Có nhiều bằng chứng cho thấy kiến thức chuyên môn dưới dạng các sơ đồ là yếu tố
chính phân biệt các chuyên gia với những người mới trong kỹ năng giải quyết vấn
đề. Bằng chứng cho thấy hoạt động giải quyết vấn đề truyền thống không hiệu quả
trong việc tiếp thu sơ đồ cũng đang gia tăng. Người ta cho rằng một lý do chính
cho sự không hiệu quả của giải quyết vấn đề như một công cụ học tập là do các

A theory of analogy must describe how the meaning of an analogy is derived from
the meanings of its parts. In the structure‐mapping theory, the interpretation
rules are characterized as implicit rules for mapping knowledge about a base
domain into a target domain. Two important features of the theory are (a) the
rules depend only on syntactic properties of the knowledge representation, and
not on ... hiện toàn bộ
Functional and mechanistic comparisons are made between several network models
of cognitive processing: competitive learning, interactive activation, adaptive
resonance, and back propagation. The starting point of this comparison is the
article of Rumelhart and Zipser (1985) on feature discovery through competitive
learning. All the models which Rumelhart and Zipser (1985) have described were

AbstractWe present statistical analyses of the large‐scale structure of 3 types
of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show
that they have a small‐world structure, characterized by sparse connectivity,
short average path lengths between words, and strong local clustering. In
addition, the distributions of the number of connections follow power laws that

A new diagnostic modeling system for automatically synthesizing a deep‐structure
model of a student's misconceptions or bugs in his basic mathematical skills
provides a mechanism for explaining why a student is making a mistake as opposed
to simply identifying the mistake. This report is divided into four sections:
The first provides examples of the problems that must be handled by a diagnostic

AbstractDespite the accumulation of substantial cognitive science research
relevant to education, there remains confusion and controversy in the
application of research to educational practice. In support of a more systematic
approach, we describe the Knowledge‐Learning‐Instruction (KLI) framework. KLI
promotes the emergence of instructional principles of high potential for
generality, while expli... hiện toàn bộ
We review the major phenomena of skilled typing and propose a model for the
control of the hands and fingers during typing. The model is based upon an
Activation‐Trigger‐Schema system in which a hierarchical structure of schemata
directs the selection of the letters to be typed and, then, controls the hand
and finger movements by a cooperative, relaxation algorithm. The interactions of
the pattern... hiện toàn bộ

AbstractThe authors examined cultural preferences for formal versus intuitive
reasoning among East Asian (Chinese and Korean), Asian American, and European
American university students. We investigated categorization (Studies 1 and 2),
conceptual structure (Study 3), and deductive reasoning (Studies 3 and 4). In
each study a cognitive conflict was activated between formal and intuitive
strategies ... hiện toàn bộ
AbstractWhen learning a new math concept, should learners be first taught the
concept and its associated procedures and then solve problems, or solve problems
first even if it leads to failure and then be taught the concept and the
procedures? Two randomized‐controlled studies found that both methods lead to
high levels of procedural knowledge. However, students who engaged in problem
solving befo... hiện toàn bộ
