This experimental study examines an online module designed to increase student competence in oral citation behavior using a mastery training strategy. Students in the experimental condition provided complete citations at a higher rate and provided more citation information for traditional and web-based sources compared with a control group without required training. Although subjective norms set by instructors also influence citation behavior, the general trend depicted was that students completing the required module training performed more complete citations. Implications for student learning, mastery instruction, and course assessment were considered to be generally beneficial and at minimal cost.  相似文献

ABSTRACT

Press credentialing practices are a vital, yet understudied site of scholarly research on journalistic norms and practices. Press credentialing not only structures internal professional hierarchies, but they also signify the boundaries of the journalistic field itself. This paper explores the legal and theoretical implications of press credentialing to cover the United States Congress, drawing on the concepts of boundary work and journalistic authority to demonstrate the material impact of the space between fields on professional legitimation in journalism. Using WorldNetDaily (WND) as a case study, I argue that the Standing Committee of Correspondents (SCC) occupies a hybrid boundary zone between the journalistic and political fields, generating a unique tension in First Amendment jurisprudence that places journalists in a paradoxical role as both the professional embodiments of free speech and its constitutional steward. The resulting jurisdictional conflict between the SCC and WND extends the relational model of journalistic authority by articulating how journalist-state relations can fundamentally augment the process of legitimation at its fuzzy boundaries. The relevance and implications for press credentialing practices in the digital age are discussed.  相似文献

This article describes a three‐year project undertaken at Pear Tree School for children and young people with severe and multiple and profound learning difficulties. Lesley Sullivan, the school's head teacher, believed that much of the value within the work of this outstanding school went unidentified by existing approaches to planning, monitoring and evaluation. Richard Crombie, educational psychologist, was engaged to work on the project. Also involved were Kate Walker and Rebecca Warnock, deputy head teachers, as well as the whole staff, children and some parents. The project takes as its starting point that essential, but very often unnoticed and unconscious, professional practice is rooted in implicit processes learnt experientially. We set ourselves the task of finding meaningful frameworks for identifying and developing that practice. This meant close observation within and outside school coupled with feeding back to staff, and their subsequent engagement with and use of explanatory frameworks.  相似文献

Emerging fathers experience a variety of stressors, including identity and role transitions, changes in their relationships, and challenges in developing caregiving skills. Increasing expectations for father involvement in childcare are emphasizing the importance of the father role, but social supports for new fathers remain scarce. Nineteen expectant and new fathers participated in a pilot 5-week group intervention aimed at improving stress coping and involvement attitudes using a combination of mindfulness practices and skill-building for parenting and partner communication. We administered surveys pre- and postintervention to assess efficacy in the areas of stress, depressive symptoms, father involvement attitudes, and mindfulness. Within-participant differences were compared across participants as well as examining individual reliable change. Results indicated initial reductions in stress and depressive symptoms and increases in the mindfulness constructs of nonjudgment and nonreactivity. No significant changes were found in father involvement attitudes. Perinatal intervention specific to fathers holds promise as an underexplored avenue for supporting families across the transition to parenthood.  相似文献
