The development of STEM-based discovery learning module in differential equations: One-to-one evaluation

Abstract

Differential Equation is a branch of mathematics that is closely related to the daily life problem. The learning of differential equations tends to be textbook oriented, not many use modules. Based on the needs analysis, it is necessary to develop a differential equation module based on Science, Technology, Engineering, and Mathematics (STEM)-Discovery Learning. The aim of this study is to describe the formative evaluation result of the STEM Discovery Learning Module though one-to-one evaluation. The research employs a design research. It was carried out in the even semester 2020/2021, and the research subjects were three college students of the Mathematics Education Study Program FKIP UMS. Data collection techniques used interviews and documentation. The data validity technique used source triangulation, and the data analysis technique used the flow method, which consists of data reduction, data presentation, and drawing conclusions. The research result shows that: 1) Module clarity: activity steps in STEM Discovery learning Module are clearly followed by students, the language is clear, communicative, and easily understood, mathematical symbols in the module are precise and clear, time allocation for each Discovery is sufficient. However, in Discovery I, the student found difficulty in solving the activity. 2) Module performance: module design, color, the font have attracted attention, and module presentation was coherent. 3) Obvious error: there are several obvious errors in the module. Some of the links are unclear, some mathematical symbols writing are inconsistent and unclear, there were question marks at the bottom of the symbols, and some sentences underlined in the module. The significance of the study is that the researcher can identify advantage and disadvantages of the STEM-Discovery Learning Module in differential equations from the student's point of view through one-to-one evaluation. The result can then be used to improve and perfect the module so that it will be ready to be evaluated in the next formative evaluation stages.
