Minimal research papers have investigated the use of student evaluations on the laboratory, a learning medium usually run by teaching assistants with little control of the content, delivery and equipment. Finding the right mix of teaching assistants for the laboratory can be an onerous task due to the many skills required including theoretical and practical know-how, troubleshooting, safety and class management. Using larger classes with multiple teaching assistants, a team-based teaching (TBT) format may be advantageous. A rigorous three-year study across twenty-five courses over repetitive laboratory classes is analysed using a multi-level statistical model considering students, laboratory classes and courses. The study is used to investigate the effectiveness of the TBT format, and quantify the influence each demonstrator has on the laboratory experience. The study found that TBT is effective and the lead demonstrator most influential, influencing up to 55% of the laboratory experience evaluation. 相似文献

A common phenomenon in online discussion groups is the individual who baits and provokes other group members, often with the result of drawing them into fruitless argument and diverting attention from the stated purposes of the group. This study documents a case in which the members of an online community--a feminist web-based discussion forum--are targeted by a "troll" attempting to disrupt their discussion space. We analyze the strategies that make the troller successful and the targeted group largely ineffectual in responding to his attack, as a means to understand how such behavior might be minimized and managed in general. The analysis further suggests that feminist and other nonmainstream online forums are especially vulnerable, in that they must balance inclusive ideals against the need for protection and safety, a tension that can be exploited by disruptive elements to generate intragroup conflict. 相似文献

Children with emotional and behavioural difficulties (EBD) and those who also have developmental disorders, such as attention deficit hyperactivity disorder (ADHD) or autism spectrum disorder (ASD), can experience the same adverse consequences in their peer interactions and relationships. This present study compared the emotion regulation and peer relationships of children aged 8–12 years (M = 9.86 years, SD = 1.49) with EBD (N = 33) and children with EBD plus a diagnosed developmental disorder (N = 28). Multivariate analysis of variance (MANOVA) with Bonferroni adjusted alpha levels revealed no significant main effect for emotion regulation according to EBD status. There was, however, a multivariate main effect for sex, with females presenting with higher levels of negative emotional intensity (e.g., frustration, anger, aggression) than males. A second MANOVA revealed no significant main effect for peer relationships according to EBD status and sex. Significant correlations revealed that the EBD-only group experienced greater adverse peer interactions than the EBD-plus-developmental disorder group. These findings are important for educators and researchers involved in the development and evaluation of prevention and intervention programms for children with EBD. 相似文献

This article explores variations in mental health and service utilization across academic disciplines using a random sample of undergraduate and graduate students (N = 64,519) at 81 colleges and universities. We report prevalence of depression, anxiety, suicidality, and self-injury, and rates of help-seeking across disciplines, including results from multivariate logistic regressions. We find significant variations: Students in humanities and art and design are significantly more likely to have mental health problems; and for students with apparent mental health problems, treatment rates are lowest among those in business and engineering. Noting these variations could enhance efforts to promote student mental health, particularly within academic departments. 相似文献

In this paper we describe our research using a multi-user virtual environment, Quest Atlantis, to embed fourth grade students in an aquatic habitat simulation. Specifically targeted towards engaging students in a rich
inquiry investigation, we layered a socio-scientific narrative and an interactive rule set into a multi-user virtual environment
gaming engine to establish a virtual world through which students learned about science inquiry, water quality concepts, and
the challenges in balancing scientific and socio-economic factors. Overall, students were clearly engaged, participated in
rich scientific discourse, submitted quality work, and learned science content. Further, through participation in this narrative,
students developed a rich perceptual, conceptual, and ethical understanding of science. This study suggests that multi-user
virtual worlds can be effectively leveraged to support academic content learning. 相似文献
