Didactic material confronted with the concept of mathematical literacy     

Uwe Gellert 《Educational Studies in Mathematics》2004,55(1-3):163-179

This paper reflects on the use of didactic material in mathematics classes. It focuses on the mathematical activities of students and the didactical activities of teachers. Its point of departure is a critique of technical-managerial approaches to teaching, learning, and innovation. Based on this critique, fundamental tensions between the development of new didactic material and the cognitive style and daily routines of practising teachers are identified. In the last part of the paper, the concept of mathematical literacy is introduced in order to set the crucial relationship between didactic material for mathematics instruction and the ways in which it is used in the classroom on new and fertile grounds.  相似文献   

International research networks in pharmaceuticals: Structure and dynamics     

Uwe Cantner  Bastian Rake 《Research Policy》2014

Knowledge production and scientific research have become increasingly more collaborative and international, particularly in pharmaceuticals. We analyze this tendency in general and tie formation in international research networks on the country level in particular. Based on a unique dataset of scientific publications related to pharmaceutical research and applying social network analysis, we find that both the number of countries and their connectivity increase in almost all disease group specific networks. The cores of the networks consist of high income OECD countries and remain rather stable over time. Using network regression techniques to analyze the network dynamics our results indicate that accumulative advantages based on connectedness and multi-connectivity are positively related to changes in the countries’ collaboration intensity whereas various indicators on similarity between countries do not allow for unambiguous conclusions.  相似文献   

"Protoplasm...is soft wax in our hands": Paul Kammerer and the art of biological transformation     

Gliboff S 《Endeavour》2005,29(4):162-167

Paul Kammerer's career ended in scandal in 1926 over tampering with his evidence for "Lamarckian" evolution--the infamous midwife toad. But although Kammerer's conclusions proved false, his evidence was probably genuine. In any case his arguments were not simply for Lamarckism and against Darwinism, as the theories are understood today. If we look beyond the scandal, the Kammerer story shows us a great deal about early 20th-century biology: the range of new ideas about heredity and variation, competing theories of biological and cultural evolution and their applications in eugenics, new kinds of laboratories and professional roles for biologists, and changing standards for documenting experimental results.  相似文献   

The Shanghai Institute for Advanced Studies--A New Type of Science Academy     

Uwe Opolka 《中国科学院院刊(英文版)》2004,18(2)

The Shanghai Institute for Advanced Studies is committed to the outlined goals of the older science academies, but is also trying to look beyond them to find its own course.  相似文献   

Motivational factors in discussing sexual health with young people with chronic conditions or disabilities     

Heleen A. Van der Stege  Sander R. Hilberink  Adriaan P. Visser  AnneLoes Van Staa 《Sex education》2014,14(6):635-651

The objective of this study was to identify determinants of professionals’ intention to use the new board game SeCZ TaLK to facilitate sexual health discussions with young people with chronic health conditions and disabilities, and to gauge whether intention led to actual use. A cross-sectional web-based survey of 336 professionals before they received the game sought to measure their intention to use SeCZ TaLK, their attitudes towards discussing sexuality, social professional environment, self-efficacy, opinion on the feasibility of using the game and experience discussing sexuality. Actual use of SeCZ TaLK was assessed at follow-up (N = 105). Professionals with higher self-efficacy and more experience in discussing sexual health were more likely to intend to use the game. At follow-up, intention to use explained 21% of the variance in actual use. SeCZ TaLK fits easily into the daily practice of professionals working in assisted-living and day-care facilities; other professionals experienced greater difficulty integrating the game into their practice. Despite this, SeCZ TaLk was also used across a wide range of settings including in psycho-educational groups, group consultations in hospitals and group therapy in rehabilitation centres. Professionals appreciated the board game SeCZ TaLK, but actual use depended on their own motivation and skills and compatibility with work routines.  相似文献   

Teaching Environment for the Education of Engineering Students     

Reiner Anderl  Uwe R. Vogel 《Interactive Learning Environments》2013,21(2-3):195-208

The engineering students of today must be educated and trained in the foundations and methods that are necessary for the efficient use of modern technologies and tools, in teamwork and in the procurement and management of information. These goals can only be achieved in a sophisticated course environment that enables the individual work of each student as well as teamwork with data sharing, release procedures, communication, and coordination and which gives access to exercises and exams. All exercises and exams as well as their approval or rejection are done within this environment. The information that is needed for the task is either supplied in the form of lecture material or standards, or it must be found somewhere else on the Web. Within this environment, methods for the application of modern technology and tools are taught and practiced in a “simulated” product development process. This article describes this environment in the mechanical engineering facult y at the Darmstadt University of Technology (http://www.iim.maschinenbau.tu-darmstadt.de).  相似文献   

Estimating the Effect on Grades of Using Multiple-Choice Versus Constructive-Response Questions: Data From the Classroom     

Stephen Hickson  W. Robert Reed  Nicholas Sander 《Educational Assessment》2013,18(4):200-213

This study investigates the degree to which grades based solely on constructed-response (CR) questions differ from grades based solely on multiple-choice (MC) questions. If CR questions are to justify their higher costs, they should produce different grade outcomes than MC questions. We use a data set composed of thousands of observations on individual students in introductory economics classes at a large public university. We note that the instructors of these classes made conscientious efforts to write CR questions that assessed higher levels of learning (Bloom, 1956 Bloom, B. S. 1956. Taxonomy of educational objectives: The classification of educational goals, handbook 1: Cognitive domain. New York: McKay..  [Google Scholar]). Despite this, we find relatively little difference in grade outcomes. Our analysis suggests that switching from an all-CR assessment to an all-MC assessment would produce grade variations that are similar to the differences that are observed for students across different tests. Although other studies have focused on test scores, frequently AP test scores, our study is the first to focus attention on university grades. We hope that our inability to identify substantial benefits to CR questions in terms of grades will stimulate further research to identify substantive benefits from using the more costly CR questions.  相似文献   

Young children’s overestimation of performance: A cross-cultural comparison     

Mengtian Xia  Astrid M. G. Poorthuis  Qiang Zhou  Sander Thomaes 《Child development》2022,93(2):e207-e221

Western literature suggests that young children overestimate their performance across a range of tasks. Research in non-Western cultures, however, is lacking. In 2019, 101 Chinese (52% girls) and 98 Dutch (49% girls) children, ages 4 and 5, were asked to estimate how well they would perform on both a motor and a memory task. Children from both countries overestimated their performance to the same extent ( = .077 and .027 for the motor and memory tasks, respectively). They generally persevered in doing so despite receiving realistic performance feedback. Yet, children overestimated their peers’ performance about as much as their own performance, in some cases even more. This is the first demonstration of performance overestimation in children growing up in a non-Western culture.  相似文献
