Systems modeling, a cognitive tool, allows students to visualize their mental model of the problem space to enhance learning and retention. We performed a within-subjects three-period randomized control comparison of systems modeling versus written discussion activities in an undergraduate asynchronous online Anatomy and Physiology II course. Participants (<i>n</i> = 108) were randomized to groups with differing treatment orders across three course units: endocrine, immune, and acid-base balance. Participants demonstrated content understanding through either constructing systems modeling diagrams (M) or written discussion posts (W) in a MWM, MMW, or WMM sequence. For each of three units, student performance was assessed on 6 standardized multiple-choice questions embedded within a 45-question exam. The same 6 questions per unit, 18 questions in total, were again assessed on the 75-question final exam. The groups demonstrated no significant difference in performance in the endocrine unit exam [mean difference (MD) = -0.036]. However, the modeling group outperformed the writing group in the immune unit exam (MD = 0.209) and widened the gap in the acid-base balance unit exam (MD = 0.243). On the final exam, performance was again higher for the modeling group on acid-base balance content, as mean difference increased to 0.306 despite the final exam content for acid-base balance being significantly more difficult compared to other units [modeling: <i>F</i>(2) = 29.882, <i>P</i> < 0.001; writing: <i>F</i>(2) = 25.450, <i>P</i> < 0.001].

Therefore, developing a physiologically sound educational model to demonstrate these forces can significantly enhance the learning experience for students, providing them with a clear and comprehensive understanding of renal filtration. Starling forces include the glomerular capillary hydrostatic pressure, which drives plasma filtration; the plasma colloid osmotic pressure (also referred to as the oncotic pressure within the capillary), which opposes filtration; and the Bowman's capsule hydrostatic pressure, which resists fluid influx. Bowman's capsule oncotic pressure is typically considered negligible in healthy kidneys and, therefore, does not usually influence the glomerular filtration process. It is crucial for future clinicians to understand these Starling forces in order to monitor and manage kidney function effectively. To aid in understanding these concepts, we present a simple yet effective physical model of GFR. This model uses pressurized air and a serological pipette setup to simulate the filtration process, with a ping-pong ball's height representing GFR. Various perturbations demonstrate changes in Starling forces, allowing students to visualize the impact of different physiological and pathological conditions on GFR.

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. <i>Adv Physiol Educ</i> 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.<b>NEW & NOTEWORTHY</b> 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.</p>","PeriodicalId":50852,"journal":{"name":"Advances in Physiology Education","volume":" ","pages":"720-725"},"PeriodicalIF":1.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141908251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.<b>NEW & NOTEWORTHY</b> 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.

Many nonanatomists may thus believe that studying anatomy does not develop transferable higher-order cognitive skills.
