Grading in the Age of AI: Why Human Learning Still Matters

Grading in the Age of AI: Why Human Learning Still Matters

As AI models like Gemini 3 and Claude Opus 4.5 continue to improve, many of us are left wondering: if the answer is free, what's the value of learning math in 2025? I've been testing these models on harder Linear Algebra problems from standard textbooks, and the results are impressive. But what does this mean for our education system?

Four New Whys for Math Education

• Auditor: We learn math to verify AI's claims. By understanding the underlying principles, we can spot when an AI is hallucinating or making incorrect assumptions.
• Architect: We learn math to design and build new systems. AI can augment our work, but human ingenuity and creativity are still essential for innovation.
• Practitioner: We learn math to solve real-world problems. AI can provide insights, but human judgment and expertise are necessary for practical applications.
• Philosopher: We learn math to understand the underlying nature of reality. Math is a language that describes the world, and human curiosity drives our pursuit of knowledge.

Verification: The Auditor's Perspective

One possible answer to the question is that we learn math to verify AI's claims. By understanding the underlying principles, we can spot when an AI is hallucinating or making incorrect assumptions. Let's consider a scenario:

You're working on a project that involves using AI to analyze data. You're given a report with some surprising results, and you're not sure if the AI is correct. What do you do?

One approach is to use your knowledge of Linear Algebra to verify the AI's claims. You can use mathematical techniques like eigenvalue decomposition or singular value decomposition to check the AI's assumptions. By doing so, you can ensure that the results are accurate and reliable.

Here's a step-by-step guide on how to do it:

1. Understand the problem domain and the AI's assumptions.
2. Choose a mathematical technique to verify the AI's claims.
3. Apply the technique to the data and check the results.
4. Interpret the results and make informed decisions.

For example, let's say you're working on a project to analyze customer churn. You're given a dataset with customer information, and you want to use AI to predict which customers are likely to churn. However, you're not sure if the AI's results are accurate. You can use your knowledge of Linear Algebra to verify the AI's claims by applying techniques like eigenvalue decomposition or singular value decomposition to the data. This will help you identify any potential biases or errors in the AI's results.

Takeaway: To verify AI claims, you need to understand the underlying principles and use mathematical techniques to check the AI's assumptions.

Designing New Systems: The Architect's Perspective

Another possible answer is that we learn math to design and build new systems. AI can augment our work, but human ingenuity and creativity are still essential for innovation. Let's consider a scenario:

You're working on a new project that involves designing a machine learning model. You're given a dataset and some requirements, but you're not sure how to approach the problem. What do you do?

One approach is to use your knowledge of Linear Algebra to design the model. You can use techniques like principal component analysis or singular value decomposition to reduce the dimensionality of the data and improve the model's performance.

Here's a step-by-step guide on how to do it:

1. Understand the problem domain and the requirements.
2. Choose a mathematical technique to design the model.
3. Apply the technique to the data and evaluate the results.
4. Iterate and refine the design until you achieve the desired outcome.

For example, let's say you're working on a project to design a new recommendation system for an e-commerce platform. You're given a dataset with customer information and product data, and you want to use machine learning to recommend products to customers. You can use your knowledge of Linear Algebra to design the model by applying techniques like principal component analysis or singular value decomposition to the data. This will help you identify the most relevant features and improve the model's performance.

Takeaway: To design new systems, you need to use mathematical techniques to reduce the dimensionality of the data and improve the model's performance.

Real-World Applications: The Practitioner's Perspective

A third possible answer is that we learn math to solve real-world problems. AI can provide insights, but human judgment and expertise are necessary for practical applications. Let's consider a scenario:

You're working as a data analyst for a company that's trying to predict customer churn. You're given a dataset and some machine learning algorithms, but you're not sure how to approach the problem. What do you do?

One approach is to use your knowledge of Linear Algebra to analyze the data and identify patterns. You can use techniques like eigenvalue decomposition or singular value decomposition to reduce the dimensionality of the data and improve the model's performance.

Here's a step-by-step guide on how to do it:

1. Understand the problem domain and the requirements.
2. Choose a mathematical technique to analyze the data.
3. Apply the technique to the data and evaluate the results.
4. Iterate and refine the analysis until you achieve the desired outcome.

For example, let's say you're working on a project to predict customer churn for a telecommunications company. You're given a dataset with customer information and usage data, and you want to use machine learning to predict which customers are likely to churn. You can use your knowledge of Linear Algebra to analyze the data by applying techniques like eigenvalue decomposition or singular value decomposition to the data. This will help you identify the most relevant features and improve the model's performance.

Takeaway: To solve real-world problems, you need to use mathematical techniques to analyze the data and identify patterns.

Understanding the Nature of Reality: The Philosopher's Perspective

A fourth possible answer is that we learn math to understand the underlying nature of reality. Math is a language that describes the world, and human curiosity drives our pursuit of knowledge. Let's consider a scenario:

You're working on a project that involves understanding the behavior of complex systems. You're given a dataset and some mathematical models, but you're not sure how to approach the problem. What do you do?

One approach is to use your knowledge of Linear Algebra to analyze the data and identify patterns. You can use techniques like eigenvalue decomposition or singular value decomposition to reduce the dimensionality of the data and improve the model's performance.

Here's a step-by-step guide on how to do it:

1. Understand the problem domain and the requirements.
2. Choose a mathematical technique to analyze the data.
3. Apply the technique to the data and evaluate the results.
4. Iterate and refine the analysis until you achieve the desired outcome.

For example, let's say you're working on a project to understand the behavior of a complex biological system. You're given a dataset with biological data and some mathematical models, and you want to use Linear Algebra to analyze the data and identify patterns. You can use techniques like eigenvalue decomposition or singular value decomposition to reduce the dimensionality of the data and improve the model's performance.

Takeaway: To understand the nature of reality, you need to use mathematical techniques to analyze the data and identify patterns.
