Abstract

The aim of this research is to develop a mathematical test instrument based on Higher Order Thingking Skills for high school students. The research methods used in this research are research and development methods or Research and Development. (R&D). The data-gathering instruments for this search are teacher lift, student perception lift, observation sheet, interview guide, and the definition test of Higher Order Thinking Skills. (HOTS). The study was tested on 25 students of the eighth grade of high school, the test was carried out on the material of linear equations and linear inequalities of one variable. The results of the research show that: 1) the test instrument Higher Order Thinking Skills developed is valid and reliable, 2) has an average difficulty level for each type of question, and 3) the test instruments Higher order thinking skills (HOTS) developed fall into the category both in different power tests. So, the tool developed by the researchers deserves to be used as an assessment to measure the Higher Order Thinking Skills (HOTS) test for high school students

Abstract

This study aims to analyze the misconceptions experienced by grade XI-4 students at SMAN 1 Pasuruan in understanding matrix concepts, including operations such as multiplication, determinants, minors, cofactors, and matrix equations. The study employed a qualitative descriptive method, collecting data through tests and analyzing students’ responses. The findings revealed two primary types of misconceptions: notation and generalization. Notation misconceptions involved errors in using symbols, such as replacing vertical brackets with regular brackets for minors and cofactors or misapplying the positive and negative sign patterns in cofactor elements. Generalization misconceptions occurred when students misunderstood the rules of matrix multiplication, such as assuming the resulting order of multiplication follows the first matrix or incorrectly applying procedural steps to determine adjoints and inverses. The study recommends teaching approaches that emphasize conceptual understanding and the application of problem-based strategies. Varied practice questions and in-depth explanations linking procedural steps to foundational concepts are expected to improve students’ comprehension. These findings contribute to the development of effective mathematics teaching strategies to minimize misconceptions in matrix topics in the future.

Abstract

The results of the Program for International Student Assessment (PISA) show that the literacy of students in Indonesia is low. This shows that Indonesia is still far behind other countries. One of the reasons Indonesian students have low grades is the ineffective learning system in Indonesia. This investigation aims to produce a numeration liaison instrument of the social and cultural context in Banten for high school students. The methods used are research and development or Research and Development. (R&D). Using the Wilson, Oriondo and Antonio models. The results obtained were: 1) a numerational literacy instrument developed that is valid and reliable, 2) has an average difficulty level for each type of question, and 3) a numerational literature instrument developed falls into the category of both in different power tests. So, the tool developed by the researchers deserves to be used as an assessment to measure numerational literacy in the Banten cultural context.

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.
