Think of it as portable office hours! The Interactive Video Skillbuilder CD-ROM contains more than eight hours of video instruction. The problems worked during each video lesson are shown next to the viewing screen so that student can try working them before watching the solution. To help students evaluate their progress, each section contains a 10-question Web quiz (the results of which can be emailed to the instructor) and each chapter contains a chapter test, with answers to each problem on each test. Also includes MathCue Tutorial software. This dual-platform software presents and scores problems and tutor students by displaying annotated, step-by-step solutions. Problem sets may be customized as desired.
