Development of Mathematics Tests for Higher Order Thinking Skills on Quadratic Equations and Functions

Abstract

This research aims to produce valid and reliable phase E mathematics higher-order thinking Skills (HOTS) questions on quadratic equations and functions. The research conducted by researchers in development research with the development model used, namely the type of development studies with two stages, namely preliminary and formative evaluation. The subjects of this study were students of class X SMAN 2 Karimun. In this study, the average score of the assessment of the three aspects (material, construct, and language) by the three validators was 86.16%, with a very valid category. In contrast, the average of all statements in the student response questionnaire was 88.33% with very good criteria and had a reliability value of 0.89 with a high category. This study concluded that the resulting 22 questions of Higher Order Thinking Skills (HOTS) mathematics phase E on the material of equations and quadratic functions developed have met the valid and reliable criteria.
