Abstract

This study aims to analyze the problem-solving and critical thinking abilities of prospective mathematics teachers in solving Higher Order Thinking Skills (HOTS) problems on lines and angles through error analysis. The study employed a qualitative descriptive approach. The research subjects consisted of 20 fourth-semester students of the Mathematics Education Study Program at Institut Pendidikan Tapanuli Selatan (IPTS). Data were collected through HOTS geometry tests, task-based interviews, and documentation of students’ written work. Error analysis was conducted using Newman’s Error Analysis (NEA), while critical thinking and problem-solving abilities were analyzed using the FRISCO and Krulik-Rudnick frameworks. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña, which includes data reduction, data display, and conclusion drawing. The results showed that students’ abilities were still in the moderate to low category. The dominant errors occurred at the transformation and process skills stages, indicating difficulties in converting visual representations into mathematical models and selecting appropriate solution strategies. In addition, students demonstrated weaknesses in critical thinking, particularly in reasoning, inference, and overview indicators. These errors were influenced by epistemological and ontogenic obstacles related to weak spatial ability and conceptual understanding of geometry. Therefore, HOTS-based learning emphasizing visualization, critical thinking, and systematic problem-solving is needed to improve prospective teachers’ mathematical abilities.

Abstract

In the context of education, literacy is no longer understood merely as the ability to read and write. It also includes the capacity to understand texts, interpret meaning, evaluate information critically, communicate ideas effectively, and apply knowledge to solve real-life problems. Therefore, this study aims to develop an Augmented Reality (AR)-based E-Comic by integrating Baduy folklore, meeting the criteria of validity, practicality, and effectiveness in optimizing English literacy skills. This study employs Research and Development (R&D) approached to create and evaluate an educational product. It follows the ADDIE model, which consists of five systematic stages: Analyze, Design, Development, Implementation, and Evaluation. The development of this E-Comic is designed to provide a contextual learning experience supported by dynamic and interactive 3D visualizations, thereby enhancing students’ literacy skills, particularly in English. The findings indicate that the developed AR-based e-comic was positively received by students and is suitable for use as teaching material in English language learning. This is consistent with other studies indicating that e-comics improve learning comprehension and are highly relevant as teaching media. This is also consistent with the results from utilizing digital teaching materials as an alternative for English classes. The average score from media experts reached 91.3%, while student responses averaged 84%, both categorized as highly feasible. Therefore, the product can be effectively implemented as a teaching material for English language learning.
