A critical review of elaboration theory

In this article the authors examine elaboration theory (ET), a model for sequencing and organizing courses which was developed by Charles Reigeluth and associates in the late 1970s. The purpose of the article is to offer a critique of ET based on recent cognitive research and to offer suggestions for updating the model to reflect new knowledge.Commentary by Charles Reigeluth follows this article.     

Do Costs Differ Between For-Profit and Not-for-Profit Producers of Higher Education?

In theory, not-for-profit organizations will be characterized by higher production costs per unit of output than for-profit producers of otherwise-identical goods/services, since profit maximization implies cost minimization per unit of output; breaking even does not imply cost minimization and, indeed, may imply inflated costs. We explore the empirical validity of this hypothesis in the context of higher education. Using 1996 data, we estimate multiproduct cost functions for 1,450 public, 1,316 private, not-for-profit, and 176 private, for-profit institutions of higher education in the United States. We fail to find a statistically significant difference between for-profit and not-for-profit private providers, but do find a statistically significant difference between private, not-for-profit institutions and public institutions.     

Post-questioning, concept mapping and feedback: a distance education field experiment

This study was designed to assess the instructional potential of two learning strategies—post-questioning and concept mapping—in the presence and absence of systematic instructional feedback. It is a first attempt to test combinations of these treatments experimentally in the context of a course in distance education. Five research questions, drawn from the literature of post-questioning, concept mapping and feedback, were formulated to guide the design and analysis. Substantial differences in achievement outcomes were found for four of the five questions. These results are discussed in relation to the existing literature on outcomes of learning strategies and their implication for practice in distance education.     

Located in the thin of it: Young children’s use of thin moral concepts

One important socio-cultural medium through which young children’s moral understanding is cultivated is parent/child discourse. Of particular interest to us was young children’s use of basic (‘thin’) evaluative concepts (good, bad, right and wrong), which are ubiquitous in everyday discourse and serve as a potential bridge from the non-moral to the moral domain. We investigated 14 2–5-year-old children’s (and their parents’) use of thin evaluative concepts and found that while they frequently used good and bad to morally evaluate other people’s and their own psychological/dispositional states and behaviors—as well as, less frequently, to highlight relevant standards, expectations and rules—they did not use right and wrong. In contrast, a sample of US written and spoken public conversation revealed that adults did. Reasons for this are discussed, along with the frequency of different types of moral evaluations, differences between children and their parents, and age-related trends.     

Effects of processing instructions on the usefulness of a graphic organizer and structural cueing in text

This study assessed two adjuncts to instructional text, structural cueing and graphic organizer processing instructions. Previous research has shown that cueing is a useful indicator of textual structure and that graphic organizers can be enhanced by providing learners with an indication of how they can be used. Results indicated the presence of a three-way interaction among reading ability groups, structural cueing and graphic organizer processing instructions. Analysis of this interaction revealed that high level readers were the only subjects who profited from processing instructions, and only in the presence of cueing. Middle level readers benefited from cueing in both conditions of processing instructions while low level readers were able to take advantage of cueing only in the absence of processing instructions. The results are interpreted in light of previous graphic organizer research.
