Recent studies have tested the addition of worked examples to tutored problem solving, a more effective instructional approach than the untutored problem solving used in prior worked example research. These studies involved Cognitive Tutors, software designed to support problem solving while minimizing extraneous cognitive load by providing…

Purpose: To determine the incidence, associated consequences, and potential risk factors for horse-related injuries among youth and adults residing in Midwestern agricultural households.

Two studies of perceived and actual drug use at Simon Fraser University found students estimating greater drug use among friends than for themselves, but 31 percent reported dependence and 5 percent reported current addiction, especially to caffeine and nicotine. An approach to drug abuse focusing on familiar substances is recommended. (MSE)

In the present study, we analyzed mice with a targeted deletion of [beta]-catenin in DA neurons (DA-[beta]cat KO mice) to address the functional significance of this molecule in the shaping of synaptic responses associated with motor learning and following exposure to drugs of abuse. Relative to controls, DA-[beta]cat KO mice showed significant…

Seven papers from the 1988 CAUSE conference's Track I, Policy and Planning, are presented. They include: "Developing a Strategic Plan for Academic Computing" (Arthur S. Gloster II); "New Technologies Are Presenting a Crisis for Middle Management" (M. Lewis Temares and Ruben Lopez); "An Information Utility: The Light, Gas,…

Formative assessment has recently become a focus of renewed research as state and federal policy-makers realize that summative assessments have reached a point of diminishing returns as a tool for increasing student achievement. Consequently, supporters of large-scale testing programs are now beginning to consider the potential of formative…

Presents a multi-dimensional mediation model of student body composition effects that distinguishes between ability and status dimensions of composition and specifies the more proximate inter-personal and subjective mechanisms through which their consequences should operate. (Author/AM)

Designed to explore the determinants and long-range consequences of individual mobility in the U.S., the Explorations in Equality of Opportunity Project is a longitudinal survey of 2,077 students who were tested by the Educational Testing Service (ETS) as sophomores in 42 public high schools in 1955 and who were followed up by the Institute for…

This paper represents the preliminary analysis of a longitudinal data set well-suited for the study of educational and occupational attainment processes. The Blau and Duncan basic model is used. (Author/RM)

Parnes); "Creative Discipline: Entrepreneurial Objective or Oxymoron" (Arthur Lipper III); "Wowing Your Customers" (Stew Leonard); "Results of Recent Studies Examining the Effect of Need for Achievement and Other Variables upon…

Does where one goes to college depend upon the kind of high school attended? And, what are the consequences of attending a more or less academically selective college or university? These questions are evaluated separately for college men and women using longitudinal data from a national sample of youth who were high school sophomores in 1955. For…

Describes a multivariate model of high school to college transition and college attainment. Asserts that enrollment in a high status secondary school enhanced, for males, the likelihood of enrolling in an academically select college. States that college selectivity had no effect on females' educational attainment, but seemed to increase males'…
