Abstract

The purpose of this research is to produce an estimate of the learning trajectory of flat shapes that is formed in the learning process in the field through a realistic mathematics education approach in class VIII of junior high school. The type of research used is a design research type validation study with stages, namely preliminary design, prerototyping phase and assessment phase. However, this research is only a preliminary design stage which is based on a realistic mathematics education approach. Design research aims to develop local instruction theory (LIT) by involving researchers and educators collaborating and collaborating with each other to improve the quality of mathematics learning, especially on flat-shaped materials. Learning mathematics requires a learning process that is associated with events, objects, and others that are close to the lives of students. This learning process is not obtained in a short way but requires a good preparation process in conveying the material to students. The preparatory step is carried out by designing learning that is formed according to the characteristics of the students so that in delivering the material it will run well and according to expectations so that learning objectives are achieved. The preparatory step in question is to make a local instruction theory (LIT) design. This article will only describe local instruction theory (LIT) in learning activities in the form of activities carried out by students to achieve learning objectives, namely to understand the concept of flat shape from the mindset different students
