Abstract

Early numeracy constitutes a fundamental competency that influences students’ future mathematical achievement. Nevertheless, many first-grade students experience difficulties in understanding addition and subtraction because mathematical concepts are often presented symbolically and abstractly. This study investigated the effect of concrete manipulatives on students’ numeracy skills in primary mathematics learning. The research employed a quantitative approach using a pre-experimental one-group pretest-posttest design. Participants consisted of 33 first-grade students of SDK Santo Yoseph 4 Kupang selected through total sampling. Data were collected using achievement tests measuring addition and subtraction skills. The findings revealed a substantial improvement in students’ performance after the intervention. The mean pretest score was 54.57, whereas the mean posttest score increased to 85.30. Paired-sample t-test analysis demonstrated a statistically significant difference between pretest and posttest scores (p < .001). The findings indicate that concrete manipulatives effectively facilitate conceptual understanding by transforming abstract mathematical symbols into observable and manipulable representations. The study contributes empirical evidence supporting constructivist and cognitive-developmental perspectives emphasizing the importance of hands-on learning experiences in early mathematics education. The integration of concrete media is therefore recommended as an instructional strategy to strengthen foundational numeracy competencies in lower primary classrooms.

Abstract

Teacher creativity in classroom management is considered an essential factor in creating meaningful learning experiences and improving students' understanding of learning materials. However, classroom instruction in elementary schools is often still teacher-centered, resulting in limited student engagement and suboptimal learning outcomes. This study aimed to examine the relationship between teacher creativity in classroom management and students' understanding of learning materials among third-grade students at UPTD SDI Kuanino 2. The study employed a quantitative approach using a correlational research design. The population consisted of 21 third-grade students, all of whom were selected as the research sample through total sampling. Data were collected using Likert-scale questionnaires measuring teacher creativity in classroom management and students' understanding of learning materials. The research instruments were tested for validity and reliability before data collection. Data analysis included descriptive statistics, the Shapiro–Wilk normality test, and Spearman Rank correlation analysis because the data were not normally distributed. Descriptive analysis indicated that teacher creativity in classroom management was in the good category (77.56%), while students' understanding of learning materials was also categorized as good (76.25%). The findings revealed a positive and significant relationship between teacher creativity in classroom management and students' understanding of learning materials. These findings indicate that improving teacher creativity in managing classroom learning contributes to better student understanding. Therefore, teachers are encouraged to continuously develop innovative classroom management strategies to enhance learning quality in elementary schools.
