Measuring instruments

An important goal of ours is to develop validated and reliable measuring instruments for computer science educational research purposes.

The instrument "Alex the robot" currently consists of seven items in a unified format.
It tests the ability to apply the imerative control structures (sequence, loop, condition) and uses an easy to understand pseudo-programming language which is explained beforehand.

The first preliminary results indicate that this test measures a one-dimensional psychometric construct and that the itesm are Rasch-scaled.
