We have evaluated the difference between using Python (this could be seen as 
the tool) and java to teach programming to beginners. Such evaluation is based 
on the analysis of student assessments. The aim of the comparison is to 
quantitatively measure a student’s ability to master basic programming concepts 
when Python is used instead of object-oriented Java. Both assessments consisted 
of students having to implement a program. For further details, the paper can 
be accessed below:


I hope this helps.

Subject: Re: evalutation of new tools to teach computer programming

Thanks a lot Thomas and John for your suggestions.

To better clarify my settings, I have two new tools (aiming at
teaching two different topics: general programming the first, sorting
algorithms the second) that I want to compare against NOT using the

Do you have any references to similar evalutations?
