  Pressure:. Imagine that you are standing on the surface of road ,your feet exerts force on the earth. The area under your shoe bears the force of your body. The ratio of the applied force to the area is called pressure. When you talk about a high heel, the high hell exerts more pressure on earth than the shoe, because the area is small but the force is same. For example a man is Sitting on a ground; the weight is the force which is acting on the surface of earth. The force ( weight of man) acted upon the area he covers while sitting cause the pressure of the man on the earth.But a man is standing applies the same force ( weight) with different area in contact with the surface and therefore exert a different pressure.          Different Area in contact will give different value of the pressure .                                            Perssure i...

  Force:. When we think of a force, we usually imagine push or pull exerted on some object. For instance,you exert a force on a ball when you throw it or kick it. What happen to an object when it is acted by a force ? Force is commonly defined as a push or a pull. We can apply the forces through contractions or extensions of our muscles .when you open a door, you pull it. By the contractions of your muscles we can exert a force . A push force moves something away from you and the pull force moves something closer. You can push hard or gently ,left or right so the force has the magnitude as well as direction. Force is a vector quantity . The symbol F is used to represent the vactor force . If you pull a spring or kick a ball ,they change their position due to the application of force. When you throw a ball in air it comes back due to the force of gravity of the earth. Force can be categorized into two types one is contact force and the other is the non- contact force. In fact when t...

Taxonomies of Objectives:.    The Science of classification in general and any specific classification respecting it's rules i. e.taxonomy of educational objectives,.     A taxonomy is a kind of hierarchical organization of knowledge. If one understands all the concepts of taxonomy, this understanding covers all aspects of that knowledge. The relationship among the items of a taxonomy are hierarchical as there are superordinate ,subordinate and coordinate concepts in taxonomies. There are other hierarchies which are not based on inclusive relationship.                                             Blooms, Taxonomy:.    Bloom and his fellow researchers published a Taxonomy ,educational objectives  ( cognitive domain) which influenced the practice of education to a large extent. Bloom and his colleagues categorized objectives from simple ...

  Aims ,Goals And Objectives: teaching is a practical activity and like any practical açtivity it must have some aim or set of aims. Aim provides purpose to teaching ,this is the kind of definition which allows us to talk about success or failure ,quality ,improvement etc. If sailing has no aim, then one might successfully sink. In the same way a clear conception of aims of education are necessary both for understanding of the enterprise and for assessing or designing any research on it. If we do not know the aim of education ,how can we assess whether any person has been successfully education, whether the way we are educating the children is effective and whether this is appropriate research or not .Quin (1989 p. 38) defines as :. Aims: To intend ,to determine a course ,purpose, intention, plan.    Goal:. The end towards which effort is directed. A condition or state to be brought about through a course of action.      Objective:.    Something t...

  Cognitive  Teaching Strategies And The Teacher:.      By these teachers can prepare students to learn new material by reminding them of what they already know. Teachers can use questions, can help students to develop linkage and recall new information. Detail of this as:.                                                      (a).      Making  Learning  Relevant / Activating  prior knowledge:.                            Effective teaching includes making Learning Relevant ,prior knowledge elaborating, organizing of information and using question techniques. The eight  instruction events as designed by Slavin (1994,p.266) are:  1. Activating motivation;.                    ...

  Instructional Strategies And psychology: classroom is a world uncertainty prevails as a teacher is never sure which student will show up. School day may be full of interruptions and unforeseen events. To deal with these, teacher takes decisions and in this regard psychology helps the teacher especially in choosing the instructional strategy. These instructional functions are as:  1) Daily review and checking homework 2) presentation 3) Guided practice 4) Correctives and feedback  5) Independent practice (seat work)   6) wheekly and monthly review.          Educational psychology is social science which tries to explain teaching learning process.   It tries to solve the problems involved in scientific basis. Teaching strategies are used to accomplish goals ,i .e. desirable ends. Educational goals primarily deal with learning, memory and transfer of cognitive,social and moral behaviours .Due to increasing effectiveness, it is recomm...

Unitary Method:  This is the method of carrying out a calculation to find the value of a number of items by first finding the cost of one of them. It is a technique in Mathematics to solve particular types of problems. Unit means one,in this method, we first find the value of one. To find the value of one ,. When we have the value of many ,we divid:    Steps: (i)Find the value of one unit.   (ii) Find the value of required units .                                     Example  No 1: 5 pencils cost Rs 15 .how much does 1 pencil cost?                                      Solution:.         Cost of 5 pencils= Rs 15                                       ...
