Abstract

The research aims to determine the effectiveness of Chemistry Scrabble (Chemscrabb) games as Instructional Media on Fundamental Laws of Chemistry to Students Learning Outcomes. This research is a research and development (RD) with designed by Posttest Only design, in which the design is based on the Thiagarajan technique. The research held on SMAN 10 Padang. Sampling selection was done by Random Cluster Sampling with the result that students of X-Science 2 as the experiment class and students of X-Science 4 as the control class. The data instruments used were a Post-test, questionnaire, and interview of two classes of the sample. The data analysis technique was a Hypothesis test by an Independent T-test sample. Based on Independent T-Test, the obtained tcount is 1.833, where the score is in the curve area, which means that accept H0 (there is no significant difference between the two samples). From the data, the research inference is that the utilization of Chemistry Scrabble (Chemscrabb) games as instructional media on Fundamental Laws of Chemistry for 10th-class sciences students is not effective for 10th-class sciences students' learning outcomes. However, students' activeness in the experiment class in the strengthening process (exercise) is higher than in the control class.

Abstract

This study focuses on the development of a POGIL-based experiment manual for general chemistry courses to enhance students' science process skills. The research and development (R&D) method, utilizing the Plomp model, was employed to create a valid and practical manual. Data were collected through a validity and practicality questionnaire, which was then analyzed using the Kappa Cohen's method. The manual's content was found to be highly valid, with an average score of 0.82, while its graphics had an average score of 0.84, also falling within the high category. Practicality was assessed through small group student testing, revealing high practicality scores in terms of user convenience, attractiveness, and benefits, with an average score of 0.77. Overall, the results indicate that the POGIL-based general chemistry experiment manual developed in this study is both valid and practical.
