Hybrid teaching

R M Nataraja, N Webb, P J Lopez
Surgical training has changed radically in the last few decades. The traditional Halstedian model of time-bound apprenticeship has been replaced with competency-based training. In our previous article, we presented an overview of learning theory relevant to clinical teaching; a summary for the busy paediatric surgeon and urologist. We introduced the concepts underpinning current changes in surgical education and training. In this next article, we give an overview of the various modalities of surgical simulation, the educational principles that underlie them, and potential applications in clinical practice...

Knowledge deficits of transfusion medicine are prevalent among learners and practicing physicians. In the past, the transfusion medicine community has thoughtfully defined the content of transfusion medicine curriculums through Transfusion Medicine Academic Award Group and The Academy of Clinical Laboratory Physicians and Scientists. The manner in which the curriculum should be delivered has been less carefully examined and defined. We completed an observational study in which we analyzed 3 different teaching techniques: in-person faculty-led simulation curriculum consisting of didactic session and simulation ("Simulation group"); hybrid education with a combination of online materials and short in-person simulation ("Hybrid group"); and online-only education module, which delivered the whole curricular content through a variety of online materials and videos ("Online-only group")...

PURPOSE: A number line consisting of Arabic numerals is a commonly used instructional tool for teaching price comparison. However, typical number lines lack concrete visual cues, which may benefit students with autism spectrum disorders (ASD) who have not yet mastered the representation of Arabic numerals. METHOD: This study investigated the effects of additional visual cues (i.e., dots) by comparing two types of app-based number line conditions: number lines with and without dots...

American Indian and Alaska Native (AIAN) youth are characterized by high rates of pregnancy and risky sexual behavior. Reaching these youth with culturally appropriate interventions is difficult due to geographic dispersion and cultural isolation. Online interventions can provide opportunities for reaching and engaging AIAN youth. However, electronic interventions are also impersonal and this can be culturally incongruous for AIANs and other populations for whom traditional ceremonies, practices and patterns of interpersonal communication are central...

Background and aims:  EUS-guided biliary drainage (EUS-BD) and rendezvous (EUS-RV) are acceptable rescue options for patients with failed endoscopic retrograde cholangiopancreatography (ERCP). However, there are limited training opportunities at most centers owing to low case volumes. The existing models do not replicate the difficulties encountered during EUS-BD. We aimed to develop and validate a model for stepwise learning of EUS-BD and EUS-RV, which replicates the actual EUS-BD procedures...

BACKGROUND: Internationally, medical schools have long used a variety of approaches to develop hybrid Problem based learning (PBL) curricula. However, Team-based learning (TBL), has gained recent popularity in medical education. TBL maintains the advantages of small group teaching and learning, but in contrast to Problem-based learning (PBL), does not require large numbers of tutors. In 2016, TBL was introduced to Year 1 of the Sydney Medical Program (SMP).This study sought to compare students' perceptions of using TBL in place of PBL...

Therapy is not simply a domain or form of medical practice, but also a metaphor for and a performance of medicine, of its functions and status, of its distinctive mode of action upon the world. This article examines medical treatment or therapy (in Russian lechenie), as concept and practice, in what came to be known in Russia as defectology (defektologiia) - the discipline and occupation concerned with the study and care of children with developmental pathologies, disabilities and special needs. Defectology formed an impure, occupationally ambiguous, therapeutic field, which emerged between different types of expertise in the niche populated by children considered 'difficult to cure', 'difficult to teach', and 'difficult to discipline'...

In situ hybridization is a widely employed technique allowing spatial visualization of gene expression in fixed specimens. It has greatly advanced our understanding of biological processes, including developmental regulation. In situ protocols are today routinely followed in numerous laboratories, and although details might change, they all include a hybridization step, where specific antisense RNA or DNA probes anneal to the target nucleic acid sequence. This step is generally carried out at high temperatures and in a denaturing solution, called hybridization buffer, commonly containing 50% (v/v) formamide - a hazardous chemical...

BACKGROUND: The clinical magnetic resonance imaging (MRI) images may get corrupted due to the presence of the mixture of different types of noises such as Rician, Gaussian, impulse, etc. Most of the available filtering algorithms are noise specific, linear, and non-adaptive. OBJECTIVE: There is a need to develop a nonlinear adaptive filter that adapts itself according to the requirement and effectively applied for suppression of mixed noise from different MRI images...

Although the hybrid chronic total occlusion (CTO) algorithm had many excellent recommendations, there has been infrequent adoption in the Asia Pacific region. The Asia Pacific CTO club propose an algorithm for case selection based on the Japan-CTO score and a new CTO algorithm, which is applicable globally. This algorithm allows for differing skill sets and equipment availability and contains practical teaching for CTO percutaneous coronary intervention. Similar to the hybrid algorithm there are 3 main questions that determine whether the primary approach is antegrade or retrograde: 1) is there proximal cap ambiguity; 2) is the distal vessel of poor quality; and 3) are there interventional collaterals present...

Many CpG island detection methods have been proposed based on sliding window and clustering technology, but the accuracy of these methods is proportional to the time required. Therefore, an accurate and rapid method for identifying CpG islands remains an important challenge in the complete human genome. We propose a hybrid method CpGTLBO to detect the CpG islands in the human genome. The method uses the clustering approach and the teaching-learning-based optimization (TLBO) algorithm. The clustering approach is used to detect CpG island candidates, and it can effectively reduce the huge volume of unnecessary DNA fragments...

Clinical breast examination (CBE) is traditionally taught to third-year medical students using a lecture and a tabletop breast model. The opportunity to clinically practice CBE depends on patient availability and willingness to be examined by students, especially in culturally sensitive environments. We propose the use of a hybrid simulation model consisting of a standardized patient (SP) wearing a silicone breast simulator jacket and hypothesize that this, compared to traditional teaching methods, would result in improved learning...

Autism Spectrum Disorder (ASD) is a highly prevalent neurodevelopmental disorder with enormous individual and social cost. In this paper, a novel virtual reality (VR)-based driving system was introduced to teach driving skills to adolescents with ASD. This driving system is capable of gathering eye gaze, electroencephalography, and peripheral physiology data in addition to driving performance data. The objective of this paper is to fuse multimodal information to measure cognitive load during driving such that driving tasks can be individualized for optimal skill learning...

In many countries, there has been a considerable shift towards providing a more woman-centred maternity service, which affords greater consumer choice. Maternity service provision in Ireland is set to follow this trend with policymakers committed to improving maternal choice at hospital level. However, women's preferences for maternity care are unknown, as is the expected demand for new services. In this paper, we used a discrete choice experiment (DCE) to (1) investigate women's strengths of preference for different features of maternity care; (2) predict market uptake for consultant- and midwifery-led care, and a hybrid model of care called the Domiciliary In and Out of Hospital Care scheme; and (3) calculate the welfare change arising from the provision of these services...

The use of fluoroscopic devices exposes patients and operators to harmful effects of ionizing radiation in an electrophysiology (EP) lab. We sought to know if the newer fluoroscopic technology (Allura Clarity) installed in a hybrid EP helps to reduce prescribed radiation dose. We performed radiation dose analysis of 90 patients who underwent various procedures in the EP lab at a community teaching hospital after the introduction of newer fluoroscopic technology in June of 2016. Watchman device insertion, radiofrequency ablation procedures, permanent pacemaker (PPM)/implantable cardioverter defibrillator (ICD) placement and battery changes were included in the study to compare radiation exposure during different procedures performed commonly in an EP lab...

BACKGROUND: Extranodal NK/T-cell lymphoma (ENKTCL) reports from sub-Saharan Africa (SSA) are remarkably rare, despite early childhood acquisition and high prevalence of the causative infectious agent, Epstein-Barr virus (EBV), and frequent occurrence of other lymphoproliferative disorders causally associated with EBV. CASE PRESENTATIONS: At a national teaching hospital in Malawi, three patients of African descent were seen with ENKTCL between 2013 and 2014. Patients were aged between 29 and 60 years, two with craniofacial involvement and one with a primary abdominal tumor, and all were HIV-negative...

AIM: To investigate the positive rate and types of cells that express Epstein-Barr virus-encoded small RNAs (EBERs) and to determine the distribution of EBER-expressing cells in idiopathic orbital inflammatory pseudotumor (IOIP) tissues. METHODS: We retrospectively examined 40 archived paraffin specimens from two teaching hospitals in Southern China between January 2007 and January 2015 that were pathologically determined to exhibit IOIP. Eleven concurrent paraffin specimens of thyroid-associated ophthalmopathy (TAO) composed the control group...

BACKGROUND: The goal of problem-based and team-based learning (PBL/TBL) is to maximize student engagement and encourage interactive learning. Combining these methods in course design is described as a win-win situation that optimizes student learning, professional development, and uses varied teaching approaches that fit well within health science. More research is needed in the effectiveness of such a hybrid approach. OBJECTIVES: The aim of this study was to explore student experiences of a newly developed mental health course based on an integrated application of PBL and TBL in a university occupational therapy program in Sweden...

Online education as a teaching methodology is relatively new in higher education in comparison to traditional face-to-face instruction. There is often concern that the quality of online classes is inferior and that academic rigor is compromised when faculty are not engaged with students in a classroom. The purpose of this pilot study was to assess nursing faculty attitudes and practices regarding online teaching. Findings indicated that overall, faculty feel that achievement of student learning outcomes in online and hybrid settings is comparable to face-to-face and report excitement with most aspects of teaching online...
