Abstract

Mathematical problem-solving ability is a directed thinking process that students do to solve mathematical problems. This study aims to describe the mathematical problem-solving abilities of tenth-grade students at SMAIT Anak Sholeh on the topic of sequences and series, viewed from their initial ability levels (high, medium, and low). A descriptive qualitative research method was employed. Data were collected through written tests to measure initial and problem-solving abilities, and interviews to confirm student responses. The data analysis focused on the four problem-solving stages according to Polya: understanding the problem, devising a plan, carrying out the plan, and looking back. The results show a relationship between initial ability and mathematical problem-solving ability. It was found that students with high initial ability tend to have high problem-solving skills, enabling them to master all four of Polya's stages well. Students with medium ability generally faced obstacles at the planning stage, such as selecting incorrect strategies or formulas. Meanwhile, students with low ability exhibited weaknesses at every Polya's stages, starting from a poor ability to understand the problem through to re-checking the results. This study concludes that initial ability influences every stage of a student's mathematical problem-solving process, making the strengthening of initial ability an important factor to be considered for improving the quality of mathematics learning ability and students' problem-solving skills.

Abstract

This study aims to improve the learning outcomes of sixth-grade students on the topic of ratio equivalence through the implementation of the Problem-Based Learning (PBL) model with a scientific approach. The research employed a Classroom Action Research (CAR) design conducted in two cycles. Data were collected through student activity observations and learning outcome tests, covering the cognitive, affective, and psychomotor domains. The results showed a significant improvement in all three aspects. Student activity reached the "very active" category, and student achievement in all domains exceeded the minimum classical mastery criteria. These findings indicate that the PBL model based on a scientific approach is effective in mathematics instruction to comprehensively enhance student learning outcomes.

Abstract

One of the objectives of mathematics learning is to equip students with problem-solving skills. Each student has different abilities in solving problems, and one of the influencing factors is personality. This study aims to describe students' mathematical problem-solving abilities based on the APOS theory (Action, Process, Object, Schema) in terms of David Keirsey's personality types among eighth-grade students at MTs Negeri 1 Lombok Timur in the 2024/2025 academic year. This research uses a qualitative approach with purposive sampling as the technique for determining research subjects. Data collection was carried out through questionnaires, tests, interviews, and documentation. The results showed that the guardian-type subject was only able to complete 3 out of 4 APOS stages: action, process, and object. The artisan-type subject was only able to complete 2 out of 4 APOS stages: action and process. The rational-type subject was able to complete all APOS stages: action, process, object, and schema. The idealist-type subject was also able to complete all APOS stages: action, process, object, and schema. Thus, it can be concluded that subjects with rational and idealist personality types have better problem-solving abilities than those with guardian and artisan personality types.

Abstract

Story problems are problems related to real life that contain a problem to be solved. Solving story problems requires the ability to understand the content of the problem. However, many students still experience difficulties in solving story problems. The purpose of this study is to describe the types of errors and their causes among students with visual, auditory, and kinesthetic learning styles in the Pythagorean theorem material. Error analysis was conducted based on Newman's procedure. The subjects of this study were student in class VIII-1 of SMPN 3 Mataram for the 2024/2025 academic year, selected using purposive sampling. The data collection techniques used were questionnaires, story problem tests, and interviews. The data analysis techniques used were data reduction, data presentation, and drawing conclusions. The results of the study revealed: (i) students with a visual learning style made errors in problem transformation and writing conclusions. The causes of errors made by visual learners include being careless in determining formulas, incorrectly illustrating known information, mistakenly determining formulas, not knowing the steps to solve the problem, and errors in previous stages. (ii) Students with an auditory learning style made errors in problem transformation, process skills, and writing conclusions. The causes of errors made by auditory learners include being careless in performing calculations, confusion in determining formulas, and errors in previous stages. (iii) Students with a kinesthetic learning style make errors in problem transformation, process skills, and writing conclusions. The causes of errors made by kinesthetic learners include incorrectly illustrating information, not knowing how to solve problems, answering arbitrarily, and errors in the calculation process.

Abstract

Science is a branch of science that is factual, either in the form of facts or events that are interconnected by cause and effect. Science was initially obtained through experiments (inductive) but over time, it was also developed with theory (deductive). Science in schools aims to ensure that students understand the processes and products of science, have a scientific attitude, and are able to become ethical citizens who are sensitive to environmental issues. The word "Alat Peraga" comes from two words, namely "alat" and "peraga". The main word in this term is "peraga", which functions to "demonstrate" or form a physical representation of a concept or understanding being explained. This physical form can be a real object, an imitation object such as a model, or a visual/audiovisual image. Science literacy (LS) comes from a combination of two Latin words, namely literatus, which means literate or educated, and scientia, which means knowledge. Scientific literacy is a person's ability to understand, communicate (both verbally and in writing), and apply scientific knowledge to solve problems, so that a person can develop a high attitude and sensitivity towards themselves and the environment in making decisions based on scientific considerations.
