Abstract

The purpose of this research is to produce a test instrument to measure mathematical problem-solving ability by looking at the development procedures and the quality of the mathematics problem solving instruments developed. The research used is the type of research (R&D) that is the development of test instruments to measure the ability to solve mathematical problems. The development model of this research instrument is developed on the basis of the Tessmer model which is the formative type of evaluation, i.e. (1) preliminary stage, (2) self evaluation stage, (3) prototyping stage (expert reviews, one-to-one and small group) and (4) field test stage. The test subject of the experiment were X Students of SMAN 2 Bayah which amounted to 25 students. Based on the results of experiments conducted, it is found that: (1) math problem solving test instrument has been said "valid" because based on the CVR results are 1 and meet the criteria of  ≥ 0.99 and CVI is 1 with a category perfectly suitable or in the range 0,68-1,00 (2) mathematical problem-solving test instrument is said to be reliable with a value of 0.754 with high category, and is in the range of 0.60 < r11 < 0,80 (3)instrumen test the math problem solving device has a level of difficulty good then the average level of difficulty obtained is 0.58 with the medium category that is in the range of 0.31 to 0.70. (4) instrumen test math problem solving devices has a power a good differentiator and the average distinguishing power obtained is 0.35 with sufficient category or is in the range Dp > 0.2. As a result, the produced instrument is appropriate for assessing pupils' mathematical problem-solving abilities

Abstract

The study aims to produce e-module teaching materials based on Discovery Learning, supported by GeoGebra and LiveWorksheets, as well as to determine whether this e-module is valid, practical, and has a potential effect on students' problem-solving abilities. The research method used is Research and Development (R&D) with an ADDIE design. The research process consists of five stages: (1) Analysis (analysis of material needs, material analysis, and analysis of student characteristics); (2) Design (design or product framework to be made as an initial overview); (3) Development (development of the e-module and preparation of instruments to be used for valid, practical, and effective assessments); (4) Implementation (product review to be developed in classroom learning); (5) Evaluation (the product will be revised based on feedback given by the students to ensure the quality of the developed product is appropriate and adequate). The e-module learning materials were given to class X students of Senior High School. The results of the expert material validation obtained a percentage evaluation of 88%, indicating valid criteria. The test results showed that this e-module received a positive response from the students with an average percentage evaluation of 85%, categorizing it as highly effective. The material validation resulted in an 88% evaluation percentage, indicating valid criteria. The students' validation results obtained an 85% assessment percentage, also indicating valid criteria. The development of this module is worthy and suitable for use in schools by teachers to enhance students' conceptual understanding of quadratic equations and quadratic functions. Additionally, the module can develop critical thinking and problem-solving skills, which are crucial in 21st-century education.
