Search engine optimization, or the practice of designing a web site so that it rises to the top of the results page when users search for particular keywords or phrases, has become so prevalent on the modern web that it has a significant influence on Google search results. This article examines the techniques used by search engine optimization practitioners, the difference between “white hat” and “black hat” optimization tactics, and why it is important for library staff to understand these techniques and their impact on search engine results pages. It also looks at ways that library staff can help their users develop awareness of the factors that influence search results and how to better assess the quality and relevance of results listings.  相似文献

To design an effective computer science curriculum, educators require a systematic method of classifying the difficulty level of learning activities and assessment tasks. This is important for curriculum design and implementation and for communication between educators. Different educators must be able to use the method consistently, so that classified activities and assessments are comparable across the subjects of a degree, and, ideally, comparable across institutions. One widespread approach to supporting this is to write learning objects in terms of Bloom’s Taxonomy. This, or other such classifications, is likely to be more effective if educators can use them consistently, in the way experts would use them. To this end, we present the design and evaluation of our online interactive web-based tutorial system, which can be configured and used to offer training in different classification schemes. We report on results from three evaluations. First, 17 computer science educators complete a tutorial on using Bloom’s Taxonomy to classify programming examination questions. Second, 20 computer science educators complete a Neo-Piagetian tutorial. Third evaluation was a comparison of inter-rater reliability scores of computer science educators classifying programming questions using Bloom’s Taxonomy, before and after taking our tutorial. Based on the results from these evaluations, we discuss the effectiveness of our tutorial system design for teaching computer science educators how to systematically and consistently classify programming examination questions. We also discuss the suitability of Bloom’s Taxonomy and Neo-Piagetian theory for achieving this goal. The Bloom’s and Neo-Piagetian tutorials are made available as a community resource. The contributions of this paper are the following: the tutorial system for learning classification schemes for the purpose of coding the difficulty of computing learning materials; its evaluation; new insights into the consistency that computing educators can achieve using Bloom; and first insights into the use of Neo-Piagetian theory by a group of classifiers.  相似文献

Media Effectiveness in a Malaysian Park System   总被引:1,自引:0,他引:1  
Abstract

The effectiveness of three media formats (guides, booklets, and signs) were compared for use on a nature trail at Kinabalu Park, Malaysia. Based on a multiple-choice, cognitive test taken by 1,194 visitors, the guide treatment scores were significantly higher than the other media treatments. There was no difference between booklet and sign treatments, and all the media treatments scored higher than the control group (F 3,1190 = 173.76, α = .05). A second experiment compared only booklet and sign media. There was still no difference in effectiveness (Paired t test, t = 0.22, df = 566, p □ .05). The first language and educational backgrounds of visitors influenced media effectiveness. However, age, sex, residence, interest level, prior knowledge, and prior park visitation did not influence the relatively great effectiveness of the guide treatment. Other factors, such as cost, time, and numbers served, may justify use of media formats other than guides.  相似文献

Participation in “communities of practice” is often depicted as a central feature of various theoretical understandings of the social nature of learning. How are such communities of practice to be enacted in distance education, which, by definition, implies spatial detachment? This article reflects on the dimensions of communities of practice experienced by four students undertaking doctoral studies by distance education, working in different countries than the one in which the institution of their studies is based, and at four different phases of their doctoral program. In each writer’s experience, community of practice involvement was identified as critical in program completion, yet the source of the learning community was in each case outside of institutional provision.  相似文献

This article describes the development and implementation in the schools over a 20-year period of the Energy Source Program, a comprehensive K-12 energy education curriculum. The program was developed beginning in 1980 using state-of-the-art development procedures for that time and has been used to date by more than 12 million American students to learn about energy and energy issues. End-of-unit posttest scores for the elementary and high school units averaged above 80% for their field tests. Data obtained from a large sample during the first three years of installation of the program in the schools indicated that posttest scores remained at a level during installation similar to that during the field-test phase. A study conducted in the early 1990s by an independent research organization to assess the program's long-term effects revealed that grade 6 students who had used one or more units from the program had significantly greater energy knowledge and better energy conservation habits than students who had not used any units. A set of 10 guidelines are offered for long-term instructional development and implementation projects. He supervised the development of the Energy Source Program from 1980 to 1984 while serving as a consultant to EDS. Kay Ice was Director of Program Development at EDS, and she was a primary writer and developer of the Energy Source Program. She has been president of EDS since 1999. Fred Niedermeyer was the founding president of EDS. He was project director of the Energy Source project, and he played a major role in all aspects of the project from its inception until his retirement in 1999.  相似文献

The article reviews different views of creativity, building on the work of Czikszentmihaly. It offers a definition of creativity in terms of trait/process/product. The issue of how creativity might be assessed is explored using this definition and some illustrative examples are provided. The article concludes that creativity can and should be assessed but that this must be with an appropriate methodology. Such assessment is important not only for assessing students' work but also for evaluating curriculum content, in order to promote curriculum development in the teaching of creativity.  相似文献
