Cognitive load theory is intended to provide instructional strategies derived from experimental, cognitive load effects. Each
effect is based on our knowledge of human cognitive architecture, primarily the limited capacity and duration of a human working
memory. These limitations are ameliorated by changes in long-term memory associated with learning. Initially, cognitive load
theory's view of human cognitive architecture was assumed to apply to all categories of information. Based on Geary’s (Educational Psychologist 43, 179–195 2008; 2011) evolutionary account of educational psychology, this interpretation of human cognitive architecture requires amendment.
Working memory limitations may be critical only when acquiring novel information based on culturally important knowledge that
we have not specifically evolved to acquire. Cultural knowledge is known as biologically secondary information. Working memory
limitations may have reduced significance when acquiring novel information that the human brain specifically has evolved to
process, known as biologically primary information. If biologically primary information is less affected by working memory
limitations than biologically secondary information, it may be advantageous to use primary information to assist in the acquisition
of secondary information. In this article, we suggest that several cognitive load effects rely on biologically primary knowledge
being used to facilitate the acquisition of biologically secondary knowledge. We indicate how incorporating an evolutionary
view of human cognitive architecture can provide cognitive load researchers with novel perspectives of their findings and
discuss some of the practical implications of this view. 相似文献

Many innovative teaching approaches lack classroom impact because teachers consider the proposals impractical. Making a teaching approach practical requires instrumentality (procedures), congruence (local fit), and affordable cost (limited time and resources).This paper concerns a study on the development and effects of a participatory design based teacher training trajectory aimed at making guided discovery learning (GDL) practical for student biology teachers. First, we identified practical heuristics for designing GDL lessons by analyzing design protocols made by biology teachers who are experts in GDL. Next we inventoried student responses to their regular lessons and to GDL based lessons. Based on this we prepared a teacher training program for eleven student biology teachers in which they applied the heuristics and stepwise extended their teaching repertoire in the direction of GDL. The participants’ design processes and resulting lesson plans were scored on both use of design heuristics and GDL characteristics. The participants were interviewed about their motivational beliefs before and after the program. Results showed that student teachers are able to design GDL lessons and used the heuristics to design GDL lessons. Their motivation for implementing GDL in their classroom had increased substantially. The paper concludes with a critical reflection on our method of participatory design and its applicability. 相似文献

Training for reflective expertise: A four-component instructional design model for complex cognitive skills 总被引:2,自引:0,他引:2

This article presents a four-component instructional design model for the training of complex cognitive skills. In the analysis
phase, the skill is decomposed into a set of recurrent skills that remain consistent over problem situations and a set of
nonrecurrent skills that require variable performance over situations. In the design phase, two components relate to the design
of practice; they pertain to the conditions under which practice leads either to rule automation during the performance of
recurrent skills or to schema acquisition during the performance of nonrecurrent skills. The other two components relate to
the design of information presentation; they pertain to the presentation of information that supports the performance of either
recurrent or nonrecurrent skills. The basic prediction of the model is that its application leads to “reflective expertise”
and increased performance on transfer tasks. Applications of the model that support this prediction are briefly discussed
for the training of fault management in process industry, computer programming, and statistical analysis. 相似文献

Although the concept of mentoring is receiving increasing attention in the counseling field, the intersection between multiculturalism
and mentoring has not been formally addressed. This article explores mentoring relationships between faculty and students
within counselor education from a multicultural perspective. Semi-structured interviews were used to explore African American,
Asian American and Latina/o American counselor education graduate students’ perspectives on mentoring. Three similar themes
(trust/comfort/honesty; respect; and teacher/student/guide) emerged for all three racial/ethnic groups as important key elements
in the mentoring relationship, but with some distinctive culturally relevant variations in emphasis. Also, all three groups
to some degree reported that having a mentor who was culturally competent and sensitive was helpful, adding further weight
to the view that cultural issues play a role in mentoring relationships. Implications of the findings are discussed. 相似文献

Thirty aquatic diving beetles,Rhantus atncolor, of the family Dytiscidae, were subjected to 1-, 5-, 10-, 15-, 20-, and 25-min levels of oxygen deprivation. The level of deprivation was procured by submerging the Ss under water for the allotted period of time. A control group receiving no oxygen deprivation was also tested. The results clearly established oxygen deprivation as a drive state capable of increasing the general level of activity in aquatic Coleoptera as measured by swimming speed in the runway. Significant differences were also found between these deprivation levels. 相似文献

Science education researchers have, with few exceptions, not used the conceptual content of science as an important variable in their research. Writings of two groups-philosophers of science, “are concerned with the influence of the conceptual knowledge shared by an intellectual community on the activities of that community and the psychologists are concerned with the influence of the conceptual knowledge held by an individual on that individual's behavior”, science, are concerned with the influence of the conceptual knowledge shared by an intellectual community on the activities of that community and the psychologists are concerned with the influence of the conceptual knowledge held by an individual on that individual's behavior. Suggestions are offered as to what kinds of science education research could be done in which the conceptual content of science is important. 相似文献

The research on worked examples has shown thatfor novices, studying worked examples is oftena more effective and efficient way of learningthan solving conventional problems. Thistheoretical paper argues that addingprocess-oriented information to worked examplescan further enhance transfer performance,especially for complex cognitive skills withmultiple possible solution paths.Process-oriented information refers to theprincipled (``why'') and strategic (``how'')information that experts use when solvingproblems. From a cognitive load perspective,studying the expert's ``why'' and ``how''information can be seen as constituting agermane cognitive load, which can fosterstudents' understanding of the principles of adomain and the rationale behind the selectedoperators, and their knowledge about howexperts select a strategy, respectively. Issueswith regard to the design, implementation, andassessment of effects of process-orientedworked examples are discussed, as well as thequestions they raise for future research. 相似文献
