Abstract: For the majority of undergraduate students of computer science, inadequate designing and planning algorithm skills are among the most salient hurdles. Learning how to design an algorithm which resolves a given problem is not easy. We propose a formative-diagnostic assessment approach which helps students on acquiring problem-solving skills that enable them to cope with problems and to design more efficient and elegant solutions. This method is based on using known components called: basic operations, which are defined and regrouped in a library. A plan-based programme understanding is used for modelling and a similarity measure is chosen for matching between plans to assess.
