I know that it’s difficult for teachers to come up with novel approaches that engage students. It’s tough. Parents look at school as a place to dump their children while they are off doing whatever it is that they do during the day time. Schools are left to attempt to cram some knowledge into the young skulls and usually fail.
There may be as many as 30 seventh grade students from Redwood City (a posh suburb south of San Francisco) that will need to get tested for hepatitis and HIV because a stupid substitute science teacher thought it would be a good idea to use the same lancet over and over again. Even the students questioned the wisdom of the sub’s “protocol” and expressed concern over getting AIDS. According to the story in the San Francisco Chronicle, the teacher has been fired. The teacher will be lucky if he isn’t sued into oblivion and arrested on assault charges.
