摘要：The purpose of this study was to develop activities based on the 5E, which is instructional model for the constructivist view of learning, about the topic “Factors Affecting the Solubility Equilibrium” in lycee-2 chemistry curriculum and to investigate their effectiveness in real classroom environment. In the study, it was used a nonequivalent pretest-posttest control group design (Robson, 1988; Karasar, 1999). The study was conducted in a high school in the city of Trabzon. One chemistry teacher having 20 years of teaching experience and 46 students, 22 of which were in treatment group and 24 were in control group, participated in the study. While the students in the experimental group were taught by using the prepared activities, the students in the control group were taught with teacher-centered approach (teacher’s expression, question and answer, writing, etc.). Both the students’ preconceptions and achievement after the treatment were determined using the Concept Achievement Test.
