Özet: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.
