INTERACTIVE LANGUAGE TEACHING


Interaction as the Key to Teaching Language for Communication
Students achieve facility in using a language when their attention is focused on conveying and receiving authentic messages (that is, messages that contain information of interest to speaker and listener in a situation of importance to both). This is interaction. Interaction involves not just expression of one's own ideas but comprehension of those of others. One listens to others; one responds (directly or indirectly); others listen and respond. The participants work out interpretations of meaning through this interaction, which is always understood in a context, physical or experiential, with nonverbal cues adding aspects of meaning beyond the verbal. All of these factors should be present as students learn to communicate: listening to others, talking with others, negotiating meaning in a shared context . There must be interaction between people who have something to share.

Collaborative activity of this type should be the norm from the beginning of language study.  Part of the teacher's art is to create, or stimulate student creation of, the types of situations in which interaction naturally blossoms and in which students can use for actual communication what they have been learning in a more formal fashion. In this way, they are already engaging in the central activity for which language is used in human relations.

Why is interaction so important in language-learning situations? Through interaction, students can increase their language store as they listen to or read authentic linguistic material, or even the output of their fellow students. (As teachers, we frequently overlook how much students learn from their peers.) In interaction, students can use all they possess of the language - all they have learned in real-life exchanges where expressing their real meaning is important to them. 

Student needs; course design; classroom procedures
How interaction is achieved in formal situations is a matter of technique or of classroom approach; in less formal situations it involves imaginative planning with student input. In either case, the teacher has a number of options. How can teachers select from this great variety of proposed approaches and techniques? What kinds of guidelines can they follow?

First, in all teaching, comes the student. The teacher needs to consider the age of the students, their scholastic background, their culturally absorbed ways of learning, and their objectives in studying the language that are largely determining their motivation. Only after such matters have been taken into account and decisions made about the kind of course   that will meet the students' needs in their particular situation will teachers begin to reflect on appropriate ways of selecting and presenting material .  Thus,  that the objectives of the students may be achieved.

Furthermore, each teacher has a personality to express.  Teachers are individuals who teach and interact most effectively when what they are doing conforms to what they feel most comfortable doing. Teachers should not be looking for the one best method for teaching languages or helping students learn languages, but rather the most appropriate approach, design of materials, or set of procedures in a particular case.  Teachers need to be flexible, with a repertoire of techniques they can employ as circumstances dictate, while keeping interaction central  -  interaction between teacher and student, student and teacher, student and student, student and authors of texts, and student and the community that speaks the language. 

Comprehension and expression 
Whether in oral or graphic form, comprehension and expression of meaning are in constant interaction in real-life communication. Some scholars maintain that all that  is needed for students to acquire language is plenty of comprehensible input, and "the ability to speak (or write) fluently in a second language will come on its own with time" (Krashen and Terrell 1983: 32); in other words, after a great deal of listening, speech will emerge spontaneously in a natural order. Intensive listening alone will not lead to fluent and effective production of utterances. Listening draws on knowledge of the world and expectations   aroused by the situation and by the persons involved in it. Listeners have little control over the speech to which they are listening. In interpreting what they are hearing, listeners are guided by the rhythmic segmentation of the speech by the speaker and the sequence of semantic element.  If we are cultivating effective listening skills, we teach students to rely on semantic cues and NOT to focus on the syntax. What is said here about listening can be applied equally to reading. Fluent readers draw on semantic cues. 

On the other hand, speaking begins with the intention of the speaker. Unlike the listener, the speaker controls the level of language and the elaborated or simplified form  that will be used. Consequently language learners, when speaking, can keep within a simplified syntax and reduced vocabulary to express their meaning. 

Speakers need grammar to express their meaning with any precision and to retain the listener's respect and attention. Listeners, on the other hand, may bypass much of the grammar by resorting to semantic strategies. This is the fundamental difference between listening and speaking.  Because of this difference, neither alone can lead to the other in some incidental, subconscious, unfocused way. Even with attentive, focused listening, the listener is paying close attention to details of the content and the development of thought rather than to specific elements of syntax, except where there is ambiguity or unclear meaning. The same thing happens with attentive reading, which is why proof-reading is so difficult.

Promoting interaction
To promote interaction, individuals (teachers as well as students) must appreciate the uniqueness of other individuals with their special needs - not manipulating or directing them or deciding  how they can or will learn, but encouraging them and drawing them out (educating), and building up their confidence and enjoyment in what they are doing. Teacher-directed and -dominated classrooms cannot, by their nature, be interactive classrooms, and this is what language teachers need to learn. Interaction can be two-way, three-way, or four-way, but never one-way.

Interactive language teaching requires a high degree of indirect leadership, along with emotional maturity, perceptiveness, and sensitivity to the feelings of others. When a teacher demonstrates these qualities, students lose their fear of embarrassment and are willing to try to express themselves. Once students feel appreciated and valued, they are anxious to show what they can do, to propose and participate in activities.

Whatever promotes student participation in a relaxed and enthusiastic atmosphere stimulates the interaction that is essential to successful language learning. The interaction may be quiet; it may be noisy; it may be alert and dynamic.The interaction can take place in large groups, small groups, or pairs, but it will be there, with students deeply involved in tasks and activities that draw on their creativity.

What happens in an interactive classroom?
1.  In an interactive classroom there will be, first of all, much listening to authentic materials ,  with no prohibition or discouragement of spoken response or student-initiated contribution. The listening will be purposeful as students prepare to use what they have heard in some way. Authentic materials include teacher talk when the teacher is fluent in the language. When teachers cannot provide this kind of input, they will rely heavily on audio and video tapes or, for reading, on written texts. Authentic materials need not be difficult materials. These materials will always be used in some productive activity, e.g., as input for a small-group discussion or debate about controversial or unexpected elements. 
2.  Students from the beginning listen and speak  in reacting to pictures and objects, in role plays, through acting out, and in discussion. They argue about events and positions taken and share points of view.
3.  Students are involved in joint tasks: purposeful activity.  They work together doing or making things, all the time using the language as they concentrate on the task.
4.  Students watch films and videotapes of native speakers interacting. They observe nonverbal behavior and the types of exclamations and fill-in expressions that are used. They also learn how people initiate and sustain a conversational exchange, how they negotiate meaning, and how they terminate an interactive episode. Varieties of language, stress, and intonation can also be acquired and practiced in this type of activity.
5.  Pronunciation may be improved interactively not only while listening and speaking conversationally, but also in poetry reading and creation.
6. If reading  is  the activity, there should be lively interaction  of reader and text -  interpretation, expansion,  discussing alternative possibilities or other conclusions. Often reading leads to creative production in speech or writing, as students are inspired to write similar texts.
7.  What is written should be something that will be read by somebody, as with a group composition  or an item in a class newspaper  or on a bulletin board. Dialogue journals   are an excellent example of interactive writing. Students write to the teacher or to each other, and the reader responds with a fu rther message, thus combining reading and writing in a purposeful activity. 
8.  Interaction does not preclude the learning of the grammatical system of the language. We interact better if we can understand and express nuances of meaning that require careful syntactic choices. Learning grammar, however, is not listening to expositions of rules but rather inductively developing rules from living language material and then performing rules  (Rivers 1981: 194-6). This process can and should be interactive, with students internalizing rules through experience of their effectiveness in expressing essential meanings. Many activities can be developed where students use particular structures without feeling they are learning grammar.
9. Testing too should be interactive and proficiency-oriented, rather than a sterile, taxonomic process. Students should be put in situations where they hear and react to real uses of language or where what they read is to be incorporated into some further language-using activity. 

Turn-taking mechanism
(Kramsch, 1987, pp 22- 27)

Control of turn-taking mechanism is important for effective classroom interaction. In teacher-oriented interaction, the teacher selects the next speaker and automatically selects him- or herself for the succeeding turn. There is little motivation for students to listen to one another, and the only motivation to listen to the teacher is the fear of being caught short on an answer. Teaching students how to take turns, as easy as this might seem, requires teaching a number of skills that are not automatically transferred from the mother tongue. Students must learn to listen to the utterance of the previous speaker across its delivery, process it as it is spoken, interpret it, create and formulate a reply as they listen, find a natural completion point in the speaker's discourse, and take the floor at the appropriate moment. This requires a  concentration and combination of listening and speaking skills that need
to be practiced.

In group-oriented interaction, the teacher should systematically encourage the students to take control of the turn-taking mechanism by adopting some of the features of natural discourse
   Tolerate silences; refrain from filling the gaps between turns. This will put pressure on students to initiate turns.
   Direct your gaze to any potential addressee of a student's utterance; do not assume that you are the next speaker and the student's exclusive addressee.
   Teach the students floor-taking gambits; do not grant the floor.
   Encourage students to sustain their speech beyond one or two sentences and to take longer turns; do not use a student's short utterance as a springboard for your own lengthy turn.
   Extend your exchanges with individual students to include clarification of the speaker's intentions and your understanding of them; do not cut off an exchange too soon to pass on to another student.
By moving toward more group-controlled forms of turn-taking, classroom interaction also gives the group more practice in the management of topics.

Examples of Activities to promote interaction
Decoding of a text
A reading has been assigned overnight as individual homework. Students sit in a circle; the teacher acts as recording secretary. The group brain-storms lexical items they find important toward nderstanding the story (time limit: four minutes). Students can take the floor if and when they wish; the teacher writes all contributions on the board in their correct form, without evaluating them. During the time allotted, the students are in total control of the discourse. After the brainstorming, the teacher suggests linking the separate items to make coherent "islands of under-standing." The students again take over and suggest which items can be linked in which way. The teacher draws the links on the board and recapitulates at the end the suggestions made.

Face-Saving Gambits
The teacher explicitly sensitizes  the students to the routine of group conversation and the mechanics of perceived fluency: appropriate ways of opening and closing conversation, and polite ways of interrupting, making a request, or making a negative comment. Three or four alternative gambits are written on the board, such as "I have a question.", "May I ask a question?",. "May I interrupt for a second?", "I would like to ask something." The group repeats these to practice appropriate intonation. The students then practice them individually by addressing the teacher or a fellow student as opportunity arises within the limits of the lesson.

Peer observation of discourse
Three or four students lead a five-minute debate on a topic of their choice in front of the class. One-third of the class observes the turn-taking routine, one-third the way the topic is steered from speaker to speaker, and the other third the way in which errors or misunderstandings are repaired and how. Instructor and students then
conduct a fifteen-to twenty-minute debriefing.

Finding key sentence 
Pairs of students are assigned  the same paragraph of a given text. They have to read it silently, check each other's understanding, and agree on and underline one key sentence that best conveys the intent of the passage. Comparison and justification of the underlined sentences among the groups serve as a basis for a whole class interpretation of the paragraph

Conclusion   
Language learning and teaching can be an exciting and refreshing interval in the day for students and teacher. There are so many possible ways of stimulating communicative interaction, yet, there are still classrooms where language learning is tedious. Grammar rules are explained and practiced; vocabulary and paradigms are learned by heart and  tested  out  of context. As teachers, we need to set up classrooms where students are comprehending, communicating, and creating language that is meaningful, even original and stimulating. In these classrooms students are interacting in the language.
