This article advances the view that propositional logic can and should be taught within general education logic courses in ways that emphasizes its practical usefulness, much beyond what commonly occurs in logic textbooks. Discussion and examples of this relevance include database searching, understanding structured documents, and integrating concepts of proof construction with argument analysis. The underlying rationale for this approach is shown to have import for questions concerning the design of logic courses, textbooks, and the general education curriculum, particularly the (...) sequencing of formal and informal logic courses.

A number of national educational organizations and individual authors have called for the use of information technology to radically reform higher education. Several projections of how this reformation will unfold are presented here. Three different approaches to critically assessing these projections are considered in this article, two briefly and one in more detail. Brief consideration is given to an approach based on educational values and to an approach based on cost/benefit analysis. After some discussion of the strengths and weaknesses of (...) these approaches, a third approach deriving from a theory of technology control (Incrementalism) is elaborated in more detail and is found to offer helpful criticisms of the called for revolution in higher education. Some recommendations for how these new technologies can be developed in responsible ways are also offered. (shrink)

Rather than being random deviation, student errors can be a source of insight into the nature of student difficulties. This paper reports on (and offers pedagogical advice concerning) many common student errors in the construction of proofs, in the application of inference and replacement rules, and in the choice of proof strategies. In addition, a detailed description of the bottom-up strategy for “working backwards” is supplied, along with a discussion of the main difficulties students face when trying to solve proofs (...) in this fashion. Ultimately, it is argued that students can employ both top-down and bottom-up proofs strategies by making use of a graphic proof representation. (shrink)

This article traces the connection between expert systems used as consultants in medicine and their design for instructional purposes in education. It is suggested that there are important differences between these applications. Recognizing these differences leads to the view that the development of intelligent computer-assisted instructions (ICAI) should be guided by empirical research into social/psychological consequences and by ethical inquiries into the acceptability of those consequences. Three proposals are put forward: (1) that the pedagogical role of intelligent CAI be clarified, (...) (2) that forms of intelligent CAI be developed that aim primarily at refining rather than replacing human judgements, and (3) that ICAI research and development projects contain components which address ethical and social/psychological components and which are equitably-funded, integral parts of the overall development effort.

Predictions concerning postindustrial society include that of workers serving as machine monitors. That concept is explored in this article in respect to faculty in higher education serving as monitors of computers that are executing instructional programs. Questions concerning changes in faculty roles and the control of educational quality are addressed. Alfred Bork’s vision of asynchronous learning systems is elaborated, and that alternative is compared to the concept of machine monitoring. It is concluded that monitoring in higher education is not likely (...) unless student demand for distance learning is great, but in that case, monitoring would be superior to proposals for automated asynchronous learning systems.
