The Effectiveness of Problem Based Learning (PBL) Model Assisted with Mind Mapping to Improve Critical Thinking of IPS Class V Students

Abstract

The results of the analysis of students’s report of fifth grade students at SDN Bangunharjo in the IPS subject were still below the KKM. This is related to the results of preliminary studies in the field which show that learning is still textual. There is a lack of HOTS questions to explore students' critical thinking processes and there was no study that presented a variety of situations to solve. This study aimed to analyze the effectiveness of the mind mapping-assisted PBL model to improve students' critical thinking. This research was conducted at Bangunharjo Elementary School, Semarang City. This type of research used quasi-experiments. The method used is a quantitative method. The entire population of class V at SDN Bangunharjo is 50 students. The research subjects were 25 students in the experimental class, class 5 B and 25 students in the control class, class VA. Sampling using nonprobability sampling with saturated sampling technique. Research data obtained from pretest-posttest, questionnaire, observation, and documentation. The data analysis used is the normality test, homogeneity test, sample t-test, gain test, and effective contribution. The results showed that the PBL model assisted by mind mapping was effective in increasing students' critical thinking: (a) the mean similarity results showed p = 0.988 and t count= 0.017, (b) completeness test, has result Sig value. showed a result of 0.05 ≤ 0.05, (c) the independent t-test showed a significance value showing the number 0.00 <0.05, (d) The n-gain result showed an average of 0.43. it conclusde, the problem based learning (PBL) model assisted by mind mapping is effective in increasing social studies students' critical thinking. For future researchers and for teachers, during the learning process the teacher should play an active role in providing direction and stimulus then students were able to learn independently and focus on learning. The problem-based learning model assisted by mind mapping can be used and developed in other learning materials and content to improve the quality of learning.
