Blog

I rarely write blog posts, but when I do, I like to post them here. Why? Because I can add whatever interactive components I want. I don't have a specific topic, so you'll find a variety of posts here of things that come to my mind (all CS related, of course).

• Teaching greedy algorithms with interactive components

  • algorithms

  I believe visualization is key to achieving deeper understanding of algorithms. That's why I have developed some interactive videos to help my students visualize the execution of sorting algorithms.

• Means, Medians and Images

  • education
  • statistics
  • image processing

  Means and medians are some of the first concepts we learn in any intro to statistics course. It turns out that it's pretty useful for image processing. Find out how in this post.

• The prompt coding mental model

  • programming
  • cs1

  In this post I discuss a hypothesis about a "prompt coding mental model" where students write code in a disordered manner, expecting the computer to figure out the correct execution.

• Teaching CS as an Interface Design Problem

  March 01, 2024

  • education
  • programming
  • cs1

  Teaching CS1 is not just about explaining concepts. It's about correcting students' mental models of how the computer works. We can think of teaching CS as an interface design problem.

• A Visual Tracer for Teaching Programming

  July 24, 2024 December 15, 2024

  • education
  • programming
  • cs1

  An idea for an IDE specifically designed for novice programmers, with a focus on visualizing the flow of execution in a program.
