Abstract

This study aims to determine that by using learning media based on gici-gici culture in mathematics learning for class VIII of SMP Negeri 5 Tanimbar Selatan. The design and approach in this study used a qualitative approach. This type of research is a study that describes data in the form of words and describes phenomena or facts obtained in the study. The subjects in this study were students of class VIII of SMP Negeri 5 Tanimbar Selatan. Data collection techniques used were research documentation, written tests and interviews and observation. Data analysis techniques used were data collection, data reduction, data presentation and data verification or drawing conclusions. The results of the study show that by implementing the gici-gici culture learning media in the learning process, it can increase the effectiveness of learning through the test results of students who follow the learning process as evidenced by the results of student tests classified into three aspects, namely low because the learning process of these students is rarely active and rarely attends school so that it has an impact on the completion of essay test questions that are not correct, medium because the completion of essay questions is wrong and does not follow the stages of solving the questions correctly and high because students are able to work on essay test questions by paying attention to the stages of solving the questions correctly and being active in the learning process.

Abstract

The production of payung geulis, a traditional craft from Tasikmalaya, is still largely carried out intuitively without considering the efficiency of capital use, raw materials, and working time. This condition often leads artisans to inaccuracies in determining production quantities, resulting in profits that are not yet optimal. This study aims to determine the most profitable production strategy through the application of a linear programming model using the Simplex method. A mathematical modeling approach was employed to describe the resource constraints faced by artisans, including capital limitations, raw material availability, and production capacity. Data were collected through direct observation and interviews, then formulated into decision variables representing the number of large, medium, and small umbrellas to be produced. The objective function was designed to maximize profit, while the constraints were developed based on material consumption, capital allocation, and production duration. The results indicate that the optimal solution is dynamic and depends on the profit per unit of each product type. In the first scenario, with a particular set of constraints, a maximum profit of Rp 6,000,000 is achieved when 400 large umbrellas are produced. In the second scenario, with a different profit structure, the maximum value of Rp 34,800,000 is obtained when production is entirely focused on small umbrellas totaling 2,320 units. These differences demonstrate that linear programming can determine the most efficient production strategy under varying resource conditions. Thus, the Simplex method proves to be an effective decision-support tool for artisans seeking to enhance profitability in a rational and measurable manner.

Abstract

This study was undertaken to ascertain the extent of the association between learning interest and mathematics achievement among eighth-grade students on the topic of proportion at SMP Negeri 21 Kota Bengkulu. The researcher employed a quantitative paradigm with a correlational design. A cohort of 28 students was designated as the sample through purposive sampling. Data were amassed using a learning-interest questionnaire adapted from Herdiyanto (2019) and a mathematics achievement test. The analytical procedure encompassed both descriptive and inferential statistics, preceded by prerequisite examinations comprising normality and linearity tests, followed by Pearson’s correlation analysis. The findings revealed that learning interest exhibits a remarkably strong and statistically significant nexus with students’ mathematics outcomes (r = 0.971; p < 0.05). These results underscore that learning interest contributes substantially to students’ academic attainment in the topic of proportion. Consequently, the study advocates that educators intensify strategies aimed at cultivating students’ learning interest to bolster their academic performance.

Abstract

This study aims to describe the critical thinking skills of seventh-grade students in solving word problems on algebra material from a gender perspective. This study uses a descriptive qualitative approach. The research subjects consisted of 29 seventh-grade students of SMP Negeri 20 Bengkulu City, with five students selected as the main subjects based on their level of critical thinking skills and gender representation. Data collection techniques included written tests, observations, interviews, and documentation. Data analysis was carried out using the Miles and Huberman model which includes data reduction, data presentation, and conclusion drawing.Findings reveal that, in aggregate, the learners’ mathematical critical-reasoning acuity resides at a middling tier, with 38% situated within the exceptionally high category, 48% classified as high, 7% occupying the moderate bracket, and 7% falling into the rudimentary level. Learners within the exceptionally high tier demonstrated the ability to articulate explanations with exactitude, adopt appropriate problem-solving stratagems, and procure accurate solutions. Conversely, those in the high category exhibited comprehension of algebraic notions yet were occasionally inattentive in executing procedural sequences. Students within the moderate classification manifested misjudgements in selecting suitable solution pathways, whereas those in the rudimentary group encountered impediments in deciphering essential information and constructing mathematical representations, often resorting to conjectural responses. The gender-oriented appraisal indicated the presence of stylistic and strategic discrepancies between male and female students in confronting problem-solving tasks, although such distinctions did not exert a substantive influence on their overall critical-reasoning competence. Broadly considered, this study accentuates the necessity of fortifying algebraic conceptualisation and sustaining systematic problem-solving practice as a means of enhancing learners’ critical-thinking aptitude.

Abstract

Higher Order Thinking Skills (HOTS) are essential competencies that students must possess. Many students still exhibit low levels of HOTS. This study aims to develop a Higher Order Thinking Skills (HOTS) instrument in comparison content for Phase D students. The research employed a development studies model consisting of two main stages: the preliminary stage and formative evaluation. The formative evaluation stage comprised several steps, including self-evaluation, expert review, one-to-one, small group, and field testing. The research subjects involved 30 Phase D students. Data were collected through validation sheets, student readability questionnaires, and HOTS test results, which were analyzed using Anates Uraian 4.0.5 software. The results indicated that the ten HOTS items developed met both rational and empirical validity criteria, showed very high reliability (0.95), had varying levels of difficulty (two easy, six moderate, and two difficult items), and demonstrated good discriminating power. Therefore, the developed HOTS instrument on comparison content is considered feasible to be used as an evaluation tool to enhance students’ critical, analytical, and creative thinking skills.

Abstract

This study aims to analyze students' mistakes in solving story problems in one-variable linear inequality material. Using a qualitative descriptive method, three grade VIII students of SMP Negeri 1 Kupang were selected as subjects based on the wrong answers in the description test. Data was obtained through written tests and interviews. The results of the study showed errors in understanding the context, estimating and interpreting variables, compiling mathematical models, and performing algebraic procedures. Students also misinterpret the final result so that the answers do not fit the real context. These findings show that students' mastery of algebraic concepts and mathematical modeling abilities is still low. A learning strategy that emphasizes understanding concepts and relating the material to contextual situations is needed to improve students' problem-solving skills.

Abstract

This study aims to develop a Problem Based Learning–based teaching module on the topic of Systems of Linear Equations and Inequalities to facilitate students’ mathematical problem-solving skills, with the criteria of validity and practicality. This research is a development study employing the 4D model, which consists of Define, Design, Develop, and Disseminate stages. The development process includes several stages: (1) Define, which involves front-end analysis, learner analysis, concept analysis, task analysis, and the specification of learning objectives; (2) Design, which includes the preparation of test standards, media selection, format determination, and initial design; (3) Develop, which comprises expert validation and development trials; and (4) Disseminate, which involves the dissemination of the product through seminars and publications. The instruments used in this study were expert validation sheets to assess the validity of the teaching module and student response questionnaires to measure the practicality of the student worksheets (LKPD). The results indicate that the teaching module is valid in several aspects and meets the criteria of being very valid after revisions based on validators’ suggestions. Furthermore, the implementation of the LKPD in the small group and field test stages demonstrates that the LKPD is very practical. This is evidenced by the fact that the LKPD is easy for students to understand.

Abstract

Statistics is often considered difficult by high school students because the learning approach tends to be theoretical and less interactive, resulting in students' low mathematical understanding of concepts such as mean, median, and mode. This study aims to develop educational website-based learning media with a Problem-Based Learning (PBL) approach to improve students' mathematical understanding. The research method uses the Research and Development (R&D) model with the adoption of the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. The research subjects were grade XI students of Imelda Private High School Medan who were divided into an experimental class (using PBL website media) and a control class (conventional method). Data were collected through validation sheets, student response questionnaires, and mathematical understanding tests (pre-test and post-test). The results of the website media were declared "Very Feasible" with a validation score of 95%. The effectiveness results showed a significant increase in the average post-test score (63.91) from the pre-test (26.26), with a Normalized Gain (N-Gain) score of 0.51 (category "Medium"). The student response questionnaire also showed a positive response, with an average of 82.57% ("Effective"). Implications This media, which has innovative features such as a statistical calculator and Excel upload data analysis, serves as an effective scaffold for PBL, encouraging students to conduct data analysis independently, and helping shift 73.9% of students from the "Very Low" ability category.

Abstract

The critical mathematical thinking skills of students in Indonesia are still very low. This is due to the learning process which only emphasizes conceptual understanding. This study aims to examine students’ mathematical critical thinking skills through the implementation of the Preprospec learning model assisted by Scratch with a STEM approach, based on findings from previous studies. The research employed a literature review method by analyzing relevant national and international journal articles related to the ICT-assisted Preprospec model, Scratch media, STEM approach, and mathematical critical thinking skills. The data used is secondary data from relevant previous research and was obtained through searches on Google Scholar. The analysis techniques used include content analysis and secondary analysis. The results indicate that the ICT-assisted Preprospec learning model consistently enhances students’ active participation and depth of thinking through Problem Solving and Evaluation stages. The use of Scratch has been shown to increase learning motivation and engagement, while the STEM approach effectively connects mathematical concepts to real-world contexts. The integration of these components contributes significantly to the improvement of students’ mathematical critical thinking skills, particularly in analyzing problems, evaluating solution strategies, and drawing logical conclusions.
