EFFECTS OF SHORT-TERM STEM INTERVENTION ON THE ACHIEVEMENT OF 9TH GRADE STUDENTS IN MATHEMATICS.

The aim of this study is to examine the effect of the STEM approach on students’ achievements in processing teaching topics from Algebra. A quasiexperimental design was used with an experimental and control group. The research was conducted on a sample of 73 ninth-grade students (aged between 14 and 15). STEM approach was performed in teaching the experimental group, while the control group was taught in a traditional way. The obtained results showed that the STEM intervention had a positive impact reflected in significantly better results on the achievement tests. The girls performed better than boys on all tests.
