Abstract

The lack of mathematics content in Indonesia that emphasized students^ proving abilities consequently gave students few opportunities to optimize their proving abilities. Teachers can reference other proof content, such as Isoperimetric Problem because this content uses elementary prior school mathematics content, namely algebra operations and the area and perimeter of Two-Dimensional Figures. Teachers might arrange Isoperimetric Problem through worksheets so students can comprehend this problem. This study aims to know whether there is an effect of using the worksheet, prior knowledge, and interaction between the worksheet and students^ prior knowledge on students^ ability to prove the Isoperimetric Problem on Two-Dimensional Figures. This study used a quasi-experimental nonequivalent control group design and involved two classes in a second-year high school class at one of the high schools in Jambi City. The control class received instruction directly, while the experimental class received instruction utilizing a worksheet. Based on their prior knowledge, each class^s students split into three groups, high, medium, and low. The findings were examined using a Two-Way ANOVA with a significance level of 0.05, showing that using the worksheet, prior knowledge, and interactions between them impact students^ proving ability to prove the Isoperimetric Problem.
