Effect Scientific Approach with Assistance of Student Worksheets based PBL towards Students’ Biology Affective Competence in Bacterial Learning Material

Abstract

Abstract Purpose this research to know effect scientific approach with assistance of student worksheets based PBL towards students’ Biology affective competence. This research is quasi-experiment using randomized control posted only design. Students class X is population. Purposive sampling is the technique, X IPA 4 (experiment) while X IPA 3 (control). The observation sheet was used as an instrument. Mann Whitney U test as data analysis. The results showed that there was a significant difference between the biological affective competence of experimental and control students, namely the biological affective competence of experimental class students was higher than the control class. The average experimental score 3.35 (B) and control 2.95 (C). The conclusion of this research is scientific approach with assistance of student worksheet based PBL on students enable them to increase their affective competence.
