Radford University was recently configured with a campus-wide wireless local area network. Using these new capabilities, a classroom-based Honors section of Concepts of Biology was conducted solely using electronic technologies (paper was never transferred from professor to student). To accomplish this, students used common software and freeware. Commercial versions of similar software are designed solely for academic use, however, here the students were trained to use software and technologies that will be available to them once leaving the institution. Overall, students in this course responded favorably to the use of technology and reported that it aided in their learning process.  相似文献

Given the important role of parent-youth communication in adolescent well-being and quality of life, we sought to examine the relationship between specific communication variables and youth perceived quality of life in general and as a deaf or hard-of-hearing (DHH) individual. A convenience sample of 230 youth (mean age = 14.1, standard deviation = 2.2; 24% used sign only, 40% speech only, and 36% sign + speech) was surveyed on communication-related issues, generic and DHH-specific quality of life, and depression symptoms. Higher youth perception of their ability to understand parents' communication was significantly correlated with perceived quality of life as well as lower reported depressive symptoms and lower perceived stigma. Youth who use speech as their single mode of communication were more likely to report greater stigma associated with being DHH than youth who used both speech and sign. These findings demonstrate the importance of youths' perceptions of communication with their parents on generic and DHH-specific youth quality of life.  相似文献

This study examined the impact of computer simulation and supported science learning on a teacher’s understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers’ concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains, with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21) gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported science learning can have a positive effect on concept attainment in teachers.  相似文献

Pigeons pecked on three keys, responses to one of which could be reinforced after 3 flashes of the houselight, to a second key after 6, and to a third key after 12. The flashes were arranged according to variable-interval schedules. Response allocation among the keys was a function of the number of flashes. When flashes were omitted, transitions occurred very late. Increasing flash duration produced a leftward shift in the transitions along a number axis. Increasing reinforcement probability produced a leftward shift, and decreasing reinforcement probability produced a rightward shift. Intermixing different flash rates within sessions separated allocations: Faster flash rates shifted the functions sooner in real time, but later in terms of flash count, and conversely for slower flash rates. A model of control by fading memories of number and time was proposed.  相似文献

In this study, the researchers examined 5 years of Texas statewide data concerning elementary school size and Hispanic student performance on three state-mandated assessments in reading, mathematics, and writing. For each year of data analyzed here, student data from more than 1,200 elementary schools. After collapsing elementary schools into three sizes (i.e., very small <400 students; small 400–799 students; and large 800–1,199 students), multivariate statistical procedures revealed the presence of statistically significant differences in Hispanic student performance in reading, mathematics, and writing across all 5 years of data analyzed. In almost every analysis, Hispanic students in large elementary schools outperformed Hispanic students in very small elementary schools in reading, mathematics, and in writing. As such, our findings are in disagreement with other studies. Implications are discussed.  相似文献

If children are engaged in science lessons, their learning is likely to be better and, in the long term, careers in science and technology will remain open. Given that attitudes can develop early and be difficult to change, it is important for teachers of younger children to know how to foster engagement in science. This study identified what a cohort of 79 pre-service teachers in England considered to be engaging elementary science lessons and compared their notions with teacher behaviours known to be conducive to engagement. First, all brought beliefs about how to engage children in science lessons to their training. They tended to favour children’s hands-on activity as an effective means of fostering attentive participation in learning, although many had additional ideas. Nevertheless, the means and ends of their ‘pedagogies of engagement’ tended to be simple and narrow. Trainers need to ensure that notions of engagement are wide enough to cope with a variety of teaching situations, as when hands-on experience is not feasible, effective or appropriate. At the same time, teachers will need to recognise that one approach may not suit all learners. Without this, there is the risk that they will lack the skills to engage children in science. Nevertheless, these beliefs could offer a useful starting point for trainers who wish to widen pre-service teachers’ conceptions of engagement and increase their repertoire of teaching behaviours.  相似文献

OBJECTIVE: This study examined specific aspects of child sexual abuse in relation to symptom severity among hospitalized patients diagnosed with bulimia nervosa. METHOD: Participants were 45 hospitalized bulimic women who reported a history of child sexual abuse. Structured interviews were conducted in order to obtain detailed information regarding specific features of the abusive event(s). Participants also completed instruments that measured depression and eating pathology. RESULTS: There were no significant differences in severity of depression or eating disturbance among women reporting differing abusive experiences including intrafamilial versus extrafamilial abuse, abuse with or without the use of physical force, one versus multiple incidents, early abuse versus abuse occurring after age 14, contact versus noncontact abuse, disclosed versus undisclosed, and combined physical/sexual abuse versus sexual abuse alone. CONCLUSION: The specific characteristics of child sexual abuse are not related to the level of symptomatology for hospitalized bulimic patients. This study suggests that differences in the nature of the abuse may not be as important as the fact that the abuse occurred in the first place.  相似文献
