Abstract

The essence of the independent curriculum and Pancasila student profile requires teachers to adapt teaching materials to the PISA framework and invite students to think critically. For this reason, this qualitative descriptive research aimed to describe students' critical thinking skills in solving mathematical PISA-like questions on the quantity content in the context of the Jakabaring Palembang tourism using the Indonesian Realistic Mathematics Education (PMRI in Bahasa) approach. This research involved 36 under-15 students of a junior high school in Palembang. Data from observations, tests, and interviews were collected and analyzed qualitatively to measure students' critical thinking skills. The results of this study indicated that the students' critical thinking ability belonged to the moderate category, with a total of 22 students in this category. The highest scoring critical thinking indicator was interpretation (86.1%), while the lowest was analysis (13.8%). The former was dominant in students because when learning using the PMRI approach, students could model problems into their interpretations. Solving PISA-like questions could train students to develop the interpretation indicator of critical thinking skills and at the same time introduce the Palembang Jakabaring tourism.

Abstract

This study focused on developing student worksheet (SW) based on philosophy on the topic of matrix operations, including an overview of its effect on students' conceptual understanding abilities of grade XI at Senior High School (SMA in Bahasa) IT Bina Ilmi Palembang. It discussed how the student worksheet produced could be valid, practical, and had potential effects. The method used was development research consisting of preliminary, prototyping and assessment phase stages. This student worksheet consisted of the history of the matrix (ontology), matrix operation procedures (epistemology) and implementation of the matrix (axiology). The results showed that the validity of the student worksheet amounted to 84.1% with a valid category and could be used with minor revisions. The practicality score at the small group stage was 87.8% with a very practical category. Statistical results showed that there was an increase in the average score of a significant test result of 59.06. This showed that there was a positive effect from the use of philosophy-based SW on students' conceptual understanding. Based on these results, the philosophy-based student worksheet developed was categorized as valid, practical, and effective in improving students' conceptual understanding ability on matrix material.

Abstract

Rotation is an essential part of geometric transformations. This research aims to produce a learning trajectory of rotation material and determine the role of activities in learning the rotation which is expected to be able to support students understanding the concept of rotation learning in grade IX. The approach used is Pendidikan Matematika Realistik Indonesia (PMRI) with Lesson Study for Learning Community (LSLC) as learning system. The method used in this research is a design research type validation study. This research was conducted in limited face-to-fece meetings at secondary school number 1 Palembang during the pandemic and involved 13 students of class IX. The data were collected using video recordings and photos taken during the learning process, student interviews, student work, discussion results, and field notes at each meeting. The results of this study indicate that the learning trajectory can support the informal to formal concept of rotation, including the activity of recording the starting point and endpoint, analyzing and interpreting changes of starting and endpoints using one’s language, and writing the rotation formula. Therefore, it can be concluded that a series of activities by exploring the Palembang songket fabric motif plays a role in helping students understand the concept of rotation easily and allows them to produce rational imaginations and fun learning.

Abstract

This research aims to examine a) what computational thinking indicators have been developed by researchers, b) what computational thinking indicators can be used in learning mathematics appropriately, and c) how to describe the development of student computational thinking indicators from the answers of computational thinking tests. This research is a qualitative descriptive study through a process of collecting data from literature reviews, integrated computational thinking math tests, and interviews. Data collection instruments used research notes, interview sheets, and CT question sheets. The results showed that a) 20 computational thinking indicators had been studied by researchers, b) computational thinking indicators that could be used in learning mathematics include problem decomposition, abstraction, pattern recognition, procedural algorithms, and generalizations, and c) From the student answers, five proposed computational thinking indicators can be developed even though they were not perfect. The general implication of this research is that there are five indicators of computational thinking skills that can be used in mathematics learning, specifically in number patterns, which include problem decomposition, abstraction, pattern recognition, pattern recognition, procedural algorithm, and generalization. The researchers developed all five computational thinking skills indicators in the instructional designs of not only the number pattern concept but also combination, geometry, combinatorics, etc.

Abstract

Islamic contexts help stimulate students' mathematical abilities and develop their religious thinking. Therefore, this research aims to describe students' thinking process in solving mathematical literacy problems adapted from PISA questions using Islamic contexts. This research is qualitative-descriptive in nature with the purposive sampling technique used to select the three best teams competing on the National Mathematics Olympiad organized by the Mathematics Education Study Program of UIN Syarif Hidayatullah Jakarta in 2018. Each school level (Islamic elementary school (MI), Islamic junior high school (MTs), and Islamic senior high school (MA)) was represented by a team of 3 students. Data were collected through tests of mathematical literacy in Islamic contexts that matched PISA contexts and through interviews. Then, the data collected were analysed using triangulation techniques. The results showed that the students' thinking process in solving mathematical literacy problems in Islamic contexts was in accordance with Bayer’s thinking process theory. In general, the students already engaged in a thought process starting from information processing to decision-making. In fact, some MTs students had reached the thinking level of analysing relationships, synthesising problems or arguments, and conducting evaluations using several criteria suitable for the MA level. So it can be concluded that he Islamic contexts used in mathematical literacy questions tend to draw students' attention to the problems and help them solve those problems.

Abstract

The aim of this research was to determine the spatial reasoning constructs employed by pre-service elementary school teachers when solving geometry problems. A total of 36 participants were invited to complete an online test, after which two selected individuals were engaged in solving the problems. Interviews were then conducted to accurately describe the process of solving geometric problems. The results showed the existence of two types of spatial reasoning constructions, namely series and parallel. Both construction types revealed the interrelationship between spatial reasoning and the problem-solving process. This research highlighted the significance of spatial reasoning as an integral component in solving geometric problems, emphasizing the need for further investigation into its distinctiveness. This could be achieved by incorporating advanced geometric concepts and materials into future research.

Abstract

Statistical literacy is an essential competence that people must face in the era of big data and Society 5.0. In Indonesia and several countries, statistics is taught as a list of competencies in mathematics subject in primary and secondary schools. This study aimed to identify whether statistical tasks in higher secondary school mathematics textbooks support statistical literacy. The qualitative data were collected via deductive content analysis, with a specific framework, toward five Compulsory Mathematics textbooks used in Indonesia. We found that statistical exercises and problems in these textbooks were dominated by data analysis type, emphasizing calculating statistics from raw data and its modification. Regarding data visualization, almost all textbooks introduced the histogram and ogive, while some also introduced the boxplot, stem-and-leaf plot, and dot plot. Improvement could be made by adding more exercises and problems related to the interpretation of statistics, evaluation of statistical results, and comparison of statistics from several data groups.
