Set Induction and Reinforcement


  INTRODUCTION
Microteaching is a unique model of practice teaching. It is a viable instrument for the desired change in the teaching behavior or the behavior potential, which, in specified types of real classroom situations, tends to facilitate the achievement of specified types of objectives. The pupil-teachers trained using the microteaching instrument are expected to have a greater range of technical teaching skills to choose from for overcoming day to day classroom teaching problems.
According to G.A. Brown (1978), microteaching may be described as a scaled down teaching situation in which a teacher teaches a brief lesson to small group of pupils or fellow trainees. The lesson may last from three or four minutes to twenty minutes. In most cases about10 minutes is preferred. The small group may consist of three or four pupils or peers, or up to fifteen pupils or peers.
The lessons are usually video recorded and then viewed, discussed and analyzed by the student teacher, his supervisor and perhaps, his fellow students. The student teacher may then be given an opportunity to teach another lesson to different group of pupils and view, discuss and analyze this lesson. In in-service courses it is customary to use peer group microteaching in which each member of the group teaches the other members. After video recording the set of teaching episodes they are analyzed and discussed by the group who should, preferably, use checklists and other observation instruments to analyze the process and structure of the teaching episode.

Definition of Micro teaching

 There are no fixed definition of micro teaching has yet been given. The micro teaching approach facilitates the shaping of a teacher who is insensitive to his teaching behavior.
According to Allen and Ryan, microteaching is an idea with five essential propositions. Microteaching is a real teaching. Firstly, microteaching lessens the complexities of normal classroom teaching so that class size, scope of content and time are all reduced. Secondly, focuses on training for accomplishment of specific tasks such as practice of instructional skills, demonstration of teaching method, practice of techniques of teaching, and others. Thirdly,
Microteaching allows for the increased control of practice. The rituals of time, students, supervision, and many other factors can be manipulated and greatly expands the feedback dimensions in teaching. Immediately after teaching a brief micro-lesson, the trainee engages in critique of his classroom performance.
 ·        SKILL OF WRITING INSTRUCTIONAL OBJECT

·        SKILL OF INTRODUCING A LESSON (INDUCTION SET)

This skill is concerned with methods of preparing classes for a lesson that is pre-instructional orientation. Students practice methods of starting lessons.

·        SKILL OF ASKING QUESTION

·        SKILL OF STIMULUS VARIATION
The third skill in microteaching is skill of stimulus variation. Most people are able tolerant about the world around them via their five senses which is sight, sound, taste, touch and smell. Unfortunately, educators sometimes forget to use as many of five senses as possible. Training in the skills of stimulus variation is aimed at helping student teachers to avoid teaching styles likely to induce boredom in their pupils. A stimulus situation that changes in different ways is one of the most powerful influences in maintaining orienting activity by the pupils. Carefully structured teaching material and approaches to the subject can have an important effect here, but so can the way a teacher conducts his lesson.
Stimulus variation, in the Stanford sense, focuses mainly on the latter. Some of the things the student teacher is trained in are the use of movement in a systematic way and the avoidance of teaching from one spot, the use of gestures, and the development of verbal and non-verbal methods of focusing children's attention, the development of teaching methods other than the teacher monologue by encouraging pupil participation, the systematic use of pauses, and the controlled use of different sensory channels by switching primary modes of communication,going, for example, from the oral to the visual.
For the success of any lesson, it is essential to secure and sustain the attention of the pupils-learning is optimum when the pupils are fully attentive to the teaching-learning process. How to secure and sustain the attention is main theme of this skill. It is known on the basis of

          Psychological experiments that attention of the individual tends to shift from one stimulus toothier very quickly. It is very difficult for an individual to attend to the same stimulus for more than a few seconds. Therefore, for securing and sustaining the attention of the pupils to the lesson it is imperative to make variations in the stimulus. This is because attention is the necessary pre-requisite for learning.

The components of skill involved are:

i. Movements
ii. Gestures
iii.Change in Speech Pattern
iv. Change in Interactions Style
v. Focusing
vi. Pausing
vii. Oral-visual Switching

          The meaning and purpose of these components in the context of the skill of stimulus variation will be discussed below.

Movements
          It means that making movements from one place to another with some purpose. (For writing on the black board, to conduct experiment, to explain the chart or model, to pay attention to the pupil who is responding to some question etc.)
 Gestures
          These include movements of head, hand and body parts to arrest attention, to express emotions or to indicate shapes, sizes and movements. All these acts are performed to become more expressive.

Change in Speech Pattern  

 When the teacher wants to show emotions or to put emphasis on a particular point, sudden or radical changes in tone, volume or speed of the verbal presentation are brought out. The change in the speech pattern makes the pupils attentive and creates interest in the lesson.

Change in Interaction Style

When two or more persons communicate their views with each other, they are said to be
interacting. In the classroom the following three styles of interaction are possible:

1. Teacher ↔ Class (Teacher talks to class and vice versa)
2. Teacher ↔ Pupil (Teacher talks to pupil and vice versa)
3. Pupil ↔ Pupil (Pupil talks to pupil)
            All types of interaction should go side by side to secure and sustain pupils’ attention.

Focusing

       The teacher draws the attention of the pupils to the particular point in the lesson either by using verbal or gesture focusing. In verbal focusing the teacher makes statements like, “look here” listen to me” “note it carefully”. In gestural focusing pointing towards some object with fingers or underlining the important words on the black board.

Pausing

This means “stop talking” by the teacher for a moment. When the teacher becomes silent during teaching, it at once draws the attention of the pupils with curiosity towards the teacher. The message given at this point is easily received by the pupils.

Oral-Visual Switching

The teacher gives information to the class verbally about something. This is called oral medium. When the teacher is showing maps, charts and object without saying something, this is called visual medium. If the teacher is giving information to the pupils through any one medium (oral, visual, oral visual) for a long time, it is possible that the students may lose attention to what the teacher is conveying to them. Therefore it is essential for the teacher to change medium rapidly in order to secure and sustain pupils’ attention to what he says.
There are three types media:
 1) Oral oral – visual
            When the teacher while speaking shows objects, charts and models and explains their various parts. It is switching from oral to oral-visual.
2) Oral visual
            When the teacher while speaking, shows objects, maps, charts, globe etc. It is switching form oral to visual.
3) Visual oral – visual
When the teacher demonstrates the experiment silently and then explains the
Phenomenon with the help of charts, maps, diagram etc. This is visual-oral switching.
These devices are used interchangeably to secure and sustain pupils’ attention to the lesson. Let us use these components of the skill of stimulus variation in the following micro-lesson to attractant focus pupil’s attention.

  • SKILL OF EXPLAINING AND ILLUSTRATING WITH EXAMPLES
Explanation is a key skill. Generally, the skill of explanation is complex. Explanation is a term, which, through daily use, has acquired several meanings. For example, it can be functional, causal or sequential; and inductive or deductive.
What is explanation? Explanation is to explain or to give understanding to another person. It leads from the known to the unknown, it bridges the gap between a person’s knowledge or experience and new phenomena, and it may also aim to show the interdependence of phenomena in a general sable manner. It assists the learner to assimilate and accommodate new data or experience.

The components of skill involved
 i. Clarity
ii. Continuity
iii. Relevance to content using beginning and concluding statements
iv. Covering essential points
v. Simple
vi. Relevant and interesting examples appropriate media
vii. Use of inducts, deductive approach
An effective explanation should be simple, clear, concise and interesting.In general it should not be rambling, long or dull. However, what is to be explained may be complex and abstract. Effective explanation requires careful and sensitive planning. It requires the recognition of a number of essential characteristics when putting it into operation.

(i) Planning
(a)Establish clearly, in advance, the major point or points you wish to communicate to your pupils. These may be ideas, rules, relationships, generalization, etc.
Establish links between ideas.
(b)Obtain information from pupils about their knowledge, experience, and interest to guide your planning. Your explanation must appeal to your class.
(c)Decide the means by which explanation is likely to be effective.
(d)Be flexible. Be prepared to modify your plans in the light of feedback from pupils during the lesson. Adapt to pupil needs.
(e)Be brief. Think how much you recall after 10 minutes.

(ii) Operation
(a)Consider other skills on which Explanation partly rests (e.g. teacher liveliness) – React to your class Are
(b)Structure: introduction, elaboration, summary.
-Emphasis the main points, so that their importance is clear.
          -Show them the relationship between the main points.
-Determine (if necessary) the general principles involved.

There are 7 considerations for effective explanation:

1.Istheexplanationunderstood?
2.Doesitinterestyourclass?
3.Doesitcoverthemainelements?
4.Didyourespondtoyourpupilsunderstanding?
5.Didyouclassifytheirresponses?
6.Areillustrationsinteresting?
7.Are illustrations relevant?

We will now look a little more at the question of examples. Effective explanation relies on illustration, analogy and the use of examples. In the task below, attention should be given in particular to the last of these.

a) Examples
          These are central to teaching new ideas and to obtaining feedback as to whether the ideas have been understood. Examples may be used:

i.                      To provide concrete instances or information within the learner’s experience andunderstanding, to lead pupils to perceive common features, and to abstractgeneralizations appropriate to all the specific instances.

ii.                     To test understanding of an idea, concept or principle, it may be applied to particular situations, for example to produce examples of the general category, to determine whether a particular phenomenon is an instance of the general relationship, or to use the general principle to solve a specific problem.


b) Using Examples

 Inductive approach

It starts with examples, and infers generalization from them. The major claims are:

i. It helps students acquire skills for looking for order in an apparently pattern
less set of data.

ii. Encourages divergent and creative thinking.

Deductive approach

It states the generalization first, and applies it to a number of examples. The initial statement, even if not fully understood by students, helps to focus their attention on those aspects of examples on which teacher wishes them to concentrate. Classroom observation suggests that effective explanation often occurs when first statement of aural is followed by examples and then by a second statement of the rule, for example, clarity in establishing relationship between general rule and specific examples.
          In all cases, it is essential for the teacher to use examples which are relevant to student’s experience and interests, and their present level of understanding.

·        SKILL OF USING NON-VERBAL CLUES AND KEEPING SILENT (SUCH AS GESTURES AND MOVEMENTS)
Most teachers talk too much. Training in the use of silence and non-verbal cues is aimed at remedying this state of affairs. But it is not just a negative thing. Silence can have a powerful effect if used insightfully, and non-verbal cues can very often be more effective than verbal ones.

Non-Verbal Aspects

a) Movement
Generally, a moving object is more interesting than a stationary one. Teacher cause their teaching space purposefully. Don’t be stuck to the blackboard. Move towards the class, and amongst them. In this way, as the teacher, they can create and convey various meanings such as friendliness, firmness, hostility, anger, and pleasure. Movementcan also help to exercise students’ eyeballs and prevent them falling asleep.


 


b) Gestures and Facial Expressions
As a teacher, the way they use their hands, body and head, and the way they vary their facial expressions will also convey meaning and emphasis. Many gestures are used in communication and interpersonal contact. Think of ways in which teacher can encourage attention or positive response from students by teacher’s gestures and facial expressions.

c) Eye-contact
The eyes are crucial in conveying meaning, emotion, influencing interaction gaining and holding attention. Teacher should use their eyes purposefully, inexperienced teachers are often too nervous to look at the class. Scan the whole of the class. In general, look at students while teaching. Teacher will obtain response, control and feedback of their interest and understanding in this way.Looking in to their eyes will help to convey messages and meaning, and is an effective device for controlling class discipline.

d) Interaction

Don’t talk too much. Use strategies to encourage various interaction patterns such as T-P, P-P, T-group. Involve the pupils.

e)Switching sensory channel

Vary the stimulus between voices visual for example to hold attention.
Teacher liveliness basically involves changing patterns of stimulation of the learner, to gain and hold interest and attention. It means use of these various qualities and cues in combination, and for most people it requires practice. Teacher that have experience of teachers or lecturers, who use very few cues, rarely change facial expressions, are limited in movements and speak in a dull, flat, monotonous voice. They probably bored them. Therefore, the skills on using non-verbal are very important for students in teaching and learning.
2.6 SKILL OF REINFORCEMENT
Every responding pupil of the class needs social approval of his behavior. To satisfy this need, he is always eager to answer each question known to him. If the teacher is encouraging the pupils by statements like, “good”, that is very good and certain non-verbal expressions, as smiling, nodding the head and paying attention to the responding pupil, the pupil participation in the class is maximized. The main theme of the skill is that encouraging remarks of the teacher increases and discouraging remarks decreases the pupil-participation in the development of the learning process. Teachers are right if their ways are in accordance with the following components of the skill.

The components of skill involved are:

i. Positive Verbal Reinforcement
ii. Positive Non-Verbal Reinforcement
iii. Negative Verbal Reinforcement
iv. Negative Non-Verbal Reinforcement
v. Wrong use of Reinforcement
vi. Inappropriate use of Reinforcement

Positive -Verbal Reinforcement These are the positive comments given by the teacher on the correct response of the pupil. They are:

(i) Using words and phrases like, “good”, “very good” and “excellent”.
(ii) Repeating and rephrasing pupil’s response.
(iii) Using pupil’s idea in the development of the lesson.
(iv) Using extra-verbal cues, like “um”, “um”, “aha” to encourage pupils.
(v) Using prompts like carry on think again, to help the pupil give correct response.

Positive Non -Verbal Reinforcement

The teacher gives comments to pupils on their correct response without using words. For example, this he does by nodding the head, smiling, patting, looking attentively at the responding pupil, and writing pupil’s answer on the black boards. The teacher encourages the pupils to participate maximally in the development of the lesson.

Negative Verbal Reinforcement

The teacher gives comments on the incorrect or partially incorrect response by telling that the pupil’s response is incorrect or making sarcastic remarks like “idiots”, “stupid” and others. Such behavior of the teacher discourages pupil-participation and should not be used.

Negative Non -Verbal Reinforcement

The teacher shows his disapproval without using words. This involves, frowning, staring, and looking angrily at the responding pupil, when he gives wrong response. This type of behavior of the teacher creates fear in the minds of the pupil and decreases pupil-participation.

Wrong use of Reinforcement

This is the situation, where the teacher does not give reinforcement when the situation is demanding encouragement.

Inappropriate use of Reinforcement

This is the situation when the teacher does not encourage the pupil with respect to quality of his response. He uses same type of comment for every response.
