Student perception is an essential component in education; especially in engineering courses, which involve complex spatial processes, manipulation and interpretation of graphs, diagrams, and concepts. Incorporation of special training instructions improve spatial skills of learners, assisting them to acquire enhanced conceptual knowledge. Through…

The authors argue that insufficient attention has been given to foundational concepts in special education. Two classes of foundational concepts are discussed: human constructions and logico-mathematical facts. Four human constructions are examined: (1) making teaching most important, (2) discriminating among ideas, (3) choosing conceptual models,…

This paper explores how models can support productive thinking. For us a model is a "thing", a tool to help make sense of something. We restrict attention to specific models for whole-number multiplication, hence the wording of the title. They support evolving thinking in large measure through the ways their users redesign them. They assume new…

In this article, the author describes an innovative approach for conceptualizing and managing career development tasks in the 21st century. Theoretical foundations and key concepts related to career flow theory are discussed.

Within the historical context of the development of chemistry, Avogadro's hypothesis represents a fundamental concept: It allowed Avogadro to explain Gay-Lussac's law of combining volumes and it allowed Cannizzaro to establish a more accurate set of atomic mass values. If students are going to understand the concept of relative atomic masses and…

A basic paradox is proposed: both freedom and determinism are seen as valid models although they are basically contradictory. Whether or not freedom or determinism is valid depends upon the source of information the person is using at that time. Implications of the paradox for counseling practices are discussed. (Author)

A general model for research in the concept of weight and other concepts is tested with second grade children. (Author/DEP)

The author discussed the role of three international organizations--UNESCO, Council of Europe, and Organisation for Economic Cooperation and Development--in the development and diffusion of knowledge of educational thinking. Three conceptual models (lifelong education, permanent education, and recurrent education) associated with these agencies…

Human infants are predisposed to organize their experience in terms of certain concepts (natural) and not others (unnatural). Three formal, necessary conditions on the naturalness of concepts are offered. The conditions attempt to link the problem of naturalness to principled distinctions between sense vs nonsense, simplicity vs complexity, and…

Presenting a general overview of career education in the United States, the author briefly reviews the historical development of career education in the American public education system, analyzes the components of career education, and examines it as a function of institutional type. He concludes that although postsecondary schools have been slow…

Analyzes attachment theory's viability as an overarching framework for counseling psychology. Places particular emphasis on the integrative potential and heuristic value of the theory, arguing that it can use biological (structural), psychological (cognitive/affective), and social dimensions of experience to clarify developmental dynamics in…

Investigates high school students' understanding of the physical relationship of chromosomes and genes as expressed in their conceptual models and in their ability to manipulate the models to explain solutions to dihybrid cross problems. Describes three typical models and three students' reasoning processes. Discusses four implications. (YP)

Theory and research regarding four levels of concept attainment and three uses of concepts as specified by the conceptual learning and development (CLD) model are described. The strategy and objectives of a longitudinal assessment of children's conceptual learning and development are presented. Perspective is provided regarding the role of the…

This paper presents a rationale for a disclosure approach to value analysis and describes the components of this approach, which involves student construction of value profiles of his own mythic thought, or mental framework, vis a vis a specified concept. The rationale is discussed in terms of the relationship between value study and mythic…

A basic first step in building a curriculum contributing to the orientation of youth to world of work is identification of concepts important to that orientation. In this study, the generalizations within the concept framework were identified through a developmental process of analysis and synthesis, including a review of current literature, a…
