             INFORMATION PROCESSING FAMILY

Introduction

Teaching models prescribe tested steps and procedures to effectively generate desired outcomes. The number of emerging models and the ones that have emerged is uncountable. Each emerging new model either explores a new approach or attempts a modification of the conventional ones as to cater the uniqueness of individuals. Most importantly, any teaching model should optimize learning experiences to the needs of each learner by carefully exploring the learning problems and offering tailored assistance.


Information processing models
                 This model has especially been prepared for teacher education. Here, pupil teacher analyses learning problems and reaches the solution one by one. Information processing refers to the way people handle stimuli from environment, organize data, sense problems, generate concepts and solutions to problems and employ verbal and non-verbal symbols. Some information models are concerned with ability of the learner to solve problems and thus emphasize productive thinking, others are concerned with general intellectual ability.


Focus
          The model aims at developing social processes and making he principles understood by learners. In order to achieve these activities special emphasis is given on the comprehension of facts, events, laws and principles.

Syntax
          Situations are created by the teacher here to develop interactive activities. For this purpose teaching activities are arranged in such a manner that pupils understand the concepts very easily.
E.g.
1. List of teaching activities are prepared.
2. These activities are classified into different groups
3. then these teaching activities are exposed before the students one by one
4. Then direction of teaching activities is determined.
5. The directions and relations of various teaching activities are explained.
6. Then conclusions are drawn on the basis of these explanations.
7. Then in order to test the consequence of these activities, hypothesis is forulated.
8. Then these hypotheses are explained. For this purpose, help is taken from facts and relevant concepts.
9. Then hypotheses are verified and generalization is arrived at.
10.Finally, conclusions are practiced.
In this way, the pupils come to understand facts and concepts very clearly.

Social System
          Here students are given full freedom to act in the class. Teacher also initiates his activities from the activities of the students. He works in the class only as a guide or helper. Questions are continuously asked in the class in order to maintain democratic environment.

Support System
          Only objective type test is used here to evaluate the comprehension ability and intellectual power of students.


Types of information processing model:
1. Inductive thinking
2. Concept Attainment model
3. Synectics model
4. Advance Organizer model
5. Scientific Inquiry Method


INDUCTIVE THINKING
         The ability to create concepts is generally regarded as one of the basic thinking skills. The model presented here is from the work of Hilda Taba names for concepts; and to explore ways of becoming more skillful at discovering and organizing information and at creating and testing hypotheses describing relationships among sets of data. The model has been used in a wide variety of curriculum areas and with students of all ages.

CONCEPT ATTAINMENT
            This model, built around the studies of thinking conducted by Bruner, Goodnow, and Austin (1967). It is designed to help students learn concepts for organizing information and to help them become more effective at learning concepts. It includes an efficient method for presenting organized information from a wide range of areas of study to students of every stage of development.

SYNECTICS MODEL:
                    Synectics is interesting new approach to the development of creativity designed by William J.J. Gordon and his associates. Synectics derived from Greek word mean “the joining together of different and apparently irrelevant elements”. Synectics theory applies to the integration of diverse individuals into a problem stating and problem solving group. Synectics defines creative process as the mental activity in problem stating and problem solving situations where artistic or technical inventions are the result.

ADVANCE ORGANIZERS
                        During the last twenty years this model, formulated by David Ausubel (1963), has become one of the most researched in the information-processing family. It is designed to provide students with a cognitive structure for comprehending material presented through lectures, readings, and other media. It has been employed with almost every conceivable content and with students of every age. It can be easily combined with other models-for example, when presentations are mixed with inductive activity.

CONCEPT ATTAINMENT MODEL (CAM)
                         CAM was developed by J.S.Bruner, J.Goodrow and George Austine in 1956.The model emerged out of the study of thinking process in human beings. It is based on the assertion that a human being is endowed with the capacity to discriminate and to categorize things in groups. This model is used for teaching concepts to the students. It enables them to understand fully the similarities and relationship among various things of the environment.


         



              CONCEPT ATTAINMENT MODEL IN
                         TERMS OF ELEMENTS

Focus:  The main focus of the model is to develop inductive reasoning of the students. Bruner and his associates orient their work for the description of a process by which the
Students discriminate the attribute of the things, persons, events and place them into categories. The students are also taught about the concept which is of great use to them in order to live successfully in different life situations.
Syntax
 Structure of the model has the following four phases.
 Presentation of data
 Analysis of hypothesis
 Formation of hypothesis
 Teacher reaction
 Rejection or confirmation of hypothesis
 Closure
 Practice

Principle of reaction
 Immediate check of wrong answers and acceptance of right answers is a must.

Social System
The teaching situation is moderately structured. The teacher has to control all actions of the class-room, but reasonable freedom is given for discussion within different phases of teaching.

Support system
The lessons require concepts which can be arranged so that concept may be drawn from the material.
Application
 Concept attainment model is very useful in teaching the concepts through inductive reasoning.
Merits of concept attainment model
1.      It is a natural way of teaching and learning.
2.      It is helpful in developing the power of imagination of the students.
3.      It helps in the development of reasoning power of the students.
4.      It help students to analyse things systematically.
5.      It keeps students actively engaged in the classroom activity
6.      It helps in making the student good observers.
7.      It encourages the habit of self study in the students.
8.      It helps the learners to apply their knowledge in different situations.
9.      It keeps the student busy in the classroom work.
Limitations
1.      It makes high demand on the students as well as teachers.
2.      All the students of the class may not be able to participate in the teaching-learning process
3.      Some students, on account of their shyness, fail to derive the requisite advantage of this model.

Illustration
Topic: Concept of ‘proper noun’
Eg: Delhi – yes     book – no (one positive and one negative example)
Mysore – yes        pencil – no

Effective use of the model
To be done in small groups. This facilitates involvement of all students. But before dividing into groups steps to be followed should be oriented it one leader in each group. The teacher to visit and guide them. At the end all groups to meet together.



                               SCIENTIFIC INQUIRY MODEL

It was built by J. Richard Suchman for developing scientific inquiry training skills in the students. This model is based on the following beliefs of Suchman.
1.  All knowledge is tentative. A scientist generates a theory of principles. After sometime it may be pushed aside by a new one.
2.  Most of the  problems are amenable to several equally plausible explanations. There is no one particular answer to a problem.
3.  Inquiry is natural. All of us often inquire when confronted with a problematic situation or puzzle.
4.   An individual can be made amenable to the process of inquiry. He can be made to learn to analyse his thinking strategies.
5.   In addition to what is already known to an individual, he may be taught the new strategies to enquire and explore things.
6.   The inquiry process is co-operative effort. It is always facilitated by the ‘give’ and take of ideas from colleagues.

Focus
Children are curious by nature and this model attempts to satisfy their urge of curiosity by providing systematic training in inquiry.


Syntax
It consists of five phases:
Phase one: Encounter with the problem
1.  Explaining inquiry procedures.
2.  Presentation of the problem or puzzled event.
Phase two: Data gathering process (verification)
1.  Verifying the nature of objective and conditions.
2.   Verifying the occurrence of the problem.
Phase three: data gathering process (experimentation)
1.  Isolating relevant variables
2.  Hypothesizing and testing casual relationships.
Phase four
 Organizing, formulating an Explanation
   Formulate rules or Explanations.

Phase five
 analysis of the enquiry process
Analyze inquiry strategy and develop more effective ones.


Principles of reaction
According to Joyce and Wil (1978) the responding and reacting may be guided by the following:
1.      Framing questions in such a way that the answers can be given in ‘yes’ or ‘no’.
2.      Asking students to rephrase questions properly.
3.      Pointing out unvalidated statements like, “We have not yet established that this is solid.”
4.      Using the language of the inquiry process.
5.      Providing free intellectual environment to the students.
6.      Pressing students to make clear statements of their theories and more support for their generalizations.
7.      Encouraging interaction among students.

Social system
          The inquiry training model can be highly structured, with the teacher controlling the interaction and prescribing the inquiry procedure. The norms of inquiry are cooperation, intellectual freedom, and equality. Interaction among students should be encouraged.  At every stage, the teacher is expected  to respond in such a way as students may be encouraged to initiate and pursue the inquiry.


Support System
          Both the students and the teachers need additional support. The teacher provides support to the student to develop material. He himself requires support in the form of a set of confronting materials, technical understanding of the intellectual processes and strategies of inquiry and resource material bearing on the problem.
Application Context
          This method is designed to provide training to solve the problem in a systematic way. As observed by Weil and Joyce, “the emphasis in this model is clearly on becoming aware of and mastering the enquiry process, not on the content and explanation of any particular problem situation. Although the model should also be enormously appealing and effective as a model of acquiring and using information, the teacher cannot be too concerned with subject matter coverage or correctness.”
Merits of inquiry teaching model
1.      It helps in development of imagination power of students.
2.      It gives training to analyse things systematically.
3.      It helps in development of reasoning power.
4.      It provides a lot of training to students to put suitable questions.
5.      It imparts training to the students to go deep into the problem.
6.      It prepares the students for solving various problems of life systematically.
7.      It engages the continuous attention of the teacher as well as the students
8.      Students hardly can afford to be absent minded.
Limitations
1.      The model can work well only in the hands of very intelligent and resourceful teachers.
2.      An average teacher can hardly make use of this model.
3.      Shy students lag behind.
4.      It puts a lot of premium on the speaking ability of the students.

Example

It happened about thousand years ago. A battle was fought between he armies of two kings. King A had a very large army as compared with King B. king B himself commanded the army. His army included trained horses. There was a unit of fighting elephants in the army of King A. in the beginning, the army of King A had an upper hand. The day became cloudy. It began to rain. The ground became slippery. There was lightning in the sky. There was a strong storm. In spite of initial gains, King A lost the battle.
          Interaction in the class to find out the reason of the defeat of King a may take the following form:
Student 1: was the army of King A not adequately equipped with weapons?
Teacher: No
Student 2: was the army not well-trained?
Teacher: No
Student 3: were there dissentions in the army?
Teacher: no
Student 4: Was the food supply short?
Teacher: no
Student 5: can the elephants fight on a rainy day with the same strength and tactics as on an ordinary day?
Teacher: no
Student 6: can we compare the fighting spirit of the two armies – one commanded by a brave king and the other by a commander
Teacher: yes
Student 7: will not the army commanded by a brave king show more zeal?
Teacher: yes

In this way students can be given inquiry training.



                  


                     SYNECTICS MODEL
       
                      Synectics is interesting new approach to the development of creativity designed by William J.J. Gordon and his associates. Synectics derived from Greek word mean “the joining together of different and apparently irrelevant elements”. Synectics theory applies to the integration of diverse individuals into a problem stating and problem solving group. Synectics defines creative process as the mental activity in problem stating and problem solvingsituations where artistic or technical inventions are the result.
Characteristics of  Gordon’s Model 
* According to this model creativity is important in everyday activities. Gordon’s model is designed to increase problem solving , creative expression , empathy and insight into social relations.
*Second, the creative process is not at all mysterious . It can be described, and it is possible to train persons directly to increase their creativity. (Traditionally creativity is viewed as a mysterious innate and personal capacity)
*Third , creative invention is similar in all fields- the arts, the sciences, engineering and is characterized by the same underlying intellectual processes.
*Gordon’s fourth  assumption is that individual and group invention (creative thinking ) are very similar .Individuals and groups generate ideas and products in much the same fashion.
In school systems the main technique used is analogy. The child is lead into an  ‘imaginary/ illogical world’ to see things never seen before to express himself in novel ways, to approach problems from a different angle which is entirely different from others as is perceived by the mind’s eye through ‘fresh ways of thinking’. He has to express his ideas clearly and also grasp ideas clearly and comprehensively.

Syntax:
Steps of the Model to be followed in the Classroom
1. Describe the topic
2. Create direct analogies
3. Describe personal analogies
4. Identify compressed conflicts
5. Create new direct analogy
6. Re-examine the original topic
7.Evaluate
Social System:
          The model is moderately structure, with the teacher initiating the sequence and guiding the use of the operational mechanisms. He also helps the students intellectualize their mental processes. The students have freedom in their open-ended discussion as the engage in metaphorical problem solving. Norms of co-operation ‘platy of fancy’ and intellectual and emotional equality are essential to establishing the setting fro creative problem solving.



Principles of Reaction:

          The instructor notes the extent to which individuals seem to be tied to regularized patterns of thinking and he or she tries to induce psychological states to generate creative response. The more the problem is difficult to solve it is necessary for the teacher to accept far fetched analogies so that they develop fresh perspectives on problems.

Support system:
            The group needs most of all facilitation by a leader competent. In case of scientific problems a laboratory in which it can build models and other devices to make problems concerns and to permit practical invention to take place.

Application:
       Step I : The teacher asks the students to describe a given topic. This can be done orally or the students can write down the topic. Descriptive words are then listed on the board.
 Example: The topic is ‘Feelings’
Descriptive words: love, hate, anger, sadness, guilt, happy, remorse, joy, satisfaction etc.
Step II Students examine the descriptive words and form analogies between the words and an unrelated category such as plants, animals or machines. After all students have given an analogy, the best one is voted on by the class.
Example: Think of a plant that reminds you of the listed words.
Analogies:         ‘A rose reminds me of Love’
                        ‘ Jasmine reminds me of Valentines’ Day  and happiness’
                        ‘Lily reminds me of death and sadness.’
Step III: The teacher asks students to think about how he/she would feel to be the object chosen in Step II. Students must also tell why they have that particular feeling.
Students responses are recorded.
Example: How would it feel to be a ‘Rose’?
Responses: alive, happy, safe, smelled, plucked, ignored, curdled, held on, dead, recognized, good, loved, bad, crushed.
Step IV: The students are asked to review their responses to find pairs of words which seem to ‘fight’ or are in opposition to one another.
The class votes for the pair of words that represent the best compressed-conflict.
Example: ignored- loved , good- bad, happy- sad, alive-dead,   held on- crushed
Step V: The teacher asks for another category for a direct analogy and the class must think of example of that category which are best described by the compressed category chosen in Step IV.
Example: “Animal” is the analogy, “alive- dead’ are the characteristics.
Direct Analogies: lion, dog, cat, bear, dinosaur etc.
Step VI: The class talks about the original topic by comparing the last direct analogy to the original topic New images are created.
Example “Feelings are like lions. They are alive but, sometimes appear to be dead.” “Feelings are like Roses and Lilies. Sometimes they make you happy and some times they make you sad”.
Step VII: Students evaluate the writing done before and after the model to see if more creative insight has been added. The must also analyse the thought process involved.

Merits:
1.       develops creativity
2.       develops problem solving ability
3.       ensures co-operation
4.       concern for fellow being

Demerits:
1.       expensive in case of scientific problem as it requires laboratory.
2.       Competent teacher to guide
3.       conducive environment


       ADVANCE ORGANIZER MODEL OF TEACHING
          
          An advance organizer is a cognitive strategy proposed by Ausubel in his Subsumption Theory, which allows the learner to recall and transfer prior knowledge to the new information being presented. This theory is based on the idea that learning is facilitated, if the learner can find meaning in the new information. If a connection can be made between the new information and previous knowledge, the learning experience will become more meaningful to the learner. Therefore, the new information will be learned.
The advance organizer is not a strategy used by the learner, but rather an instructional strategy used by the teacher. In essence, the advance organizer is a brief, general speech prepared by the teacher, before presenting the new material, to introduce the new lesson. In designing the advance organizer recall of previous knowledge relevant to the new knowledge is important. It should provide a bridge that links the known to the unknown, by including an abstract outline of the new information and a restatement of old knowledge. Theoretically, this will encourage transfer and application of old knowledge, to make the new knowledge more meaningful to the learner. In SLA advance organizers could be used to help the learner categorize new learning, in relation to their native language. The learner could then distinguish similarities and differences in the target language and their native language, thus carrying out a cognitive comparison between deviant and correct target language, forms or utterances. This may even reduce learners' errors as conscious attention is focused on these differences and similarities. The use of advance organizers does fit in with current teaching approaches, particularly with the communicative language approach. For in this approach, learners negotiate for meaning and the teacher acts as a facilitator of the communication process.

Types of advance organizer:
          Ausuble labelled two types of advance organizers depending on the learner’s degree of familiarity with the material which is as follows:
1. Expository Advance Organizers:
They provide general model of class relationship as a general subsumer for a new class, sub-class, and species before more limited subsumer are provided for the particular sub-class or species. These are used when the material to be learnt is complete.
2. Comparative Advance Organizer:
They are used most with relatively familiar materials. They are designed to integrate new concepts with basically similar concepts existing the cognitive structure, yet they are also designed to discriminate between the old and new concepts in order to prevent confusion caused by their similarity.
Syntax:
It consists of three phases:
Phase 1: Presentation of Advance Organizer:
          During this phase, first of al the objectives are explained and clarified and after which the advance organizer is presented.
Phase 2: Presentation of Learning Task or Material
          At this stage, the learning material is presented. This is presented through lectures, films, scripts, discussion, experiences; extra reading material etc. the learning is organized in logical order. Attempts are made to maintain motivation and interest.
Phase 3: strengthening Cognitive Organization
          At this stage, the cognitive material is strengthened. The purpose of this stage it to anchor new material with old. This ism integrative reconciliation is brought about. This is brought about by asking the students to prepare the summary of major attributes of new material, repeat definitions, and ask students to differentiate the closely related subject.

Social System:
          In this model, the teacher retains control of the intellectual structure, as it is necessary continually to relate the learning material to the organizers and to help students differentiate new material from previously learnt material. In phase, three, however, the learning situation is ideally much more interactive, with students initiating many questions and comments.

Principles of Reaction:
          The teacher’s solicited or unsolicited responses to the learner’s reactions are to be guided for the purpose of clarifying the meaning of the new learning material, differentiating it from and reconciling it with existing knowledge, making it personally relevant to the student, and helping to promote a critical approach to knowledge.
Support System:
          Well organized material is the critical support requirement of this model. The effectiveness  of the advance organizer depends on an integral and appropriate relationship between the conceptual organizer and the content.
Application:
1. It is specially useful to structure extended curriculum sequences or course and to instruct students systematically the key ideas of a field.
2. It increases the learner’s grasp of factual information linked to and explained by the key ideas.
3. The model can also be shaped to teach the skills of effective reception learning.
4. Whenever ideas or information needs to be presented, renewed, or clarified, the advance organizer is useful model.

How to Use:
       Ask students to compare and contrast the new content based on what they know. For example, what can they tell about its color, shape, smell, feel, or taste? Demonstrate by using a related determinant. For example, use baseball to teach cricket, or ping pong to teach tennis.
       Give a scenario and ask students to infer rules based on their current knowledge.
       Have students identify the characteristics of a known quantity and then relate it to the new idea/concept. For example, offer renderings of different types of geometric forms before discussing their individual likenesses and differences.
       Identify a problem and ask for a reason why it may occur (before teaching the reason). For example, you might discuss the origins of a war before describing its major battles.
Merits:
1.       meaningful assimilation of information and ideas.
2.       it nurtures an interest in a inquiry and precise habits of thinking.
3.       has wide applicability to different curriculum areas.
Demerits:
1.      time consuming
2.      competent teacher
3.      all concepts cannot be taught in this manner
               






                           INDUCTIVE THINGING

It is a skill that is developed by three teaching strategies
First is Concept Formation (the basic teaching strategy)
Second is Interpretation of data and
Third is Application of Principles
           This is developed by Hilda Taba.

CONCEPT FORMATION
      It involves (1) identifying and enumerate the data relevant to a topic or a problem, (2) grouping these items into categories whose members have common attributes, and (3) developing labels for the categories.

INTERPRETATION OF DATA
     It is built around the mental operations such as interpreting, inferring, and generalizing.

APPLICATION OF PRINCIPLES
         The third stage is of applying principle to explain new phenomena                 ( predicting consequences from conditions that have been establish, such as predicting which countries have similar interest that might affect how they would vote on relevant issues in the United Nations Assembly).
SYNTEX
It has three strategies and every strategies has some phases
 Strategy one: Concept formation
Phase one: Enumeration and listing
Phase two: Grouping
Phase three: Labeling, Categorization
Strategy two: interpretation of data
Phase Four: Identifying Critical relationship
Phase Five: Exploring Relationship
Phase six: Making Inferences
Strategy three: Application of principles
Phase seven: Predicting Consequences, Explaining Unfamiliar Phenomena, and Hypothesizing
Phase eight: Explaining and/or Supporting the Prediction and Hypothesis
Phase Nine: Verifying the Prediction
SOCIAL SYSTEM
For all the three strategies, the atmosphere of classroom is cooperative, with a good deal of pupil activity The model has high to moderate structure.It is cooperative, but the teacher is the initiator and controller of activities.  

PRINCIPLE OF REACTION
The teachers’ primary mental task in the course of the strategies is to moniter how the students are processing information and then to use appropriate eliciting questions. The important task for teacher is to sense the students’ readiness for new experiences and new cognitive activity with which to assimilate and use those experiences.

SUPPORT SYSTEM
         Students need raw data to organize and analyze. The teachers’ job is to help them to process the data in increasingly complex ways and , at the same time, to increase the general capacities  of their systems for processing data

Conclusion
              Whatever be the model of teaching the main objective is to reach the objective of teaching. The more structured/planned the teaching is, the result is more effective. All these models are supporters for a teacher to present well in the class. Doing so his/her efficiency increases in teaching. It helps in gaining confidence.
