CIT 710 Computers as Cognitive Tools Lionel G Smith
29663513
1. Briefly discuss conceptual change as seen by Jonassen. The cognitive process of adapting and reconstructing the theory that humans from an early age build simplified and intuitive personal theories to explain the world they live in and through experience they mature their theories as they learn, this is cognitive change. 2. Briefly explain Jonassen’s use of the term modeling. Modelling is used to externalise the understanding of subject matter and to give the learner the opportunity to build that what they are thinking of to assess if they understand it on both levels, cognitively as well as physically.
3. Briefly discuss the meaning of the word mindtool. Mindtools are computer tools that make the learner engage in facilitating cognitive processing. Cognitive tools support , guide, and extend the thinking processes of the learner. When using a
mindtool,
the
learner has to think harder. Mindtools facilitate learning and the meaning making process. 4. Briefly state the purpose of modelling. The teacher/facilitator can help the learners by building models of subject content using technology-based modelling tools to bring about a change in the learners. Jonassen indicates that the sole purpose of computers is to support meaningful learning. 5. Briefly discuss the modelling of domain knowledge, systems, thinking, problem solving and experiences. Domain knowledge is subject-matter expertise; knowledge about a specific field of interest; knowledge about a specific content area. Mind map or system modelling tools may be used.
6. Briefly discuss the limitations of mindtools. Three limitations of mindtools are: Cognitive load: Mindtools places a high load on the cognitive development of children. Developmental Differences: Some learners may not be on the cognitive level of others to be able do what the teacher expects them to do. Fidelity: Models are representations of interpretations of phenomena in the world not the objects themselves.
