Differential Course-taking Hypothesis Revisited

The use of ICT in learning mathematics is not something new in order to maximize students’ mathematical abilities, especially in this modern era of industrial revolution 4.0. One of the mathematical abilities that focus on students’ development is mathematical reasoning ability. Based on this, the purpose of this study was to determine the effectiveness of ICT learning that developed through Hippani Animator Software on students’ mathematical reasoning abilities. This is a quasi-experimental study with non-equivalent control group design involving 72 students in different classes. Learning in the experimental class was carried out using ICT conducted in computer laboratories while in the control class did not use ICT learning. The experimental class was given a treatment using ICT, while the control class was given a conventional method but with the same mathematical reasoning abilities. The research was conducted for grade VII students at the Public Islamic Junior High School called State of Madrasah Tsanawiyah (MTsN) 3 Kuningan to introducing statistical data presentation. The results showed that the mathematical reasoning ability of the experimental class was better than control class. It indicates that the use of ICT in mathematics learning is effective in developing students’ reasoning abilities.

Considering the objectives and standards of the mathematics learning process, mathematical reasoning is an ability that students are expected to have. Nonetheless, the mathematical reasoning abilities of Indonesian students are still inadequate, and learning resources are still inadequate. The researcher then tries to solve it by combining the problem-based learning (PBL) paradigm with the use of GeoGebra in the classroom. The aim of this research is to identify and analyze the effect of GeoGebra and Gender-assisted problem-based learning (PBL) models on students' mathematical reasoning abilities. The study involved 35 students of XI State Senior High School at one of the schools in Mataram City. The research instrument used a mathematical reasoning ability test consisting of five essay questions. The study applied a one-group pretest-posttest design to observe the increase in students' mathematical reasoning abilities. Mathematical reasoning ability tests were given before and after the implementation of the GeoGebra-assisted PBL model. Data analysis used descriptive statistics, paired t-tests, and independent t-tests. The results of the analysis show that improving students' mathematical reasoning abilities can be done by applying the GeoGebra-assisted PBL model in the classroom. Observation of the psychological aspects of Gender showed significant results in students' mathematical reasoning abilities.

Biological Correlates of High Mathematical Reasoning Ability

In this study, the ability of mathematical reasoning is measured based on its indicators, namely, drawing logical conclusions, providing explanations with models, facts, characteristics or relationships, estimating answers and solution processes and formulating valid arguments. This type of research is qualitative research using a descriptive approach. The research was conducted at MTs Negeri 5 Merangin. The subjects used in this study were 3 students who were taken from class VII-B.The results showed that students who have mathematical reasoning abilities SKP-01 have been able to meet all indicators of mathematical reasoning abilities. SKP-02 students with mathematical reasoning abilities are unable to meet the indicators of compiling valid arguments. And SKP-03 students are not able to meet the indicators of estimating the answer and the solution process and the indicators compile valid arguments. So the three subjects who have different mathematical reasoning abilities, have obstacles in fulfilling different mathematical ability indicators.Thus, efforts to improve children's abilities in learning mathematics, especially in their mathematical reasoning abilities, require the selection of appropriate learning methods, encouraging students to interact positively with fellow students and with teachers when learning, encouraging students to use logical reasoning in solving math problems.

The instruments used were tests and questionnaires. The legibility test results by distributing questionnaires obtained that students gave a positive response to the questions tested. From field trial, it can be seen that the average student is in the “quite well” category. The results of questionnaires and tests show that the tests developed are effective to measure students’ mathematical reasoning ability on the topics of Linear Equation System (LES) and matrix. Thus, this test is standard and suitable for use by lecturers in classroom learning.

Mathematical reasoning skills are essential in understanding mathematical concepts and solving problems. This study aims to examine the influence of learning discipline, mathematical anxiety, and self-efficacy on students' mathematical reasoning ability through critical thinking skills. The study utilized an ex-post facto research design with a sample of 100 eighth-grade students from UPTD SMPN 2 Barru. Data were collected through questionnaires on learning discipline, mathematical anxiety, and self-efficacy, as well as critical thinking and mathematical reasoning tests. The findings indicate that learning discipline, mathematical anxiety, and self-efficacy significantly influence mathematical reasoning ability both directly and indirectly through critical thinking skills. Moreover, students with high discipline tend to have better reasoning skills, while those with high mathematical anxiety demonstrate lower reasoning ability. The study suggests that improving students' learning discipline and self-efficacy while reducing mathematical anxiety can enhance their mathematical reasoning ability.
