Effect of Jigsaw method on students’ scientific attitude in laboratory course: Comparison of Anderson-Rubin and raw factor scores

Abstract

Aim of this study is to investigate the effect of Jigsaw on students’ scientific attitude. Study design is qualitative methods’ pre experimental nonequivalent groups posttest design. In this research design, pre-condition of the groups are unknown. Only the after condition of the groups are investigated and results are about after procedure. Sample of the study consisted of students who studied at elementary science education program. With respect to research design, students were divided randomly into two groups for laboratory course. First group studied with respect to Jigsaw method while second groups studied with respect to traditional method. After completing the semester students were asked to respond scientific attitude scale. Only volunteered students were involved in the study. Thus, sample of the study consists of 10 students from the traditional group and 17 students from the jigsaw group. Number of the sample is 27 in total. Non parametric analyses were run for group comparisons. Data for statistics are based on raw scale scores and Anderson-Rubin factor scores. Analyses results showed that there is no significant difference between the groups in terms of scientific attitudes. However, Anderson-Rubin factor scores gave more sensitive p value when compared with raw factor scores.
