Tackling the knowledge explosion without overloading the student

SUMMARY Assessment of today's approach to veterinary education reveals a system overloaded with facts and students stressed to memorise and recall medical information. The Mississippi State University College of Veterinary Medicine has chartered a path to reduce the curricular information overload. The innovative incorporation of computers into the curriculum coupled with problem-based learning activities are preparing students to find information and learn on their own.     

Learning evidence-based veterinary medicine through development of a critically appraised topic

Evidence-based veterinary medicine is a relatively new field of study. Increased knowledge of medicine coupled with the increased ability of computers and other electronic devices present overwhelming information. The critically appraised topic (CAT) is one method to gather and evaluate information related to a clinical question. CATs in informatics are short summaries of evidence, usually found through literature searches, in response to a specifically stated, clinically oriented problem or question. This article describes a study in which each first-year veterinary student developed a CAT as a class project. The results of this project indicate that students were able to successfully develop CATs and that this exercise helped them understand evidence-based veterinary medicine concepts. Though some modification in this project will be made in the future, overall it was a worthwhile effort and will remain as an activity in the course.     

Use of Internet-based resources to support an introductory animal and poultry science course.

This article describes the development and implementation of a World Wide Web page to support a team-taught introductory animal and poultry science course. The objectives were to examine the capabilities of this type of instructional resource, determine students' willingness to use this type of resource, create opportunities for interactive learning, and improve students' enthusiasm for the subject area. A variety of course materials were made available through the Internet, including the class syllabus, lecture notes, and practice questions to support and augment class lectures. Additional on-line resources included a bulletin board for instructor announcements, a list-serve for student discussions concerning administrative and educational issues arising during the semester, a class E-mail list, and a page with links to other sites of agricultural interest. Materials were accessible from a variety of computer resources, including campus computing laboratories, dial-up access, and access via other Internet service providers. Use of the materials was evaluated by analysis of log files from the server. Effectiveness of the resources was determined from surveys of students conducted before and after implementation of the on-line resource. Students indicated that the most useful components of the Web page were the class notes and practice/review questions. Effectiveness of the site was related to the amount of material available through the site, the level of interaction, whether the task was required, and the ease of access to computers and the Web site. Student evaluations indicated that this form of instructional supplement is a viable method for enhancing the learning experience in the introductory animal sciences.     

The role of handouts,note-taking and overhead transparencies in veterinary science lectures

OBJECTIVE: To study student and staff views of the role and use of handouts, note-taking and overhead transparencies in veterinary science lectures at the University of Queensland METHODS: The Nominal Group Technique was used to help develop a questionnaire, which was completed by 351 students (a response rate of 84%) and 35 staff (76%) from the 5 years of the veterinary course. The data were analysed using the SAS statistical computer package. RESULTS: Staff and students held different views as to the frequency with which handouts should be used, their educational value, and whether they should be complete or partial. Fewer students than staff agreed that handouts discourage further reading in a subject. Almost all staff and students saw the central functions of note-taking to be provision of notes for subsequent revision and encoding information given by the lecturer. More students than staff however, considered that note-taking in lectures interferes with understanding. Staff and students held similar views as to the uses of overheads in lectures. Interestingly however, more staff than students agreed that overheads often contain too much information. CONCLUSION: Both students and staff saw the central role of note-taking as providing a set of good notes for revision. Generally students preferred that this information be provided in the form of partial or complete handouts, while staff preferred students to take notes and to read outside lectures. Surprisingly, more staff than students felt that overhead transparencies often contained too much information. Note-taking, handouts and overhead transparencies need to be linked in a coherent educational strategy to promote effective learning.     

Development and evaluation of a high-fidelity canine patient simulator for veterinary clinical training

High-fidelity human patient simulators have been used for decades in medical education to provide opportunities for students to practice technical skills, diagnostic and therapeutic planning, and communication skills in a safe environment. A high-fidelity canine patient simulator (CPS) was developed using components from a human patient simulator and a low-fidelity foam core canine mannequin. Ninety-six veterinary students participated in cardiopulmonary arrest scenarios in groups of three to five students. Afterwards, participants were asked to complete an anonymous online survey describing their experiences. A total of 70 students (73%) completed the survey. All of the students (100%) felt that the simulator session expanded their cardiopulmonary resuscitation (CPR) knowledge base, and 97% responded that their skills and abilities had improved. Students also expressed positive opinions about the CPS, with 89% agreeing or strongly agreeing that the CPS was realistic and 73% agreeing or strongly agreeing that the scenarios generated emotions similar to real clinical situations. Most participants (98.5%) agreed or strongly agreed that the simulator was an engaging learning experience. Students commonly commented that the simulations allowed them to practice communication and teamwork skills and were more effective than paper-based, problem-oriented learning opportunities and lecture. Students also commented that they wanted more opportunities to participate in simulation exercises. These results suggest that high-fidelity veterinary simulation is an engaging educational methodology that addresses some limitations of other forms of problem-based learning. More studies are needed to quantitatively determine the effectiveness of this novel veterinary educational technology in comparison with more traditional approaches.     

Student assessment of the educational benefits of using a CD-ROM for instruction of basic surgical skills

RATIONALE FOR STUDY: At Texas A&M University, introductory-level surgical lecture and laboratory notes were converted to a CD-ROM format that included illustrative photographs as well as instructional videos demonstrating the basic surgical skills that all students were required to master. The CD-ROM was distributed to all students in place of traditional paper notes in the second-year surgical class in the professional veterinary curriculum. The study reported here was designed to evaluate the educational benefits of the use of the CD-ROM in place of traditional paper notes by examining the attitudes and practices of students before and after exposure to the CD-ROM format. METHODOLOGY: An anonymous survey was distributed to students in the second-year introductory surgery course on the first day of class and again on the last day of class. Responses to questions were tabulated, response frequencies determined, and Chi-square analysis performed to determine differences between initial and final responses. RESULTS: On the final survey, 89 per cent of students responded that the instructional videos definitely helped them prepare for the laboratory, and 77 per cent responded that they were more likely to practice techniques learned from the CD-ROM videos than those learned from traditional study materials. The majority of students believed that the CD-ROM improved both the course (60 per cent) and their learning experience (62 per cent) as compared to traditional paper notes. CONCLUSIONS: Including instructional videos on the CD-ROM enhanced the educational experience of the students by promoting preparedness for laboratories and promoting practice of techniques learned from the videos outside of the laboratory.     

Special medical applications of computers

The use of small computers for assistance in medical diagnosis is examined in light of their limitations, particularly in a veterinary clinical setting. Various approaches to these problems are discussed with an eye towards "appropriate technology" for the veterinary practice. The author describes two "expert systems" he devised that enable the small computer to aid in the analysis of laboratory data and in the clinical diagnosis of veterinary patients.     

Handheld computers in veterinary medical education: a view from human medical education

Handheld computers are widely used in clinical practice, and their use in both human medical education and veterinary medical education is increasing, especially, for the former, in activities involving point-of-care access. This article references the insights that can be obtained from the usage and activities that are gaining a strong foothold in human medical education. Handheld computer technology gives students access to a large and changing knowledge base for clinical practice, especially when they are geographically dispersed. Differences in use between education and practice largely relate to the importance clinicians place on patient information. Student use focuses on progress mapping and ready access to clinical reference material. Suggestions are made for future use in medical education.     

Attitudes of veterinary medical students and medical students toward collaborative learning: an experiment

This study measured the attitudes of 55 medical students and 30 veterinary medical students as they participated in an experiment of collaborative teaching and learning about basic surgical skills. Two parallel forms of an attitude questionnaire were developed, with three subscales: confidence in one's own surgical skill; collaboration with the other type of student; and inter-professional collaboration in general. These attitude scales were administered before and after an experiment involving the veterinary medical students teaching the medical students incision and exploratory laparoscopy in a laboratory setting using live rabbits. After the experiment, measures of the medical students' attitudes had increased significantly on all three subscales. Measures of the veterinary students' attitudes increased significantly on two subscales but declined on the subscale of inter-professional collaboration.     

Exploring student attitudes to directed self-learning online through evaluation of an Internet-based biomolecular sciences resource

RATIONALE FOR THE STUDY: In 2000, funding was awarded by the University of Glasgow's Learning and Teaching Development Fund (L&TDF) for the authors to develop an interactive, online learning resource for veterinary biomolecular sciences teaching. This course is a core component of the veterinary undergraduate curriculum at the university. Evaluations were carried out to gauge students' experiences of using the resource as a basis for exploring students' attitudes toward online, independent learning. METHODOLOGY: Peers were asked to review the design and content of four modules, also evaluated by students using questionnaires and focus group discussions. Additionally, students were observed using the modules. Both first-year students and second-year direct-entry students (i.e., students entering the veterinary program with advanced training) participated in the evaluation, which allowed for some comparison between the groups. One cohort used the modules independently, and their responses were compared with the cohorts that used the modules in scheduled classes. RESULTS AND CONCLUSIONS: The evaluations indicate that this is a useful resource that could act as a template for other courses within the veterinary undergraduate curriculum, particularly for learning of basic sciences. On average, first-year and timetabled students rated the program more highly overall, rated the program more highly in relation to previous instruction, and rated tutor presence as more important than second-year direct-entry and independent students did. The lower rating given to tutor presence by second-year direct-entry and independent students indicates that they are more confident using the modules without tutor supervision.     

Stress management interventions for veterinary students

Two-hundred-and-eighty-nine veterinary students from all four years of the University of Tennessee, College of Veterinary Medicine (UTCVM) were invited to complete the Derogatis Stress Profile (DSP)1 and an original Demographic Data Profile (DDP). The DSP assessed the students' current experiences of perceived stress, and the DDP was designed to gather information about students' academic year, their living situations, their financial situations, their interest area within the veterinary medical profession, and their current methods of coping with stress. These data were gathered as a baseline measure of veterinary medical students' perceived level of stress and quality of life. In an earlier study, data were also collected from faculty and staff about the perceived quality of the climate and culture of the veterinary college. The results of the DSP and DDP suggest that, although veterinary students at UTCVM do not experience significant levels of stress overall, they do report higher levels of subjective stress, time pressure, and depression than the general population. The more companion animals that veterinary students cared for in their personal lives, the more likely they were to report higher levels of perceived stress. Lastly, there were significant differences between genders, with female veterinary students reporting higher levels of perceived stress than their male counterparts. The preliminary results of the climate and culture data suggest that faculty and staff of the veterinary college individually feel that they are cared for in the work environment and collectively believe that the college strives for excellence.     

The first-year veterinary student and mental health: the role of common stressors

The present study evaluated the impact of academic and non-academic stressors on depression levels in a longitudinal investigation of 78 first-year veterinary medical students enrolled at Kansas State University (KSU). Students completed the Center for Epidemiological Studies Depression Scale during their first and second semesters to evaluate the dependent variable, depression. Students provided information about specific stressors and relevant demographic variables that yielded independent variables. One-third of veterinary medical students surveyed in their first and second semesters reported depression levels above the clinical cut-off; 15% of the sample experienced an increase in depression of at least one standard deviation, despite the apparent stability of the proportion of students experiencing significant depressive symptoms. Students whose depression scores increased by one standard deviation or who maintained scores above the clinical cut-off score were identified as struggling. Struggling students reported more first-semester homesickness and academic concerns, along with difficulty fitting in with peers and poorer perceived physical health during the second semester. This study helped to identify those students most prone to develop or maintain concerning depression scores. The discussion section addresses specific suggestions for intervening with struggling students.     

Student perceptions of an animal-welfare and ethics course taught early in the veterinary curriculum

Animal welfare and veterinary ethics are two subjects that have been acknowledged as necessary for inclusion in the veterinary curriculum. In fact, the American Veterinary Medical Association (AVMA) Council on Education has mandated that veterinary ethics be taught to all students in US veterinary colleges. Animal welfare was recently included in the US veterinarian's oath, and AVMA established a committee to create a model curriculum on the subject. At US veterinary colleges, the number of animal-welfare courses has more than doubled from five in 2004 to more than 10 in 2011. How and what is taught with regard to these two subjects may be as important as whether they are taught at all, and a variety of approaches and varying amounts and types of content are currently being offered on them. At Michigan State University's College of Veterinary Medicine, students were introduced to animal welfare and veterinary ethics during their first semester in a mandatory two-credit course. To assess their perception of the course, students completed an online evaluation at the end of the semester. Most students found the course to be challenging and effective and felt that they improved their ability to identify and discuss ethical dilemmas.     

An instructional intervention to encourage effective deep collaborative learning in undergraduate veterinary students

In recent years, veterinary education has received an increased amount of attention directed at the value and application of collaborative case-based learning. The benefit of instilling deep learning practices in undergraduate veterinary students has also emerged as a powerful tool in encouraging continued professional education. However, research into the design and application of instructional strategies to encourage deep, collaborative case-based learning in veterinary undergraduates has been limited. This study focused on delivering an instructional intervention (via a 20-minute presentation and student handout) to foster productive, collaborative case-based learning in veterinary education. The aim was to instigate and encourage deep learning practices in a collaborative case-based assignment and to assess the impact of the intervention on students' group learning. Two cohorts of veterinary students were involved in the study. One cohort was exposed to an instructional intervention, and the other provided the control for the study. The instructional strategy was grounded in the collaborative learning literature and prior empirical studies with veterinary students. Results showed that the intervention cohort spent proportionally more time on understanding case content material than did the control cohort and rated their face-to-face discussions as more useful in achieving their learning outcomes than did their control counterparts. In addition, the perceived difficulty of the assignment evolved differently for the control and intervention students from start to end of the assignment. This study provides encouraging evidence that veterinary students can change and enhance the way they interact in a group setting to effectively engage in collaborative learning practices.     

Study of the influence of veterinary medical education on the moral development of veterinary students

Although veterinary medicine endorses high moral character and adherence to a code of ethics, to our knowledge, virtually no studies have examined the influence of veterinary medical education on the moral development of its students. Using the Kohlberg standard moral judgment interview, this study examined that relationship in a sample of 20 veterinary medical students (16.0% of the veterinary college's student body). The students were tested at the beginning and at the end of their veterinary medical education to determine whether their moral reasoning scores had increased to the same extent as those of other postgraduate students. It was found that normally expected increases in moral reasoning did not occur over the four years of veterinary medical education for these students, suggesting that their veterinary medical educational experience somehow inhibited their moral reasoning ability rather than facilitated it. With a range of moral reasoning scores between 313 and 436, the mean increase from first year to fourth year of 12.5 points was not statistically significant. Statistical analysis revealed no significant correlations between the moral reasoning scores on age or gender, although there were significant correlations with Medical College Admissions Test scores and grade point average scores.     

Development and evaluation of a leadership program for veterinary students

Leadership skills are important for many facets of professional life, but no known leadership training programs exist in North American veterinary schools. It was the purpose of this project to develop, deliver, and evaluate a leadership program for first-year veterinary students. Leadership attributes emphasized in the course included effective communication, openness to learning from others, self-awareness, commitment beyond self-interest, motivation, decision making, understanding issue complexity, and team building. The five-day course was delivered to 21 new veterinary students randomly selected just prior to their first-year orientation in the fall of 2000. Participants ranked themselves higher than non-participants in a post-course evaluation on their ability to be effective leaders. Participants reported an increase in self-confidence and a clearer understanding of their leadership roles. Participants also noted new support systems among co-participants and expressed a new ability to consider complex issues more broadly. Most reported that they frequently used enhanced skills in giving and receiving feedback and team building. Other leadership tools identified as valuable included negotiation, group dynamics, a structured approach to problem solving, time management, and an awareness of personal learning style preferences as a means to improve communication.     

Integrating a bovine rectal palpation simulator into an undergraduate veterinary curriculum

There are problems associated with teaching bovine rectal palpation to undergraduate veterinary students. The students need opportunities to examine enough cows to develop the required skills, but increasing student numbers and limitations on access to cows have made this more and more difficult to achieve. A virtual reality-based teaching tool, the Bovine Rectal Palpation Simulator, has been developed as a supplement to existing training methods. The student palpates computer generated virtual models of the bovine reproductive tract while interacting with a haptic (touch feedback) device. During training sessions, the instructor follows the student's actions inside the virtual cow on the computer screen and gives instruction. A trial integration of the simulator into the fourth-year bovine reproduction course was undertaken at the University of Glasgow Veterinary School during the 2003/2004 academic year. Students were offered two training sessions, and feedback was gathered using questionnaires. In the first session, all students were taught a range of basic skills using a standardized teaching protocol. The second training session was customized to each student's learning needs and included practice in dealing with a range of on-farm scenarios. Student feedback indicated that the training had been useful for learning various aspects of bovine rectal palpation and provided information that helped in the further development of the simulator as a teaching tool.     

Veterinary students' perceptions of their day-one abilities before and after final-year clinical practice-based training

The present study evaluated the impact of final-year clinical practice-based training on veterinary students' perceptions of competence in "Day One" abilities by administering a pre- and post-training self-assessment checklist. This study also investigated the influence of student demographics on their perceptions of satisfaction about their own knowledge and skills and preparedness for practice. Perceptions regarding the usefulness of the checklist as a self-audit tool were also sought. Final year students (N=85) were surveyed on commencement and upon completion of the training using a checklist that had been adapted from the list of essential new-graduate abilities that was developed by the Royal College of Veterinary Surgeons and adopted by the Australasian Veterinary Boards Council. Significant improvements in student perceptions of competence were observed for 38 of the 41 abilities. Students' satisfaction with their knowledge and skill base and their perceptions of preparedness for practice were only weakly correlated with overall perceptions of competence for individual ability items and did not vary significantly with student age, gender, background, intended field and location of work, or with their work experience as veterinary nurses-if any-while studying. Two thirds of students believed that access to the self-assessment checklist on commencement of the training helped them identify areas for improvement before graduation. This article concludes that clinical practice-based training results in considerable improvement in senior veterinary students' perceptions of competence in Day One abilities and that a self-assessment checklist may help students guide their learning. Results from the present study may be useful for veterinary schools as they develop or enhance strategies used for outcomes assessment.     

The use of information technology in large animal veterinary education

To facilitate large animal veterinary education, information technology has to connect the classroom to the farm. Technology needs to be portable, durable, and cost-effective. Dairy production medicine was one of the first areas in veterinary medicine to use computers to manage large sets of milk production-related data. Now equine practice has embraced technology in almost every diagnostic imaging methodology. The personal desktop assistant (PDA) has allowed students to take large volumes of information with them during clinical rotations. The technology is advancing so quickly that it is difficult to keep up with new software and hardware developments, let alone purchase the most current versions. This article reviews information technology as it is used in large animal practice and, consequently, in large animal veterinary education.
