Due to the video format, time for student questions isn't built into the course. Students should stop and review the presentation and consult the book when they have trouble with a concept. Technical support is also available by phone if students get stuck. To think concepts through, students really do need to stop the video occasionally to think it through and to try to solve example problems. For this reason, consider that some sessions might take up to double the lecture time to complete.
Students then work through problems in the text.
In fact, many colleges, including community colleges, require a one-unit computer class that is designed to coincide with each specific advanced math course in addition to the use of graphing calculators to solve upper level math. Chalkdust makes use of a graphing technology guide explaining how to use the different models of calculators from Texas Instruments, Casio, Sharp, and Hewlett Packard. Of course each calculator manufacturer also provides its own guidebook. It would be wise to consult with math departments of the colleges you are considering before making a purchase. It is recommended that if your student does not have experience in the use of graphing calculators that he becomes acquainted with its use using the manufacturer's guide before he takes the course.
