Abstract

This study delved into the attitudes of 90 level 300 preservice teachers towards problem-solving in mathematics education, recognising its significance in enhancing students’ mathematical proficiency. Conducted through a cross-sectional survey design, the research encompassed preservice teachers from various specialities, including Junior High School, Upper Primary, and Early Grades in a college of education in the Upper West Region of Ghana. Utilising a structured questionnaire, rate their agreement or disagreement with the 27-item attitudinal scale on a four-point scale, ranging from 1 (strongly disagree) to 4 (strongly agree). The scores were interpreted as follows: a score of one represents the lowest possible level, indicating a negative attitude, while a score of five represents the highest possible level, indicating an assertive positive attitude. The attitude scores had a standard deviation of 5.19085, suggesting moderate variability from the mean. The attitude ratings displayed a negative skewness of -0.967, indicating that most preservice teachers had predominantly favourable attitudes towards problem-solving as a teaching method. Notably, the research found no significant differences in attitudes between male and female preservice teachers, nor across different programs of study, indicating the need to consider additional factors influencing attitudes towards problem-solving in mathematics education. The lack of significant differences in attitudes based on gender or program of study suggests that factors beyond these demographic variables may influence preservice teachers’ perceptions of problem-solving

Abstract

The Gaussian elimination method of solving four variables of simultaneous equations involves eliminating some elements of the simultaneous equations in triangular form to zero to determine the values of the variables of the simultaneous equations. This approach does not involve a matrix in generating the values of variables of the simultaneous equations. There is a need to develop a matrix model for solving four variables of simultaneous equations. The pattern of the developed model can be extended by solving three variables and two variables of simultaneous equations. This study develops Kifilideen’s Elimination Matrix Model to solve simultaneous equations of four variables w, x, y, and z, three variables x, y, and z and two variables x and y. The elimination method was gradually used to reduce the number of variables of a given simultaneous equation in matrix form. In contrast, in the process, Kifilideen’s Elimination Matrix Model was generated to solve the values of the variables of the simultaneous equations. The Kifilideen’s Elimination Matrix Model was implemented in solving four variables w, x, y, and z, three variables x, y, and z and two variables x and y simultaneous equations. Kifilideen’s Elimination Matrix Model has been fully utilised, attractive, accurate, and easy to understand

Abstract

This preliminary research will be conducted at the beginning of the operations research course. Operations research is an extension of the topic of linear programming mathematics that is taught in high school. This research aims to describe the results of the work of operations research class students regarding how to design contextual problems and solve them using GeoGebra’s help. This research uses a qualitative approach, namely through in-depth observation of the results of student work on worksheets. After data analysis, it was found that in designing problems, students could produce realistic contextual problems using two variables and a single optimum solution type. Interestingly, they use contexts that are very close to current world trends, for example, Korean boy bands, culinary delights, types of flower arrangements, and so on. Meanwhile, in the solution process, using GeoGebra has proven to facilitate problem-solving by implementing the strategy and checking the results. They use the probe concept to find the optimum solution, and GeoGebra dramatically speeds up the process

Abstract

One of the most common dilemmas faced by students studying mathematics is whether to opt for group revision or self-revision. Given the increasing perception of mathematics as a challenging and less engaging subject, selecting the most effective revision strategy is crucial. This study systematically reviews existing literature to analyze the comparative benefits and drawbacks of group and self-revision in mathematics education. The research employs a systematic literature review methodology, synthesizing findings from academic studies that explore the cognitive, motivational, and pedagogical aspects of both revision methods. The analysis reveals that while individual preferences and learning styles play a role, group revision generally yields better academic performance, increased motivation, and enhanced conceptual understanding compared to self-revision. The findings have implications for students, educators, and administrators in optimizing pedagogical strategies to enhance mathematics learning outcomes

Abstract

This study aims to determine and describe the learning difficulties experienced by class VIII students of SMP Unimuda Pulau Arar in learning mathematics. This study uses a descriptive qualitative method. The subjects in this study were 3 class VIII students of SMP Unimuda Pulau Arar. Data collection techniques in this study were observation, tests, questionnaires, and interviews. Data analysis in this study used the Miles and Huberman data analysis technique. To obtain data validity, researchers conducted a credibility test with the triangulation technique. The results of the analysis in this study indicate that there are three categories of students who experience difficulties in learning mathematics, namely students with high, medium and low learning difficulties. Students with high learning difficulties have the characteristics of experiencing obstacles in understanding concepts, following instructions, and submitting assignments on time. They are easily distracted, even though they show good self-confidence when working on problems. Students with moderate learning difficulties have the characteristics of needing additional time to understand abstract concepts. In contrast, students with low learning difficulties generally meet the learning difficulty indicators with more consistent results

Abstract

This research aims to develop manipulative media for geometric nets to support geometry learning in junior high schools using the Borg and Gall model Research and Development (R&D) method. This media is designed to visualize concrete spatial concepts, increase student interaction, and support the achievement of the Independent Curriculum. Validation shows this media is curriculum-appropriate, mathematically accurate, and practical even though it requires increased durability of digital materials and illustrations. Practicality tests show this media is effective in making abstract concepts more concrete, increasing understanding of students with visual and kinesthetic learning styles, and motivating active involvement, although auditory students require additional guidance. Large-scale implementation shows that this media increases understanding of concepts, learning motivation, and makes learning more interesting. Recommendations include the use of more durable materials, the integration of digital technology, and teacher training to optimize its use

Abstract

This study aims to analyze the influence of using manipulative media on students' understanding of fraction operations at MIS Muslimin Ciririp. A quantitative method with an explanatory approach was employed, involving 28 students selected through simple random sampling. The instruments used were questionnaires and tests. Data analysis included the Kolmogorov-Smirnov normality test, linearity test, as well as correlation and regression tests using SPSS version 26. The normality test results showed that the data were normally distributed, with significance values for manipulative media and fraction operation understanding of 0.064 and 0.200, respectively. The correlation test revealed a very strong relationship, with a correlation coefficient of 0.750, indicating a significant correlation between the use of manipulative media and students' understanding. The linear regression test produced the equation Y=47.186+0.479X, with a determination coefficient (R²) of 56.2%. This indicates that 56.2% of students' understanding of fraction operations is influenced by manipulative media, while the remaining 43.8% is influenced by other factors. This study confirms that the use of manipulative media significantly enhances students' understanding of fraction operations. These findings provide valuable insights for developing effective mathematics teaching strategies in elementary schools
