Analyzes steady-state multiplicity in chemical reactors, focusing on the use of two mathematical tools, namely, the catastrophe theory and the singularity theory with a distinguished parameter. These tools can be used to determine the maximum number of possible solutions and the different types of bifurcation diagrams. (JN)

Outlines principles of evolutionary theory, including such recent changes as punctuated equilibria. Indicates that the incompleteness of Darwin's theory has been replaced with a conceptual framework and empirical information. Controversial issues remain, but the basic ideas still stand strong.

The range of problems associated with learned helplessness in mathematics is introduced through three hypothetical case studies. Then the basic theory of, the evidence for, and variables affecting learned helplessness are described. Issues of cure and prevention are discussed, and some suggestions are offered for teachers. (MNS)

Discusses effects on graduate sociology education of trends emphasizing quantitative methods and the positivist tradition at the expense of social theory and interpretive sociology. Argues that failure to develop sociology's interpretive tradition has allowed the style and intellectual creativity of sociological work to suffer. Urges greater…

Describes theory and a research program that uses guided reflection to promote the development of mentor teachers. Significant findings from a quasi-experimental study and a replication study are presented. The paper can assist teacher educators, policymakers, and school personnel who are searching for a teacher induction model. (GLR)

This resource guide for new student affairs professionals reflects on the socialization process experienced by new staff members and offers senior student affairs staff members and graduate preparation program faculty insights to assist them in designing programs for preservice students and new full-time staff appointees. "The New Professional"…

In distance education to date, the nature of teaching and learning in all academic domains has largely been understood in terms of behaviorist theories, more recently drawing on cognitive science from which principles and models for course design have been derived. This paper takes as its starting point contemporary critiques of such 'traditional'…
