Özet:

In recent years, information and communication technologies have been used in the educational process, including teaching of natural sciences. It is generally assumed that these tools have positive effect on the motivation and activation of pupils. However, there has not been much research focusing on the effect these new educational means and methods might have on the learning process in pupils, the position of teachers and on the real performance of pupils. For the above mentioned reasons, the research work which is dealt with in this article aims at eliciting the efficiency, advantages and disadvantages of the use of ICT, namely PowerPoint presentations, in different components of educational process in the field of natural sciences. The research focuses not only on the creation of presentations as didactic tools, but also on finding the optimal, most purposeful and most effective way to use presentations in the educational process. The article summarizes results so far yielded by the research which includes several years of work focusing on the production of didactic presentations and on the feed back from teachers and pupils. These efforts allow defining difficulties involved in the use of presentations, offering remedies and testing all the findings in practice.
