Mental lexicon development of natural science discourse by means of subject-oriented materials

Practical examples of the development and implementation of a system of lexical exercises in English in a specialized educational center for the formation of a mental lexicon of natural science discourse are analyzed. The author proceeds from the statement that the need to form a sustainable lexical skill is defined objectively due to the increasing requirements for school graduates. In order to create all the necessary conditions for achieving results, it is important to optimize the learning process. The system-activity approach includes the education and development of the personal qualities of students; identification of individual features of gifted schoolchildren; focus on the result of training, taking into account the conscious choice of specialized subjects; the presence of cognitive motivation among students, including the improvement of practical language skills; various forms of organization that stimulate the development of creativity; introduction to the curriculum to solve problems, necessary in future professional life. An attempt was made to find out how effective the set of certain exercises is, which, being the basis of the learning system, is characterized by scientific, communicative orientation, as well as mutual, consistency, availability of exercises and repetition of language material and speech actions at all stages of work on the lexical component of language literacy of students, particularly, the formation of the mental lexicon of natural science discourse. Gural S.K. considers discourse as a result of the synthesis of scientific thought, as a super-complex formation consisting of multi-level components that interact with each other according to certain established rules in a certain social situation. Among the basic categories of the semantic content of discourse, Gural S.K. added and analyzed another category - the mental lexicon, which contributes to the teaching of foreign-language discourse as a super-complex self-developing system. The mental lexicon is not a dictionary with a fixed number of words and data for each unit. In synergetic logic, it is an active living system where new connections are constantly being established. Synergetic means working together or interacting cooperatively. Education is a field of activity that gives schoolchildren the opportunity to learn how to use modern technology in the learning process and make an informed choice of the future profession. In the current environment, there is a need in the school education system to implement a modular course structure based on a system approach. The main reason for the growing interest in a modular systemic approach is that modern schooling does not fully meet the needs of the individual and society in terms of social and personal identity, future professional flexibility. Using action-oriented approach, the learners are responsible for their own learning. The need to apply the language that emerged while fulfilling the communicative tasks makes learning process effective and the learner active. Action-oriented approach considers the learner as a social agent in classroom where learning is a social learning environment and develops linguistic and pragmatic skills besides communicative skills. The creation of social language environment where the learner will be able jointly communicate with each other in natural science environment depends on teachers' skills and knowledge. The tasks in classroom or out of classroom must interrelate the needs of the learners. This article highlights the results of the experimental preparation of modular English courses developed on the interactive educational platforms. Using course materials, teachers have the opportunity to develop gifted learners lexical skills in accordance with the individual needs, interests and abilities of senior schoolchildren. The study conducted by the author was attended by high school students of the Specialized Educational Scientific Center of NSU of a natural science profile. Control and pilot teams were organized from these senior schoolchildren. Classes in the control group were carried out according to the traditional content of foreign language instruction using Spotlight and Starlight course books. Foreign language classes in the experimental group of students were conducted using vocabulary exercises on natural science course content so that students could develop communication skills in basic activities in English and meet individual profile students' paths. The experimental educational process was built on combination of traditional and e-learning technologies. Exercises and activities which are common in vocabulary teaching / learning: word memorizing, using synonym and antonym words, deriving new words, matching words, finding-inventing word, various word games, task completion, action project realization. Based on the above, the author concludes that the integration of Action-Oriented Approach, and modular technology into the content of foreign-language education of high school students of a specialized school is justified by the new requirements of the Educational Standard for school graduates, but is also logical from the point of view of the approach aimed at developing the student's mental lexicon of natural science discourse in active, versatile and independent cognitive activity.
