How confident are college faculty to integrate technology in their teaching? This study examined relationships between faculty computer self-efficacy and integration of electronic communication when teaching. Faculty at a Research I land-grant university were mailed a self-report questionnaire yielding a 59 percent response rate. Over half used electronic communication in their courses, mostly for course-related announcements and deadlines, but least for synchronous communication. Computer self-efficacy scores differed on age, gender, college, integration, and computer experience. Low integrators and female faculty reported lower confidence in using computers. As universities offer courses with significant Web-presence, faculty development efforts need to increase self-efficacy by providing hands-on experiences in technologically supported environments.  相似文献

The main premise of this article is that in information societies generally, and in virtual social contexts particularly, a distinctive style of interaction to facilitate the communication of difference, heterotopic communication , has emerged. It rests on two cultural foundations: an ideological belief in the positive, socially integrating power of communication, and a prevailing ethic of instrumental rationality, subjective individualism, and strategically practiced self-interest. The former is demonstrated by the use of simulation and spectacle as sources of information; exhibitionism/voyeurism as a communicative style; and the awareness of surveillance. The latter is seen in the competitive use of knowledge as a commodity; a surface globalism masking deep parochialism; lateral as well as vertical information inequity; and the use of public versus private as strategies for engagement rather than as spaces. Those who engage in heterotopic communication resort to their 'own devices' both in the sense of personal agendas, strategies, interests, and interpretations, and in the form of the telecommunication tools that help realize them. These personal and technological devices allow individuals with the right educational and technical resources to avoid exposure to disagreement, difference, or other information that does not serve their direct purposes or reflect their particular views of the world; yet they also help convey the appearance of openness, availability, and cooperation. This style of interaction is used strategically in combination with information and communication technologies to gain social or economic advantages, but it may encourage social separatism and parochialism, inhibit the negotiation of disputes, and emphasize competing interests.  相似文献

Employing an experimental design, mother-to-infant transmission of stress was examined. Mothers (N = 117) were randomized to either have a positive or conflictual discussion with their marital partners, after which infants (age = 6 months) participated in a fear and frustration task. Saliva samples were collected to assess maternal cortisol responses to the discussion and infant cortisol responses to the challenge task. Results indicate maternal cortisol reactivity and recovery to the conflict (but not positive) discussion predicted infant cortisol reactivity to the infant challenge. Mothers’ positive affect during the discussion buffered, and intrusion during the free-play potentiated, mother-to-infant adrenocortical transmission. These findings advance our understanding of the social and contextual regulation of adrenocortical activity in early childhood.  相似文献

OBJECTIVE: The purpose of this paper is to present a newly developed measure of guardian support, the Needs-Based Assessment of Parental (Guardian) Support (NAPS), an empirical evaluation of that measure, and its comparison with another measure of guardian support. The theoretical model that underlies this measure applies humanistic theory and Maslow's hierarchy of needs to the understanding of guardian support. METHOD: The study employed a cross-sectional nonexperimental survey design using 183 nonoffending guardians who accompanied children presenting for a medical/forensic examination for sexual abuse. The NAPS and an existing measure of guardian support were administered during the hospital outpatient visit, and basic information concerning the child and abuse situations were gathered. RESULTS: The NAPS had robust psychometric properties and was culturally sensitive. Tests of specific hypotheses supported the construct validity of the measure and a conceptualization of guardian support as hierarchical, with four stages of support. CONCLUSIONS: The brevity and ease of administration of the NAPS for both the clinician and guardian suggest that it is a viable assessment tool. The strong support for the NAPS' underlying theoretical model suggests that the nonoffending guardians' available resources need to be considered when assessing guardian support.  相似文献

北美地区区域十分辽阔,有着多种化和种族群体。无论在现代化的美国本土,还是在寒冷的阿拉斯加和加拿大,或是在荒漠、炎热和潮湿的北美区域,都有我们早期教育的课堂。早期教育渗透在拥挤的都市,同时也深入到了偏远条件艰苦的地方。北美地区的幼儿教育,是差别很大的概念。  相似文献

The purpose of this study was to identify the specific types of verbally aggressive messages emerging adult siblings use with each other and to determine whether these types of verbally aggressive messages differ in perceived hurtfulness, intensity, and intent. Participants were 115 individuals who identified a verbally aggressive message recently used by a sibling. Results indicated that siblings use seven types of verbally aggressive messages (i.e., name calling, insults, withdrawal, physical acts or threats, repudiating the relationship, negative affect, unfair comparison), and the seven types of verbally aggressive messages do not differ in their perceived hurtfulness, intensity, and intent.  相似文献

Research in organizational communication and public relations suggest that in times of crises, messages generated by the organization are most likely to positively influence stakeholder perceptions, whereas those generated by the press may have negative ramifications. Although this advice seems logical, to date there is little research that investigates this claim empirically and directly. Two experiments were conducted to explore the separate and combined impact of print and televised messages concerning an organization in the midst of a crisis. The findings offer empirical evidence that statements from organizations experiencing crises may offset negative stakeholder responses. Theoretical and pragmatic implications are discussed regarding these findings.  相似文献
