This study's purpose was to determine whether science teaching self-efficacy beliefs among new teachers of elementary science interact significantly with teaching environments in their schools. The study hypothesized a mechanism by which environments can interact with self-efficacy and, consequently, affect the quality of science teaching. The…

The present study examined a longitudinal model of state and trait negative affect as predictors of job-search success. Job-search self-efficacy and job-search intensity were also examined as mediators of the negative affect--job-search success relation. Overall the model offered mixed support for Kasl's (1982) Reverse Causation Hypothesis.…

Problem solving and social support, as different styles of coping with intergenerational family conflict, were examined among 86 Hmong American college students. Problem solving and social support were hypothesized to differentially moderate the effects of family conflict on psychological adjustment. Furthermore, the effects of attributions of…

We use a variation of contextual fear conditioning, called the context pre-exposure facilitation effect (CPFE) to study the rat's memory for context. In this paradigm, the rat is pre-exposed to a conditioning context and later returned to that context, where it is immediately shocked. The memory context is revealed by the fact that pre-exposure to…

Two experiments tested predictions from a theory in which processing load depends on relational complexity (RC), the number of variables related in a single decision. Tasks from six domains (transitivity, hierarchical classification, class inclusion, cardinality, relative-clause sentence comprehension, and hypothesis testing) were administered to…

Recent research has come a long way in describing the linguistic features of large samples of written texts, although a satisfactory description of L2 writing remains problematic. Even when variables such as proficiency, language background, topic, and audience have been controlled, straightforward predictive relationships between linguistic…

Purpose: The purpose of this paper is to examine how the way change implemented effects organizational learning. More specifically, we study the relationships between the use of social accounts, participation and organizational learning in the context of strategic change. The use of social accounts and participation are often promoted during…

Purpose: To deepen the understanding and to encourage further research on leadership best practices for sustaining quality improvement in UK higher education institutions (HEIs). Design/methodology/approach: The literature on leadership provides the theoretical context for the survey of quality managers from 42 UK HEIs. A mix of questionnaires,…

Because of criticisms leveled at statistical hypothesis testing, some researchers have argued that measures of effect size should replace the significance-testing practice. We contend that although effect-size measures have logical appeal, they are also associated with a number of limitations that may result in problematic interpretations of them…

Unless the sample encompasses a substantial portion of the population, the standard error of an estimator depends on the size of the sample, but not the size of the population. This is a crucial statistical insight that students find very counterintuitive. After trying several ways of convincing students of the validity of this principle, I have…

Research during the past decade lends support to the notion that visual as well as phonological deficits are significantly correlated with reading and learning disorders. However, from the variety of visual anomalies discussed, it soon becomes evident that vision, itself, is not a unitary disorder. In this review, the multifaceted nature of…

This paper summarizes research conducted on three computer based video models' effectiveness for learning based on memory and comprehension. In this quantitative study, a two-minute video presentation was created and played back in three different types of media players, for a sample of eighty-seven college freshman. The three players evaluated…

Self-concept and adjustment are two important psychological aspects influencing the personalities of individuals. The term self-concept refers to the individual's perception or view of himself. It refers to those perceptions, beliefs, feelings, attitudes, and values which the individual's perception of his abilities and his status and roles in the…

The present study investigated the pathways between attention problems and depressive symptoms, particularly the role of academic incompetence, among a community sample of urban African American children. Results supported the hypothesized path models from inattention to depressive symptoms for girls and boys. Academic performance in the spring of…

Purpose: This paper aims to demonstrate that students' self-evaluations contribute to improving academic results and life skills. Design/methodology/approach: Taking as reference a group of previously validated scales (part 1: measurement), a causal model is developed. Hypotheses are tested through the structural equations methodology by using the…
