Abstract

Motivation plays a crucial role in teaching and learning activities as it significantly impacts the quality of learning outcomes, particularly in mathematics. This influence becomes evident when motivation contributes to students' learning achievements. This study aimed to examine whether motivation influenced junior high school students’ learning outcomes. A quantitative approach with a descriptive correlational design was employed. The population solely comprised Year 8 students, selected using a random sampling method. Motivational questionnaires and student learning outcome tests were utilized to collect the data. The data were analyzed using simple correlation tests. The analysis showed a relatively strong positive correlation between student motivation and mathematics learning outcomes (r=0.478). The learning motivation accounted for 22.85% of the variation in learning outcomes. Thus, it can be concluded that motivation contributes to student learning outcomes, with a relatively modest impact. The findings of this study are expected to assist teachers in emphasizing student motivation and helping students attain high levels of motivation, enabling them to solve problems with ease and achieve optimal learning outcomes.

Abstract

This research is driven by the significance of representational proficiencies in acquiring mathematical knowledge. The study aimed to examine students' mathematical representational aptitude in the context of circle. A descriptive qualitative approach was employed to fulfill this purpose, and 31 Year 8 students were selected as the research sample. Data was acquired through tests and subsequent interviews. The findings revealed that students' mathematical representational abilities could be classified as very high in visual representation, high in symbolic representation, and medium in verbal representation. The high-ability group of students demonstrated proficiency across all dimensions of representation, namely visual, symbolic, and verbal. The middle-ability group exhibited proficiency in two dimensions of representation, namely visual and symbolic. The low-ability group only demonstrated proficiency in the visual aspect. Various factors influenced students' representational abilities, including challenges in generating geometric depictions, constructing mathematical models, and articulating mathematical concepts orally. Student errors during problem-solving endeavors were attributed to a lack of attentiveness to the given questions, insufficient review of previous material, limitations in problem analysis, and a deficiency in precision and experience when handling representation-related queries. It is hoped that the findings can serve as a reference for educators to enhance students' representational proficiencies.
