Abstract

Heuristic strategy is one of the mathematics problem solving strategies to gain effective results. This research aimed to analyze the use of the heuristic strategies based on the modification of the Krulik and Rudnik model. This research discovered and classified the students' heuristic strategies which can be used as a basis to provide assistance in the learning. This research was a qualitative research involving 32 students of SMP Muhammadiyah 4 Yogyakarta as its subjects. The research variables are the indicators of the Krulik and Rudnik heuristic models which the students performed including: read and think, explore and plan, select a strategy, find and answer, as well as reflect and extend. The data was taken through questionnaire and interview methods. The result suggested that: 2 students (6.25%) were in the good category as they did all of the heuristic strategies more often; 21 students (65.62%) were in the fair category since they implemented some indicators of the heuristic strategies; and 9 students (28.13%) were in the poor category since they were lack in implementing the heuristic strategies. In all categories, indicator of find and answer was more oftenly done by the students while the indicator of explore and plan was less done.

Abstract

Environmental sustainability is a crucial concern for universities due to the environmental impacts of their operations, including energy use, waste, and transportation. As key actors, higher education institutions play a vital role in promoting sustainability by enhancing students' knowledge, attitudes, and active participation in sustainable practices. This study aims to analyze the relationship between environmental education, knowledge, attitude, and behavior. A total of 376 students of Universitas Negeri Semarang were involved in this study. Data were collected through questionnaires distributed online. Data analysis was carried out using the PLS-SEM analysis technique. The results showed that environmental attitude has a positive effect on student environmental behavior. However, environmental education and knowledge were not proven to significantly influence environmental behavior directly. Environmental education has been shown to play an important role in significantly increasing knowledge and attitudes towards the environment. In addition, environmental education can indirectly influence environmental behavior through the formation of environmental attitudes. The implication of this study shows that the universities and higher education policymakers need to emphasize strengthening positive attitudes toward the environment in environmental education curricula, rather than just focusing on increasing knowledge alone.

Abstract

This research aims to identify and analyze students' critical thinking skills and learning barriers in learning mathematics translation material. The concept of translation is fundamental for students who want to master geometric transformations. Students must understand the basics of translation because this understanding of translation will be needed at a higher level. However, many students still experience obstacles in understanding translation material. Students experience learning impediments because of the difference between the expected achievements of critical thinking skill indicators, interpretation, analysis, evaluation, and inference, and the actual results. This research uses a qualitative descriptive research methodology, utilizing data collection techniques such as interviews, observation, and documentation. Data analysis was conducted using descriptive methods with 30 class XI-1 students as participants. Triangulation was used in the data collection process, which involved using teacher and student interviews, administering diagnostic tests, and textbook analysis (document analysis). The research results show that the average percentage of students' critical thinking abilities from the four indicators is 41.665%. Ontogenic, didactic, and epistemological barriers cause the low critical thinking skills of class XI-1 in studying translation. The research results can be used as considerations for teachers in designing learning to improve critical thinking skills and reduce students' learning barriers in learning translational material.

Abstract

Dynamic thinking is a crucial cognitive skill that enables students to solve complex problems in geometry effectively. This study investigates the characteristics of dynamic thinking among prospective mathematics teachers, focusing on the four key aspects: technique, conceptualization, monitoring, and perception. While previous research has identified these aspects, the specific problem-solving characteristics of dynamic thinking in mathematical contexts remain unexplored. This qualitative study was conducted at Tidar University, involving 54 prospective mathematics teachers identified as dynamic thinkers. Data were collected through a two-stage problem-solving test, structured observations, and in-depth interviews. The research instruments underwent a validation process to ensure reliability. Data analysis followed a systematic approach involving reduction, presentation, and verification to extract patterns of dynamic thinking among proficient problem solvers. The results indicate that students who exhibit proficient dynamic thinking demonstrate completeness and consistency in all four aspects. They effectively integrate multiple strategies, adapt their approaches in response to challenges, and maintain a reflective understanding of their problem-solving processes. Additionally, proficient dynamic thinkers show a higher degree of flexibility and spatial reasoning in geometry problems. This study contributes to the existing body of knowledge by identifying and describing the specific characteristics of dynamic thinking in mathematical problem-solving. The findings provide valuable insights for teacher education programs, emphasizing the need to cultivate dynamic thinking skills among prospective math educators. Future research can explore dynamic thinking across different mathematical domains and cognitive frameworks.
