Özet:

In this study, a collaborative inquiry-based blended learning model was developed. The model was supported by model books, learning instruments, and test instruments for problem-solving skills. The purpose of this study was to examine the effectiveness of the model to practice problem-solving skills for physics students. This research included research and development. The development model used uses the 4-D model (define, design, develop, and disseminate). The model and instruments were validated by the expert. The testing phase using the effectiveness test was carried out in one shot case study pre-post test design on three classes. The model implementation test was carried out on pre-service physics teachers at a private university in Mataram. Data collection was performed using observation sheets, problem-solving tests, and student response questionnaires. The data analysis technique used was descriptive, quantitative, and qualitative. The results showed that the inquiry collaborative tutorial-based blended learning model is effective in improving problem-solving skills. Students' problem-solving skills at the visualization step and describing the problem is high, while the next stage is still in the medium category. Students also gave positive responses to learning physics using this model.
