Placing the computer monitor on top of the CPU case causes those muscles excess strain and should be avoided. Another issue is chair height. A child should look straight ahead or down at a 45-degree angle. Ideally, a fully adjustable chair should be used, but if that's not in the budget, Napper recommends that children sit on a piece of thick foam rubber. Another option for students whose feet don't touch the floor is an adjustable footstool.
Most mice are too large for students' hands.
Schools should have a variety of mice available so students can choose the most comfortable. Distance between keys and touch-pressure are concerns for smaller hands. Students should depress the keys lightly, which helps eliminate stresses on the fingers. Napper recommends portable keyboards, which tend to be smaller. When possible, Napper suggests, students should work standing, which keeps their feet on the floor, allows them to look down at the monitor, and keeps their bodies moving, thus helping to avoid repetitive stress injuries.
