Reconsidering the Textbook: Internet-based Alternatives
DTS Dissemination Project: GEORGIA 2006 Multivariable Calculus UGA Math Dept. Fundamentals of Geometry II, UGA College of Education
Brief History • 1968 - Hypertorus, Computer Calculus • 1975 - Salvador Dali and the NSF • 1978 - Hypercube Film, ICM Helsinki • 1980 - Hypersphere Slides, Star Trek • 1984 - “Flatland” to Hypergraphics • 1991 - Beyond the Third Dimension • 1994 - Internet-Based Geometry • 2000 - Math Awareness Month • 2002 - ICM Beijing, • 2004 - DTS, A&I at UGA
Overgrown Calculus Texts • Size: Over 1200 pages • Cost: Well over $120 • Aim: Treatment of all possible examples and problems. • Ancillaries: Specialized Problem Sets, CAS exercises, CAD exercises, automatic homework generation. • Linear, traditional, generic, encyclopedic, “one person’s tour of the domain”
Fundamental Challenge: Responsive Choice • Text as problem source • Text as additional examples • Altering order of topics • Skipping topics • Syllabus construction • Handbook for future reference
Fighting with the textbook • Notational preferences • Choice of proof(s) • Level of questions • All dimensions at once • Level of rigor • Illustration conventions • Background material
Desirable Qualities • Non-linearity • Modularity • Background Access • Forward Access • Spirality • Customizability • Expandibility
Features of a NewCourse • Time-Released Discussions • Timely Homeworks • Hints • In-process Dialogue • No More “I have no idea how to start” • Solution Key
Lab as Metaphor 1968 - Punchcards overnight 1975 - Video Demos in Diff. Geometry 1983 - DIAL animation language 1987 - EDGE, BUDGE 1991 - VECTOR, VENOM, DGEOM 1994 - Matrix 2003 - Tensor
Assignments • Semi-synchronous response • Multiple feedback
Discussions • Simplified math entry • Linking to sites and images
Labs • Interactive demos • Exploration of geometric phenomena
Resources • Adaptable • different disciplines • different backgrounds • teacher training
Tensor • Scalable • virtual recitations • interactive seminars
