Abstract

Purpose: This research aims to develop an environmentally based practicum E-LKPD (electronic student worksheet) on Chemical Equilibrium material to address laboratory facility limitations and produce a valid, practical product with potential to improve students' conceptual understanding. Methods: This study used the Research and Development (R&D) method with a 3D model (Define, Design, Develop) modified from the 4D model. Subjects were 11th-grade high school students, involving a small-scale trial (9 students) and a large-scale trial (27 students) selected via purposive sampling. Data were collected through expert validation sheets, student response questionnaires, and pretest-posttest questions, then analyzed using validity and practicality percentages and Normalized Gain (N-gain). Findings: The E-LKPD was rated very valid by media experts (95.83%) and material experts (94.44%), and very practical based on student responses (86.36% small-scale; 87.04% large-scale). Average N-gain of 0.90 (small-scale) and 0.92 (large-scale), both in the high category, indicated the E-LKPD's potential to improve conceptual understanding. Research Limitations: This research was conducted in only one class at one school without a comparison group, so generalizability remains limited and further research in a broader context is needed. Research Implications: This E-LKPD can serve as an economical, applicable, and environmentally friendly alternative teaching material for chemistry teachers, particularly in schools with limited laboratory facilities, enabling more contextual and interactive chemical equilibrium learning. Originality: This research develops an environment-based practicum E-LKPD integrating local environmental potential with interactive digital features for chemical equilibrium learning, an approach still relatively rare in previous studies.

Abstract

Chemistry learning on reaction rate material often faces challenges due to its abstract and complex nature, which can hinder students’ conceptual understanding and reduce their engagement in the learning process. These challenges are compounded by the predominance of lecture-based instruction and the limited use of interactive learning media. This study aimed to develop a Truth or Dare card-based learning media for reaction rate material and evaluate its validity, practicality, and effectiveness. The study employed a Research and Development (R&D) approach using a modified 4-D model consisting of three stages: define, design, and develop. The participants were 36 eleventh-grade students of SMAN 2 Sungai Raya, including 9 students in a small-scale trial and 27 students in a large-scale trial. Data were collected through observations, interviews, documentation, questionnaires, and tests. The instruments included material and media expert validation sheets, student response questionnaires, and pretest–posttest assessments. The results indicated that the Truth or Dare card media achieved a validity score of 96.66% from both material and media experts, categorized as very valid. The practicality scores reached 86.67% in the small-scale trial and 89.26% in the large-scale trial, indicating a very practical category. The effectiveness test showed N-gain scores of 0.84 and 0.91 in the small- and large-scale trials, respectively, both classified as high. These findings demonstrate that the developed media is valid, practical, and effective for enhancing student engagement and learning outcomes in reaction rate learning at the senior high school level.
