Problem-Based Learning Using E-Module: Does It Effect on Student's High Order Thinking and Learning Interest in Studying Geography?

Higher Order Thinking Skills (HOTS) are abilities that students in the 21st century must acquire. Problem-based learning (PBL) is one of the learning models to improve HOTS. In this study, PBL is integrated with technology through the use of e-modules. The taxonomy of Marzano is the framework used to assess HOTS. Student learning interest in studying geography as a moderate variable is a form of research refreshment that will result in a shift in research trends on PBL. Geography is the main focus of education in the 21st century, especially related to environmental issues. This study aimed to determine the effect of PBL with e-module based on HOTS to student's learning interest in studying geography. The research population consisted of second-year students (grade 11) of social class in SMAN 2 Semarang (Public Senior High School). The number of each student in the experimental class and control class is 32 participants. This research used a factorial experimental design. The data was collected using a test measuring HOTS and a questionnaire measuring enthusiasm for learning geography. The data were analysed using statistics, including the normality and homogeneity test, and hypothesis testing with the T-test, linear regression, and two-way ANOVA. The results found that: (1) PBL with e-modules had a significant effect on HOTS; (2) student's interest in studying geography had no significant effect on HOTS; (3) there was no effect between PBL and e-modules with student's interest in studying geography on HOTS. The HOTS test results were unaffected by the increase or decrease in student's interest. The HOTS is not influenced by student's interest in studying geography, but rather by the actual learning; (4) the highest indicator of developing HOTS is the capacity for abstract thought; (5) students conclude that using e-modules in PBL can improve interest for solving environmental issues. The combination of e-module content with project-based learning motivates students to protect the environment. Subsequent studies can focus on research on hybrid-based PBL as an innovation in 21st century learning.
