1 Guidelines for lesson creation [with basic topics to be covered] (1-1, 1-2) Parts of a computer and identifying What minimal topics must to be covered in each lesson? List only the 4 main parts of a computer and their main functions Monitor CPU Keyboard Mouse Emphasis on : Just the names and minimal functionality The analogy with parts of the body What other optional topics may also be covered Can also mention Speaker, mike and printer and say that they will be covered in detail later Suggestions for detailing All different parts are connected and talk to each other Explain the fact that it is useful device with basic examples: play games, do homework Fun tool and a useful tool to know about Basic function of each part Keyboard gives input You can see what you enter through the keyboard on the Monitor Mouse helps us to move around the Monitor Suggestions for worksheets Pictorial representation of parts and identification Learning the correct spellings of the parts Pictures of activities: typing, reading on the monitor, switching on and relate them to the appropriate part of the computer Giving a list of objects and picking the odd object out Drawing the part wrongly and asking them to correct Draw the connections between all the parts after taking them to a lab [ CPU to mouse/keypad/ monitor, power cord from CPU / monitor ] Learning the names of parts by typing on the keyboard Identifying the name when picture of each part is shown Drawing the parts through dotted paths given the names Given the picture of a monitor, keyboard, CPU draw lines between them Colour different parts according to the legend: Color the monitor in black, keyboard in grey.

Don t overdo (1-6, 1-7). General carefulness What must to be covered in each lesson The correct procedure/order to switch on the computer The correct procedure to switch off the computer [Not directly switch off the power] Shutdown procedure No banging [Care of computer accessories] Emphasis: Correct procedure to switch off What other optional topics may also be covered It needs power to run Ideally switch off the computer if it is not being used: to save power Probable error messages while switching on What if the PC does not start?

3 similarly computers need power to start Illustrations for showing the computer in the on mode / off mode What happens when you switch on the monitor first, but do not switch on the CPU: you will see a blank screen. If computer is not properly switched off, what is the message you get when you switch on next [ shut down was not done properly the last time, it will start some auto check of hard disk..] Suggestions for worksheets Ask the student to start the computer by himself/herself How many places do they have to switch on [power plug, CPU, monitor] Jumble the order of switching and ask the student to put it in order [ even though the order is not critical..] The student should be asked to shut down the computer Pointers to existing contents (1-10,1-11, ). Introduction to Keyboard What must to be covered in each lesson Function of a keyboard [Input to the computer] :

Difference between inputs through keyboard and mouse. The mouse allows us to define the starting point for any activity/action [ eg : double click an application / entry through a Keyboard ]. What other optional topics may also be covered Mouse properties like : button, pointer settings can be changed By default, mouse is for right handed students Settings can be changed to suit left handed students Any suggestions for the detailing / lesson plan Handling the mouse Mouse should be kept on the mouse pad When is a right click / left click / double click used Correct way to hold a mouse : index finger on the left button, middle finger on the right button Position of the mouse is to the right of the keyboard Suggestions for worksheets Illustration of a mouse and the student writes the parts of the mouse Where is the cord? : This is a cordless mouse What is this? Pointer on the monitor What is this? I The Cursor on the monitor How many buttons are there on a mouse? What is the scroll button used for? What else can be used to go up/ down a page?
