In order to teach effectively and efficiently, one has to combine various elements of depiction and visualization, as well as to create emotional, imaginative and sensational linkages in the learner's mind. Visualization allows to get through to one's real, inner, and subjective emotions, sensations and images. It is sometimes said that our eyes are an interface between our brain and the outside world. A good example of putting this assumption into practice can be found in the educational packages backing up chemistry curricula at different educational levels. The multimedia software designed or code signed by the author of the article comprises either succinct printed textbooks with integral CDs, or multimedia textbooks available both on CDs and on the Internet. Each of the CD multimedia lessons contains animations and simulations of chemical processes and phenomena, dynamic and three-dimensional element and compound models, tests and problem solving tasks, as well as film sequences illus-trating chemical experiments. Not only do those films allow the user to watch respective fragments of a given experiment in close-up so as to analyze interrelationships between them, but they can also be played repeatedly, thus making the user memorize the sequence of laboratory activities or the course of industrial processes. Such presentations of experiments can help teachers and students who are, for some reasons, unable to carry them out on their own. They are also an inspiration for those willing to carry out new experiments and, above all, an aid to those looking for didactic means to explain complex questions. What is important is that all experiments presented on the CDs are only those that can be always carried out safely, successfully and economically. Their visualizations create images of the course of chemical experiments in the learner's mind, which, though no substitute for their actual replication, can still be a valuable source of knowledge. The article additionally presents the interactive board as means of creating and saving interactive educational images, a tool of interactive evaluation of knowledge and skills, a field for playing educational games, a device helping the teacher organize his work, a medium of remote teaching, and a his inspiration for carrying out and interpreting experiments.

The article describes the research in chemical education carried out in Poland and its significance for improvement of chemical education on each level, as well as for the general development of learners and their future career choices. The research was carried out in cooperation with world scientific centers through, participation of polish researchers in international conferences, organization of cyclic international meetings, carrying out many years' standing common research, and taking part by the university and PhD students in European exchange programs. Particular attention has been paid to the importance of information technology development, including for instance e-teaching. It has been proven that research in chemical education contributes to elaboration of theoretical assumptions concerning teaching processes. The results are now aimed at their application in chemistry teaching and learning efficacy improvement.

A review of current textbooks on the teaching of chemistry allows us to state that an ever-growing number of them are not only very thoroughly illustrated, but are supplemented by many didactic media. The elements supporting the textbook should be treated as unique elements added at the time that the text itself was already in existence. Quite a different teaching approach is found in the case of textbooks created from the outset with the idea of using many medial codes of presenting information and having a unitary structure with specially prepared supporting media (slides, overhead transparencies, videocassetes). In the situation where the supporting media comprise the fundamental element of the audio-visual textbook, taking over a considerable amount of its content, the preparation of the appropriate materials takes on the central role in creating the book itself. Preparation of a textbook fulfilling the above mentioned criteria encounters difficulties primary of a technical nature. The hope for overcoming them lies over more often in multimedial textbooks. Working with multimedial textbook of this type should place the student in a research situation, creating conditions for conducting independent reseach - seeking answers to posed questions and providing solutions to theoretical and practical problems. Substitution of the traditional textbook with multimedial one opens several hitherto unused avenues of action made available through the new educational technology. In Poland, multimedial textbooks have yet to be developed, which would be devoted to the teaching of chemistry at the high school and junior high school level (from 13 to 18 years) and meeting the standards of the of the curriculum. These considerations have resulted in our developing research aimed at an evaluation of the effectivness of chemistry teaching supported by multimedial programs. The latter are aimed at intellectual and manual motivation of the students through emotional engagement and the way they reinforce information retention and provide acceptable methods of systematizing information elicited by the structure of the multimedial programs themselves. In considering the resuts of our research, confirming the possibility of a considerable improvement in the effectiveness of teaching natural science subjects by means of multimedia, we undertook activities aimed at developing multimedial textbooks for the teaching of chemistry at various educational levels. This undertaking of considerable scope is initiated by the textbook Chemistry with Elements of Ecology by H. Gulińska and A. Burewicz, aimed at the high school level of teching. The textbook Chemistry with Elements of Ecology is composed of three parts (each on two CD-ROMs) and contains the following subject area groups: Part 1 - "Chemistry Fundamentals", Part 2 - "Types of Inorganic Compounds", Part 3 - "Carbon and Its Compounds"
