3. Managing Problem Behaviour : Two types of behaviour is seen in the classroom viz undesired behaviour and problematic behaviour. Operant conditioning is a behaviour therapy technique that shape students behaviour. For this teacher should admit positive contingencies like praise, encouragement etc. for learning. One should not admit negative contingencies. Example punishment student will runaway from the dull and dreary classes – escape stimulation. 4 Dealing with anxieties through conditioning : Through conditioning fear, anxieties, prejudices, attitudes, perceptual meaning develops. Examples of anxiety are signals on the road, siren blown during wartime, child receiving painful injection from a doctor. Anxiety is a generalized fear response. To break the habits of fear, a teacher should use desensitization techniques. Initially teacher should provide very weak form of conditioned stimulus. Gradually the strength of stimulus should be increased.
