This study raises a number of questions needing further investigation for greater generalization. This study should be replicated with different teachers, in different types of school and communities, and with various subjects to determine if type of instruction effects academic achievement. The researcher especially recommends investigations that include the Curriculum for Agricultural Science Education (CASE), which is an inquiry-based curriculum in comparison to traditional methods use in the agricultural science classroom. In any study of methods, student factors such as internal motivation, interest in topics, prior experiences with instructional methods, and personal learning styles should also be considered to fully understand how they influence the students‘ academic achievement
