The present study examined the pattern of association(s) over time between (a) knowledge of and observational skills in identifying teacher–child interactions, and (b) observed behavior in the domain of instructional interaction for 405 preschool teachers enrolled in a professional development study. Teacher's knowledge/observational skills and observed instructional support behaviors with children were assessed in the fall and spring over a two-year period. During this time, the teachers were also randomized into a college course focused on interactions, then re-randomized into a coaching intervention, also focused on instructional interaction. Cross-lagged analyses suggest that prior observed behavior was the stronger predictor of change in both knowledge/observation skills and in later observed behavior, and that both the course and the coaching interventions contributed to improvements in teachers observed instructional support behavior. Mediational analyses of the course effects indicated longer-term impact on observed instructional behavior were through immediate impacts on those same behaviors, whereas long-term impacts on knowledge were through immediate impacts on both observed instructional behavior and knowledge. The results have implications for the design, delivery, and focus of professional development for early childhood educators. 相似文献

Scholars have assessed the degree to which heterosexual men and women make differential judgments of flirtatiousness, seductiveness, and promiscuousness during cross-sex interactions. Findings from extant research suggest that men decode verbal and nonverbal communication cues differently than do women, and this difference results in men's tendency to rate individuals more highly in levels of these social–sexual constructs than do women. This paper reports the results of three meta-analyses that provided estimates of the magnitude of the sex differences in perceptions of flirtatiousness, seductiveness, and promiscuousness and argues that these results are consistent with error management theory. Sex of target and mode of observation interacted to impact observed sex differences. Sex differences were strongest for female targets when research participants were observers of face-to-face interactions (average r=.32), whereas sex differences in evaluations of flirtatiousness, seductiveness, and promiscuousness were strongest for participants who were rating male targets in face-to-face interactions (average r=.36). The implications of these results are discussed. 相似文献

This paper explores the effect of mothers' child abuse potential on maternal and child behaviors during play‐time interactions. Forty‐two mothers participated in a 10‐min play period followed by a clean‐up task along with one of their children (range=3–8 years old), after which they completed Milner's () Child Abuse Potential (CAP) Inventory. Mothers' behaviors were coded using a 21‐category scheme, which was collapsed into five behavioral clusters: describing, directing, criticizing, soliciting/affirming, and silent play. Children were rated for levels of involvement (activity) and cooperation. Mothers' child abuse potential scores were inversely associated with their own rate of soliciting/affirming behaviors during the play period. Children of higher‐risk mothers displayed higher levels of involvement combined with lower levels of cooperation compared children of lower‐risk mothers. Implications for understanding and responding to child physical abuse are discussed. 相似文献

This study investigated the effects of collaboration mode and group composition during a computer-mediated collaborative (CMC)
program. Six intact sections of a computer literacy course were assigned to either a face-to-face or a virtual, online collaboration
treatment condition. Groups consisted of homogeneous lower-ability, homogeneous higher-ability, or heterogeneous-ability pairs.
The study examined the effects of collaboration mode and group composition on individual posttest performance, group project
performance, collaborative interaction behavior, and attitudes towards the instruction. Results indicated that virtual dyads
exhibited significantly more questioning behaviors and significantly better project performance than those who collaborated
face-to-face. By comparison, students in the face-to-face condition performed significantly better on the individual posttest
than those in the virtual online condition. Findings suggest that both virtual and face-to-face collaboration can be effective
in achieving learning goals. However, consideration should be given to the collaborative structure of the lesson and the type
of task in the design of CMC environments.

Increasing teacher verbal approval has been shown to produce both increased pupil “on-task” behaviour and academic achievement. The present study aimed to address gaps in current knowledge about the effect of different kinds of teacher approval, other than verbal approval, on students’ performance. An exploratory study, followed by an experimental study, was conducted with Italian undergraduate psychology students in order to investigate the effect of written approval on their academic performance. The results indicate that, whilst there is some suggestion that students appreciated receiving increased written approval comments on their work, the receipt of such comments was accompanied by poorer academic performance than that of a control group. Possible explanations are presented. 相似文献

This research examined the ways in which academic librarians and users interact when using social media tools such as Twitter and Weibo as well as end-users' and librarians' perceptions of the types of interaction through social media. The study conducted an analysis of 1600 microblog posts sampled from twenty university library Weibo (Chinese Twitter) sites and twenty library Twitter sites in English-speaking countries. The results were compared using Chi-Square analysis. Results indicated that at present academic librarians in English-speaking countries use post information relevant to the library (news and events) and respond to information/research inquiries. And academic librarians in China are likely to use Weibo to communicate with users and to disseminate library news. Given the lack of previous research on how social media such as micro-blogging in general facilitates communication between librarians and library users in academic libraries between in English-speaking countries and China, this study provides valuable information concerning librarians' and end-users' interactions of information/knowledge sharing activities, which will enable libraries to be better positioned to promote user engagement through SNS usage. 相似文献

流域宏观尺度降雨-景观-径流变化的相互作用 总被引：1，自引：0，他引：1
大流域宏观尺度上长时间序列的降雨变化、景观变化、径流变化及其相互作用是近年来研究全球变化的一个重要问题。本文研究泾河流域降雨-景观-径流变化的相互作用，结果表明：①泾河流域中上游主流域40多年来的降水具有微弱下降趋势，降雨倾向率为-4.9mm/10～-11.3mm/10年；泾河流域马莲河分流域，年降雨量表现为不变或微弱下降；②泾河流域1986年～2000年15年之间，景观结构变化不大，一直以草地景观和耕地景观为主。草地景观和农耕地景观二者始终占流域总面积的85%以上，林地景观始终占流域总面积的10%左右，其他景观类型一直占流域总面积的5%左右。在宏观景观格局的变化中，泾河流域中上游主流域，农耕地景观所占比例有所上升，而泾河流域马莲河分流域农耕地景观所占比例维持稳定；③泾河流域中上游主流域年径流量逐年较大幅度地减少，下降速度达到每10年减少1.78m3/s。在泾河流域马莲河分流域，年径流和径流模数在过去30年中基本维持稳定，整个泾河流域年径流量逐年下降；④相应年份内对应的径流和降雨相关性极为显著（P<0.01）。在泾河主流域中上游地区降水每减少10mm，径流可能相应减少70×108m3，在马莲河分流域地区每减少10mm，径流可能减少110×108m3。在泾河流域，若维持景观结构的稳定，则径流的变化趋势会与降雨的变化趋势保持一致。景观结构的微弱变化会改变径流对降雨响应的变化幅度。在景观组成中，耕地景观比例的增加会显著减少径流。 相似文献

独立学院学生的口语僵化现象令人担忧。除了语言因素的影响之外,语言心理机制和情感因素是造成口语能力裹足不前的主要原因。在独立学院英语课堂上运用"三动"教学模式即"生生互动、师生互动、内外互动"的教学模式能有效地解决这一问题。实证研究证明"三动"教学模式对于激活独立学院学生的口语僵化具有明显的作用。 相似文献

Despite the persistence of sex‐typed images of the expressivity of wife and husband, past observational studies have given little indication of sex‐linked differences in marital communication. Thus, we proposed that inter personally negotiated role expectations would be a better predictor of communication about marital conflict than sex. However, we also proposed that there might be sex differences within particular clusters of couples who endorse sex‐differentiated role expectations. Couples were classified into groups using Fitzpatrick's (1983) typology. The results of two studies indicated that couple type was significantly related to communication about marital conflict; however, there were neither any clear overall sex differences in communication nor sex differences within couple types. Rather, the results indicated that conflict styles are so strongly reciprocal that mutual influence within conversations tends to remove individual speaker differences. The research suggests that mutual influence processes and mutually established beliefs and expectations account for conflict styles more adequately than biological sex. 相似文献
