Learning vocabulary in an English-language classroom is a major challenge for many students as it is an essential part of foreign language learning

Conclusion
This piece of work is devoted to highlight the importance of teaching vocabulary as an essential part of language acquisition. It is true that it has been claimed a lot to develop other skills or paying attention to other skills more than doing it to vocabulary knowledge, but as it mentioned before, in the last decades, it became one of the best "hot" topics for the researchers. It is almost proved that vocabulary stands in the first place to be taught and learned. Without developing this crucial skill, no one can achieve success in language acquisition. Many learners have been facing with some problems in language learning for centuries and almost all of these problems related with vocabulary knowłedge. The core skill of the language is having a good word knowledge and leaming word structure. Although there is not any exact strategy that says it can help 100 % to teach vocabulary to the students, many researchers have conducted several ways such as multimedia, encyclopedias, websites and so on. But the researchers also mentioned that the ways or strategies would be different for different learners. It highly depends on the student, especially, to the learners' characteristics such as their age, level of education, and what kind of learner they are. Including all of these things below, before teaching vocabulary, the teacher or the learner should identify these things on the students or on themselves. The most important thing is realizing the importance of learning vocabulary, then they can act in the right way which lead them to the academic success.
Vocabulary is an important part of the English teaching process. supposed to be a very effective communicative device as it carries the highest level of importance within peoples' verbal interaction. However, language itself is not only individual lexemes put together, but it is necessary to follow a set of grammar rules to assure correct comprehension of speaker's intention. Therefore, vocabulary together with grammar rules acquisition plays significant role in foreign language teaching. The purpose of this thesis is to compare two different attitudes to language teaching methodology, which are widely used in current conditions: the grammar-translation method and communicative approach, with their reasons what is to be taught and how they influence final students' acquisition. The first part is devoted to the theoretical background of vocabulary teaching. It also resumes the principles of both examined approaches and monitors the development in language teaching area - the shift from focusing on grammatical forms which have to be memorized to the communicative function of language. Practical part was realized as an experiment in the classroom. I presented the same target language for two groups of students, using different approach for each. Experiment consists of three lesson plans for each group, followed with a test. Final results are directly confronted, and benefits of each method.
