26 Students from Ecole des Mines working on phratch !

This was our first session on Phratch. The main goal of this course is to program the Lego Minstorm Ev3. The course is a sequence of 6 sessions.

In this first session, we were interested only on the software part: the students learned how to use Phratch, how to use blocks, variables, how to make a block…

The goal for them was to build the famous game: a Pong-like !

We also addressed an interesting point in software engineering: how to report a bug. Yes, you know that Phratch is in development and the current version is instable. So the idea for the students is: when they found a problem, there had to reproduce it at least one time and only afterthey reproduced it they call the teacher. The teacher validate the bug, then the student had to write a small bug report on a post-it and paste it on the white board.

Why a post-it ? It is small, and make the student thinking about what is important to write. It allows them to develop the deductive reasoning skill.

Phratch is clearly more stable than I expected. Now, we need to make it faster !
Let’s go for Phratch3.0
