The purpose of this study was to investigate the effect of 5E learning cycle model compared to traditional teacher-centered instruction on eleventh grade students’ conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The measuring tools were Three-tier Acids-Bases Test (TABT) and Chemistry Motivation Questionnaire (CMQ). There were two groups, which were the experimental and traditional group, consisting of 78 students. Before the implementation, the tools were administered as pre-tests to both groups and the semi-structured pre-interviews were conducted with eight students to determine students’ prior knowledge about acids-bases and motivation to learn chemistry. During the implementation, 5E learning cycle model was used in the experimental group and the traditional teacher-centered instruction was used in the traditional group throughout eight weeks. After the implementation, the tools were administered as post-tests to both groups and the semi-structured post-interviews were conducted with the same students to determine their post knowledge about acids-bases and motivation to learn chemistry. Afterwards, the data were analyzed and descriptive and inferential statistics were obtained. Based on MANCOVA results, there was a statistical significant mean difference between the groups in favor of experimental group. Similarly, the students from experimental group scored higher motivation and this difference was found to be statistically significant. The results were analyzed in terms of gender as well, and there was found no statistically significant differences between the post-test mean scores of girls and boys for the effect of the implementation on understanding of acids-bases concepts or motivation to learn. The inferential statistics results were also supported with the students interviews.

Effectiveness of 5E learning cycle model on hihg school students' understanding of solubility equilibrium concept Aydemir, Nurdane; Geban, Ömer; Department of Secondary Science and Mathematics Education (2012) 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 ...
The effect of context-based instruction integrated with learning cycle model on students’ achievement and retention related to states of matter subject Sunar, Sabiha; Geban, Ömer; Department of Secondary Science and Mathematics Education (2013) This study aims to explore the effectiveness of context-based instruction integrated with learning cycle model as compared to the traditional instruction on tenth grade students’ achievement and knowledge retention on the states of matter subject and their attitudes toward chemistry. In order to achieve this aim, a quasi-experimental pre-test post-test control group research design was applied. A total of 150 tenth grade students of two high schools were the participants of the study. During the treatment, ...
Conceptual understanding of acids and bases concepts and motivation to learn chemistry DİNDAR, AYLA ÇETİN; Geban, Ömer (2017-01-01) The purpose of this study was to investigate the effect of 5E learning cycle model oriented instruction (LCMI) on 11th-grade students' conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The study, which lasted for 7 weeks, involved two groups: An experimental group (LCMI) and a control group (the traditional teacher-centered instruction [TTCI]). Based on multivariate analysis of covariance results, the LCMI students outperformed the TTCI students in terms of conc...
The effect of 5e learning cycle model on tenth grade students’ understanding in the particulate nature of matter, epistemological beliefs and views of nature of science Bektaş, Oktay; Geban, Ömer; Department of Secondary Science and Mathematics Education (2011) The purpose of this study is to probe whether there is a significant effect of 5E learning cycle model as compared to traditional instruction and gender on tenth grade students’ understanding in the particulate nature of matter concepts and their epistemological beliefs and to investigate whether there is an impact of 5E learning cycle model and traditional instruction in promoting the understanding of the nature of science. Pilot study was performed for the instruments in the between April and June 2009. T...
The effect of 5E learning cycle and multiple intelligence approach on 9th grade students’ achievement on unit of chemical properties, attitude, and motivation toward chemistry Tüysüz, Mustafa; Geban, Ömer; Department of Secondary Science and Mathematics Education (2015) The current study aimed to explore the effectiveness of based on 5E learning cycle model and Gardner's multiple intelligence theory oriented instructions students’ achievement and their retention level in unit of chemical properties concepts, attitude towards chemistry, and constructs of motivation to learn chemistry when compared with traditional instruction method on ninth grade public Anatolian high school students in Kecioren District of Ankara. The current study was intended in approximately eight week...
