I'll try to answer your questions.
1. The materials are listed at the end of the lesson. Lessons also include a list of resources.
2. The steps are also in the lesson under Instructional Procedures. Additional tips are included when dealing with certain materials. You will be happy to know that the Visual Arts lessons are the first to include photos of processes and student work examples. Not all lessons have them but I know the Dream Space and Textile lessons do. There will be more in the upcoming sets.
3. What could not be included were photos or images of master works. Due to a variety of legal issues and the ever present copyright issue only reference could be made to suggested art work. Resources are provided and/or places to access the work. Also, only .org websites can be listed.
4. I hope I answered that in number 2.
Because the Standards are general and it is up to each teacher how to implement them in their curriculum, a scope and sequence is left to the individual district. There is talk of including a suggested curriculum map, as an example for the Identity lessons if the technology issues can be worked out. Your input will be passed on! The map will also be available at the workshops at the OAEA. Since I will be presenting it I will gladly share it here. Well, not here- people would have to email me for the attachment. It is an Excel worksheet.
re: more complete descriptions:
The PDF and Word downloads are pretty hefty. Did you find them?
Please let me know if you have any more questions.
