ABSTRACT
This research aims to test the effectiveness of the Web-Based Interactive Blended Learning (WBIBL) model in improving learning outcome in term of cognitive aspect in Programming Language Course. The research was a quantitative experimental model using one group pretest-posttest design which was conducted in Diploma 4 students in Electrical Engineering Department, Universitas Negeri Padang. Data collected by giving a pretest to a group known as the experimental class. Then treatment is given by applying the WBIBL model in teaching and learning, then given a posttest at the end of the lesson. The results of the study in terms of the cognitive aspects indicate that the learning outcomes of the students increased by 0.55 or 55%, where the average of pretest and posttest are 28.80%and 83.40%respectively. The results of this study indicate that the application of the WBIBL model on Programming Language courses could enhance the effectiveness of learning in terms of cognitive aspects.
