however, the major cause is that they lack the topical language After a few lessons, learners of English writing can master the structure a a certain type of writing, but when it comes to writing practice, the majority of learners are discouraged from the task by the lack of ideas and the vocabulary appropriate for a certain topic During the first two months of taking charge of the writing skill for the English class, the author realised that most of the students use inappropriate vocabulary for the topic given and wrong combination of words or collocation In the scope of this paper, the author attemps to suggest a method that could be considered effective in helping students improve their language input II IMPLEMENTATION A LITERATURE REVIEW The importance of vocabulary is central to English language teaching because without sufficient vocabulary learners cannot express their own ideas Wilkins (1972, pp 111–112) wrote “ while without grammar very little can be conveyed, without vocabulary nothing can be conveyed” Lewis (1993(p 89) wrote “ lexis is the core or heart of language” As learners develop greater fluency and expression in English, it is significant for them to acquire more productive vocabulary knowledge The concept of a word can be defined in various ways, but three significant aspects teachers need to be aware of and focus on are form, meaning, and use Nation (2001) stated that use involves the grammatical functions of the word or phrase, collocations that normally go with it, and finally any constraints on its use, in terms of frequency, level, and so forth Teachers teach vocabulary to build students’ knowledge of words and phrases, helping them learn any and all of these different components assists them in enhancing their English vocabulary knowledge and use Jordens , et al (1996:359) believe that vocabulary is more important than grammar because people generally use vocabulary and reduce grammar particularly when getting a message across quickly and precisely is of the utmost importance; like telegrams, panic situations or times when emotions are very high Ellis (1995:42) distinguished between comprehension and acquisition of vocabulary, Ellis asserts that the acquisition increases with the rise of the number of context in which the word appears Learner need enormous encounters with word not only to consolidate a word accrued knowledge but also master the various type of word knowledge, Schmitt (2010:36) Jack and Willy (2002, p.268) assert that there is a close relationship between vocabulary growth and the amount and variety of meaning-focused input They also stress that vocabulary learning through reading and listening is an essential strand of a language course This can be done by providing large quantities if suitably graded input, and by providing language- focused activities to support it Jack and Willy (2002, p.268) also add that spoken production of vacabulary items helps learning According to the main findings of the research into spoken communicative activities by Newton (1995), Joe (1995) and Joe, Nation, and Newton (1996), the written input to a communicative task has a major effect on what vocabulary is used and negotiated during the task Learners are able to provide useful information to each other on most of the vocabulary in a typical communicative task; that is, if someone in a group does not know a particular word, there is likely to be someone else in the group who knows something useful about it and who can communicate this information effectively As for writing tasks, Jack and Willy (2002, p.269) confirm that writing requiring the synthesis of information from several related sources could provide very favorable conditions for learning from input and strengthening this learning through generative use in written output Therefore, for any essay writing lesson, the teacher should first provide the students with sufficient vocabulary by using authentic material such as reading texts and audio/video clips, then ask the students to discuss the topic using the language from the material The final stage is to use the language again in their writing B METHODOLOGY  Subjects The subjects of the study are 27 students from class 10 English 2, Luong The Vinh Specialised High School in the school year 2016-2017 Generally speaking, all the 27 students are rather good at English However, most of them seem reluctant to write in English  Research instruments: experimental teaching, observation  Procedures Sample lesson plans Question 1: Many people say that cooking and eating at home is better for the individual and the family than eating out in restaurants or canteens Do you agree or disagree? Type of lesson: Essay writing - Integrating listening, speaking, and writing skills Level: Upper - intermediate Aims: To develop note-taking skill To practice debating skill To familiarise students with the topical language that can be used in their writing Stage Divide the students into six groups Ask students to listen to three short clips about the advantages of homecooked meals and take notes Groups 1&2 take notes on clip 1, groups 3&4 clip 2, and groups 5&6 clip Ask the students in each group to exchange their notes Ask representative from groups to come to the board and write down what they have heard Teacher give the correct answers and highlight the phrases and expressions that students should pay more attention to Children’s development Develop language skills Better grades at school/boost academic performance/the family meal setting was where children learn the most vocabulary/more words makes better readers Dramatic behavioural benefits for family meals Less likely to end up with substance abuse problems/risk-taking behaviours Better health Strong association between frequent family meals and better eating habit Instill healthy eating habits Good for your family mentally as well as physically Protective factor of dinners together: from depression to anxiety to sexual promiscuity to academic achievement to criminal behaviour Commit to sitting down and having dinner: better communication, parents are more aware of what their kids are involved in Willing to talk about their struggles and temptations Less likely to get involved in risky behaviours Making family meals a priority Stage Teacher writes the question on the board Many people say that cooking and eating at home is better for the individual and the family than eating out in restaurants or canteens Do you agree or disagree? Ask the students to work in their own group and discuss the question, using the language they have just learned Ask 2-3 students to present their ideas in front of the class Stage Ask the students to write an argumentative essay, using the language and ideas drawn from their group and class discussions Question 2: The exploration and development of safe alternatives to fossil fuels should be the most important global priority today To what extent you agree or disagree?
