THE EVALUATION STRATEGIES OF INTEGRATED SCIENCE TEACHING AND LEARNING

In educational literature we can find different definitions on evaluation. Evaluation is the pay-off of description – it is the synthesis of descriptive information and criterial information according to very strict and difficult rules (Scriven, 1975). Evaluation can be characterised as the process by which people make judgements about value and worth; evaluation is the process by which people make value judgements about things (Oliver, 2000). It is obvious that evaluation is a delicate and sensitive task. On the other hand, it is not a simple and obvious process. Usually evaluation has its formal and informal sides. The main questions are: • what is to be evaluated? • when and why evaluate? • how to evaluate? • whether the process of evaluation is fair and objective?
