Abstract

The purpose of this study was to describe students' abductive reasoning in solving quadratic pattern generalization problem based on initial mathematical ability. Abductive reasoning is a process of drawing conclusions based on certain facts where the conclusion is still an assumption that can be revised based on new information. This type of research is descriptive research with a qualitative approach. The subjects of this study were 6 junior high school students based on the category of students' initial mathematical ability, namely 2 students with high initial mathematical ability, 2 students with moderate initial mathematical ability, and 2 students with low initial mathematical ability. The data collection technique was carried out through an initial mathematical ability test to determine the research subjects, generalization problems of quadratic patterns to identify students' abductive reasoning processes, and interviews. Data analysis was carried out based on the process and indicators of abductive reasoning. The results of the study showed that in the process of (1) realizing the existence of abductive problems, all subjects had never solved generalization problems of quadratic patterns so that the problem became a surprise because it was something new that was obtained, all subjects also found differences in generalization problems of quadratic patterns with number pattern problems that had been encountered before, all subjects carried out this process as an initial process of abductive reasoning; (2) identifying solutions, all subjects explained the discrepancy between the information obtained from the facts of observations and previous knowledge, namely students with high and moderate initial mathematical abilities explained the difference in the given generalization questions on quadratic patterns only presenting the 4th pattern, while the number pattern questions that have been encountered usually contain patterns 1 to 4 in sequence, students with low initial mathematical abilities explained the difference lies in the process of working on it; all subjects mentioned alternative solution guesses that might help to solve the problem, namely all subjects made guesses about different pattern shapes and determined the fixed difference in the number of black circles in each pattern; students with high initial mathematical abilities grouped the black circles into three shapes, using the quadratic formula, the first and second level arithmetic sequence formulas, and obtained two alternative solutions; students with moderate initial mathematical abilities used the first level arithmetic sequence formula and obtained one alternative solution; while students with low initial mathematical abilities did not get an alternative solution; (3) choosing the best solution, students with high and medium initial mathematical ability choose a certain solution from the alternative solutions provided and explain the reasons for choosing this solution as the best solution, while students with low initial mathematical ability do not; students with high initial mathematical ability choose one formula from two formulas obtained because this formula is easier; students with low initial mathematical ability only get one formula and choose this formula because it is easy to use (4) assimilating the chosen solution, students with high and medium initial mathematical ability use the chosen solution to solve the problem, while students with low initial mathematical ability do not; the solution used by students with high initial mathematical ability produces the correct answer, while the solution used by students with medium initial mathematical ability can be the right solution if it is adjusted to the estimated pattern shape that has been made. Keywords: abductive reasoning, initial mathematical ability, pattern generalization, quadratic pattern generalization problem.

Abstract

Proportional reasoning is the basis for understanding advanced mathematical concepts, but students in Indonesia still have difficulty in solving problems involving proportions and ratios. This study aims to describe the level of students' proportional reasoning in solving missing value problems with the help of GeoGebra. The research method used was qualitative with a case study approach, involving three students in class IX at one of the public junior high schools in Surabaya. The selection of subjects was based on mathematical ability, the same gender, and good communication skills. The research instruments included the researcher, mathematics ability test, proportional reasoning test, and interview. The results showed that students with high, medium, and low mathematics ability had reached level 2 in solving missing value problems using GeoGebra. The significant difference among the three students lies in the strategy used when solving the problem. This research has implications for students' proportional reasoning using GeoGebra. However, the results of this study do not represent the overall level of proportional reasoning of junior high school students.

Abstract

This research uses descriptive quantitative survey research. This study aims to determine the relationship between student perceptions of using DeepSeek on the effectiveness of mathematics learning. The sample in this study were 100 students majoring in mathematics at Surabaya State University. The sampling technique was carried out by means of probability sampling technique, namely simple random sampling. The data source of this research is the result of a survey conducted on the sample. In this survey, researchers used a questionnaire regarding students' perceptions of the use of DeepSeek on the effectiveness of mathematics learning with a Likert scale analyzed using Pearson's correlation analysis. The results showed that the correlation analysis between the independent variable (student perceptions in using DeepSeek) and the dependent variable (the effectiveness of mathematics learning) revealed a strong and positive relationship between the two variables. This means that there is a fairly strong and positive relationship between student perceptions of using DeepSeek and the effectiveness of mathematics learning.

Abstract

The low proficiency of Mathematics Education students in constructing mathematical proofs, especially using the principle of mathematical induction, highlights the need for enhanced learning approaches. One promising method is the integration of Artificial Intelligence (AI) into the proof process within Real Analysis courses. This study aims to describe how students carry out mathematical induction proofs with the assistance of AI. Ten voluntary students enrolled in Real Analysis participated in an initial test involving divisibility problem. From this group, two students were selected through maximum variation sampling based on their answer diversity and communication skills. One student employed a modulo-based approach, while the other used the divisibility-definition concept. Overall, the results demonstrate that AI significantly supports students in understanding problems, planning proofs, implementing strategies, and revising their reasoning. AI played a critical role in concept generation, solution evaluation, and embedded reflection across each stage of Polya’s problem-solving framework, combined with the three aspects of AI-assisted proof: construction, evaluation, and revision

Abstract

The quality of pre-service mathematics teacher education depends greatly on their understanding of mathematical problem-solving and its pedagogy. This study investigates pre-service teachers’ perceptions of the benefits of problem-solving in mathematics and the strategies they employ to solve problems. A qualitative design was adopted, involving 30 randomly selected participants from three Colleges of Education in Ghana. Data were collected through semi-structured interviews, transcribed, and analyzed thematically. Findings reveal that participants possess substantial knowledge of the benefits of problem-solving, including developing critical thinking and understanding, fostering intellectual challenge, enhancing real-life application skills, achieving set goals, overcoming difficulties, and selecting appropriate strategies. The study also highlights the range of strategies used by pre-service teachers, such as visual representation, logical reasoning, and varied heuristic approaches. These insights underscore the need to strengthen problem-solving pedagogy in teacher preparation programs to enhance both mathematical understanding and teaching practice.
