The internet concept tests should be worked on by up to four students. A registered answer by a group will be recorded as 80 percent and if correct by 100 percent for each student. These do not differ much because it is the hope that these conceptual questions will be worked on and understood, or eventually understood, by everyone and the idea is to reward the effort and also gain experience in using the internet. Most of these examples will also be done during class. If possible a demonstration, or experiment, will be performed and additional questions posed and worked on by groups in class. Hopefully, class discussion will reveal the correct answers or at least an understanding of basic principles. Credit for classroom work will also be given at an additional percentage. The credits for all the Concept Tests will be 10% of the overall course grade. Some of these questions, or similar questions will be covered on regular hour exams and the final.
