Abstract

This research aims to obtain students' mathematical reasoning abilities in solving sequence and arithmetic series word problems in terms of learning style. The method used is providing learning styles, written tests, interviews. The results of this research show that of the three visual, auditory and kinesthetic subjects the ones with the best mathematical reasoning abilities are the visual and kinesthetic learning style subjects. In conclusion, the mathematical reasoning ability of visual subjects is able to fulfill four indicators, namely representing ideas, determining solution strategies, implementing solution strategies, realizing solutions and interesting conclusions. The auditory subject's mathematical reasoning ability is able to fulfill four indicators, namely representing ideas, determining a solution strategy, implementing a solution strategy, solving a solution and drawing conclusions, but in the process there are errors so that the results obtained are less precise. Meanwhile, the mathematical reasoning ability of kinesthetic subjects is able to fulfill 3 indicators, namely representing ideas, determining completion strategies and implementing completion strategies. It's just that when drawing conclusions, kinesthetic subjects are unable to write down their conclusions. Keywords: Learning Style, Story Problems, Mathematical Reasoning Ability

Abstract

This study aims to describe the problem-solving profiles of eighth-grade students in the fraction material at SMPN Model Terpadu Madani, based on adversity quotient. The subjects of this study consist of 3 students selected based on the results of the ARP questionnaire and the recommendation of the mathematics teacher. The results of this study show that: (1) The problem-solving profile of students in the climber category can understand the problem by stating what is unknown and what data is given. However, they are less complete in writing down the known data from the problem, designing a well-structured solution plan, carrying out the plan as initially created, answering correctly, and checking their answer using a different method. (2) The problem-solving profile of students in the camper category can understand the problem by determining what is unknown and identifying the given data, designing a good and complete solution plan, carrying out the plan as initially made, and answering correctly, but they do not check their answer afterward. (3) The problem-solving profile of students in the quitter category can understand the problem by stating what is unknown and what data is given. However, they are less complete in writing down the known data from the problem, designing a good and complete solution plan, failing to implement the plan as initially made, not answering correctly, and not checking their answer afterward. In conclusion, there are 3 categories of students that require different treatment and attention from the teacher. Climber students need more attention in writing down the known data and checking their answer using a different method. Camper students need to be encouraged to check their answer after completing the problem, and quitter students require more intensive guidance in understanding the problem and carrying out the solution plan correctly. Keywords: Profile, Problem Solving, Fractions, Adversity Quotient.

Abstract

This study aims to describe students' mathematical reasoning ability in solving story problems of two-variable linear equation system. The method used is qualitative with a descriptive approach. The results showed that; (1) students with visual learning styles understood the information well through graphs, but were less thorough in numerical manipulation and verbal instructions, causing calculation errors and mathematical modeling (2) auditorial students were able to understand the problem and plan the solution well, but were less thorough in calculations and had difficulty transferring information to mathematical form, resulting in incorrect answers, (3) kinesthetic students understood the problem and planned the solution, but experienced errors in calculations due to difficulty understanding abstract information, lack of accuracy, and difficulty focusing for a long time. Therefore, it can be concluded that the reasoning ability of 8th grade students of SMPK BK Palu is quite good, it just needs to increase the accuracy of the students themselves.   Keywords: Mathematical Reasoning, SPLDV, Learning Style.

Abstract

This study aims to analyze students' errors in solving literacy and numeracy problems based on Kastolan's stages and to identify the factors that contribute to these errors in order to minimize them during the learning process. This research employs a qualitative method with a study case. The subjects selected were six students out of a total of 36 students in class X-2 at SMAN 94 Jakarta. The results of the study indicate that the level of students’ literacy and numeracy skills influences the types and frequency of errors made. The conclusion reveals the factors behind each type of error: (1) conceptual errors occur due to a lack of understanding of the material and basic concepts, which leads students to choose incorrect formulas; (2) procedural errors arise from students’ inability to organize the steps of problem-solving in a sequential and systematic manner; and (3) technical errors result from inaccuracy in modeling the problem into mathematical form, such as writing incorrect variables or numbers.   Keywords: Erros Analysis, Kastolan Stages, Literacy and Numeracy Issues
