The Use of Group Investigation Learning Strategy to Improve Mathematics Learning Outcomes in Vocational High School Students
Abstract
The learning outcomes of students in class XI of SMK Negeri 1 Bengkalis are unsatisfactory because the scores are below the completion level. This is due to the lack of varied learning strategies. This research aims to improve mathematics learning outcomes by applying group investigation strategies. The formulation of the problem in this study is whether the application of group investigation strategies can improve the learning outcomes of mathematics students in class XI SMK Negeri 1 Bengkalis. This classroom action research (PTK) was conducted in 1 cycle with five meetings. The subjects of this study were students of class XI SMK Negeri 1 Bengkalis, totalling 20 people. The results showed that learning by applying a group investigation strategy on Statistics material can improve students' mathematics learning outcomes in class XI SMK Negeri 1 Bengkalis. This is evident from the percentage of student learning completeness, which reached 79.5%.
