Benjamin Bloom published his Taxonomy of Educational Objectives: Handbook I: Cognitive Domain in 1956 (New York: David McKay, Co.) to help educators develop learning objectives for teaching. Several modifications have been made since then to adapt Bloom's taxonomy to various uses and disciplines (Crowe A, Dirks C, Wenderoth MP. CBE Life Sci Educ 7: 368-381, 2008; Orgill BD, Nolin J. StatPearls. Treasure Island, FL: StatPearls Publishing, 2023; Thompson AR, O'Loughlin VD. Anat Sci Educ 8: 493-501, 2015). In terms of the "Introduction of the Idea," as social constructivist educators, the authors of this article felt the need to adjust Bloom's taxonomy to match the unique characteristics of team-based learning (TBL) in physiology courses. In terms of "Outcomes," we are introducing the use of TBL for teaching physiology in undergraduate and graduate physiology courses that could be easily translated into other disciplines. Additionally, we are introducing the Diamond Framework for TBL, a modified Bloom's taxonomy to match the unique characteristics of TBL and to guide the writing of measurable learning outcomes and assignments.NEW & NOTEWORTHY Team-based learning (TBL) has gained popularity as an educational framework that facilitates teaching conceptual and procedural subjects. However, this technique is less popular among physiology and biomedical sciences. Here, we describe a step-by-step guide for incorporating this learning approach for physiology. Further, we created the Diamond Framework for TBL, a visual taxonomy inspired by Bloom's taxonomy, designed explicitly for TBL, in which the "application" component is at the core of the diamond.

Introduction: There is limited knowledge on pediatric chest radiograph (pCXR) interpretation skill among practicing physicians. We systematically determined baseline interpretation skill, the number of pCXR cases physicians required complete to achieve a performance benchmark, and which diagnoses posed the greatest diagnostic challenge.

Methods: Physicians interpreted 434 pCXR cases via a web-based platform until they achieved a performance benchmark of 85% accuracy, sensitivity, and specificity. Interpretation difficulty scores for each case were derived by applying one-parameter item response theory to participant data. We compared interpretation difficulty scores across diagnostic categories and described the diagnoses of the 30% most difficult-to-interpret cases.

Results: 240 physicians who practice in one of three geographic areas interpreted cases, yielding 56,833 pCXR case interpretations. The initial diagnostic performance (first 50 cases) of our participants demonstrated an accuracy of 68.9%, sensitivity of 69.4%, and a specificity of 68.4%. The median number of cases completed to achieve the performance benchmark was 102 (interquartile range 69, 176; min, max, 54, 431). Among the 30% most difficult-to-interpret cases, 39.2% were normal pCXR and 32.3% were cases of lobar pneumonia. Cases with a single trauma-related imaging finding, cardiac, hilar, and diaphragmatic pathologies were also among the most challenging.

Discussion: At baseline, practicing physicians misdiagnosed about one-third of pCXR and there was up to an eight-fold difference between participants in number of cases completed to achieve the standardized performance benchmark. We also identified the diagnoses with the greatest potential for educational intervention.

For decades, language and literacy scholars working within a sociocultural framework have laboured to bring attention to the strengths of marginalized students in an effort to create more inclusive and equitable learning environments (e.g., Cummins, 2000; Dyson, 1997; González et al., 2005; Heath, 1983). While this work has moved the field forward in invaluable ways, it has not consistently engaged with processes of marginalization as a complex practice, which has produced gaps in our understanding of how we can best address it in research and practice to the benefit of all learners. Drawing on the notions of literacy socialization (Sterponi, 2012) and syncretic literacy (Duranti and Ochs, 1996; Gregory et al., 2013a), in this paper I conduct a close examination of the in- and out-of-school literacy socialization practices of Max Calfu, a seven-year-old Chilean-Canadian boy, over the course of a year-long ethnography that I conducted with his family at their home, at his Spanish-English bilingual public school, and in transit between home and school in a large Western Canadian city. At school, Max's Indigenous identity was regularly rendered invisible by the cultural capital his Chilean-national heritage held within the Spanish bilingual program (Calderón and Urrieta, 2019). Using thematic analysis (Saldaña, 2013), I demonstrate how Max incorporated the wolf figure into his literacy practices over the course of the research year, considering multiple scales of space and time, and in relation to key mediators. My analysis calls attention to the ways in which he drew on his syncretic literacy experiences to author his Indigenous identity in official and unofficial learning spaces. I conclude the paper by arguing that examining syncretism in children's literacy practices can lay the foundation for a more ethically, emotionally, and culturally engaged language education.

In this article we analyze the classic Hodgkin and Keynes 1955 paper describing investigations of the independence principle, with the expectation that there is much students and educators can learn from such exercises, most notably how the authors applied their diverse skill set to tackling the numerous obstacles that the study presented. The paper encompasses three of the physiology core concepts, cell membranes, flow down gradients, and scientific reasoning, which were recently assigned to the classes The Biological World, The Physical World, and Ways of Looking at the World, respectively. Thus, analysis of such a paper illuminates the relationships that exist between distinct concepts and encourages a holistic approach to understanding physiology. In-depth analysis of the paper allows us to follow the authors' thought processes from their realization that previous methods lacked the resolution to answer a fundamental question relating to ion movement across membranes to the application of a more sensitive technique and ultimately the development of a novel model describing ion flux. This paper was the culmination of work started in the mid-1930s, strongly supported the ionic theory of nervous conduction proposed by Hodgkin and Huxley, and predicted the presence of ion channels as narrow pores through which ions move sequentially four decades before these features were convincingly demonstrated.NEW & NOTEWORTHY We describe in detail Hodgkin and Keynes' investigation of the independence principle. It is our expectation that students and educators can benefit from following the thought processes applied by the authors as they navigated the complexities of experimental design and data analysis, culminating in development of a model whose elegant simplicity was convincing evidence of narrow membrane-bound pores, ion channels, that were the conduit for transmembrane ion movement.

With the increased attention focused on active learning, educators strive to find better and more innovative ways to engage students in the classroom. One of the hurtles that educators are presented with is that the classroom is no longer limited to a physical location but rather students and professor can meet via the internet, Before COVID-19, distance or remote learning was something that students, by and large, had the option of choosing in which whether to engage. Students had the option to take "online courses," whether those be synchronous remote learning or asynchronous online courses. Indeed, numerous studies have focused on investigating the efficacy of many different approaches to distance and online learning. Unfortunately, COVID 19 mandated a rapid transition to remote learning, and with this forced change has come what some students describe as "Zoom fatigue" (Wolf CR. Psychology Today, May 2020). Many students reported feeling exhausted, overwhelmed, and disengaged by the dramatic increase in mandated distance education required by the COVID pandemic. Video conferencing has become the "go-to" panacea for education during this time, and students are spending unprecedented amounts of time in front of a screen when normally they would be in a classroom. This heretofore singular and unique approach to education coupled with decreased peer-to-peer interaction has caused a problem with student engagement (Goodman BE, Barker MK, Cooke JE. Adv Physiol Educ 42: 417-423, 2018). Students' engagement and performance have decreased during COVID-19 because of forced online learning and lack of peer interaction. We hypothesize that creating a nongraded, fun, and relaxing physiology-focused "Trivia Night" will increase student engagement and performance on summative assessments. Using a master's level class progressing through the respiratory physiology module utilizing remote, synchronous lectures to deliver content, we introduced a voluntary Trivia Night review session with teams randomly assigned to increase interaction among peers and review respiratory physiology material.NEW & NOTEWORTHY This article presents the effectiveness of the use of the "pub Trivia Night" to facilitate learning, deconstruct misconceptions, and increase engagement during remote teaching due to the COVID-19 pandemic.

The expression excitation-contraction (EC) coupling in skeletal muscle was coined in 1952 (Sandow A. Yale J Biol Med 25: 176-201, 1952). The term evolved narrowly to include only the processes at the triad that intervene between depolarization of the transverse tubular (T-tubular) membrane and Ca²⁺ release from the sarcoplasmic reticulum (SR). From 1970 to 1988, the foundation of EC coupling was elucidated. The channel through which Ca²⁺ was released during activation was located in the SR by its specific binding to the plant insecticide ryanodine. This channel was called the ryanodine receptor (RyR). The RyR contained four subunits that together constituted the "SR foot" structure that traversed the gap between the SR and the T-tubular membrane. Ca²⁺ channels, also called dihydropyridine receptors (DHPRs), were located in the T-tubular membrane at the triadic junction and shown to be essential for EC coupling. There was a precise relationship between the two channels. Four DHPRs, organized as tetrads, were superimposed on alternate RyRs. This structure was consistent with the proposal that EC coupling was mediated via a movement of intramembrane charge in the T-tubular system. The speculation was that the DHPR acted as a voltage sensor transferring information to the RyRs of the SR by protein-protein interaction causing the release of Ca²⁺ from the SR. A great deal of progress was made by 1988 toward understanding EC coupling. However, the ultimate question of how voltage sensing is coupled to the opening of the SR Ca²⁺ release channel remains unresolved.NEW & NOTEWORTHY The least understood part of the series of events in excitation-contraction coupling in skeletal muscle was how information was transmitted from the transverse tubules to the sarcoplasmic (SR) and how Ca²⁺ was released from the SR. Through an explosion of technical approaches including physiological, biochemical, structural, pharmacological, and molecular genetics, much was discovered between 1970 and 1988. By the end of 1988, the foundation of EC coupling in skeletal muscle was established.

Introduction: Evidence links assessment to optimal learning, affirming that physicians are more likely to study, learn, and practice skills when some form of consequence ("stakes") may result from an assessment. We lack evidence, however, on how physicians' confidence in their knowledge relates to performance on assessments, and whether this varies based on the stakes of the assessment.

Methods: Our retrospective repeated-measures design compared differences in patterns of physician answer accuracy and answer confidence among physicians participating in both a high-stakes and a low-stakes longitudinal assessment of the American Board of Family Medicine.

Results: After 1 and 2 years, participants were more often correct but less confident in their accuracy on a higher-stakes longitudinal knowledge assessment compared with a lower-stakes assessment. There were no differences in question difficulty between the two platforms. Variation existed between platforms in time spent answering questions, use of resources to answer questions, and perceived question relevance to practice.

Discussion: This novel study of physician certification suggests that the accuracy of physician performance increases with higher stakes, even as self-reported confidence in their knowledge declines. It suggests that physicians may be more engaged in higher-stakes compared with lower-stakes assessments. With medical knowledge growing exponentially, these analyses provide an example of the complementary roles of higher- and lower-stakes knowledge assessment in supporting physician learning during continuing specialty board certification.

Cell therapies have gained prominence as a promising therapeutic modality for treating a range of diseases. Despite the recent clinical successes of cell therapy products, very few formal training programs exist for cell therapy manufacturing. To meet the demand for a well-trained workforce, we assembled a team of university researchers and industry professionals to develop an online course on the principles and practice of cell therapy manufacturing. The course covers the basic cell and systems physiology underlying cell therapy products, in addition to explaining end-to-end manufacturing from cell acquisition through to patient treatment, industrialization, and regulatory processes. As of September 2023, >10,000 learners have enrolled in the course, and >90% of respondents to the course exit survey indicated that they were "very likely" or "likely" to recommend the course to a peer. In this article, we discuss our experience in the collaborative design and implementation of the online course as well as lessons learned from quantitative and qualitative student feedback. We believe that this course can serve as a model for how academia and industry can collaborate to create innovative, scalable training programs to meet the demands of the modern biotechnology workforce.NEW & NOTEWORTHY We assembled a team of university researchers and industry professionals to develop an online course on the principles and practice of cell therapy manufacturing.

Introduction: Comprehending scientific information have been reported as a barrier in evidence-based practice (EBP) adoption. This survey research aimed to verify the preferred sources of information for acquiring knowledge about physiotherapy and the association between types of information source and barriers in EBP implementation.

Methods: A total of 610 physiotherapists were included and answered an online questionnaire about the preferred sources for searching physiotherapy-related information and possible barriers in EBP implementation.

Results: Physiotherapists reported scientific resources as the preferred source of information, scientific databases (31%), followed by scientific articles (25%). The main barrier cited in EBP implementation was the difficulty in obtaining full-text articles (34%), followed by lack of statistical knowledge (30%). The use of peer-reviewed resources as the most preferred source of information is associated with the presence of issues in comprehending scientific information.

Discussion: Although the positive attitude toward the use of scientific information, the findings raised question regarding the proper translation of scientific information to clinical practice. The importance of scientific information seems to be a well-established attitude among physiotherapists. However, there is a clear need for strategies aiming to improve the understanding of scientific information and consequently facilitate EBP implementation.
