OVERCOMING CHALLENGES IN MODERN CHROMATOGRAPHY LEARNING: ANALYZING STUDENT NEEDS FOR SCAFFOLDING-BASED INTERACTIVE MEDIA

Abstract

Modern chromatography is a crucial analytical technique in chemistry, yet it is often challenging for students to grasp. This difficulty arises from the complexity of the theory and the gap between theoretical concepts and laboratory practice. This study aims to identify the barriers students face in learning modern chromatography and to assess their needs for scaffolding-based interactive learning media as a potential solution. Using a qualitative descriptive approach, the research involved 43 students and alumni from the Chemistry Education Program at the Faculty of Teacher Training and Education, Universitas Terbuka. A questionnaire was employed to explore their understanding of the material, use of learning media, and independence in learning. The results reveal that students encounter significant challenges in comprehending modern chromatography theory, primarily due to limited access to learning resources, a lack of hands-on practice, and insufficient visual explanations. Scaffolding-based interactive learning media is considered capable of addressing these issues by providing clear visualizations, interactive exercises, and step-by-step feedback. The use of interactive media is expected to enhance both material comprehension and learning interest, while the scaffolding approach is deemed effective in helping students overcome difficulties in understanding complex concepts. The findings indicate that although respondents have high confidence in using technology, there are challenges in self-directed learning and the effectiveness of online tutorials. The study recommends the development of more adaptive and interactive learning media, as well as enhanced support in online tutorials to better meet student needs. By leveraging interactive learning media and the scaffolding approach, it is anticipated that students' understanding of modern chromatography will significantly improve, along with their ability to develop stronger independent learning skills.
