A comparison of electronic and paper-based assignment submission and feedback

This paper presents the results of a study evaluating student perceptions of online assignment submission. 47 students submitted assignments and received feedback via features within the Virtual Learning Environment Blackboard™. The students then completed questionnaires comparing their experience of online submission and feedback with traditional methods.
Results indicated that 88% of students reported a time saving and many reported financial benefits using online submission. 93% of students preferred having their feedback available online rather than printed and handed to them. Overall, students preferred online assignment management to postal or physical hand-in. The main disadvantage of electronic submission appeared to be student distrust of the receipt system.
The use of online assignment submission and management is recommended for use in Higher Education establishments where students may be remote. It is most suitable for assignments that do not require inclusion of many images.     

Self-regulated strategy development in writing: Going beyond NLEs to a more balanced approach

In this article, we present an argument for consideration by those researching and promoting new learning environments (NLEs). We believe advocates of NLEs should consider the literature and research base indicating effective instruction is not based on a forced dichotomy between theoretical perspectives, but rather a thoughtful, pragmatic blending of practices based on evidence gained from various perspectives and lines of research. While unguided or minimally guided instructional approaches are popular and intuitively appealing, these approaches ignore substantial evidence indicating these approaches are less effective and less efficient than instructional approaches that incorporate guidance of the learning process that is faded as internal guidance is developed (Kirschner et al., Educ Psychol 41:75–86, 2006). We illustrate how integrating evidence from multiple theoretical perspectives leads to the development of more powerful approaches to learning and instruction through a review of the premises, evolution, and research behind Self-Regulated Strategy Development (SRSD) in the area of writing.     

酷玩乐团：年底再会

Grace刚对摇滚乐产生兴趣的时候,酷玩乐团横空出世,所以他们一直在Grace的心目中占据着特殊的位置。不知不觉,明年酷玩即将迎来第一个十年。虽然现在不再像以前那般狂热,但每次他们出专辑还是会很关注——谁能忽视酷玩的影响力呢?所以听说他们将在12月出EP、明年出新专辑的时候,Grace还是兴奋了好一阵子。出碟速度之快,和之前酝酿了三年之久的《生命万岁》差太远了。不过,不管内容如何,作为粉丝的你,一定不会错过吧。     

Early Constraints on the Imagination: The Realism of Young Children

The imagination of young children has notable constraints. The outcomes and possibilities that they imagine rarely deviate from the everyday regularities they have observed and remembered. Their reality-based imagination is evident in a variety of contexts: early pretend play, envisioning the future, judgments about what is possible, the instructive role of thought experiments, tool making, and figurative drawing. Overall, the evidence shows that children’s imagination helps them to anticipate reality and its close alternatives. This perspective invites future research on the scope of children's thinking about counterfactual possibilities, their ability to make discoveries about reality on the basis of thought experiments, and the ways in which cultural input can expand the scope of the possibilities that they entertain.

General population norms about child abuse and neglect and associations with childhood experiences

BACKGROUND: A variety of definitions of child abuse and neglect exist. However, little is known about norms in the general population as to what constitutes child abuse and neglect or how perceived norms may be related to personal experiences. METHODS: We conducted a random-digit-dialed telephone survey of 504 Washington State adults. Respondents were asked whether they believed each of 34 behaviors, identified in focus groups as possibly physically, sexually or emotionally abusive or neglectful, constituted abuse or neglect. Then, they were asked whether they had experienced 33 of the behaviors. RESULTS: Five of the six behaviors with the highest levels of consensus were for sexual abuse, whereas only one emotionally abusive behavior had a high level of consensus (95% agreement). Consensus that spanking constituted abuse increased with severity. Those respondents who reported experiencing a particular behavior were significantly less likely to believe the behavior abusive for 11 of the 33 behaviors and more likely to believe the behavior abusive for two of the behaviors. Where comparisons were possible, there was a high level of consensus that behaviors identified as abusive in Child Protective Service operational definitions constituted abuse. CONCLUSIONS: Self-reported childhood experiences were associated with perceived norms about child abuse. A better understanding of community norms about child abuse and neglect may be helpful in communicating with the public or allow for better targeting of educational messages through the media, parenting education classes, and so forth.
