Abstract

This research is a literature study on students' creative thinking skills. This study aims to analyze students' creative thinking skills using a stem-based simulation method regarding single and compound interests of North Rantau High School students. The research method used in this study is a qualitative descriptive method. The type of data used in this study is qualitative data, which is categorized into two types, namely primary data and secondary data. Sources of data obtained through library research techniques (library study) which refers to sources available both online and offline such as: scientific journals, books and news sourced from trusted sources. The results of the study concluded that through the STEM teaching method, students were accustomed to working on questions with many correct answers or many strategies that could be used to solve problems. After being given the final task in the form of problems, the researchers arranged students' creative thinking patterns and analyzed the results of students' creative thinking by emphasizing the creative thinking aspect.

Abstract

Statistics learning still largely uses conventional approaches that are not optimal in developing students' critical thinking skills. This study aims to examine the effect of the implementation of the Problem-Based Learning (PBL) model on improving students' critical thinking skills in statistics material. This study used a quantitative approach with a quasi-experimental design. Data collection was carried out through critical thinking ability tests given before and after the implementation of PBL in the experimental group, then analyzed using the Wilcoxon Signed Ranks test. The results showed a significant increase in students' critical thinking skills after the implementation of the PBL model. The statistical analysis produced a Z value = −4.545 with an asymptotic significance value (2-tailed) of 0.000 (α < 0.05), which indicates a significant difference between the pretest and posttest scores. These findings indicate that the PBL model has a significant effect on improving students' critical thinking skills in statistics learning. The results of this study are expected to provide theoretical contributions in the development of Problem-Based Learning as well as practical implications for teachers in efforts to improve the quality of statistics learning.
