Abstract

Mathematical Modeling is the cornerstone and central aspect of the PISA framework. However, students still encounter difficulties in dealing with problems related to mathematical modeling. This study aims to produce a learning trajectory of mathematical modeling on functions material using the context of an online taxibike. Mathematical modeling activities on functions material are designed using the mathematical modeling cycle in the PISA framework. The subjects in this study were students of class X Bina Ilmi IT Senior High School Palembang. The research method used is validation studies. The research consisted of three stages, namely the preparation stage, the experimental design stage consisting of two cycles (cycle I: pilot experiment and cycle II: teaching experiment) and the retrospective analysis stage. Data was collected through observation, interviews and written test (students' work on the activity sheet and the results of pre-test and post-test). The results showed that learning activities that have been designed can assist students in solving mathematical modeling problems on functions. It begins with the formulate, employed, interprete/evaluate process. Through these mathematical modeling processes, students have a better understanding of functions and become accustomed to using mathematical modeling processes in solving contextual problems related to function material.

Abstract

This study investigated the effect of the multiple representations approaches on students’ representation interpretation in learning calculus. Pretest and posttest quasi-experimental design of non-equivalent groups was used. Three intact groups of size 53, 57, and 54 students from Jigjiga and Kebri-Dehar Universities in Ethiopia participated in this study. The groups included a GeoGebra-supported multiple representations approach (MRT) from Jigjiga University, a multiple representation approach (MR), and a conventional approach (CG), both from Kebri Dehar University. Representation interpretation problem pretest and posttest were administered compiled from pre and calculus contents, respectively. Students’ performance on representation interpretation problems was assessed using rubric scores, and their interpretation techniques were labeled as local versus global and syntactic versus semantic. Results revealed no statistically significant mean difference among the three groups on representation interpretation from the posttest that was determined by one-way ANOVA ((F(2.161) = 2.232, P = .111 , Partial eta = .03). More students in each group demonstrated local and semantic interpretation than global and syntactic interpretation. After the treatment, many students from each group shifted towards the local and semantic interpretation. It is recommended that the study need to replicate other calculus contents with different participants to generalize the results of the study.

Abstract

Teaching approach applied by mathematics teacher can affect students' mathematical connection ability (MCA). The fact shows that there are still many teachers using conventional learning, causing passive students and low MCA among students. The purpose of this study was to describe the effectiveness of applying a collaborative realistic mathematics education (RME) approach using the classroom and the outdoor environment to improve students' MCA on the topic of similar triangles. This quasi-experimental research with a qualitative descriptive approach took the subject of ninth-grade students at a public junior high school in Jember, Indonesia. Data were collected using observation sheets, questionnaires, tests, and interviews. The data were analyzed using the effectiveness test (N-gain score). The results showed that the application of collaborative RME using the indoor and outdoor classrooms made students more active in physical, social, and mental activities. This learning is effective in improving students' MCA. The average score of 57.47 in the pre-test increased to 93.88 in the post-test, and the N-gain score was 0.86. Mathematics teachers are advised to apply this learning approach, not only on the topic of similarity triangles, but also on other suitable topics.

Abstract

This research is aimed to design learning environment in which teacher can create a learning process in develop their reflective practices. Gending Sriwijaya traditional dance, which is familiar with culture in South Sumatera Indonesia, can be as a starting point for context in geometry translation. Applying The Indonesian Realistic Mathematics Learning Approach (PMRI) is one approach that uses contextual. The research used design research consisting of preparation of the experiment, design experiment and retrospective analysis. This research data were collected through classroom observation, documentation, interview, and field notes. The result of this research tries to establish that reflective teaching practice is a tool to makes room for teachers to critically examine any assumptions regarding acceptable objectives, methods, problems and solutions. By reflecting, conducting analysis, and coming to conclusions about what has occurred, the teacher might indirectly learn about the benefits and drawbacks of applying what they have learned. Collaborative learning supports and enhances learning by engaging groups which work together to solve problems, complete tasks, or learn new concepts. Students who have more ability help less-able students. On the other hand, less-able students ask for help from more-able students.

Abstract

Sometimes our smartphone's internal storage is complete, and we must download an application that is very necessary at that time; this is where numeracy plays a role in solving this problem, namely the way we download the desired application with a complete smartphone's internal storage. This study aims to produce valid and practical PISA-type questions and activities using a smartphone context and potentially effective on students' numeracy skills. This design research-type development study comprised a preliminary and formative evaluation phase consisting of the design stage, self-evaluation stage, expert review stage, one-to-one stage, and small group stage. This research used question grids, question cards, assessment rubrics, lesson plans, PISA-type questions, and student activity sheets as its tools. This study was initiated owing to the insufficient numeracy skills of Indonesian students. This study focuses on seventh-grade students at secondary school number 59 Palembang, Indonesia. The qualitative findings of this research are based on field data collected through walkthroughs, observations, tests, interviews, and document reviews. This research yielded PISA-type questions and activities, namely four activity questions and six evaluation questions with smartphone context that seventh graders may utilize to develop their numeracy abilities. In conclusion, PISA-type questions and activities in the context of smartphones can be used in classroom learning to strengthen students' numeracy skills.

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 research aims to develop a PISA-type content quantity that uses the context of religious holidays during the pandemic that is valid, practical, and potentially affects mathematical literacy skills. This research uses development research with two stages: preliminary and formative evaluation. This research also uses Inquiry-Based Learning (IBL) model in the learning process. This study involved eighth-grade students aged 13-15 years of various abilities. Data collection and analysis techniques were documentation, walkthroughs, observation, interviews, and tests. The research was carried out offline and online (Zoom and WhatsApp Group (WAG)). In this study, sharing activities were produced as well as a PISA-type jumping task with content quantity characteristics in the context of religious holiday during the pandemic by the PISA 2022 framework where what needs to be considered are mathematical literacy skills and use of language that is by language standards that can be applied and well interpreted by the students. Based on the students' answers, it can be seen that the questions and activities are included in the practical category because they can be solved well by students. From the results, it can be concluded that the developed PISA-like numeracy and activity has a potential effect on mathematical literacy skills and life in the context of religious days during the pandemic. In addition, IBL model can improve students' communication skills in solving PISA-type math problems and activities.

Abstract

The continuous exploration of mathematics as a human activity triggers the need to research ethnomathematics. This study aimed to identify ethnomathematics in the manufacture of indigenous fish traps (Bubu) from Bintan Regency. This ethnography study uses direct observation, interviews, and documentation. The researcher acts as the main instrument. The data were analyzed using the Spradley analysis technique, namely domain, taxonomic, componential, and cultural theme analysis. Data reduction, data presentation, and conclusions were carried out for each analysis. The results show that there are mathematical activities in designing, counting, and measuring length dimensions in Bubu's making. In these activities, there are mathematical concepts, including three-dimensional figures, the net of three-dimensional figures, curves, odd numbers, sequences with their attributes, bilateral symmetry, symmetry axes, figurative numbers, the congruence of plane figures, and length measurements with non-standardized units. These results showed that the Bubu maker already had a geometric sense through the symmetrical concept that became the basis for two activities such as counting and measuring, similar to the results of ethnomathematical research on the Yupiaq Eskimo community in Alaska and the Carolina Islanders in Micronesia. This study provides ideas to utilize everyday phenomena in teaching mathematics as a starting point prior to learning mathematics more formally.

Abstract

This study aims to investigate students’ prior knowledge as an obstacle when learning ratio and proportion concept. The study uses an interpretive paradigm which is part of Didactical Design Research. Eighth graders who had learned about ratio and proportion participated in this study. The analysis was carried out qualitatively based on the data from the students’ answers and interviews on their answers when solving ratio and proportion problems to identify learning obstacle, especially ontogenic obstacle regarding the students’ prior knowledge. The result of this study indicates that prior knowledge is one of the ontogenic obstacle in teaching and learning of ratio and proportion. It can be found from their learning experience in understanding the concept. In conclusion, investigating students' prior knowledge is essential for the effectiveness of teaching and learning of ratio and proportion. It is important to overcome ontogenic obstacles and to understand how to activate students’ prior knowledge using the right or appropriate methods when learning ratio and proportion.
