While teaching social sciences, a teacher uses various objects, materials, people, situations and experiences, etc. to make teaching-learning activities meaningful. All these constitute learning resources to help students learn in a meaningful way and attain the objectives of teaching-learning. Let us discuss some of these learning resources which are relevant to the teaching of social sciences. Important Points Time-Lines: Timelines are used to help students keep track of key events in history. Students get real pictures of when events occurred and enable them to arrange the events in the proper sequence. If the students prepare the timeline of a history unit before the discussion of the unit, they understand the unit and they can also clearly understand the cause and effect of the events. They can prepare timelines in their classroom by using a bulletin board. Timelines are a very effective medium used in teaching history and other segments of social studies. The major utilities of time-lines are the following: Development of a sense of time. Finding out the relationship between two periods of time. Focusing the attention of an entire class on a visual device. Used for review purposes and reinforcing learning. Key Points Timelines can be used for the following instructional purposes: making the sequence of events in history. stressing the most important events in history. telling the story of events in a logical sequence. Hint Kenworthy (1962) suggests the following guidelines for the use of timelines in social studies classes: Have a large time-line pasted for weeks or months in front of the class, preferably above the chalkboard, for constant reference. Have pupils prepare simple time-lines as part of their homework. Purchase printed time-lines. Use the timeline as a teaching device. Use pictures or symbols on time-lines. Make sure that time divisions are equal Hence, we can conclude that all of the above statements are correct regarding the utility/utilities of time - lines as a learning resource in social science.
