Abstract

There is a misconception about elementary school geometry material that makes the teacher's scientific attitude in implementing learning in the classroom still not optimal and causes the application of IT transformation to be uneven. This research aims to describe the misconceptions about geometry among elementary school teachers, the scientific attitudes of elementary school teachers in the process of learning geometry, and how elementary school teachers overcome misconceptions and optimize scientific attitudes learned from the role of IT. The subjects of this study were 171 teachers from 18 districts and cities. The research was conducted in a descriptive qualitative form by giving questionnaires about elementary school geometry concepts and teachers' scientific attitudes toward learning, analyzing answers according to criteria, and exploring the relationship between misconceptions and scientific attitudes learned from IT transformation. The results of this study indicate that conceptual errors were found in the research subjects, which included generalization and specialization misconceptions; the teacher's scientific attitude influences the misconceptions experienced; and the role of IT can help calculate and visualize abstract things in learning. The application of IT in the learning process shows good results for overcoming teachers' misconceptions and scientific attitudes, and of course, it can be an option for teachers to be able to apply it with various IT-based learning media that attract students' learning interests.

Abstract

The low ability of students to understand and transform the concept of reflection to solve everyday problems is the main problem with learning mathematics because the implementation of learning mathematics is mechanical. Mathematics is taught by conveying formulas practically without linking them to students' daily activities. For this reason, this study aims to design a reflection learning trajectory in the context of the Lipa Sabbe Bunga Caramming motif as a starting point in learning to help students understand reflection material for solving everyday problems. The method used in this study is design research, which consists of three stages: preliminary design, design trials, and retrospective analysis. The subjects of this study were 23 students in class VIII-A of SMP Negeri 1 Tanasitolo. The instruments used in this study were student activity sheets (LAS), learning achievement tests, and interview guidelines. Student activity data during learning were analyzed retrospectively, and learning outcomes data were analyzed descriptively. The results of this study found that the learning trajectory of transformation geometry using the context of the lipa sabbe bunga caramming motif has four learning stages: (1) informal; (2) modes of; (3) modes of; and (4) formal. The learning stages can easily increase students' understanding of the concept of reflection. In the learning process, mathematical concepts are connected with daily habits, so students are enthusiastic and active in the learning process. This learning trajectory can assist teachers in optimizing learning so that students can easily understand the concept of reflection, equip them with critical thinking skills, and shape their character (cooperation, empathy, respect for others, awareness of social problems, a social spirit, and responsibility).

Abstract

Preliminary research involving 30 mathematics teachers at the MGMP VHS of Ketapang district and interviews with business world and plantation industry representatives suggested that 81.7% of respondents voiced concerns over the current mathematics teaching materials, which do not adequately equip students with problem-solving skills in line with their expertise concentration. This issue reflects on the quality of VHS graduates who are expected to be job-ready and skilled. The objective of this study is to develop a measurable teaching module, conceptually and methodologically, that yields quantifiable results in alignment with the concentration of expertise and the requirements of the business and industry world. The research method adopted is a mixed method with a sequential explanatory design through the Van den Akker development study. A quantitative analysis of 20 respondents, comprising mathematics and productive teachers at a center of excellence vocational school, lecturers of Tanjung Pura STKIP, Ketapang State Polytechnic, and a team from the business and industry world in the plantation sector, resulted in a Pearson correlation of Ryx1x2x3=0.949, a determination coefficient [r2] of 0.900, and an F-calculation of 48.06 for the regression equation Y ̂ = 0.566 + 0.444 X1 + 0.278 X2 + 0.135 X3. From these results, it is concluded that the concepts, methods, and outcomes utilized in this teaching module are appropriate. The relationship between concepts, methods, and outcomes in teaching modules on skills to solve mathematical problems is unidirectional. Expert validity on aspects of module content, presentation feasibility, language appropriateness, and problem-solving skills amounted to 96.88% in the Very Valid category. Practicality from the aspects of interest, material, and language places the category at 92.02, which is very practical

Abstract

A discrepancy exists in students' mathematical critical thinking skills (MCTS) in mathematics classrooms implementing problem-based learning (PBL). The factor of school geographical location is predicted to affect the skill distinction of the students. This study aims to investigate and examine the school's geographical location assumed as a moderating factor of students' heterogeneous MCTS in PBL. Meta-analysis of 58 relevant documents containing 3,946 students and generating 59 effect sizes in the Hedges g unit was performed to conduct this study. Searching and selecting literature found 58 documents published from 2011 to 2021, consisting of 40 journal articles and 18 conference papers. Some tests, such as Q Cochrane and Z, were applied to analyze the data. The results showed that the school's geographical location was not a significant moderating factor that affected students' heterogeneous MCTS in PBL. In addition, PBL intervention significantly positively affected metropolitan, urban, and rural students' MCTS. Still, PBL intervention was more effective in the metropolitan area in enhancing students' MCTS than in urban or rural areas. This study suggests Indonesian government conduct the equable distribution of competent teachers and complete the facility and infrastructure of schools in each geographical location.

Abstract

Relational comprehension represents a critical skill that students should acquire to correctly associate concepts. This investigation aims to cultivate a High Order Thinking Skills (HOTS)-based Student Worksheet that is both valid and practical, as well as effective, with the potential to significantly influence the relational comprehension of senior high school students. The 'design research' method, incorporating a 'formative research' development model, is used in this research, which is broken down into two stages: initial assessment and self-review. This study was carried out at Muhammadiyah 1 High School in Palembang, focusing on tenth-grade students. Data was evaluated qualitatively in a descriptive manner, founded on observations, interviews, and tests. The study's findings highlight that the developed HOTS-based student worksheet is valid, practical, and efficient in boosting students' relational comprehension once implemented in the classroom. The test outcomes indicate that students possess a reasonably good ability to comprehend HOTS category C4 problems, but are lacking in understanding HOTS category C5 problems. Therefore, additional research is deemed necessary to enhance students' understanding of HOTS category C5 problems.

Abstract

The surface area and volume of cubes and cuboids are mathematical concepts related to everyday life. However, many students need help learning this concept. This study aims to analyze the learning obstacles junior high school students encounter when solving mathematical representation problems on the concept of surface area and volume of cubes and cuboids. This study uses an interpretive paradigm which is part of Didactical Design Research (DDR). Students at one of the public junior high schools in Jambi City were given six questions related to mathematical representation after the researchers conducted classroom observations, which were then followed by interviews with students with high, moderate, and low representation abilities. Data analysis techniques include data reduction, display, and conclusion drawing and verification. The results showed that students experienced three learning obstacles: ontogenic, epistemological, and didactical. Furthermore, the results of this study can be a consideration for teachers to create learning designs for surface area and volume of cubes and cuboids that can anticipate student learning obstacles and develop students' mathematical representation abilities.

Abstract

Mathematics textbooks that provide more descriptions of material and routine problems used so far cannot facilitate students in active learning activities. The lack of active students in learning activities causes creative thinking skills not to develop optimally. This paper aims to describe how problem-based learning textbooks can facilitate students in solving problems with different or varied solutions and even something new to foster creative thinking skills. This problem-based textbook has been developed and is one of the research products of IAIN Metro lecturers in 2021. This research is an experimental study consisting of experimental and control groups. Data collection techniques using tests and observations. The test data were analyzed using the mean difference test using the Mann-Whitney formula, while the observation data were analyzed using a descriptive qualitative approach. The findings of this study are constructive learning activities and open problems contained in problem-based learning textbooks significantly improve creative thinking skills. It is shown that the increase in creative thinking skills of students who study using problem-based learning textbooks is substantially higher than students who study using other textbooks. Thus, problem-based learning textbooks contribute to improving students' creative thinking skills.

Abstract

Background: Understanding the relationship between students' thinking styles and their numeracy literacy, especially in solving Higher Order Thinking Skills (HOTS) questions, is essential in educational research.Aim: This study aims to explore how students' thinking styles influence their numeracy literacy in addressing HOTS-based questions.Method: A descriptive qualitative approach was employed in this research. The study involved eight students from Larangan 1 Public Middle School, selected through a thinking style questionnaire. Two students were chosen from each of the four identified thinking style categories. Data were collected using tests comprising two HOTS-based questions and interviews.Results: The findings indicate that students' numeracy literacy varies significantly according to their thinking styles when solving HOTS questions. Students identified as SK and SA exhibited higher numeracy literacy, effectively utilizing various symbols and numbers, analyzing tabular information, and interpreting these analyses to make decisions. In contrast, students labeled as RK were only able to fulfill two numeracy literacy indicators and struggled with information analysis. RA students faced challenges in correctly writing numbers or symbols, analyzing information, and articulating problem-solving processes and conclusions. The study also found that students who process information sequentially exhibited better numeracy literacy in solving HOTS-based questions.Conclusion: The study concludes that students' thinking styles play a crucial role in their numeracy literacy, particularly in solving HOTS-based mathematical problems. This insight underscores the importance of considering individual cognitive styles in educational strategies to enhance mathematical problem-solving skills.
