This study was conducted to determine the effectiveness of AGHAMazing technique in improving the academic performance of Grade 9 students in science.The study used the experimental method of research comparing the AGHAMazing technique to traditional technique in teaching science. A teacher- made pre-test and post-test employed to check the performance of the students who participated in the study. T-test analysis was used by the researcher to compare the significant difference between the two variables. Results of the pre-test and post-test revealed that AGHAMazing technique is more effective method in improving the academic performance of Grade 9 students in science compared to traditional method. The study recommends that science teachers can use/ try updated and relevant teaching techniques to uplift the academic performance of the students. Personnel in the Department of Education should initiate programs/ activities, trainings and seminars to equip the teachers with latest trends, issues and concerns to further stimulate their teaching competency especially in the conduct of teaching- learning process. In addition, this will develop the teacher to become 21st century teacher to produce 21st century students.
