Abstract

Conceptual understanding is a critical component of effective mathematics learning. However, many students encounter challenges in understanding mathematical concepts, including the concept of the mean. This study aims to design a learning trajectory that enhances students’ conceptual understanding of the mean. Employing a design research methodology, the study followed the stages of validation studies in creating and refining a hypothetical learning trajectory (HLT). The research consisted of three stages: preliminary design, design experiment (encompassing pilot experiment and teaching experiment), and retrospective analysis. The participants were fourty eighth-grade students from a public school in Cimahi. Data were collected through interviews, observations, documentation, and field notes, which informed iterative improvement to the HLT. Data analysis involved comparing students’ actual learning experiences with the HLT as a reference framework. The findings reveal that integrating technology and problem-based learning enhances students’ conceptual understanding of the mean, fostering creativity and real-world problem-solving skills. Based on these results, this study proposes a validated learning trajectory to support students in developing a deeper conceptual understanding of the mean.

Abstract

Problem solving refers to the process of finding ways to overcome challenges in order to achieve specific goals. In mathematics learning, problem-solving skills must be instilled from an early stage so that students are trained to solve both mathematical problems and real-life challenges. According to Polya, the steps in problem solving include understanding the problem, devising a solution strategy, implementing the strategy, and evaluating the results. Learning motivation is an internal and external drive that encourages students to enjoy and engage enthusiastically in the learning process. This motivation helps students attain optimal academic performance, as strong motivation during learning is likely to produce better outcomes. In other words, individuals with strong motivation tend to achieve better academic results. The purpose of this study is to analyze the correlation between students' learning motivation and their mathematical problem-solving skills at the junior high school level. The participants in this study were 24 students from class VIII.I at SMP Krida Utama Padalarang. The research method used was correlational analysis. Data were collected using a learning motivation questionnaire consisting of 10 positive and 10 negative statements, along with a mathematical problem-solving test on flat-sided solid shapes comprising four essay questions. The results of the study indicate a significant and strong correlation between learning motivation and mathematical problem-solving skills among junior high school students. Regression analysis shows a positive relationship in which higher learning motivation leads to greater problem-solving skills. These research findings provide insights for teachers and researchers to recognize the importance of learning motivation as a key factor in enhancing students' problem-solving skills.

Abstract

The students’ mathematical literacy skills tend to be influenced by their self-regulated learning. This study aims to analyse mathematical literacy skills based on students' self-regulated learning. The research method used was descriptive-qualitative, involving 40 students from one of the Islamic junior high schools in Bandung Barat, West Java. The instruments used were a PISA-like mathematical literacy problem and a self-regulated learning questionnaire. The data analysis technique used was the Miles and Huberman model. This model uses data collection, data reduction, data presentation, and conclusion drawing. The results showed that students with high and medium level of self-regulated learning had given correct and careful answers related to managing storage on smartphones, but the students with a moderate level of self-regulated learning were careless in performing calculations. While, students with a low level of self-regulated learning have been able to understand the problem carefully, even though they have difficulty finding the right answer. This reseach can be used as one of basis for developing more effective learning strategies that support the improvement of mathematical literacy through empowering self-regulated learning.
