The catch is that every quiz is different. Every time a student asks to take a quiz the site reaches back into a data bank for new questions. Wight has noticed a difference since he has instituted the electronic quiz into his chemistry class. If they have taken an electronic quiz before class then they are prepared to ask questions. Without the quizzes, no matter how much you beg and plead, they will not have read the material before class.
Students submit homework through a similar process.
They download the assignment from Wight's website, then produce answers to the questions and enter them in the spaces provided on the web page. The website grades the homework instantly and the student then has the option to correct wrong answers. After the due date the website releases the correct answers and the methods the professor used to solve the problems. Wight believes that his system alerts students to potential problems in their homework sooner than the traditional method. It is interesting to note that Wight says he has not had to teach a student how to use the Internet for two years.
