Abstract

This study is a development research that aims to produce STEAM-based electronic learning device on colloid material to increase student’s interest and learning achievement that are valid, practical and effective. The development model uses the ADDIE development model which consists of 5 stages : (1) the analysis phase includes curriculum analysis, student analysis, concept analysis, formulation of learning objectives, and task analysis; (2) the design, which includes the stage of selecting the format and initial design of the RPP, e-module and E-LKPD using the Canva application; (3) the device development stage by integrating STEAM aspects and following the Project Based Learning (PjBL) syntax; (4)the deployment stage is the testing phase of learning tools that have been validated by experts and have been revised by developers; (5) the evaluation phase includes the evaluation of learning devices after going through the trial phase. Analysis of the results of the validation of RPP, e-Modul and e-LKPD based on the STEAM PjBL model, namely 3.53; 3.80; and 3.77 very valid categories. Practical based on the practicality test by looking at the implementation of STEAM-based learning the PjBL model has an average value of M = 1.87 which means that it is fully implemented; the responses of students and teachers were very positive with a percentage of 90.91% and 85.25%. Learning Devices also meet the effective criteria because the class completeness reaches 84.85% and the n-gain results in increasing interest in learning are in the medium criteria.

Abstract

This study aims to analyze the effectiveness of handouts as an alternative to learning chemistry in improving student achievement. The method used in this article is a meta-analysis of several pieces of literature relevant to the topic and research objectives. The handout was identified as having an optimal level of practicality, and was considered adequate for students because it made it easier for students in the learning process. The teacher's role in this method is more to strengthen the material by providing an understanding of the inappropriate material delivered by the group. The teacher and the students concluded the results obtained, and an assessment was carried out to determine the level of achievement of the cycle I. In the next stage in cycle II, the group assistants were expected to understand other students so that interactions between students were identified as contributing to the second cycle assessment results. The result is an increase in student achievement in both cognitive and affective aspects. The cognitive aspects previously at the level of achievement of 42.11% increased to 63.16% exceeding 60%. Meanwhile, the affective   aspect increased from 70.24% to 74.47%. The combination of discussion methods and handouts, and also videos as learning media can improve student learning outcomes or student achievement more effectively.
