Schoology and Canvas.

For Google, the Classroom app inside Gemini closes a different loop: the company’s flagship chatbot can now read a teacher’s actual class materials without the teacher copying anything in. That grounding is what makes the safer Classroom version feel different from a student opening a generic chatbot and hoping for the best.

What Is Still on the Roadmap

Several of the headline features are still weeks or months from general availability. Teacher-led activities in Google Classroom, covering Guided Learning in Gemini, study notebooks, and NotebookLM, arrive in the coming months. The Classroom Model Context Protocol server, the bridge that lets Canvas, PowerSchool Schoology, and other platforms pull Classroom context into their own tools, also lands in the coming months. NotebookLM assignments in Canvas follow the same window.

Study notebooks themselves are desktop-only today, with mobile support expected later this summer. The desktop-first rollout is notable because the students who most need flexible study tools often study on phones. For now, the trade-off is clear: a deeper, NotebookLM-aware study experience on a laptop, a stripped-down Gemini chat on mobile.

Beyond the products, Google is investing in teacher training. The Google AI Educator Series, built with ISTE+ASCD, aims to make AI training available to all 6 million US educators. Adoption of any of this depends on teachers getting time and support to learn the new stack, not just access to it. Google has the tools. Whether schools are ready to use them well remains an open question.
