Three Short Lessons About Algorithms That I Used This Week

This week in my Computer Science Principles course we’re talking about algorithms. We started the week with an introduction answering the question, “what is an algorithm?” Then we looked at examples of algorithms that students encounter on a daily basis (YouTube suggestions being the one they related to the most). Today, my students wrote their own algorithms for automating processes of their choosing. 

As long-time followers of my blog know, I’m a proponent of using short videos and or sections of videos to provide students with an alternative to my explanations of concepts. This week I used three short videos to help my students understand what algorithms are and how they’re used. 

What is an algorithm?

There were two videos about that question that I shared with my students. First, I shared a TED-Ed lesson titled What’s an Algorithm? in my course’s Google Classroom. Second, in class I played GCF Learn Free’s two minute video Computer Science Basics: Algorithms.

How to Write a Trading Algorithm

This morning I played part of this video for my students. My point in doing so was to show them how algorithms can be written for all kinds of purposes including attempts at “outsmarting” the stock market. The other point was to show them that algorithms can be written in any language.
