Research-based digital games hold great potential to be effective tools in supporting next-generation science learning. However, as with all instructional materials, teachers significantly influence their implementation and contribute to their effectiveness. To more fully understand the contributions and challenges of teacher implementation of digital games, we studied the replacement of existing high school biology genetics lessons over a 3- to 6-week period with Geniverse, an immersive, game-like learning environment designed to be used in classrooms. The Geniverse materials infuse virtual experimentation in genetics with a narrative of a quest to heal a genetic disease; incorporate the topics of meiosis and protein synthesis with inheritance; and include the science practices of explanation and argumentation. The research design involved a quasi-experiment with 48 high school teachers and about 2000 students, student science content knowledge and argumentation outcome measures, and analysis using hierarchical linear modeling. Results indicate that when Geniverse was implemented as the designers intended, student learning of genetics content was significantly greater than in the comparison, business-as-usual group. However, a wide range of levels of Geniverse implementation resulted in no significant difference between the groups as a whole. Students’ abilities to engage in scientific explanation and argumentation were greater in the Geniverse group, but these differences were not statistically significant. Observation, survey, and interview data indicate a range of barriers to implementation and teacher instructional decisions that may have influenced student outcomes. Implications for the role of the teacher in the implementation of game-based instructional materials are discussed. 相似文献

Higher education confers significant private and social benefits. Māori and Pacific peoples are under-represented within New Zealand universities and have poorer labour market outcomes (e.g., lower wages, under-represented in skilled professions). A New Zealand tertiary education priority is to boost Māori and Pacific success in an effort to improve outcomes for these graduates, their communities and society in general. Using information collected in the Graduate Longitudinal Study New Zealand, we compared Māori and Pacific university graduate outcomes with outcomes of other New Zealand graduates. Data were collected when the participants were in their final year of study (n?=?8719) and two years post-graduation (n?=?6104). Employment outcomes were comparable between Māori, Pacific and other New Zealand graduates at two years post-graduation; however, Māori and Pacific graduates had significantly higher student debt burden and financial strain over time. They were significantly more likely to help others (e.g., family) across a range of situations (e.g., lending money), and reported higher levels of volunteerism compared to their counterparts. Boosting higher education success for Māori and Pacific students has the potential to reduce ethnic inequalities in New Zealand labour market outcomes and may result in significant private benefits for these graduates and social benefits as a result of their contribution to society. 相似文献

画家M.C.埃舍也许能够描绘出这样的画卷,一大群缸鱼进行迁徙,层层叠叠地奔往墨西哥湾的地平线上。有时透过机翼下面3英尺,可以看到这些长着钝钝脑袋的“滑翔机”们以顺时针方向从尤卡坦半岛出发,经过海湾,追逐温暖的海水和阳光,到处捕食,把从沙地里找来的被吞噬的贝放在牙床上磨碎。海洋生态学家朱丽·尼尔声称:“这些家伙一次只产一个小仔儿,一年只产一次。”上千只缸鱼能够聚集在一起确实是件非常壮观的事情。 相似文献

This study examined the utility of intact (i.e., topic outline format) and embedded (i.e., appropriately positioned within the text) headings as processing aids with nonnarrative text. The argument was advanced that headings potentially provide useful cues for both input and output processing but that little empirical evidence exists to either support or refute this proposition. It was further argued that each of the prior studies reviewed were subject to one or more methodological criticisms which may attenuate the generality of the findings. The results of the present study indicated that no advantage accrued to students on the basis of training; however, limitations of this finding are discussed in terms of the amount of training provided and the time available to the students for integrating the new strategies with their existing techniques. The major result of this investigation was that students provided with text containing intact and embedded headings significantly outperformed students whose text did not contain these processing aids. The major benefits were observed at delayed testing; the text-with-headings students recalled approximately 11% more information at immediate testing and 44% more information at delayed testing than the text-without-headings students. Implications of these results and future research issues are discussed. 相似文献

In a seminal article on question negotiation, Taylor outlines four levels of question formulation which pertain to the client-information professional interview session. The literature which supports Taylor's theory is covered. It is proposed that Taylor's four levels may be inadequate for describing question negotiation in the online presearch interview. An altered model is given with suggestions for testing the model in the online environment. Some recommendations concerning the importance of discovering such a model are offered. 相似文献

随着机构仓储(IR,Institutional Repositories)的发展日益成熟,越来越多的图书馆利用协会或是区域关系为机构仓储的发展提供资助、方法、专门技术.对于那些没有专门的机构、时间或者基础的组织来说,采用这种方式建立机构仓储是可行的.犹他州数字仓储计划(http//harvester.lib.utah.edu/utan_ir/)由ISTA提供基金支持,目的是建立一个全州范围的仓储模型.项目主要研究犹他州大学图书馆机构库的发展和增长情况,项目建立在西山数字图书馆(MWDL,Mountain west Digital Library)现有框架基础上.犹他州数字仓储计划提供了一个图书馆员操作的工具箱、培训机制和技术支持,在这个过程中,试验点(pilot sites)发展成为IR.对任何规模的图书馆这个框架模型都可以为他的机构仓储工作的开展提供支持.用户在一个网站上就能对多个数据库的数据进行集成检索.文章除了为读者提供了开发过程中的调查资料和统计资料外,主要目标是为了让图书馆都参与到资源共享的过程中来. 相似文献
