Abstract Attitude plays a vital role in achieving modern science education goals by enhancing students’ conceptual understanding, motivation, academic performance, interest, and engagement in scientific inquiry. However, in many Ethiopian schools, attitudes toward science are often overlooked, and traditional teacher-centered instruction combined with limited resources hampers their development.

In the first stage of the intervention, the teacher and laboratory technician from the Experimental Group (EG) participated in a structured training program conducted by the researcher. This training focused on the instructional and training materials developed for the study, with a specific emphasis on the Guided Inquiry-Based Laboratory Experiments enriched Instruction (GIBLEI) approach. The training also included guidance on how to apply the 5E lesson plan format for daily lesson preparation.
