It is argued the need to develop new pedagogical models for preparing gifted and extra-gifted students for national and international competitions in Informatics. The models in question have to be based on a common structure and be oriented towards the development of an extended set of competences specific to Informatics and Mathematics, competences which cannot be found in the national curriculum. The teaching strategies will be based mainly on simultaneous teaching, self-learning and the creation of simulated competition environments.

The contemporary teaching methodology is in a dynamic development due to the multiple socioeconomic changes, but mainly due to the rapid evolution of the technologies, which are implemented in the training process with the purpose of solving specific problems. The integration of the methods specific to the field of Chemistry with the information technologies creates new opportunities to make the teaching methodology more efficient in order to ensure the compatibility of the formed competences with the needs of the labour market. The use of quantum calculations allows the understanding of chemical processes in terms of energy efficiency. To delve into the intricacies of the radical substitution mechanism in Organic Chemistry, modern computing software in the field of Chemistry such as Gamess, Gaussian, ChemCraft, ChemBioDraw etc can be used. The use of theoretical calculations offers the possibility to study some complicated phenomena of organic nature, which arguably strengthens the pupils/students' knowledge about the probability of the chemical reaction taking place in different classes of organic compounds

The programming languages provide a number of operators, primarily for the usual mathematical operations. Usually they have associated instructions that the microprocessor can execute directly. The bitwise operators also correspond to instructions that the microprocessor has in its set, even if they do not necessarily correspond to widely known operations. Thus, using them to perform certain tasks makes the programs very fast, especially if they are used in their critical sequences. In this material we will present the syntax and the effect of these operators in the C / C ++ language and we will present relevant situations where certain problems can be solved elegantly and by c

In this article we will analyze how we can use Lifting the exponent lemma (LTE) and Hansel’s Lemma to solve Diophantine equations in mathematical contests. Firstly, we will go through the statements of the lemmas and some simple examples, and then we will show how they can be used in some recent problems.

Computational geometry problems are often encountered in programming contests. In this article we examine some problems that, traditionally, are solved using vectors. Another approach to finding solutions is proposed, less commonly found in the specialized literature.

In the article it is made an analysis of current situation in preparation of young (junior) students for participation in Informatics national and international competitions. There are identified problems of qualitative preparation and models of solutions for these problems. In the same time there are classified decisive factors in future extension of juniors preparation
