Abstract

This study addresses the challenges faced by students in comprehending and articulating the concepts of cost, selling price, and profit, despite their ability to perform related calculations. Contributing factors include a limited learning context and a didactic approach that often prioritizes rote memorization of formulas, thereby hindering a deeper understanding of these concepts. The objective of this research is to design a learning trajectory utilizing the context of New Pempek Mathematics, an innovative adaptation of the traditional Pempek dish, represented in geometric forms such as cones, trapezoidal prisms, cuboids, and cubes, to facilitate students' understanding of cost price, selling price, and profit. The study employs a design research methodology, consisting of three stages: preliminary design, experimental design, and retrospective analysis. The study involved 31 junior high school students from Belitang, Indonesia. Data collection was conducted using a variety of instruments, including student worksheets, video recordings of lessons, interviews with students, and photographs of their presentation work. The proposed learning trajectory, centered around the New Pempek Mathematics production project, emphasizes activities such as identifying cost prices, estimating selling prices, and calculating profit. The findings indicate that integrating mathematics with local cultural contexts, such as New Pempek Mathematics, enhances student engagement and makes the learning experience more relevant, thus improving students' understanding of these fundamental economic concepts.

Abstract

One of indicators to determine the quality of a journal can be observed from how many indexing institutions recognized it nationally and globally, such as Sinta, Scopus, and ScimagoJR. Furthermore, the rank of a journal in the indexing institution will add more value to the reputation of a journal. However, few journal editors are willing to share their experiences in managing a journal, from the beginning to getting recognition at the international level. Thus, this article describes the journey of the first journal in the mathematics education field from Indonesia called the Journal on Mathematics Education (JME), which is globally recognized and indexed on Scopus. JME's journey to gain global recognition is narrated in a structured way, starting from the history of journal formation, recognition at the local level, strategies to get authors from various countries, promotional activities to get credit, until finally getting a global position. In addition, this article also describes many contributions from world-class Mathematics Education researchers who have published their research results in JME. Finally, this article also describes the position of JME at national and international levels based on the data of several indexing institutes and JME's future targets.

Abstract

This research aims to describe students' cognitive processes in understanding fractions through a tourist context. This research method is design research. The data collection technique is through tests and in-depth interviews. The results of this research show that student's cognitive process in understanding fractions through a tourism context is that students first understand the problems in the tourism context of Lake Air Gegas; then students create mathematical models based on context; third, students complete mathematical models based on context; the fourth student creates a solution to the context problem; Finally, students make mathematical conclusions. Through the tourism context, students can solve problems appropriately. The conclusion is that there are five stages of students' cognitive process in discovering the principle of multiplication of fractions, namely students understand the problem through a tourism context, create a mathematical model based on context, complete a mathematical model based on context, create a context problem solution, and end by making mathematical conclusions about the principle of Multiplication of Fractions. Therefore, it is recommended that mathematics teachers use the tourism context as a starting point for mathematics learning.

Abstract

Fraction division is considered one of the most difficult concepts in learning fractions. This study aims to investigate students’ understanding of fraction division through a partition division conceptualization, utilizing their understanding of fractions as parts of a whole. To achieve this, we designed a hypothetical learning trajectory, in which students engaged with incomplete partition task. This article reports on a two-week design research intervention involving 21 fifth-grade students. The students’ written works, transcripts of teaching experiment recordings, and observational notes were retrospectively analyzed to examine the hypothetical learning trajectory. The study revealed that the students’ primary challenge was recognizing the correct whole during the teaching experiment. This study suggests that incorporating a stronger focus on proportional reasoning and varying fraction sizes in instructional approaches may help address this obstacle.
