Modelling competency in the field of OOP: From investigating computer science curricula to developing test items

Abstract

In this paper, we describe the results of a thorough analysis of 44 K12 computer science curricula and standards documents conducted as part of an ongoing research project aiming at the development of a competency structure model and measurement instruments in the field of object-oriented programming (OOP). The curricula analysis builds upon a first model draft derived theoretically from a literature analysis in prior work. The model draft is 4-dimensional and consists of the four competency dimensions (1) OOP knowledge and skills, (2) Mastering representation, (3) Cognitive processes and (4) Metacognitive processes. We used these dimensions and the belonging sub-dimensions as a coding scheme and coded competency facets concerning OOP contained in the curricula and standards documents using the method of qualitative content analysis according to Mayring. This way, we could firstly successfully prove the curricular validity of our model draft and secondly, after a step of paraphrasing the identified competency facets, use these descriptions to initiate the process of item development to operationalize our competency model draft.
