The purpose of this study was to investigate the effect of instruction based on 5E learning cycle model (LCI) compared to Traditional Instruction (TI) and gender on 11th grade students’ understanding of solubility equilibrium concept, students’ perceived motivation, use of learning strategies, and attitudes towards chemistry. There were 53 students in the experimental group instructed by the LCI and 56 students in the control group instructed by the TI. Solution Concept Test and Science Process Skills Test were administered to students in both groups as a pre-test. Attitude Scale towards Chemistry and Motivated Strategies for Learning Questionnaire were given to students in both groups before and after the treatment. Moreover, Solubility Equilibrium Concept Test was administered to both groups as a post-test and retention test two months after treatment. Treatment implementation continued for seven weeks. After the instruction, semi-structured interviews were conducted with six students from experimental group and six students from control group. Data were analyzed by using MANCOVA. The results revealed that LCI was more effective than the TI on students’ understanding and retention of the solubility equilibrium concepts. In addition, LCI improved students’ attitudes towards chemistry, intrinsic goal orientation, task value, self-efficacy for learning and performance, rehearsal, elaboration, organization, critical thinking, metacognitive self-regulation, time and study environment, and peer learning. Moreover, females found as more positive towards chemistry and better organization and help seeking. Furthermore, interview results indicated that students in experimental group demonstrated better scientific understanding of solubility equilibrium concepts compared to those in control group.

The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach on 9th grade students’ understanding in chemical bonding concepts and their attitudes toward chemistry as a school subject compared to traditionally designed chemistry instruction. Seventy-two ninth grade students from two intact classes of chemistry course taught by same teacher in a public high school in Ankara were participated. The study was applied in the spring semester of 2011-201...
EFFECTIVENESS OF CASE-BASED LEARNING INSTRUCTION ON STUDENTS' UNDERSTANDING OF SOLUBILITY EQUILIBRIUM CONCEPTS
Cam, Aylin; Geban, Ömer (2013-01-01)
This study was conducted to investigate the effectiveness of learning activities based on case-based learning over traditionally designed chemistry instruction on eleventh grade students' understanding of solubility equilibrium. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same chemistry teacher. Each teaching method was randomly assigned as control and experimental group. The experimental group received case-based learnin...
