A Teaching Strategy of Computer Courses Based on “3 + 2” Competency Model

The concept of “competency-based learning” is proposed in the CC2020 report, which provides a new guidance for the training of computer professionals. This paper first analyzes the role of the concept in the teaching process and puts forward the “3 + 2” competency model. The model updates students’ cognitive structure twice through three teaching processes, so as to attain the three-dimensional competency training covering knowledge, skills and dispositions. Then, under the guidance of this model, the teaching strategy for computer courses is proposed which adopts the way of “Learning Maps”, uses MOOC to realize students ‘personalized learning, uses task-based teaching to realize students ‘participatory learning, and realizes the improvement of students ‘comprehensive literacy through cooperation and discussion. Finally, taking Python Language Programming as an example, two classes of first-year computer majors were selected for comparative experiments. The improvement of students’ competency in the dimension of knowledge and skills was quantitatively analyzed by comparing their scores, and the cultivation effect of students’ competency in the dimension of dispositions was analyzed by interviews. The result showed that the teaching strategy proposed in this paper can improve students’ competency level and get a good teaching effect.
