Abstract

Practicum guides are printed teaching materials that students can use in the learning process. This development research aims to determine the feasibility of an acid base-based practicum guide for environmental materials with a 3-D model and to improve student learning outcomes through practicum activities and the application of guided inquiry methods. The subject of this research was class XI IPA 1 at SMA Negeri 1 Tenga. The feasibility test for large groups has an average percentage of 88.24% which means that this practical guide is suitable for use with valid qualifications. Student learning outcomes using post test scores with the technique of statistical analysis of one sample t-test (one sample t-test). The results of the one-sample t-test hypothesis at a level of α = 5% were obtained tcount = 4.604> ttable = 1.708. The results of this study indicate that the guidelines for acid-base-based practicum for environmental materials are appropriate to be used in chemistry learning, and the use of acid-based practicum guides for environmental materials with the application of guided inquiry methods can improve student learning outcomes in acid-base material
