This research aims to analyse whether the increasing use of case-based learning (CBL) by madrasa aliyah teachers in Indonesia improves their teaching skills in the field of education. This study employed a quasi-experimental technique and data from a CBL intervention programme to investigate how CBL is connected with teachers' hybrid teaching skill. The data was analysed using the difference-indifference design. In general, the teaching skill of madrasa teachers is solely treated as a predictor of the practice of teaching Islamic religious education. Still, we discovered that the greater use of CBL in hybrid learning can favorably affect the teaching skill of madrasa teachers. CBL is positively associated with student involvement and teaching in learning among the madrasa teacher teaching skill subscales. However, according to our data analysis, students' favourable responses to Islamic religious education, and hybrid learning practices can moderate the link between CBL and the teaching skill of madrasa teachers. This study has significance for the CBL model's growth in strengthening the teaching skill of madrasa teachers in distance learning Islamic religious education.
