Abstract

This study aims to evaluate students’ creative thinking abilities in solving mathematical problems related to the topic of integers using the Systematic Literature Review (SLR) method. The SLR involved critically analyzing 15 relevant scientific articles published in the last five years. The findings reveal that students’ overall creative thinking ability remains at a low level, particularly in the indicators of originality and elaboration. Most students are only able to demonstrate fluency in generating answers, but they struggle to produce unique solutions or elaborate ideas in depth. Several factors contribute to this condition. First, most math problems used in schools are closed-ended, emphasizing one correct answer and failing to encourage idea exploration. Second, teaching approaches still tend to be procedure-oriented, training students to memorize steps rather than understand underlying concepts. Third, internal student factors such as low academic confidence and limited problem-solving skills also hinder the development of creative thinking. This study suggests the importance of designing open-ended, contextual, and challenging problems to stimulate all aspects of creative thinking, including fluency, flexibility, elaboration, and originality. Furthermore, teachers are encouraged to adopt more explorative and student-centered approaches in the classroom to foster a culture of creative thinking from an early stage of learning.

Abstract

The study aims to determine the process and influence of creative thinking skills of class X students of SMK Kreatif Bahrul Ulum before and after implementing the discovery learning model. The research method used is pre-experimental design with one-group pretest-posttest design and using a quantitative approach. The subjects of this study were class X students of SMK Kreatif Bahrul Ulum Tambakberas. The research instruments used were tests and non-tests. The test instrument was in the form of pretest and post-test essay questions to measure students' creative thinking skills using discovery learning. The data analysis technique used was hypothesis testing. The data obtained were first tested for normality and homogeneity. Based on the calculation of the paired sample t test, it showed that the t count value was 19.453 with a significance of 0.000. The significance value shows 0.000 <error level of 0.05, so it can be concluded that Ha is accepted. So it can be concluded that there is an increase in the creative thinking skills of class X students of SMK Kreatif Bahrul Ulum Tambakberas before and after implementing the discovery learning model.

Abstract

The objective of this study is to develop a web-based learning tool that can be used for matrix operations (addition, subtraction, and multiplication) as well as for calculating the determinant of a 4×4 matrix. As an alternative to the complex cofactor method for determinant calculation, an adapted version of the Sarrus method is utilized. The research and development (R&D) process follows a digital learning media development approach, consisting of needs analysis, prototype design, implementation, and evaluation stages. This learning tool integrates basic matrix operations with an extended adaptation of the Sarrus method, incorporating A1, A2, and A3 components for 4×4 matrices. This method enables determinant calculations to be performed in a more systematic and efficient manner compared to the cofactor method, while basic matrix operations provide a comprehensive understanding of linear algebra. The study results indicate that an interactive web-based learning resource has been successfully developed. The tool features an integrated calculator for matrix addition, subtraction, and multiplication operations, as well as determinant calculations with step-by-step visualizations. The creation of this learning tool simplifies previously complex calculations while significantly improving time efficiency for both basic operations and determinant calculations.
