Studies of advanced expertise development in a number of areas are reviewed in order to provide general suggestions about the elements of clinical training that might enhance counseling and educational psychology expertise. The emphasis of the discussion is on the connections between classroom instruction and practicum or internship experiences. Recommendations include changes in the sequencing, context, knowledge content, practice conditions, and motivational support provided to students. 相似文献

The matching cloze procedure, which does not require language production skills and which is simple enough for the classroom teacher to construct unaided, was originally developed to measure reading skills of elementary English‐second‐language pupils. The results of this pilot study with opportunity school children indicate the validity of the procedure as an evaluation technique for slow learning children. 相似文献

Research in Science Education - Students learn more than science knowledge in a science classroom; they also acquire important messages about the purposes and contexts of science. Roberts (2011)... 相似文献

Pigeons pecked on three keys, responses to one of which could be reinforced after 3 flashes of the houselight, to a second
key after 6, and to a third key after 12. The flashes were arranged according to variable-interval schedules. Response allocation
among the keys was a function of the number of flashes. When flashes were omitted, transitions occurred very late. Increasing
flash duration produced a leftward shift in the transitions along a number axis. Increasing reinforcement probability produced
a leftward shift, and decreasing reinforcement probability produced a rightward shift. Intermixing different flash rates within
sessions separated allocations: Faster flash rates shifted the functions sooner in real time, but later in terms of flash
count, and conversely for slower flash rates. A model of control by fading memories of number and time was proposed. 相似文献

Designing Instructional Examples to Reduce Intrinsic Cognitive Load: Molar versus Modular Presentation of Solution Procedures 总被引:2,自引:1,他引:2
It is usually assumed that successful problemsolving in knowledge-rich domains depends onthe availability of abstract problem-typeschemas whose acquisition can be supported bypresenting students with worked examples.Conventionally designed worked examples oftenfocus on information that is related to themain components of problem-type schemas, namelyon information related to problem-categorymembership, structural task features, andcategory-specific solution procedures. However,studying these examples might be cognitivelydemanding because it requires learners tosimultaneously hold active a substantial amountof information in working memory. In ourresearch, we try to reduce intrinsic cognitiveload in example-based learning by shifting thelevel of presenting and explaining solutionprocedures from a `molar' view – that focuseson problem categories and their associatedoverall solution procedures – to a more`modular' view where complex solutions arebroken down into smaller meaningful solutionelements that can be conveyed separately. Wereview findings from five of our own studiesthat yield evidence for the fact thatprocessing modular examples is associated witha lower degree of intrinsic cognitive load andthus, improves learning. 相似文献
