Pengembangan Instrumen Tes Tertulis Berbasis Pendekatan Saintifik Pada Materi Sistem Gerak Kelas XI SMA
This study aims to develop a written test instrument based on scientific approach of the topic motion system on 11th grade in senior high school in October 2019 - January 2020. The research was conducted in two places, for validation and phase I limited trials conducted at Biology Education Campus FKIP UNRI and the test phase II limited trials were conducted at SMAN 8 Pekanbaru. This type of research refers to the R&D research approach using the ADDIE model developed by Dick and Carry. The subject of this research is the subject matter of Biology on 11th grade in senior high school KD 3.5. The written test instrument developed consisted of 5 meetings with an allocation of 15 minutes for posttest work and 2x45 minutes (2 JP) for daily test questions. The parameters of this study include the results of the validation of the development of a written test instrument by the validator and the response of the limited phase I and phase II trial evaluations. The assessment is done using a validation sheet and a questionnaire. Data analysis is descriptive qualitative and quantitative. validation results obtained an average overall score of posttest and daily test which is 3.41 categories are very valid (SV). The value of the results of the first trial to the overall posttest an daily test obtained an average score of 3.36 and 3.38 in the excellent category, while the second trial obtained an average score of 3.30 and 3.36 in the very good category. The results of the analysis of the items on the overall posttest and UH in the first trial obtained that the developed questions were well received with the details of the reliable items, the level of difficulty was dominated by moderate questions, the distinguishing power index was well received, and the percentage of effective deception items was 70% -100 % while the results of the analysis of items on the overall posttest and UH in trial II found that the revised items from trial I were in the well-accepted category with the details of the reliable items, the difficulty level was dominated by moderate questions, the power of differentiation was well received, and the function deceit 100% effective.
