This paper proposes a sequence of learning activities (i.e. a learning script) supported by networked technologies for the application of the “model-first” approach in teaching object oriented programming (OOP). The “model-first” approach has been proposed and applied by various researchers and it seems promising for augmenting the learning effectiveness of OO programming instructional practices. This approach focuses on the conceptualisation of OO design models as well as the OO software development process based on these models, prior to exposing students to the programming language’s syntactic and semantic details. However, there is a lack of systematic evaluation studies of the application of this specific approach via a specific sequence of learning activities. The paper proposes such a sequence which involves three main phases: (i) observation of the development process of an exemplar OO software application (ii) problem solving tasks with guided instructions, and (iii) autonomous problem solving task. The proposed sequence of learning activities was tested during a two and a half months seminar for postgraduate students showing promising results.
