Balaputra Dewa Museum in straight line equations

This study aims to present the initial results of the learning trajectory on the material of straight-line equations using the context of the Balaputra Dewa Museum by using numeracy skills test questions at the evaluation stage. This research design consists of three stages: Preparation for an experiment, Implementation, Retrospective Analysis. The learning trajectory is designed in the context of the Balaputra Dewa Museum. Data was collected through documentation, interviews, and class observations. The findings show that the context of the Balaputra Dewa Museum helps students easily understand the concept of a straight-line equation and how students analyze the collection graphs of the Balaputra Dewa museum. The learning trajectory consists of two activities. The first aims to introduce the concept of straight-line equations and find the slope of straight-line equations. The second aims to help students generalize the concept of a straight line equation to solve a problem. Finally, the research findings contribute to the further development of the learning trajectory on the straight-line equation material and the evaluation questions used in the form of students’ numeracy ability test questions.
