Comments to Chapter 10

Before to produce a e-learner unit, it is very important to analyze the unit content, the concepts, and the relation between them to decide how these will be designed. Our work is to simplify the information complexity to learners. According to some cognitive theories, human memory has limits. Learners could not process unfamiliar information and complex conceptual relation because their cognitive system becomes overloaded.
To avoid this problem, we have to learn how to applied two principles: segmentation and pretraining. When we have material that are complex to understand, we have to broke the material into short segments, lighted his concepts, and to show the relation between them. The second principle is pre-training. It is well know that nobody could understand and remember huge amounts of unfamiliar information. According to Mayer and Chandler (2001,) “learners who received the segmented presentation on lightning formation preformed better on transfers tests than learners who received a continues presentation…”
Segmenting and Pretraining are two principles that could apply daily to design our lesson plans, instructional multimedia materials, webpage and any others material used in e-learning. For me, these concepts are product of the application of the common sense.
We learn more if we are familiar whit the subject that we are study, and if the information is presented into bite-size segments. We cannot forget that learners learn more when they are able to identified concepts and his relations.
