Content analysis of computer conferencing transcripts

Within the field of higher education, there are situations where the learner is not well served in a classroom setting. Problematic issues such as scheduling, critical mass, time, pace and location have the potential to be counterbalanced by e-learning. Within this, the asynchronous nature of today's online learning environments and computer conferencing tools have popularly been claimed to offer tremendous benefits for learners who are willing to take responsibility for their own learning, to progress at their own pace, and interact with their online teacher to get immediate feedback on their learning and progress. Indeed, increasingly, educators today are very keen to exploit some of these new technologies for the benefit of their learners. It is argued in this article that there is a need to address the practice and research of asynchronous computer mediated conferencing. As conferencing tools become an increasingly common feature in students' experience, teachers need to have an understanding of how these tools facilitate the formation and maintenance of collaborative learning communities.

在“经”与“权”之间——学校德育课程内容的社会学分析

当下的德育内容“厚经薄权”使得德育模式不能承受如此之重。,在主体性德育模式中．德育内容“假”框架限制主体;在活动德育模式中,德育内容“大”主题阉割活动：在“学会关心”德育模式中,德育内容“空”结构扼杀关心．。德育内容本身的理论偏差是矛盾的主要方面。它掺杂着太多的理想主义痕迹。“教育就是社会化”的命题能够在较大程度上修正德育内容表述的偏颇之处。在一定意义上,教会学生社会化就是教学生学会选择。未来的德育内容需围绕幸福教育和社会平等教育两个方面来建构。     

Content analysis of inquiry-based tasks in high school biology textbooks in Mainland China

Since inquiry was first introduced to science education, a lot of inquiry-based tasks have appeared in textbooks for supporting an inquiry-based approach. These tasks have great potential to direct the implementation of an inquiry-based approach, as teachers rely heavily on the use of existing instructional materials in most K-12 classrooms. However, these tasks would not actually take effect unless they could accomplish the mission of assisting in the achievement of the educational goals of an inquiry-based approach, for which it is necessary to assess the design quality of inquiry-based tasks in textbooks. Content analysis is an effective way to evaluate the design quality of textbooks. This study adopted the instrument – the Inquiry-based Tasks Analysis Inventory (ITAI), which fits the purpose and has strong reliability and validity – to analyse the inquiry-based tasks in current high school biology textbooks in Mainland China. The results show that (1) some of the inquiry-based tasks separate the inquiry process from scientific content, (2) current textbooks do not present balanced dispositions to use inquiry process skills, and (3) inquiry-based tasks in current textbooks do not reflect a proper understanding about scientific inquiry. The findings call for revisions of inquiry-based tasks in textbooks and indicate the ambiguous understanding about inquiry that may be held by the textbook authors. What is more, the problems revealed by this study are very similar to those found in previous studies in other regions, which highlights the need for continuous attention to the evaluation of inquiry-based tasks in textbooks.     

Content analysis in AV communication research

Conclusion We have briefly attempted to deineate the field of content analysis of communication media and point out of value of content analysis as a method of audio-visual research. On the following pages is a bibliography of that part of the literature on content analysis which seems mostuseful for audio-visual researchers.While the bibliography is fairly comprehensive it does tend to omit studies dealing with the analysis of printed materials. The quantitative analysis of the content of instructional materials has been virtually neglected. Here some useful applications of the technique are made to audio-visual communication research. Donald Auster is an instructor in the Audio-Visual Center at Indiana University.

基于内容分析法的重大突发事件内涵辨析

针对目前重大突发事件概念混乱的现象,本文运用内容分析法对1998-2008年国内外文献中51个有影响力的重大突发事件概念进行了分析,提炼出51个重大突发事件概念中最频繁出现的能代表其内涵的11个标准,分别是：爆发突然/无法预测/可以控制/危害巨大/影响力强/涉及面广/紧迫决策/人员伤亡/环境污染/财产损失/社会公共安全。通过对这些标准的识别,本文对重大突发事件在操作层面上进行了重新架构,将重大突发事件这一术语定义为＂无法预测且突如其来的,影响力强、涉及面广,危害巨大,但可以控制、需要管理部门紧迫决策的恶性事件。＂其中,＂危害巨大＂包括造成重大人员伤亡、巨大财产损失、生态环境的严重破坏以及给社会公共安全带来严重威胁。     

A dynamic analysis of social capital-building of international and UK students

Although many international students experience transitional issues, most research assumes these issues will disappear over time. Using principles of social capital theory, this study addressed whether after three years of study students were able to build multi-national and host social capital links. In this quantitative study of 81 students from 28 nationalities, the results indicate that Confucian Asian students lived in separate social worlds, while English and other international students developed substantial multi-national networks over time. Learning networks after 14?weeks were predicted by group allocation and initial friendships, indicating a positive effect of mixing multi-national groups.     

Measuring Textbook Content Coverage: Efficient Content Analysis with Lesson Sampling

This study addresses measurement issues around a standards-based content analysis of mathematics textbooks’ coverage of standards for use in large-scale monitoring of standards implementation as proposed in a 2013 report by the National Research Council. An earlier study produced an exhaustive content analysis of textbooks using the 2012 Common Core State Standards for Mathematics. This yielded an accurate and reliable portrait of a textbook's coverage of standards. However, such an in-depth analysis is not feasible for large-scale standards-implementation monitoring in which a large number of textbooks may need to be analyzed. To provide such a portrait with sufficient accuracy while also substantially reducing the associated resources needed to produce such a portrait, a simulation study was conducted with the exhaustively coded database to compare different sampling schemes. Results indicated that sampling 1 day from each week and coding the corresponding lessons led to sufficiently accurate representations of the overall content of the textbook. The results provide empirical evidence for large-scale standards-based content analyses of mathematics textbooks for monitoring standards implementation which could be adapted for other subject areas.

The Quality of Content Analyses of State Student Achievement Tests and Content Standards

This article examines the reliability of content analyses of state student achievement tests and state content standards. We use data from two states in three grades in mathematics and English language arts and reading to explore differences by state, content area, grade level, and document type. Using a generalizability framework, we find that reliabilities for four coders are generally greater than .80. For the two problematic reliabilities, they are partly explained by an odd rater out. We conclude that the content analysis procedures, when used with at least five raters, provide reliable information to researchers, policymakers, and practitioners about the content of assessments and standards.

Integrating qualitative and quantitative approaches to the analysis of video data on classroom teaching

Video data provide a means of integrating quantitative and qualitative approaches to the study of classroom teaching. This chapter begins by discussing the usefulness of integrating quantitative and qualitative analyses, and then describes how large-scale video surveys can enable a cyclical process of generating and validating discoveries. The importance of sampling and technology as they bear on efforts to implement the process is noted. The advantages video data offer to researchers are described. Finally, the TIMSS Video Study, a large-scale international video survey of mathematics lessons, is used to illustrate how this cyclical process can be applied to the analysis of lesson content.
