To determine what knowledge of genetics is needed for decision-making on genetic-related issues, a consensus-reaching approach was used. An international group of 57 experts, involved in teaching, studying, or developing genetic education and communication or working with genetic applications in medicine, agriculture, or forensics, answered the questions: “What knowledge of genetics is relevant to those individuals not professionally involved in science?” and “Why is this knowledge relevant?” The answers were classified in different knowledge components following the PISA 2015 science framework. During a workshop with the participants, the results were discussed and applied to seven cases in which genetic knowledge is relevant for decision-making. The analysis of these discussions resulted in a revised framework consisting of nine conceptual knowledge components, three sociocultural components, and four epistemic components. The framework can be used in curricular decisions; its open character allows for including new technologies and applications and facilitates comparisons of different cases.  相似文献

Abstract

This issue is the second of a special PRIMUS two-part issue collecting articles on undergraduate research from experienced faculty mentors. We offer it as a valuable resource for faculty leading undergraduate research programs. This issue presents a collection of papers offering advice on a variety of specific topics important for leaders of undergraduate research programs. Issues of finding and designing appropriate and accessible research projects, assessing undergraduate research, and publicizing it in the media are addressed.  相似文献   

Content integration as a factor in math-game effectiveness     

Sylke Vandercruysse  Judith ter Vrugte  Ton de Jong  Pieter Wouters  Herre van Oostendorp  Lieven Verschaffel  Jan Elen 《Educational technology research and development : ETR & D》2017,65(5):1345-1368

In this study we focus on the integration of mathematical learning content (i.e., proportional reasoning) in game-based learning environments (GBLE). More specifically, two kinds of GBLEs are set up: an extrinsically integrated GBLE and an intrinsically integrated GBLE. In the former environment, the mathematical content is not part of the core mechanics and structure of the gaming world. In the latter environment, the mathematical content is delivered through the parts of the game that are the most fun to play and embodied within the structure of the gaming world and the players’ interactions with it. Sixty-four vocational track students participated in the study, all of them working in either version of the self-developed GBLE “Zeldenrust”. The results of this study suggest that the way the content is integrated in a GBLE (i.e., intrinsically or extrinsically) matters: contrary to our expectations, students who played the extrinsically integrated game showed higher learning gains, motivational gains and perceived usefulness than students who played the game in which the content was intrinsically integrated.  相似文献   

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
