Diversity Knowledge in Science Teacher Education-Translating Concept to Instruction: An Example Specific to African Americans

Science education reforms promote access to quality science education for all students. Outcome disparities in various measures indicate that such access remains elusive for African Americans. Cultural incongruence is one among many explanations for this previously described inaccessibility. The intent of this article is not to report additional research findings, but to translate the information provided in the literature into an instructional form that science teacher educators can employ in the preparation of prospective science teachers or the further development of practicing ones. Pivoting around a role play, the authors discuss communication within African American communities, its incongruence with the discourse patterns typically valued and reinforced in school science, and the importance of such knowledge for science teacher educators. Lieutenant Colonel Stephanie Foster is now product manager in the U.S. Army Research Development and Engineering Command.

Development and reliability of the comprehensive crisis plan checklist

It is of vital importance that children are educated in a safe environment. Every school needs to have a well‐developed crisis management document containing plans for prevention, intervention, and postvention. We developed the Comprehensive Crisis Plan Checklist (CCPC) to serve as a valuable tool that can be used to assist practitioners with evaluation of their school crisis management plans. To use the CCPC, school personnel should match the items on the checklist to elements in their developing or existing crisis plan to determine missing elements. By comparing a school or district crisis plan to the CCPC, practitioners or school personnel will be able to determine strengths and weaknesses of the plan as well as provide feedback for making their plans more complete and comprehensive. In this study, we describe the development of the CCPC and report on reliability data using this checklist. © 2010 Wiley Periodicals, Inc.     

Crashing from cadaver to computer: Covid-driven crisis-mode pedagogy spawns active online substitute for teaching gross anatomy

In early 2020, the Covid-19 crisis forced medical institutions worldwide to convert quickly to online platforms for content delivery. Although many components of medical education were adaptable to that format, anatomical dissection laboratory lost substantial content in that conversion, including features of active student participation, three-dimensional spatial relationships of structures, and the perception of texture, variation, and scale. The present study aimed to develop and assess online anatomy laboratory sessions that sought to preserve benefits of the dissection experience for first-year medical students. The online teaching package was based on a novel form of active videography that emulates eye movement patterns that occur during processes of visual identification, scene analysis, and learning. Using this video-image library of dissected materials, content was presented through asynchronous narrated laboratory demonstrations and synchronous/active video conference sessions and included a novel, video-based assessment tool. Data were obtained using summative assessments and a final course evaluation. Test scores for the online practical examination were significantly improved over those for previous in-person dissection-based examinations, as evidenced by several measures of performance (Mean: 2015–2019: 82.5%; 2020: 94.9%; P = 0.003). Concurrently, didactic test scores were slightly, but not significantly, improved (Mean: 2015–2019: 88.0%; 2020: 89.9%). Student evaluations of online sessions and overall course were highly positive. Results indicated that this innovative online teaching package can provide an effective alternative when in-person dissection laboratory is unavailable. Although this approach consumed considerable faculty time for video editing, further development will include video conference breakout rooms to emulate dissection small-group teamwork.     

倾向得分法及其在科技工作者自我效能认知研究中的应用

因果推论背景下的倾向得分法是近年在国外发展起来的重要因果分析方法,是排除背景变量混杂干扰,通过模拟随机抽样,使用抽样调查数据计算干预效果的有效方法.采用天津市科技工作者实际工作状况调查的抽样数据,使用倾向得分法测算薪酬、专业技术职级、行政职级对于自我成就感的影响,从而验证传统激励措施对于自我效能认知的提升作用,以及对于科技人才开发管理的促进作用.应用倾向得分法模拟随机抽样后,薪酬对于天津市科技工作者的自我效能认知具有显著影响,专业技术职级的作用不再显著,而行政职级的作用则显示出显著相关.     

Fostering Intrinsic Motivation in Early Childhood Classrooms

Young children are born with an innate curiosity to learn about their world. This intrinsically instigated learning is often called mastery motivation. Patterns of motivation are established at an early age. The early childhood years are crucial for establishing robust intrinsic motivational orientations which will last a lifetime. By the time many children reach school, much of their motivation has been lost or replaced with extrinsically motivated learning strategies. Preschools and elementary schools have been criticized for contributing to such negative motivational patterns in children. This can be changed. Early child care situations and preschools can instead be instrumental in the strengthening of children's motivation. The goal of this paper is to show that through an understanding of the beginnings of motivation, we can begin to find ways to build strong motivational patterns in children that can carry on to later years of learning.     

Estimating changes in hydration status from changes in body mass: considerations regarding metabolic water and glycogen storage

The potential for imprecision in the estimation of hydration status from changes in body mass has been outlined previously but the equations derived from these derivations appear inconsistent. Reconciliation of body mass loss in terms of sweat loss and effective body water loss is possible from specific equation sets provided that gains and losses of both body mass and water used in the derivation of sweat loss and to derive effective body water loss are in inclusive equation sets. This is obligatory so that mass and water changes as quantifiable determinants are consistent with both internal processes and external gains and losses. Thus, body mass loss, substrate oxidation, metabolic water, and all the terms used in simultaneous equation sets have to be reconciled not only as identical variables but mathematically balance exactly. The revised equation for effective body water loss given here is different from that originally proposed. Metabolic water is part of body mass loss corrected for substrate oxidation, fluid ingestion, and respiratory water to derive sweat loss and it may not be justified to also include water associated with glycogen as releasable bound water. Accordingly, our calculated effective body water loss is substantially a greater loss than originally supposed but clearly still less than the simple balance between mass loss and fluid ingested.
