I'm trying to put together a list of educational software applications that are more than drilling exercises or trial-and-error. So far I found only a handful, surprised by how few there seem to be! So I throw the question out there: what educational software do you know of, that has been used in regular classrooms for a specific topic? Note: I'm not looking for just technological "tools" or resources that assume a task defined by the teacher, but applications that work more or less independently for training knowledge or a skill within the curriculum (e.g. biology, history, languages, math, however math seems heavily overrepresented). Target age group 4-15, possibly up to 19 years. Some good, well-documented examples I found are Betty's brain, SimStudent and Critter Corral (for young children). Surely there must be more, e.g. for training foreign languages? I'm very grateful for tips & if possible links where one can try the software!
