Implementation of the Case Method in Learning Mathematics to Improve the Creative Thinking Ability of Electronics Engineering Students

Learning in class found that lecturers did not give students the opportunity to think creatively in solving math problems. Learning is still centered on the teacher so that communication is still one-way resulting in teacher dominance. The research objective resulted in the implementation of the case method in mathematics learning to improve the creative thinking skills of D4 Electronics Engineering students in solving mathematical problems. This type of research is experimental by using data collection documentation, questionnaires, observations and tests. The research was conducted in class 1B in the even semester of the 2022/2023 academic year with a total of 24 students discussing the Linear Equation System material. Data analysis used normality test, homogeneity test, completeness test, comparative test, and n-gain test. The results showed that the results of the validation of the research instrument were 4.11 in the good category. Individual completeness tests meet the minimum completeness criteria, students' creative thinking skills in case method group are higher (81.56) than expository learning (70.05). N-gain score for creative thinking test of 0.363 which is in the medium category.

Keywords: case method, system of linear equations, creative thinking ability.
