Quantifying patterns and programming st...

Pupils are often first exposed to programming in block-based programming environments like Scratch. Identifying and measuring the previous experience of students learning to program is a key to improve the teaching of programming. In this contribution, we outline an approach to measure and evaluate programming interactions with the block-based programming environment Scratch. First results, obtained with eight upper secondary school students, show that programming skills and patterns can be quantified with interaction metrics measured during program construction. The aim is a more fine-grained identification and assessment of programming skills.
