Abstract:

The aim of this research is to analyse the effects of argument-based science inquiry (ABSI) approach utilized within the unit of "reproduction, growth and development in living beings" on the reasoning skills and success levels of students. The main objective of this study is to determine the effects of ABSI on reasoning skills and level of ability to answer multiple choice and open-ended questions of sixth grade students. The sample of the research consists of 88 students of Dilek Özer Junior High School, in the County of Nilüfer, Bursa. The research was conducted in three classes of sixth graders. Mixed method was adopted as the research method. Two of the three classes were designated as the experimental group and one was the control group. The unit of "reproduction, growth and development in living beings" was handled according to ABSI method within the experimental group, whereas the control group just proceeded as usual. The study was concluded in 5 weeks. In order to collect data, pre-test and post-test were applied before and after the study. Success tests with multiple choice and open-ended questions were used as data collecting tool. Obtained data were analysed quantitatively and qualitatively. Quantitative data were compared by using "Independent Samples t Test" on SPSS statistics programme. Voice records of the lessons of the experimental and control groups were kept as a qualitative data collecting tool. The data obtained from the voice records were tabulated by applying content analysis. Where the results of the analysis didn't show vital differences between the answers to the multiple choice questions of the experimental and control groups, significant differences were identified in the answers of these groups to open-ended questions where reasoning and explanation were required. The analysis of the transcripts of the voice recordings indicated that the frequency of multiple teacher-student-student communication of the experimental group was much higher than of the control group. On the other hand, the control group showed significantly higher teacher-student one way communication. As a result of the study, it is clear that the ABSI method is more effective in open-ended questions where interpretation is required. Moreover, the study has shown that this method increases the lesson related activity of the students and improves their conceptual understanding, and reasoning and argumentation skills. Improving the questioning and argumentation skills of the students prior to the secondary education may make it easier to apply the ABSI method in junior high and also facilitate to obtain more effective results from the method.
