TL;DR: The Inquiry Synthesis Project (ISP) as discussed by the authors was created to synthesize findings from research conducted between 1984 and 2002 to address the research question, What is the impact of inquiry science instruction on K-12 student outcomes? The timeframe of 1984 to 2002 was selected to continue a line of synthesis work last completed in 1983 by Bredderman et al.
Abstract: The goal of the Inquiry Synthesis Project was to synthesize findings from research conducted between 1984 and 2002 to address the research question, What is the impact of inquiry science instruction on K-12 student outcomes? The timeframe of 1984 to 2002 was selected to continue a line of synthesis work last completed in 1983 by Bredderman (Bredderman (1983) Review of Educational Research 53: 499-518) and Shymansky, Kyle, and Alport (Shymansky et al. (1983) Journal of Research in Science Teaching 20: 387-404), and to accommodate a practicable cut- off date given the research project timeline, which ran from 2001 to 2006. The research question for the project was addressed by developing a conceptual framework that clarifies and specifies what is meant by ''inquiry-based science instruction,'' and by using a mixed-methodology approach to analyze both numerical and text data describing the impact of instruction on K-12 student science conceptual learning. Various findings across 138 analyzed studies indicate a clear, positive trend favoring inquiry-based instructional practices, particularly instruction that emphasizes student active thinking and drawing conclusions from data. Teaching strategies that actively engage students in the learning process through scientific investigations are more likely to increase conceptual understanding than are strategies that rely on more passive techniques, which are often necessary in the current standardized-assessment laden educational environment.

TL;DR: The Focus Group Guidebook provides a comprehensive overview of focus group research, covering the reasons for using them, timing, costs, ethical considerations, and case studies.
Abstract: Providing a general introduction to focus group research, Morgan includes the appropriate reasons for using focus groups and what you can expect to accomplish with them. He provides a brief history of focus groups, a discussion of when to use focus groups and why, and several brief case studies illustrating different uses of focus groups. The author covers the timeline and costs associated with focus groups, including a discussion of the ethical issues involved in focus group research. Thoroughly covering all the information to help you start your focus group project, this guidebook is appropriate for anybody beginning a focus group, as well as managers or clients who will be using focus groups.

TL;DR: Previous research on engineering student design processes is extended to compare the design behavior of students and expert engineers to support the argument that problem scoping and information gathering are major differences between advanced engineers and students, and important competencies for engineering students to develop.
Abstract: In this paper we report on an in-depth study of engineering design processes. Specifically, we extend our previous research on engineering student design processes to compare the design behavior of students and expert engineers. Nineteen experts from a variety of engineering disciplines and industries each designed a playground in a lab setting, and gave verbal reports of their thoughts during the design task. Measures of their design processes and solution quality were compared to pre-existing data from 26 freshmen and 24 seniors. The experts spent significantly more time on the task overall and in each stage of engineering design, including significantly more time problem scoping. The experts also gathered significantly more information covering more categories. Results support the argument that problem scoping and information gathering are major differences between advanced engineers and students, and important competencies for engineering students to develop. Timeline representations of the expert designers' processes illustrate characteristic distinctions we found and may help students gain insights into their own design processes.

TL;DR: This article reviewed three visual methods based on drawing that I applied in my research on young people: the arts-based projective technique, the self-portrait, and the graphic elicitation methods of the relational map and the timeline.
Abstract: This article reviews three visual methods based on drawing that I applied in my research on young people: the arts-based projective technique, the self-portrait, and the graphic elicitation methods of the relational map and the timeline. Examples of these methods are drawn from their application in two studies, the Narratives of Identity and Migration project, exploring young people and identities in England and Italy, and the Young Lives and Times. The article argues that applying these drawing methods in the context of an interview can open up participants' interpretations of questions, and allow a creative way of interviewing that is responsive to participants' own meanings and associations. The article discusses the analytical potential of graphic elicitation and arts-based methods, by making reference to the insights that they offered in the contextual analysis with more traditional text-based data. The efficacy of these methods is critically discussed, together with their limitations, and their potential within the context of qualitative longitudinal research.

TL;DR: A detailed characterization of Twitter, an application that allows users to send short messages, is presented, which identifies distinct classes of Twitter users and their behaviors, geographic growth patterns and current size of the network.
Abstract: Web 2.0 has brought about several new applications that have enabled arbitrary subsets of users to communicate with each other on a social basis. Such communication increasingly happens not just on Facebook and MySpace but on several smaller network applications such as Twitter and Dodgeball. We present a detailed characterization of Twitter, an application that allows users to send short messages. We gathered three datasets (covering nearly 100,000 users) including constrained crawls of the Twitter network using two different methodologies, and a sampled collection from the publicly available timeline. We identify distinct classes of Twitter users and their behaviors, geographic growth patterns and current size of the network, and compare crawl results obtained under rate limiting constraints.
