Abstract:

The ongoing dependence on conventional, lecture-centric mathematics teaching in Jamaican secondary schools has been linked to low levels of student engagement, restricted conceptual comprehension, and inadequate problem-solving results, especially in non-traditional high school environments. To address this issue, the present study sought to evaluate the efficacy of STEM-oriented teaching strategies in enhancing Grade 9 students' conceptual grasp and performance in mathematics, in contrast to traditional teaching methods. A mixed-methods research framework was utilized, involving 58 Grade 9 students from a non-traditional high school located in Half Way Tree, St. Andrew. During a five-day instructional timeframe, students participated in both STEM-integrated lessons—incorporating visual tools such as charts, graphs, and diagrams—and standard lecture-based instruction. Data collection was conducted through weekly mathematics evaluations and structured student surveys. Quantitative data were analyzed employing regression analysis and one-sample t-tests. The results indicated that STEM-based instruction had a statistically significant positive impact on student engagement, class participation, and understanding of mathematical concepts. Regression analysis revealed a moderate positive correlation between STEM variables and instructional effectiveness, while t-test outcomes confirmed significant differences favoring STEM instruction (p < 0.05). Despite facing challenges related to insufficient teacher training and resource limitations, the study concludes that STEM-focused teaching approaches are more effective than traditional methods in improving mathematical learning outcomes. The findings advocate for the incorporation of STEM pedagogy in mathematics education, particularly in under-resourced and non-traditional school settings.
