Abstract

This study embarked on the development of a comprehensive Junior High School Biological Inquiry Experiment Manual. This manual was utilized in a research initiative involving 30 students in the control group and an equal number in the experimental group. Rigorous data analysis techniques, encompassing mean values, standard deviations, paired t-tests, and more were employed to meticulously evaluate the efficacy of the newly developed experimental manual. The results showed that compared with the original textbooks of D Middle School, the developed Junior Middle School Biology Inquiry Laboratory Manual helps to improve students’ interest, attitude and grade performance, so the newly developed Junior High School Biology Inquiry Experiment Manual is effective. It helps to cultivate students’ core quality of Biology. In the future, the researcher may continue refining and updating the manual to ensure its effectiveness over time, such as adding visual videos of experiments, enriching inquiry experiments on human structure and function, at the same time, researchers may consider replicating this study on a larger scope by including participants from a broader spectrum, expanding the research’s scope and depth.In the transition between the old and new curriculum standards, and under the background of double reduction, this study will lay a foundation for the in-depth development of Junior High School Biology experiment textbooks.
