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.

Abstract

The existence of a Student Worksheet (LKPD) is able to improve the ability to understand students' concepts. This research aims to develop LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the ability to understand concepts based on validity, practicality, and effectiveness in geometric transformation materials. The type of research used is research and development (R&D) with a 4D model, namely the defining stage, the design stage, the development stage, and the deployment stage. This study was conducted at SMP Negeri 1 Tegalrejo with a sample of 31 students in class IX B. The results showed that an LKPD based on ethnomathematics of batik motifs typical of Magelang was produced to increase understanding of the concept of geometric transformation that is valid or feasible in terms of the validity value of LKPD by material expert validators and teaching material expert validators, which is 86.31% with a very valid category. Judging from the practicality value of LKPD by the response of students, which is 89.61% with a very practical category. The results of the standard gain increased concept understanding ability were obtained by 5 low classification learners, 10 medium classification students, and 16 high classification students. Increasing understanding of the concept of geometric transformation using LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the effectiveness value of the pretest and posttest results calculated using the standard gain formula <g> , which is 0.62 with a moderate category, so that LKPD is said to be effective.

Abstract

As many as 7.03% of people with disabilities in Indonesia are deaf people. The problem for deaf students is the lack of mathematics learning resources during learning and the low mathematical communication skills of deaf students. The purpose of this study is to analyze the development of sign language learning videos to improve mathematical communication of deaf students of fractional material in terms of validity, practicality, and effectiveness. The method used is the R&D method with a 4D model. The results showed that the validity of the media resulted in a very valid category by sign language experts with a score of 85% and material experts with a score of 83% and categories valid by media experts with a score of 78.5%. The results of media practicality of 100% for teacher and student responses and learning implementation questionnaires are said to be very practical. The results of the control class pretest and the experiment resulted in a sig value. > 0.05, then the data is normal. Homogeneity test with (6,14) <  (19) on pretest questions and (4,68) <  (19) on posttest questions then homogeneous data. Student scores resulted in a difference in the average student learning outcomes between the experimental class and the control class indicated by the T test results with the sig value. (0.001) < 0.05. The average value of the N Gain of the experimental class is greater than that of the control class, which is 0.9721 with a high category. so that the media is said to be valid, practical, and effective.

Abstract

The development of students’ Complex Problem Solving (CPS) skills remains constrained by mathematics instruction that is primarily procedural and insufficiently connected to real-world global issues, particularly climate change. To address this limitation, the present study investigates whether STEM learning supported by Dynamic Mathematics Software (DMS) can improve senior high school students’ CPS abilities within climate change contexts. A quasi-experimental, non-equivalent pretest–posttest control group design was implemented with 69 eleventh-grade students. The experimental group participated in STEM learning integrated with DMS, while the control group received direct instruction on the same climate change context. Data were analyzed using descriptive statistics, Wilcoxon signed-rank tests, paired-sample t-tests, N-Gain, and Cohen’s D. Results showed that the experimental group achieved a high N-gain score (0.79), whereas the control group attained a low gain (0.29). The magnitude of this increase is also reflected in the effect size Cohen's d values, 5.893 in the experimental class and 2.438 in the control class. These findings suggest that STEM learning supported by Dynamic Mathematics Software constitutes an effective pedagogical strategy for advancing students’ complex problem-solving skills and strengthening mathematics education

Abstract

Matematika dan budaya adalah dua hal yang sangat erat kaitannya. Namun terkadang matematika dipandang sebagai sesuatu yang tidak berhubungan dengan kehidupan sehari-hari. Infactthe environment dapat menjadi sumber permasalahan matematika dalam kehidupan nyata. Lingkungan merupakan salah satu budaya yang salah satunya termasuk bangunan bersejarah. Matematika dalam budaya disebut dengan istilah ethnomatematics. Lawang Sewu merupakan salah satu bangunan bersejarah yang terletak di kota Semarang. Tujuan dari penelitian ini adalah untuk mengetahui struktur geometri gedung Lawang Sewu. Gedung ini dapat digunakan sebagai objek penelitian dengan metode deskriptif kualitatif, dengan pengumpulan data menggunakan observasi langsung terhadap objek penelitian, wawancara dengan narasumber, dan menggunakan studi pustaka terkait dengan penelitian ini. Melalui penelitian yang penulis lakukan, dapat disimpulkan bahwa bangunan Lawang Sewu memiliki struktur geometri ruang yaitu kubus, balok, limas, dan prisma segi delapan. Mathematics and culture are two things closely related. But sometimes mathematics is seen as something that is not connected to everyday life. Infactthe environment can be a source of mathematical problems in real life. The environment is one of culture, one of which includes historic buildings. Mathematics in culture is referred to by the term ethnomatematics. Lawang Sewu is one of the historical buildings located in the city of Semarang. The purpose of this research is to know the geometry structure of Lawang Sewu building. This building can be used as a research object with qualitative descriptive method, with data collection using direct observation on research object, interview with speaker, and using library study related to research This. Through research that the authors have done, it can be concluded that Lawang Sewu building has a geometry structure of space, namely cube, beam, limas, and octagonal prism.
