In relating brain hemisphere differences to education and educational administration, the author reviews literature on the issue and discusses the concepts involved. For background, he briefly goes over the history of brain and cognition studies and the advent of "split-brain" studies and the "triune" brain theory. Definitions…

The philosophical roots of the concept of lifelong learning are considered in relation to the views of Socrates, Plato, and Aristotle. They pioneered in their analyses of intellectual development and in the importance of the use of the mind throughout the life span. Plato and Aristotle added metaphysical arguments to support their systems of…

Examines the differences between concrete and abstract concepts and their implications for instructional design and teaching. How specific concepts are stored in and retrieved from memory is described, analogies are discussed as an instructional tool in abstract concept learning, and a possible instructional strategy for teaching abstract concepts…

Examines a high school literature censorship case, and challenges the assumption that values can be "absorbed" through emotional engagement with a "transparent" text. Concludes with guidelines for avoiding indoctrination by viewing literature as the construction of fictional worlds whose values are decoded by calculated acts of…

This defense of the authors' previous report states that there is a large sex difference in mathematical reasoning ability among intellectually talented preadolescents. The authors concluded differential course taking could not account for observed sex differences among intellectually gifted students, although this may affect average ability…

Many science curriculum development projects have the goal of increasing students' ability to employ scientific or formal reasoning strategies. Argues that longitudinal data of students who acquired formal reasoning strategies as a consequence of specific instruction are needed to provide evidence that these skills will help in other academic…

Even among individuals operating at Piaget's highest cognitive level (Formal Operations Stage) there is a range of behaviors on important cognitive characteristics. Various substages and their performance criteria are suggested. (JD)

Discusses the tutorial process in problem-based learning (PBL) and how it can be used to cultivate higher order thinking skills. Considers the role of the problem, collaboration among peers, the facilitator role, and the importance of student reflection. PBL principles are applied to instruction of gifted students. (DB)

The challenge for education in today's knowledge age is developing students' capacity for sustained creative work with ideas. Although even the youngest students don't fear the abstract, working to improve ideas is an acquired disposition. Creative production is a progressive design process. Software is described in which students, as a community,…

Conventional instruction in critical thinking may ignore the creative and intuitive functions of rationality, thereby encouraging a mechanically rote approach to textual analysis, problem solving, and problem construction. Such an overemphasis upon logical "calculus of justification" functions has epistemological weaknesses and pedagogical…

Refutes Peter Mueser's criticisms of the author's position on formalistic research approaches. Restates that statistical significance is virtually useless. Claims mathematical economists take their intellectual positions from mathematics departments bringing irrelevant intellectual values into economics. (NL)

Considers Richard Ohmann's argument that composition texts which instruct students to emphasize concrete details over abstract concepts encourage conformity with the dominant order. Suggests that Ohmann failed to consider the effects of teachers' and students' viewpoints. Cites methods that encourage students to use detail as a device of broader…

It is argued that science's reputation as a "hard" subject can be attributed to four intrinsic features of science and/or learners. The reasons for a link between abstraction and difficulty are briefly explored. It is suggested that certain extrinsic features of science education, resulting from choices by science educators, exacerbate these…

Explains abductive reasoning; compares it to more traditional forms of logic, i.e., deduction and induction; and describes a computerized tutorial called A.R.T. (Abductive Reasoning Tool) that was created to foster abductive reasoning. Implications of using abductive techniques in instructional design are suggested. (Contains 13 references.) (LRW)

Argues that the limited results achieved so far by empirical educational research are a result of a fundamental difference in the generalized concepts used therein and the abstract concepts used in the natural sciences. Discusses the work of Galileo and Newton to clarify the difference between generalization and abstraction. (DMM)
