Education courses, even science education courses, tend to deal with the teaching process rather than content specifics. With support from the National Science Foundation, a series of 18 1-credit hour courses for chemistry teachers is appearing online. These courses have a public component. Anyone can access nearly all of the materials in these courses, and take the tests. All of the testing is online, with immediate, performance related feedback provided for all except essay assessment items.
Questions are in several formats including multiple choice, short answer, and essay.
Multiple choice and short answer questions are graded automatically. Essay items may be submitted for grading by registered students only. All users are provided immediate feedback. Model answers are provided for essay questions. The multiple choice and short answer questions are produced automatically, taking several elements from a database and mixing them up to produce randomly generated questions.
