A Bayesian Method for Evaluating Passing Scores: The PPoP Curve     

Howard Wainer  X. A. Wang  William P. Skorupski  Eric T. Bradlow 《Journal of Educational Measurement》2005,42(3):271-281

In this note, we demonstrate an interesting use of the posterior distributions (and corresponding posterior samples of proficiency) that are yielded by fitting a fully Bayesian test scoring model to a complex assessment. Specifically, we examine the efficacy of the test in combination with the specific passing score that was chosen through expert judgment, or, in general, any external a priori criterion. In addition, we study the robustness of the test's efficacy with respect to choice of the passing score.  相似文献   

Extinction revisited: Similarities between extinction and reductions in US intensity in classical conditioning of the rabbit’s nictitating membrane response     

E.?James?KehoeEmail author  Natasha?E.?white 《Learning & behavior》2002,30(2):96-111

The mechanisms of extinction were examined by reducing the intensity of the unconditioned stimulus (US) after acquisition training to determine whether such reductions lie on a continuum with CS-alone extinction. The experiments revealed that reductions in US intensity yielded extinction-like effects. Specifically, there were proportional reductions in the daily mean level of responding across sessions. There were also persistent within-session declines and between-session increases of responding analogous to spontaneous recovery. Surprisingly, even when US intensity was held constant, within-session declines and between-session increases were apparent. The results are discussed with respect to possible contributions from unlearning, new learning, generalization decrement, and nonassociative loss, especially CS-specific attentional changes and CR-specific reactive inhibition.  相似文献

The necessity of each phase of the learning cycle in teaching high school physics     

John W. Renner  Michael R. Abraham  Howard H. Birnie 《科学教学研究杂志》1988,25(1):39-58

The learning cycle is a method of teaching—it is also a curriculum organization principle and is derived directly from the mental functioning model invented by Piaget. Although Jean Piaget contributed to the formation of the learning cycle (Piaget, 1973), its present structure has to be attributed to Dr. Robert Karplus and the persons who developed the materials of the Science Curriculum Improvement Study (SCIS). It was through the SCIS activities that many of us learned how to develop curricula and teach with the learning cycle. The learning cycle is built upon the premise that three distinct phases are necessary in developing understanding of a concept, that those phases have a definite sequence, and each phase has a definite structure or form. The research done in testing the form variable has already been reported in this journal (Renner, Abraham, & Birnie, 1985). This report explores whether or not each learning-cycle phase is necessary in learning a concept.  相似文献   

A Process Approach to Community-Based Education: The People’s Free University of Saskatchewan     

Howard Woodhouse 《Interchange》2005,36(1-2):121-138

On the basis of insights provided by Whitehead and John Cobb, I show how the People’s Free University of Saskatchewan (PFU) is a working model of free, open, community-based education that embodies several characteristics of Whitehead’s philosophy of education. Formed in opposition to the growing commercialization at the original “people’s university,” (the University of Saskatchewan) the PFU has spawned distinctive ideals of its own. The PFU reflects Whitehead’s belief in the importance of shared knowledge fostered by community-based education, the value of abstract and practical knowledge, and the power of the imagination to establish a community of learners capable of acting freely together.  相似文献   

Scientific Collaboration with Educators: Practical Insights from an in‐Class Noise‐Reduction Intervention     

Jessica Massonni  Philippe Frasseto  Denis Mareschal  Natasha Z. Kirkham 《Mind, Brain, and Education》2020,14(3):303-316

Moving the field of Mind, Brain, and Education forward requires researchers and educators to reframe the boundaries of their own discipline in order to create knowledge that is both scientifically based, and of practical relevance for education. We believe that this could be done by co‐constructing research projects from the start. We present a case study of a noise‐reduction intervention in elementary classrooms, in which teachers and researchers worked together from the onset of study design. We examine the processes behind: (1) selecting research questions and measures, (2) planning interventions, (3) receiving ethical approval and funding, (4) recruiting schools, and (5) collecting data. At each step, our study provides suggestions for future collaborative efforts, keeping in mind broader theoretical and methodological implications. We believe that our concrete examples and suggestions will be useful for beginning and confirmed researchers, as well as teachers aiming to know more about research projects.  相似文献   

Peer evaluation: A case study   总被引：1，自引：0，他引：1  

Richard L. Weaver II  Howard W. Cotrell 《Innovative Higher Education》1986,11(1):25-39

Peer evaluation is the process whereby students critique the performances of other students. A peer evaluation format emphasizes skills, encourages involvement, focuses on learning, establishes a reference, promotes excellence, provides increased feedback, fosters attendance, and teaches responsibility. The process of peer evaluation is explained, the criteria are specified, the training for use is described, and how standards are maintained is explained. Finally, objections are suggested and addressed. Peer evaluation is a unique, controlled, and precise form of classroom evaluation that involves carefully constructed evaluation instruments, structured classroom situations, and exact evaluative assessments. Peer evaluation is a new and different form of evaluation.  相似文献   

The Status of Career and Technical Education Undergraduate and Graduate Programs in the United States     

Edward C. Fletcher Jr.  Howard R. D. Gordon 《Peabody Journal of Education》2017,92(2):236-253

The purpose of this study was to examine undergraduate and graduate student enrollments, course delivery modes, and curricular trends and issues of CTE programs. Based on findings from 139 program/department coordinators, results emphasized that although CTE programs within institutions of higher education have declined in number (Fletcher, Gordon, Asunda, &; Zirkle, 2015 Fletcher, E., &; Djajalaksana, Y. (2015). Instructional strategy preferences in the career and technical education classroom. Journal of Research in Business Education, 57(1), 32–56. [Google Scholar]), student enrollments within those programs have remained steady compared to prior studies (Bruening et al., 2001 Bruening, T., Scanlon, D., Hodes, C., Dhital, P., Shao, X., &; Liu, S. (2001). The status of career and technical education teacher preparation programs. (Report No. V051A990004). Minneapolis, MN: The National Research Center for Career and Technical Education. [Google Scholar]; Lynch, 1990 Lynch, R. (1990). A national database on vocational teacher education (Report No. V051A80004-89). Berkeley, CA: National Center for Research in Vocational Education. [Google Scholar]). Even so, CTE program/department administrators have articulated that declining student enrollment is a major challenge within their programs. Additionally, the development of online courses and the impact of state/national educational reform initiatives were identified as major curricular trends for CTE programs. Recommendations include the need for CTE faculty to embrace online instruction, and for programs to use broader nomenclature of CTE/Workforce Education, instead of names of more traditional subdisciplines within the field to remain more accessible and sustainable in the future. The condition of undergraduate and graduate CTE programs will likely impact the viability and sustainability of CTE teacher preparation programs, recruitment of a talented and diverse CTE teaching force, continuity of the U.S. teaching workforce, and ability of K–12 teachers to maintain high-quality CTE programs.  相似文献   

That’s Not Something We Have to Discuss: Interrupting Silences About Multiracial Students in Teacher Work     

Joy Howard 《The Urban Review》2018,50(4):693-712

The author asserts that the field of teacher education must begin a critical conversation to better prepare and support teachers in attending to the complexities of racialized identities, experiences, and perspectives of multiracial students in K12 schools. The author offers a review of literature relevant to multiracial students, and draws from the emerging theoretical framework of Multicrit (Harris in Int J Qual Stud Educ 29(6):795–813, 2016) to present monoracism, ahistoricism, colorism and intersectionality to analyze excerpts from three respective research studies. Each excerpt demonstrates an imperative to build a critical understanding of multiracial students within teacher work. The author concludes with implications for future research and practice.  相似文献   

Teachers' Interpretations of Effective Whole-class Interactive Teaching in Secondary Mathematics Classrooms     

Sonia Jones  Howard Tanner 《Educational studies》2002,28(3):265-274

Prompted by ongoing concerns over standards of numeracy, eight mathematics teachers from four secondary schools in south Wales formed a teacher inquiry group to research the impact of introducing whole-class interactive teaching strategies into their own practice. Possible teaching approaches and activities were developed and agreed during group meetings. These were trialled by the teachers during their normal mathematics lessons. Lesson observations, interviews with teachers and discussions at the group meetings, however, indicated that the implementation of the approaches varied significantly across teachers. This paper analyses the variation in interpretations and teaching styles, and discusses their impact on the quality of the classroom discourse. The determining features discerned within the classroom dialogue included the extent to which pupils were encouraged to reflect on their mathematical knowledge, and the ways in which teachers were able to scaffold pupils' learning.  相似文献
