Abstract
Тhis article discusses the methods and techniques for developing vocabulary in English lessons for students. Since a large vocabulary affects the effectiveness of a lesson, we focused on discussing vocabu- lary development techniques. When writing the article, the works of foreign and Kazakh scientists in this area were considered. The study used methods of analysis and synthesis, as well as questioning as an empirical study. The purpose of this article is: a) to analyze active methods that affect the effectiveness of the lesson; b) reveal the importance of vocabulary. To achieve this goal, vocabulary development meth- ods were discussed, the results of which are used to develop pupils’ English vocabulary. Working with the dictionary during the lesson significantly affects the improvement of the language skills of students. therefore, with the help of these methods, students not only develop their vocabulary, but also learn to speak and write correctly, and also increase student interest in the subject. In addition, the best practices taken increase the teacher’s creativity and it improves the quality of the lesson. This means raising the level of learning using new technologies and methods, avoiding the monotony of lessons. Key words: vocabulary, language, methods, effectiveness, development, secondary schools.
