RESUMO

The development of CRISPR-based barcoding methods creates an exciting opportunity to understand cellular phylogenies. We present a compact, tunable, high-capacity Cas12a barcoding system called dual acting inverted site array (DAISY). We combined high-throughput screening and machine learning to predict and optimize the 60-bp DAISY barcode sequences. After optimization, top-performing barcodes had ∼10-fold increased capacity relative to the best random-screened designs and performed reliably across diverse cell types. DAISY barcode arrays generated ∼12 bits of entropy and ∼66,000 unique barcodes. Thus, DAISY barcodes-at a fraction of the size of Cas9 barcodes-achieved high-capacity barcoding. We coupled DAISY barcoding with single-cell RNA-seq to recover lineages and gene expression profiles from ∼47,000 human melanoma cells. A single DAISY barcode recovered up to ∼700 lineages from one parental cell. This analysis revealed heritable single-cell gene expression and potential epigenetic modulation of memory gene transcription. Overall, Cas12a DAISY barcoding is an efficient tool for investigating cell-state dynamics.

RESUMO

In the United States, the onset of COVID-19 triggered a nationwide lockdown, which forced many universities to move their primary assessments from invigilated in-person exams to unproctored online exams. This abrupt change occurred midway through the Spring 2020 semester, providing an unprecedented opportunity to investigate whether online exams can provide meaningful assessments of learning relative to in-person exams on a per-student basis. Here, we present data from nearly 2,000 students across 18 courses at a large Midwestern University. Using a meta-analytic approach in which we treated each course as a separate study, we showed that online exams produced scores that highly resembled those from in-person exams at an individual level despite the online exams being unproctored-as demonstrated by a robust correlation between online and in-person exam scores. Moreover, our data showed that cheating was either not widespread or ineffective at boosting scores, and the strong assessment value of online exams was observed regardless of the type of questions asked on the exam, the course level, academic discipline, or class size. We conclude that online exams, even when unproctored, are a viable assessment tool.

RESUMO

The analysis of streaming time-to-event cohorts has garnered significant research attention. Most existing methods require observed cohorts from a study sequence to be independent and identically sampled from a common model. This assumption may be easily violated in practice. Our methodology operates within the framework of online data updating, where risk estimates for each cohort of interest are continuously refreshed using the latest observations and historical summary statistics. At each streaming stage, we introduce parameters to quantify the potential discrepancy between batch-specific effects from adjacent cohorts. We then employ penalized estimation techniques to identify nonzero discrepancy parameters, allowing us to adaptively adjust risk estimates based on current data and historical trends. We illustrate our proposed method through extensive empirical simulations and a lung cancer data analysis.

RESUMO

PURPOSE: Considerable debate centered on the impact of school closures and shifts to virtual learning on adolescent mental health during the COVID-19 pandemic. We evaluated whether mental health changes differed by school learning modes during the pandemic response among Canadian adolescents and whether associations varied by gender and perceived home life. METHODS: We used prospective survey data from 7270 adolescents attending 41 Canadian secondary schools. Conditional change linear mixed effects models were used to examine learning mode (virtual optional, virtual mandated, in-person, and blended) as a predictor of change in mental health scores (depression [Centre for Epidemiologic Studies - Depression], anxiety [Generalized Anxiety Disorder-7], and psychosocial well-being [Flourishing scale]), adjusting for baseline mental health and covariates. Gender and home life happiness were tested as moderators. Least square means were calculated across interaction groups. RESULTS: Students learning in a blended learning mode had greater anxiety increases relative to their peers in other learning modes. Females learning fully in-person and males learning virtually when optional reported less of an increase in depression scores relative to their gender counterparts in other learning modes. Learning virtually when optional was associated with greater declines in psychosocial well-being in students without happy home lives relative to other learning modes. CONCLUSION: Findings demonstrate the importance of considering gender and home environments as determinants of mental health over the pandemic response and when considering alternative learning modes. Further research is advised before implementing virtual and blended learning modes. Potential risks and benefits must be weighed in the context of a pandemic.

RESUMO

BACKGROUND: Only one out of every ten Nigerian adults with hypertension has their blood pressure controlled. Health worker training is essential to improve hypertension diagnosis and treatment. In-person training has limitations that mobile, on-demand training might address. This pilot study evaluated a self-paced, case-based, mobile-optimized online training to diagnose and manage hypertension for Nigerian health workers. METHODS: Twelve hypertension training modules were developed, based on World Health Organization and Nigerian guidelines. After review by local academic and government partners, the course was piloted by Nigerian health workers at government-owned primary health centers. Primary care physician, nurse, and community health worker participants completed the course on their own smartphones. Before and after the course, hypertension knowledge was evaluated with multiple-choice questions. Learners provided feedback by responding to questions on a Likert scale. RESULTS: Out of 748 users who sampled the course, 574 enrolled, of whom 431 (75%) completed the course. The average pre-test score of completers was 65.4%, which increased to 78.2% on the post-test (P < 0.001, paired t-test). Health workers who were not part of existing hypertension control programs had lower pre-test scores and larger score gains. Most participants (96.1%) agreed that the training was applicable to their work, and nearly all (99.8%) agreed that they enjoyed the training. CONCLUSIONS: An on-demand mobile digital hypertension training increases knowledge of hypertension management among Nigerian health workers. If offered at scale, such courses can be a tool to build health workforce capacity through initial and refresher training on current clinical guidelines in hypertension and other chronic diseases in Nigeria as well as other countries.

RESUMO

The COVID-19 pandemic has changed peoples' lives in unexpected ways, especially how they allocate their time between work and other activities. Demand for online learning has surged during a period of mass layoffs and transition to remote work and schooling. Can this uptake in online learning help close longstanding skills gaps in the US workforce in a sustainable and equitable manner? We answer this question by analyzing individual engagement data of DataCamp users between October 2019 and September 2020 (n = 277,425). Exploiting the staggered adoption of actions to mitigate the spread of COVID-19 across states, we identify the causal effect at the neighborhood level. The adoption of nonessential business closures led to a 38% increase in new users and a 6% increase in engagement among existing users. We find that these increases are proportional across higher- and lower-income neighborhoods and neighborhoods with a high or low share of Black residents. This demonstrates the potential for online platforms to democratize access to knowledge and skills that are in high demand, which supports job security and facilitates social mobility.

RESUMO

Online learning in Health Professions Education (HPE) has been evolving over decades, but COVID-19 changed its use abruptly. Technology allowed necessary HPE during COVID-19, but also demonstrated that many HP educators and learners had little knowledge and experience of these complex sociotechnical environments. Due to the educational benefits and flexibility that technology can afford, many higher education experts agree that online learning will continue and evolve long after COVID-19. As HP educators stand at the crossroads of technology integration, it is important that we examine the evidence, theories, advantages/disadvantages, and pedagogically informed design of online learning. This Guide will provide foundational concepts and practical strategies to support HPE educators and institutions toward advancing pedagogically informed use of online HPE. This Guide consists of two parts. The first part will provide an overview of evidence, theories, formats, and educational design in online learning, including contemporary issues and considerations such as learner engagement, faculty development, inclusivity, accessibility, copyright, and privacy. The second part (to be published as a separate Guide) focuses on specific technology tool types with practical examples for implementation and integration of the concepts discussed in Guide 1, and will include digital scholarship, learning analytics, and emerging technologies. In sum, both guides should be read together, as Guide 1 provides the foundation required for the practical application of technology showcased in Guide 2.Please refer to the video abstract for Part 1 of this Guide at https://bit.ly/AMEEGuideOnlineLearning.

RESUMO

What was the educational challenge?Medical student abuse within work-integrated learning (WIL) is well-reported, with negative consequences for wellbeing, motivation, and learning. Conversely, workplace dignity, described as respecting the worth of others and self, has positive impacts on wellbeing, learning, and relationships for WIL students and supervisors. Stakeholders often struggle to articulate what workplace dignity means, and can downplay or do nothing in the face of WIL indignities.What was the solution and how was this implemented?We created an innovative research-informed online learning resource about WIL dignity to improve stakeholders' understandings and help them get the best from WIL placements ensuring these are dignified, safe, and educationally productive. The resource included three topics: (a) workplace dignity and why it matters; (b) upholding dignity; and (c) strengthening dignity.What lessons were learned?We conducted a pilot qualitative evaluation involving 13 semi-structured interviews with students and supervisors to elicit their views and experiences of the resource. Our key findings across three overarching categories were: (1) perceived benefits (motivations to complete the resource; content of the resource; online pedagogies); (2) potential applications of learning (reinforcing existing knowledge; developing new knowledge; promoting reflection; changing workplace practices); and (3) suggested improvements (barriers to resource use; resource content; online pedagogies; timing of resource implementation; embedding the resource in broader learning).What are the next steps?Although we identified numerous perceived benefits, and applications of learning, the findings suggested opportunities for further development, especially improving the resource's social interactivity. We recommend that further resource implementation includes student-educator and student-peer interactivity to maximise learning, and longitudinal evaluation of the resource.

RESUMO

When applied over the primary motor cortex (M1), anodal transcranial direct current stimulation (a-tDCS) could enhance the effects of a single motor imagery training (MIt) session on the learning of a sequential finger-tapping task (SFTT). This study aimed to investigate the effect of a-tDCS on the learning of an SFTT during multiple MIt sessions. Two groups of 16 healthy young adults participated in three consecutive MIt sessions over 3 days, followed by a retention test 1 week later. They received active or sham a-tDCS during a MIt session in which they mentally rehearsed an eight-item complex finger sequence with their left hand. Before and after each session, and during the retention test, they physically repeated the sequence as quickly and accurately as possible. Both groups (i) improved their performance during the first two sessions, showing online learning; (ii) stabilised the level they reached during all training sessions, reflecting offline consolidation; and (iii) maintained their performance level one week later, showing retention. However, no significant difference was found between the groups, regardless of the MSL stage. These results emphasise the importance of performing several MIt sessions to maximise performance gains, but they do not support the additional effects of a-tDCS.

RESUMO

With the rise of online instruction, a better understanding of the factors that contribute to belonging and motivation in these contexts is essential to creating optimal learning environments. Although group work is known to be beneficial to student success, few studies have investigated its role in the context of asynchronous online courses. The present study addresses this gap through a survey of 146 undergraduate students in an asynchronous online physiology lab over two semesters, one with required group work and one without group work. Students were surveyed to evaluate the influence of group work on their motivation and sense of belonging, as well as their perceptions of inclusive and exclusive features of the course. Students assigned to groups had a higher sense of belonging (P = 0.006) and beliefs about their competence (P = 0.002) and perceived lower effort and psychological costs associated with the course (P = 0.04 and 0.04, respectively) compared to students not assigned to groups. Students assigned to groups reported that peer interactions made them feel included in the course (70% of coded responses) while those not assigned to groups valued instructor interactions (51% of coded responses) as inclusive. Negative peer interactions were commonly reported as exclusive by students assigned to groups (28% of coded responses) while a lack of peer interactions (23% of coded responses) made students not assigned to groups feel excluded. These data indicate that assigning groups in asynchronous online courses is an effective way to increase student motivation and perceptions of belonging.NEW & NOTEWORTHY This study explores the effect of assigned group work in an asynchronous online physiology laboratory course on student motivation and belonging. Students' perceptions of belonging and competence-related beliefs were higher, and effort and psychological costs were lower, when assigned to groups compared to students not assigned to groups. Students assigned to groups noted peer interactions as the most inclusive aspect of the course, whereas instructor interactions were noted as inclusive by those not assigned group work.

RESUMO

BACKGROUND: Many of the educational institutions in developed countries have shifted to online learning. While transition from traditional to electronic learning (e-learning) has remained a great challenge in low-middle income countries, where limited resources for teaching and learning are important factors. Medical education involves not only lecturing but also deep understanding through laboratories and patient exposure. The debate about the effectiveness of e-learning in medical education is still in contradiction due to its limitations. This cross-sectional survey was conducted to assess pre-clinical undergraduate medical students' perception of their first online learning in a lower-middle income country. METHODOLOGY: The survey was conducted among the students who had participated in online learning during COVID-19 for at least a year. A total of 824 preclinical medical students who completed the survey from public and private medical universities in Sindh, Pakistan were included in the study. We used a validated online-based questionnaire, distributed through E-mail and social media platforms to assess the perception of students regarding their first online learning experience. RESULTS: The response rate of the survey was 87.9%. The mean age of students was 20.7 ± 3.8 years. 392/824 (47%) were males and 57% were females. Our study indicated that 613/824 (75%) of students were experiencing online learning for the very first time while 631/824 (77%) were facing technical issues like internet accessibility and lack of IT-related skills. 381/824 (46%) were not satisfied with the institute's readiness for online teaching. However, 79% (654/824) of participants were of the idea that traditional learning is more effective in developing their practical skills as compared to e-learning. Of note, 668/824 (81%) showed overall dissatisfaction with e-learning. CONCLUSION: Based on our study findings, we concluded that most students have a negative perception of e-learning. Difficulty in connectivity, electricity issues, less interaction with colleagues and teachers, and issues with the structure of online courses were the most frequently reported problems by the students.

RESUMO

BACKGROUND: Educating and raising awareness in cleft lip and palate future generations is one vital effort to ensure the improvement of cleft care and research in the future. This study reported the overview in organising and evaluating the Massive Open Online Course (MOOC) in Cleft Lip and Palate as the alternative way for students' capacity building outside their study program whilst also earning credits towards their studies. METHODS: Smile Train cleft charity generously donated recorded lectures from cleft experts around the world in which each of the experts agreed to provide one-hour live discussion sessions. The learning activities ranging from lectures, pre- and post-course evaluation, forum, live discussion sessions, virtual visits to Indonesian Cleft Centre, self-reflection assignments and final project. A survey was released to the participants to collect their feedback. RESULTS: The course mainly attracted dental students, and several allied health professional students. In total, 414 out of 717 participants registered for this MOOC managed to finish the course and received a certificate of completion which was run between August-October 2021. In general, participants positively received the course. CONCLUSIONS: The MOOC model and its objective of disseminating widespread information across geographical boundaries to enhance learning about cleft lip and palate treatment was achieved. This report serves as an example for other educational institutions and stakeholders who plan to use online educational engagement platforms to provide high-quality education and capacity building to participants in lower-middle income countries.

RESUMO

PURPOSE: Many health professions education programs involve people with lived experience as expert speakers. Such presentations may help learners better understand the realities of living with chronic illness or experiencing an acute health problem. However, lectures from only one or a small number of people may not adequately illustrate the perspectives and experiences of a diverse patient cohort. Additionally, logistical constraints such as public health restrictions or travel barriers may impede in-person presentations, particularly among people who have more restrictions on their time. Health professions education programs may benefit from understanding the potential effects of online patient-led presentations with a diverse set of speakers. We aimed to explore whether patient-led online learning modules about diabetes care would influence learners' responses to clinical scenarios and to collect learners' feedback about the modules. METHOD: This within-subjects randomized experiment involved 26 third-year medical students at Université Laval in Quebec, Canada. Participation in the experiment was an optional component within a required course. Prior to the intervention, participating learners responded to three clinical scenarios randomly selected from a set of six such scenarios. Each participant responded to the other three scenarios after the intervention. The intervention consisted of patient-led online learning modules incorporating segments of narratives from 21 patient partners (11 racialized or Indigenous) describing why and how clinicians could provide patient-centered care. Working with clinical teachers and psychometric experts, we developed a scoring grid based on the biopsychosocial model and set 0.6 as a passing score. Independent evaluators, blinded to whether each response was collected before or after the intervention, then scored learners' responses to scenarios using the grid. We used Fisher's Exact test to compare proportions of passing scores before and after the intervention. RESULTS: Learners' overall percentage of passing scores prior to the intervention was 66%. Following the intervention, the percentage of passing scores was 76% (p = 0.002). Overall, learners expressed appreciation and other positive feedback regarding the patient-led online learning modules. DISCUSSION: Findings from this experiment suggest that learners can learn to provide better patient-centered care by watching patient-led online learning modules created in collaboration with a diversity of patient partners.

RESUMO

BACKGROUND: Medical education requires the implementation of different teaching methods and strategies for future doctors to achieve broad learning objectives. This wide range of methods and strategies includes the use of Information Technologies. For a long time, there was a call for a change in medical education for blending new teaching approaches to lessen medical students' class time. The COVID-19 pandemic then sped up the transition to the new way of medical education and classroom lectures were quickly moved to a virtual environment. We expect that these changes will continue, and online learning will be one of the main teaching strategies in medical education. Therefore, educational experiences during the COVID-19 pandemic will improve our understanding of online learning and will help to develop blended medical school curricula in the future. For this reason, we aimed to determine students' overall satisfaction with their online learning experience and to define the main factors affecting students' satisfaction with their online learning program at Cerrahpasa Medical Faculty. METHODS: A cross-sectional survey study was conducted to determine medical students' overall satisfaction with online learning methods and to identify factors associated with positive and negative satisfaction levels. A questionnaire, consisting of 24 questions to collect demographic characteristics, factors associated with online education experience and overall satisfaction levels was developed and distributed to 1600 medical students. Multivariable linear regression analysis was used to determine the factors associated with positive and negative satisfaction levels. RESULTS: Regression analysis showed that being familiar with online teaching techniques (ß = 0.19, 95% CI [0.07, 0.30], faculty members' higher online teaching skill levels (ß = 0.42, 95% CI [0.32, 0.51], interactive online teaching approaches (ß = 0.54, 95% CI [0.41, 0.67], having a personal workspace (ß = 0.43, 95% CI [0.19, 0.67], and a self-reported longer attention span (ß = 0.75, 95% CI [0.57, 0.92] were associated with higher overall satisfaction with online learning. The occurrence of technical problems (ß = -0.19, 95% CI [-0.26, -0.12] was associated with lower overall satisfaction. CONCLUSIONS: Higher online teaching skills of faculty members, use of interactive approaches, students' familiarity with online teaching techniques, provision of a personal workspace, and self-reported longer attention spans positively contributed to higher levels of student satisfaction with online learning. Considering the increasing significance of online educational methods, our study identified key components that affect students' level of satisfaction. This information might contribute to the development of online educational programs in the future.

RESUMO

BACKGROUND: Previous research indicates that reflection can foster medical communication competence. However, best practices for embedding reflection in online medical education are missing. This study examined how reflection processes can be promoted and embedded in an e-learning course on physician-patient communication to foster learning. METHODS: We investigated three differently designed e-learning conditions featuring different proportions of reflection triggers and compared their effects on students' reflections. We had 114 medical students in their first clinical year complete one of the variants: video modelling (VM, n = 39), video reflection (VR, n = 39), or a variant merging both approaches (VMR, n = 36). Each student wrote a total of nine reflections based on the same guiding questions at three time points embedded in the course. The students' levels of reflection were measured using an adapted version of the REFLECT rubric (scale 0-18). RESULTS: Students of all course variants achieved good levels of reflection beyond the descriptive level at all three time points, with no significant differences between the variants. The mean reflection scores at the end of the course were M = 14.22 for VM (SD = 2.23), M = 13.56 for VR (SD = 2.48), and M = 13.24 for VMR (SD = 2.21). Students who completed VM showed significantly improved levels of reflection over the course, whereas we found no statistically significant development for those in VR or VMR. The reflection scores correlated significantly positively with each other, as did the text lengths of the written reflections. Reflection scores also correlated significantly positively with text length. CONCLUSIONS: Our study offers a teaching strategy that can foster good levels of reflection, as demonstrated in the three e-learning variants. The developed reflection prompts can be easily embedded in various e-learning environments and enable reflections of good quality, even in settings with limited available teaching time.

RESUMO

INTRODUCTION: Blended learning, which integrates classroom face-to-face teaching with both asynchronous and synchronous online learning elements, has swiftly gained acceptance in educational environments. However, the implementation of blended learning presents challenges that impact all stakeholders, necessitating thoughtful consideration. Teachers play a central role in shaping the instructional experience among these stakeholders. To fully realize the potential of comprehensive blended learning, it is imperative to identify the challenges faced by these teachers and develop strategies that sensibly address and overcome them. METHODOLOGY: A qualitative exploratory study was conducted with twelve teachers involved in the postgraduate blended learning health professions program at Khyber Medical University, Peshawar in 2022. One-on-one semi-structured Interviews were conducted via WhatsApp/ZOOM, transcribed by Otter AI, coded on NVivo & analyzed using Braun/Clarke's Thematic Analysis. RESULTS: Three themes of challenges faced by teachers of postgraduate blended learning programs were constructed namely (1) Skills, such as (i) digital, (ii) instructional, and (iii) online class management, and (2) Administrative barriers in terms of (iv) resources (iv) training, and (3) Faculty resistance. CONCLUSION: This study provides profound insights into the daunting challenges that postgraduate blended learning program teachers encounter in terms of skills, administrative barriers, and faculty resistance. These findings offer a valuable opportunity for program directors to identify the critical requirements of these faculties in their pursuit of effective teaching and learning, ultimately transforming the landscape of blended education. This study emphasizes the need for ongoing faculty development and institutional support to address the identified challenges and improve the quality of postgraduate blended-learning programs.

RESUMO

BACKGROUND: The abrupt onset of the COVID-19 pandemic compelled universities to swiftly establish online teaching and learning environments that were not only immediately deployable but also conducive to high-quality education. This study aimed to compare the effectiveness of the online synchronous and asynchronous teaching formats in the dermatology lecture for undergraduate medical students, including academic performance, self-efficacy, and cognitive load. METHODS: A total of 170 fourth-year undergraduate medical students attending the dermatology lecture were included. The lecture was delivered using both the synchronous method (live online lecture via Webex meeting) and the asynchronous method (lecture videos shared on YouTube). The students had the freedom to choose their preferred method of attending the online lecture. The study assessed three main aspects: (1) learning outcomes measured through pretest, posttest, and retention test scores; (2) cognitive load experienced by students, including mental load and mental effort measured using eight items; and (3) satisfaction levels with each online teaching format. RESULTS: In this study, 70 students opted for the synchronous online lecture, while 100 students chose the asynchronous online lecture. Both synchronous and asynchronous teaching methods exhibited significant improvements in post and retention test scores compared to the pretest. Satisfaction levels, rated on a scale of 0-5, were generally high for both teaching methods, with no significant differences observed (4.6 for synchronous, 4.53 for asynchronous; p =.350). Regarding cognitive load, the synchronous method showed a significantly lower level than the asynchronous method (p =.0001). Subgroup analysis revealed no difference in mental effort (p =.0662), but the level of mental load was lower in the synchronous method (p =.0005). CONCLUSIONS: Both synchronous and asynchronous online teaching methods demonstrated improvements in learning outcomes and high levels of student satisfaction. However, the cognitive load experienced by students was lower in the synchronous setting compared to the asynchronous setting. These findings remind health professions educators that they would consider the students' cognitive load when designing online curricula.

RESUMO

OBJECTIVE: Mobile-based educational software offers a wealth of resources that can foster the growth of learners and facilitate the creation of an interactive learning environment. This environment encourages both students and instructors to engage in exploration and the examination of various medical issues. The objective of this study is to design, implement, and evaluate an electronic educational program focused on common medical conditions, specifically tailored for medical students and accessible through mobile phones. METHOD: The study was conducted following an action research approach, which comprised four key stages: needs assessment, application design, training, and evaluation. This research took place at the Kermanshah University of Medical Sciences' Medical School. In the needs assessment phase, a formal survey was distributed to the teaching faculty members, requesting them to identify diseases and medical issues of high importance for medical interns' education that were suitable for virtual teaching. Each faculty member was asked to prioritize a minimum of three and a maximum of seven cases. Subsequently, 10 faculty members from various departments completed the survey, leading to the identification of 47 common diseases after eliminating duplicates. These 47 cases were then presented to 30 medical interns, who were asked to select the 20 most significant cases. The 20 diseases with the highest statistical frequency were selected for further development due to resource constraints. The mobile application was developed for the Android platform using the Java programming language and the Android Studio development environment. To assess the application's effectiveness from the students' perspective, a questionnaire was designed, encompassing 25 questions across five domains: satisfaction, performance, learning, usability, and educational effectiveness. The questionnaire employed a Likert scale, with response options ranging from 'completely disagree' to 'completely agree,' scored from 1 to 5. One hundred medical interns and trainees were invited to participate in the evaluation, with 92 of them completing the questionnaires. RESULTS: The findings revealed a significant disparity in the average scores between students who underwent traditional teaching methods and those who engaged in mobile-based app-assisted education. This discrepancy was statistically significant across all three examined components. CONCLUSION: Mobile-based learning represents a burgeoning educational approach with profound implications for healthcare education and the enhancement of patient care quality. The widespread integration of mobile phones into the educational framework offers a flexible teaching paradigm, fostering the potential for continuous lifelong learning.

RESUMO

BACKGROUND: Mnemonic techniques are memory aids that could help improve memory encoding, storage, and retrieval. Using the brain's natural propensity for pattern recognition and association, new information is associated with something familiar, such as an image, a structure, or a pattern. This should be particularly useful for learning complex medical information. Collaborative documents have the potential to revolutionize online learning because they could increase the creativity, productivity, and efficiency of learning. The purpose of this study was to investigate the feasibility of combining peer creation and sharing of mnemonics with collaborative online documents to improve pathology education. METHODS: We carried out a prospective, quasi-experimental, pretest-posttest pilot study. The intervention group was trained to create and share mnemonics in collaborative documents for pathological cases, based on histopathological slides. The control group compared analog and digital microscopy. RESULTS: Both groups consisted of 41 students and did not reveal demographic differences. Performance evaluations did not reveal significant differences between the groups' pretest and posttest scores. Our pilot study revealed several pitfalls, especially in instructional design, time on task, and digital literacy, that could have masked possible learning benefits. CONCLUSIONS: There is a gap in evidence-based research, both on mnemonics and on CD in pathology didactics. Even though, the combination of peer creation and sharing of mnemonics is very promising from a cognitive neurobiological standpoint, and collaborative documents have great potential to promote the digital transformation of medical education and increase cooperation, creativity, productivity, and efficiency of learning. However, the incorporation of such innovative techniques requires meticulous instructional design by teachers and additional time for students to become familiar with new learning methods and the application of new digital tools to promote also digital literacy. Future studies should also take into account validated high-stakes testing for more reliable pre-posttest results, a larger cohort of students, and anticipate technical difficulties regarding new digital tools.
