IMPLEMENTATION OF PROBLEM-BASED LEARNING MODEL ON SALT HYDROLYSIS MATTER TO TRAIN STUDENTS’ CRITICAL THINKING SKILL GRADE XI-D SMAN 1 PAMEKASAN
Abstract: This research aimed
to develop students’ critical thinking skill on salt hydrolysis matter thatis
explored from feasibility of problem-based learning model, students’ activity,
and students’critical thinking skill. Critical thinking skills that were
trained were interpretation, analysis, andevaluation. It used research model of
One Group Pretest Posttest Design. The subject of thisresearch was students of
SMAN 1 Pamekasan grade XI-D. Results of research showed that (1)Feasibility of
problem-based learning model on meeting I, II, and III obtained average score
ateach phase between 3.00 – 3.80 on good and very good category (2) Students’
activity on meetingI, II, and III showed that it was suitable with syntax of
problem-based learning model and students had trained critical thinking skill based
on problem-based learning model (3) Problem-basedlearning could train students’
critical thinking skill, it could be seen from the development of critical
thinking skill of interpretation, analysis, and evaluation on posttest, 28
students achieved completeness and 9 students didn’t on interpretation, 29
students achieved completeness and 8students didn’t on analysis, and 29
students achieved completeness and 8 students didn’t onevaluation.
