Preservice teachers' in‐the‐moment teaching decisions in reading          下载免费PDF全文

《Literacy》2017,51(1):3-10

This study examines the types of in‐the‐moment teaching decisions 97 preservice teachers made while teaching reading and how their growing bodies of teacher knowledge influenced their abilities to think, know, feel and act like a teacher (Feiman‐Nemser, 2008 ). Findings indicated that the teacher educator's use of “metacognitive decision‐making” to promote a culture of identifying, drawing attention to, reflecting on and evaluating teaching decisions influenced the preservice teachers' abilities to think, know, feel and act like a teacher. These findings have implications for teacher education and for those who support novice teachers.  相似文献

A qualitative inquiry of doctoral students' herding in education and validation of ‘herding in educational decisions’ scale     

Muhammad Ali Asadullah  Sumaira Mirza  Muhammad Zia Ul Haq  Tahir Yaqoob  Sajid Hussain 《Higher Education Quarterly》2023,77(1):102-120

Fresh PhD recipients are experiencing restricted career opportunities yet the enrolment of PhD Scholars is increasing rapidly. Perhaps, doctoral students lack conscious educational decision-making. Building on such a perspective of doctoral students' unconscious educational choices, we explored their educational choices throughout their life trajectory. We started with a qualitative inquiry of 18 different PhD scholars in Pakistan. The findings helped us in developing a measure to determine the extent of herding in doctoral students' educational decisions. We ‘benefitted from’ this opportunity and validated the scale in two separate quantitative inquiries for conducting an exploratory factor analysis and confirmatory factor analysis. The study concluded a 3-dimensional scale (consisting of 15-items) for measuring ‘herding in educational decisions’. The study offers certain implications for conscious educational decisions.  相似文献

宋淑英  马国东 《天津体育学院学报》2011,26(4):287-289

短道速滑比赛过程紧张而激烈,在不同临场决策,如启动加速、领滑、跟随滑行、超越、配合等技战术的运用和发挥时,都需要运动员对周围 环境进行观察判断。视觉信息提取的不同模式可准确反映出运动员在比赛中不同临场情境时采取不同技、战术策略。因此,记录短道速滑运动员 在运动训练或比赛过程中不同临场决策的眼动模式,有利于提供有效训练的模式和策略。  相似文献

Factors affecting placement decisions of children following short-term emergency care     

Uma A. Segal Ph.D.  Sanford Schwartz Ph.D. 《Child abuse & neglect》1985,9(4):543-548

Case files of 424 residents at an emergency treatment center for abused and neglected children were used to generate a beginning set of variables which, in combination, predicted whether or not children from the center would be discharged to their natural family environment. Variables with descending order of predictive significance were place from which the child was admitted, the length of time spent in treatment, the age and the race of the child, Other variables--the number of siblings, the child's sex and the presence of physical/sexual abuse--did not approach significance.  相似文献

Career development of English female head-teachers: influences,decisions and perceptions     

Ewa McKillop 《School Leadership & Management》2017,37(4):334-353

This paper presents findings from a study examining the career development experiences of female head-teachers in the south of England. Adapting a three-stage career model, the study examined different stages of the women’s lives and careers in order to understand what encouraged and influenced them to become educational leaders and how their experiences shaped their perceptions of headship. The study used semi-structured life story interviews to generate rich accounts of women’s lives from childhood. Findings suggest that parents exerted significant influence on the participants’ values and ambitions, while teachers influenced their career choices. Their perceptions of headship developed and changed over time, transforming from feelings of shock at the reality and the complexity of headship to control and confidence that increased over first, second and third headships.  相似文献   

Do Proper Accommodation Assignments Make a Difference? Examining the Impact of Improved Decision Making on Scores for English Language Learners   总被引：1，自引：0，他引：1  

Rebecca J. Kopriva  Jessica E. Emick  Carlos Porfirio Hipolito-Delgado  Catherine A. Cameron 《Educational Measurement》2007,26(3):11-20

Does it matter if students are appropriately assigned to test accommodations? Using a randomized method, this study found that individual students assigned accommodations keyed to their particular needs were significantly more efficacious for English language learners (ELLs) and that little difference was reported between students receiving incomplete or not recommended accommodations and no accommodations whatsoever. A sample of third and fourth grade ELLs in South Carolina (N = 272) were randomly assigned to various types of test accommodations on a mathematics assessment. Results indicated that those students who received the appropriate test accommodations, as recommended by a version of a computerized accommodation taxonomy for ELLs (the selection taxonomy for English language learners accommodations; STELLA), had significantly higher test scores than ELLs who received no accommodations or those who received incomplete or not recommended accommodation packages. Additionally, students who were given no test accommodations scored no differently than those students that received accommodation packages that were incomplete or not recommended, given the students' particular needs and challenges. These findings are important in light of research and anecdotal reports that suggest a general lack of systematicity in the current system of assigning accommodations and a tendency to give all available accommodations regardless of individual child characteristics. The results also have important implications for how future accommodation research should be structured to determine the benefits of particular accommodations and accommodation packages. This study would suggest that control and treatment groups should be assembled based on specific student needs in order for direct comparisons to be made.  相似文献
