The use of teaching grammar techniques by the English teacher of the 5th years “A” and “B” at Juan XXIII secondary school disables a successful teaching of English in the teaching-learning process of English as a foreign language

In the teaching-learning process of English as a foreign language, there are four skills such as speaking, writing, listening and reading, which are developed through Strategies, Methods and Techniques. We focused on teaching techniques specifically for grammar, which is the gist of the English language body and the mean to achieve performance of all English four skills.

So, we expected to find a variety of techniques he uses for teaching grammar everyday in the classroom.

Once it was considered such facts, we proceeded to apply instruments such as; observation, questionnaire and interviews in order to compilate relevant data as to different types of teaching techniques that the teacher uses in the teaching process. Our research work is quantitative designed according to the type of study we done which are exploratory and xplicative. So, we are introducing an unknown, new and a little studied issue which look for an explanation of the causes and reasons that cause the problem to be researched. Also, this research work lets carry out new researches in the four English skills. Throughout Seminary of Graduation, we dealt with several methodological steps giving th
