There is a large number of relationships between organisms in communities, and these relationships comprise the following types: predation and parasitism, commensalism, protocooperation and mutualism, neutralism, amensalism, and competition. The possible effects of the relationship between two species are that one or the other can benefit (+),…

This paper explores the influence of symbolic or representational learning materials on pupil engagement or learning outcomes, when 14-16 year old pupils use common types of science simulations. The project pilot phase involved three (15-16 year old) male pupils and a main phase involved twenty-one (14-15 year old) pupils. A retrospective accounts…

Eisner, Gardner, and others have argued that the arts should be better integrated into the K-12 curriculum. In this study we examine three high school senior boys who, as part of a unit of instruction on identity, each produced a mask through which he artistically expressed his sense of self. Using a sociocultural framework based in the work of…

In this study, we consider the potential of multimedia cases as tools for teacher professional development. Specifically, we examined online and face-to-face discussions that occurred within groups composed of pre-service mathematics teachers, in-service mathematics teachers, mathematicians, and mathematics teacher educators. Discussions within…

The purpose of this grounded theory study was to examine the process by which people with Mild Traumatic Brain Injury (MTBI) access information on the web. Recent estimates include amateur sports and recreation injuries, non-hospital clinics and treatment facilities, private and public emergency department visits and admissions, providing…

The Internet is a significant information resource for students due to the ease of access it allows to a vast amount of information. As the quality of the information on the Internet varies, it is important that students are able to evaluate such information critically. The aim of the study was to investigate how students evaluate Internet sources…

This book examines the "think aloud method," which asks people to think aloud while solving a problem so that the resulting protocol can then be analyzed to answer questions about problem solving behavior. The method is presented in detail in the book, along with examples. The book finds that the method is useful both for psychological…

This paper details a study of knowledge-building activities in the domain of computer software. Thirty-six adults--evenly split among beginning, intermediate, and advanced knowledge levels--were videotaped while they attempted to learn a common spreadsheet package. Subjects were asked to think aloud while learning. Each knowledge building activity…

An exploratory study investigated how writers represent their task to themselves before beginning to write. Using data from verbal protocols, the initial plans of 12 writers (5 experts and 7 student writers) who were working on an expository writing task were examined. The protocols were coded for types of planning. Independent measures of the…

Noting that recent issues of several scholarly journals have contained criticism of protocol analysis and the use of verbal reports in the analysis of the writing process, this paper examines some of the charges made and then explores the implications of the criticisms. Specific charges addressed in the paper include the following: (1) protocols…

An order form used in a university printing office was evaluated, redesigned, and tested to determine whether the original or the revised version could be completed more quickly and accurately. Two types of subjects were used: six "experienced" subjects who had previously used the old version of the form, and six "novice" subjects who had never…

Claims recent research involving premature editing--thinking aloud for the study--is too narrow in scope to allow for basic writers whose writing processes do not resemble the model. Using eight basic writers produces evidence to support the claim that many or most basic writers can write without editing prematurely.(NH)

Looks at the nature of introspective accounts and the usefulness of such accounts in studies of the composing process. Concludes that retrospective journal accounts are a rich source of information because they permit consideration of the complex context in which composing occurs. (FL)

A student's understanding of a problem before he or she solves it is a critical component of successful problem solving. This understanding is based on how a problem is represented; that is, whether a problem is understood in terms of principles or solution methods or whether the focus is on features that are irrelevant to its solution. In this…

Reviews research on thinking aloud in reading comprehension that considers thinking aloud as a method of inquiry, a mode of instruction, and a means for encouraging social interaction. Current efforts in engaging students in constructing meaning from text in collaborative discussions indicate the increased importance of social interaction in…
