Abstract

The teacher-made chemistry test must have a good quality, due to the decision taken from the tests has an impact on the students. Therefore, the purpose of the research is to explore the quality of teacher-made chemistry tests such as item fit and person fit, item difficulty, and test reliability. The sample consisted of 356 senior students from senior high schools in Yogyakarta that were selected by cluster random sampling technique. The research used the teacher-made chemistry test consisted of 40 multiple choice items which were collected using documentation technique. Data were analyzed with Rasch Model using Winsteps 3.73 version. The result showed that all items in the teacher-made chemical test were proven to have good quality (fit model, good item difficulty, and good test reliability). Moreover, 18 students were identified as misfit persons. From the findings, the test can be used to assess the students’ learning outcomes, especially for the try-out of the final exam in senior high school. Besides, the students identified as person misfits should be further examined and receive teachers’ guidance.

Abstract

Good learning media are media that can facilitate students to understand the material. The selection of learning media must be in accordance with the characteristics of the teaching material. To facilitate explaining the atomic structure material that is abstract, we need a medium that can realize the material. This study aimed to develop an interactive animation learning media Chem is Fun based on quantum learning and determine the quality of the product. The development model used was the ADDIE model by adapting the development procedures, namely the analysis, design, development, and evaluation stages. This study involved one media expert, one material expert, three peer reviewers, and five reviewers to assess product quality. The instrument used in this study consisted of an advice sheet and a questionnaire. The results of the study state that the learning media product Chem is Fun based on quantum learning has good quality, so it can be used as a learning medium to help students' learning process on atomic structure material.
