The effects of supplemental instruction derived from peer leaders on student outcomes in undergraduate human anatomy.

Supplemental instruction (SI) confers student success, as represented by grades, knowledge retention, and student engagement. However, studies often report professional, not undergraduate, program findings. To measure these effects, students studying human anatomy at a university in Ontario, Canada, attended structured (peer-assisted) or unstructured (nonpeer-assisted) SI sessions and completed a pre-/post-survey. Fifty-eight learners (39 systems (SYS) and 19 musculoskeletal (MSK) anatomy) completed both surveys and had responses analyzed. Both cohorts, maintained initial perceptions across pre-/post-analyses (MSK p = 0.1376 and SYS p = 0.3521). Resource usage was similar across both cohorts with discrepancies in skeletal model and textbook use. No MSK learner ranked any lab resources as "not at all useful." MSK learners felt more prepared to write a graded assessment (p = 0.0269), whereas SYS learners did not (p = 0.0680). Stratification of learners in MSK and SYS revealed learners spending between 30 and 60 min in SI sessions during the study period had the highest grades compared to students who spent less than 30 (p = 0.0286) or more than 60 (p = 0.0286) min attending SI sessions, respectively. Most learners in MSK (89.4%) and SYS (66%) concluded that they preferred structured over unstructured SI. Sentiment/thematic analysis using a generative AI-driven large language model revealed learners held positive perceptions of SI, emphasizing structured learning, resources, personalized learning, and support offered as the most prevalent themes surrounding SI. Ultimately, this study provides evidence that supports SI for improving student outcomes related to perceived preparedness for completing assessments and preferred teaching/learning styles in undergraduate human anatomy.

The effect of simulation of sectional human anatomy using ultrasound on students' learning outcomes and satisfaction in echocardiography education: a pilot randomized controlled trial.

BACKGROUND: Effective teaching methods are needed to improve students' abilities in hand-eye coordination and understanding of cardiac anatomy in echocardiography education. Simulation devices have emerged as innovative teaching tools and exhibited distinctive advantages due to their ability to provide vivid and visual learning experiences. This study aimed to investigate the effect of simulation of sectional human anatomy using ultrasound on students' learning outcomes and satisfaction in echocardiography education. METHODS: The study included 18 first-year clinical medical students with no prior echocardiography training. After randomization, they underwent a pre-test to assess basic knowledge. Following this, the students were divided into two groups: traditional teaching (traditional group) and simulation of sectional human anatomy using ultrasound (digital group). Each group received 60 min of instruction. Post-tests were assigned to students at two different time points: immediately after the lecture, and one week later (referred to as post-tests 1, and 2). In addition, anonymous questionnaires were distributed to students after class to investigate their satisfaction with teaching. RESULTS: Both groups showed significant improvement in their scores on post-test 1 compared to pre-test (traditional group: from 33.1 ± 8.8 to 48.1 ± 13.1, P = 0.034 vs. digital group: from 35.0 ± 6.7 to 58.0 ± 13.2, P = 0.008). However, there were no significant differences between the two groups in several post-test comparisons. Student satisfaction ratings revealed that the digital group experienced significantly greater satisfaction in areas such as subject interest, teaching style, course alignment, and interaction compared to the traditional group. Additionally, 80% of the digital group strongly endorsed the use of simulation of sectional human anatomy using ultrasound for echocardiography teaching, highlighting its effectiveness. CONCLUSIONS: Simulation of sectional human anatomy using ultrasound may improve students' understanding of echocardiography and satisfaction with the course. Our study provides evidence supporting the use of simulation teaching devices in medical education. Further research is needed to explore the long-term impact of this teaching method on students' learning outcomes and its integration into the medical curriculum.

Examen Práctico Objetivo Estructurado como metodología de evaluación en la asignatura de Anatomía Humana: Experiencia de una Implementación Piloto

Aprendizajes en anatomía humana tradicionalmente han sido evaluados a través del reconocimiento de estructuras anatómicas. A pesar de su popularidad, pueden tener un componente subjetivo y memorístico. El Examen Práctico Objetivo Estructurado (EPOE) se ha presentado como una manera más global de evaluación. El objetivo de este estudio fue evidenciar el efecto en el rendimiento académico tras la implementación del EPOE en pasos prácticos. En el estudio 2312 estudiantes fueron divididos: Metodología Tradicional (n=1155) y Metodología EPOE (n=1157). A su vez, los estudiantes fueron identificados según carrera: Enfermería (n=1182); Fonoaudiología (n=185); Kinesiología (n=514) y Terapia Ocupacional (n=431). Se mantuvieron las condiciones de la asignatura en ambos grupos con tres evaluaciones prácticas. Se analizaron las calificaciones obtenidas. Evaluaciones 1 y 2 no presentaron diferencias entre grupos. Evaluación 3, que evaluó sistema nervioso, mostró disminución significativa de 0,5 puntos en el grupo EPOE. El factor tipo de metodología resultó ser significativo en evaluación 3 (p < 0,001; h2p = 0,029) y promedio de las 3 evaluaciones (p < 0,029; h2p = 0,002). El factor carrera resultó ser significativo para las tres evaluaciones. La interacción de ambos factores no mostró significancia estadística. El análisis post hoc mostró diferencias significativas entre estudiantes de Enfermería con las demás carreras, ya que obtuvieron mejores calificaciones en todas las evaluaciones (p < 0,05). Metodología EPOE no produjo drásticos cambios en el rendimiento académico de los estudiantes y tiene un amplio potencial de desarrollo por su naturaleza de evaluación integral no invasiva ni traumática. Se debe considerar la naturaleza de los contenidos en el diseño de la metodología de enseñanza-aprendizaje y en la metodología de evaluación, alineando a nivel microcurricular estos aspectos fundamentales de la formación de nuevos profesionales de la salud.

SUMMARY: Learning in human anatomy has traditionally been assessed by recognizing anatomical structures. Despite their popularity, they can have a subjective component. The Objective Structured Practical Examination (EPOE) has been presented as a more global way of assessment. The aim of this study was to demonstrate the effect on academic performance after the implementation of the EPOE in practical activities. In this study 2312 students were divided into Traditional Methodology (n=1155) and EPOE Methodology (n=1157). In turn, students were identified according to career: Nursing (n=1182), Speech Therapy (n=185), Physical Therapy (n=514), and Occupational Therapy (n=431). Subject conditions were maintained in both groups with three practical evaluations. The grades obtained were analyzed. Assessments 1 and 2 showed no differences between groups. Evaluation 3, which evaluated the nervous system, showed a significant decrease of 0.5 points in the EPOE group. The type of methodology factor was significant in evaluation 3 (p < 0.001; ?2p = 0.029) and the average of 3 evaluations (p < 0.029; ?2p = 0.002). The career factor was significant for all three evaluations. The interaction of both factors did not show statistical significance. The post hoc analysis showed significant differences between nursing students and the other careers since they obtained better scores in all evaluations (p < 0.05). EPOE methodology did not produce drastic changes in students' academic performance and had a broad potential for development due to its non-invasive and non-traumatic comprehensive assessment nature. The nature of the contents should be considered in the design of the teaching-learning methodology and the evaluation methodology, aligning at the micro-curricular level with these fundamental aspects of training new health professionals.

Assessing the Utilization and Effectiveness of YouTube in Anatomy Education Among Medical Students: A Survey-Based Study.

Introduction Learning methodologies, particularly in medical education, are evolving with the integration of internet-based technologies into daily life. As a platform, YouTube has become a significant tool for studying human anatomy among medical students. This study aims to assess the utilization of YouTube in learning human anatomy, the types of audio-visual materials used, and the platform's perceived effectiveness in understanding and memorizing anatomical information. Methods A cross-sectional questionnaire study was conducted among 200 medical students at a medical college over one year, of whom 195 completed the questionnaire and were included. The questionnaire addressed general YouTube usage, specific usage for medical studies and human anatomy, types of audio-visual materials used, and the perceived effectiveness of YouTube in understanding and memorizing anatomical information. Data were analyzed using IBM SPSS Statistics for Windows, Version 25.0 (IBM Corp., Armonk, NY) for Pearson's chi-square test to determine statistical differences based on gender and year of study. Results The study cohort comprised 195 medical students (average age: 19.8±1.1 years), 62.6% females and 37.4% males. YouTube emerged as extensively utilized, with 94.5% of males and 96.7% of females reporting general usage and 91.8% of males and 89.3% of females utilizing it for medical studies. For human anatomy learning, 93.2% of males and 89.3% of females relied on YouTube. Among the audio-visual materials, PowerPoint presentations were most prevalent, favored by 46.5% of males and 41.8% of females. Regarding effectiveness, 82.1% of males and 83.7% of females affirmed YouTube's enhancement of anatomical understanding, with 89% of males and 85.3% of females acknowledging its aid in memorization. Additionally, 90.4% of males and 87.3% of females recommended YouTube as an anatomy learning tool. Despite observed gender-based preferences for specific content types, no statistically significant differences were discerned in YouTube's usage and perception across genders. Conclusions YouTube is a widely used and effective tool for the study of human anatomy among medical students, facilitating the understanding and memorization of anatomical information. While cadaver dissection remains an irreplaceable part of medical education, the addition of YouTube as a learning resource can enhance the educational experience. Future research should focus on the in-depth exploration of content satisfaction and the potential role of YouTube in the broader anatomy curriculum.

3D visualization technology for Learning human anatomy among medical students and residents: a meta- and regression analysis.

BACKGROUND: 3D visualization technology applies computers and other devices to create a realistic virtual world for individuals with various sensory experiences such as 3D vision, touch, and smell to gain a more effective understanding of the relationships between real spatial structures and organizations. The purpose of this study was to comprehensively evaluate the effectiveness of 3D visualization technology in human anatomy teaching/training and explore the potential factors that affect the training effects to better guide the teaching of classroom/laboratory anatomy. METHODS: We conducted a meta-analysis of randomized controlled studies on teaching human anatomy using 3D visualization technology. We extensively searched three authoritative databases, PubMed, Web of Science, and Embase; the main outcomes were the participants' test scores and satisfaction, while the secondary outcomes were time consumption and enjoyment. Heterogeneity by I² was statistically determined because I²> 50%; therefore, a random-effects model was employed, using data processing software such as RevMan, Stata, and VOSviewer to process data, apply standardized mean difference and 95% confidence interval, and subgroup analysis to evaluate test results, and then conduct research through sensitivity analysis and meta-regression analysis. RESULTS: Thirty-nine randomized controlled trials (2,959 participants) were screened and included in this study. The system analysis of the main results showed that compared with other methods, including data from all regions 3D visualization technology moderately improved test scores as well as satisfaction and enjoyment; however, the time that students took to complete the test was not significantly reduced. Meta-regression analysis also showed that regional factorsaffected test scores, whereas other factors had no significant impact. When the literature from China was excluded, the satisfaction and happiness of the 3D virtual-reality group were statistically significant compared to those of the traditional group; however, the test results and time consumption were not statistically significant. CONCLUSION: 3D visualization technology is an effective way to improve learners' satisfaction with and enjoyment of human anatomical learning, but it cannot reduce the time required for testers to complete the test. 3D visualization technology may struggle to improve the testers' scores. The literature test results from China are more prone to positive results and affected by regional bias.

Contribution of Anatomy in Forensic Age Evaluation: A Systematic Review.

The field of forensic anthropology is characterised by its ongoing development and growth. Forensic anatomy is a burgeoning discipline that focuses on the analysis and identification of both preserved and unpreserved human body parts, both in deceased individuals and the living. This subject plays a crucial role in establishing the four key factors of forensic anthropology, namely sex, age, race, and height. The objective of this research endeavour was to evaluate the significance of anatomical information in the process of forensic age estimation. The researchers established the inclusion criteria in accordance with the globally recognised Population, Intervention, Comparison, Outcome (PICOS) framework, as advised by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The research included many methodologies in order to ascertain the age. Upon conducting a comprehensive review of the existing literature pertaining to anatomical knowledge in the field of forensic age estimate, we have identified many notable applications. These include the utilisation of various anatomical features such as the dental pulp chamber, fingerprints, acetabulum, sternal end of the fourth rib, as well as hand and wrist bones for the purpose of age estimation. It is important for anatomists and other forensic scientists to engage in collaborative efforts to facilitate the exchange of ideas and ensure thorough investigations. This cooperation is particularly crucial in areas where anatomical sciences play a significant role in forensic science and investigation. Nevertheless, in order to mitigate the potential for estimating error, it is still advisable to use a multi-factorial evaluation approach that involves examining many body areas.

Frequency and characterization of the accessory heads of the biceps brachii: A multicentric cadaveric study.

PURPOSE: The biceps brachii muscle (BBM) is a large and thick muscle on the ventral portion of the upper arm. The scientific literature reports the existence of extra heads. OBJECTIVE: The present work investigated the frequency of occurrence of BBM accessory head(s) in four different Anatomy Laboratories at universities in Northeast Brazil. MATERIAL AND METHODS: Once the upper limbs with an anatomical variation of the BBM heads were identified, the accessory head was evaluated for morphometric characterization (the length, width, and thickness). RESULTS: The sample consisted of 249 upper limbs and the outcomes were 26 members with BBM accessory heads (10.44% of the total sample). Among the 26 members studied was found a single accessory head in 22 (84.62%), two accessory heads in 3 (11.54%), and three accessory heads in 1 (3.85%). BBMs with one, two, and three accessory heads were found, with different origins. The average length, width, and thickness of these accessory heads were 169.39mm, 10.25mm, and 3.39mm, respectively. CONCLUSION: The frequency of BBM accessory heads in a population of northeastern Brazil in this cadaveric study was 10.44%.

Dissecting human anatomy learning process through anatomical education with augmented reality: AEducAR 2.0, an updated interdisciplinary study.

Anatomical education is pivotal for medical students, and innovative technologies like augmented reality (AR) are transforming the field. This study aimed to enhance the interactive features of the AEducAR prototype, an AR tool developed by the University of Bologna, and explore its impact on human anatomy learning process in 130 second-year medical students at the International School of Medicine and Surgery of the University of Bologna. An interdisciplinary team of anatomists, maxillofacial surgeons, biomedical engineers, and educational scientists collaborated to ensure a comprehensive understanding of the study's objectives. Students used the updated version of AEducAR, named AEducAR 2.0, to study three anatomical topics, specifically the orbit zone, facial bones, and mimic muscles. AEducAR 2.0 offered two learning activities: one explorative and one interactive. Following each activity, students took a test to assess learning outcomes. Students also completed an anonymous questionnaire to provide background information and offer their perceptions of the activity. Additionally, 10 students participated in interviews for further insights. The results demonstrated that AEducAR 2.0 effectively facilitated learning and students' engagement. Students totalized high scores in both quizzes and declared to have appreciated the interactive features that were implemented. Moreover, interviews shed light on the interesting topic of blended learning. In particular, the present study suggests that incorporating AR into medical education alongside traditional methods might prove advantageous for students' academic and future professional endeavors. In this light, this study contributes to the growing research emphasizing the potential role of AR in shaping the future of medical education.

The effect of pre-body donor quizzes on student performance in a hybrid anatomy course.

Learning human anatomy is essential for Doctor of Physical Therapy (DPT) education. Body donors are traditionally utilized to understand content, but in a hybrid learning environment, students have limited time to use body donors. To improve body donor access and learning, we created online synchronous pre-body donor activities. The impact of these online strategies on students' subsequent exams and final grade were investigated in a non-randomized, observational study. These activities were hypothesized to positively influence students' anatomy performance. In a 16-week semester, DPT students (case [n = 91], control [n = 22]) participated in a hybrid program of asynchronous/synchronous online learning and two in-person immersions. Measures included student course grades and teaching surveys. Spearman's rho correlations analyzed the relationship between four pre-body donor quizzes to body donor exams, written exams, and final course grade. Mann-Whitney U tests assessed differences in grades between cohorts. A linear regression model examined the influence of pre-body donor quizzing on exams/final grades. Correlation tests revealed a strong relationship between the average pre-body donor quiz score and both the first written exam and final course grade (p = 0.0001). The case group achieved significantly higher scores than the control group on the first in-person body donor exam (p = 0.011), the second written exam (p = 0.0001), and the final grade (p = 0.004). The pre-body donor quizzes predicted performance on the subsequent in-person body donor exams, written exams, and the final grade. Implementation of online pre-body donor learning activities was associated with increased academic performance among hybrid DPT students and may aid in learning anatomy concepts for clinical practice.

Exploring reliable photogrammetry techniques for 3D modeling in anatomical research and education.

In anatomical research and education, three-dimensional visualization of anatomical structures is crucial for understanding spatial relationships in diagnostics, surgical planning, and teaching. While computed tomography (CT) and magnetic resonance imaging (MRI) offer valuable insights, they are often expensive and require specialized resources. This study explores photogrammetry as an affordable and accessible approach for 3D modeling in anatomical contexts. Two photogrammetry methods were compared: conventional open-source software (Colmap) and Apple's RealityKit Object Capture. Human C3 vertebrae were imaged with a 24 MP camera, with and without a cross-polarization filter. Reconstruction times, vertex distances, surface area, and volume measurements were compared to CT scans. Results revealed that the Object Capture method surpassed the conventional approach in reconstruction speed and user-friendliness. Both methods exhibited similar vertex distance from reference mesh and volume measurements, although the conventional approach produced larger surface areas compared to CT-based models. Cross-polarization filters eliminated the need for pre-processing and improved outcomes in challenging lighting conditions. This study demonstrates that photogrammetry, especially Object Capture, as a reliable and time-efficient tool for 3D modeling in anatomical research and education. It offers accessible alternatives to traditional techniques with advantages in texture mapping. While further validation of various anatomical structures is required, the accessibility and cost-effectiveness of photogrammetry make it a valuable asset for the field. In summary, photogrammetry would have the potential to revolutionize anatomical research and education by providing cost-effective, accessible, and accurate 3D modeling. The study underscores the promise of advancing anatomical research and education through the integration of photogrammetry with ongoing improvements in user-friendliness and accessibility.

Acquisition of cadavers for anatomy education and research in Malawi.

BACKGROUND: The use of human cadaveric dissection forms an essential part of teaching anatomy to health sciences students in Malawi. Despite worldwide struggles in acquiring sufficient human cadavers for anatomy education, the current recommendations on the best anatomy practices require the use of cadavers exclusively from the body donation programs. The current study aims to describe the sources of cadaveric bodies used for anatomy education in the Malawian context and reflect on the feasibility of using cadavers from the body donation program only. METHODS: A retrospective audit of the cadaveric records for the 2006-2022 academic years at the Kamuzu University of Health Sciences was done. The perceived challenges when sourcing the cadavers were identified and described based on the authors experiences in Malawi. RESULTS: The majority (97.3%) of the cadavers used between 2006 and 2022 were unclaimed bodies. The mean age of the cadavers was 45 years. Most (95.6%) of the unclaimed bodies were males. All the unclaimed bodies were sourced from hospitals. The body donation program in Malawi was patronized by populations of European descent only. Strongly held sociocultural and religious beliefs as well as economic reasons were perceived as significant barriers to acquiring cadavers of the indigenous Malawians through the body donation program. CONCLUSION: Cadavers for anatomy education in Malawi are mainly from unclaimed bodies, similar to other African countries. The authors support the transition from using "mostly unclaimed bodies (and, less often, body donation)" to using "mostly body donation (and, less often, unclaimed bodies)" through awareness campaigns that are targeted to address the prevailing challenges.

Learning functional human anatomy with a new interactive three-dimensional digital tool.

Human anatomy requires understanding spatial relationships among anatomical structures and is often perceived as difficult to learn by students. To overcome this concern, several digital tools exist with some strengths and limitations among which the lack of interactivity especially for complex functional anatomy learning. In this way, a new interactive three-dimensional tool called Antepulsio was designed. Antepulsio was assessed by comparing three groups of first year kinesiology students to test whether it is likely to favor functional anatomy learning during three training sessions spread over a week. The experiment was conducted during a real academic course. Laterality judgment, 3D spatial abilities and working memory abilities from all participants were previously collected to create three homogeneous groups: the active group (n = 17, 17.76 ± 0.56 years) interacted with Antepulsio, the passive group (n = 18, 17.89 ± 0.83 years) watched videos of Antepulsio while the control group (n = 15, 18.07 ± 0.80 years) performed a neutral activity unrelated to anatomy. Anatomy knowledge was also assessed during pretest, posttest, and retention test (8 weeks after the posttest). The most significant outcome of this study revealed that in case of better working visual memory, the active group outperformed the passive group between pretest and retention test (p < 0.01). In other words, Antepulsio tool is efficient only for students with high visuospatial working memory. These selective benefits of Antepulsio are discussed in terms of cognitive load, training duration and the necessary period of familiarization with the tool.

Exploring the uncharted: Missing anatomical names in the Terminologia Anatomica.

Effective communication and precise navigation within the intricacies of the human body rely on robust anatomical terminology. Since its creation by the Federative Committee on Anatomical Terminology (FCAT), the Terminologia Anatomica (TA 1998) has consistently served as the benchmark in the field. However, the constant advancement of anatomical knowledge requires regular revisions, updates, and enhancements of anatomical nomenclature to accommodate the latest scientific discoveries. The recent adoption of the second edition of Terminologia Anatomica (TA 2019) by the International Federation of Associations of Anatomists (IFAA) has drawn attention to certain notable omissions. Despite over a century of dedicated work establishing standard anatomical terminology, specific widely recognized gross anatomical structures are still absent from the official listing in the Terminologia Anatomica. There is, however, a consensus that the inclusion of names for trivial or variably present structures should be avoided. Accordingly, this article focuses on a thoughtfully selected group of anatomical structures, which are so important that they are routinely discussed during anatomy courses, despite their exclusion from the official lists of anatomical terms. These basic structures hold fundamental importance for both anatomy education and clinical practice. Consequently, their appropriate nomenclature warrants consideration for inclusion in future editions of TA.

Show them what they can't see! An evaluation of the use of customized 3D printed models in head and neck anatomy.

Difficulty in visualizing anatomical structures has been identified as a challenge in anatomy learning and the emergence of three-dimensional printed models (3DPMs) offers a potential solution. This study evaluated the effectiveness of 3DPMs for learning the arterial supply of the head and neck region. One hundred eighty-four undergraduate medical students were randomly assigned to one of four learning modalities including wet specimen, digital model, 3DPM, and textbook image. Posttest scores indicated that all four modalities supported participants' knowledge acquisition, most significantly in the wet specimen group. While the participants rated 3DPMs lower for helping correct identification of structures than wet specimens, they praised 3DPMs for their ability to demonstrate topographical relationships between the arterial supply and adjacent structures. The data further suggested that the biggest limitation of the 3DPMs was their simplicity, thus making it more difficult for users to recognize the equivalent structures on the wet specimens. It was concluded that future designs of 3DPMs will need to consider the balance between the ease of visualization of anatomical structures and the degree of complexity required for successful transfer of learning. Overall, this study presented some conflicting evidence of the favorable outcomes of 3DPMs reported in other similar studies. While effective for anatomy learning as a standalone modality, educators must identify the position 3DPM models hold relative to other modalities in the continuum of undergraduate anatomy education in order to maximize their advantages for students.

Incidence of the tensor of the vastus intermedius: A cadaveric study.

INTRODUCTION: The quadriceps femoris muscle is present in the anterior region of the thigh and is classically described as a muscle with four heads: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. A few years ago, a "fifth head" was described and named the tensor of the vastus intermedius (TVI). The TVI belly is in line with the belly of the vastus lateralis, and its aponeurosis imposes considerable tension on the vastus intermedius, medializing its action, to play a significant role in knee extension. OBJECTIVE: To perform a study of the TVI incidence in a Brazilian population and describe its variations. MATERIAL AND METHODS: We dissected lower limbs from cadavers previously fixed in 10% formaldehyde, belonging to the Laboratory of Anatomy of the Department of Morphology of the Biosciences Center of the Federal University of Rio Grande do Norte. RESULTS: Eighty-one lower limbs were analyzed with only 33 (40.74%) of them presenting TVI. All four types of TVI described by the literature were present in our sample with the following distribution: type 1 with 15.15%; type 2 with 9.1%; type 3 with 33.33%; type 4 with 42.42%. DISCUSSION: Although the literature points to the TVI as a normal belly of the quadriceps, making it a "quinticeps", our analysis points to the TVI as a variation and probably a matter of regionality. However, the presence of TVI is not a rare case and cannot be disregarded, which makes this study important for anatomists, physiotherapists, physicians, and surgeons.

The combined effects of an anatomy program integrating drawing and gamification on basic psychological needs satisfaction among sport sciences students: Results of a natural experiment.

According to self-determination theory, the need for competence, autonomy, and relatedness has been associated with intrinsic motivation. Fulfilling basic psychological needs can lead to better learning, academic performance, and well-being. In this study, an anatomy program integrated gamification and drawing methods to explore their influence on basic psychological needs satisfaction and potential learning implications. Basic psychological needs outcomes of sport sciences students were compared to test the effects of the Observe-Reflect-Draw-Edit-Repeat (ORDER) method and gamification (experimental condition) versus a non-ORDER and non-gamified program (control condition). These two different 30-h (7-week) anatomy education programs were implemented at two Spanish public universities with 116 first-year sport sciences students. Pre and post-treatment measurements were collected using the Basic Psychological Needs Satisfaction Scale. Statistical analyses included independent samples t-tests, ANCOVAs, and factorial repeated measures ANOVAs 2 × 2 (time × treatment). The gamified ORDER program achieved higher satisfaction scores in basic psychological needs compared to the control group (t = 2.98, p = 0.004, d = 0.54). Additionally, an interaction effect between time and treatment was observed (p = 0.042, η p 2 = 0.038). Treatment and interaction effects were observed for 'autonomy' (p = 0.003, η p 2 = 0.074) and 'competence' satisfaction (p = 0.048, η p 2 = 0.035). A time effect was found for 'relatedness' in the control group, but no significant treatment or interaction effects were identified. The causes of these effects are debated in the study, as well as the limitations. These findings support the notion that students' basic psychological needs are better satisfied in anatomy education with the implementation of this multimethod educational intervention based on ORDER and gamification.

Introduction: The new generations of students, such as the current generation Z or digital natives, have provoked the need to implement new teaching methodologies where students are active and participative subjects in their own learning process. Among these methodologies, the use of game-based learning can be considered an alternative to reinforce the classic ‘master class’ in university teaching. Subjects and methods: Use of game-based learning (serious games), in students enrolled in the subject of Human Anatomy I (Locomotor System), first year of the Degree of Medicine at the Universidad de Zaragoza. Results: The use of this methodology has been evaluated, by means of a voluntary evaluation survey, in a very positive way, emphasizing the effect on motivation, participation and integration of theoretical and practical contents. Conclusion: Game-based learning should be considered as a powerful alternative that improves motivation, participation and content integration in the higher education classroom.(AU)
