    Analysis of Argumentation and Questioning Patterns in Argument-Based Inquiry Classrooms
    (TURKISH EDUCATION ASSOC, 2012) Gunel, Murat; Kingir, Sevgi; Geban, Omer
    The purpose of this study was to analyze the argument-based inquiry approach implementations with respect to questioning in the classrooms. In addition, the study aimed to explore the relationship between levels of questioning and negotiation of ideas. The study was conducted with three teachers and 146 students. The video transcripts obtained from these teachers' classrooms were analyzed through discourse analysis. The findings indicated that teachers' questioning and implementation level are two crucial factors in starting and sustaining the negotiation of ideas in science classrooms. In addition, a relationship was detected among teachers' questioning patterns, number and type of questions generated by students. Finally, the talk moves used by the teacher facilitated students' talk and negotiation.

    Using the Science Writing Heuristic Approach to Enhance Student Understanding in Chemical Change and Mixture
    (SPRINGER, 2013) Kingir, Sevgi; Geban, Omer; Gunel, Murat
    This study investigated the effect of the Science Writing Heuristic (SWH) approach on grade 9 students' understanding of chemical change and mixture concepts. Four intact classes taught by two chemistry teachers from a Turkish public high school were selected for the study; one class was assigned as the treatment group, and the other class was assigned as the comparison group. Students in the treatment group were instructed by the SWH approach, while those in the comparison group were instructed with traditionally designed chemistry instruction. Tests measuring students' conceptual understanding in the units of chemical change and mixture were administered as pre- and posttest for both groups. At the end of the instruction, semistructured interviews were conducted with 13 students from the treatment group and eight students from the comparison group. ANCOVA results revealed that the SWH approach was superior to the traditional approach on students' understanding of chemical change and mixture concepts. Interview results indicated that students in the treatment group demonstrated better scientific understanding of chemical change and mixture concepts compared to those in the comparison group.
