The measure of a proficient typist does not rely solely on the speed of their typing. There are many ways of illustrating the importance of this fact for your students who may be focused on being the fastest typist in class. Consider imparting rules for calculating typing proficiency. In times past, when typewriter typists were tested on their ability, their WPM score was reduced by 10 for every mistake made within a minute long test. So a speedy typer may clock in at 50 WPM but make 3 mistakes, dragging their overall score down to 20 WPM. Establishing rules such as these in class will entice your more ambitious students to take their time, thus ensuring good typing practice habits. You can also dictate what students should be typing rather than have them type out words on the screen. This will force students to stay at the speed you’re speaking, allowing them to focus solely on accuracy.
