Abstract

Chemistry is one of the fields of science with abstract concepts and unique vocabulary. That is why chemistry is considered as one of the subject matter that is considered difficult. Stoichiometry is one of the chemistry materials that is considered difficult due to its abstractness. This study aimed to develop and validate an interactive web-based learning media using Google Sites to enhance students’ understanding of stoichiometry. The research employed a Research and Development (R&D) method, including needs analysis, design, development, and validation stages. Data were collected in qualitative and quantitative forms, with quantitative data obtained through validation questionnaires using a 5-point Likert scale. The validation involved two expert validators, consisting of media and material experts. The results showed a validity score of 89% from media experts and 90% from material experts, with an overall average of 90%, categorized as highly feasible. The developed media includes interactive features such as virtual laboratories, learning videos, and 20 online quiz questions. These findings indicate that the Google Sites-based learning media is valid and suitable for supporting chemistry learning, particularly in improving students’ engagement and understanding of stoichiometry.

Abstract

This study aimed to develop STEM-PBL-based thermochemistry teaching materials and examine their validity and practicality for use in chemistry education. This research employed a Research and Development (R&D) approach using the ADDIE model, limited to the Analysis, Design, and Development stages. Following product development, expert validation and a limited practicality assessment were conducted. The research subjects consisted of three expert validators and 30 students from the Chemistry Education Study Program. The instruments used were validity and practicality questionnaires employing a four-point Likert scale. Validity data were analyzed using average validation scores, while practicality data were analyzed using the percentage of student responses. The results showed that the developed teaching materials obtained an average validity percentage of 93%, categorized as highly valid. The practicality assessment yielded a percentage score of 92%, categorized as highly practical. Students responded positively to the developed teaching materials, indicating that they were easy to use, attractive, and beneficial for supporting thermochemistry learning activities. The practicality assessment was limited to student responses and did not evaluate learning effectiveness. Therefore, the STEM-PBL-based thermochemistry teaching materials are considered highly valid and highly practical for use in chemistry education.
