A PISA-based Student Worksheet for Better Understanding of Mathematical Concept

A student worksheet is one of the teaching materials to improve student understanding in the classroom. However, many teachers could not effectively arrange and utilize it so that the learning objectives stated might not be reached. This study aims to generate a PISA-based student worksheet on valid and practical content and expose the effect on the ability to understand students' mathematical concepts. Using development research of a preliminary research, development phase, and assessment, the worksheet is composed. Besides, a test is used to determine the effectiveness of worksheets and another test is also to find out the effect of worksheets that have been made on the ability to understand mathematical concepts. As a result, this study has produced a valid and practical PISA-based student worksheet. The thing that is distinctive of this worksheet is that the question contains Sharing Task and Jumping Task. The result also shows that the worksheet could improve student understanding of a mathematical concept.
