This paper presents the results of a survey conducted among departmental resource centres in higher education. The survey aimed at quantifying, validating and supplementing information gathered through visits, case studies and the literature and was constructed around six areas: information about each center; details of the learning resources housed in them; an assessment of their use; feedback and evaluation activities; information about the staff in charge of centres; and finally a section on general comments made by respondents. 相似文献

An Onto-Semiotic Analysis of Combinatorial Problems and the Solving Processes by University Students
Juan?D.?GodinoEmail author Carmen?Batanero Rafael?Roa 《Educational Studies in Mathematics》2005,60(1):3-36
In this paper we describe an ontological and semiotic model for mathematical knowledge, using elementary combinatorics as
an example. We then apply this model to analyze the solving process of some combinatorial problems by students with high mathematical
training, and show its utility in providing a semiotic explanation for the difficulty of combinatorial reasoning. We finally
analyze the implications of the theoretical model and type of analysis presented for mathematics education research and practice. 相似文献

Academic language is critical for English learners (ELs) to succeed in the science classroom. This study analyzed the instructional practices centered around academic language taking place in eight, fifth-grade classrooms during a grant-funded project. Observational data collected through a classroom observation instrument were analyzed to describe and compare the instructional practices occurring in treatment and control classrooms when teachers and students used academic language. Our findings show both treatment and control classrooms using academic language during the course of the intervention study, but the instruction looked markedly different in each setting. These differences provide valuable insight for practitioners and researchers concerned with the academic language development of ELs in science classrooms. 相似文献

AbstractThis article describes two collaborative research projects whose common goal was to explore the potential role of professional controversies in building teachers’ summative assessment capacity. In the first project, upper primary teachers were encouraged to compare their practices through a form of social moderation, without prior instructor input or theoretical preparation. In the second project, lower secondary school teachers were encouraged to compare their summative assessment practices with reference to a theoretical model of curriculum alignment, under the guidance of an instructor. The findings support the potentially constructive role of professional controversies in supporting teachers’ professional development for summative assessment. They highlight the status of references called upon in discussion of controversies, and their contribution to the construction of the subjects under discussion. 相似文献

To be fully prepared for the professional workplace, Engineering students need to be able to effectively communicate. However, there has been a growing concern in the field about students’ preparedness for this aspect of their future work. It is argued that online writing tools, to engage numbers of students in the writing process, can support feedback on and development of writing in engineering on a larger scale. Through interviews and questionnaires, this study explores engineering academics’ perceptions of writing to better understand how online writing tools may be integrated into their teaching. Results suggest that writing is viewed positively in the discipline, but it is not believed to be essential to success in engineering. Online writing tools were believed to support a larger number of students, but low knowledge of the tools limited academics’ understanding of their usefulness in teaching and learning. Implications for innovation in undergraduate teaching are discussed. 相似文献

This paper deals with intercultural aspects of privacy, particularly with regard to differences between Japanese and Western
conceptions. It starts with a reconstruction of the genealogy of Western subjectivity and human dignity as the basic assumptions
underlying Western views on privacy. An analysis of the Western concept of informational privacy is presented. The Japanese
topic of ‘‘denial of self” (Musi) as well as the concepts of Seken, Shakai and Ikai (as analyzed by the authors of the companion piece on privacy in Japan) give rise to intercultural comparisons. The paper
addresses the question of privacy in cyberspace and mass media. Finally the question of freedom of speech is related to the
Japanese concepts of Ohyake and Watakusi. 相似文献

This paper discusses the problem of discriminating between individual contributions in the assessment of group projects. It is argued that peer assessment is a necessary element of any proposed structure but that the use of any ‘weighting‐factor’ system is contrary to the philosophy underpinning collaborative groupwork. A structure that separates the process and product elements of the assessment is described and a set of generic criteria for the process peer assessment identified. This structure was implemented with a group of students at Hong Kong University and evaluated using questionnaires and in‐depth interviews. The paper discusses the results of this evaluation and in particular identifies the need for ‘benchmarking’ when using the criteria and also the problematic nature of the ‘insider‐outsider’ syndrome as an important cultural factor. 相似文献

Ontologies are frequently used in information retrieval being their main applications the expansion of queries, semantic indexing of documents and the organization of search results. Ontologies provide lexical items, allow conceptual normalization and provide different types of relations. However, the optimization of an ontology to perform information retrieval tasks is still unclear. In this paper, we use an ontology query model to analyze the usefulness of ontologies in effectively performing document searches. Moreover, we propose an algorithm to refine ontologies for information retrieval tasks with preliminary positive results. 相似文献

Andean Indians have used coca leaves (Erythroxylon coca and related species) for centuries to enhance physical performance. The benefits and disadvantages of using coca leaf have
been a subject of many political debates. The aim of this study was to investigate the effects of chewing coca leaves on biochemical
and physiological parameters. Cutaneous microdialysis catheters were used to estimate systemic biochemical changes. We subjected
10 healthy adult males (local residents) in Cajamarca (Peru, altitude 2700 m) to a standardised exercise routine on a stationary
cycle ergometer. The blood pressure, oxygen saturation (digital), pulse, VO2 max and ECG (Holter monitor) were recorded before
the exercise. Cutaneous microdialysis catheters were introduced in the forearm. The subjects were given to chew 8 g of coca
leaves with a small amount of lime. They were then placed on the cycle ergometer for 20 min. Blood pressure, oxygen saturation,
pulse, ECG and VO2 max were recorded. Pyruvate, glucose, lactate, glycerol and glutamate levels were estimated. Oxygen saturation,
blood pressure, and pulse rate did not show any significant changes between the two groups. Glucose levels showed hyperglycaemic
response. Glycerol, Lactate and Pyruvate increased. Glutamate remained unchanged. Similar changes were not seen in the controls.
These results suggest that coca leaves have blocked the glycolytic pathway of glucose oxidation resulting in accumulation
of glucose and pyruvate. The energy requirement for exercise is being met with beta-oxidation of fatty acids. The glycerol
released was also getting accumulated since its pathway for oxidation was blocked. These experimental findings suggest that
chewing coca leaves is beneficial during exercise and that the effects are felt over a prolonged period of sustained physical
activity. 相似文献
