Improving Mathematics Learning Outcomes Through Problem-Based Learning: A Study on Vocational High School Students in Class XI
Abstract
This study contributes to improving the learning process of Mathematics among KKBT 1 SMK 4 Pekanbaru Stage 11 students in the school year 2023/2024 and improving their academic performance in Mathematics. The format of this study was classroom action research (CAR) conducted in two cycles, each consisting of six stages: providing motivation, identifying problems, collecting data, processing data, and proving and drawing conclusions. The study subjects were the students of class XI of KKBT 1 SMK 4 in Pekanbaru, totaling 33 students. Data were collected through observation and testing techniques. The tools used included learning tools, teacher and student activity observation forms, and mathematics learning outcome test forms. The data analysis findings showed that the learning process aligned with the lesson plan, and the students were active in the classroom. In addition, the number of students achieving the KKTP increased, i.e., the basic score was 8 or 24.24%; Cycle I increased to 13 or 39.39%; and Cycle II increased to 24 or 72.72%. Thus, through the application of the problem-based learning model, the learning process of the students of KKBT 1 SMK 4 Pekanbaru class XI, stage F, on the material of scatter diagrams for the even-numbered semesters of the academic year 2023/2024 has been improved, and their performance in mathematics has increased.
