Abstract

Teachers conducting laboratory activities should acquire some knowledge and skills during their university education. The aim of this study is to determine competences of preservice teachers about preparation of solutions and use of laboratory tools. The sample of this study consists of preservice teachers in the departments of chemistry education, elementary science and elementary mathematics education. These students have to take “General Chemistry Course” and “Chemistry Laboratory ” as part of their schooling. In order to collect data, a pencil-paper test was developed. The test was given to a total of 135 preservice teachers (45 in each department). The collected data showed that although preservice teachers took laboratory courses in their schooling, they made mistakes in tasks such as calculation, preparation of solution with proper laboratory tools, taking into account states of matter in solution preparations and so forth. Based on the results, some suggestions are made.
