A Didactic Sequence of Elementary Geometric Optics Informed by History and Philosophy of Science     

Paulo Maurício  Bianor Valente  Isabel Chagas 《International Journal of Science and Mathematics Education》2017,15(3):527-543

The concepts and instruments required for the teaching and learning of geometric optics are introduced in the didactic process without a proper didactic transposition. This claim is secured by the ample evidence of both wide- and deep-rooted alternative concepts on the topic. Didactic transposition is a theory that comes from a reflection on the teaching and learning process in mathematics but has been used in other disciplinary fields. It will be used in this work in order to clear up the main obstacles in the teaching-learning process of geometric optics. We proceed to argue that since Newton’s approach to optics, in his Book I of Opticks, is independent of the corpuscular or undulatory nature of light, it is the most suitable for a constructivist learning environment. However, Newton’s theory must be subject to a proper didactic transposition to help overcome the referred alternative concepts. Then is described our didactic transposition in order to create knowledge to be taught using a dialogical process between students’ previous knowledge, history of optics and the desired outcomes on geometrical optics in an elementary pre-service teacher training course. Finally, we use the scheme-facet structure of knowledge both to analyse and discuss our results as well as to illuminate shortcomings that must be addressed in our next stage of the inquiry.  相似文献

CICBS: a methodology and a framework for measuring and managing intellectual capital of cities. A practical application in the city of Mataró     

José María?ViedmaEmail author 《知识管理研究与实践》2004,2(1):13-23

The governments of cities have to make important decisions on the future of their communities. In the past, the vision, objectives, and goals of cities have been determined mainly by considering tangible assets as the main factors of a city's prosperity. However, in the knowledge economy, the role of intangible assets in wealth creation has become fundamental. As a result, a framework of intangible assets that allows navigation from the present reality to the future vision has become an urgent need for all cities. The paper has two well-defined parts. In the first part, it develops a specific methodology and framework for measuring and managing the intellectual capital of cities. In the second part, the study deals with the practical application of this model of intellectual capital in cities with the specific case of the city of Mataró, providing some details of the first cities’ intellectual capital report.  相似文献

Influence of intellectual capital upon knowledge creation in Spanish subsidiaries: an empirical study     

Patrocinio Zaragoza-Sáez  Enrique Claver-Cortés  Bartolomé Marco-Lajara  Mercedes Úbeda-García 《知识管理研究与实践》2016,14(4):489-501

Knowledge creation is one of the most important dynamic capabilities that firms can use to develop new assets, which can represent the basis for future innovations. Within a context of growing globalisation, the acquisition and creation of knowledge is one of the main objectives sought with international expansion. The consideration of intellectual capital within the knowledge creation process in subsidiaries offers an innovative way to undertake knowledge management practices in multinationals. Theoretical and empirical works can be found in the literature about intellectual capital. However, very few studies link intellectual capital to knowledge creation in multinationals. Seeking to fill this gap, the purpose of this paper is to develop and test a model that includes the main intangibles belonging to structural and relational capital that can influence knowledge creation in Spanish subsidiaries of foreign multinational firms belonging to high-technology and knowledge-intensive sectors. Theoretical, empirical and managerial contributions result from this paper.  相似文献   

Asynchronous and synchronous online teaching: Perspectives of Canadian high school distance education teachers     

Elizabeth Murphy  María A. Rodríguez‐Manzanares  Michael Barbour 《British journal of educational technology : journal of the Council for Educational Technology》2011,42(4):583-591

This paper presents the results of an inductive, interpretive analysis of the perspectives of 42 Canadian high school distance education (DE) teachers on asynchronous and synchronous online teaching. The paper includes a conceptual overview of the affordances and constraints of each form of teaching. Findings provided insight into the following aspects of asynchronous and synchronous online teaching: degree of use; the tools used; the contexts in which each occur; students' preferences; and limitations. Pedagogy emerged as more important than media for both asynchronous and synchronous online teaching. Synchronous online teaching relied on teacher‐ rather than student‐centred approaches. Asynchronous online teaching provided support for self‐paced, highly independent forms of secondary DE supplemented by synchronous online teaching for answering questions and troubleshooting.  相似文献

The impact of a peer-tutoring program on quality standards in higher education     

José L. Arco-Tirado  Francisco D. Fernández-Martín  Juan-Miguel Fernández-Balboa 《Higher Education》2011,62(6):773-788

The purposes of this study were, on one had, to determine the impact of a peer tutoring program on preventing academic failure and dropouts among first-year students (N = 100), from Civil Engineering, Economics, Pharmacy, and Chemical Engineering careers; while, on the other hand, to identify the potential benefits of such tutoring program on the cognitive and metacognitive learning strategies and social skills of student mentors in their last year of studies or already in a postgraduate program (N = 41) at the University of Granada (Spain). After building and selecting the measurement instruments necessary to gather demographic and academic relevant information on both samples, and assigning first-year students to either an experimental or control group, the intervention consisted of ten 90-min tutoring sessions during the first semester lead by student tutors who, in turn, had undergone four 3-h training sessions on tutoring contents like planning and time management, cognitive and metacognitive learning strategies, motivational strategies and the use of materials designed ad hoc for this program. The results show differences in favour of the treatment group on grade point average, performance rate, success rate and learning strategies and, also, statistically significant pre-post differences for the tutors on learning strategies and social skills.  相似文献   

The moral dimension of class and gender identity-making: poverty and aggression in a secondary school in the city of Buenos Aires     

Analía Inés Meo 《British Journal of Sociology of Education》2011,32(6):843-860

This paper presents some results of a qualitative study carried out in a secondary school in the city of Buenos Aires (Argentina). It examines how two students from poor families responded to, and viewed, aggression by peers at their school. This paper argues that the examination of students’ narratives about aggression (based on classism and sexism) illustrates the analytical usefulness of the moral dimension of social life to unpack crucial aspects of the micro politics of class and gender and processes of identity-making. Following Sayer, this article maps students’ responses to immoral sentiments and misrecognition: the search for respect and respectability, and moral boundary drawing. It demonstrates that these reactions are entangled in students’ class and gender identity-making. It also shows how ‘victims’ are able to regain respect. However, the individualized nature of these processes and the spirals of aggression they instigate demonstrate the fragile and temporary nature of this achievement.  相似文献
