Abstract

The purposes of this research are 1) to describe the errors of thinking process of male student in solving group problems; 2) to describe the errors of thinking of female student in solving group problems. This research is an explorative research using a qualitative approach. Data collection is done by task-based interviews. The errors of thinking process based on indicators: fact errors, misconceptions, operating errors and principle errors in solving group problems. The data in this study are the results of interviews and group problem tests. The results of this research show that in fact errors, male subject experienced errors in interpreting the results obtained, whereas female students do not understand the symbols (H, #) and in the context of group symbols. In conceptual errors, the second subject is the same mistake, namely the error in explaining the group and the closed nature. Likewise, with operating errors, there is no significant difference in the second subject. In principle errors, the male subject does not associate the identity element obtained in the previous step in determining the inverse, while the female subject does not associate the set H and binary operations.

Abstract

Students are still not able to solve contextual questions that require the ability to reason well. Project Based Learning is a learning model that requires teachers and/or students to develop guiding questions (a guiding question). This research is a Classroom Action Research (CAR) with lecturers and first-semester students as subjects of mathematics education study programs at Majapahit Islamic University Academic Year 2022/2023. Data collection techniques were in the form of direct observation of learning activities, interviews with lecturers and students, tests of students' mathematical reasoning abilities, and documentation. Data analysis techniques in this study include 1) analysis of observational data, namely the activities of teachers and students during the process of learning mathematics; 2) data analysis of students' mathematical reasoning abilities test by paying attention to the mathematical reasoning scoring rubric. While the results of this study are that the application of the project-based learning (Pjbl) learning model has succeeded in increasing students' mathematical reasoning abilities, this is due to an increase in the average results of observations of the implementation of learning by lecturers and students as well as mathematical reasoning abilities in set material with project-based learning models from cycle I to cycle II

Abstract

This study aims to describe the process and the result of developing literacy and numeracy-based mathematical reasoning questions for high school students in Mojokerto that are valid, practical, and effective. The subjects of this study are 12th-grade students at the public senior high school of Gondang. The research instruments are observation sheets, interview guidelines, response questionnaires, and mathematical reasoning ability tests. At the same time, the data analysis in this study is qualitative and quantitative. The result of this research is (1) In The preliminary stage, students' mathematical reasoning abilities still needed to improve with evidence of difficulties in identifying and relating the information provided to conclusions. The researchers and teachers determine the research subjects and research time. In the formative evaluation stage, for self-evaluation, the researcher analyzed the material and curriculum. The third stage is prototyping, consisting of expert review, one-to-one, small group, and field tests. In the expert review, prototype II was produced, which was very valid, with an overall average of 4.24. Three students were tested in the one-to-one, and three prototypes were built. A trial was conducted in the small group, and a prototype IV was produced. The field test, testing, and production of mathematical modules met the valid, practical, and effective criteria. (2) The study's findings include numeracy and literacy-based mathematical reasoning problems that satisfy the validity criteria with proper categories and the practical requirements with extremely positive standards, in addition to achieving the efficacy criterion of the questions through students' mathematical reasoning.
