Language Use and Its Effects on Comprehensible Input in EFL Classrooms

This essay is an abridged and translated version of my another essay called "İkinci Dil Öğretiminde Hedef Dil, Ana Dili ve Araç Dil Kullanımı".

According to the dynamics of the language classrooms, we have two types of interaction: Classroom Language and Instruction Language. Although nevertheless, these concepts look similar, they differ depending upon the instructor, learner, materials, course designers or curriculum and institutional conditions or authorities, etc.

Classroom Language means the language that speaks by the individuals of the classroom inside or outside of the institution. Instruction Language, on the other hand, comprises the language that speaks by the instructor to provide the input of the target language. For instance, even the instructor uses the target language while the language teaching process, it is quite possible to see the usage of another common language between the learners in reality. In this sense, we can classify the language choices in three main sets of factors: Target Language, Medium Language, and First Language.

  1. Target Language Usage:

Using the target language as a classroom language or an instruction language might have an important role on creating a real communication environment and supporting productiveness of the learners, especially given the fact that there may be few opportunities for learners to encounter aforesaid atmosphere outside of class settings (Hall, 2001; Halliwell and Jones, 1991; Macoro, 2000; Macdonald, 1993 as cited in DiFrancesco, 2013).  However, when it comes to applying this when and how the main determiners consist of the strategies selected in reference to the classroom dynamics. Concordantly, we can specify the implementations for the target language use as follows:

  • The instructor can use the techniques of Total Physical Response by concreting objects, visuals, gestures, facial expressions, and body language.
  • The instructor can fill the silent moments with talking in a target language environment. For instance, technical issues can be verbalized in the target language to show the actions that can possibly occur in the natural and real world’s situation of the target language.
  • To check comprehension, instructors and learners can develop specific gestures or codes between them. For example, they can try to understand each other by acting out or drawing.
  • The instructor can also teach grammar in the target language by making form-meaning connections. Usage of visual material such as animations or presentational softwares might be helpful on this.
  • Leaners should be thought simple language phrases or questions to interact in the target language during class sessions. The instructor can provide these expressions in posters or colored cards as an easy reference for learners during the activities.
  • Learners should be aware that they do not have to understand every word they heard, instead of that, they can try to catch the keywords and form a guess as to the overall meaning (DiFrancesco, 2013).

2.First Language Usage:

Using the first language in the foreign language teaching process has many different reasons for instructors and learners. While instructors are using the first language to explaining grammatical or complex structures, learners choose to use the first language for communicating and enlightening the meaning. However, besides all, first language usage comes to easier than other options for both of them. The first language is actually can be helpful for second language acquisition as long as it is using fairly balanced.

In the US, researches have shown that instructors utilize English for discipline and classroom management, grammar explanations, clarification, saving time and avoiding ambiguity (Duff and Polio,1990; Kraemer, 2006; Wing, 1980 as cited in DiFrancesco, 2013). According to the Common European Framework of Reference for Languages, the first language can be used for classroom management and explanations, however when it comes to implementing activities, presentations and exercises, target language should be used. Nevertheless, first language usage should be gradually decreased and the ways that would increase self-studying must be augmented by adding verbal and written authentic materials to the curriculum (MEB, 2002). The factors that would provide an effective way for first language use can be explained as follows:

  • Instructors can use the first language to arouse a sense of security in learners.
  • They can build background prior to reading, listening, speaking and writing tasks and activities by using the first language.
  • They can give some comparative and typological examples between the grammatical features of first and target languages.
  • Instructors can maximize intake by using L1 to make the input comprehensible.
  • They can use the mother tongue to avoid giving learners the feeling of identity-threatened by the total rejection of their mother tongue.
  • They can help the students with comprehension problems when L2 fails or is not effective enough (Ostovar – Namaghi and Norouzi, 2015).

3.Medium Language Usage:

We can describe the medium language as the common language between learners and the instructor inside or outside of the classroom. Medium language helps to explain oneself and easies comprehension.

According to Brufit (2001), wherever there are social differences, it reflects the language (as cited in Futurelearn, 2017). For this reason, if the classroom has students from different cultural backgrounds, medium language usage might have an important role. We can assume intercultural communication skills significant as much as the four main language skills for multicultural classrooms. Because language teaching should be more than teaching grammar and vocabulary and consequently the acquisition of the target language’s culture is part of the learning process.

Teaching cultural dimensions have been always problematic for foreign language teaching. In that case, what is the point that makes culture essential for EFL settings? In second language teaching, it progresses naturally. Even a special effort, the learner can discover the target society’s cultural believes, values and behaviors. Beside of this, second language teaching classes has a broad range of cultures in case of international classroom profiles. Therefore, the learner’s international communication skills are not limited by only the target culture. For this reason, provide an intercultural awareness in the classroom needs the effort of the instructor in EFL settings.

If the foreign language teacher uses a common language as a medium of the instruction, she/he must be considered the factors as follows:

  • Every learner has a different learning style.
  • Cultural patterns might be identical for the groups, in this case, interruptions can be tolerated, and some of the students can be shy to ask questions.
  •  The instructor should have some typological information about the target language and the medium language to compare.
  • The medium language can increase the metacognitive skills between the learners, it also can make easier to discover the target language.

According to Krashen (1985) understanding messages is the only way to learn a language which means receiving comprehensible input. From this point of view, we can talk about different interactions that are possible to see occurring the target language usage, first language usage, and medium language usage. For instance, when we think of an EFL classroom in Turkey, target language usage must contain some syntactic dimensions. On this point, it is quite possible to come across a complaint from the learners such as “I can understand but cannot speak!”. Understanding without speaking shows us the level of comprehension stuck on the semantic state. Therefore, the instructor would be careful about not just the comprehension of the input, also the output. If we take on the hand the same classroom again if the instructor chooses to use the first language in a fair amount. This might help to compare Turkish linguistic features with English which also called inter-language grammar (Gass,1997). The acquisition of inter-language grammar helps the learners to evaluate the input to output.  Besides of all, there is also another point which possible to come across in EFL settings is miscommunication. It can be seen as “misunderstanding” or “half understanding”. These kinds of situations are another important reason to identify language usage in EFL classrooms.

When we considered all these together, it is obvious to take separately Classroom Language and Instruction Language, when it comes to choosing the language in use. However, a “fair amount of usage” can confuse methodologically the instructions and also it gives them a free space to designing their lessons by considering classroom’s dynamics. When these dimensions absorbed properly, the appropriate language use must be chosen for comprehensible input and consequently output.
