Comparing split keyboards and normal keyboards
The materials required for this science fair project:
- 20 students who regularly type everyday, for at least 2 hours
- 30 typing assignments
- 5 computers with normal keyboards
- 5 computers with split keyboards
- 1 stopwatch
1. For this science fair project, the independent variable is the type of keyboard used. The dependent variable is the speed of typing, at the end of the month allocated for preparation/trianing. This is determined by using a stopwatch to count the words typed in 10 minutes and dividing the result by 10 to obtain words typed per minute. The constants (control variables) are the length of time allocated for practisingduring each session and the number of days for which the students continued practising.
2. 20 students who do regularly type everyday are selected. Their speed of typing is assessed on the first day of the science fair project using the normal keyboard. This is done by having the students type continuously for 10 minutes. At the end of the 10 minutes, the number of words typed is counted and divided by 10 to obtain the words typed per minute.
3. The students are then divided into 2 groups so that the average typing speed is almost the same for the students in both groups.
4. The students in the first group will continue to use the standard keyboard to practice typing assignments for an hour, for the next 30 days.
5. The students in the second group are introduced to the split keyboard. They practice typing assignments using the split keyboard for 1 hour for the next 30 days.
6. At the end of the 30 days, the 20 students are tested again for their typing speed. The first group is tested on the normal keyboard while the second group is tested on the split keyboard.
7. Their typing speeds are calculated and recorded in the table given below.
