Abstract
As a virtual environment, the internet provides more and more support for chemistry teaching and learning. One of the useful means to increase the understanding in teaching and learning chemistry seems to be dynamic computer models or computer simulations.
These means can help students learn better about all three levels of chemical knowledge - microscopic, macroscopic and symbolic. Dissertation project will be aimed to research on optimization and evaluation of the use of thematically selected computer simulations in chemistry teaching and learning.
We assume that the implementation of this means in chemistry lessons can promote educational situation based more on constructivist paradigm and can facilitate understanding the concepts of acid-base and redox reactions on all three levels of chemical knowledge. In the research we expect the use of a combination of research methods eg. observation, pedagogical experiment (including pre-test, post-test and retention test) in chemistry lessons at secondary school as well as exploratory methods of pedagogical research to find out the teachers'interest in teaching selected topics and their innovations through ICT implementation.
Based on the research results, we plan design pedagogical scenarios of chemistry lessons with the support of computer simulations only or in combination with the corresponding real chemical experiment (design-based research).
