Abstract

There are still many learners who have difficulty in coordinate system material. Efforts to overcome the difficulties of students in mathematics lessons coordinate system material, one of which is the use of learning media. One of the media that can be used in learning in the current era is interactive learning media. However, there are many obstacles experienced by teachers in making interactive learning media. Currently, interactive learning media is needed that allows students to learn material that can be accessed by students anywhere independently and without teacher assistance. Educational games can be developed in the form of applications that run using smartphones to make them more practical and easy to use by students. But more students use smartphones just for fun, such as playing games that have nothing to do with learning. In order for a smartphone to be used, an operating system such as Android is needed. Based on the description above, a new and easy to work Android-based educational game is needed, so researchers chose Articulate Storyline software to create an Android-based educational game. Related to what has been described above, researchers developed an Android-based educational game with Articulate Storyline on the Coordinate System material. This study aims to describe the process of developing Android-based educational games with Articulate Storyline on Coordinate System material and describe the results of developing Android-based educational games with Articulate Storyline on valid, practical, and effective Coordinate System material. The method used in this research is development research (Reasearch and Development). The development model used in this research is the ADDIE model which includes Analysis, Design, Development, Implementation, and Evaluation. Validity instruments in the form of validation questionnaires, practical instruments in the form of student response questionnaires, and effectiveness instruments carried out pre-test and post-test. This Android-based educational game is implemented for students of grade VIII J SMPN 26 Surabaya. The results showed that, this educational game obtained a validity percentage value of 90.25% so that it can be categorized as very valid. Educational games are said to be practical because the results obtained from the student response questionnaire obtain a percentage value 89,425 % so it is categorized as very practical. The results of using this educational game are also effective because the N-gain results obtained are 0.92505847 which is in the high category.

Abstract

The Hypothetical Learning Trajectory (HLT) has a role in constructing potential learning paths for students based on their thinking. It includes learning objectives, learning activities, and learning hypotheses to help students reach the desired endpoint. Therefore, this research aims to produce a learning trajectory for algebraic multiplication using the Realistic Mathematics Education (RME) approach. The method used is design research, consisting of three stages: Preparing for the Experiment, Design Experiment, and Retrospective Analysis. The HLT design was tested on 6 participants selected based on the lowest scores on a pre-test. This research was conducted up to the pilot experiment stage with five activities aimed at learning objectives, including the multiplication of forms or for activity 1, the multiplication of forms for activity 2, the multiplication of forms or for activity 3, the multiplication of forms or for activity 4, and the multiplication of forms for activity 5. Video recordings, field notes, documentation of student work, and pre-test and post-test data were collected in this study. The results of this study indicate that HLT design 1, which emerged from the design implementation, can help students learn algebraic multiplication. Meaningful contexts for students, combined with questions posed by the teacher, encourage students to think about the mathematical ideas discussed, thereby generating different strategies for solving given problems.

Abstract

Proportional reasoning has been greatly influencing the development of students’ mathematical abilities. Along with the area conservation ability, it helps elementary students comprehend area measurement. This exploratory study aimed to produce qualitative-descriptive data on elementary students’ proportional reasoning in solving the conservation of plane figures. The study used guided-unguided area conservation problems using a proportional reasoning level as the analysis framework. Data were collected from 4 primary school students in Sidoarjo, Indonesia, who were in fifth-grade class. The students' strategies used were identified to analyze the students' proportional reasoning in solving area conservation. Results show that the level of proportional reasoning varies from zero to two. Regarding the students' proportional reasoning levels, most of the students' strategies use visual clues and cute paste strategies. Only one student can reach the level of quantitative reasoning by using a formula to compare both area measurements. Interestingly, the problem of the conservation of plane figures failed to reveal students' formal proportional reasoning due to their insufficient knowledge of fractions, division, multiplication, and decimals. Some implications regarding students' proportional reasoning and interventions in the area conservation problem are discussed.

Abstract

Nutrition facts are the details on food packaging that describe its nutritional value, including serving size, calories, macronutrients like carbohydrates, protein, and fat, and micronutrients such as vitamins and minerals. These facts have mathematical concepts that can be utilized as a context for prospective teachers to create mathematical problems. By leveraging this real-world data, educators can contribute to multiple Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being), by promoting nutritional awareness, and SDG 4 (Quality Education) by enhancing student engagement and understanding through relatable examples. This study examines the profile of mathematical tasks created by prospective mathematics teachers using nutrition facts as a context that meets numeracy task criteria. Data were collected from 62 mathematical tasks created by 31 prospective teachers attending a realistic mathematics education course on numeracy based on a problem-posing task at a public university in Surabaya, Indonesia. The posed tasks were categorized into solvable or unsolvable tasks and the domains of the level of context use and the level of cognitive processes. Results revealed that the level of context use in the posed tasks varied from zero to second order. Surprisingly, most of the tasks were in the first-order level context. Most posed tasks reached the application level, with only a few identified as reasoning tasks. Interestingly, some tasks coded as second-order context were classified as reasoning tasks. The study provides implications for designing numeracy tasks using nutrition facts and interventions in teacher education related to numeracy task design.

Abstract

This study aimed to determine the cognitive process employed in problem-solving related to the concept of area conservation for seventh graders. Two students with different mathematical ability were chosen to be the subjects of this research. Each of them was the representative of high achievers and low achievers based on a set of area conservation test. Results indicate that both samples performed more cyclic processes on formulating solution planning, regulating solution part and detecting and correcting error during the problem-solving. However, it was found that the high achiever student performed some processes than those of low achiever. Also, while the high achiever student did not predict any outcomes of his formulated strategies, the low achiever did not carry out the thought process after detecting errors of the initial solution gained. About the concept of area conservation, the finding also reveals that within the samples’ cognitive processes, the use of area formula come first before students decided to look for another strategy such as doing ‘cut-rotate-paste’ for the curved planes, which do not have any direct formula. The possible causes of the results were discussed to derive some recommendation for future studies.

Abstract

The Iceberg Design framework has been utilized to represent the progression of students’ mathematical understanding, moving from informal, contextually grounded reasoning toward formal mathematical abstraction. This study investigates how prospective mathematics teachers develop Iceberg Designs within the Realistic Mathematics Education (RME) framework, a model that enhances contextual learning and supports mathematical literacy. Thirty prospective mathematics teachers from Universitas Negeri Surabaya participated in this qualitative study, collaboratively designing Iceberg models as part of their coursework. Data from document analysis, interviews, and observations were evaluated using content analysis, the research evaluated the depth and coherence of their designs across four key components: situational contexts which evaluates the relevance and variety of real-world situations, model-of representations which examines the assistance of mathematical representation to connect the context into mathematical concept, model-for abstractions which assess the use of mathematical models toward formalization, and formal mathematical concepts which assess the mathematical ideas being explicitly involved. The findings reveal significant variation in the quality and completeness of the Iceberg Designs. Models for equivalent ratios and quadratic equations exhibited strong integration, using multiple, varied contexts to bridge situational and formal mathematical understanding effectively. Conversely, designs for fraction multiplication and quadrilateral area conservation were often surface level, relying on a single, underdeveloped context that hindered abstraction. Importantly, the study underscores the potential of Iceberg Designs to support the Sustainable Development Goals (SDGs), particularly in fostering critical thinking, practical problem-solving, and meaningful contextual learning for high quality of education (SDG 4) and decent work for sustainable economic growth (SDG 8). These insights indicate the need for deeper integration of RME principles in teacher education and curriculum development through sustained investment in this area.
