Abstract

Background: In today's ever-changing landscape, students need strong numerical literacy skills to navigate life's complexities. Recognizing that students come with various learning capabilities, often referred to as "instructional levels," educators must think outside the box when it comes to teaching methods.Aim: This study aims to 1) gauge whether creative problem solving (CPS) or scientific learning is more effective in enhancing the numerical literacy skills of MA students; 2) assess the difference in the numerical literacy progress among MA students categorized at independent, instructional, and frustration levels; and 3) explore the interplay between teaching methods and instructional levels on students’ numerical literacy development.Method: Conducted as an experimental study, this research employs a 3x2 factorial design. Participants include students from Class X IPA at MAN 2 Serang. To collect data, we used tests focused on numerical literacy as well as assessments to categorize instructional levels. A two-way ANOVA serves as the statistical approach to test our hypotheses.Result: 1) MA students exposed to the CPS method showed greater improvements in their numerical literacy skills than those who engaged in scientific learning; 2) A noticeable variance exists in the growth of numerical literacy skills among MA students at independent, instructional, and frustration levels; 3) An interaction effect was identified between the chosen teaching method and the instructional level in shaping the numerical literacy skills of MA students.Conclusion: The study concludes that creative problem-solving is more potent than scientific learning in elevating the numerical literacy of MA students. Furthermore, instructional levels play a crucial role in this improvement. A synergistic effect between the teaching approach and instructional level was also found to influence the numerical literacy outcomes.

Abstract

The ability of mathematical representation helps students solve mathematical problems in forms that are easy to understand and more concrete, so that they can maximize their potential for achievement in learning mathematics. The purpose of this study was to describe the mathematical representation abilities of junior high school students on the concept of congruence in terms of learning styles. The subjects of this study were 35 grade VIII junior high school students using a random sampling technique. Data collection was carried out using mathematical representation ability tests, learning style questionnaires, and interviews. After that, it was analyzed using triangulation techniques to determine the validity of the data. The results showed that on average, students have very good visual representation abilities with auditory, visual, and kinesthetic learning styles because all students can solve questions correctly according to the indicators. Students who have the ability to represent good expressions or equations have a visual learning style. Whereas students with word representation abilities cannot be said to be good because of the existing subjects, there are no students with any learning style who can solve word representation ability questions correctly. Based on this, it can be concluded that the low representation ability of students is not influenced by their learning styles, both visual, auditory, and kinesthetic, especially in the concept of congruence.

Abstract

Background: Metacognition significantly influences students' effectiveness in solving mathematical problems. Variability in metacognitive patterns among students is shaped by factors such as adversity quotient (AQ) and gender.Aim: This research aimed to explore metacognitive patterns in mathematical problem-solving among students majoring in mathematics at Universitas Muhammadiyah Jakarta, with a specific focus on differences due to AQ and gender.Method: Adopting a qualitative approach with a phenomenological framework, this study included six students (three males and three females) from the 2021–2022 academic year. These students represented different AQ categories: climber, camper, and quitter. Data collection involved tests, observations, and interviews.Results: The investigation showed that students with a climber AQ, irrespective of gender, adeptly utilized all metacognitive knowledge facets: declarative, procedural, and conditional. In contrast, male campers engaged primarily in declarative and procedural knowledge, while male quitters demonstrated negligible engagement. Female campers predominantly employed declarative knowledge, occasionally integrating conditional knowledge. Female quitters, however, did not exhibit significant usage of metacognitive knowledge. Regarding metacognitive regulation—planning, monitoring, and evaluation—students identified as climbers displayed proficiency across all these aspects, regardless of their gender.Conclusion: The study underscores the influence of AQ and gender on metacognitive patterns in mathematical problem-solving, noting an exception in climbers who consistently exhibit effective metacognition. These insights could guide educational strategies to bolster metacognitive skills in the context of mathematics education.

Abstract

Background:Understanding fractions in mathematics often poses greater complexity compared to integral numbers. The primary difficulty lies in students' inadequate grasp of fractional basics, notably in comparing and sequencing fractions.Aim: This research seeks to create and evaluate a learning pathway's effect on fourth graders' comprehension of fractions, with a focus on their comparison and sequencing.Method: Employing a design research validation study approach, the research progresses through preliminary design, experimental design, and retrospective analysis. Conducted in a Palembang school involving six fourth graders recommended by their teacher, data collection encompassed essay-based pre and post-tests, Student Activity Sheets, observations, interviews, and documentations. The data analysis was retrospectively carried out, anchored on HLT as the benchmark.Result: Findings reveal a student learning trajectory encompassing three principal activities. Initially, students used folding and gluing of paper to discern fraction values. Subsequently, they engaged in coloring and illustrating folds for fraction comparison. The final activity involved drawing, coloring boxes, and fraction comparison and sequencing. Overall, students showed proficiency in understanding and determining fraction values and comparing them, yet struggled with ordering certain fractions.Conclusion: The structured learning path facilitated students' understanding of basic fraction concepts, especially in comparing them. Nevertheless, reinforcing methods or approaches for teaching fraction ordering is essential.
