dc.description.other-abstractThe effectiveness of an experimental method for improving year one high school students’ learning achievement and satisfaction in chemistry was investigated in this study. Thirty students from a high school in China were randomly assigned to participate in the study, which utilized a one-group pretest-posttest design. The research used four lesson plans focusing on chemical reactions, specifically between metal sodium and its compounds. These lessons were validated for effectiveness using the 80/80 criterion. Additionally, a chemistry achievement test and a student satisfaction questionnaire were employed, both demonstrating appropriate difficulty and discrimination indices and high reliability. The results demonstrated that the students’learning achievement in chemistry significantly improved after using the experimental method. The mean score before studying was 14.90 (SD = 2.04), while the mean score after studying was 18.43 (SD = 2.06). This difference was statistically significant at the .01 level. Furthermore, the students expressed high satisfaction with the experimental learning approach. The overall satisfaction score was 4.64 (SD = 0.49). This study suggested that utilizing experimental method as part of the chemistry curriculum can effectively enhance learning achievement and positive student satisfaction towards the subject, particularly in year one high school students.en_US
