The study investigated the impact of the first principle approach (FPA) on students’ performance in determining limiting reagents in chemical stoichiometry. A quasi-experimental design, involving 120 science students from two colleges of education in Ghana, was adopted. Sixty (60) students each were randomly assigned to the experimental group (EG), which was taught using FPA, and the control group (CG), which followed traditional teaching approach (TTA). Data on students’ entry knowledge (EK) and their performance on algorithmic problems (AP) and conceptual problems (CP) were collected and analyzed using descriptive and inferential statistics. The mean scores for EK were moderate for both groups (EG: 66.00%; CG: 68.30%). After treatments, there was no statistically significant difference in the groups’ performance on AP. However, the EG significantly outperformed the CG on CP, indicating that FPA enhanced students’ conceptual understanding of limiting reagents. The findings suggest that FPA is an effective teaching strategy for fostering deeper conceptual understanding and problem-solving skills in stoichiometry. This study highlights the importance of incorporating FPA into chemistry education to improve students’ ability to determine limiting reagents.
