This study aims (1) to develop JIDI learning model in the course of Qur'an tafsir; (2) to evaluate JIDI learning model in the course of Qur'an tafsir. The approach of study uses mixed method with a descriptive-evaluative and experiment research designs to evaluate the JIDI learning model in the course of Qur'an tafsir. The population of study are all first semester students of Islamic Communication & Broadcasting Department, the Faculty of Da'wah and Communication at UIN Walisongo Semarang. The samples were class A to class H with amount 7 class first semester students. It uses stratified random sampling. Techniques in collecting data are questionnaire, interview, and test of Qur'an tafsir ability. The developing result of the learning model is carried out based on research about students' and lecturer's needs related to JIDI learning model. The evaluation of JIDI learning model is carried out based on the expert's assessment, the responses of lecturer and students, and suggestions from education practitioners until it is stated to be appropriate. The test result of Qur'an tafsir ability will be analyzed using t-test which has been tested for normality and homogeneity. Statistically, both Qur'an tafsir ability scores are different because F [subscript calculation] is 16.5875 while F [subscript table] is 3.91 at the significance level = 0.05. Since F [subscript calculation] > F [subscript table], it can be concluded that JIDI learning model gives significant influence in improving Qur'an tafsir ability. The implication of this study is that learning using JIDI model needs a long time, so it is suitable for the learning material with time allotment of eight meetings.
