In making the questionnaires, the researchers developed two questions in relation to main problem and solutions to decrease miscommunication between L2 learners and L1 teachers. Firstly, Richards (1976) said that one of his eight assumptions about vocabulary knowledge which is understanding the word with understanding many various meanings matched with that word. Also, various levels of propriety could be transferred in different pronunciation based on age, sex, social or economic status (Lottgen and Campoy, 1998). Trudgill (1986) found that base of linguistic similarity and differentiation concept when speaker with a different accent associate each other. Therefore, the first question aimed at seeking the main problem which are vocabulary, pronunciation and accent causes miscommunication between L2 learners and L1 teachers. Secondly, some related study was found to solve the three problems which are vocabulary, pronunciation and accent. August et al. (2005) found that vocabulary could be improved by reading and talking about books, then speaking the vocabulary after reading the story. According to Chou (2011), if the readers know more words, they will be easy to interpret what they read. Mitra et al. (2003) said children will be able to differentiate the types of accent by applying STT system. As suggested by Lashbrook et al. (2002), Universities provide studying abroad for students in order to improve their language or communication ability and get new experiences. Thus, each problem has its own solution. TO collect data efficiently, the questionnaires were designed in accordance with above supports as follows ;
