Effectiveness of problem-based learning strategies compared to conventional anatomy teaching approaches.

Objectives: To determine the effectiveness of problem-based learning compared to conventional teaching strategies, and to determine the impact of sub-disciplines of Anatomy on learning outcomes of the subject. METHODS: The cross-sectional, descriptive study was conducted at Bahria University Health Sciences, Karachi, from August to October 2022, and comprised 1st and 2nd year medical students and 1st year dental students of either gender who were being taught by the hybrid method including both conventional and problem-based learning strategies. Data was collected using a questionnaire circulated through Google Forms. It had close-ended questions that were scored on a Likert scale. Anatomy sub-disciplines explored were gross, embryology and histology. Data was analysed using SPSS 23. RESULTS: Of the 251 subjects, 125(49.8%) were males and 126(50.2%) were females. The overall age ranged aged 18- 23 years. There were 115(45.8%) 1st year medical students, 111(44.2%) 2nd year medical students and 25(10%) 1st year dental students. Among 1st year medical students 60(52.17%), among 2nd year medical students 64(57.6%) and among 1st year dental students 14(56%) respondents favoured problem-based learning compared to conventional methodology. Highly significant results were obtained regarding need of topic revision (p<0.001), whether knowledge of conventional teaching method is enough for understanding the clinical scenarios (p=0.017, whether pictures shown during the problem-based learning sessions were enough for understanding anatomy (p=0.035), relevance of questions in oral structured practical examination (p=0.019) and viva (p=0.002). When the participants were asked regarding the anatomy sub-discipline that required revision for comprehensive learning, 72(28.3%) mentioned gross anatomy. CONCLUSIONS: Students considered problem-based learning to be more inducive in enhancing learning compared to conventional teaching.

The role of Vesalius and his contemporaries in the transfiguration of human anatomical science.

The understanding of human anatomy has been an endeavour spanning thousands of years from the Egyptians and Greeks in antiquity to the present day. Scholars and scientists have overcome great barriers to discover the inner workings and complexities of the human body, from personal challenges and prejudices to obstacles placed by society. Our present understanding of anatomy has accumulated over centuries, and progressive generations of physicians have contributed to the ever-growing evidence-based knowledge. This article explores the contributions made by Vesalius and his contemporaries in the first half of the sixteenth century. These enlightened scholars advanced anatomical knowledge and, perhaps more importantly, the scientific method, directly impacting the mindset and methodologies of future anatomists. Individuals such as Berengario da Carpi and Gabriele Falloppio produced bodies of work during their lifetime that were not only important in disputing the teachings of Galen of Pergamon, which had been accepted as almost unquestionable truths for a thousand years, but also instrumental in developing a new generation of scientists. The anatomists of the late renaissance were unable to resolve many of the factual inaccuracies of Galenic teaching but provided the groundwork for scientific thinking which future generations of anatomists benefited greatly from. The principles of documenting what is observed and establishing a methodical approach to question discrepancies in experiments would go on to influence physicians such as Harvey and Malpighi to investigate and draw correct conclusions in their research and ultimately advance our understanding of human anatomy to what it is today.

Use of a two-handed model to improve comprehension of ventricular outflow tract anatomy.

BACKGROUND: Mastering cardiac anatomy is a formidable obstacle in the learning process for cardiac electrophysiology trainees. The complex three-dimensional characteristics and contiguous relationship of the ventricular outflow tract are particularly difficult to visualize with the limited study methods available. The hands can recreate a morphology similar to the ventricular outflow tract; this study explored whether a two-handed model of the heart helps electrophysiology trainees improve their understanding of ventricular outflow tract anatomy. METHODS: After an initial assessment, trainees were randomly placed into variable and control groups. Subsequently, all trainees learned the outflow tract anatomy using routine methods, with the variable group receiving additional instruction using the two-handed model. One day and one week after the course conclusion, knowledge of the ventricular outflow tract anatomy was assessed for the participants in both groups. RESULTS: Thirty-eight trainees participated (19 in each group). The median scores obtained for the first, second, and third tests were 38 (24,55), 80 (70,86), and 75 (70,81) points, respectively. In the second test, trainees in the variable group had a mean score 6.8 points higher than those in the control group (p = 0.103); in the last test, the mean score was 9.7 points higher in the variable group than in the control group (p = 0.003). CONCLUSIONS: It is convenient to use hands to create a model representing the ventricular outflow tract. Trainees using this model had a better understanding and retention of the ventricular outflow tract anatomy compared to those of the control group.

Creation of 21st century anatomy facilities: designing facilities for integrated preclinical education in the Middle East.

BACKGROUND: The establishment of new anatomy facilities needs to accommodate a combination of modern teaching modalities that best align with evidence-based best teaching practices. This article describes the process in which our state-of-the-art anatomy laboratories were designed and implemented, and how these facilities support aspects of modern anatomy education. METHODS: A list of best practices for anatomy education in a modern medical curriculum was summarized from the literature. To assess student satisfaction, a survey related to student perception of the anatomy facilities (5-point Likert scale) was conducted. RESULTS: Our educational modalities include a broad range of teaching approaches. The Instructional Studio houses prosected and plastinated specimens, and cadaveric dissections are performed. Each of our three Dry Laboratories allow for active learning and interaction between small student groups. The Webinar Room acts as a conference room for departmental and online meetings, discussions with students, and dialogues with affiliated hospitals via the internet. The Imaging Center is equipped with a Sectra® medical educational platform, CAE Vimedix® Virtual Medical Imaging Ultrasound Training System, and Philipps Lumify® Ultrasound devices to train students to conduct and interpret sonographic images. Moreover, the Complete Anatomy® program is made available to all our students. CONCLUSION: The layout of our newly created Anatomy Facilities allows for all aspects of modern medical education mentioned in the literature. These educational modalities and teaching approaches are highly appreciated by our faculty and students. Moreover, these technologies allowed for a smooth transition from on-site anatomy teaching to online education during the COVID pandemic.

Pedagogical principles used by anatomy teachers to facilitate the teaching and learning of anatomy to physiotherapy undergraduates in the United Kingdom.

The teaching of anatomy for physiotherapy differs from other health professions, and yet there is lack of guidance for the best practice in the literature, especially within the United Kingdom (UK). The present study aimed to provide the most effective pedagogical guidance for teaching a typical anatomy curriculum for a three-year BSc Physiotherapy degree program within the UK. The research design used a constructivist grounded theory where semi-structured interviews were conducted with eight registered physiotherapists teaching anatomy to undergraduate physiotherapy students within the UK. The study generated 72,292 words of qualitative data that were thematically analyzed using Saldaña's coding techniques until data saturation was reached. The results had three main components: a pedagogical backdrop composed of five pedagogical issues, pedagogical approaches with its three sub-components and pedagogical timings of phases of when anatomical teaching was conducted across the three undergraduate physiotherapy degree programs. The cognitive load theory (CLT) best explained the results through five main pedagogical principles: spiral curriculum strategies, visual anatomical imagery, kinesthetic anatomical skills, strategies for teaching clinical physiotherapy anatomy, and using anatomical principles for metacognition. The study proposes a new modified version of CLT which acknowledges that newly acquired knowledge is fragile in novice learners, who have limited long-term memory capacities, and subsequently require regular revisitations, and also acknowledges kinesthetic input and germane cognitive load metacognition strategies. The study recommends appointing anatomy theme leads to take responsibility for the spiral curriculum approach across the 3 years and to introduce explicit anatomy teaching during the later clinical years.

Checklist-based active learning in anatomy demonstration sessions during the COVID-19 pandemic: Perception of medical students.

Human anatomy is an essential component of the medical curricula. Anatomy education has been significantly affected during the COVID-19 pandemic. The aim of this study was to explore student's perceptions on a blended learning approach using Checklist-based Active Learning in Anatomy Demonstration Sessions (CALADS) as a method in comparison to the two previously used methods; namely face-to-face Structured Problem-Related Anatomy Demonstrations (SPRAD) and online anatomy learning. A comparative, cross-sectional, survey-based study was conducted. The survey was composed of 13 questions that explored preference of learning anatomy in demonstration sessions of 4th year pre-clerkship students who have had their anatomy learning through face-to-face SPRAD in year 2 (before the COVID-19 pandemic), online in year 3 (during the COVID-19 pandemic), and CALADS method in year 4. Descriptive statistics were used, and the level of significance was set at P<0.05. The survey exhibited high internal consistency (Cronbach's α=0.953). Validity of the survey was established through exploratory factor analysis. The preferred method for more than half of the students was the CALADS method. Face-to-face SPRAD came next and lastly came the online method. However, more students preferred the online method in comparison to face-to-face method for "learning radiological anatomy". There were no statistically significant differences between male and female students regarding any of the survey questions. CALADS method, as a hybrid, student-centered, interactive learning method of learning practical anatomy, was preferred by pre-clerkship students as a more effective method in understanding anatomy than face-to-face and online learning methods.

Gestures-enhanced anatomy teaching: A literature review of an educational strategy with promising outcomes.

PURPOSE: The educational use of gestures has resulted in positive outcomes in several fields. We performed a literature review to investigate the outcomes of the use of gestures to enhance the existing anatomy education methods. METHODS: PubMed, SCOPUS, ERIC and Cochrane databases were searched for papers with purpose to investigate the outcomes of the use of gestures (either seeing or performing them or both) as adjuncts to existing anatomy education methods. RESULTS: Six articles were included. Three studies comprised both seeing and performing gestures by the students, while the remaining three studies only comprised either seeing or performing gestures by the students. Most studies evaluated the acquisition of anatomical knowledge after the educational intervention and demonstrated that the addition of gestures resulted in significant benefit compared to control groups, while positive students' perceptions were recorded. It was not clarified whether seeing or performing gestures by the students leads to better educational outcomes. CONCLUSION: Gestures-enhanced anatomy education seems to be a promising teaching strategy, given that it has led to significantly increased acquisition of anatomical knowledge compared to no gestures-enhanced modalities. The addition of gestures to existing anatomy education modalities seems able to increase their potential without increasing their cost. Further research is needed to determine if seeing or performing gestures by the students is more effective.

Incorporation of team-based learning in the cadaveric anatomy laboratory: An overview.

PURPOSE: Team-based learning is a strategy which has resulted in positive outcomes concerning health professions education. We aimed to shed light on the role of this strategy when it is incorporated in the cadaveric anatomy laboratory. METHODS: We explored PubMed, SCOPUS, ERIC and Cochrane databases for articles with purpose to investigate the educational outcomes of the integration of team-based learning in the cadaveric anatomy laboratory. RESULTS: Six articles were eligible for inclusion. One of them assessed only participants' opinions about the educational intervention and five papers evaluated students' knowledge. Overall, the research showed significant improvement in students' examinations performance and significant superiority to control groups, as well as positive perceptions. There are limited data regarding the factors which may contribute to this success, but it seems that particularly the degree of teacher's involvement and competency needs to be further investigated. CONCLUSION: Anatomy educators may consider further adopting team-based learning to facilitate the achievement of the learning objectives of the cadaveric anatomy laboratory and increase the teaching potential of cadavers.

Time-lapse dissection videos: traditional practice in a new, digital format.

This research introduces an innovative series of time-lapse dissection videos that enable accelerated observation of the dissection process. Cadaveric dissection has consistently been described in the literature as a reliable method for enhancing student understanding and visualisation, however as a process it is expensive and extremely time-consuming, hence it is often inaccessible to learners. When active dissection is unavailable, prosections can be used to teach anatomy, however a considerable amount of spatial and structural information is lost during the dissection process. These time-lapse videos demonstrate dissection quickly and accurately and allow an irreversible process to be rewound and rewatched with flexibility. Results suggest that time-lapse offers a comprehensive and engaging view of the dissection process that students appreciate being able to observe within a concise timeframe. Written annotation, audio narration and colourful highlighting were essential inclusions following student feedback. These videos can provide instruction before dissection classes or can expose the dissection process to learners without access to cadaveric specimens. However, certain invaluable elements of practical dissection are rooted within constructivism and cannot be replicated by video. Time-lapse dissection videos should therefore be used to supplement and not replace active dissection.

Student-Perceived Value on the Use of Clay Modelling in Undergraduate Clinical Anatomy.

Clay modelling is increasingly used as an anatomy teaching method to supplement practical dissection sessions. The use of clay modelling is an active, tactile learning tool utilized to improve student engagement and enhance students' understanding of anatomical relationships in human anatomy. Furthermore, not only does clay modelling engage more senses in the learning process, but it was also found that there are educational advantages to the group interactions that are associated with the construction process to further collaborative learning.The aim of the study was to explore the effect of building anatomical clay models on students' awareness and understanding of their own thought processes as well as to explore whether clay modelling promoted collaborative learning. This cross-sectional study entailed the use of clay modelling and reflective practice to promote metacognition in third-year BSc students (n = 10), at the University of Stellenbosch's (SU) Division of Clinical Anatomy. The third-year BSc students were asked to build anatomical clay models (in groups), complete a reflective assignment and an evaluation form as part of their assessment of the Applied Anatomy module. The reflective assignment was based on Gibb's reflective cycle. The inclusion of such an assignment would trigger students to reflect upon their learning experiences and thus promote their metacognition.Ten (10) BSc students volunteered to take part in the study. A mixed method approach was followed; the reflective assignments were qualitatively analyzed, while the evaluation forms were quantitatively (statistically) analyzed. Data obtained from the online evaluation forms indicated agreeable responses confirming that the clay modelling was a valuable learning tool. However, the participants preferred cadaveric dissection instead of clay modelling to learn anatomy. Furthermore, three themes became prominent from the thematic analysis of the reflective assignments, namely, (1) Advantages of clay modelling, (2) Challenges of clay modelling, and (3) Suggestions for future practice.The research suggests that the inclusion of hands-on clay modelling in the undergraduate clinical anatomy is a valuable learning tool. The participants perceived that it enhanced their anatomical knowledge and improved collaborative learning.

The potential scope of a humanoid robot in anatomy education: a review of a unique proposal.

INTRODUCTION: Applications based on artificial intelligence and machine learning are becoming more popular in teaching learning. Advanced technologies have facilitated robots to carry out various human-like functions, which have navigated the interest of educators to discover the role of robots as potential teachers, instructors, or teaching assistants in education. METHODS: An extensive search for articles for humanoid robots and education either in the title or keywords was done utilizing PubMed, Google Scholar and Web of Science data sets. The tracking terms were artificial intelligence, education, medical education, anatomy, robots, humanoid robots, teaching, teaching assistant and tutor. RESULTS: The usage of artificial intelligence in the form of humanoid robots is quite common. However, literature citing its usage in medical education is rare. Humanoid robots as a teacher or teaching assistants are predominantly used in learning foreign languages. Primarily, a humanoid robot can discharge five functions as a potential teacher. CONCLUSION: Humanoid robots can effectively fulfil numerous educational goals in medicine since they can replicate human responses, work relentlessly regardless of students' repeated mistakes, be loaded with innovative teaching methodologies, and be upgraded with more current information. As a subject of medicine, anatomy is highly visual; therefore, constant endeavors have been initiated to develop technology-enhanced learning over the decades. Although artificial intelligence in humanoid robots has been successfully used in primary education and in learning a foreign language, its scope as an anatomy teacher or teaching assistant is a new and unique idea that needs exploration.

Modern and synchronized clinical anatomy teaching based on the BDIE method (board-digital dissection-imaging-evaluation).

PURPOSE: Anatomy has historically been taught via traditional medical school lectures and dissection. In many countries, practical or legal issues limit access to cadaveric dissection. New technologies are favored by students and could improve learning, complementing traditional teaching. METHODS: All students in second-year medicine at a single medical school were submitted to a novel anatomical course with digital tool exposure. We explored a new combined teaching method: a physical blackboard lesson synchronized with digital dissection, imaging and direct evaluation (BDIE). Synchronized dissection is broadcast live in the classroom and in partner medical schools. Following the course, students completed a short survey about their perception of this new anatomic clinical course. RESULTS: The survey included 183 students whom 178 completed the questionnaire, i.e., a 97% response rate. Ninety-nine percent of students thought this synchronized method useful to improve their understanding of anatomy and 90% stated it helped them retain this learning. CONCLUSION: This BDIE method, in conjunction with teaching guidelines and dissection, is highly appreciated by students who consider it helps them to acquire lasting knowledge.

Are extended reality technologies (ERTs) more effective than traditional anatomy education methods?

PURPOSE: Reviews and meta-analyses concerning the effectiveness of extended reality technologies (ERTs) (namely virtual, augmented, and mixed reality-VR, AR, and MR) in anatomy education (AE) have resulted in conflicting outcomes. The current review explores the existing evidence provided by reviews of AE literature regarding the effectiveness of ERTs after their comparison with traditional (either cadaveric or two-dimensional) anatomy teaching modalities and sheds light on the factors associated with the conflicting outcomes. METHODS: PubMed, SCOPUS, ERIC, and Cochrane databases were searched for review articles with the purpose to investigate the effectiveness of ERTs in AE. RESULTS: Nine (four systematic with or without meta-analysis and five non-systematic) reviews were included. A lack of robust evidence provided by those reviews was noted, mainly due to a remarkable confusion in the definition of each ERT, along with confusion when authors referred to traditional AE (TAE) methods. CONCLUSIONS: To clarify to what extent VR, AR, or MR can replace or supplement TAE methods, there is a primary need for addressing issues regarding the definition of each technology and determining which specific TAE methods are used as comparators.

Students' perspective on the interactive online anatomy labs during the COVID-19 pandemic.

PURPOSE: New training methods sprung up using communication technologies after the suspension imposed on Greek Universities due to restrictive measures against the COVID-19 pandemic. The current questionnaire-based study evaluates the efficacy and utility of the interactive online anatomy labs (ONALs) in assisting the assimilation of anatomy and substituting dissection labs during the pandemic. METHODS: ONALs consisting of video recorded demonstrations of dissected cadavers were developed so that real-time dialogue and interaction between tutor and students was feasible. First- and second-year medical students who were taught neuroanatomy and splanchnology and first-year dental students who were taught head and neck anatomy evaluated the ONALs. RESULTS: One hundred and sixty students participated. The 61 students (38.13%) attended the splanchnology, 58 (36.25%) the neuroanatomy, and 41 (25.63%) the head and neck anatomy course. 86.9% of the participants found the ONALs beneficial for their study. The 75.5% with previous experience of a "face-to-face" dissection replied that the ONALs cannot substitute satisfactorily "face-to-face" dissections. 63.8% replied positively to the ONALs maintenance after the pandemic. CONCLUSIONS: The study's novelty is based on the maintenance of the greater possible interaction between tutors and students during the ONALs, in contrast to the previously described usage of dissection educational videos in anatomy. Our findings reinforce the established statement that "a teaching dissection is an irreplaceable tool in anatomy education". However, the ONALs were well-received by the students and can be kept on as a supplementary teaching modality and can be proven quite useful in Medical Schools that lack cadavers.

Evaluation of the use of cadaveric computed tomography in anatomy education: An overview.

OBJECTIVE: We aimed to explore to what extent the literature supports that the use of cadaveric computed tomography can play an important role in anatomy education. MATERIALS AND METHODS: PubMed, SCOPUS, Education Resources Information Center and Cochrane Databases were searched for papers with purpose to explore the outcomes of the use of cadaveric computed tomography scans in anatomy education. The following data were obtained from each paper: authors, number of participants, type of study (comparative or not), level of outcome according to Kirkpatrick hierarchy, possible evaluation of statistical significance, acquisition of anatomical knowledge after the educational intervention and perceptions about the effectiveness of this intervention in anatomy learning. RESULTS: Seven articles were included. Four of them evaluated students' knowledge after the use of cadaveric computed tomography scans in anatomy education and three papers evaluated only students' perceptions. Generally, the outcomes, which mainly concerned students' perceptions, were positive, while it was showed that students' academic performance may also be improved. CONCLUSIONS: The outcomes of the use of cadaveric computed tomography scans in anatomy education encourage the implementation of this teaching modality in anatomy curricula. Further research, including comparative studies with evaluation of acquisition of students' knowledge, is needed to show if cadaveric computed tomography will be proved a remarkable supportive tool in anatomy educators' hands.

Outcomes of the implementation of game-based anatomy teaching approaches: An overview.

OBJECTIVE: We aimed to investigate to what extent the literature supports that game-based learning (gamification) could play a significant role in anatomy education. MATERIALS AND METHODS: PubMed, Education Resources Information Center and Cochrane Databases were searched for papers with purpose to investigate the educational outcomes of game-based anatomy learning. We extracted from each paper the number of participants, type of study (comparative or not), level of evidence according to Kirkpatrick hierarchy, possible evaluation of statistical significance, method which was implemented, academic performance of participants after the educational intervention, perceptions about the effectiveness of game-based approach and its impact on motivation to learn. RESULTS: Eight papers were included. Six of them were comparative, comprised assessment of students' examinations results and showed that those results were generally improved after exposure to game-based methods, in comparison with non-game-based ones. There is lack of evidence that the intensity of competition is correlated with the educational outcomes and that game-based approaches motivate students to a greater extent in comparison with other teaching methods. CONCLUSION: Game-based methods could obtain a remarkable supplemental role in the blended learning approach, which is applied by anatomy educators. Further research is needed to shed light on the characteristics of game-based methods which are more useful and should be adopted.

Canine Skull Digitalization and Three-Dimensional Printing as an Educational Tool for Anatomical Study.

This article aims to standardize 3D scanning and printing of dog skulls for educational use and evaluate the effectiveness of these anatomical printed models for a veterinary anatomy course. Skulls were selected for scanning and creating 3D-printed models through Fused Deposition Modeling using acrylonitrile-butadiene-styrene. After a lecture on skull anatomy, the 3D-printed and real skull models were introduced during the practical bone class to 140 students. A bone anatomy practical test was conducted after a month; it consisted in identifying previously marked anatomical structures of the skull bones. The students were divided into two groups for the exam; the first group of students took the test on the real skulls, whereas the second group of students took the test on 3D-printed skulls. The students' performance was evaluated using similar practical examination questions. At the end of the course, these students were asked to answer a brief questionnaire about their individual experiences. The results showed that the anatomical structures of the 3D-printed skulls were similar to the real skulls. There was no significant difference between the test scores of the students that did their test using the real skulls and those using 3D prints. In conclusion, it was possible to construct a dynamic and printed digital 3D collection for studies of the comparative anatomy of canine skull species from real skulls, suggesting that 3D-digitalized and-printed skulls can be used as tools in veterinary anatomy teaching.

Body Painting Plus: Art-Based Activities to Improve Visualisation in Clinical Education Settings.

Art-based activities are increasingly being regarded as an accessible and engaging way to understand the human body and its processes. Such activities include body painting (both regular and ultraviolet [UV]), clay and materials-based modelling and drawing-focused activities. Integrating art-based approaches into curricula can offer many benefits and are often cost-effective ways to engage students, and improve on clinical acumen and visual understanding of the body. In this chapter, we will introduce various art-based visualisation methods, suggested uses for their integration into curricula, as well as the associated pros and cons of each, in turn.
