Evaluating the effect of teaching chemical equilibrium based on analogy and laboratuary on students achievement

The main aim of this research is to find out the effect of analogy and laboratuary based instructions on student achievement about chemical equilibrium in comparasion with traditional instruction. Semi-experimental research method was used. The sample was composed of 65 students from a high school in Trabzon. The classes were randomly determined as two experimental groups and one control group. A concept Test, semi-structured interview and unstructured observation were used as data gathering instruments. At the end of the study a significant difference was found in favor of the laboratory group over analogy, and a significant difference was found in favor of the experimental groups over the control groups.
