Variables in the teaching-learning process

INTRODUCTION
Thus a variable may be a quantity, for example, length, that can be measured and can take different values. A variable may be a characteristic, as in interest, which can be assessed and varies from person to person. A variable may also be a concept, for example, marriage, which varies from culture to culture.

In the teaching-learning process, the variables range from the content to be transacted to the attitude of the learner. The same content can be transacted in different ways depending on the desired outcomes. Learners differ both amongst each other and within each other, for example, in terms of ability, interest in a particular discipline, etc. Teacher behaviour varies from class to class and from teacher to teacher. Of all the possibilities, the variables discussed here are:


 * The learning task
 * Learner behaviour
 * Teacher behaviour
 * Teacher personality
 * Teaching style
 * Teacher expectations
 * Teacher competence

THE LEARNING TASK
The learning task is what the teaching-learning process is intended to accomplish. It can best be assessed by the Instructional Objective. For example, when transacting content about environmental pollution, the instructional objectives can be that at the end of the lesson, the learner will define environmental pollution, state the types of environmental pollution, describe the various types of environmental pollution, state the causes of environmental pollution, ....., develop pro-environmetal behaviour. Thus, the learning task is always a variable in the teaching-learning process, depending on the developmental stage of the learner, the higher amins of education, the content chosen and so on. Also, there is a wide range of behaviour that the learner will manifest depending on the learning task or instructional objectives chosen.

LEARNER BEHAVIOUR
Learner behaviour comprises collective activities displayed by the learner. Learner behaviour is different at the point in time they begin to participate in the teaching-learning process, it varies during the process and finally, at the end of the process. For our purpose, we are concerned with entry and terminal beaviour, which are assessed by the teacher. Entry behaviour comprises the activities/responses of the learners prior to the teaching-learning process. The prior knowledge of learners, their interests, attitudes, abilities, etc make up the entry behaviour of students. Terminal behaviour comprises the activities/responses displayed by learners after the completion of the teaching-learning process. Thus the change in behaviour after the teaching-learning process will make up the terminal behaviour.

TEACHER BEHAVIOUR
According to Gagne, The essential task of the teacher is to arrange the conditions of the learner's environment so that the processes of learning will be activated, supported, enhanced, and maintained. Teacher behaviour will vary from teacher to teacher and from one learning situation to another. This variable can be broken down into various components; we are currently concerned with four.

Teacher personality
Personality has being defined in various ways. Allport's definition, one of the most comprehensive is: Personality is the dynamic organisation within the individual of those psychosocial systems that determine his unique adjustment to his environment. Personality can be said to have two aspects: social stimulus value and response value. The former detemines the influence a person's personality has on others, whether he is attractive, whether he causes others to model their behaviour on his, and so on. The latter is the manner in which others respond to a person.

The behavior of the teacher depends on his/her personality as well as on the impact it has on the learners, the way in which learners respond to him/her, thus influencing communication (verbal and non-verbal), motivation, interaction with students (both within and out of the learning situation), methods of teaching, time spent on content, etc. In bief, the teacher's personality determines the learning environment, thus determining the response of the learners, to the extent of impacting achievement, attitude, self-esteem, participation and so on.

A study by WJF Lew reviewed older studies and identified the personality traits of effective teachers. It makes for interesting reading; suggest you have a look at it:

Personality traits of effective teachers

Teaching Style
Style is a predominantly personal way of doing something, whether it is wearing clothes or writing a letter (or e-mail). Teachers also have a personal style of teaching which they carry from one learning situation to another and they also moderate their style to suit the content being transacted, for instance, teaching style in the laboratory will be different from that in the classic classroom. Teaching style is affected by the teachers' beliefs about what is good teaching, their personal preferences, personality and abilities, and the content to be transacted, as evidence in the example mentioned in the prior sentence.

Instructors develop a teaching style based on their beliefs about what constitutes good teaching, personal preferences, their abilities, and the norms of their particular discipline. Some believe classes should be teacher-centered, where

The various styles can be classified into the following broad categories:

Formal Authority
Also referred to as the 'sage on the stage' model, this style is teacher-centred with the teacher being responsible for providing the learning experience to students and students being recipients of the experience. Although students may participate (ask and answer questions, clarify doubts), their participation is not central to the teaching-learning process. For instance, a lecture.

Demonstrator or Personal Model
This is a teacher-centred model wherein the teacher demonstrates or models behaviour but student participation is then necessary for learning. The teacher expects the students to reproduce the skills demonstrated, acting as a guide or coach to ensure appropriate learning. For instance, a demonstration of an experiment to then be undertaken by students.

Facilitator
Also referred to as 'guide by the side' model, this is a student-centred style of teaching with the responsibility of learning predominantly with the learners. It involves independent learning, and collaborative learning and problem solving. Group activities are designed which need active participation by students, leading to desired learning. For instance, projects.

Delegator
In this style, the teacher delegates the responsibility of learning to individual students or groups of students, who are then entirely responsible for learning, from motivating themselves to self-evaluation during learning. The teacher acts as a mere consultant. For instance, assignments.

Teacher Expectations
According to Cooper and Goody, Teacher Expectations refer to inferences that teachers make about the future academic achievement of students...teachers respond on the basis of their existing expectations for students rather than to changes in student performance caused by sources other than the teacher. Thus, if a teacher expects a child to be able to solve mathematical problems successfully and communicates this expectation to the student, either through verbal or non-verbal communication, the chances are that the child will be able to meet the teacher's expectations; unfortunately, the reverse is also true. In this manner, the teacher's expectations become a 'self-fulfilling prophecy'.

To elaborate, generally teachers have dfferent expectations from different students in terms of behaviour and achievement. In keeping with these expectations, teachers behave differently towards these students, thus communicating their expectations to the learners. Unless the learner resists these expectations, his/her behaviour will change to be consistent with the expectations, thus reinforcing the teacher's expecatations and creating a visious cycle.

Teacher competence
The General Teaching Council for Scotland defines teacher competence as comprising: These are further elaborated as:
 * professional knowledge and understanding
 * professional skills and abilities
 * professional values and personal commitment
