An assessment of student satisfaction with peer teaching of clinical communication skills
Background: Peer teaching is now used in medical education with its value increasingly being recognised. It is
not yet established whether students differ in their satisfaction with teaching by peer-teachers compared to those
taught by academic or clinical staff. This study aimed to establish satisfaction with communication skills teaching
between these three teaching groups.
Methods: Students participated in a role-play practical facilitated either by clinicians, peer-teachers or non-clinical
staff. A questionnaire was administered to first-year medical students after participating in a communication skills
role-play session asking students to evaluate their satisfaction with the session. Data were analysed in SPSS 20.
Results: One hundred and ninety eight students out of 239 (83%) responded. Students were highly satisfied with
the teaching session with no difference in satisfaction scores found between those sessions taught by peers, clinical
and non-clinical staff members. 158 (80%) considered the session useful and 139 (69%) strongly agreed tutors facilitated
their development. There was no significant difference in satisfaction scores based on tutor background.
Conclusions: Satisfaction is as high when tutored by peer-teachers compared to clinicians or non-clinical staff.
Constructive feedback is welcomed from a range of personnel. Final-year students could play an increasing role in the
teaching of pre-clinical medical students
A framework for design engineering education in a global context
This paper presents a framework for teaching design engineering in a global context using innovative technologies to enable distributed teams to work together effectively across international and cultural boundaries. The DIDET Framework represents the findings of a 5-year project conducted by the University of Strathclyde, Stanford University and Olin College which enhanced student learning opportunities by enabling them to partake in global, team based design engineering projects, directly experiencing different cultural contexts and accessing a variety of digital information sources via a range of innovative technology. The use of innovative technology enabled the formalization of design knowledge within international student teams as did the methods that were developed for students to store, share and reuse information. Coaching methods were used by teaching staff to support distributed teams and evaluation work on relevant classes was carried out regularly to allow ongoing improvement of learning and teaching and show improvements in student learning. Major findings of the 5 year project include the requirement to overcome technological, pedagogical and cultural issues for successful eLearning implementations. The DIDET Framework encapsulates all the conclusions relating to design engineering in a global context. Each of the principles for effective distributed design learning is shown along with relevant findings and suggested metrics. The findings detailed in the paper were reached through a series of interventions in design engineering education at the collaborating institutions. Evaluation was carried out on an ongoing basis and fed back into project development, both on the pedagogical and the technological approaches
Carryover Effect of New Soybean Herbicides on Corn
Scepter, Canopy, Gemini, Classic, and Command are new soybean herbicides which were introduced in 1986 and are being used in Kentucky. These herbicides have gained widespread popularity because of their excellent control of cocklebur, pigweeds, morningglories, and velvetleaf. In addition, they can be applied in a variety of ways which makes them attractive to the soybean producer. However, these herbicides do have potential shortcomings in that they can persist in the soil for several months and cause injury to rotational crops such as corn or wheat. Since greater than 60% of the soybeans grown in Kentucky are rotated to corn, it is important to know the persistence potential of these newer soybean herbicides. Chlorimuron is one of the active ingredients in Canopy, Preview, Gemini, Lorox Plus, and Classic. We have conducted research with chlorimuron at rates comparable to those recommended for Canopy and Gemini. Research on the persistence of Scepter, Command, and Canopy was started in 1985. After having been applied to the soil and soybeans grown, corn was planted the following year, and the degree of corn injury monitored. The persistence of Scepter and Command was determined in three tillage systems: conventional moldboard plowing and disking; full-season no-tillage in which a wheat cover crop was killed with Gramoxone Super 10 days prior to planting; double-crop no-tillage in which soybeans were planted after wheat harvest. Canopy persistence was determined in conventionally tilled soils that had a pH of 5.3, 6.3, or 7.3. All herbicides were applied at their labeled rate and at 1.5 and 2 times the labeled rate
Cybergriping: Violating the Law while E-Complaining
The emergence of Web communications has given rise to complaint sites which serve as central forums for both consumers and employees to share their bad experiences. These complaint sites provide for cybergriping in various forms. This paper explores the concept of cybergriping and its relevance to the hospitality and tourism industry from employee and customer perspectives. Court cases in which cybergriping played a key role are reviewed, and recommendations are offered on how hospitality and tourism businesses can address the problem of cybergriping
Stochastic oscillations of adaptive networks: application to epidemic modelling
Adaptive-network models are typically studied using deterministic
differential equations which approximately describe their dynamics. In
simulations, however, the discrete nature of the network gives rise to
intrinsic noise which can radically alter the system's behaviour. In this
article we develop a method to predict the effects of stochasticity in adaptive
networks by making use of a pair-based proxy model. The technique is developed
in the context of an epidemiological model of a disease spreading over an
adaptive network of infectious contact. Our analysis reveals that in this model
the structure of the network exhibits stochastic oscillations in response to
fluctuations in the disease dynamic.Comment: 11 pages, 4 figure
Developing and Managing I-O Online: What’s Behind the Virtual Classroom?
In recent years there has been an increase in the number of courses and degree programs offered online. This is particularly true in the field of industrial and organizational psychology, wherein many students are working professionals who, while unable to leave their jobs, are seeking convenient ways to supplement their experience with the necessary education. Despite this surge in student interest, many educators lack explicit training in making the transition to online education. Here, a variety of individuals experienced in various aspects of developing online I-O degree programs—both undergraduate and graduate—discuss best practices for such a program as well as discuss its pedagogical challenges. In attempts to guide other institutions developing similar programs in the future, these individuals discuss what has (and has not) worked as they have supplemented their institutions’ traditional on-campus I-O programs with online equivalents
