1. One minute papers

Main point

Affordances and various loads

Collaborative/competition load

Roles of patents in tech development

Questions

Can affordances be negative (e.g., google interface; classroom facilitations)?

If we (mind) are always looking for change (variety spice), how much is enough/too much?

Is games for learning driven by tech or are we seeing examples of learning goals drive game development?

Can we monitor/sense user needs/states and automatically provide better search support?

How to demonstrate potential of gaming in education (beyond simulation)?

What other levels of involvement/load are there? (e.g., spiritual?)
