English is the most popular international language used in communications, science, business and entertainment and in many other fields.Knowing English vocabulary helps people to satisfy their needs in communication, work and entertainment.Most teachers of English agree that it is difficult for them to have successful lessons on vocabulary or communication without visual aids and students will not be easy to understand and practice if they do not have certain visual aids for every task because students do not have enough necessary vocabulary to practice.
Students have been given extra lessons so that they have more time to practice their English, especially English speaking lessons, they have been helped a lot with revision before every test.
They have even been provided with well-prepared hand-outs of the points on which they are going to be tested and told what to learn to do the tests well.
Outcomes indicated that the visual learning strategies, especially those that were more stimulant, contributed to greater academic achievement.
In Vietnam, English is considered the most important foreign language, which is taught as one of the main subjects in schools as well as in universities and is also used the most in communication among other foreign languages.
The poor English vocabulary of the Vietnamese students in general and Thuong Tin High School (TTHS) students in particular is a cause for big concern.
This study investigated why TTHS students speak and write English badly and find out how visual aids help TTHS students improve their English vocabulary retention.According to the Longman dictionary of language teaching and applied linguistics, English is used as a foreign language or a second language to communicate with foreigners who speak the English language in non-English speaking countries.The English teaching and learning at Thuong Tin High School is not very significant in terms of the students’ achievement.In many schools in cities children start learning English in grade 3.There is even a trend to learn English before elementary school as their parents believe that the English language is a useful investment for their children’s future.In spite of what they have been informed and reminded of, unexpected things have still occurred, students have not improved their achievement, and the fact that most students were not very proficient in speaking and writing tests which were shown on the report of first term.To find out which factors are important in language learning, it is necessary to have a close look at social factors as well as a number of psychological dimensions of difference.Attitudes and motivation, self-confidence, intelligence, language aptitude, and language learning strategies have also been found to have an effect on language learners’ success in their language learning (Gardner, 2001).The research project took place at Thuong Tin High School located in Thuong Tin, a town about 30 kilometres from Ha Noi Capital and has been developing very fast.English is an important and compulsory subject at almost every school in Vietnam.Thus, usually students have to learn English for at least 7 years, from grade 6 to grade 12.
