Abstract

This study aims to describe students' errors in solving mathematics problems based on their conceptual understanding. This research employed a descriptive qualitative approach involving 28 eighth-grade students from SMP Negeri 1 Latambaga. Data were collected using a conceptual understanding test, designed based on several indicators (classifying objects according to their properties, giving examples and non-examples of a concept, applying concepts algorithmically, and presenting concepts in various representative forms). Student errors were analyzed using Nolting's theory, which categorizes errors into careless, concept, application, and test procedure errors. The instrument was validated by mathematics education experts and teachers, and tested for item validity. After the test, four students representing different ability levels (high, medium, low, very low) were selected for interviews. The results showed that, in general, students' conceptual understanding was low. The most dominant errors were concept and application errors, while procedural and careless errors also appeared but less frequently. In conclusion, students' errors are primarily caused by weak conceptual understanding and a lack of systematic problem-solving abilities.

Abstract

This descriptive study aims to analyze students' difficulties in solvingmathematical word problems based on their critical thinking skills. Thestudy was conducted at SMA Negeri 1 Tanggetada, involving 26 studentsas research subjects using purposive sampling technique. Several studentsrepresenting different categories of critical thinking skills were selectedfor interviews based on their test results. The results showed that, onaverage, students experienced a 68.97% difficulty level across allindicators, indicating a high category of difficulty. Among the indicators,students had the greatest difficulties in drawing conclusions (93.59%) andperforming calculation operations (87.18%). Furthermore, the students’critical thinking skills were found to be very low, with an average score of10.9.

Abstract

Rotation model on digital literacy and critical thinking skills among Mathematics Education students of the 2022 cohort at Sembilanbelas November University, Kolaka. With the increasing need for digital literacy and critical thinking skills in modern education, blended learning models such as Stage Rotation offer potential solutions to meet these demands in the technological era. A quasi-experimental method with a One Group Pretest-Posttest design was employed, involving a total sample of 15 students. Digital literacy and critical thinking skills were assessed using a likert scale questionnaire and essay test, respectively. The research instruments were validated to ensure reliability, and statistical analysis was conducted using a paired sample T-test to evaluate the effectiveness of the learning model. The results revealed a significant improvement in digital literacy and critical thinking skills following the intervention. These findings suggest that the blended learning model is an effective pedagogical strategy and has the potential to be implemented in curriculum courses. Further research is recommended to explore the impact of this model in other educational contexts to enhance the generalisability of the findings.
