高中历史教科书“中国近现代社会生活的变迁”专题编撰存在的问题及建议

在对"中国近现代社会生活的变迁"专题的编撰中,人教版和人民版都局限于史实的列举和阶段标志性事件的陈述,忽视对与此相应的前因后果等内在联系的阐明。岳麓版某些章节编写较好,但重要知识点缺失度较高。此外,完全符合课标内容的"乳房解放运动"和"新中国成立后计划经济时代居室建筑"等内容,应当写进教科书。     

省属高校图书馆学科馆员角色定位探讨

"学科馆员"是图书馆学界的一个全新的研究领域,在高校学科建设中起着重要作用。高校图书馆学科馆员的角色定位直接关系到学科服务工作的开展与成败。省属高校无论在硬件、软件方面都与重点高校存在距离,所以重点高校对学科馆员的定位并不适合省属高校。省属高校图书馆学科馆员的角色定位应为"联络、导航、教育"。

Secondary Students’ Stable and Unstable Optics Conceptions Using Contextualized Questions

This study focuses on elucidating and explaining reasons for the stability of and interrelationships between students’ conceptions about Light Propagation and Visibility of Objects using contextualized questions across 3 years of secondary schooling from Years 7 to 9. In a large-scale quantitative study involving 1,233 Korean students and 1,149 Singaporean students, data were analyzed from responses to the Light Propagation Diagnostic Instrument consisting of four pairs of items, each of which evaluated the same concept in two different problem situations. Findings show that only about 10–45 % of students could apply their conceptions of basic optics in contextualized problem situations giving rise to both stable and unstable alternative conceptions. Students’ understanding of Light Propagation concepts compared with Visibility of Objects concepts was more stable in different problem situations. The concepts of Light Propagation and Visibility of Objects were only moderately correlated. School grade was not a strong predictive variable, but students’ school achievement correlated strongly with their conceptual understanding in optics. The teaching and learning approach and education systems in the two countries may have had some influence on students’ conceptual understanding.     

Academic social bookmarking: An empirical analysis of Connotea users

Three groups of social bookmarking users, namely experienced users, users with moderate level of experience, and novice users, were investigated, in terms of their reported tagging behaviors, perceived usefulness of social bookmarking in information discovery and management, and perceived usefulness of the bookmarking features provided. Based on the empirical analysis of the Connotea users, who are primarily in academia, the study shows that experienced academic users generally prefer to use social bookmarking while moderately experienced and novice users still prefer to use the traditional bookmarking methods, such as creating and using bookmarks on a dedicated computer. Experienced academic users were also found to create more tags per bookmark comparing to the other two groups. Most novice academic users, however, only created one tag per bookmark, which just met Connotea's minimum requirement. Surprisingly different from the collaborative design nature of the social bookmarking systems, the study finds that our participants, particularly experienced academic users, prefer to create and use their own bookmarks rather than sharing bookmarks created by others. In fact, experienced users have significantly higher frequency (once every two weeks) of creating bookmarks than the other two groups (once a month or less). In addition, website design features and functions, such as automatic collection of bibliographic information, are regarded by all participants as helpful for information discovery. The in-depth examination and discussion of the opinions of Connotea users may be useful for further improvement of the design features and usage applications, particularly for academic social bookmarking websites. The results may also have potential implications to the future development of social bookmarking services in general.
