Abstract

The integration of computational thinking (CT) has become increasingly essential in mathematics education, particularly in topics that require spatial reasoning and structured problem solving, such as flat-surfaced solid geometry. This study aims to synthesize empirical evidence on students’ computational thinking abilities within this specific mathematical context through a Systematic Literature Review (SLR). Using a descriptive qualitative approach, this review analyzed seven peer-reviewed articles published between 2020 and 2025 in nationally accredited journals indexed at SINTA levels 1–5. The literature search was conducted using Google Scholar and Publish or Perish, guided by predefined inclusion and exclusion criteria, and the study selection process followed PRISMA guidelines. The findings reveal that students’ computational thinking abilities are generally at low to moderate levels and unevenly developed across indicators, with abstraction and decomposition more prominent than pattern recognition and algorithmic thinking. Instructional designs incorporating visualization, contextualization, and structured problem engagement effectively supported CT development, whereas unplugged and manipulative-based activities proved beneficial at the elementary level. However, most studies emphasize outcome-based assessments and provide limited insight into students’ cognitive processes during problem solving. These findings highlight the need for theoretically grounded instructional designs and process-oriented assessment frameworks to support a more integrated and sustainable development of computational thinking in geometry learning.

Abstract

This study aims to analyze the mathematical generalization ability of junior high school students in Cilegon City on the topic of relations and functions. Mathematical generalization ability is an important component of higher-order thinking that includes the ability to recognize patterns, express regularities, and represent mathematical relationships in symbolic form. The method used was descriptive quantitative, involving 368 students from 50 schools that are members of the Mathematics Subject Teachers Association (MGMP) of Cilegon City. The research instrument consisted of six open-ended questions developed based on three indicators of generalization ability proposed by Mason, Sitorus, and Sutirna (2023): perception of generality, expression of generality, and symbolic and manipulation of generality. Data were analyzed descriptively through the calculation of mean scores and ability category classification. The results of the study show that students’ mathematical generalization ability is in the moderate category with an average score of 2.08. The indicators of perception of generality and expression of generality are also in the moderate category, while symbolic and manipulation of generality falls into the low category. These findings indicate that students are able to recognize patterns and express simple relationships, but still experience difficulties in constructing formal symbolic representations. Based on these results, mathematics learning needs to be more oriented toward exploration, conceptual reasoning, and the use of interactive visual media to improve students’ symbolic representation skills and functional understanding.
