Pengaruh Model Pembelajaran Berbasis Masalah Terhadap Kemampuan Berpikir Kritis dan Hasil Belajar Siswa dalam Pembelajaran Tentang Sistem Reproduksi Manusia

Abstract

This research was conducted to know the effect of application of problem based learning model on the critical thinking ability and student’s learning achievement in instruction of human reproductive system in class IX SMPN 16 Mataram in 2015. The population of this research were all students of class IX SMPN 16 Mataram. Class IX-D as a sample of this research was determined using simple random sampling. A product moment correlation was applied for data statistical analyzis. The results showed the values of r_count were 0.53, 0.38  and 0.31 for indicators of analyzing, recognize and solve problems and concluded, respectively. While indicator of learning achievement on knowledge had r_count = 0.07 and indicator understanding r_count = (0.35). Based on the results of significance test for the value of r_count on significant level of 5%, there were two indicators of critical thinking ability that were significant, namely analyze and recognize and solve problems. The other three indicators conclude, knowledge and understanding were non significant. This research concluded that the application of problem based learning model in the instruction of human reproductive system can affect the critical thinking ability and tendency affect learning achievement of students class IX SMPN 16 Mataram in 2015. Therefore, the problem based learning model can applied in the instruction of human reproductive system in class IX Junior High School.
