Hate to be a killjoy, but I just looked at one of the Code.org activities for programming turtle graphics in App Lab.
As someone who has taught various dialects of Logo to kids and teachers for 34+ years, I was horrified by the missed learning opportunities and design of the activity. My concerns are in lesson/interface design and lost learning opportunities.
First of all, you connect any blocks and then hit Next. It doesn’t matter if you solve the actual problem posed or not.
Second and MUCH more importantly, ALL of the power and intellectual nutritional value of turtle geometry is sacrificed in order to teach a much simpler lesson in snapping blocks together in service of “efficiency.”
The power of turtle geometry is well – geometry, also measurement, and number. There are no numerical inputs to the turtle geometry blocks and all of the turns are in 90 degree increments.
As we approach the 50th anniversary of Logo and are celebrating the 35th anniversary of the publication of Mindstorms – Children, Computers, and Powerful Ideas, it sure would be nice if Code.org would learn some fundamental lessons of children, computers, and powerful ideas instead of depriving kids of an opportunity to learn mathematics while learning computer science.
Since posting the above statement to a CS discussion forum on Facebook, Hadi Partook – founder of Code.org responded as follows.
- Low engagement
- Limits on student creativity, exploration, and tinkering
