The purpose was to promote the mediation of the thinking skills and heuristic processes of an expert working in a complex technology environment.b. Cognitive apprenticeship(認(rèn)知學(xué)徒) and

2、 the constructivist conception of learning were applied to organize the learning process.1、 Introduction：a. The recent demands for development of the school curriculum emphasize that learning seems to be both contextually bound and constructive in character.b. 也就是要促進(jìn)學(xué)生高層次的思考技巧(high level thinking sk

3、ills)及啟發(fā)式教學(xué)。c. However, the problem of how to convey thinking skills connected to high-level performances in practical learning situations, has remained largely unsolved.2、 Concept representations and mental models in direction of learning：a. According to the cognitive conception of learning, a succ

Mental modelthe representation of the students concept (theory or idea).Help students to identify the phenomenon or the situation.c. 學(xué)生是學(xué)習(xí)的主體，而非只是靠被傳授知識來學(xué)習(xí)。3、 Skilful problem so

Success problem solving include the ability to plan ones own action, to work forwards、backwards with the problem, the division of problem into subproblems.c. Experts are able to build larger solution models and plans in

The theory of cognitive apprenticeship has offered as a solution for making expert knowledge structure transparent and conveyable for the students.b. Applications of cognitive a

The learning environment：the automatic washing machineb. 3 hours each, during 3 weeks, 26 個13-

11、es- The boys programs include somewhat more nodes than those of the girlsb. The strategies of programming- Forward chaining vs backward chaining- 用圖解的方式讓學(xué)生將目標(biāo)分成子目標(biāo)，是希望他們可以用backward的方式來解決問題。- 以下以四組的情況來說明：(1) L組：u 一開始是backward chaining ，但沒有再細(xì)分下去完全backward chaining(2) M組：只要一個subprocedure完成便test。在spinin

Planning is linked to a situation graph helps to provide the experimentation phase with an organized procedural path that has some similarities to the behavior of an expert.b. Few groups of students were able to internalize(內(nèi)化) fully the modeled backward chaining approach, bu
