Identifying pathways of teachers’ PCK development     

Dirk S. Wongsopawiro  Rosanne C. Zwart  Jan H. van Driel 《Teachers and Teaching》2017,23(2):191-210

This paper describes a method of analysing teacher growth in the context of science education. It focuses on the identification of pathways in the development of secondary school teachers’ pedagogical content knowledge (PCK) by the use of the interconnected model of teachers’ professional growth (IMTPG).The teachers (n = 12) participated in a one-year action research project focused on their individual concerns related to teaching science. The use of the IMTPG revealed that teachers use different pathways of learning to develop different aspects of their PCK. For each PCK component, three distinct pathways could be identified, two of which clearly were associated with professional growth. When examining these two pathways in detail, it was found that (1) teachers learned about new instructional strategies and assessment methods mostly through literature reviews and discussions with peers and (2) teachers who analyzed and reflected on student learning as it happened in their classrooms developed understandings that helped them to select and apply instructional strategies to further promote student learning. Both the analytical method as well as the identification of the different developmental pathways help to better understand teacher development in the context of classroom practices.  相似文献   

Application of a transversal laguerre network in adaptive equalization     

K.M. Wong  Y.G. Jan  F.C. Lee 《Journal of The Franklin Institute》1984,317(2):105-115

Synchronous data transmission systems that transmit information over dispersive channels often employ adaptive equalization techniques in the processing of the received signals. Most equalizers presently used in communication systems are of the tapped delay line (TDL) type. In this paper, we propose a class of adaptive equalizers of which the TDL equalizer is a member. Another interesting member of this class is the Laguerre adaptive equalizer which is to be introduced in this paper. The configuration of the Laguerre equalizer is developed. It is found, as shown by the examples, that the Laguerre equalizer is more accurate, and is less sensitive to timing error than the conventional TDL equalizer.  相似文献   

Reconsidering the social and economic purposes of higher education     

Jan McArthur 《高等教育研究与发展》2011,30(6):737-749

In this article I seek to reconsider the social and economic purposes of higher education. It begins with the premise that there appears to be a general trend towards governments positioning higher education primarily in terms of the economic role that it can fulfil. Such a trend, however, has attracted considerable criticism. In this article I argue that the problem for higher education is not it having an economic role, but the narrowness of the way in which that role is often conceptualised. Drawing on critical theory I explore the interrelation of economic and social factors within higher education and the wider society in which it is situated. This article argues for a redefinition of the purposes of higher education to ensure that both universities and workplaces are sites of human creativity and that the profound and exciting work within institutions of higher education benefits all members of society.  相似文献   

Advancing Diversity in STEM     

Paul L. Hill  Rose A. Shaw  Jan R. Taylor  Brittan L. Hallar 《Innovative Higher Education》2011,36(1):19-27

Although progress has been made, greater efforts are needed to promote faculty diversity at the college and university levels, especially in STEM fields. Thus, it is important to elucidate best practices both for increasing awareness of diversity issues pertaining to higher education and for implementing change. This article focuses on the outcomes of a diversity workshop for college and university faculty hosted by the West Virginia Higher Education Policy Commission, Division of Science and Research. More specifically, it elucidates how participation in the workshop translated into practice at the faculty participants’ home institutions.  相似文献   

Socio-cultural variation in reading comprehension development among fifth graders in Peru     

Silvia Morales Silva  Ludo Verhoeven  Jan van Leeuwe 《Reading and writing》2011,24(8):951-969

In this study, the socio-cultural variation in reading comprehension development was examined in 331 fifth graders from schools in Lima, Peru. Reading comprehension was measured using an adaptation of the PIRLS Reading Literacy test. The fifth graders?? reading comprehension results, measured over the course of fifth grade, were related to the development of word decoding, vocabulary, and motivation for reading. Children??s development in these domains was related to their gender, intellectual maturity, home literacy climate, and socio-economic status. Structural Equation Modelling showed that the development of reading comprehension was influenced by the children??s ability to decode words, their vocabulary, and reading motivation. Furthermore, gender and intellectual maturity as well as children??s home literacy climate and socio-economic status appeared to substantially predict reading comprehension development, directly or indirectly. More than half of the variance in reading comprehension by the end of the fifth grade could be explained based on these predictor variables.  相似文献   

On the effects of motivation on reading performance growth in secondary school   总被引：1，自引：0，他引：1  

Jan Retelsdorf  Olaf KöllerJens Möller 《Learning and Instruction》2011,21(4):550-559

This research aimed at identifying unique effects of reading motivation on reading performance when controlling for cognitive skills, familial, and demographic background. We drew upon a longitudinal sample of N = 1508 secondary school students from 5th to 8th grade. Two types of intrinsic reading motivation (reading enjoyment, reading for interest), one type of extrinsic reading motivation (competition), and reading self-concept were measured by self-report questionnaires. Cognitive skills (reasoning, decoding speed) and reading performance were assessed using standardized tests and background variables were collected using student and parent questionnaires. Applying latent growth curve modeling, positive unique effects of reading enjoyment and reading self-concept and a negative unique effect of competition on the initial level of reading performance were recorded. Moreover, a positive unique effect of reading for interest on reading performance growth was recorded. One may conclude that enhancing students’ interest might be fruitful in terms of nurturing reading performance.  相似文献   

Longitudinal Effects of Teacher and Student Perceptions of Teacher-Student Relationship Qualities on Academic Adjustment     

Hughes JN 《The Elementary school journal》2011,112(1):38-60

The shared and unique effects of teacher and student reports of teacher student relationship quality (TSRQ) in second and third grade on academic self views, behavioral engagement, and achievement the following year were investigated in a sample of 714 academically at-risk students. Teacher and student reports of teacher-student support and conflict showed low correspondence. As a block, teacher and student reports of TSRQ predicted all outcomes, above prior performance on that outcome and background variables. Student reports uniquely predicted school belonging, perceived academic competence, and math achievement. Teacher reports uniquely predicted behavioral engagement and child perceived academic competence. Teacher and student reports of the teacher-student relationship assess largely different constructs that predict different outcomes. Implications of findings for practice and research are discussed.  相似文献   

Bilingual teaching for multilingual students? Innovative dual-medium models in Slovene-German schools in Austria     

Judith Purkarthofer  Jan Mossakowski 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2011,57(5-6):551-565

Traditional bilingual education programmes in regional linguistic minority contexts face major challenges within the recent paradigm of linguistic diversity against a background of increasing migration, mobility and trans-locality. Based on three case studies, the authors of this paper focus on how particular dual-medium models are applied in Slovene-German schools in Carinthia, Austria. They examine not only how these schools provide for a balanced bilingual teaching and learning environment, but also how they deal with their students?? multilingual realities and support their identification with bi- and multilingualism. The authors regard schools as institutional sites where linguistic dispositions are subject to discursive power relations and where language policies and educational goals are negotiated by teachers, parents and students alike. Drawing on speaker-centred and ethnographic approaches in sociolinguistic research, the authors seek to document experiences of all actors involved as well as spatial and discursive practices. Through this the authors show how these dual-medium schools achieve particular profiles in multilingual education which are potentially regarded as innovative examples of best-practice and as being of interest for students and families with heterogeneous linguistic backgrounds.  相似文献   

Neurocognitive predictors of reading outcomes for children with reading disabilities     

Frijters JC  Lovett MW  Steinbach KA  Wolf M  Sevcik RA  Morris RD 《Journal of learning disabilities》2011,44(2):150-166

This study reports on several specific neurocognitive process predictors of reading outcomes for a sample of 278 children with reading disabilities. Three categories of response (i.e., poor, average, and good) were formed via growth curve models of six reading outcomes. Two nested discriminant function analyses were conducted to evaluate the predictive capability of the following models: (a) an intervention and phonological processing model that included intervention group, phonological awareness, and rapid naming and (b) an additive cognitive neuropsychological model that included measures of memory, visual processes, and cognitive or intellectual functioning. Over and above the substantial explanatory power of the base model, the additive model improved classification of poor and good responders. Several of the cognitive and neuropsychological variables predicted degree of reading outcomes, even after controlling for type of intervention, phonological awareness, and rapid naming.  相似文献   

The influence of competences and support on school performance feedback use     

Jan Vanhoof  Jean Pierre Verhaeghe  Martin Valcke  Peter Van Petegem 《Educational studies》2011,37(2):141-154

Information‐rich environments are created to promote data use in schools for the purpose of self‐evaluation and quality assurance. However, providing feedback does not guarantee that schools will actually put it to use. One of the main stumbling blocks relates to the interpretation and diagnosis of the information. This study examines the relationship between data literacy competences, support given in interpreting the information, actual use of the feedback and potential school improvement effect. A randomised field experiment with 188 school principals from primary education was set up and a post‐test was used to investigate the effects of a support initiative. The results revealed that a minority of schools invested significantly in the interpretation and diagnosis of the school performance feedback (SPF), despite the fact that most of the respondents showed an interest in the SPF report. In addition, data competence support and the subsequent use of feedback were found to be limited.  相似文献
