Abstract

The ability to solve students' mathematical problems cannot be diagnosed clearly just by using test questions; it must also be seen by looking at students' responses to the problem-solving process. As a result, the purpose of this study is to investigate students' mathematical problem-solving skill as well as their responses to the problem-solving process. This study is descriptive-qualitative in nature. Three junior high schools (SMP) in Aceh participated in this study, with 76 class VIII students serving as research subjects. Tests, observations, and interviews were used as data collection techniques. Quantitative data were descriptively analyzed using proportions, while qualitative data were descriptively analyzed using coding. The results showed that 25 percent of students wrote down what was known and asked, which was an indication of problem comprehension; 21 percent of students were able to devise problem-solving strategies; and 15 percent of students had done calculations correctly. correct, 11 percent of students checked their answers again. Based on the responses given by students, there were some difficulties experienced by students when solving math problems, namely difficulty understanding reading texts, using mathematical terms, making problem connections, making decisions, uncertainty in solving problems, time, carelessness, and boredom. The findings of this study are expected to serve as a resource for teachers and education practitioners in developing focus, discipline, and patience in problem solving and selecting learning models appropriate to the needs of their students.

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

Studies on the effectiveness of STEM implementation in Mathematics learning, especially in mathematical creative thinking ability carried out by previous researchers, are interesting to be studied. However, several studies have shown different results that can lead to different interpretations. This study aims to estimate dan examine the effectiveness of STEM on students' mathematical creative thinking ability from the relevant studies. This study analyzed 12 primary studies from various electronic search engines within the year of publication from 2017 to 2022. All primary studies in this research were analyzed using the meta-analysis with Comprehensive Meta-Analysis 3.0 (CMA 3.0) software by selecting the formula of Hedge to determine its effect size. The results of this meta-analysis study indicated that the STEM approach was effective for students' mathematical creative thinking abilities with an effect size of 0,935 in the category of high effect. There were differences in the effect size of the STEM approach on students' mathematical creative thinking abilities regarding STEM integration with learning models and educational levels. This means that the type of integration of the STEM approach with the learning model and educational level significantly causes heterogeneity in students' mathematical creative thinking abilities. The results of this study are expected to provide educators with an overview of how STEM can be applied in mathematics learning, especially in improving mathematical creative thinking ability.

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

Geogebra is a mathematical software that can be used in mathematics, especially geometry, calculus, and dynamic algebra, with various features, especially visualization. Geogebra helps students identify and improve their visual skills in understanding mathematical concepts. This study aims to explore the mathematical technology knowledge of teachers based on Geo-Gebra applications in mathematics learning by integrating content and technology. This research is qualitative research that uses a single-case design to explore the teacher's mathematical technology knowledge and involved teachers (N = 8) from the field of mathematics at universities in the Central Region of Indonesia. Three types of data were collected during one semester, weekly observations, progress report description; and the developed learning design. This research shows that there are two categories of teachers' mathematical technology knowledge characteristics. First, moderate teachers produce simple designs and are still influ-enced by numerical and algebraic approaches. Second, expert teachers can use analytical skills to design step-by-step learning, involving animation to explain concepts, and the resulting designs are quite complex and structured. These two findings are useful for building teacher competencies regarding using GeoGebra ap-plication-based technology in learning mathematics.
