This book is a great resource for both teachers in teacher-training programs and working teachers. The book approaches TML from a constructivist perspective.
I particularly enjoyed their analysis of technology:
Learning Technologies:
- are more than hardware
- are any environment or definable set of (constructivist) activities
- are not conveyors or communicators of meaning
- support meaningful learning when they fulfill a learning need
* learners and technologies should be intellectual partners, where the cognitive responsibility for performance is distributed to the partner that performs it better (p.6)
