This study aims to comprehensively examine the influence of the Problem-Based Learning (PBL) model integrated with the Internet of Things (IoT) on enhancing students’ problem-solving abilities in physics education. The integration of IoT into PBL is seen as a progressive approach to address the growing demand for innovative instructional strategies that promote higher-order thinking skills. A quantitative approach was adopted, utilizing a quasi-experimental design with a pretest-posttest nonequivalent control group format to assess the effectiveness of the intervention. The participants were 25 undergraduate physics students from the University of West Sulawesi, selected through saturated sampling due to the limited population size. To evaluate students’ problem-solving skills, data were collected using structured written tests designed around five key indicators: understanding the problem, describing the problem, planning the solution, executing the solution, and evaluating the results. Prior to hypothesis testing, normality of the data was assessed using the Kolmogorov-Smirnov test, followed by paired sample t-tests with IBM SPSS Statistics 23 to determine the significance of differences in pretest and posttest scores. The findings revealed a statistically significant improvement in students’ problem-solving skills following the implementation of the IoT-based PBL model, with results showing significance at the 5% level and gain scores classified as effective. These outcomes demonstrate the potential of the PBL-IoT integration to foster critical thinking and improve educational quality. Therefore, the implementation of this instructional model is recommended for physics educators seeking to enhance student engagement, problem-solving proficiency, and learning outcomes through the integration of emerging technologies.

The aim of this research is to obtain significant data and analyze the influence of the Team Assisted Individualization (T.A.I) learning model on the ability to solve mathematical problems on the subject of linear programming in class X students at MA Al Ittihad Sawangan Depok. The research method used is a quasi-experimental method (quasi-experiment). Sampling was carried out using a cluster random sampling technique with a research sample of 40 students, namely 20 students in class X IPS 2 as the experimental class and 20 X IPS 1 as the control class. The analysis technique used is a comparative analysis technique with the t-test, at a significance level of α= 0,05. The analytical requirements tests used in this research are the Chi-Square test for normality test and Fisher's test for homogeneity test. At a significance level of 0,05 with the Chi-Square test in the experimental class the price X2count <X2table (-33,38 < 9,488) while for the control class the price Homogeneity test at a significance level of 0.05 with Fisher's test, obtained F-count = 1,642 and F-table = 2,165 with a significance level of α= 0,05. Because Fcount < Ftable, H0 is accepted, so it can be concluded that the two classes have the same or homogeneous variance. Hypothesis testing uses the t-test with a significance level of α= 0,05. From the calculation results, t-count = 3,619, while ttable with degrees of freedom = 38 is 2,026, meaning t-count > t-table. Thus H0 is rejected and H1 is accepted. This research concludes that mathematical problem solving abilities using the Team Assisted Individualization (T.A.I) learning model are better than mathematical problem solving abilities using the Expository model.

This study aims to determine whether there is an influence of the problem-based learning model (PBL) with a STEM approach on the mathematical problem solving ability of grade VIII students of SMP Negeri 17 Medan. This research was conducted at SMP N 17 Medan T.A 2023/2024. The research method used is a quasi-experimental method. The sample of this study consisted of two classes, namely class VIII-3 as an experimental class taught with a PBL model with a STEM approach and class VIII-4 as a control class taught with conventional models. Based on descriptive statistics and categorization of research results, it was found that the mathematical problem solving ability of experimental class students was 67,74% of students in the high category, 32.26% of other students in the medium category, and no students in the low category. Meanwhile, in the control class, 15,63% of students were in the high level of problem solving ability, 53,13% were in the medium level and 31,24% of students were in the category low category. Thus it can be seen that the mathematical problem solving ability of grade students taught with PBL with a STEM approach is better than conventional learning models. Furthermore, with inferential statistical analysis for the t test, calculated t value = 2,42 and ttable = 1,999623, thus t calculated > t table means that the problem-solving ability of students taught with PBL with a STEM approach is not the same as students who use the learning  conventional model. With further analysis, Fcalculated = 5,6847 and F table = 3,998494482, then  calculated F > F table so it can be concluded that problem-based learning models with a STEM approach have a significant effect on students' mathematical problem solving abilities.
