O'Brien, Michael J.; Thompson, John R. – Physics Teacher, 2009
The Physics First movement--teaching a true physics course to ninth-grade students--is gaining popularity in high schools. There are several different rhetorical arguments for and against this movement, and it is quite controversial in physics education. However, there is no actual evidence to assess the success, or failure, of this substantial…

Kotsopoulos, Donna – Mathematics Teacher, 2007
As a result of frequently hearing students comment that the language used in mathematics is "like hearing a foreign language," the author investigated this perception by studying a ninth-grade mathematics classroom. Using transcriptions of classroom discussions and semistructured interviews with students, her findings suggest that students…
