Abstract

Students need speaking skills to express their opinions in front of the class; however, many students still lack confidence in speaking. This study aimed to investigate whether students taught using the Project-Based Learning (PjBL) model had better speaking skills than those taught using the cooperative learning model. This research employed a quasi-experimental design with a Posttest-Only Control Group design. The population consisted of fifth-grade students at SDN Gayungan II Surabaya, and samples were selected using cluster random sampling, with class V-A as the experimental class and class V-B as the control class. Data were collected through tests, observations, and documentation. Test data were analyzed using inferential statistics with SPSS, while data from student activities and learning implementation were analyzed descriptively. The results showed that students taught using the PjBL model had significantly better speaking skills than those taught using the cooperative learning model.

Abstract

This study investigates the influence of mathematics anxiety on the critical thinking processes of primary school students when solving numeracy tasks. Using a qualitative case study design, data were collected through written responses and follow-up interviews with students categorized according to their levels of mathematics anxiety. Analysis focused on three indicators of critical thinking: clarification, strategy, and inference. The findings show that students with high mathematics anxiety typically demonstrated the ability to extract key information from problem statements and diagrams, demonstrating strength in clarification. However, their ability to formulate strategies and provide justified inferences was limited, as they often relied on rote recall, omitted calculation steps, and expressed uncertainty about their answers. These patterns show how anxiety specifically hampers the ability to perform calculations and make confident decisions, even when students demonstrate basic comprehension. The study underscores the need for pedagogical approaches that simultaneously develop numeracy skills and address affective barriers, thereby supporting students’ capacity to engage in reasoning and problem solving more effectively.

Abstract

Purpose: This study explores the effect of culturally responsive teaching (CRT) and learning motivation on numeracy achievement among elementary students in coastal West Papua, Indonesia. It investigates how integrating local cultural contexts into mathematics instruction and fostering student motivation can enhance learning outcomes. Method: A quantitative ex post facto design was applied, involving 30 third-grade students from SD Negeri 35 Kimindores. Data were gathered through a culturally responsive teaching scale, a learning motivation questionnaire, and a contextual numeracy test. Multiple regression analysis was used to assess the relationship between these factors. Finding: The analysis revealed that both culturally responsive teaching and learning motivation significantly impacted numeracy achievement, explaining 69% of the variance in students' performance. Students exposed to culturally relevant lessons showed greater motivation and improved numeracy skills. Significance: The study highlights the value of culturally responsive pedagogy in improving student engagement and achievement in mathematics. By aligning lessons with students' cultural contexts, educators can make learning more meaningful and inclusive. This research emphasizes the need for culturally grounded teaching strategies, particularly in remote areas, to ensure educational equity and foster deeper learning.

Abstract

Purpose: This study aims to understand how the cultural elements of Surabaya’s Tugu Pahlawan Monument can be used to introduce basic numeracy in primary school, especially concepts related to plane geometry. The goal is to show that cultural landmarks can offer real and relatable examples for young learners. Method: The research was conducted through a qualitative ethnographic approach. The researcher observed the monument directly, spoke with on-site guides and staff who were familiar with its history, and documented various architectural and visual features. All information gathered from notes, photographs, and short interviews was analyzed using the Miles and Huberman framework to identify patterns that relate to mathematical ideas. Findings: The study found that many parts of the monument display clear geometric forms. These include rectangles, squares, circles, triangles, trapezoids, rhombuses, and even a ten-sided figure. Such shapes appear in the floor patterns, plaques, murals, decorative ornaments, museum structures, and the wheels of military displays. Each of these elements can be directly connected to geometry topics taught in primary classrooms. Significance: The findings highlight the potential of local heritage as a meaningful resource for mathematics education. When students see that the shapes they learn in class appear in a monument tied to their own city’s history, mathematical concepts become easier to grasp and more engaging. This approach supports early numeracy while also helping learners build a stronger connection to their cultural environment.

Abstract

Numeracy literacy competency among students who are classified as low. Apart from this, in mathematics learning, some teachers only use textbooks and a lack of teaching materials to support learning, which causes a lack of student interest and monotony in mathematics learning, so teaching materials are needed that are integrated with numeracy literacy in order to grow students' numeracy literacy competencies. The aims of this research are (1) to describe the process of developing mathematics teaching materials based on numeracy literacy, (2) to determine the feasibility of mathematics teaching material products based on numeracy literacy. The development model in this research is a 4D model. There are four stages in the 4D model, including Define, Design, Development and Disseminate. However, the development research carried out only uses the 3D stage or up to the Development stage. In this development research, data collection techniques were used, namely unstructured interviews and questionnaires and used qualitative data analysis techniques and quantitative data analysis techniques. The results of the research are (1) a mathematics teaching material product based on numeracy literacy in scale and comparison material in elementary schools. Based on the results of the assessment scores obtained by experts (material experts, media experts and language experts), it was found that (2) feasibility test results for the product development of mathematics teaching materials based on numeracy literacy in scale and comparison material in elementary schools received the "Very Feasible" category.
