Skill of illustration

Skill of illustration with example in physical science

An Illustration is the decoration of some words that defines or explains a concept, explanation or visual indication of a text, concept or process, designed for making a concept easier in a proper media, such as posters, charts, magazines, books, teaching materials (TLM), film pictures, video  tapes, games and films. An illustration is typically created by teacher. Illustrations are also known as an example; either in writing or in picture form.

Meaning

Some of the questions like what is the role of Illustrations or examples in the teaching learning process? What if a teacher explains with the help of examples? What is illustrating? Are the frequently asked questions which are arises almost in everyone’s mind. A teacher teaches with examples and make a topic very easy for students, if the teacher have a bit of less mastery in giving example he is not able to explain the complex topics. By the use of different diagrams, clarifications and with the help of some examples then we call it illustrating. This is skill in which a teacher must be trained, if he is not then the teaching may not achieve the goal which setup before. The examples which are being given during the teaching learning process are very relevant to the topic so that they useful in teaching. If the examples are not relevant to the topic they may misguide the students. So it is very important that teacher should have the skill of illustrating. The skill of illustrations has its own purpose in teaching learning process that’s why they are important too.

Following are the few objectives of illustrating-

  • To make a lesson interesting.
  • To relate known knowledge to unknown knowledge
  • To make complex things easy and interesting
  • To make the use of multiple senses or fronts of students



How to use an example? What kind of example is suitable for the teaching? There is the way of selecting the proper example or we can say the approaches of using illustrations, which usually helps a teacher to know that the type of examples and its usability. There are two main approaches or ways which helps a teacher to select the suitable example during teaching-learning-process. These two approaches are as following-

Non-verbal approach


Verbal approach


There are some components of illustration skill which affects so much the learning of students. Usually these components must be included while illustrating something in the class. These components make examples so meaningful if it is done in a proper way. The teacher must have the knowledge of these components so far which are as following-

Components

  1. The selection of simple, understandable and relative examples
  2. Selecting interesting examples
  3. The selection of proper medium for illustration
  4. Selection of right method for illustration
  5. Proper number of examples (say 4 to 5 in one topic)
  6. The relevancy of examples with concepts and ideas
  7. The examples given by the students are important (teacher try to make students to give relative examples)
  8. Understanding to concepts (through the use of examples the concept becomes easier to understand so it must be understood by students)

These are the components through which we can measure the teacher’s strength in illustrating skill. The understanding of these components makes this skill very effective for teaching learning process. During teaching all these components are used and measured one by one and the teacher also make sure that there must be at least one example from one component while teaching. Using them systematically brings effectiveness in teaching and the difficult and complex topics can be understood easily by the students.

There are some important facts about good illustration or we can say the precautions while using the illustrating skill, these points are as following-

  • All the examples should be related to the specific objectives
  • These examples should be related to the concept being taught
  • They must be interesting
  • All these examples should be as per the standard of the students
  • They must be of different kinds (should not be given only one type of example).

Type of test items

TYPE OF TEST ITEMS: An item is the basic unit of interaction on a test. What we often call a test  question  is more properly known as an  item ,  since it may not be worded as an actual question. The student's feedback is also more properly known as a  response  rather than an  answer , but we won't get too particular on that point. Items can be written in various formats, including multiple choice, matching, true/false, short answer, and essay. We will discuss some of these formats in another article. Since items are the actual points of interaction of students with the test, item quality is probably the most recognizable indicator of the overall quality of the test. High quality  test items  take time and effort to write, but are essential to a valid test. Items must test skills and knowledge of the subject at hand, not the student's test taking  skills.
