RESUMEN

BACKGROUND: Medical education offers the foundational base for future healthcare professionals, with basic sciences playing a pivotal role in providing essential knowledge and skills for clinical practice. However, the long-term retention and application of this knowledge in clinical practice remain a significant challenge. This systematic review synthesised global evidence from diverse studies on the short / long-term retention and clinical application of basic sciences among medical doctors. METHODS: A comprehensive search was conducted across six databases, including Web of Science, Scopus, Medline, CINAHL, Emcare, and Informit. The review included studies that encompassed a variety of study designs, participant groups, and educational interventions. The Quality Assessment with Diverse Studies (QuADS) tool was utilised to assess the quality of the reviewed studies. RESULTS: A total of 10 studies were included in the review. The findings revealed that rehearsals significantly optimise the retention of basic science knowledge among medical practitioners. Retention varied by discipline, with medical practitioners retaining more knowledge in anatomy (mean scores ranging from 45.0 to 82.9%), while microbiology had the lowest retention score (39.1%). Factors influencing retention included age, gender, and curriculum type. Educational interventions such as targeted courses, integration of basic sciences with clinical skills, generative retrieval and continuous quality improvement in the curriculum were found to enhance both knowledge retention and clinical reasoning. The concept of 'encapsulated knowledge' demonstrates that integrated basic science knowledge helps in synthesising clinical presentations, reducing the need for detailed recall as clinical experience increases. The reviewed studies primarily involved interns and surgeons, leaving a significant gap in research for specialties like internal medicine and primary care/ general practice. CONCLUSION: Detailed retention of basic science knowledge may diminish over time; however, the conceptual framework remains essential for ongoing learning and clinical reasoning. This review's findings highlight the need for specialised educational interventions to improve long-term retention. Continuous professional development and targeted educational techniques are vital for maintaining clinical competence and applying basic science knowledge effectively throughout a medical career. Further research is needed to address gaps in specialty-specific knowledge application and the impact of different instructional methods.

RESUMEN

BACKGROUND: The Indian National Medical Council has incorporated the Basic Life Support (BLS) course in the foundation course of the undergraduate (MBBS) medical curriculum. However, medical teachers raise concerns about how training would affect the retention of Basic Life Support (BLS) abilities in the longer run. So, the current study assesses the knowledge and retention of BLS skills among first-year MBBS students over one year. METHODS: We included one hundred first-year MBBS students in our study who were trained for BLS, including theory, demonstrations and hands-on training using mannequins. Theoretical knowledge was assessed using pre-test and post-test questionnaires. At the same time, the skills were evaluated using Directly Observed Procedural Skills (DOPS) scores before, just after the training session, and again after one month, six months, and one year. Course feedback was also taken from the students after completing the sessions. RESULTS: There was a statistically significant difference between pre-and post-test knowledge scores, indicating that training improved their knowledge. (p < 0.001) There was also a statistically significant difference between pre-and post-test skills using DOPS (p < 0.001). There was no significant difference in the score when DOPS was conducted at one month, but a significant decrease in their skills was seen at six months and one year when compared with the Post Skill Score. (P < 0.001) CONCLUSIONS: The first-year medical students' knowledge and skills were enhanced by BLS training coupled with practical sessions. Such waning skills necessitate repeating the training at periodic intervals to reinform retention of skills acquired during BLS training.

RESUMEN

Ventral tegmental area (VTA) dopamine (DA) neurons have been found to substantially associate with post-traumatic stress disorder (PTSD) pathology, however, whether and how these DA neurons affect fear memory management in PTSD individuals remains largely unknown. In this study, we utilized auditory conditioned foot-shock to evaluate the fear memory retrieval and retention characteristics in a single prolonged stress-induced PTSD rat model. We employed chemogenetic technology to specifically activate VTA DA neurons to examine the freezing behaviors responding to the conditioned stimuli. In vivo extracellular electrophysiological analyses were used to identify VTA DA neuronal firing alterations due to the chemogenetic activation. The results demonstrated that PTSD model rats showed comparable fear memory retrieval (Day 2 after the conditioned foot-shock), but significant enhancements in fear memory retention (Day 8 after the conditioned foot-shock), compared to normal control rats. Chemogenetic activation of VTA DA neurons markedly diminished the retention of fear memory in PTSD model rats, which appeared concomitantly with increases in the firing activities of the DA neurons. These findings revealed that PTSD induced the persistence of fear memory, which could be attenuated by activation of VTA DA neurons. It is presumed that VTA dopaminergic signals may serve as a prospective option for PTSD treatment.

RESUMEN

BACKGROUND: Student knowledge acquisition and retention are essential in nursing training. This study examined differences in content knowledge acquisition and retention between traditional and flipped classroom (FC) formats. METHOD: A pretest-posttest quasiexperimental design with a follow-up test was used for this study of associate degree nursing students in a Hong Kong community college. The control group (n = 141) included nursing students in a traditional classroom (TC) setting before COVID-19 compared with nursing students in an FC (n = 130) setting during the pandemic. The effects were evaluated before the course, postcourse, and 3 months after the course. RESULTS: Content knowledge scores for both groups improved after the course. Students in the FC performed better in the short-term (posttest immediately after the course) and long-term (follow-up-test 3 months later) than students in the TC. CONCLUSION: Implementing the FC method effectively promoted students' knowledge acquisition and retention. [J Nurs Educ. 2024;63(8):501-506.].

RESUMEN

INTRODUCTION: The Neonatal Resuscitation Programme (NRP) was first introduced in Malaysia in 1996 to train doctors and nurses working in paediatrics and obstetrics departments who are involved with the care of newborns soon after delivery. Prompt and effective neonatal resuscitation has been documented to reduce mortality and neonatal asphyxia. The programme has been revised every five years and is now in the 8th edition. NRP training was made into a key performance indicator (KPI) by the Ministry of Health in 2016 for all house officers to be trained in this programme during their 2-year posting and this is usually conducted during the paediatric posting. This study aims to evaluate the retention of their knowledge, skills and competency at 3, 6, and 9 months after the initial NRP training. MATERIALS AND METHODS: A total of 34 house officers were enrolled in the study on joining the paediatric unit of Hospital Kulim. They were given the "Textbook of NRP" to prepare for the theory paper that consisted of 30 multiplechoice questions (MCQs). Two to four weeks later they went through a day of training on the resuscitation of the newborn using low-fidelity simulation manikins. They were taught to recognise a newborn who needed resuscitation after delivery, prepared the equipment for resuscitation and learned the skills of resuscitation. The skills included the initial steps, bag valve mask ventilation, intubation, cardiac massage, umbilical vein cannulation and use of medications. They were also taught the performance of objective structured clinical examination (OSCE) A and B. They were evaluated at 3, 6, and 9 months after the completion of their training using the MCQs and the performance checklist in the NRP textbook. RESULTS: The results showed that there was a significant reduction in their knowledge retention as shown by their performance in multiple choice questions. Similarly, there was a significant loss of competency in their skills and competency in resuscitation using bag mask ventilation, intubation and performance of OSCE A and OSCE B. However, their performance at initial steps showed no significant reduction. CONCLUSION: In view of the observed deterioration a refresher course in NRP before transferring out to the districts is recommended to improve their overall performance.

RESUMEN

Undergraduate introductory human anatomy and human physiology courses are either taught as discipline-specific or integrated anatomy and physiology (A&P) sequences. An institution underwent a curricular revision to change the course approach from discipline-specific Human Anatomy and Human Physiology to an integrated A&P I and II sequence, allowing the unique opportunity to explore the potential role of contextual learning in academic achievement and content retention. Mediation and moderation analysis was used to evaluate lecture examinations, laboratory practical examinations, and anatomical content retention between the different course approaches. Undergraduate students in the integrated A&P I course approach performed significantly better on lecture assessments and had a higher anatomy content retention rate at the end of the year than students enrolled in the standalone Human Anatomy course. The lecture examination averages between Human Physiology and A&P II (the second course in the sequence), as well as the anatomy laboratory practical examinations, were not significantly different between discipline-specific and integrated course approaches. The results suggest contextual learning-providing physiological context to anatomical structures-increases the anatomical content retention and academic achievement overall.

RESUMEN

BACKGROUND: The effectiveness of instructional videos as a stand-alone tool for the acquisition of practical skills is yet unknown because instructional videos are usually didactically embedded. Therefore, we evaluated the acquisition of the skill of a humeral intraosseous access via video in comparison to that of a self-study with an additional retention test. METHODS: After ethical approval, we conducted two consecutive studies. Both were designed as randomised controlled two-armed trials with last-year medical students as independent samples at our institutional simulation centre of a tertiary university hospital centre. In Study 1, we randomly assigned 78 participants to two groups: Vid-Self participants watched an instructional video as an intervention, followed by a test, and after seven days did a self-study as a control, followed by a test. Self-Vid ran through the trial in reverse order. In Study 2, we investigated the influence of the sequence of the two teaching methods on learning success in a new sample of 60 participants: Vid-Self watched an instructional video and directly afterward did the self-study followed by a test, whereas Self-Vid ran through that trial in reverse order. In Studies 1 and 2, the primary outcome was the score (worst score = 0, best score = 20) of the test after intervention and control. The secondary outcome in Study 1 was the change in score after seven days. RESULTS: Study 1: The Vid-Self (Participants n = 42) was superior to the Self-Vid (n = 36) (mean score 14.8 vs. 7.7, p < 0.001). After seven days, Self-vid outperformed Vid-Self (mean score 15.9 vs. 12.5, p < 0.001). Study 2: The Vid-Self (n = 30) and Self-Vid (n = 30) scores did not significantly differ (mean 16.5 vs. mean 16.5, p = 0.97). CONCLUSION: An instructional video as a stand-alone tool effectively promotes the acquisition of practical skills. The best results are yielded by a combination of an instructional video and self-study right after each other, irrespective of sequence. TRIAL REGISTRATIONS: ClinicalTrials.gov: NCT05066204 (13/04/2021) (Study 1) and NCT04842357 (04/10/2021) (Study 2).

RESUMEN

The effect of practice schedule on retention and transfer has been studied since the first publication on contextual interference (CI) in 1966. However, strongly advocated by scientists and practitioners, the CI effect also aroused some doubts. Therefore, our objective was to review the existing literature on CI and to determine how it affects retention in motor learning. We found 1255 articles in the following databases: Scopus, EBSCO, Web of Science, PsycINFO, ScienceDirect, supplemented by the Google Scholar search engine. We screened full texts of 294 studies, of which 54 were included in the meta-analysis. In the meta-analyses, two different models were applied, i.e., a three-level mixed model and random-effects model with averaged effect sizes from single studies. According to both analyses, high CI has a medium beneficial effect on the whole population. These effects were statistically significant. We found that the random practice schedule in laboratory settings effectively improved motor skills retention. On the contrary, in the applied setting, the beneficial effect of random practice on the retention was almost negligible. The random schedule was more beneficial for retention in older adults (large effect size) and in adults (medium effect size). In young participants, the pooled effect size was negligible and statically insignificant.

RESUMEN

OBJECTIVES: The need for cardiopulmonary resuscitation (CPR) training dissemination in the community could be resolved by mass school training programmes. However, the availability of instructors remains an unsolved problem. Our purpose was to investigate the effects of three different instructor types: healthcare professionals, schoolteachers and peer students, on CPR skills retention of secondary school students 6 months after training. DESIGN: The study was designed as a prospective randomised single-blinded controlled trial. The study ended before reaching the target sample size for the schoolteacher arm. SETTING AND PARTICIPANTS: Students from three different secondary schools in Heraklion, Greece, were recruited to attend CPR training. INTERVENTIONS: All participants received a manual and a digital video disc demonstrating the CPR/automated external defibrillator (AED) algorithm, followed by hands-on training. They were randomly assigned to receive training by either healthcare professionals, schoolteachers or peer students, who had previously been trained appropriately. OUTCOME MEASURES: CPR knowledge and skill retention were evaluated immediately (secondary outcome) and 6 months after training (primary outcome), using a knowledge questionnaire, skill checklists and feedback device. RESULTS: 408 students (199 girls - two non-binary) were enrolled in the study with a median age of 13 (IQR 12-14) years. A total of 255 students (125 girls) were reassessed at 6 months. Preliminary analysis of the data revealed no statistically significant differences between the three groups regarding factual knowledge immediately after training (p=0.226) and at 6 months (p=0.867). Immediately after training, more students trained by healthcare professionals or teachers performed safe defibrillation (p<0.000); however, this finding was dissipated at 6-month reassessment (p=0.202). Compliance with the CPR algorithm and the quality of hands-only CPR were not different (p>0.05) among the groups. CONCLUSIONS: The type of instructor did not affect the CPR knowledge and skill retention of students 6 months after training. Schoolchildren acting as peer instructors could be an effective alternative to healthcare professionals and schoolteachers, although further studies are needed.

RESUMEN

The traditional short- and long-term storage view of information processing and the levels-of-processing view both discuss the forgetting of information over time. In the traditional stage view, there is loss of at least poorly encoded information across several seconds when the information cannot be rehearsed (e.g., Ricker et al., 2020, Learning, Memory, and Cognition, 46, 60-76). In the levels-of-processing approach, information that is encoded in a shallow manner is lost more quickly over time than deeply-encoded information (Craik & Lockhart, 1972, Journal of Verbal Learning and Verbal Behavior, 11, 671-684.). Previous studies of the depth of encoding, however, have mostly been conducted using delayed tests, so there are few studies directly comparing the rate of forgetting over time for information as a function of different depths of encoding. We manipulated the level of processing with immediate recall in a modified Brown-Peterson task. An effect of the level of processing was robust, but evidence of forgetting across retention intervals was not always observed. When encoding time was curtailed (in Experiments 3 and 4), we found main effects of both the level of processing and the retention interval, but no interaction between the two variables. The results suggest that the depth-of-encoding effect may occur during the initial encoding of items, but without differential forgetting within the range of retention intervals that we examined (0-18 s), in contrast to the suggestion by Craik and Lockhart. Further work is needed to determine whether the depth-of-processing effect would grow over longer intervals.

RESUMEN

BACKGROUND: Although adding embodied instructors on the screen is considered an effective way to improve online multimedia learning, its effectiveness is still controversial. The level of realism of embodied on-screen instructors may be an influencing factor, but it is unclear how it affects multimedia learning. AIMS: We explored whether and how embodied on-screen instructors rendered with different levels of realism in multimedia lessons affect learning process and learning outcomes. SAMPLES: We recruited 125 college students as participants. METHODS: Students learned about neural transmission in an online multimedia lesson that included a real human, cartoon human, cartoon animal or no instructor. RESULTS: Students learning with cartoon human or cartoon animal instructors tended to fixate more on the relevant portions of the screen and performed better on retention and transfer tests than no instructor group. The real human group fixated more on the instructor, fixated less on the relevant portion of the screen and performed worse on a retention test in comparison to the cartoon human group. Fixation time on the instructor fully mediated the relationship between instructor realism and retention score. CONCLUSIONS: The addition of embodied on-screen instructors can promote multimedia learning, but the promotion effect would be better if the embodied instructor was a cartoon animal or cartoon human rather than a real human. This suggests an important boundary condition in which less realism of on-screen embodied instructors produces better learning processes and outcomes.

RESUMEN

OBJECTIVES: This study tested the effects of combining two bandwidth knowledge of performance (KP) on a complex sports motor skill. METHOD: Twenty-two elementary students were divided into combined wide and narrow bandwidth KP (WNG) and control group (CG). The task was the volleyball serve, whose goal was to hit the bull's eye center of a target lying on the floor on the opposite side of the court. The study was composed of a pre-test, acquisition phase and retention test, and had three measures (pre-test, intermediate test, and retention test) with 15 serves recorded each. The acquisition phase consisted of 252 trials. The WNG had a wide bandwidth KP in the first half of the acquisition phase and a narrow one in the second. The CG received KP in all trials. The effects of bandwidth KP were analyzed separately to infer parameters and skill structure learning. RESULTS: Both groups improved the skill structure from the first to the intermediate test, but only WNG also improved on the retention test. The parameters accuracy improved only on retention compared to the pre-test and intermediate test but had no difference between groups. CONCLUSION: Providing information using the bandwidth KP led to an initial engagement and prioritization of skill structure learning.

RESUMEN

Across-task binding is defined as the stimulus/response of one task being linked to the response of another task. The purpose of the present experiment was to determine across-task binding in a continuous movement sequence task with an auditory task of high and low pitch tones and the development of a movement sequence representation. According to the two systems theory of sequence learning, we expected that the developed representation in the across-task binding context relies on the multi-dimensional system rather than on the unidimensional system which is restricted to a set of modules where each module processed information along one task/dimension. An inter-manual transfer design was used to disentangle the sequence representations. The mirror transfer test required the same pattern of muscle activation and joint angles (motor coordinates) in the contralateral limb as experienced during the acquisition phase, while in the non-mirror transfer test, the visual-spatial locations (spatial coordinates) of the target waveform were reinstated. The main finding was that consistently combining visual-spatial positions in a sequence and auditory dimensions such as the tone pitch does not rely on a multidimensional system as predicted by the two-systems theory.

RESUMEN

During vocabulary instruction, it is important to teach words until their representations are robust enough to be retained. For adults, the number of training sessions a target item is successfully retrieved during training predicts the likelihood of post-training retention. To assess this relationship in children, we reanalyzed data from Gordon et al. (2021b, 2022). Four- to six-year-old children completed six training days with word form-object pairs and were tested one month later. Results indicate that the number of training sessions that a word form was retrieved was positively related to post-training retention. We discuss implications for vocabulary instruction and interventions.

RESUMEN

Mind wandering occurs when attention becomes disengaged from the here-and-now and directed toward internally generated thoughts; this is often associated with poorer performance on educationally significant tasks. In this study, 8- to 9-year-old children (N = 60) listened to audio stories embedded with intermittent thought probes that were used to determine if participants' thoughts were on or off task. The key objective was to explore the impact of probe-caught mind wandering on both immediate and delayed memory retention. Children reported being off task approximately 24% of the time. Most inattention episodes were classified as task-unrelated thoughts (i.e., 'pure' instances of mind wandering, 9%) or attentional failures due to distractions (9%). Higher frequency of mind wandering was strongly associated with poorer memory recall, and task-unrelated thoughts strongly predicted how well children could recall components of the audio story both immediately after the task and after a 1-week delay. This study is the first to demonstrate the impact of mind wandering on delayed memory retention in children. Results suggest that exploring mind wandering in the foundational years of schooling could provide the necessary empirical foundation for the development of practical interventions geared toward detecting and refocusing lapses of attention in educational contexts.

RESUMEN

When reading a text in school, the goal is both text comprehension and text retention. We examined the effects of the learning strategies summarization and factual retrieval practice on third- and fourth-grade pupils' text comprehension and retention of factual knowledge from a text, using restudy as a control condition. The experiment was conducted in an authentic classroom setting, with teachers executing the experiment using original course materials. In 2016, 57 regular third- and fourth-grade pupils (M = 9.04 years old) read three different texts, and each applied three different learning strategies (summarization, retrieval practice and restudy, which were counterbalanced across texts) in subsequent practice sessions. After a 2-week delay, a final test was administered. The learning strategy summarization had a larger positive effect on text comprehension than factual retrieval practice, but had a similar effect compared to restudy. The learning strategy factual retrieval practice had a larger positive effect on text retention than both summarization and restudy. Implications for educational practice are discussed.

RESUMEN

PURPOSE: Podcasts are commonly used by residents as part of their learning, with many listening concomitantly with other activities (e.g., driving and exercise). The effects of exercise on learning are controversial, with some suggesting potential benefit and others suggesting impaired learning. This study examined whether exercise influences knowledge acquisition and retention among resident physicians listening to a podcast while exercising versus those with undistracted listening. METHOD: This multicenter, randomized, crossover trial assessed emergency medicine residents across 5 U.S. institutions from September 2022 to January 2023. Residents were randomized to a group that listened to one 30-minute podcast while seated or a group that listened to a 30-minute podcast while engaging in 30 minutes of continuous aerobic exercise, with stratification by site and postgraduate year. Within 30 minutes of completing the podcast, they completed a 20-question multiple-choice test. They subsequently crossed over to the other intervention and listened to a different 30-minute podcast followed by another 20-question test. Each podcast focused on emergency medicine-relevant journal articles that had not been covered in journal club or curriculum at any sites. Residents also completed a 40-question delayed recall test with separate questions on both podcasts at 30 days. RESULTS: Ninety-six residents were recruited for the study, with 95 (99.0%) completing the initial recall portion and 92 (97.0%) completing the delayed recall tests. No statistically significant differences were found between the exercise and seated cohorts on initial recall (74.4% vs 76.3%; d = -0.12; 95% CI, -0.33 to 0.08; P = .12) or delayed recall (52.3% vs 52.5%; d = -0.01; 95% CI, -0.22 to -0.19; P = .46). CONCLUSIONS: Exercising while listening to podcasts did not appear to meaningfully affect knowledge acquisition or retention at 30 days when compared with listening while seated and undistracted.

RESUMEN

Educational efficiency is the predetermining factor for increasing the survival rate of patients with cardiac arrest. Virtual reality (VR) simulation could help to improve the skills of those undergoing basic life support-automated external defibrillation (BLS-AED) training. Our purpose was to evaluate whether BLS-AED with virtual reality improves the skills and satisfaction of students enrolled in in-person training after completing the course and their retention of those skills 6 months later. This was an experimental study of first-year university students from a school of health sciences. We compared traditional training (control group-CG) with virtual reality simulation (experimental group-EG). The students were evaluated using a simulated case with three validated instruments after the completion of training and at 6 months. A total of 241 students participated in the study. After the training period, there were no statistically significant differences in knowledge evaluation or in practical skills when assessed using a feedback mannequin. Statistically significant results on defibrillation were poorer in the EG evaluated by the instructor. Retention at 6 months decreased significantly in both groups. The results of the teaching methodology using VR were similar to those obtained through traditional methodology: there was an increase in skills after training, and their retention decreased over time. Defibrillation results were better after traditional learning.

RESUMEN

The acquisition and retention of knowledge is affected by a multitude of factors including amount of practice, elapsed time since practice occurred, and the temporal distribution of practice. The third factor, temporal distribution of practice, is at the heart of research on the spacing effect. This research has consistently shown that separating practice repetitions by a delay slows acquisition but enhances retention. The current study addresses an empirical gap in the spacing effects literature. Namely, how does the allocation of a fixed number of practice repetitions among multiple sessions impact learning and retention? To address this question, we examined participants' acquisition and retention of declarative knowledge given different study schedules in which the number of practice repetitions increased, decreased, or remained constant across multiple acquisition sessions. The primary result was that retention depended strongly on the total number of sessions in which an item appeared, but not on how practice repetitions were distributed among those sessions. This outcome was consistent with predictions from a computational cognitive model of skill acquisition and retention called the Predictive Performance Equation (PPE). The success of the model in accounting for the patterns of performance across a large set of study schedules suggests that it can be used to tame the complexity of the design space and to identify schedules to enhance knowledge acquisition and retention.
