Abstract

Misconceptions can affect students' understanding. Identifying misconceptions is an important first step in gaining an understanding of student learning. One of the instruments that can be used to diagnose student misconceptions is a four-tier diagnostic instrument. This study aims to develop a four-tier diagnostic instrument on the material of chemical equilibrium. This research is a research and development (RnD) research. The research stages consisted of: concept mapping, pre-test, identification of unscientific student concepts, developing prototypes, validating prototypes, and completing the final prototype. The product development stages consist of: analysis of learning tools, preparation of test question grids, writing of items, as well as reviewing and revising questions. The data analysis carried out included validity, reliability, difficulty level, and distractor effectiveness. The final product that is produced consists of 20 items on the sub-topic of dynamic equilibrium, equilibrium constant, and equilibrium shift. The results of content validation on two expert lecturers found that the four-tier diagnostic instrument on chemical equilibrium material was valid and suitable for use. In empirical validation, it was found that 3 items were invalid. The resulting test questions are reliable with a reliability score of 0.77. In general, this four-tier diagnostic instrument is at a moderate level and is an effective distractor. This shows that a four-tier diagnostic instrument on chemical equilibrium material can be used to diagnose student misconceptions.

Abstract

In the era of the ASEAN Economic Community (AEC), Indonesia was led to prepare competitive, skilled and expert human resources so that they could compete with other countries. Therefore, the preparation of teaching materials is ideal for optimizing the involvement of students in the learning process of chemistry especially the famous abstract voltaic cell material. The low ability of students to think formally leads to difficulty understanding submicroscopic aspects so that there is the potential for misunderstanding on the topic of this voltaic cell. The purpose of this study is to explain the analysis of the needs in the development of teaching materials on the topic of STEM-PjBL-based voltaic cells assisted with learning videos. This type of research is used descriptive research with open and closed questionnaire techniques. The results of the study found that teachers and students still use conventional teaching materials that have not been integrated with approaches and methods. In addition, these teaching materials have not used information and communication technology that is more in demand by students. Thus it can be seen that overall the development of voltaic cell textbooks based on specific approaches and methods is still needed with integrated information and communication technology.
