A Cognitive Approach to Design Case for e-Learning
Though powerful as a cognitive processing tool, the working memory is inhibited by its limited capacity and limited duration.In this paper we have presented an open and dynamic model of design case for elearning by the Deming spiral, as organizational tool.Learning scaffold may be used in design case for e-learning.Scaffolding strategies can be adapted to support students cognitive and metacognitive skills.A goal-free problem reduces extraneous cognitive load and aids in schema construction. Learners with worked examples of problems to study can be just as or even more effective in building schemas and performance transfer than having them work out similar problems themselves.There are three levels: cognitive presence, social presence, teaching presence in design online learning community. Optimization means trying to decrease entropy of resources.It is effective for decrease entropy to reduce cognitive load.
