Background: The relation between academic self-concept and achievement has been examined in a large number of studies. The majority of these studies have found evidence for a reciprocal effects model. However, there is an ongoing debate on how students' achievement should be measured and whether the type of achievement indicator (grades, tests,…

Purpose: The study is a two-stage inquiry into the influence of high school principals and department chairpersons on the nature of science and mathematics teachers' community of practice participation. Of particular interest is the extent to which formal leaders influence the formation of productive communities of practice and the extent to which…

Presents instructions for playing "Widgets and Blasters," an educational game designed to illustrate the functioning of a competitive market and help students understand economic models. Explains that the aims of the activity are to encourage students to identify the pattern of price over time and analyze the pattern in terms of…

Uses five unusual indifference curve exercises to show how changing the jail sentence and changing the reward for good behavior can influence the crime rate. Recommends eliminating minimum sentencing while raising sentencing and increasing the rewards for good behavior. Includes illustrative graphs for each exercise. (MJP)

Students (n=59, ages 13-22) in classrooms for the educably mentally retarded were interviewed regarding their attitudes toward computer use in school settings. Results showed a variety of complex beliefs and opinions about computer usage. The majority of students liked using computers and felt they learned "more" when they used computers.…

Defines and illustrates basic concepts of dichotomous logistic regression (DLR) and presents strategies for teaching these concepts. Strategies include using analogies between ordinary least squares regression and logistic regression; illustrating concepts with contingency tables; and linking logistic regression concepts to interpretation of…

Examines two classes of production functions in which the long-run competitive equilibrium scale of the firm increases when the relative price of the dominant factor decreases. Compares these with a third class of production functions where the equilibrium scale is independent of the relative price of the dominant factor. (MJP)

Contends that recent developments in historical sociology emphasize the centrality of temporality to analysis and explanation. Illustrates how computer-assisted analysis of qualitative narrative can be used to develop generalizable causal interpretation of events. (CFR)

Describes a teaching activity that improves students' scientific reasoning by focusing attention on the causal, explanatory nature of psychological theories. Students learn and use an argument form called Inference to the Best Explanation (IBE). Includes examples of this technique and student responses to the course. (MJP)

Provides an exercise for introducing research methods to undergraduates. The students view a graph revealing that left-handed people are underrepresented in older age groups. Small group discussions attempt to explain this phenomenon. A follow-up class discussion focuses on the different approaches and methods available for interpreting the data.…

Criticizes the use of blame analysis rather than scientific analysis in sociological studies. Defines blame analysis as an approach to social science that (1) evaluates theories according to the extent that they blame protected groups; (2) equates cause with blame; (3) and rejects theoretical arguments that posit any causal role for the protected…

Describes an assignment where students chart the development of a film or literary character's racial identity according to theoretical models of identity development. Students found the exercise thought-provoking, intriguing, and informative. Includes outlines of the racial identity model and an examination of the issues raised during discussion.…

Illustrates how, using introductory-level microeconomic models, an instructor can show various economic theorists' explanations of short run employment and output fluctuations. Identifies the competing schools of thought as old Keynesian, new Keynesian, and new Classical (which includes real business cycle theorists). Includes illustrative graphs…

Rectifies the unsatisfactory textbook treatment of the finite-sample proprieties of estimators of regression models with a lagged dependent variable and autocorrelated disturbances. Maintains that the bias of the ordinary least squares estimator is determined by the dynamic and correlation effects. (MJP)

Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…
