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.

Using the science writing heuristic approach to promote student understanding in chemical changes and mixtures Kıngır, Sevgi; Geban, Ömer; Günel, Murat; Department of Secondary Science and Mathematics Education (2011) The purpose of the present study was to investigate the effect of Science Writing Heuristic (SWH) approach on 9th grade students’ understanding of chemistry concepts and chemistry achievement in chemical changes and mixtures units. Four 9th grade classes taught by the two chemistry teachers from a public high school were selected for the study. Each teacher’s one intact class was assigned as the experimental group and the other class was assigned as the control group. Students in the experimental group were...
Exploring the Effects of Science Writing Heuristic Approach on 8th Grade Students Metacognition Tucel, Tuğçe; Çakıroğlu, Jale; Öztekin, Ceren (2015-09-04) The purpose of this study was to explore the effects of Science Writing Heuristic (SWH) approach on middle school students' metacognition. For this purpose, a quasi-experimental research design, the non-equivalent control group post-test only design was used with the aim to compare the experimental and the comparison groups mean difference with respect to dependent variables. 60 eight grade students with a mean age of 14 years in two classes selected from one public school in an urban area. One class was ra...
Promoting Conceptual Change in Chemical Reactions and Energy Concepts through the Conceptual Change Oriented Instruction Ceylan, Eren; Geban, Ömer (2010-07-01) This study was designed to investigate the effectiveness of the conceptual change oriented instruction through demonstration over traditionally designed chemistry instruction on 10th grade students' understanding of chemical reactions and energy concepts and their attitudes towards chemistry as a school subject. One of the groups was defined as control group in which students were taught by traditionally designed chemistry instruction (TDCI), while the other group defined as experimental group in which stud...
The effect of cooperative learning approach based on conceptual change conditions on students understanding of chemical equilibrium Bilgin, İbrahim; Geban, Ömer; Department of Secondary Science and Mathematics Education (2002) The purpose of this study was to investigate the effects of the cooperative learning approach based on conceptual change conditions over traditional instruction on 10th grade students' conceptual understanding and achievement of computational problems related to chemical equilibrium concepts. In addition, the effects of students' performance in small group work on the students' conceptual understanding and achievement of computational problems related to chemical equilibrium was investigated. mThe subjects ...
Facilitating Conceptual Change in Rate of Reaction Concepts Using Conceptual Change Oriented Instruction KAYA, EBRU; Geban, Ömer (2012-01-01) The purpose of this study was to investigate the effects of conceptual change-oriented instruction through demonstrations (CCOITD) on 11th grade students' understanding of rate of reaction concepts when compared to traditionally designed chemistry instruction (TDCI). The sample consisted of 69 11th grade students from two classes in a public high school. Reaction Rate Concept Test was administered to both groups as a pretest and posttest to assess students' understanding of the concepts. The data was analyz...
