The main purpose of this study was to compare the effectiveness of case-based instruction over traditional instruction on eleventh grade high school students’ understanding of electrochemistry concepts. In addition, the effect of instruction on students’ attitudes toward chemistry, chemistry self-efficacy beliefs and motivation to learn chemistry were investigated. The study was carried out during 2010-2011 spring semester in three Anatolian high schools in Ankara, Turkey. A total of 113 (47 males and 66 females) eleventh grade students from six classes of three chemistry teachers participated in this study. One of the classes of each teacher was randomly assigned as the experimental and control group. The experimental group was instructed by case-based instruction while the control group was taught by traditionally designed instruction. Electrochemistry Concept Test, Attitude toward Chemistry Scale, High School Chemistry Self-efficacy Scale and Chemistry Motivation Questionnaire were administered as pre- and post-tests to students in both groups in order to measure the students’ understanding of electrochemistry concepts, attitudes toward chemistry, self-efficacy beliefs (self-efficacy for cognitive skills and chemistry laboratory), and motivation to learn chemistry (intrinsic motivation and relevance of learning chemistry to personal goals). In addition, semi-structured interviews were conducted with a total of twelve students from both the experimental and control groups to get deep infromation about students’ understanding of electrochemistry concepts after the post-tests were administered. Moreover, a feedback form was administred to students in the experiemental group at the end of the study to get students’ opinions about the case-based instruction. The quantitative data were analyzed via descripitive and inferential statistics. One-way Multivariate Analysis of Variance (MANOVA) was used to determine the effect of case-based instruction on students’ understanding of electrochemistry concepts, attitudes toward chemistry, self-efficacy for cognitive skills and chemistry laboratory, intrinsic motivation and perception about relevance of learning chemistry to personal goals. On the other hand, the qualitative data gathered from the interviews and feedback forms for case-based instruction were analyzed inductively. Results of MANOVA revealed that case-based instruction was an effective method to improve students’ understanding of electrochemistry concepts, attitude toward chemistry, and intrinsic motivation to learn chemistry. The qualitative data also supported the results of inferential statistics.

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...
Implementation of self-regulatory instruction based on guided inquiry approach to promote students’ achievement in solubility equilibrium and acids and bases, motivation, and learning strategies / Kadıoğlu, Cansel; Kondakçı, Esen; Department of Secondary Science and Mathematics Education (2014) 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...
Is case based instruction effective in enhancing high school students motivation toward chemistry Erdur Baker, Özgür; Boz, Yezdan (2012-01-01) The aim of this study was to investigate the effectiveness of case-based learning (CBL) over traditionally designed chemistry instruction (TDCI) on 10th grade students’ perceived motivation about chemistry as a school subject. Two classes were randomly selected from a high school. One class was assigned to be an experimental group and the other was assigned as a control group. A total of 45 high school students from 10th grade were the participants of the study (25 experimental and 20 control group students...
Effectiveness of case-based learning instruction on students’ understanding of solubility equilibrium concepts Çam, Aylin; Geban, Ömer; Department of Secondary Science and Mathematics Education (2009) The main purpose of this study is to compare the effectiveness of case- based learning method instruction over traditional method instruction on eleventh grade high school students’ understanding of solubility equilibrium concepts. In addition, students’ attitudes toward chemistry as a school subject and students’ epistemological beliefs were investigated. Sixty-two eleventh grade students from two classes of a chemistry course taught by the same teacher in Atakent High School in 2007-2008 spring semesters ...
Improving 11th grade students' understanding of acid-base concepts by using 5e learning cycle model Pabuçcu, Aybüke; Geban, Ömer; Department of Secondary Science and Mathematics Education (2008) The purpose of this study was to compare the effectiveness of instruction based on 5E learning cycle model over traditionally instruction on students’ understanding of acid-base concepts. Also, the effect of instruction on students’ attitude toward chemistry as a school subject and the effect of gender difference on understanding of acid-base concepts and attitudes toward chemistry were investigated. During the second semester of 2007-2008, 130 eleventh grade students from six classes of two different high ...
