Research investigating the role of computers in the primary classroom is closely linked to the body of knowledge concerned with theories of learning and child development. Research is presented as an attempt to provide scientifically supportable reasons why computers are effective in education. Having established a theoretical base for computer use in primary classrooms, this paper then examines the educational application of cognitive theory to classroom instruction. 相似文献

Third-year College Retention and Transfer: Effects of Academic Performance, Motivation, and Social Connectedness 总被引:1,自引:0,他引:1

We studied the effects of academic performance, motivation, and social connectedness on third-year retention, transfer, and
dropout behavior. To accommodate the three outcome categories and nesting of data within institutions, we fit a hierarchical
multinomial logistic regression path model with first-year academic performance as a mediating effect. Our sample included
6,872 students representing 23 four-year universities and colleges. This work expands the current state of persistence research
by (1) considering the effects of motivation and social connectedness on college persistence beyond the first year of college,
(2) testing whether the effects of motivation and social connectedness on third-year retention and transfer are direct, indirect,
or both, and (3) testing whether the effects of academic performance, motivation, and social connectedness are different for
retention and transfer. We found that academic performance has large effects on likelihood of retention and transfer; academic
self-discipline, pre-college academic performance, and pre-college educational development have indirect effects on retention
and transfer; and college commitment and social connectedness have direct effects on retention. Academic self-discipline led
to greater first-year academic performance, which suppressed its effect on retention and transfer. Practical and theoretical
implications of these findings and directions for future research are discussed.
A previous version of this paper was presented at the 2nd Annual National Symposium on Student Retention, Albuquerque, New
Mexico, October 2006. 相似文献

The ability to vote online has the potential to increase voter turnout for elections due to increased convenience over traditional voting polls. This study examines factors that can affect a citizen's intent to vote online. Survey subjects came from two different age groups: young adults, 18–25 years of age; and senior citizens, ages 60 plus. Using the Unified Theory of Acceptance and Use of Technology (UTAUT), the study found that performance expectancy, effort expectancy, social influence, trust in the internet, and computer anxiety were significantly related to intent to use online voting. Trust in the government was insignificant. Performance expectancy, social influence, and computer anxiety were related to intent to vote online for both young adults and seniors. Effort expectancy was related to intent to vote for the seniors but not young adults, and trust in the internet was related to intent to vote for young adults but not seniors. 相似文献

Adolescent success providing satisfying support in response to a close friend's call in a caregiving task was examined as a potentially fundamental developmental competence likely to predict future social functioning, adult caregiving security, and physical health. Adolescents (86 males, 98 females; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other) were followed from ages 13 to 33 (1998–2021) using multiple methods and reporters. Early caregiving success was found to predict greater self- and partner-reported caregiving security, lower negativity in adult relationships, and higher adult vagal tone. Results are interpreted as advancing our understanding beyond simply recognizing that adolescent friendships have long-term import, to now identifying specific capacities within friendships that are linked to longer-term outcomes. 相似文献

Floating is the act of staff moving from one unit to another based on the needs of the patients in a hospital. Many staff who float to different units express negative feelings, including anxiety and lack of self‐efficacy. However, floating is an economical and efficient method to use staff across the hospital, especially with current staffing shortages in the United States. This study investigated how the use of mobile performance support devices may help reduce anxiety and increase self‐efficacy for staff who float to different units. With access to multiple resources available on mobile devices, Bandura's social learning theory and self‐efficacy concept set the framework through modeling, observing, and imitating others in order to reproduce certain behaviors and tasks and believe in one's capability to perform. A quantitative study incorporating the retrospective pretest‐posttest design was conducted using the population of float staff, both nurses and respiratory therapists, from Children's Medical Center of Dallas. Both the State‐Trait Anxiety Inventory and General Self‐Efficacy Scale, along with a basic demographic tool, were used to explore anxiety and self‐efficacy in relation to the use of mobile performance support devices. Findings can be used to alleviate the negative feelings of staff toward the idea of floating. 相似文献

Abstract Interactive museum exhibits are ubiquitous in science centers, and are becoming increasingly popular in art, history and cultural museums. At an interactive exhibit, visitors can act on the exhibit and the exhibit reacts. While there is much theoretical and empirical support for the idea that interactive features promote science learning, we believe that serious design problems can arise if an uncritical “more is better” approach is taken to interactivity. This article describes five common pitfalls of designing exhibits with high levels of interactivity or multiple interactive features: 1) multiple options with equal salience, 2) features allowing multiple users to interfere with one another, 3) options that encourage users to disrupt the phenomenon being displayed, 4) features that make the critical phenomenon difficult to find, and 5) secondary features that obscure the primary feature. Examples of each of the five problems are presented, and possible design solutions are offered. 相似文献
