Greetings from Argentina. The problem is, he says, that some things help students learn better than others. Peter Kandlbinder then further clarifies his point.
People help other people learn, often using a range of technologies.
There already are some proven strategies that let us evaluate this process, which he thinks need to be the starting point for any evaluation system. If this is the reality of good teaching, then there is no alternative but to transfer the same good teaching practice to on-line learning as well. We must support open standards that operate at a low level, standards that are enabling rather than restricting, he concludes. Mike Collet thinks it is important to differentiate between open and proprietary or de facto, and between standards and specifications. It is important that any learning technology standards are open for several reasons, including avoiding vendor lock-in.
