Control is the basic element in experimentation. Subjects constituting the control group do not receive the drug whereas those of the experimental group do set it. These simple behaviour patterns grow more complex gradually as the individual grows in age. The answers obtained are then compiled, classified and analysed or categorised and interpreted. How much is done in the same time allowed? 0000007320 00000 n Rating scales and checklists are often used as important devices of observing and evaluating personality or behaviour traits. (c) Response variables (Dependent variables): The dependent variable is the variable that we predict will change with changes in the independent variable. For example, we want to study the effect of punishment on learning. From the description of an experiment given above it will be clear that certain condition must be borne in mind for its success: (a) We have to understand the organism and its nature fully. According to Brown and Martin, “anecdotes are descriptive accounts of episodes or occurrences in the daily life of the student.” These accounts are written out of memory of the teacher or observer. The Observational Method 3. Thus, we will be able to state with confidence, after carrying out this experiment for a few days, that the most efficient mental work is accomplished, at least for those subjects, with room temperature, say at 70° F. Another important technique of experimentation in educational psychology is the use of control-group method. The stimulus is changed and the response changes. What cannot be verified or repeated by others lack scientific validity. What do we inherit? trailer <]>> startxref 0 %%EOF 914 0 obj<>stream (i) Habit strength, the strength of association between a certain S and certain R, based on previous learning. Response variables can vary in the following ways:-. ���P��ڢ��v�� �hQAi�h���`]��μ$��˙��sNλ���߾� � �&. It may be noted that the clinical methods or “procedures are not designed to discover general behavioural trends, laws or relationships. Our immediate memory can come to our rescue and we can recall the process to a large extent. Even animals can be studied with the help of this method. Another difficulty of the method is that it may destroy the very experience or process it aims at studying. Methods of educational psychology Different types of techniques are used by researchers to collect data and conduct research studies. The clinical investigator may start with some hypothesis about the probable causes of the difficulty or troublesome behaviour. The subject may become self-conscious and may not behave naturally, which he would have done had been alone in the room. This method has universal application. From the data collected, certain deductions are made as to probable treatment. He can repeat them as often as he wants. (b) The maturation level reached by the organism must not be ignored. Meaning of Educational Psychology 2. Some of the organismic variables are following:-. The Genetic or Developmental Method. 4. Scientific results are always verifiable. x��W TSW�o�J �¢�6�Āhq����"D�%*�AAQ�} �b 3. But no laboratory has studied such a man and perhaps no laboratory will be able to do that though we may succeed in studying individually the effect of each one of the above facts. Besides, this method cannot be found useful in studying children, animals, insane people and mental defective or those who are not good at linguistic expression. 0000006227 00000 n We interfere with them and arrange them for ourselves in order to see what will happen………………………. For example, a student has been asked to answer a question. We obtain a direct knowledge of the mental experience of the individual. This back-ground should help us to arrive at some conclusions about the learning behaviour in adulthood. A hypothesis is formed on the basis of available general knowledge insight and research inferences. How is inheritance modified in childhood, adolescence and adulthood?
