The total number of anatomy teaching hours has declined in medical courses worldwide. Conversely, face‐to‐face teaching in undergraduate neuroanatomy at Macquarie University increased by 50% in 2011. Our aim was to investigate whether this influenced student performance and overall satisfaction with the course. One hundred eighty‐one students consented to participate in this study. A questionnaire was administered to rate the course, and final grades from the old and new unit cohorts were compared. The old and new unit cohorts did not differ in their final grades (P = 0.249). However, the new unit cohort rated their knowledge of the material higher compared to the old unit cohort (P = 0.013), and reported higher levels of satisfaction with the course (P < 0.001). In an era in which teaching time for anatomy has been reduced at tertiary institutions, and there is much lamenting of the effect this will have, there is a paucity of literature on whether the decrease really influences neuroanatomical knowledge. This is the first study, to the best of our knowledge, to show that an increase in total face‐to‐face teaching hours does not improve student grades, but does increase student satisfaction with the course.

In light of the current shifts in medical education from traditional lectures to more active teaching modalities, a peer-teaching program was introduced to a compulsory, second-year neuroanatomy course. A cross-sectional survey of 527 medical students in the six-year medical program of the National and Kapodistrian University of Athens was administered. The primary aim of the survey, which was distributed to second- through sixth-year medical students, who had completed the neuroanatomy course, was to assess student perception of peer teachers (PTs). Across the five years assessed, students increasingly acknowledged the contribution of PTs to their learning (P < 0.001). Attributes of PTs (e.g., contribution to learning, motivation, effective usage of material, and team environment) were significantly related to the student's opinion of the importance of laboratory activities (P < 0.001). Students who received “average” final grades scored the importance of laboratory exercises, and by inference PTs, significantly lower than students who received “excellent” final grades (P < 0.05). The amount of training that PTs had received was also significantly related to student perceptions of a PT's contribution. Better trained PTs were associated with significantly higher scores regarding learning, motivation, and positive environment compared to less trained PTs (P < 0.05). The results of the present study show that peer-teaching was well received by students attending the neuroanatomy course. While the results express the evolution of the program across the years, the findings also show that learners believed that PTs and the laboratory program contributed significantly to their understanding of neuroanatomy.  相似文献

Many institutions rely upon prosection-based laboratories as more resource-efficient and time-effective alternatives to traditional cadaver dissection for human anatomy education. To facilitate growing enrollment numbers despite resource limitations, the University of Guelph (a non-medical institution) introduced a modified “stepwise” prosection-based laboratory cohort to supplement a dissection-based course. In this design, all students attended the same lectures, but those in the dissection-based cohort learned by performing regional dissections and students in the prosection-based cohort studied from those dissections. Prosection students thereby witnessed a “slow reveal” of structures throughout the course. This study compared the perceived course experiences, student approaches to learning, and academic performance between the two groups. Multiple linear regression analyses were used to isolate the effect of the laboratory environment on student approaches to learning and academic performance from demographic and situational covariates. Both groups reported positive course experience ratings and high average final grades that were not statistically dissimilar (P > 0.05), increased reliance on deep approaches to learning (P = 0.002), and decreased reliance on surface approaches to learning (P = 0.023). When controlling for covariates, participation in dissection had small but statistically significant positive associations with deep approaches to learning (P = 0.043), performance on laboratory oral assessments (P < 0.001), and average final grades (P = 0.039). Ultimately, both designs promoted meaningful learning and desirable performance outcomes, indicating that both dissection and stepwise prosection have the potential to facilitate high quality human anatomy instruction.  相似文献

The literature reports that using Learning Recording Systems (LRS) is usually well received by students but that the pedagogical value of LRS in academic settings remains somewhat unclear. The primary aim of the current study is to document students' perceptions, actual pattern of usage, and impact of use of LRS on students' grade in a dental gross and neuroanatomy course. Other aims are to determine if students' learning preference correlated with final grades and to see if other factors like gender, age, overall academic score on the Dental Aptitude Test (DAT), lecture levels of difficulty, type of lecture, category of lecture, or teaching faculty could explain the impact, if any, of the use of LRS on the course final grade. No significant correlation was detected between the final grades and the variables studied except for a significant but modest correlation between final grades and the number of times the students accessed the lecture recordings (r=0.33 with P=0.01). Also, after adjusting for gender, age, learning style, and academic DAT, a significant interaction between auditory and average usage time was found for final grade (P=0.03). Students who classified themselves as auditory and who used the LRS on average for fewer than 10 minutes per access, scored an average final grade of 16.43 % higher than the nonauditory students using the LRS for the same amount of time per access. Based on these findings, implications for teaching are discussed and recommendations for use of LRS are proposed. Anat Sci Educ 6: 376–384. © 2013 American Association of Anatomists.  相似文献

Three-dimensional virtual technology (3DVT) educational tools and peer-tutoring have proven to be effective teaching strategies in improving student learning outcomes. The purpose of this study was threefold: (1) compare the anatomy academic performance between underrepresented minority (URM) and non-minority (non-URM) students, (2) compare the voluntary use of 3DVT dissection videos and peer-mentoring between these two cohorts, and (3) estimate the association between the use of these teaching strategies on anatomy examinations and course grades at a school of physical therapy. Three-dimensional virtual technology narrated dissection videos and peer-mentoring were made available to all students. Time accessing the video and attending peer-mentoring sessions was measured throughout the course for all students. Three practical and four written examinations and the final course grade were calculated. Numerous one-way ANOVAs were used to compare examination/course grades between student cohorts (URM and non-URM) and usage of the two educational strategies (3DVT and peer-mentoring). Multiple linear regressions were performed with teaching strategies as predictors and grades as outcomes. Underrepresented minority students demonstrated significantly lower practical examination scores (P = 0.04), lower final course grades (P = 0.01), and a greater use of mentorship hours (P = 0.001) compared to non-URM. The regression models with both predictors (3DVT and peer-mentoring) combined demonstrated the greatest association with grades for both URM and non-URM. For both groups of students, the association between predictors and practical examination scores, although fair, was not statistically significant. Peer-mentoring seems to be the most effective teaching strategy in helping URM students succeed in anatomy.  相似文献

Computer‐aided learning (CAL) is an integral part of many medical courses. The neuroscience course at Oxford University for medical students includes CAL course of neuroanatomy. CAL is particularly suited to this since neuroanatomy requires much detailed three‐dimensional visualization, which can be presented on screen. The CAL course was evaluated using the concept of approach to learning. The aims of university teaching are congruent with the deep approach—seeking meaning and relating new information to previous knowledge—rather than to the surface approach of concentrating on rote learning of detail. Seven cohorts of medical students (N = 869) filled in approach to learning scale and a questionnaire investigating their engagement with the CAL course. The students' scores on CAL‐course‐based neuroanatomy assessment and later university examinations were obtained. Although the students reported less use of the deep approach for the neuroanatomy CAL course than for the rest of their neuroanatomy course (mean = 24.99 vs. 31.49, P < 0.001), deep approach for CAL was positively correlated with neuroanatomy assessment performance (r = 0.12, P < 0.001). Time spent on the CAL course, enjoyment of it, the amount of CAL videos watched and quizzes completed were each significantly positively related to deep approach. The relationship between deep approach and enjoyment was particularly notable (25.5% shared variance). Reported relationships between deep approach and academic performance support the desirability of deep approach in university students. It is proposed that enjoyment of the course and the deep approach could be increased by incorporation of more clinical material which is what the students liked most.

The authors describe and evaluate a method to motivate medical students to maximize the effectiveness of dissection opportunities by using In‐Course‐Assessments (ICAs) to encourage teamwork. A student's final mark was derived by combining the group dissection mark, group mark for questions, and their individual question mark. An analysis of the impact of the ICA was performed by comparing end of module practical summative marks in student cohorts who had, or had not, participated in the ICAs. Summative marks were compared by two‐way ANOVA followed by Dunnets test, or by repeated measures ANOVA, as appropriate. A cohort of medical students was selected that had experienced both practical classes without (year one) and with the new ICA structure (year two). Comparison of summative year one and year two marks illustrated an increased improvement in year two performance in this cohort. A significant increase was also noted when comparing this cohort with five preceding year two cohorts who had not experienced the ICAs (P <0.0001). To ensure that variation in the practical summative examination was not impacting on the data, a comparison was made between three cohorts who had performed the same summative examination. Results show that students who had undertook weekly ICAs showed significantly improved summative marks, compared with those who did not (P <0.0001). This approach to ICA promotes engagement with learning resources in an active, team‐based, cooperative learning environment.

Blended learning has become increasingly common in higher education. Recent findings suggest that blended learning achieves better student outcomes than traditional face‐to‐face teaching in gross anatomy courses. While face‐to‐face content is perceived as important to learning there is less evidence for the significance of online content in improving student outcomes. Students enrolled in a second‐year anatomy course from the physiotherapy (PT), exercise physiology (EP), and exercise science (ES) programs across two campuses were included (n = 500). A structural equation model was used to evaluate the relationship of prior student ability (represented by grade in prerequisite anatomy course) and final course grade and whether the relationship was mediated by program, campus or engagement with the online elements of the learning management system (LMS; proportion of documents and video segments viewed and number of interactions with discussion forums). PT students obtained higher grades and were more likely to engage with online course materials than EP and ES students. Prerequisite grade made a direct contribution to course final grade (P < 0.001) but was also mediated by engagement with LMS videos and discussion forums (P < 0.001). Student learning outcomes in a blended anatomy course can be predicted the by level of engagement with online content. Anat Sci Educ 11: 471–477. © 2017 American Association of Anatomists.  相似文献

Lincoln Memorial University‐DeBusk College of Osteopathic Medicine (LMU‐DCOM) offers an optional three‐week summer Anatomy Boot Camp course (ABC) to facilitate students' transition into medical school and promote retention of anatomy subject matter. The pre‐matriculation program is a supplemental instruction course that utilizes a small group learning format. Boot camp instruction is led by teaching assistants and two anatomy professors. Enrollees gain early exposure to Medical Gross Anatomy (MGA) course subject matter, which is taught in the fall semester, and learn study skills necessary to excel in medical school. No grade is assigned for the course, therefore participants can study without the fear of potentially affecting grades. This study evaluates the effectiveness of the LMU‐DCOM ABC course using data from four consecutive summers. Independent two‐sample t‐tests were used to compare ABC to non‐ABC students for the following variables: incoming grade point average (GPA) and Medical College Admission Test® (MCAT®) scores, MGA written and laboratory practical examination grades, and final MGA course grade. Additionally, a 26‐question survey was administered to 2012–2014 boot camp participants. There were no significant differences in incoming GPA and MCAT scores. However, boot campers scored significantly higher on the first two lecture and laboratory examinations (P < 0.05) for each year of the study. Thereafter scores varied less, suggesting a faster head start for boot camp participants. Mean MGA final grade was on average 3% higher for the boot camp cohort. The survey feedback supports that the ABC course assists with the academic and social transition into medical school. Anat Sci Educ 10: 215–223. © 2016 American Association of Anatomists.  相似文献

A novel three-dimensional tool for teaching human neuroanatomy   总被引：1，自引：0，他引：1  
Three‐dimensional (3D) visualization of neuroanatomy can be challenging for medical students. This knowledge is essential in order for students to correlate cross‐sectional neuroanatomy and whole brain specimens within neuroscience curricula and to interpret clinical and radiological information as clinicians or researchers. This study implemented and evaluated a new tool for teaching 3D neuroanatomy to first‐year medical students at Boston University School of Medicine. Students were randomized into experimental and control classrooms. All students were taught neuroanatomy according to traditional 2D methods. Then, during laboratory review, the experimental group constructed 3D color‐coded physical models of the periventricular structures, while the control group re‐examined 2D brain cross‐sections. At the end of the course, 2D and 3D spatial relationships of the brain and preferred learning styles were assessed in both groups. The overall quiz scores for the experimental group were significantly higher than the control group (t(85) = 2.02, P < 0.05). However, when the questions were divided into those requiring either 2D or 3D visualization, only the scores for the 3D questions were significantly higher in the experimental group (F1,85= 5.48, P = 0.02). When surveyed, 84% of students recommended repeating the 3D activity for future laboratories, and this preference was equally distributed across preferred learning styles (χ2 = 0.14, n.s.). Our results suggest that our 3D physical modeling activity is an effective method for teaching spatial relationships of brain anatomy and will better prepare students for visualization of 3D neuroanatomy, a skill essential for higher education in neuroscience, neurology, and neurosurgery.

Neuroanatomy is considered to be one of the most difficult anatomical subjects for students. To provide motivation and improve learning outcomes in this area, clinical cases and neurosurgical images from diffusion tensor imaging (DTI) tractographies produced using an intraoperative magnetic resonance imaging apparatus (MRI/DTI) were presented and discussed during integrated second‐year neuroanatomy, neuroradiology, and neurosurgery lectures over the 2008–2011 period. Anonymous questionnaires, evaluated according to the Likert scale, demonstrated that students appreciated this teaching procedure. Academic performance (examination grades for neuroanatomy) of the students who attended all integrated lectures of neuroanatomy, was slightly though significantly higher compared to that of students who attended these lectures only occasionally or not at all (P=0.04). Significantly better results were obtained during the national progress test (focusing on morphology) by students who attended the MRI/DTI‐assisted lectures, compared to those who did so only in part or not at all, compared to the average student participating in the national test. These results were obtained by students attending the second, third and, in particular, the fourth year (P≤0.0001) courses during the three academic years mentioned earlier. This integrated neuroanatomy model can positively direct students in the direction of their future professional careers without any extra expense to the university. In conclusion, interactive learning tools, such as lectures integrated with intraoperative MRI/DTI images, motivate students to study and enhance their neuroanatomy education.

The present study evaluated the students' psychological well-being, experiences, performance, and perception of learning regional anatomy remotely. A regional anatomy remote learning curriculum was designed and learning materials were delivered virtually to 120 undergraduate medical students at Jinan University, China. All the students consented and voluntarily participated in this study by completing self-administered online questionnaires including the Zung's Self-Rating Anxiety and Depression Scales at the beginning and end of the learning session. A subset participated in focus group discussions. Most of the students (90.0%) positively evaluated the current distance learning model. More than 80% were satisfied with the content arrangement and coverage. Many students preferred virtual lectures (68.2%) and videos showing dissections (70.6%) during the distance learning sessions. However, writing laboratory reports and case-based learning were the least preferred modes of learning as they were only preferred by 23.2% and 14.1% of the students, respectively. There was no significant lockdown-related anxiety or depression reported by students using depression and anxiety scales as well as feedback from focus group discussions. The surveyed students' confidence scores in distance learning were significantly higher after 5 weeks than at the beginning of the session (3.05 ± 0.83 vs. 3.70 ± 0.71, P < 0.05). Furthermore, the present results showed no significant differences between the current group's academic performance in the unit tests as well as the final overall evaluation for different parts of the course compared to that of the previous year's cohort. The findings above were congruent with focus group discussion data that the use of the online teaching platform for regional anatomy significantly improved the students' confidence in virtual and self-directed learning and did not negatively affect their academic performance.  相似文献

The present study investigated differences in the effectiveness of instructors from a variety of departments who taught the same course in both intensive and traditional formats within the same year, while controlling for many confounding variables. Results indicated that intensive courses did not significantly differ from traditional courses in overall instructor ratings on student evaluations of teaching effectiveness when confounding variables were taken into account. Conversely, intensive courses received significantly higher overall course ratings on student evaluations than did traditional courses, even after controlling for class size and probable grade in course. These findings provide further evidence that negative beliefs concerning intensive courses may be unjustified, and intensive courses may be as or more effective than those presented in traditional formats.  相似文献

Visualizing anatomical structures and functional processes in three dimensions (3D) are important skills for medical students. However, contemplating 3D structures mentally and interpreting biomedical images can be challenging. This study examines the impact of a new pedagogical approach to teaching neuroanatomy, specifically how building a 3D‐model from oil‐based modeling clay affects learners’ understanding of periventricular structures of the brain among undergraduate medical students in Colombia. Students were provided with an instructional video before building the models of the structures, and thereafter took a computer‐based quiz. They then brought their clay models to class where they answered questions about the structures via interactive response cards. Their knowledge of periventricular structures was assessed with a paper‐based quiz. Afterward, a focus group was conducted and a survey was distributed to understand students’ perceptions of the activity, as well as the impact of the intervention on their understanding of anatomical structures in 3D. Quiz scores of students that constructed the models were significantly higher than those taught the material in a more traditional manner (P < 0.05). Moreover, the modeling activity reduced time spent studying the topic and increased understanding of spatial relationships between structures in the brain. The results demonstrated a significant difference between genders in their self‐perception of their ability to contemplate and rotate structures mentally (P < 0.05). The study demonstrated that the construction of 3D clay models in combination with autonomous learning activities was a valuable and efficient learning tool in the anatomy course, and that additional models could be designed to promote deeper learning of other neuroanatomy topics.

Multiple-choice (MC) anatomy “spot-tests” (identification-based assessments on tagged cadaveric specimens) offer a practical alternative to traditional free-response (FR) spot-tests. Conversion of the two spot-tests in an upper limb musculoskeletal anatomy unit of study from FR to a novel MC format, where one of five tagged structures on a specimen was the answer to each question, provided a unique opportunity to assess the comparative validity and reliability of FR- and MC-formatted spot-tests and the impact on student performance following the change of test format to MC. Three successive year cohorts of health science students (n = 1,442) were each assessed by spot-tests formatted as FR (first cohort) or MC (following two cohorts). Comparative question difficulty was assessed independently by three examiners. There were more higher-order cognitive skill questions and more of the course objectives tested in the MC-formatted tests. Spot-test reliability was maintained with Cronbach’s alpha reliability coefficients ≥ 0.80 and 80% of the MC items of high quality (having point-biserial correlation coefficients > 0.25). These results also demonstrated guessing was not an issue. The mean final score for the MC-formatted cohorts increased by 4.9%, but did not change for the final theory examination that was common to all three cohorts. Subgroup analysis revealed that the greatest change in spot-test marks was for the lower-performing students. In conclusion, our results indicate spot-tests formatted as MC are suitable alternatives to FR tests. The increase in mean scores for the MC-formatted spot-tests was attributed to the lower demand of the MC format.  相似文献

This investigation focused on the development of a study module called Pedagogical Ethics (PEd) in teacher education at the university level. The main aim was to examine both experiences of the study process and learning results. The quasi‐experimental design was developed by student teachers. The experimental group ( n = 32) attended a web‐based PEd course designed using the WebCT tool, while the control group ( n = 65) studied the same material in the traditional way. The same person was the teacher in both teaching–learning modes. Both groups evaluated the content and the mode as excellent, but the traditional teaching–learning mode was slightly more effective than the web‐based course. The quantity and quality of the technology‐mediated discussions concerning the ethical case studies were uneven. The differences in learning results between the experimental and control groups were not statistically significant.  相似文献

Tuebingen's Sectio Chirurgica (TSC) is an innovative, interactive, multimedia, and transdisciplinary teaching method designed to complement dissection courses. The Tuebingen's Sectio Chirurgica (TSC) allows clinical anatomy to be taught via interactive live stream surgeries moderated by an anatomist. This method aims to provide an application‐oriented approach to teaching anatomy that offers students a deeper learning experience. A cohort study was devised to determine whether students who participated in the TSC were better able to solve clinical application questions than students who did not participate. A total of 365 students participated in the dissection course during the winter term of the 2012/2013 academic year. The final examination contained 40 standard multiple‐choice (S‐MC) and 20 clinically‐applied multiple‐choice (CA‐MC) items. The CA‐MC items referred to clinical cases but could be answered solely using anatomical knowledge. Students who regularly participated in the TSC answered the CA‐MC questions significantly better than the control group (75% and 65%, respectively; P < 0.05, Mann‐Whitney U test). The groups exhibited no differences on the S‐MC questions (85% and 82.5%, respectively; P > 0.05). The CA‐MC questions had a slightly higher level of difficulty than the S‐MC questions (0.725 and 0.801, respectively; P = 0.083). The discriminatory power of the items was comparable (S‐MC median Pearson correlations: 0.321; CA‐MC: 0.283). The TSC successfully teaches the clinical application of anatomical knowledge. Students who attended the TSC in addition to the dissection course were able to answer CA‐MC questions significantly better than students who did not attend the TSC. Thus, attending the TSC in addition to the dissection course supported students' clinical learning goals. Anat Sci Educ 10: 46–52. © 2016 American Association of Anatomists.  相似文献

Knowledge of dental anatomy is of great importance in the practice of dentistry, especially in oral rehabilitation, because without this knowledge, professional practice is not possible. Dental carving plays a major role in training dental students as it develops their manual dexterity. This randomized controlled trial aimed to evaluate the influence of didactic‐theoretical reinforcement on the theoretical and practical knowledge of dental anatomy of preclinical students by examining the quality of the anatomical restorations performed by these students before and after a didactic‐theoretical reinforcement. For the evaluation of theoretical knowledge, a questionnaire with closed questions about dental anatomy was used. To evaluate the effect of didactic reinforcement on dental carvings, two groups of 15 preclinical students were assessed. Experimental group (G1) received a three‐hour theoretical tutoring on dental anatomy, while the control group (G2) did not. The dental carving scores obtained by the two different groups were compared using Student's t‐test. Cohen's d was used to estimate the effect sizes between groups. The frequency of correct answers given for each theoretical knowledge question was compared in each group using Fisher's exact test. T‐test was also used to compare the means of the two groups' final scores of theoretical evaluations. To compare these final scores obtained in both carving and theoretical tests, a principal component analysis was performed with different items assessed in each test to obtain factor loading scores and a final weighted score, where factor loadings were considered for each item. Weighted scores were compared using t‐test. Also, scores obtained during the head and neck course were assessed and compared using t‐test. Spearman's correlation test was used to assess the correlation between scores obtained prior to the anatomy course and scores obtained in the dental carving exercise. The theoretical evaluation revealed no significant difference between the grades (mean ± SD) of G1 (85.1 ± 6.6%) and G2 (86.2 ± 9.1%) with the grades of a baseline test that was previously obtained when students submitted to the study (P = 0.725). Regarding the tooth carving assessment, the dental carving quality by students of G1 has significantly improved, except for tooth #23 (P = 0.096). Theoretical reinforcement of dental anatomy seems to improve the students' carving performance but does not enhance their knowledge about dental anatomy.

Near‐peer teaching involves more experienced students acting as tutors and has been widely used in anatomy education. This approach has many advantages for the learner due to the social and cognitive congruence they share with the teacher, however, the influence of distance between the teacher and learner on these congruences has yet to be explored. The aim of this study was to compare the attitudes and perceptions of the student learner towards neuroanatomy review sessions taught by either a senior medical student or a junior doctor. The students were randomly assigned to an allocated tutor. All tutors used standardized material and had access to identical resources. The type of allocated tutor was swapped between the two teaching sessions and 99 student feedback forms were collected in total. The rating for the overall quality of the teaching session was not significantly different between the junior doctors and senior medical students (P = 0.11). However, criteria closely relating to social and cognitive congruence such as “enjoyment of the session,” “delivery of the teaching,” and “was it a good use of time” were all rated significantly higher for the senior medical students (P < 0.05). The results of this study suggest that small increases in distance along the near‐peer teaching spectrum have an impact upon the student's perception of their learning experience. While all teachers were suitable role models it appears that junior doctors are too far removed from their own undergraduate experiences to share congruences with pre‐clinical medical students.
