Emergent patterns of teaching/learning in electronic classrooms   总被引：1，自引：0，他引：1

Novel patterns of teaching/learning have emerged from faculty and students who use our three teaching/learning theaters at the University of Maryland, College Park. These fully-equipped electronic classrooms have been used by 74 faculty in 264 semester-long courses since the fall of 1991 with largely enthusiastic reception by both faculty and students. The designers of the teaching/learning theaters sought to provide a technologically rich environment and a support staff so that faculty could concentrate on changing the traditional lecture from its unidirectional information flow to a more collaborative activity. As faculty have evolved their personal styles in using the electronic classrooms, novel patterns of teaching/learning have emerged. In addition to enhanced lectures, we identified three common patterns: (a) active individual learning, (b) small-group collaborative learning, and (c) entire-class collaborative learning.  相似文献   

The Use of the Microgenetic Method with Children with Disabilities: Discovering Competence     

Kathryn L. Fletcher  Lisa F. Huffman  Norman W. Bray  Lisa A. Grupe 《Early education and development》1998,9(4):357-373

In this paper, we advocate the use of the microgenetic method, a methodology that combines dense sampling of observations across time and extensive trial-by-trial analysis, to examine strategy change in children with disabilities. This methodology has revealed new information about normally achieving children's cognition, such as large individual variability in strategy use among children of the same age and more gradual patterns of strategy change than previously assumed. In this paper, we review data from three different microgenetic studies in the domains of memory, arithmetic, and reading with children with or at risk for mental retardation and normally achieving children. Our review indicates that there are similar sequences of strategy change, similar rates of strategy change, and similar frequency of strategy discovery and use in children with and without mental retardation (compared to mental age peers). Implications are discussed for the use of this methodology to design instructional techniques for children with disabilities.  相似文献

Geographical education and ideology in England and Wales     

Norman Graves 《Prospects》1998,28(2):263-270

Conclusion If ideology is a nexus of ideas which represent the values of a society and the way that society operates, then clearly such ideas, in so far as they are held by those who have power in society, are bound to affect what is taught within the system of education. This may not be openly avowed, though in totalitarian regimes the education system is determinedly used to enforce the only ideology—that of those in power. The saving grace in a democratic system is that those being educated have access ideologies other than the dominant one. In England and Wales and to some extent elsewhere in the United Kingdom, there is little doubt that the geography curriculum has tended to serve the dominant ideology during the heyday of the British Empire and even during its period of decline in the 1930s and 1940s. In the 1960s and 1970s, an alternative ideology stressing the rights of the underprivileged became manifest in a geography curriculum that was not controlled centrally. The 1980s saw a reversal of this trend by those who had political power, though the reason advanced for the greater control of the curriculum was couched in terms of the economic needs of the nation and the desire to raise standards. But clearly those in power considered that theraison d'être of education was to promote an enterprise culture. However, in practice no ideology is ever pure. When the enterprise culture came into contact with long-cherished ideas of national sovereignty, marrying the two proved difficult. This was reflected in the neutral (not to say negative) position of the national curriculum in geography with respect to the European Union.

The influence of history of science courses on students' views of nature of science     

Fouad Abd‐El‐Khalick  Norman G. Lederman 《科学教学研究杂志》2000,37(10):1057-1095

This study (a) assessed the influence of three history of science (HOS) courses on college students' and preservice science teachers' conceptions of nature of science (NOS), (b) examined whether participants who entered the investigated courses with a conceptual framework consistent with contemporary NOS views achieved more elaborate NOS understandings, and (c) explored the aspects of the participant HOS courses that rendered them more “effective” in influencing students' views. Participants were 166 undergraduate and graduate students and 15 preservice secondary science teachers. An open‐ended questionnaire in conjunction with individual interviews, was used to assess participants' pre‐ and postinstruction NOS views. Almost all participants held inadequate views of several NOS aspects at the outset of the study. Very few and limited changes in participants' views were evident at the conclusion of the courses. Change was evident in the views of relatively more participants, especially preservice science teachers, who entered the HOS courses with frameworks that were somewhat consistent with current NOS views. Moreover, explicitly addressing certain NOS aspects rendered the HOS courses relatively more effective in enhancing participants' NOS views. The results of this study do not lend empirical support to the intuitively appealing assumption held by many science educators that coursework in HOS will necessarily enhance students' and preservice science teachers' NOS views. However, explicitly addressing specific NOS aspects might enhance the effectiveness of HOS courses in this regard. Moreover, the study suggests that exposing preservice science teachers to explicit NOS instruction in science methods courses prior to their enrollment in HOS courses might increase the likelihood that their NOS views will be changed or enriched as a result of their experiences with HOS. © 2000 John Wiley & Sons, Inc.

Cognitive assessment of function knowledge     

Edward R. Karpp  Norman H. Anderson 《科学教学研究杂志》1997,34(4):359-376

Two theories of assessing function knowledge were compared for intuitive physics. The choice assessment theory, derived from Piaget, presents subjects with two physical situations, each specified by the values of two physical variables; subjects choose the situation which will yield the greater value of a dependent variable. Functional measurement presents subjects with a single physical situation; subjects make a quantitative estimate of the dependent variable. Forty subjects made both choice and functional measurement responses for two situations of intuitive physics. The choice theory showed substantial frequencies of stepwise rules, implying that subjects failed to integrate the two given physical variables. Functional measurement, in contrast, showed that most subjects integrated the two variables, following exact addition or multiplication rules. It is concluded that functional measurement gives a more correct assessment of function knowledge and should be useful in science instruction. J Res Sci Teach 34: 359–376, 1997.  相似文献   

Teachers' understanding of the nature of science and classroom practice: Factors that facilitate or impede the relationship     

Norman G. Lederman 《科学教学研究杂志》1999,36(8):916-929

The purpose of this multiple case study was to investigate the relationship of teachers' understanding of the nature of science and classroom practice and to delineate factors that facilitate or impede a relationship. Five high school biology teachers, ranging in experience from 2 to 15 years, comprised the sample for this investigation. During one full academic year, multiple data sources were collected and included classroom observations, open‐ended questionnaires, semistructured and structured interviews, and instructional plans and materials. In addition, students in each of the teachers' classrooms were interviewed with respect to their understanding of the nature of science. Using analytical induction, multiple data sources were analyzed independently and together to triangulate data while constructing teacher profiles. The results indicated that teachers' conceptions of science do not necessarily influence classroom practice. Of critical importance were teachers' level of experience, intentions, and perceptions of students. The results have importnat implications for teacher education as well as the successful implementation of current reforms. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 916–929, 1999  相似文献   

Fairness and Consequential Validity of Teacher Work Samples     

Peter Denner  Antony Norman  Shu-Yuan Lin 《Educational Assessment, Evaluation and Accountability》2009,21(3):235-254

Acknowledging the necessity to establish the fairness and consequential validity of teacher candidate performance assessments when they are used to make high-stakes decisions impacting entry into the profession, we investigated whether there were any adverse results from the use of the Renaissance Teacher Work Sample (TWS) assessment at two universities as a consequence of the age, gender, or race/ethnicity of teacher candidates. We also investigated education program and program entrance requirements, such as Praxis I scores, and measures of grade point average, as general predictors of TWS success. The findings indicated no disparate impact or adverse consequences based on the gender, age, or race/ethnicity of the teacher candidates. Selected variables did predict a moderate amount of the variance of the TWS total scores of both preinterns and student-teaching interns. The process used to determine the value implications of the results was also discussed.  相似文献   

Class-wide Positive Behavior Support in Preschool: Improving Teacher Implementation Through Consultation     

Deborah Russell Carter  Renee K. Van Norman 《Early Childhood Education Journal》2010,38(4):279-288

As the number of young children displaying challenging behavior in early childhood grows, so too does the need to implement evidence-based practices that prevent challenging behavior. Positive Behavior Support (PBS) provides a framework of tiered interventions focused on promoting social-emotional development and preventing challenging behavior. This study investigated the effects of consultation on teachers’ implementation of universal PBS practices and children’s academic engagement. A multiple-baseline design was applied across four preschool classrooms serving children from 33 to 63 months of age. A strong relationship was documented between consultation and teachers’ implementation of PBS skills. High levels of academic engagement were maintained following consultation. Implications of the results are provided for applications of universal PBS practices in early childhood settings.  相似文献
