Student comments are routinely collected in university evaluation surveys for the purpose of improving teaching and learning. Whilst student comments provide valuable insights into their experiences, there is limited published research reporting the extent to which student comments are offensive and professional. The aim of this study was to investigate the number of student comments that were identified as being offensive or unprofessional in an online unit evaluation survey collected in a semester in 2010 from an Australian university. One person read 30,684 comments taken from 17,855 surveys and identified comments considered to be abusive or unprofessional. Comments were categorised as either abusive or unprofessional and by the intended target (that is, teacher, unit, resource). Thirteen abusive comments (0.04 % of the sample) were identified. Five abusive comments were directed at the teacher and eight were targeted at teaching and learning experiences. Forty-six comments (0.15 % of the sample) were identified as unprofessional. Of these, seven comments were directed at the teacher and 34 were about units. This suggests that the vast majority of students do not abuse the privilege of giving anonymous feedback. Strategies identified in this paper to educate students and give appropriate feedback can be adopted by universities to minimise offensive comments. Universities can educate students and teachers in appropriate and professional ways of working together, in providing professional feedback to improve the student experience in teaching and learning and to support and mentor teachers in their academic careers. 相似文献

Lecture capture, defined here as the capturing of some or all elements of a live lecture in digital format, is becoming increasingly popular in higher education. Despite this increase in popularity, fewer than 10% of institutes of higher education globally have adopted comprehensive lecture capture systems. So, the majority of instructors wanting to use lecture capture technology will find themselves having to acquire their own technology and do the capture themselves. There are several factors that influence the use of lecture capture, including the instructor’s level of comfort with technology, their budget, and the context in which they will be using the tool. Using case studies of our own experiences, we hope to illustrate a variety of ways in which lecture capture can be appropriately used in higher education in this way. Following this, we outline several challenges that we faced and provide recommendations for how to overcome these. Lastly, we describe some issues that should be considered and addressed before getting started using lecture capture technology in a way that is customized to suit the needs of both professor and student. We hope that by following the guidelines outlined in this paper, and by seeing practical examples of how lecture capture can be used in a variety of contexts, the transition from idea to implementation will be an easier one. 相似文献

Many researchers assessing the efficacy of educational programs face challenges due to issues with non-randomization and the likelihood of dependence between nested subjects. The purpose of the study was to demonstrate a rigorous research methodology using a hierarchical propensity score matching method that can be utilized in contexts where randomization is not feasible and dependence between subjects is a concern. Although propensity score matching is not new in helping to create quasi-experimental models, many studies limit propensity score matching to student-level variables. To address this limitation in educational research, this study extends propensity score matching to the next level so that hierarchical modeling techniques can be used to help minimize error due to the likelihood of dependence between nested students. A large-scale educational program that targets first-semester freshmen was used to illustrate the utility and value of the methodology. This type of program is typical in higher education where student self-selection creates difficulty in assessing its true effects on student achievement; however, by using a rigorous methodology, administrators can have higher confidence when making programmatic and budgetary decisions. 相似文献

Cell culture in microfluidic systems has primarily been conducted in devices comprised of polydimethylsiloxane (PDMS) or other elastomers. As polystyrene (PS) is the most characterized and commonly used substrate material for cell culture, microfluidic cell culture would ideally be conducted in PS-based microsystems that also enable tight control of perfusion and hydrodynamic conditions, which are especially important for culture of vascular cell types. Here, we report a simple method to prototype perfusable PS microfluidics for endothelial cell culture under flow that can be fabricated using standard lithography and wet laboratory equipment to enable stable perfusion at shear stresses up to 300 dyn/cm2 and pumping pressures up to 26 kPa for at least 100 h. This technique can also be extended to fabricate perfusable hybrid PS-PDMS microfluidics of which one application is for increased efficiency of viral transduction in non-adherent suspension cells by leveraging the high surface area to volume ratio of microfluidics and adhesion molecules that are optimized for PS substrates. These biologically compatible microfluidic devices can be made more accessible to biological-based laboratories through the outsourcing of lithography to various available microfluidic foundries. 相似文献

Abstract In this study, we examined the minimum number of constant-torque passive stretches necessary to reduce musculotendinous stiffness. Thirteen healthy individuals (mean age 22 years, s = 3; stature 1.67 m, s = 0.1; mass 66 kg, s = 13 kg) volunteered to participate in the investigation and underwent four 30-s constant-torque passive stretches of the plantar flexor muscles. Musculotendinous stiffness was examined from the angle–torque curves generated prior to the passive stretches, at the beginning of each 30-s stretch, and immediately following the four 30-s passive stretches. The results indicated that musculotendinous stiffness of the plantar flexors was reduced following two 30-s constant-torque passive stretches (P < 0.05) compared with the pre- musculotendinous stiffness assessment. Musculotendinous stiffness remained depressed following the third and fourth stretches, but did not decrease further. These findings suggest that two 30-s bouts of constant-torque passive stretching may be necessary to cause a significant decrease in musculotendinous stiffness of the plantar flexor muscles. 相似文献

Educational-policy makers worldwide are concerned with finding effective strategies to recruit and retain high-quality teachers. The recruitment of second-career teachers has been seen as one means of fulfilling this aim. Against a background of calls to better understand SCTs, this article reports the results of a qualitative study investigating the experiences of six second-career teachers in Hong Kong. Based on a theoretical framework of teacher-identity construction, discourse analysis was used to explore the participants’ perceptions of their professional development. In-depth interviews were conducted to gain detailed insights into how the teachers construct their identities-in-practice and identities-in-discourse within Hong Kong schools. The findings expose tensions between attempts the positioning of SCTs within dominant discourses as ‘traditional’ and ‘conventional’ teachers, for example, and the participants’ self-positioning in practice as ‘innovative’ and ‘risk-taking’ teachers. Ways in SCT agency, and hence identity construction, can be facilitated through the introduction of the innovative pedagogical practices which many SCTs seek to pursue in Hong Kong schools are considered. 相似文献

Background: Participation in youth sport is often associated with a variety of positive development outcomes. In order to effectively utilize sport as a context of learning and development, the sport must be intentionally designed and programed. One often-used approach is known as sport-based positive youth development (PYD). Recently, to further enhance the intentionality of a sport-based PYD approach, several researchers have posited the potential benefits of applying experiential learning theory to youth sport programing. Through utilizing experiential learning within a sport-based PYD approach, it is believed youth sport can be designed to intentionally promote desired PYD outcomes.Purpose: Experiential learning theory offers a deep understanding and history of effective youth programing. However, within the field of experiential learning, many different pedagogical approaches exist. To date, sport-based PYD has yet to identify a specific pedagogical approach within experiential learning. In order to be accessible and applicable for youth sport leaders, a more definitive pedagogical approach is needed. One specific application of experiential learning which offers specific programing techniques that are compatible with a sport-based PYD approach is adventure pedagogy.Conclusions: Adventure pedagogy draws from adventure-based learning and adventure-based groupwork. Thus, adventure pedagogy is defined as a participant-centered approach consisting of intentionally designed and sequenced challenging group activities, which, when processed and debriefed, can lead to a shared opportunity for growth and development related to the intrapersonal development and interpersonal skills. Specifically, to enhance the programing and practices of the youth sport leader, this paper identifies key tenets of adventure pedagogy and highlights their applicability within a sport-based PYD approach. These tenets include the promotion of PYD outcomes, physical and emotional safety, intentionally designed activities, sequencing of prescribed activities, a novel learning experiences, intentional facilitation, challenging group activities, real and immediate consequences, and debriefing to transfer learning. Through the integration of adventure and sport-based PYD, youth sport leaders can effectively program and facilitate youth sport to promote desired PYD outcomes. 相似文献

Many field sports involve equipment that restricts one or both arms from moving while running. Arm swing during running has been examined from a biomechanical and physiologic perspective but not from an injury perspective. Moreover, only bilateral arm swing suppression has been studied with respect to running. The purpose of this study was to determine the influence of running with one arm restrained on lower extremity mechanics associated with running or sport-related injury. Fifteen healthy participants ran at a self-selected speed with typical arm swing, with one arm restrained and with both arms restrained. Lower extremity kinematics and spatiotemporal measures were analysed for all arm swing conditions. Running with one arm restrained resulted in increased frontal plane knee and hip angles, decreased foot strike angle, and decreased centre of mass vertical displacement compared to typical arm swing or bilateral arm swing restriction. Stride length was decreased and step frequency increased when running with one or both arms restrained. Unilateral arm swing restriction induces changes in lower extremity kinematics that are not similar to running with bilateral arm swing restriction or typical arm swing motion. Running with one arm restrained increases frontal plane mechanics associated with risk of knee injury. 相似文献
