🎓 How Students Use AI at University — A Real-World Study of 1,000,000 Sessions from Anthropic

AI is increasingly permeating education, but most discussions have so far been based on surveys and lab experiments. In a new report, the Anthropic team conducted one of the largest studies of real-world student AI use, analyzing over 1 million anonymized conversations with Claude.ai.

🤔 Who Uses AI the Most?

✅Computer Science students are the clear winner: they make up 36.8% of all conversations with Claude, although in fact they only make up 5.4% of US graduates.
✅STEM disciplines dominate overall — students in science, math, and engineering use AI far more than students in business, medicine, or the humanities.
✅ Business makes up almost 19% of all degrees, but only 8.9% of all AI sessions. The picture is similar in healthcare and humanities.

🤔 Why students turn to AI: the most popular queries

✅Creating and editing educational materials - 39.3%
✅Solving assignments, coding, explaining theory - 33.5%
✅Analyzing and visualizing data - 11%
✅Assistance in research and tool development - 6.5%
✅Translations, proofreading, creating diagrams - the remaining percentages.

🤔How exactly do students interact with AI?

✅Direct problem solving
✅Direct content creation
✅Collaborative problem solving
✅Collaborative content creation

💡Interestingly, all 4 types are found approximately equally often (23–29% each).

⚠️ The issue of academic honesty and thinking

The study showed that Claude most often performs high-level cognitive functions according to Bloom's taxonomy in conversations with students:

✅Creation — 39.8%
✅Analysis — 30.2%
✅Application, understanding, and memorization — much less often

⚡️ All this turns the familiar "Bloom's pyramid" upside down — and raises concerns: are students starting to "delegate" critical thinking operations to AI too early?

💡This study is just the beginning of a long journey, but it already provides a lot of food for thought for teachers, students, and university administrators.

🔹 Lower ε = stronger privacy, but lower text quality.
🔹 Recommended range: ε = 1–5, balancing privacy & utility.

🚀 Key Privacy Mechanisms
✅ Noise addition to model log probabilities before token selection.
✅ Gradient clipping during training to limit the influence of individual data points.
✅ Query grouping to minimize privacy risks from multiple model interactions.

📊 Testing Results
🔹 Synthetic data retains practical utility for training downstream models.
🔹 Formal privacy guarantees (ε < 5) without significant loss in data quality.

🛠 Where Can It Be Used?
💡 Training AI models on sensitive datasets (e.g., healthcare, finance).
💡 Algorithm testing without access to real data.
💡 Data sharing between organizations without privacy risks.

⚖️ Pros & Cons
✅ Privacy without losing functionality – secure data without major quality loss.
✅ Ethical AI usage in sensitive domains.
❌ Trade-off between quality & privacy – stronger privacy can reduce text coherence.
❌ Increased computational costs – additional privacy checks slow down generation.

🤖 Conclusion

💡 Key ideas of the book:

✅Data Science ≠ magic. It is a tool for solving specific business problems, and not a reason to chase hype.
✅The role of business is key. The business customer must clearly understand the problem, constraints, and desired outcome.
✅It is important to ask the right questions. Not "which algorithm is better?", but "will this help achieve the goal on time and on budget?"
✅Technical skills are not required. But basic knowledge of data, model types, storage, qualities, and capabilities is desirable.
✅Ethics is not the least important. Models should not reinforce biases or discriminate.

🧠 Who will benefit from this:

✅Managers implementing analytics
✅Product managers and startup founders
✅Marketers and CFOs
✅Anyone who wants to effectively interact with data science teams

🤔General conclusion:
This book is a bridge between business and analysts. Without an overload of terms, but with a deep understanding of the processes.

📊 How to avoid data chaos? Ways to ensure consistency of metrics in a warehouse

If you work with analytics, you have probably encountered a situation where the same metric is calculated differently in different departments. This leads to confusion, reduces trust in the data, and slows down decision-making. The new article discusses the key reasons for this problem and two effective solutions.

🤔 Why do metrics diverge?
The reason lies in the spontaneous growth of analytics:
🔹 One analyst writes a SQL query to calculate the metric.
🔹 Then other teams create their own versions based on this query, making minor changes.
🔹 Over time, discrepancies arise, and the analytics team spends more and more time sorting out inconsistencies.

To avoid this situation, it is worth implementing uniform metric management standards.

🛠 Two approaches to ensure consistency

✅Semantic Layer
This is an intermediate layer between data and analytics tools, where metrics are defined centrally. They are stored in static files (e.g. YAML) and used to automatically generate SQL queries.

💡 Pros:
✔️ Flexibility: adapts to different queries without pre-creating tables.
✔️ Transparency: uniform definitions are available to all teams.
✔️ Relevance: data is updated in real time.

⚠️ Cons:
❌ Requires investment in infrastructure and optimization.
❌ May increase the load on calculations (but this can be solved by caching).

📌 Example of a tool: Cube.js is one of the few mature open-source solutions.

✅Pre-Aggregated Tables
Here, tables with pre-calculated metrics and fixed dimensions are created in advance.

💡 Pros:
✔️ Simple implementation, convenient for small projects.
✔️ Saving computing resources.
✔️ Full control over calculations.

⚠️ Cons:
❌ Difficult to maintain as the number of users increases.
❌ Discrepancies are possible if metrics are defined in different tables.

🤔 Which method to choose?
The optimal approach is hybrid use:
🔹 Implement a semantic layer for scalability.
🔹 Use pre-aggregated tables for critical metrics where minimal computation cost is important.

🎲 Conditional Probability: Updating Beliefs with New Data

As we receive new information, our perception of event probabilities changes. This is the core idea of conditional probability, widely used in machine learning, medicine, finance, and more.

💡 Simple Examples:
🔹 Drawing a King from a deck: 4/52. If we know the card is a face card, the probability increases to 4/12.
🔹 Rolling a 6 on a die: 1/6. If we know the number is even, the probability jumps to 1/3.

💡 Real-World Applications:
✅ Medicine – Evaluating test accuracy (sensitivity, specificity, false positives).
✅ Finance – Assessing market risks, default probability of borrowers.
✅ Machine Learning – Spam filtering, medical diagnosis, credit scoring.

📌 Bayes' Theorem allows us to update probabilities as new data arrives. For instance, a positive test for a rare disease doesn’t necessarily mean a patient is sick—probability depends on disease prevalence and test accuracy.
