The current study explored how the self-regulatory instruction (SRI) based on guided inquiry approach affect 11th grade students’ achievement in Solubility Equilibrium and Acids and Bases, motivation, and learning strategies compared to traditionally-designed chemistry instruction. In addition, the self-regulatory processes in which students engaged and the development of these processes over the course of the study were examined. Eleven dependent variables related to the three dimensions of SRL (motivation, cognition, and metacognition) were studied under two categories. Motivational variables included mastery-approach goal orientation, mastery-avoidance goal orientation, performance-approach goal orientation, performance-avoidance goal orientation, chemistry self-efficacy for cognitive skills, and self-efficacy for chemistry laboratory. On the other hand, cognitive variables involved achievement in Solubility Equilibrium and Acids and Bases, and rehearsal, elaboration, organization and metacognitive self-regulation strategies. Mixed Methods Design was employed: Nonrandomized Control Group Pretest-Posttest Design as a Type of Quasi Experimental Design was utilized as a Quantitative Method and Case Study was utilized as a Qualitative Method. Totally 78 students participated in the study: 38 students in the experimental group and 40 students in the control group. Quantitative data were collected using Solubility Equilibrium and Acids and Bases Test, Goal Orientation Scale, High School Chemistry Self-Efficacy Scale, and Cognitive and Metacognitive Strategies Scale. The instruments were administered as pre-tests before the intervention and as post-tests after the intervention. Additionally, four students from each classroom were selected as focal students using maximum variation sampling method. Interviews, journals, and think aloud protocols were used as qualitative instruments. Two separate mixed Multivariate Analyses of Variance were run to analyze the quantitative data: one for motivational variables and another for cognitive variables as dependent variables. In terms of motivational variables, results of quantitative and qualitative analyses revealed that SRI supported development of students’ self-efficacy beliefs; especially their self-efficacy beliefs for chemistry laboratory. Regarding cognitive variables, an improvement in students’ achievement was observed in favor of experimental group; however, its effect was less compared to self-efficacy beliefs. Although, quantitative analyses did not yield any significant difference among groups in terms of the use of cognitive and metacognitive strategies, analyses of think aloud protocols revealed that students in the experimental group used more cognitive and metacognitive strategies and in turn showed higher academic performance

The current study investigated the effectiveness of self-regulatory instruction developed based on guided inquiry on 11th grade students' use of learning strategies and achievement in chemistry, compared to traditionally designed chemistry instruction. Additionally, the self-regulatory processes in which students engaged and the development of these processes over the course of the study were examined. For this purpose, mixed-method design was employed. In total, 78 students participated in the study: 38 st...
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...
Conceptual change texts oriented instruction in teaching solution concepts
Ünlü, Yalçın; Geban, Ömer; Department of Secondary Science and Mathematics Education (2014)
This study was conducted to compare the effectiveness of conceptual change text over traditionally designed chemistry instruction on understanding of solubility equilibrium concepts. Also students’ attitudes toward chemistry as a school subject and toward conceptual change texts were investigated. Moreover, students’ science process skills and effect of the gender difference were also investigated. 108 11th grade students from four classess of a Chemistry course tought by same teacher in TOKİ Anatolian High...
Development of new synthetic methodologies for indole derivatives
Kılıklı, Ahmet Alper; Balcı, Metin; Department of Chemistry (2010)
Synthesizing nitrogen containing heterocyclic compounds is one of the leading research areas throughout the organic chemistry due to their significant activities on biological systems. Among the various biologically active molecules, indole derivatives are of prime importance on the grounds of their proven clinical roles. Objective of this study is to synthesize new indole derivatives those may contribute treatment of several diseases like their analogues via a recently developed synthetic methodology. Besi...
Implementation of case-based instruction on electrochemistry at the 11th grade level
Kondakçı, Esen (2017-10-01)
This study aims to compare the effectiveness of case-based instruction over traditional instruction in improving 11th grade students' understanding of electrochemistry concepts, attitudes toward chemistry, chemistry self-efficacy beliefs, and motivation to learn chemistry. In total, 113 students (47 males and 66 females) from three high schools participated in this study. Two of the classes from each school were randomly assigned to be either the experimental or control group. The experimental group was ins...
