Abstract

The purposes of this research are to increase creative thinking skills and concept mastery of students in the material buffer solution using Problem Based Learning (PBL) model. The method which is used quasi experiment method with one group pretest –posttest design. The research subjects were 31 students in grade XI school stubs on one of the main international school in the town of Cimahi, West Java. The techniques of data collection are done through a written test like 12 essay question, student worksheets, student questionnaires and teacher interviews. The data is analyzed by statistical tests using SPSS version 16.00 and a descriptive analysis. The results showed that the learning process according with 5 stages in the PBL model; over all creative thinking skills and concept mastery increased significantly with the average N-gain = 0.61; indicators of creative thinking skills that experienced the highest increasing is “elaboration”, N-gain = 0,70; label concepts that experienced the highest increasing is the calculation of pH buffer solution, N-gain=0.86 and PBL model got a positive response from teachers and students.

Abstract

The COVID-19 pandemic is a new situation that brings challenges to all sectors, including education. One of the impacts is that there is an adjustment in the implementation of learning, including practicums, which are usually held offline, turning into online learning. In this study, an analysis of the implementation of biochemistry practicum was carried out for two semesters during the Covid-19 pandemic. This study uses a descriptive case study design. Research data obtained from document analysis and questionnaires. There are five classes used as samples of this study. Questionnaires were given to 116 students. The results showed that the implementation of the biochemistry practicum had been carried out well. This is marked by positive responses from students through questionnaires. Even so, there are significant differences in student achievement compared to conditions after the pandemic. This shows that practicum activities, especially those related to laboratory skills, cannot be facilitated with online learning
