Diversity of thought in the blogosphere: implications for influencing and monitoring image
A blog, a shortened form of weblog, is a website where an author shares
thoughts in posts or entries. Most blogs permit readers to add comments to posts and
thereby be a conversational mechanism. One way that companies have started to use
blogs is to monitor their corporate image (in this dissertation, the term image is used in
reference to corporate, brand and/or product image). This study focuses on how common
socio-psychological processes mediate consumersā revelation of corporate image in the
blogosphere. Centering resonance analysis, a means of measuring similarity between
two bodies of text, is used in conjunction with multidimensional scaling to locate text as
cognitive objects in a space. Clusters are then detected and measured to quantify
diversity in the thoughts expressed. Detected patterns are studied from a social process
theory perspective, where complex phenomena are hypothesized to be the result of the
interaction of simpler processes. A majority of blog commenters compromise the expression of their thoughts to
gain social acceptance. This study identifies the most extreme of such people so
companies who monitor blogs can assign less weight to image indications gained from
them as they may be merely expressing thoughts that are intended to maintain social
acceptance.
It was also found that single-theme blogs attract a readership with similarly
narrow interests. The boldest and most diverse thinkers among comment writers have the
most impact because of their ability to provoke the thinking of others. However,
commenters who repeat the same ideas have little effect, suggesting that introducing
shills is unlikely to shift the sentiment of a blogās readership.
People participate in blog communities for reasons (e.g., need for community)
that may undermine thought diversity. However, there may be value in serving those
needs even though no valuable insights are provided into image or directions for product
development. Members of homogeneous-thinking communities were observed to more
actively participate, with greater longevity. This may increase loyalty to the company
hosting the blog
Theoretical and Practical Advances in Computer-based Educational Measurement
This open access book presents a large number of innovations in the world of operational testing. It brings together different but related areas and provides insight in their possibilities, their advantages and drawbacks. The book not only addresses improvements in the quality of educational measurement, innovations in (inter)national large scale assessments, but also several advances in psychometrics and improvements in computerized adaptive testing, and it also offers examples on the impact of new technology in assessment. Due to its nature, the book will appeal to a broad audience within the educational measurement community. It contributes to both theoretical knowledge and also pays attention to practical implementation of innovations in testing technology

Technology and Testing
From early answer sheets filled in with number 2 pencils, to tests administered by mainframe computers, to assessments wholly constructed by computers, it is clear that technology is changing the field of educational and psychological measurement. The numerous and rapid advances have immediate impact on test creators, assessment professionals, and those who implement and analyze assessments. This comprehensive new volume brings together leading experts on the issues posed by technological applications in testing, with chapters on game-based assessment, testing with simulations, video assessment, computerized test development, large-scale test delivery, model choice, validity, and error issues. Including an overview of existing literature and ground-breaking research, each chapter considers the technological, practical, and ethical considerations of this rapidly-changing area. Ideal for researchers and professionals in testing and assessment, Technology and Testing provides a critical and in-depth look at one of the most pressing topics in educational testing today
Differentiating Instruction to Close the Achievement Gap for Special Education Students Using Everyday Math
Thesis advisor: Robert J. StarrattThis case study examined teacher collaboration and teacher change while in the process of differentiating instruction in the area of mathematics in an elementary school. The project included a two-tier professional development opportunity for the staff. Professional development sessions focusing on specific mathematics skills were offered in lieu of traditional faculty meetings and thirteen, teacher volunteers in grades K-3 participated in bi-monthly study groups. The study describes the journey of the thirteen teachers as they identified successful strategies for differentiating instruction to meet the needs of all learners. The study explored how job-embedded professional development offered teachers the resources and support to meet together during the school day to engage in dialogue about their students' progress, difficulties encountered when teaching specific concepts and skills, and proactively planning in order to differentiate instruction effectively. The study focused on collaboration as a method for learning together in an adult learning environment and improving current teacher practices. The research was qualitative with the school principal as both researcher and participant-observer of the study. Data instruments used for the participants involved in this study were pre- and post-implementation surveys of the entire staff, semi-structured interviews of the thirteen teacher volunteers, observations of meetings, teachers' reflective journals, and field notes. Findings indicated that there was an increase in the teachers' use of differentiated instruction in the area of math. While teachers most often differentiated lessons by ability, teachers experimented with differentiating by interest as well as addressing the students' varying learning styles. In addition, teachers found that the embedded study groups were valuable in helping them to collaborate with their peers and improve their practice in teaching mathematics to all learners. In a profession where continual renewal is necessary, it is essential for educators to be provided with adequate time to review current practices, reflect on the strategies that are most successful, and refine their craft in order to provide opportunities that will maximize student thinking and learning.Thesis (EdD) ā Boston College, 2009.Submitted to: Boston College.

Enhancing Free-text Interactions in a Communication Skills Learning Environment
Learning environments frequently use gamification to enhance user interactions.Virtual characters with whom players engage in simulated conversations often employ prescripted dialogues; however, free user inputs enable deeper immersion and higher-order cognition. In our learning environment, experts developed a scripted scenario as a sequence of potential actions, and we explore possibilities for enhancing interactions by enabling users to type free inputs that are matched to the pre-scripted statements using Natural Language Processing techniques. In this paper, we introduce a clustering mechanism that provides recommendations for fine-tuning the pre-scripted answers in order to better match user inputs
