6. 09/01/20166 Memory and Cognitive load John Sweller The purpose of this theory is highlighting characteristics and shortfalls of human memory; the aim is the development of more effective method for the assimilation of traditional and/or multimedia study materials. Indeed, any effective teaching can be developed only taking into account students cognitive abilities, paying special attention to the key functions of memory and to its limitations.

8. 09/01/20168 System deficits Information can be stored only in the long-term memory. Before being stored or used by the long-term memory, information needs to be processed by the working memory. But the working memory is extremely unsatisfactory both in its storage capacity (information processed per unit of time) and duration of storage period. In some circumstances, these information can impair knowledge Cognitive load

15. 09/01/201615 Three types of cognitive loads Intrinsic cognitive load Determined by interaction of type of didactic materials and level of student’s expertise Extraneous cognitive load Associated to processes not strictly related to the learning mechanism, and can be modified in the didactic method Relevant cognitive load Associated to processes strictly related to the learning mechanism as a mental frames building process. Carico load

16. 09/01/201616 The three types of cognitive loads are additive Having limited mental resources available, it’s necessary to decide how to distribute the cognitive lead among its three components. Intrinsic Cognitive Load Extraneous Cognitive Load Relevant Cognitive Load Total cognitive capacity Intrinsic Cognitive Load Extraneous Cognitive Load Relevant Cognitive Load Total cognitive capacity Cognitive load

18. 09/01/201618 Decrease Extraneous cognitive load Avoid: inappropriate examples overload of visual and auditory component irrelevant information Cognitive load

19. 09/01/201619 Increase Relevant cognitive load Encourage mental frames building number of problems to solve put in practice the acquired knowledge Cognitive load

20. 09/01/201620 Memorization of information and knowledge Tulving has advanced the hypothesis of at least three memory systems for processing different kind of information: the episodic memory the procedural memory the semantic memory

21. 09/01/201621 Episodic memory Our personal memories are related to episods, facts and experiences we are living.

22. 09/01/201622 The procedural memory is the memory system underneeth actions that require deftness: Explicit knowledge: what we are aware of knowing. Tacit knowledge: what we know without being aware of. Procedural memory

23. 1/9/201623 SEMANTIC MEMORY General knowledge we have, built as a result of deduction and induction processes in specific episodes; it is made of schemes, models, paradigms, propositions, programs, scripts. It starts building during the second year of life.
