Ogunsola-Bandele, Mercy F.; Lawan, Falilatu K. – 1996
The purpose of this study was to analyze the errors made by high school students in practical biology and the extent to which boys and girls differ in terms of the frequency of errors committed. The subjects included 317 students from the twelfth grade sampled from five different schools in Nigeria. A criterion level of 0.05 was set to test the…

Taylor, Brett – Physics Teacher, 2006
Ping-Pong vacuum cannons, potato guns, and compressed air cannons are popular and dramatic demonstrations for lecture and lab. Students enjoy them for the spectacle, but they can also be used effectively to teach physics. Recently we have used a student-built compressed air cannon as a laboratory activity to investigate impulse, conservation of…
