Abstract

The ability to solve mathematical problems at SMP Negeri 1 Kibang is still relatively low, this is proven by test data show that 61.76% of students were able to understand the problem, 35.29% planned problem solving, 26.47% carried out problem solving, 0% checked again. The aim of this research is to determine the effect of the PBL model with the scaffolding method on the ability to solve mathematics problems in class VIII at SMP Negeri 1 Kibang. This type of research is a quasi-experiment with Post-TestOnly Control Design. This research was carried out at SMPN 1 Kibang with a population of 7 classes of class VIII students and the sample in this research was two classes taken using cluster random sampling. Before the instrument is used, its validity and reliability are first tested. The data collection method in this research uses a test method with test questions in the form of 5 essay questions. The data analysis used is a t-test where before carrying out the t-test it is necessary to carry out a prerequisite test analysis, namely the normality test and homogeneity test. Based on the results of the research and discussion, it was obtained that the value t_count> t_table or 4.90>2.003, it can be concluded that there is an influence of the PBL learning model with the scaffolding method on students' mathematical problem solving abilities at SMP Negeri 1 Kibang for the 2022/2023 academic year.
