The aim of this study was to investigate the effects of using a 5Es learning model on the pre-service science teachers? conceptual understanding and science process skills for ?gases and gas laws?. The sample of the study consisted 49 pre-service science teachers enrolled for the ?Science Laboratory Practices-I? course within the department of science education of a Turkish state university. Through a quasi-experimental research method (pre- and post- -test research design), an experimental group was exposed to the 5Es learning model (engage-explore-explain-elaborate-evaluate) with different conceptual change methods/techniques (i.e., worksheets, computer animations, analogies and experiments). A control group was also taught through existing instruction (e.g., experiments, lecture and question?answer). Data were collected through the gas laws test and the science process skills test. The results of partial eta squared (?2) revealed large-size effects for the control (0.61) and experimental groups (0.73). The 5Es learning model was more effective than the existing instruction in overcoming the pre-service science teachers? alternative conceptions of ?gases and gas laws?, as well as in improving their science process skills. The current study recommends that the 5Es learning model be tested with a larger sample throughout a long-term teaching intervention.

Research has shown that integrated science process skills are crucial in the modern-day world. In this study, we used secondary school students enrolled in the science classes to determine the role of cooperative instructional strategy on the students integrated science process skill. Ninety-eight students participated in the study. We adopted a pre-test post-test research design in the study. The participants were grouped into two different groups for the pre-test and post-test studies. The experimental group was exposed to the cooperative instructional teaching method, while the control group was taught conventionally. Test of Integrated Science Process Skills (TISPS) was used to assess the participants integrated science process skills. An independent-samples t-test was run to determine if there were differences between the experimental and the control groups on integrated science process skills in the post-test study. The integrated science process skills increased in the experimental group (4.71 ± 4.91) than the control group (23.01 ± 4.27), a statistically significant difference of 18.68 (95% CI, 16.83 to 20.54), t (96) = 20.026, p = .001 was established. It was concluded that cooperative instructional strategy enhances students performance integrated science process skills. The study recommends that teachers should be regularly trained on the use of cooperative instructional strategies.
