Abstract

Metacognitive skills are a person's ability to control their thinking when planning, monitoring, and evaluating their cognitive processes. Students' metacognitive skills that appear when completing minimum competency assessment questions tend to be incomplete. In this case, students need the right strategies to solve these questions. Each student has different thinking processes and problem-solving strategies. One possible cause of this is different levels of mathematical ability. This research is a qualitative research with tests and interview methods that aim to describe students' metacognitive skills in solving AKM problems based on their level of mathematics ability. The subjects of this study were students with high, medium, and low mathematical abilities. Based on the study's results, all indicators of metacognitive skills, ie, planning, monitoring, and evaluation, appeared in subjects with high mathematics ability at every stage of problem solving. Meanwhile, some indicators do not appear completely for students with medium and low mathematics abilities. At the stage of carrying out the plan, the evaluation component was the indicator of metacognitive skills that did not appear in low-ability students. Meanwhile, for students with low mathematics ability, the indicators that did not appear were planning and monitoring in the stages of devising a plan and carrying out the plan.

Abstract

This study aims to describe the analogical reasoning of senior high school students with reflective and impulsive cognitive styles, particularly those with high mathematical ability, in solving open-ended problems. Analogical reasoning ability is important for students' success in understanding and solving mathematical problems. This study uses a qualitative approach with high school students selected based on their reflective and impulsive cognitive styles and high mathematical ability. Data were collected through the Matching Familiar Figure Test (MFFT) adapted from Warli, an analogy reasoning test using open-ended problems from SPLTV material, and interviews. Data analysis was based on analogy reasoning indicators, including the structuring, mapping, applying, and verifying stages. The results of the study indicate that reflective and impulsive students with high mathematical ability, both of whom are female, are able to perform all four stages of analogical reasoning well, identify problem elements, map similarities, apply strategies, and verify their work accurately.

Abstract

Algebraic thinking ability is an individual's ability to implement six types of mathematical thinking abilities, namely generalization, abstraction, analytical thinking, dynamic thinking, modeling, and organization. Algebraic thinking ability has a close relationship with problem-solving and cognitive style. This study aims to describe the algebraic thinking ability of junior high school students with cognitive style adaptation and innovation in solving math problems. This research used a descriptive qualitative approach. The research subjects selected were one student with an adaptation cognitive style and one with an innovation cognitive style, high mathematics ability, and the same gender. Researchers collected data using a cognitive style questionnaire, math ability, and problem-solving tests. The results showed that the ability of algebraic thinking of students with cognitive styles of adaptation and innovation in understanding the problem includes explaining the meaning of the problem with their language, identifying the problem by writing the information known and asked, and simplifying the information. In making plans, students can use abstract symbols, represent information coherently, tell pattern relationships mathematically, and find the pattern in question. In implementing the plan, students can use patterns to solve the problem, use intuitive methods, and identify the relationship between white and gray paving blocks. In re-examining, students review the steps of completion, ensure the correctness of the answer, and write conclusions. Students with cognitive styles of adaptation and innovation fulfill all indicators and show differences in working, but innovative students have not displayed a creative answer.

Abstract

Abstract: Technological advances in the 21st century have changed various aspects of human life, including education. One of the technological advances can be utilized as a scaffolding for students through YouTube videos. YouTube is the most frequently visited platform by internet users to learn about science. Scaffolding is assistance provided by more experienced people to others to be able to solve problems and reduce them gradually. Therefore, this study aims to explore YouTube videos as effective e-scaffolding in mathematics learning. This study uses a qualitative approach with an exploration type with thematic data analysis techniques. The data sources in this study are YouTube videos with the criteria of a minimum of 1000 viewers (views); (2) at least 50 comments; and at least 100 likes. The results of the study indicate that YouTube videos can assist students to understand and solve the problems given. E-scaffolding in this study is divided into two categories, namely local e-scaffolding and global e-scaffolding. Local e-scaffolding occurs when video content does not present arguments based on intrinsic mathematical properties, such as calculation tricks that are limited to a particular context. In contrast, global e-scaffolding provides assistance supported by arguments based on intrinsic mathematical principles, so that problem-solving strategies are more profound and generally valid.
