In this study, a collaborative inquiry-based blended learning model (a system of learning used as an example to follow or imitate) was developed. The purpose of this study was to examine the effectiveness of the model to practice problem-solving skills for physics students. The development model used the 4-D model (define, design, develop, and disseminate). The product (blended learning model based on inquiry collaborative tutorial) was validated by expert and instruments were validated by Pearson product-moment correlation. There were 17 valid instrument items based on the results of the validity test, and these 17 question items were used to examine students' problem-solving skills. Data collection was also performed using observation sheets and student response questionnaires. The testing phase using the effectiveness test was carried out in one shot case study pre-post test design on three classes of pre-service physics teachers at a private university in Mataram. The data analysis technique used was one-way ANOVA, n-gain test and classical completeness analysis for the implementation of developed product-based learning. The results showed that the inquiry collaborative tutorial-based blended learning model was effective in improving problem-solving skills. Students' problem-solving skills at the visualization step and describing the problem is high category, while the next stage is still in the medium category. Students also gave positive responses to learning physics using this model. © 2020.
