Mainstreaming the Hearing Impaired Student‐‐An Area of Preparation Responsibility for Teacher Training Programs: A Pilot Study     

Harold A. Johnson  Penny L. Griffith 《International Journal of Disability, Development & Education》1985,32(3):185-190

Interviewing, as an information‐gathering tool for prospective teachers of the deaf, was used to document the perspectives which deaf children, their parents, teachers and administrators bring to the mainstreaming process. Data revealed the different, and sometimes competing priorities of mainstreaming participants; these priorities are discussed in terms of their impact upon the success or failure of the mainstreaming process and the preparation responsibilities of teacher training programs.  相似文献

Transport and shear in a microfluidic membrane bilayer device for cell culture     

Inamdar NK  Griffith LG  Borenstein JT 《Biomicrofluidics》2011,5(2):22213

Microfluidic devices have been established as useful platforms for cell culture for a broad range of applications, but challenges associated with controlling gradients of oxygen and other soluble factors and hemodynamic shear forces in small, confined channels have emerged. For instance, simple microfluidic constructs comprising a single cell culture compartment in a dynamic flow condition must handle tradeoffs between sustaining oxygen delivery and limiting hemodynamic shear forces imparted to the cells. These tradeoffs present significant difficulties in the culture of mesenchymal stem cells (MSCs), where shear is known to regulate signaling, proliferation, and expression. Several approaches designed to shield cells in microfluidic devices from excessive shear while maintaining sufficient oxygen concentrations and transport have been reported. Here we present the relationship between oxygen transport and shear in a "membrane bilayer" microfluidic device, in which soluble factors are delivered to a cell population by means of flow through a proximate channel separated from the culture channel by a membrane. We present an analytical model that describes the characteristics of this device and its ability to independently modulate oxygen delivery and hemodynamic shear imparted to the cultured cells. This bilayer configuration provides a more uniform oxygen concentration profile that is possible in a single-channel system, and it enables independent tuning of oxygen transport and shear parameters to meet requirements for MSCs and other cells known to be sensitive to hemodynamic shear stresses.  相似文献   

Promoting Metacognitive Decision-Making in Teacher Education     

Robin Griffith  Michelle Bauml  Sarah Quebec-Fuentes 《理论付诸实践》2016,55(3):242-249

Effective teachers are characterized by their abilities to make thoughtful, deliberate, and informed adaptations while teaching (Hoffman & Pearson, 2000). These in-the-moment teaching decisions are guided by a complex web of teacher knowledge. Raising teachers' awareness of the decisions they make on a moment-by-moment basis may aid in thoughtful, more deliberate decision-making and more robust instruction. We charge that preservice teachers can acquire this skill, as well. This article highlights practices employed in preservice teacher education courses as a means to promote awareness of, and engagement with, in-the-moment teaching decisions. Using examples from mathematics, social studies, and literacy methods courses, we describe our processes to intentionally cultivate preservice teachers' adaptive teaching skills through metacognitive decision-making.  相似文献   

Teaching evolutionary biology: Pressures,stress, and coping     

Joyce A. Griffith  Sarah K. Brem 《科学教学研究杂志》2004,41(8):791-809

Understanding what teachers need to be more comfortable and confident in their profession is crucial to the future of effective teachers and scientific literacy in public schools. This study focuses on the experiences of Arizona biology teachers in teaching evolution, using a clinical model of stress to identify sources of pressure, the resulting stresses, and coping strategies they employ to alleviate these stresses. We conducted focus groups, one‐on‐one interviews, and written surveys with 15 biology teachers from the Phoenix area. On the basis of their responses, teachers were clustered into three categories: “Conflicted,” who struggle with their own beliefs and the possible impact of their teaching, “Selective,” who carefully avoid difficult topics and situations, and “Scientists,” who see no place for controversial social issues in their science classroom. Teachers from each group felt that they could be more effective in teaching evolution if they possessed the most up‐to‐date information about evolution and genomics, a safe space in which to reflect on the possible social and personal implications with their peers, and access to richer lesson plans for teaching evolution that include not only science but personal stories regarding how the lessons arose, and what problems and opportunities they created. © 2004 Wiley Periodicals, Inc.

Developing Student Metacognition through Reflective Writing in an Upper Level Undergraduate Anatomy Course     

Valerie Dean O’Loughlin  Lauren Miller Griffith 《Anatomical sciences education》2020,13(6):680-693

Incorporating metacognitive strategies in the classroom helps students monitor and adjust their learning strategies throughout the semester, and helps students progress from novice to expert learners in a subject. Journaling (i.e., reflective writing) is one metacognitive task that allows students to contemplate and articulate their skill development as they learn a new subject. The research reported here examines the use of ‘blogs’ (i.e., online journals) in an upper level undergraduate human anatomy course. The blogs both facilitated development of students' metacognitive skills and provided researchers insight into student metacognitive process. Data were examined from 92 students from three successive semesters (spring 2010, 2012 and 2014). Each student reviewed 10 radiology online cases throughout the semester and then reflected on their understanding of anatomy and radiology in an online blog for each case. A total of 927 blogs were examined for this research. The researchers used a grounded theory approach to analyze the blog narratives and develop a codebook based on common themes. The 927 blogs yielded 11,082 statements that were coded with the codebook. As the semester progressed, the blog entries showed that students demonstrated greater self-confidence in their abilities to understand the subject matter, expressed greater enthusiasm for anatomy in general, and they improved their metacognitive skills. This research illustrates that reflective writing in an undergraduate anatomy course not only facilitates improvement in student metacognitive skills, but also provides the instructor with evidence how a student progresses from novice to more experienced learner in anatomy.  相似文献

The use and misuse of primary sources: The editing of Collingwood's manuscripts     

Bryant Griffith 《Interchange》1992,23(4):419-429

This article examines many of Collingwood's unpublished papers and their relationships toThe Idea of History. An assessment of the role of Collingwood's editor, T. M. Knox, is also made in an effort to establish accurately Collingwood's reputation as an historiographer. The author also argues that all of the unpublished papers should be released for publication, and that a new edition ofThe Idea of History should be published.  相似文献
