The Microelectronics WebLab at MIT allows students to do actual (not simulated) laboratory research on state-of-the art equipment
through the Internet. This study assesses the use of WebLab in a junior-level course on microelectronic devices and circuits
in 2004–05 and 2005–06. In quantitative surveys and qualitative interviews, students and faculty reported that WebLab was
effective as an instrument of learning, and grew more so with refinements of the program. WebLab allowed undergraduates to
learn at their own pace and on their own schedules. It enabled them to use different processes of learning (intuitive, visual,
abstract), and it gave them an opportunity to link individual and collaborative effort in creative combinations. Online laboratories
on this model have broad applications in the experimental sciences and in other research-oriented disciplines. 相似文献

ABSTRACTInternational fieldschools to developing countries have become an important component of the university curriculum because they provide experiential learning and research skills, while also contributing a range of soft skills such as resilience, empathy, resourcefulness, critical thinking, and cross-cultural communication. Yet, with the increasing popularity of ‘developing world’ fieldschools, an ever-more pertinent question to ask is, cui bono? Who benefits when relatively ‘privileged’ students from wealthy countries travel to visit ‘underprivileged’ communities in poorer parts of the world? In this article, we contribute to the discussion about fieldschool reciprocity using data from a newly established program in Northern Uganda, established as part of the University of New South Wales’ UNSW2025 strategy. We show that a whole-of-university approach has significant benefits for staff and students from both institutions, more diffuse benefits for the wider Ugandan host community, as well as the potential to create synergies to leverage community transformation. We also look at challenges that include: power differentials, uncertainty in the field environment, sustainability, and the ability to maintain collaborative equity between institutions over the long term. 相似文献

The present study examined the relationship of child maltreatment to both emotion dysregulation and subsequent eating pathology. In an effort to extend previous research, the authors examined the unique impact of childhood emotional abuse (CEA) on emotion dysregulation and eating disorder (ED) symptoms while controlling for the effects of sexual and physical abuse. Structural equation modeling was utilized to simultaneously examine the effects of all three abuse types on multiple dependent variables as well as examine whether deficits in emotion regulation mediated the relationship between abuse and eating pathology. Results from a survey of 1,254 female college students revealed significant paths from abuse subtypes to specific eating disorder symptoms, with CEA evidencing the strongest association with ED symptoms. Additionally, emotion dysregulation was positively associated with ED symptoms, and mediated the effects of emotional abuse on symptoms. Findings support previous research on the enduring effects of emotional abuse as well as highlight the importance of the assessment of CEA in the treatment of ED symptoms. 相似文献

Advances in cognitive science and educational research indicate that a significant part of spatial cognition is facilitated by gesture (e.g. giving directions, or describing objects or landscape features). We aligned the analysis of gestures with conceptual metaphor theory to probe the use of mental image schemas as a source of concept representations for students' learning of sedimentary processes. A hermeneutical approach enabled us to access student meaning-making from students' verbal reports and gestures about four core geological ideas that involve sea-level change and sediment deposition. The study included 25 students from three US universities. Participants were enrolled in upper-level undergraduate courses on sedimentology and stratigraphy. We used semi-structured interviews for data collection. Our gesture coding focused on three types of gestures: deictic, iconic, and metaphoric. From analysis of video recorded interviews, we interpreted image schemas in gestures and verbal reports. Results suggested that students attempted to make more iconic and metaphoric gestures when dealing with abstract concepts, such as relative sea level, base level, and unconformities. Based on the analysis of gestures that recreated certain patterns including time, strata, and sea-level fluctuations, we reasoned that proper representational gestures may indicate completeness in conceptual understanding. We concluded that students rely on image schemas to develop ideas about complex sedimentary systems. Our research also supports the hypothesis that gestures provide an independent and non-linguistic indicator of image schemas that shape conceptual development, and also play a role in the construction and communication of complex spatial and temporal concepts in the geosciences. 相似文献
