This study investigates elementary teachers' perceptions of traditional science teaching methods within the Single National Curriculum (SNC) at the elementary level. The primary objectives were to evaluate the science achievement of Grade IV students using both cooperative and traditional teaching methods, to compare the effectiveness of these methods based on students' ability levels, and to assess their impact across different science content areas. The study involved 69 elementary teachers, who provided data through a self-developed questionnaire, validated and tested for reliability using Cronbach’s Alpha during a pilot study. The data, collected via oral explanations followed by questionnaire completion, were analysed using statistical techniques such as mean and standard deviation. The findings reveal a preference among some teachers for traditional methods, citing their effectiveness in content delivery. However, there is also recognition of the need to enhance these methods with innovative techniques to improve student engagement and understanding. The study recommends refining traditional teaching approaches by integrating technology and experiential learning opportunities, ensuring a more comprehensive and effective science education experience for elementary students within the SNC framework.
