Typing on a Computer Keyboard. For some students, learning to type on a computer can be as difficult a task as learning to write with a pencil. Students with good fine motor skills are often better at mastering this particular skill. Typing requires coordinating finger movements and memory skills. A student must first remember where the letters, numbers, and symbols are located on the keyboard.
Remember, keyboarding accuracy is just as important as speed, so don't rush through the typing exercise. You may also create a free typing lesson account that will allow you to store your typing test results and provide performance graphs, so you can monitor your own typing skill improvement over time.
