Issues to Consider in Designing WebQuests: A Literature Review     

Serhat Kurt 《学校用计算机》2013,30(3):300-314

A WebQuest is an inquiry-based online learning technique. This technique has been widely adopted in K–16 education. Therefore, it is important that conditions of effective WebQuest design are defined. Through this article the author presents techniques for improving WebQuest design based on current research. More specifically, the author analyzes the WebQuest technique in terms of the principles of cognitive load theory, interactivity, accessibility, and usability and visual appearance. The author argues that several factors must be taken into consideration in order to effectively design WebQuests that will educate without impeding the learning process.  相似文献   

Lifelong Education‐‐a New Challenge     

Kurt Gestrelius 《International Journal of Science Education》2013,35(3):277-292

Summaries

English

Researchers from Japan, Romania and Sweden, together with the UNESCO Institute for Education (Hamburg), carried out a study of the functions of lifelong learning within education. Dozent Gestrelius reconstructs and comments on the Swedish part of this study. He delineates a comprehensive list of criteria which may be of paramount importance for curriculum renewal in science education. The author describes, in addition, the relations between some parts of Swedish curricula and the principles of lifelong learning (for example, self‐realization, self‐directed learning, creativity, flexibility). These are the results of empirical studies.  相似文献   

Improving educational web search for question-like queries through subject classification     

Tolga Yilmaz  Rifat Ozcan  Ismail Sengor Altingovde  Özgür Ulusoy 《Information processing & management》2019,56(1):228-246

Students use general web search engines as their primary source of research while trying to find answers to school-related questions. Although search engines are highly relevant for the general population, they may return results that are out of educational context. Another rising trend; social community question answering websites are the second choice for students who try to get answers from other peers online. We attempt discovering possible improvements in educational search by leveraging both of these information sources. For this purpose, we first implement a classifier for educational questions. This classifier is built by an ensemble method that employs several regular learning algorithms and retrieval based approaches that utilize external resources. We also build a query expander to facilitate classification. We further improve the classification using search engine results and obtain 83.5% accuracy. Although our work is entirely based on the Turkish language, the features could easily be mapped to other languages as well. In order to find out whether search engine ranking can be improved in the education domain using the classification model, we collect and label a set of query results retrieved from a general web search engine. We propose five ad-hoc methods to improve search ranking based on the idea that the query-document category relation is an indicator of relevance. We evaluate these methods for overall performance, varying query length and based on factoid and non-factoid queries. We show that some of the methods significantly improve the rankings in the education domain.  相似文献   

Using 9-1-1 call data and the space–time permutation scan statistic for emergency event detection     

Hector Jasso  William Hodgkiss  Chaitan Baru  Tony Fountain  Don Reich  Kurt Warner 《Government Information Quarterly》2009

During medium to large-scale emergency events such as fires or earthquakes, emergency response teams must be deployed to the location of the event in a timely fashion. Information gathered from 9-1-1 call makers is useful for this, but is not always accurate. In this paper, we show how the space–time permutation scan statistic can be used to detect the presence and location of such events by monitoring the overall spatiotemporal pattern of 9-1-1 emergency calls instead. In an analysis of collected 9-1-1 call data, top detected clusters were found to correlate with emergency events as reported on the news, showing the algorithm's usefulness for automatically estimating their location and temporal extent. We show how the detection procedure works in cases where the emergency event generates a small but statistically significant increase in the number of 9-1-1 calls, as well as cases where events must be detected against a large background activity of 9-1-1 calls. We discuss the possible adoption of the proposed algorithm within the next generation digital government framework.  相似文献   

Poverty, Relationship Conflict, and the Regulation of Cortisol in Small and Large Group Contexts at Child Care     

Gabrielle Rappolt-Schlichtmann  John B. Willett  Catherine C. Ayoub  Robert Lindsley  Annmarie C. Hulette  Kurt W. Fischer 《Mind, Brain, and Education》2009,3(3):131-142

The purpose of this research is to explore the dynamics of cortisol regulation in the context of center-based child care by examining the impact of social context (large classroom vs. small group) and relationship quality with caregivers (conflict with mothers and teachers). We extend the research on children's physiologic stress system functioning in center-based child care by focusing on morning cortisol levels among young children living in poverty. While in high-quality center-based child care, children's cortisol levels decreased over the course of the morning—a result that contrasts with findings in previous research with middle-class children, for whom cortisol typically increased over the course of the day while attending center-based child care. Cortisol levels were further reduced when children were moved from a large classroom environment to a small group context. Relationship conflict with mothers and teachers moderated these effects. Children who had high conflict with their mother exhibited cortisol levels that remained higher (decreased less) over the course of the morning, and children who had high conflict with their teacher exhibited cortisol levels that remained higher (decreased less) in response to the small group context. These results indicate that high-quality child care has the potential to support reduced stress among children living in poverty, at least as indicated by adrenocortical activity.  相似文献   

A Sport Education Fitness Season’s Impact on Students’ Fitness Levels,Knowledge, and In-Class Physical Activity     

Jeffery Kurt Ward  Danielle D. Wadsworth  Shelby Foote  Sheri J. Brock  Nikki Hollett 《Research quarterly for exercise and sport》2017,88(3):346-351

Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.  相似文献

The changing world of international protection of intellectual property     

Kurt Stanberry 《Publishing Research Quarterly》1991,7(1):61-77

Economic and ideological motives underpin differing positions on the protection of intellectual property, with the strongest divisions running between developed and less developed countries. Protection for intellectual property rests on international treaties and agreements, regional arrangements, bilateral agreements, and unilateral actions. In recent years, nations that have been notorioushavens for piracy have sought to bring their laws and enforcement more into line with international standards.  相似文献
