Abstract

Visual representation is crucial for enhancing students' conceptual understanding of fractions and correcting misconceptions. This explanatory-sequential mixed study assessed Indonesian preservice mathematics teachers' perceptions, self-efficacy, and implementation competencies using visual representations in fraction learning and identified gaps among these three aspects. A total of 251 students from three study programs participated in a validated online survey (α = 0.89). Quantitative data were analyzed using descriptive statistics. Seven participants were then purposefully selected for semi-structured interviews; transcripts were analyzed using Braun & Clarke's six-stage thematic analysis with researcher triangulation. The results showed that although prospective teachers had a very high perception of the pedagogical value of visual representations (M = 4.41; SD = 0.153; 78.9% agreed/strongly agreed), their self-efficacy level was only in the moderate category (M = 3.21; SD = 0.617), with only 28.3% showing high efficacy, and 61.3% were in the medium category. Implementation competence was even lower, with only 17% of participants being able to select and explain visual models pedagogically and 27.8% meeting the sufficient criteria in the teaching reasoning test. The combined analysis of quantitative and qualitative data confirmed the existence of a systemic gap between strong conceptual understanding and limited practical skills, which was mainly caused by uncertainty in model selection, minimal misconception-oriented practical experience, and weak pedagogical reflection. Integrating high-fidelity micro-teaching, representational scenario-based simulations, and video reflections is recommended to enhance self-efficacy and implementation competency.Visual representation is crucial for enhancing students' conceptual understanding of fractions and correcting misconceptions.This explanatory-sequential mixed study assessed Indonesian preservice mathematics teachers' perceptions, self-efficacy, and implementation competencies using visual representations in fraction learning and identified gaps among these three aspects.

Abstract

The integration of computational thinking in mathematics learning is essential to support 21st-century skills; however, assessment practices in schools still inadequately measure students’ thinking processes. This study aims to analyze the quality of a test instrument designed to measure junior high school students’ computational thinking ability on ratio material. A quantitative descriptive-evaluative method was employed involving 64 seventh-grade students. The instrument consisted of five contextual essay items developed based on computational thinking indicators: decomposition, pattern recognition, abstraction, generalization, and algorithmic thinking. Item analysis was conducted to examine validity, reliability, difficulty index, and discrimination power. The results indicate that all items were valid and the instrument showed high reliability (α = 0.81). The difficulty levels ranged from easy to moderate, while the discrimination power was categorized as sufficient to good. These findings demonstrate that the instrument is valid, reliable, and appropriate for measuring students’ computational thinking ability in mathematics learning at the junior high school level.
