SIMULATION


SIMULATION
Simulation methods are ways to imitate of the operation of real-world systems. It first requires that a model be developed representing characteristics, behaviors and functions of the selected system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time.
Simulation refers to the imitation of real-world activities and processes in a safe environment. Simulations aim to provide an experience as close to the ‘real thing’ as possible; however, a simulated activity has the advantage of allowing learners to ‘reset’ the scenario and try alternative strategies and approaches. This allows learners to develop experience of specific situations by applying their wider learning and knowledge.
Simulation is a very general and flexible teaching approach that can be used in most disciplines, but this means that how it is implemented will vary greatly. The key to simulation is that it is a dynamic rather than fixed experience, with the scenario changing realistically according to the actions of the participants and the participants adapting as a result of changes to the scenario – in a sense, a simulation is a mechanism for learners to obtain real-time feedback on their actions.

STUDENT SEMINAR


STUDENT SEMINAR
This is the best technique for some situations. This is mostly used alone. When the topics are easy the teacher can ask the students to prepare an essay on the topic and present it to the class. The topics may be assigned for all the students. The papers may be read in the class one after the
other. After the presentation the students can ask questions and raise doubts. The paper reader will answer these questions. The teacher will be the chairman or leader. The size of the class will be small containing a maximum of 20 to 25 students. The class teacher acts as a resource person too. In a typical seminar the strength may range from 6 to 25 and it usually has an appointed chairman and one or more resource persons. It is a common of discussion group and is ideally suited for the study and analysis of difficult problems over a period of time. The group increases in its effectiveness when members become acquainted with each other, and not to feel threatened by each other and are willing to express ideas frankly.
A seminar is a form of academic instruction, either at an academic institution or offered by a commercial or professional organization. It has the function of bringing together small groups for
recurring meetings, focusing each time on some particular subject, in which everyone present is
requested to actively participate. This is often accomplished through an ongoing Socratic dialogue with a seminar leader or instructor, or through a more formal presentation of research. It is essentially a place where assigned readings are discussed, questions can be raised and debates can be conducted. Student seminars are the open presentations done by the students before their peers and teachers. The word seminar is derived from the Latin word seminarium, meaning “seed plot”
Some Tips for Seminar Preparation
Choose a Good topic: Choose a topic which will sustain your interest and will allow you to exhibit enthusiasm during your presentation
Keep your Audience in Mind: The primary objective in giving a talk should be a communicate an interesting idea to students who attend the seminar. This means that the talk should be delivered in a way that students in attendance understand what you are saying, so be mindful of their background.
Tell a story/ anecdote: Begin with solid motivation for your problem and plenty of illuminating examples. Only after your audience understands what your topic is and why they should care about it should you spend time working carefully through the relevant science.
Keep timing in mind: Choose a topic that you can motivate and explicate comfortably in this window of time.
Scoring Indicators for Evaluation of Seminar
1. Ability to Collect Data: Sufficient, Relevant, Accuracy of facts
2. Ability to Prepare Seminar Paper: Introduction, Content Organization, Conclusion
3. Presentation: Communication, Competence, Fluency, Spontaneity
4. Understanding the Subject: Involvement in the Discussion, Responding suitably, Capacity to handle differences of opinion
Advantages
1. Students develop the habit of reading more books.
2. They develop the ability to collect relevant information from different sources.
3. They are able to remove shyness and contribute something in the class.
4. They develop a high degree of participation.
5. They are able to face the students and answer the questions boldly.
Disadvantages
1. It requires more time, more space and more personnel.
2. Sometimes only a few students will participate in seminar.
3. Unless the chairman is skilful, the seminar easily degenerates into a question and answer session or a lecture.


ROLE PLAY


ROLE PLAY
Role playing can be defined as an attempt to make a situation clear or to solve a problem by uncharged dramatization. Role playing method is based on the imitation of a role. This method is very helpful in bringing out changes in the personalities of students including developing their social skills. It can be used for various purposes. It can also be used to teach some simple topics to younger children, e.g., solar system, balanced diet. Here the learners acts out a problem in a completely spontaneous manner & through this explore the problems by enacting problem situations. Role playing is dealing with problem through actions. It is teaching techniques & is based on the idea that acting out a role will help or enable a student to get an indepth view of a problem that cannot be understood merely by reading a book or listening a lecture. A role is patterned sequence of feelings , words & actions.
Purposes of role playing
·         To motivate or launch units
·         To culminate units
·         To make clear historical or contemporary situations in which there are conflicting emotions, different points of view, biases, problems caused by differences in race, age, religion, nationality or ethnic background, & so on.
·         To change attitudes
·         To teach values
·         To  teach content having to do with human relationships
·         To develop citizenship skills by showing both the successful & unsuccessful methods we use to solve inter group & interpersonal problems, by providing practice in taking real life roles, & by practicing the democratic process.
Conducting role playing
1.    Preparation
o   Preparing for role playing – select significant issues & brief the problem to be faced.
o   Selecting the players – as far as possible select players who can identify with the roles. Select several casts & limit each cast to two to five players.
o   Preparing the audience – be sure that the no audience knows the situation & brief them how to behave.
o   Preparing the players – allow pupils plenty of time to prepare. Be sure each players knows what he is going to do. Set the stage.
2.    Playing of the roles
o   Keep the role playing short.
o    Let the pupils play it out.
o   Do not evaluate the acting language.
o   Do not allow audience to interrupt.
3.    Following up the enactment
o   Discussion – discussion should analyse the interpretations, solutions, reactions & so on. Try to evaluate what has been learned in the discussion you may have to do some probing.
o   Re-enactment – it is wise to follow up a role playing with a second or third role playing of the problem or situation.
Advantages
·         Develop deep understanding regarding various process or phenomena in science.
·         Developing problem solving skills & attitudes.
·         Explore subject matter in varied ways.
·         Develop interpersonal communication skill.
Limitations
·         Pupils who are not well prepared for role playing may not take it seriously.
·         Role playing will not work unless the atmosphere in the class room is supportive.
·         Pupils find it difficult to enter the roles properly; especially they are not well briefed on the assignments.
·         Role playing is time consuming.  



QUESTIONING TECHNIQUE


QUESTIONING TECHNIQUE
The questioning is a technique as well as method of teaching. It is given by Socrates. It serves various purpose in the teaching learning situation. Questioning is also an important teaching skill. An effective teacher employs questioning technique appropriately & also prepares good questions. Characteristics of questioning are as follows:
a)    Exploring the entering behavior of the learners.
b)    Provides motivation & encouragement.
c)    Makes them active in the class room.
d)    Establishes a chain of learning by linking previous knowledge with new knowledge.
e)    Provides the direction to the mental process of learning.
f)     Develops thinking & analytical abilities of the learners.
g)    Revise the teaching content.
h)   Evaluate the effectiveness of teaching learning.
Types of questions             
1.    Introductory questions – these are used in introducing new topic or lesson to the students. The introductory questions are based on the previous knowledge which is related new knowledge. These questions employ from known to unknown maxim of teaching.
2.    Developing questions – after introducing new topic, some questions are asked to develop the new content. It employs from logical to psychological technique of teaching.
3.    Recapitulatory questions – in the learning process law of practice or law of exercise plays a significant role in teaching new content. These type questions provide the situations to practice the learned content. The question serves three purposes:
o   To consolidate the learners new knowledge.
o   To organize the ideas of facts at proper place.
o   To provide well organized situation of the content.
4.    Evaluation questions – at the end of lesson the teacher puts questions to test the knowledge of the learners to assimilate whatever they could learn the content. Generally oral questions are asked. These are short answer type. Sometimes these questions are helpful to diagnose the weakness of learning. Remedial instruction can be provided to learner by the teacher. It also function a feed back to the teaching learning process.
Another way to classify questions
Close and Open Questions
Close questions accept only a narrow range of responses and the number of responses is limited. Close questions expect convergent thinking. Some close questions allow only one “correct” or “right” answer. Answers to some close questions are “yes” or “no”.
Open questions emphasize divergent thinking and can accept a wide range of responses. The number of answers to an open question may be two or more. Open questions encourage pupils to use their past experience and justify their opinions/thinking. It is important for teachers to choose whether to use close or open questions depending on the teaching contexts.
Low and High Order Questions
Questions can be classified depending on whether they are low order or high order. Examples of low order questions are perceiving questions (based on observation) and recall questions (based on knowledge or memorisation of facts).
High order questions encourage pupils to think rather than just to remember some facts that they have previously acquired. Those questions often require higher cognitive level. It is important to note that it does not mean high order questions are always better than low order questions. After putting pupils’ understanding and contents of the lesson into consideration, a well-balanced mixture of these questions is needed.
Characteristic of good questions
An effective teacher should be able to construct & use good questions. Preparation of good question requires insight, experience, mental ability & awareness of teaching problems. Teaching is a very social & dynamic activity. A teacher should have the full understanding of good questions.
·         The language of questions should be simple & easily understandable.
·         The form of the questions should be straight forward. There should not be any ambiguity.
·         The questions should have the definite meaning.
·         The questions should be in logical sequence. It should be psychologically workable.
·         The questions should be thought provoking.
·         The questions should serve the purpose of teaching learning.
·         The questions should have utility from learners & content point of view.

PROJECT METHOD


PROJECT METHOD
This method was propounded by W.H Kilpatrick. This method was perfected by J.A Stevenson. The base of this method lies in the philosophy of pragmatism. John Dewey wanted that education should be for life and through life. This method emphasizes on building a comprehensive unit around an activity which may be carried out in school or outside. The essence of this method lies in the fact that a group of students do a purposeful task. This implies the students undertake the activity in a group or individually over a period of time. It may include a number of activities and the end product is in the form of written report or a display.
“A project is a whole-hearted purposeful activity proceeding in a social environment”- Dr. William Kilpatrick.
“A project is a problematic act carried to completion in its natural setting”. – Stevenson.
“A project is a bit of real life that has been imported into school. – Ballard.
Thus, project is a purposeful activity and planned activity which is achieved in social, natural situations created in schools.
PRINCIPLES OF PROJECT METHOD:-
1. The Principle of freedom.
2. The Principle of purpose.
3. The Principle of activity.
4. The Principle of interest.
5. The Principle of utility.
6. The Principle of correlation.
7. The Principle of sociability.
8. The Principle of experience.
9. The Principle of reality.
10. The Principle of learning by doing.
TYPES OF PROJECT:-
All the project can be divided majorly into two types.
(i) Individual Project.
(ii) Group Project.
According to W.H. Kilpatrick projects are of four project.
i) Producer projects
ii) Consumer projects
iii) Problem projects
iv) Drill projects.
PRODUCER PROJECT: -
Here the emphasis is on actual construction of a material object or article.
CONSUMER PROJECT: -
Here the emphasis is gain on obtaining either direct or vicarious experience, such as reading and learning stories, listening to a musical delectation etc.
PROBLEM PROJECTS:-
The main purpose is to solve a problem using intellectual process, such as determining the density of a certain liquid.
DRILL PROJECTS: -
This type of project emphasizes on attaining a certain degree of skill in a reaction as learning a vocabulary.
Steps of Project Method:-
1. PROVIDING A SITUATION: -
The teacher provides a situation to the students which must create same problems and students must feel interested to work.
2. CHOOSING AND PURPOSING: -
The students are tempted to choose a project. The teacher should stimulate discussion by suggestion. While choosing the project the teacher should bear in need that it should be of real need to students. The purpose of project must be clearly defined to the students. The project must be common and acceptable to all. In case of wrong choosing, teacher must help students tactfully to see that the students choose a better project. They should be asked to write down the reasons for selection.
3. PLANNING: -
The success of the project lies in the good planning. The students should plan out ht whole project under the guidance of teacher. Every child must be encouraged to participate in the discussion and make suggestion. All the students are encouraged to write down the plan neatly and properly.
4. EXECUTING: -
Execution of different activities to different students on the basis of their capacity leads to successful completion of the project work. It is the longest step and requires meticulous assignment of duties to different students or groups the teacher must guide and encourage students. It is the duty of the teacher to keep watch on the process of activities and instruct as and when requirement.
5. EVALUATION: -
This is very important step as; the students review the project and find out mistakes if any. Self-Criticism is very important at this stage. The students discuss their work and rectify their mistakes and recollect useful knowledge. The teacher sees that the objectives of the project have been achieved.
6. RECORDING: -
The students keep a complete record of entire activity. How they planned, discussions were held, how duties are assigned, how criticism were made, which will help them in their future work.
ROLE OF TEACHER: -
1) Teacher must be a friend, guide and working partner.
2) Teacher must have through knowledge of individual student and allot work accordingly.
3) Provide democratic atmosphere.
4) He should learn with students and should not claim to know everything.
5) He must be inexperienced, initiative and process tact for creating positive ambience.
MERITS OF PROJECT METHOD: -
1). This method is based upon the laws of learning. They are as follows:
a. Law of readiness
The students are made ready to learn by creating interest, purpose and life situations.
b. Law of exercise
The student’s carry out activities in the real life situations, the experiences gained thus are very useful in the later life of the students.
c. Law of effect
The sense of success and satisfaction should follow the learning process. This law makes it essential for the teacher to make the student satisfy and feel happy in what he is learning.
2) It promotes Co-operative activity.
3) It arouses and maintains interest of students.
4) It keeps the students on freedom of thought and action while doing the work.
5) It develops scientific attitude.
6) It widens the mental horizon of student.
7) It develops dignity of labour.
8) The students learn by self activity.
9) The correlation of subjects is best followed in this method. The subjects are not treated as water tight compartments.
10) This is a psychological method.
DEMERITS OF PROJECT METHOD: -
1. The knowledge is not acquired in a sequential manner.
2. There may be a chance of overlapping of subject matter.
3. If not planned and executed properly them, it may not be completed in time.
4. It is a time consuming process.
5. It may be a costly affair where in same items/things may not be available at times.
6. There may be overdevelopment of individualism and under development of co-operation and group responsibility.
7. If the topic in wrongly selected them the objective may not be achieved.
8. It gives to students a superficial knowledge of great many things. Therefore it is not suitable for all types of students.
9. This method is not suitable for a mature teacher.
10. The whole syllabus, for higher classes cannot be accomplished with this method.
SUGGESTIONS TO IMPROVE: -
1. The topic should have same educational value.
2. Project should be selected according to the student’s interest.
3. Entire course should not be planned only using this method.
4. The objectives of the project must be clear and defined.
5. Students should be assigned various duties according to their capabilities.
6. The students should be given freedom to interact among themselves.


PROBLEM-SOLVING METHOD


PROBLEM-SOLVING METHOD
It is a method in which a specific problem is given to the students and they are required to find out the solution through objective reasoning and thinking. This method is also highly suitable for teaching of science. In this method, the teacher is going to act as a guide and will be in the background and the students should take active participation in finding out the solution to the problem in hand.
The students should know what he is doing and why he is doing. The problem should be of educational importance and should have educational value and must be selected from the real life situation. Also the problem chosen should be worthwhile and should have practical value. The problem should be chosen in such a way that it can be fitted well in the present curriculum organization in the school to avoid various administrative difficulties.
Steps in problem-solving method
The following steps are involved in the problem solving method.
A. Recognizing the problem
B. Defining and interpreting the problem
C. Collecting data related to the problem
D. Organizing and evaluating the data of problem
E. Arriving at final conclusion
F. Verifying the result
A. Recognizing the problem
In this step, the teacher should organize a discussion of a problem or problems with the students and based on the discussion, the teacher should create a problem in such a way that the students should feel that it is their own problem and they should solve it. The teacher should organize the problem in such a manner that it should arouse student’s interest to study and solve it.
B. Defining and interpreting the problem
The teacher should explain the problem given to the students in detail or may be interpreted by the students themselves through discussion. All the attributes constituting the problem must be made clear to the students and the problem must be defined in a systematic manner.
C. Collection of data related to the problem
In this method, the teacher should suggest the available resources like books, journals, periodicals, etc. with respect to the problem given to the students. Also he must encourage the students to collect data from different sources.
D. Organizing and evaluating the data of problem
The data collected must be well organized by the students and all the unwanted superfluous matter should be deleted. In this stage, the teacher can help the students in arranging and classifying the materials collected in a scientific way.
E. Arriving at final conclusion
After analyzing all the important points with respect to the problem, a tentative solution may be discussed among the students and finally they will arrive at a conclusion collectively.
F. Verification of the result
Finally the solution to the problem must be verified by applying this result in a new situation to detect the discrepancies if any, in the facts already discovered.
Merits
The students will get training in the art of solving a problem in actual life situations
Reflective thinking and the power of reasoning can be developed with this method
Self-confidence among the students can be developed through this method.
It helps the students in developing the power of critical judgement as they have to think a lot to arrive at correct solution to the problem through practice
It inculcates the habit of open-mindedness and tolerance.
Demerits
It is difficult for the teachers to organize the content of science according to the need of the students and therefore, he cannot always give real life problems.
It is a time-consuming process
Textbooks and other written materials are not available as per the guidelines of the problem-solving method.
This method is useful only for the students studying higher classes and for those who have higher level of thinking.
All the lesson or topics cannot be taught by his method.


PANEL DISCUSSION


PANEL DISCUSSION
Definition: It is a discussion in which few persons ( the panel) carry on conversation in front of the audience.  At the end of the discussion audience also participates. The audience put important questions and the experts answers them and clarify the points.
Purpose - Purpose of the panel discussion is to reproduce the features of a small discussion group for the benefit of a larger group.
OBJECTIVES
·         To provide information and new facts.
·         To analyze a problem from different angles
·         To identify the values.
·         To organize for mental recreation
TYPES OF PANEL DISCUSSIONS
1. Public panel discussions
2. Educational panel discussions
PUBLIC PANEL DISCUSSIONS - These are organized for common men problems.
Objectives:
·         To provide factual information regarding current problems
·         To determine social values
·         To recreate the common men
E.g. annual budget, educated unemployment , increase in price of things.
EDUCATIONAL PANEL DISCUSSIONS - Used in educational institutions to provide factual & conceptual knowledge and clarification of certain theories and principles.  Some times these are organized to find out the solutions of certain problems
Objectives -
·         To provide factual information and conceptual knowledge
·         To give awareness of theories and principles
·         To provide solution of certain problems
Procedure of panel discussion
Types of members in panel discussion - Instructor, Moderator, Panelists, Audience
INSTRUCTOR - Plays most important role in panel discussion. Plans how , where , when panel discussion will be organized. Prepares the schedule for panel discussion . Sometimes rehearsal is also planned.
MODERATOR - Keeps the discussion on the theme and encourages interaction among members. Summarizes & highlights the points. Should have mastery on the theme or problem of the discussion.
PANELISTS  - There are 4 – 10 panelists in the discussion . Members sits in a semi circle shape in front of the audience. The moderator sits in the middle of the panelists.  All panelists must have mastery of the subject matter.
AUDIENCE  - Audience are allowed to put question and seek clarification. They can present their point of view and their experiences regarding the theme. The panelists answers. In some situations moderator also tries to answer the Qn.
At the end of discussion , moderator summarizes the discussions and presents his point of view. He expresses thanks to panelists and audience.
Characteristics of panel discussion -
Used in university & college level to organize teaching at reflective level. Develops the ability of problem solving. Helps to understand nature, problem or theme of discussion. Develops ability of presentation of theme and giving their point of view logically. Develops right type of attitude and ability to tolerate anti- ideas of others. Helps in creative thinking. Develops manners of putting Qn.s & answering them.
Advantages of panel discussion
·         Encourages social learning
·         Higher cognitive and affective objectives are achieved
·         Used to develop ability of problem solving and logical thinking
·         Develops capacity to respect others ideas and feelings & ability to tolerate.
·         It provides opportunities of assimilation of theme and content.
Limitations of panel discussion
·         There are chances to deviate from the theme of discussion
·         some members may dominate
·         There is possibility to split the group in to two subgroups ( for & against)
·         If panelist belong to different groups, it may not create appropriate learning situation
How to organize effective panel discussions - There should be a rehearsal before actual panel discussions . The moderator should be a matured person and should have the full understanding of theme / problem & should have full control over the situation. The seating arrangement should be such that every one should be of equal distance & should observe each other. Moderator should encourage constructive discussion among panelists and audience.
