enhancing mathematical communication and self-efficacy through discovery learning approaches

E-worksheets developed with interactive features encourage students to explore mathematical concepts independently. this measures students' mathematical communication skills and self-efficacy using a discovery learning model assisted by e-worksheets. this research is a quasi-research conducted at mts negeri 1 yogyakarta. the sample was 64 class vii students who were divided into two sample groups, namely the experimental group and the control group. the e-worksheet assisted discovery learning model was applied to the experimental group and the conventional model was applied to the control group. the instruments used were mathematical communication ability test instruments and selfefficacy questionnaires. the t-test is used to analyze the effect of learning models on mathematical communication skills and self-efficacy. the research results found that students' achievement of mathematical communication skills and self-efficacy were higher compared to the control group. the eworksheet assisted discovery learning model has a significant influence on students' mathematical communication skills and self-efficacy. these findings provide a significant contribution to current knowledge about the influence of the discovery learning model assisted by lkpd e-worksheets to improve students' mathematical communication skills and self-efficacy on lines and angles.
