This study examined whether sixth graders' (mean age = 11.86 years) adjustment to the school context (assessed by grades, achievement scores, and disruptive behavior) was affected by factors from both the family context (represented by students' reports of the number of parenting transitions experienced as well as current levels of supervision, acceptance, autonomy granting, and conflict in the family) and the peer context (represented by students' perceptions of peer norms supporting academic excellence). School adjustment was related to the number of parenting transitions experienced, family climate, and peer norms as well as to higher-order relations involving family climate and peer norms such that ( a ) high grade point averages occurred at only moderate levels of family supervision, ( b ) achievement scores were positively related to supervision at only low levels of family autonomy granting, and ( c ) grade point average was positively related to peer norms at only high levels of family acceptance.  相似文献

To examine how well biology majors have achieved the necessary foundation in evolution, numerous studies have examined how students learn natural selection. However, no studies to date have examined how students learn developmental aspects of evolution (evo-devo). Although evo-devo plays an increasing role in undergraduate biology curricula, we find that instruction often addresses development cursorily, with most of the treatment embedded within instruction on evolution. Based on results of surveys and interviews with students, we suggest that teaching core concepts (CCs) within a framework that integrates supporting concepts (SCs) from both evolutionary and developmental biology can improve evo-devo instruction. We articulate CCs, SCs, and foundational concepts (FCs) that provide an integrative framework to help students master evo-devo concepts and to help educators address specific conceptual difficulties their students have with evo-devo. We then identify the difficulties that undergraduates have with these concepts. Most of these difficulties are of two types: those that are ubiquitous among students in all areas of biology and those that stem from an inadequate understanding of FCs from developmental, cell, and molecular biology.  相似文献

The purpose of the study was to explore a conceptual structure of graduate teaching assistant (GTA) teaching concerns. Results indicated that GTAs experience five distinct, inter-related types of concerns: class control, external evaluation, task, impact and role/time/communication. These ‘teaching concerns’ were further analysed by examining their relationship with the value placed on them by the GTAs and the confidence in dealing with the teaching-related issues of concern. The results revealed that GTAs tend to have concerns about self, task or role/time/communication-related issues when the nature of the concerned issues is perceived as being valuable but challenging. On the other hand, GTAs are more likely to have concerns with impact-related issues when the nature of the issues is perceived as both being valuable and manageable. Several GTA characteristics, such as teaching experience, teacher efficacy, participation in professional development and values on teaching practices, were examined as predictors of GTA teaching concerns.  相似文献

Teachers have only recently considered how study skills support in higher education (HE) can be delivered in a way that encourages experiential learning. This paper aims to substantiate, or otherwise, the idea that a carefully developed initiative can encourage the experiential learning of study skills. In addition, it considers whether such an approach might also allow student access to some of the higher-level study skills required for successful university study. Focus group data were used to evaluate a module delivered to sports students at a post-1992 university in the UK. This data suggested that the module facilitated learning in each stage of Kolb's experiential learning cycle. Moreover, there was evidence that the module encouraged students to undertake an ‘epistemological shift’ in which they moved from seeing knowledge as a set of uncontested facts to seeing it as something that they are expected to question and contribute to themselves.  相似文献

During the 1990s the Teacher Training Agency showed its commitment to adopting elements of a 'competence' model of educational management training in the construction of the National Standards for Headteachers (TTA 1997, 1998). These same 'standards' have come to underpin the most ambitious programme of educational management training and development ever attempted in the UK (Glatter 1997) including the National Professional Qualification for Headship (NPQH), the Headteachers' Leadership and Management Programme (HEADLAMP) and the Leadership Programme for Serving Headteachers (LPSH). This article attempts to trace the origins of competence-based approaches to management training and suggests that the model, though having much to commend it, contains within it a variety of underlying and unresolved tensions.  相似文献

The study provides an analysis of those scholars who produced a substantial number of articles in 24 communication journals during the period, 1996‐2001. The purpose of the study was to update the information provided in previous studies. Using data similar to that previously found in the Index to Journals in Communication Studies, the authors found that during the period a number of new names has appeared. As a result, the authors develop a list of the top one percent (50) of those researchers, as well as providing data on the institutions which these scholars represent. The minimum number of articles necessary during the period to be included was nine.  相似文献

This study examined the effects of office aesthetic quality on students' perceptions of teacher credibility and communicator style. Ninety‐seven individuals from introductory communication courses participated in this experiment. Participants were assigned to visit either a low or a high aesthetic quality office, or to a no‐office exposure control group, prior to evaluating a videotaped sample of an instructor lecturing in a basic communication course. Results indicated that office aesthetic quality influenced participants' evaluations of teacher credibility and communicator style.  相似文献
