Chemical models are indispensable tool in chemistry class and enable secondary school pupils to develop complex thought processes and spatial concepts, both of which are necessary to improve their understanding of chemical concepts. In this research, special emphasis is given to complex competencies not only their acquisition, but rather how pupils develop them. For this purpose, a learning strategy has been developed, called learning by self-generating chemical models. Pupils learn individually on their own models, which are made from easily accessible, low-cost materials. The impact of workable models was investigated (assembly of commercial models and production of self-made models) on the (1) learning success using simple molecule shapes and (2) the degree of competence development which realized through the implemented activities. The study involved first-year secondary school-pupils, defined as self-creators of paper- and -wire models (experimental group) and assemblers of commercial models (called the control group). The appearance of the molecules being studied took the form of geometric shapes and structures, which pupils present by making of ball-, called wire-models from plasticine and wire or paper created, called paper models. Based on the results of statistical processing of the data, we found that self-creation of models (as an innovative approach) leads to better understanding and to subsequently sustained knowledge for the pupil. It should also be noted that pupils who were self-generators in comparisons to those who merely assembled the models, generally developed many complex skills in the areas of problem solving, practical competence, mathematical competence and critical thinking skills. The knowledge so acquired was also better understood. Key words: chemical models, competencies, self-made models, teaching and learning by models.

This study is focused on the curricular innovations of methodological subjects for acquiring of teachers competences at undergraduate education where students as prospective chemistry teachers serve as a goal group. The redesign of the curricular forms thus introduced (such as Lectures, Seminars, Didactic /Laboratory Practical Courses and Mentor work) is based on consistent consideration of topical didactic principles. Research into the optimal forms for curriculum performance focuses particularly on their organisation, methodology and evaluation. These three model parameters serve to implement student activity and autonomy, goal-oriented process learning and democratic relations to ensure realisation of the competences necessary for carrying out the teaching and learning model. The active development and acquisition of subject didactic competences is accompanied by three issues: “What? How? Why? and the following infinitives: “to preserve, to innovate and to abandon”. Key words: teaching skills and competences, student autonomy, didactic principles, curricular forms of methodological programme.

The methodical approach presents the proposals of didactic-methodological planning of curriculum password "Fields in the periodic system" for the needs of the key components of teaching & learning process. The didactic-methodological proposal of each of the current macro-didactic components of the learning process includes the following didactic elements: chemical terms, method / method’s password, didactic tool, didactic material. For each macro-didactic component, it is planned to use one of the methods from the author's "methodic hexaplet", defined by the didactic formula ADDGPS: Analogy-Drama-Dance-Game-Pantomime-Socratic dialogue. The dance method is used to acquire the concepts of atomic orbitals and electronic configurations of the elements. The macro-component repeating involves the role-play method used to implement the Expeditionary Visit of PTE by using the Identity card of the element. Both methods of quiz conversation method according to Socrates and the Small PTE cells are used for evaluation. The use of all the mentioned methods is evaluated in terms of the competencies that must be mastered by the teacher, as well as the competencies that the student acquires when performing an individual method. Keywords: Periodic table of elements; chemical terms; ADDGPS methods (Analogy-Drama–Dance-Game-Pantomime-Socratic dialogue)

The main aim of the teacher study program is to ensure the proper role of teaching practice, which is included in initial teacher training courses. It is necessary that teachers of chemistry gain or develop learner competencies for appropriate teaching/ learning in the chemistry subject by using innovative teaching methods. In terms of activities and methods correction of the continuous teaching practice model for prospective chemistry teachers in Pedagogical study program of 2nd degree "Educational Chemistry" which would ensure the creation of a competent chemistry teacher (active and innovative).The main result of the study is a list of potential competencies by prospective chemistry teachers using innovative teaching methods. These competencies can be developed and produced in the performance of activities defined by using continuous teaching practice, particularly in the areas of testing and assessment, experiential and collaborative learning, and experimental (laboratory and field) work. Each of these components is separately assessed by activity and competence. Key words: continuous teaching practice (role), innovative teaching methods, learners’ competencies, potential competencies by prospective chemistry teachers.
