The effect of the worksheets on students' achievement in chemical equilibrium

Abstract

In the present study, it is aimed to determine effects of worksheets on students' achievement on the factors affecting equilibrium. The study was carried out with a quasi-experimental design. Data were collected through chemical equilibrium concept test, semi structured interviews and unstructured observations. The sample was 44 eleventh grade students enrolled in two classes from a secondary school in Trabzon in the fall term of the 2008-2009 academic years. Interview data were analysed descriptively. Data collected from chemical equilibrium concept test were analysed by using SPSS statistical programme. On the other hand data from unstructured observations were organized and then given directly. At the end of the study, it is found that experimental group students were more successful than the control group. As a result, a number of suggestions were made about development of worksheets in other difficult concepts of chemistry.
