In week 5
Back to Greedy, starting with a short on Floats and the Fahrenheit lesson. This lesson is a new addition not part of the CS50 edx course. I love taking it from this angle and only talking about the floats here. That was a much better approach for my students.
Then a quiz on Tuesday, and the writing of our Greedy pseudocode. The quiz checked if they could call a directory independently, compile, run and use the correct syntax for a ‘for loop’.
At the end of the week I actually pulled the students on a different project. This project included reviewing a student survey within the district. The survey was anonymous but I shared the results via an .xlsx file. Then I challenged students to pull three pieces of information from the survey that was immediately apparent by looking at the results. For example, use a =Countif statement to see how many people used the word “stupid” when describing their classes. Or see use an =If statement to see if students that believe education in America is failing also play sports or don’t play sports. Are there any correlations. Essentially, we used some code to review a survey and draw some conclusions about our school survey. This was a neat opportunity to see how we can use the tool of programming outside our classroom. information about Excel formulas: http://www.gcflearnfree.org/excel2013/14
Oh, and since it wasn’t quite time for a feature flick we found some humor with the IKEA catalog video.
Looking ahead: continue Greedy
