Drawing flowcharts for simple abstract concepts

September 6, 2011 at 3:11 pm | Posted in Uncategorized | Leave a comment

Students developed flowcharts for various simple real-life situations like waking up to an alarm clock, going to the movies, going to eat at Wendy’s and software tech support for seniors. All students were required to have a clear start, a clear end, multiple decision boxes and at least on iteration. There could be multiple ends, but there could not be duplicate end points. Students were very enthusiastic and many found interesting tools online to build their flowcharts such as Lucid and Gliffy. Others used Microsoft Word.

Not all students have gotten the concept of flowcharts, but the majority made above a 90 and many got full marks for their assignment. I think almost all of them can wrap their heads around the concept of abstraction now. I am planning a simple test for the students. I will give them an abstract concept and have them write pseudocode and draw a flowchart for it.

We’re going to be moving on to Scratch with Berkeley ’s Build Your Own Blocks (BYOB) in a week.
