Abstract

Chemical equilibrium is considered abstract so it requires visualization by analogy through electronic modules combined with interactive multimedia teaching materials. This study aims to examine the influence of a guided discovery learning-based e-module on chemical equilibrium on the development of conceptual understanding and self-directed learning among 11th grade science students enrolled in the control and experimental groups. The research framework employed in this study follows a research and development (R&D) model. The participants were selected using the cluster random sampling technique. The e-module, developed based on GDL principles, was administered to 72 science 11th grade students through a quasi-experimental design involving a posttest-only control group. The research employed conceptual understanding test of chemical equilibrium and a self-directed learning questionnaire as data collection instruments. The disparities in conceptual understanding and self-directed learning between the control and experimental groups were assessed using the MANOVA (Hotteling's trace) test. There is a significant difference in both the overall and individual abilities of conceptual understanding and learning independence between students who used electronic modules based on GDL and those who did not, as indicated by simultaneous significance levels of 0.001 and individual significance levels of 0.009 and 0.004, all of which are smaller than 0.05.

Abstract

This research aims to create an instrument that can measure students' learning independence by measuring the level of validity and reliability. The instrument is a questionnaire for student learning independence consisting of 41 statements (20 positive statements and 21 negative statements) with responses based on a Likert scale score of 1 to 5. The research location for the empirical test of learning independence was at SMAN 1 Kalasan class XII MIPA in 3 classes. The number of empirical trial participants was 99 students. The results of the empirical test of the learning independence questionnaire instrument were then analyzed using the Winstep Rasch model program. The quality of the instrument can be determined from the unidimensional assumption test, the suitability test of the statement items to the Rasch model (item fit), and the bias of the statement items with the help of the Winstep program. The results obtained were that in the validity calculation there was 1 invalid statement out of 41 existing statements, namely the statement "I try to study as best as possible to achieve good performance" on the responsibility indicator. The reliability of the learning independence questionnaire instrument regarding the use of electronic modules is 0.93 and is in the very high category, so it can be concluded that the other 40 statements are declared valid and variable so that they can be used as instruments in measuring learning independence regarding the use of electronic modules.

Abstract

This study analyzes students’ learning difficulties in understanding biochemistry concepts, materials, and processes through a survey, and examines bibliometric patterns of biochemistry learning models and methods to identify potential alternative solutions. A descriptive research design was employed, combining survey methods and bibliometric analysis. The survey was conducted with 82 fourth-semester students of the Chemistry Study Program, including Class B (48 students) and Class E (34 students). Data were collected using an open-ended questionnaire and analyzed descriptively and qualitatively. In parallel, a bibliometric analysis of scientific articles on biochemistry learning difficulties was performed using VOSviewer software, identifying dominant sub-themes such as learning models, learning methods, and biochemistry education. The survey results indicate that students experience the greatest difficulties in protein biosynthesis (82%), lipid metabolism (55%), enzymes (53%), protein metabolism (50%), and carbohydrate metabolism (45%). These findings highlight challenges with metabolic pathways and molecular structures, emphasizing the need for visualization-based learning media. Additionally, the bibliometric analysis suggests that flipped classroom and blended learning approaches have strong potential as innovative strategies to address these difficulties. The study concludes with recommendations for future research focused on the development and evaluation of such approaches in biochemistry education.
