Pharmacokinetic Models for Active Learning of Differential Equations     

Therese Shelton  Theresa Laurent  Beulah Agyemang-Barimah 《PRIMUS》2019,29(7):742-767

Abstract

We present adaptable activities for models of drug movement in the human body – pharmacokinetics – that motivate the learning of ordinary differential equations with an interdisciplinary topic. Specifically, we model aspirin, caffeine, and digoxin. We discuss the pedagogy of guiding students to understand, develop, and analyze models, progressing in complexity to a system of differential equations. We investigate the effects of parameter values that distinguish various health levels, and dosing that may have toxic effects. Our assignments include modeling in a student-centered, active, and increasingly inquiry-oriented setting through which the mathematics and biology inform and reinforce each other. We include supplemental information regarding inquiry methods, student learning outcomes, a student’s commentary about our activities, and support through mathematical communities such as POGIL and SIMIODE.  相似文献

Pre-service teachers’ empathy and cognitions: Statistical analysis of text data by graphical models     

Sharon Tettegah  Carolyn J. Anderson 《Contemporary educational psychology》2007

This research examines empathic dispositions of 178 pre-service teachers. We analyzed open ended responses to animated narrative vignette simulations (ANVs), which served as stimulated experimental situations depicting students in victim and perpetrator scenarios. Empathy was examined by addressing the following questions: (1) Do participants’ responses differ over vignettes? (2) What is the dimensionality of the empathy construct? (3) Is word count an indicator of empathy? (4) Is there a dispositional effect? (5) To what extent do pre-service teachers express empathy? After the text responses of pre-service teachers were coded, log-linear and log-multiplicative association models, which have graphical representations, were used to analyze the data and to develop a context dependent measure of empathy. The results suggest that a single latent variable underlies the responses, and from our measurement model, very few teachers expressed empathy toward the victim in the ANVs.  相似文献   

Science education II: Scientific literacy and the Karplus taxonomy     

Pollak  Victor L. 《Journal of Science Education and Technology》1994,3(2):89-97

In this essay we explore the role played by the conceptual structure of science in scientific literacy. It is shown that the taxonomy of scientific concepts elucidated by Karplus is a basic structural characteristic of science, and provides a natural means forengaging, as distinct from merely learning, scientific content. Special attention is given to the idea scientific model as being fundamental to the discipline and therefore essential to scientific literacy. The relationship between scientific models and common misconceptions is developed.Based on the second of two talks given at the Paedagogische Hochschule, Ludwigsburg, Germany, in November 1988.  相似文献   

Examining the Short-, Medium-, and Long-Term Success of an Embodied Learning Activity in the Study of Hand Anatomy for Clinical Application     

Lillian Smyth  James Carter  Krisztina Valter  Alexandra L. Webb 《Anatomical sciences education》2021,14(2):201-209

A student's own body provides an often disregarded site of knowledge production and corporeal wisdom. Learning via cognitive processes anchored in physical movement and body awareness, known as embodied learning, may aid students to visualize structures and understand their functions and clinical relevance. Working from an embodied learning perspective, the current article evaluates the use of an offline physical learning tool (Anatomical Glove Learning System; AGLS) for teaching hand anatomy for clinical application in medical students. Two student samples (N₁ = 105; N₂ = 94) used the AGLS in two different ways. In the first sample, the AGLS was compared to a traditional approach using hand bones, models and prosected specimens. Secondly, the AGLS and traditional approach were combined. The evaluation consisted of three outcomes: short-term learning (post-test), medium-term applications (mock-objective structured clinical examination, MOSCE), and longer-term assessment (objective structured clinical examination, OSCE). Findings from the first sample indicated no significant differences between the AGLS and traditional laboratory groups on short- (F_(1,78) = 0.036, P = 0.849), medium- (F_(1,50) = 0.743, P = 0.393), or longer-term (F_(1,82) = 0.997, P = 0.321) outcomes. In the second sample using the AGLS in combination with a traditional approach was associated with significantly better short-term post-test scores (F_(2,174) = 5.98, P = 0.003) than using the AGLS alone, but demonstrated no effect for long-term OSCE scores. These results suggest an embodied learning experience alone does not appear to be advantageous to student learning, but when combined with other methods for studying anatomy there are learning gains.  相似文献

毒品犯罪立法例中的理论问题评介——以大陆法系国家（地区）为视角     

张理恒 《成都师专学报》2008,(6):68-72

对于毒品犯罪的立法例,大陆法系诸国（地区）采用了分散型模式,使得各类型罪状明确具体,罚当其罪。这更有利于反思我国现有的毒品犯罪立法模式。基于分散型的立法倾向,复数的法律适用根据在同一事案上发生竞合现象时,原则上重法优于全部法适用、全部法优于特别法适用。对毒品种类发生认识错误的,在构成要件间重合的范围内成立轻罪的既遂犯;但是,主客观事实所涉及的同质构成要件无刑罚差别时,成立现实发生事实的故意犯罪。  相似文献   

一类改进的PDE模型在图像去噪和分割中的应用     

吴伟  崔尚斌  王颖 《临沂师范学院学报》2008,30(6)

利用变分原理研究了图像能量泛函的极小值问题所对应的一类改进的偏微分（PDE）模型．通过对偏微分方程的研究,从形式上分析得到方程的解即结果图像,在去噪后与初始图像有较小的偏差,很好地保持了初始图像所具有的特征．实验结果验证了这种分析结果的正确性,并且得到在去噪时间相同的条件下,结果图像要比以往的模型较好．在分割处理上,结果图像也有较好的分割效果．  相似文献   

A statewide writing assessment model: Student proficiency and future implications     

Leon  Jody  Sue 《Assessing Writing》2008,13(1):45-60

This paper is an examination of statewide district writing achievement gain data from the Nebraska Statewide Writing Assessment system and implications for statewide assessment writing models. The writing assessment program is used to gain compliance with the United States No Child Left Behind Law (NCLB), a federal effort to influence school district assessment and accountability. While the research literature is mixed with some viewing statewide writing assessment as narrowing writing curriculum and “standardizing” writing, others point out that it facilitates sharing between teachers to improve writing and teachers are empowered by their participation in the process.Nebraska's Statewide Writing Assessment, based on the six-trait model, has strong support from teachers regarding their perception of the assessment in supporting teaching practices and student success. Examination of achievement gain data revealed gains in 4th, 8th, and 11th grades in the average number of students rated proficient from one administration of the assessment to the next.Implications for educational practice, recommendations for future research, and relevant related issues (NCLB concerns and measurement issues) are discussed.  相似文献
