One of the media and methods uses Cooperative Learning Jigsaw Type module development assisting the students to cooperate each other and ease them in comprehending the learning materials. Research Objective: To find out the improvement of students’ knowledge and attitude before and after the provision of Cooperative Learning Jigsaw Type module. Research Method: The research design used quasi-experimental with pre-test post-test with control group approach. The research samples were semester IV students of class A who were 49 students as the intervention group and class B who were 50 students as the control group. The analysis techniques used were descriptive test, Chi square, Paired T-Test, and Independent T-Test. Research Result: The research results show that Cooperative Learning Jigsaw Type module development can improve knowledge (p=0.000). However, it does not improve students’ attitude (p=0.061). There is no significant difference on the knowledge between the intervention and control groups (p=0.229). On the other hand, there is a significant difference on the attitude between the intervention and control groups (p=0.018). Conclusion: Cooperative Learning Jigsaw Type module development does not improve the knowledge but it improves the attitude of semester IV in Pediatric Nursing subject.
