Improving Problem Solving Skills of High School Students Through The Implementation of Digital Module

This study aimed to evaluate the effectiveness of digital modules in enhancing high school students’ problem-solving skills in programming education. A quasi-experimental design with pre-test and post-test assessments was used to compare the outcomes between experimental and control groups. The study involved 60 high school students, divided into two groups: 30 students in the experimental group using digital modules and 30 in the control group relying on conventional methods such as lectures and PowerPoint presentations. The digital module was designed with structured tasks and collaborative coding activities to support analytical thinking and practical problem-solving. Data analysis, including independent sample t-tests and N-Gain calculations, demonstrated a significant improvement in the experimental group’s problem-solving performance. The experimental group achieved an N-Gain score of 85.2%, categorized as "high effectiveness," highlighting the module’s ability to enhance critical problem-solving skills. These findings indicate that digital modules are effective tools for improving problem-solving competencies in programming education. This study suggests that integrating digital modules into teaching practices can foster student engagement and skill development, addressing the needs of modern education. Further research is recommended to explore their long-term impact and application across different subjects.
