Causal modeling was used to examine how primary students' language ability interacted with pace and redundancy of instructional language during an expository science lesson to explain students' attention and learning. Language ability and pace, mediated by students' attention to the lesson, accounted for variance in learning outcomes. Higher…

A central theme of research on human development and psychopathology is whether a therapeutic intervention or a turning-point event, such as a family break-up, alters the trajectory of the behavior under study. This paper lays out and applies a method for using observational longitudinal data to make more confident causal inferences about the…

This paper uses the widespread variation across states in the timing of adoption of tougher drunk driving laws that set very low legal blood alcohol limits for drivers under age 21--"zero tolerance" (ZT) laws--to provide new evidence on the causal effect of alcohol use on youth suicide. ZT laws reduced heavy episodic drinking by underage men, with…

This paper proposes a model of learning dynamics and learning energy, one that analyzes learning systems scientifically. This model makes response to the learner action by means of some equations relating to learning dynamics, learning energy, learning speed, learning force, and learning acceleration, which is analogous to the notion of Newtonian…

This paper addresses the accumulating knowledge of prospective teachers of secondary school mathematics and their acquired proficiency during the course "Psychological aspects of mathematics education," in which we discussed theoretical models including the intuitive rules theory. Participants' performances are examined by means of an extensive…

By making visible certain entities, phenomena, changes and continuities as being relevant to vocational education, researchers are joint definers of work and education at their sub-national, national and supranational levels. Which stories and mappings are going to have currency in transnational discourses on VET? Studies about transformation of…

This article argues that an important source of the difficulties posed by particular concepts and theories is the narrow range of "types of causal models" with which most learners are familiar. Most learners are familiar with relatively simple styles of causal models, but many concepts and theories in science depend on styles…

The purpose of this article is to discuss determinants of computer self-efficacy from the perspective of participant internal learning motivations and external learning environments. The former consisted of three motivations--interest, trend, and employment--while the latter comprised two environments--home and school. Through an intermediate…

Rather than studying the structural paths through which variables affect student persistence in education, this paper offers a reduced form model that focuses on precollege, demographic, and certain current achievement and financial aid variables. This approach does not specify structural paths, but it does have the advantage of requiring only…

Abuses and misuses of statistics are frequent. This digest attempts to warn against these in three broad classes of pitfalls: sources of bias, errors of methodology, and misinterpretation of results. Sources of bias are conditions or circumstances that affect the external validity of statistical results. In order for a researcher to make…

This digest illustrates the variety of basic and theoretical issues in evaluation with which aspiring evaluators should be conversant in order to claim that they know the knowledge base of their profession. Coverage of the issues includes: the four steps in the logic of evaluation; whether qualitative evaluations are valid; whether it matters if…

The causes of bigotry, prejudice, and hatred and what can be done about them are discussed by the authors represented in this collection. Most of the book provides general discussions of these issues, but Part 2, "Universities and the 'Politically Correct' Response to Hatred and Prejudice," contains some specific examinations of these…

This study investigated gender differences in causal attributions and emotions to success and failure. A literature review on gender differences in causal attributions revealed inconsistencies. For the present study, college students (N=247) filled out questionnaires and were also asked to imagine varying degrees of success in college courses. The…

Examined whether children's causality beliefs about school performance show similar developmental profiles across six distinct sociocultural settings. Found markedly similar developmental patterns in their beliefs about the importance of effort, ability, luck, teachers, and unknown factors as influences on school performance. Found that factors…

Two experiments used causal models to examine possible relationships among age, learning rates, learning opportunities and forgetting rates. Found that forgetting rates declined markedly between early and late childhood. (ET)
