Development of HOTS-Based Student Activity Sheet with an Open Ended Approach to Improve Mathematical Metacognition Ability and Self Confidence of Students of 20 Medan Junior High School

Abstract

This study aims to describe: 1) how the quality of HOTS-based student activity sheet with an Open Ended approach is quality; 2) increasing students' mathematical metacognition skills through HOTS-based worksheets with an Open Ended approach; and 3) increasing students' self confidence through HOTS-based worksheets with an Open Ended approach. This research is a development research. This research was conducted in two stages, namely the first stage of developing HOTS-based worksheets with an Open Ended approach using a formative evaluation type Tessmer development model, and the second stage testing HOTS-based worksheets with an Open Ended approach which was developed in class VIII-1 and VIII-3 SMP. State 20 Medan. From the results of trial I and trial II, it was obtained: 1) HOTS-based worksheets with an Open Ended approach to improve students' mathematical metacognition and self confidence skills that have been developed have met the valid, practical and effective criteria; 2) Increasing the ability of mathematical metacognition using HOTS-based worksheets with the Open Ended approach which has been developed as seen from the N-gain value in the first trial of 0.43 which increased to 0.47 in the second trial, meaning that it is in the "moderate" category; and 3) The increase in students' self confidence with the Open Ended approach which has been developed as seen from the N-gain value in the first trial of 0.46 increased to 0.51 in the second trial, meaning that it is in the "medium" category.
