Although effects of violence in video games have been researched extensively, no empirical studies have examined effects of profanity, a form of verbal aggression, in video games. An experiment (N = 321) investigated effects of profanity used by protagonist and antagonist characters in a “first-person shooter” game on players' hostile expectations, accessibility of aggressive thoughts, aggressive feelings, and other responses. Profanity used by both protagonist and antagonist characters increased hostile expectations, a direct precursor to aggressive behaviors. Findings suggest that profanity in video games may affect aggressive outcomes, emphasizing the need for more research investigating effects of profanity in media.  相似文献

Using a critical race theory lens, the authors propose a way of writing race research using composite counterstories. Drawing on data from a yearlong study of school rebuilding in the time period immediately after Hurricane Katrina devastated the City of New Orleans, the authors examine the experiences of African-American educators in the school rebuilding efforts. Cook and Dixson look specifically at how composite counterstories speak back to racialized constructions of black educators that justified their post-Katrina displacement and usher in an era of school reform in which New Orleans is described as “ground zero” for the expansion of charter schools, the disempowerment of teachers’ unions, and the re-organization of teacher preparation. Given the context of the research, the authors argue that researchers should consider how composite counterstories facilitate racial research and ensure the protection of research participants.  相似文献

A perennial challenge for urban education in the United States is finding effective ways to address the academic achievement gap between African American and White students. There is widespread and justified concern about the persistence of this achievement gap. In fact, historical evidence suggests that this achievement gap has existed at various times for groups other than African Americans. What conditions prevailed when this achievement gap existed for these other groups? Conversely, under what conditions did the gap diminish and eventually disappear for these groups? This article explores how sociocultural factors involved in the manifestation and eventual disappearance of the gap for these groups may shed some light on how to address the achievement gap for African American students in urban science classrooms. Our conclusion is that the sociocultural position of groups is crucial to understanding and interpreting the scholastic performance of students from various backgrounds. We argue for a research framework and the exploration of research questions incorporating insights from Ogbu's cultural, ecological theory, as well as goal theory, and identity theory. We present these as theories that essentially focus on student responses to societal disparities. Our ultimate goal is to define the problem more clearly and contribute to the development of research‐based classroom practices that will be effective in reducing and eventually eliminating the achievement gap. We identify the many gaps in society and the schools that need to be addressed in order to find effective solutions to the problem of the achievement gap. Finally, we propose that by understanding the genesis of the gap and developing strategies to harness the students' responses to societal disparities, learning can be maximized and the achievement gap can be significantly reduced, if not eliminated entirely, in urban science classrooms. © 2001 John Wiley & Sons, Inc.

The purpose of this study is to determine knowledge of traumatic brain injury among educators. Few studies have examined knowledge of traumatic brain injury in this population and fewer still have included a substantial proportion of general education teachers. Examining knowledge of traumatic brain injury in educators is important as the vast majority of children with traumatic brain injury will return to school and many are likely to require support in the short term and some will require special education services in the long term. The Common Misconceptions of Traumatic Brain Injury questionnaire was completed by 94 educators. Participants demonstrated accurate knowledge on a number of questionnaire items associated with the identification of individuals with traumatic brain injury, common socio-emotional effects, and recovery from traumatic brain injury; however, a considerable degree of uncertainly was indicated on several items relevant to the school setting. In addition, substantial misconception rates were noted on only four items including one pertaining to recovery and another concerning the likelihood of additional brain injuries. Knowing someone with traumatic brain injury, participating in training and having taught a student with traumatic brain injury resulted in greater knowledge. Implications of these findings for educators are discussed.  相似文献

Piaget's structural theory of formal thought suggests that a general construct of formal reasoning exists. The content of the task and type of problem employed are often ignored in Piagetian based studies but are important for generalizing findings to other studies and to educational problems. The study reported here examines content and problem effects of formal thought in 13-year-old adolescents. Specifically, three controlling variables tasks with different content and two question type tests (analysis and controlling questions) were administered to 120 seventh graders. Ability measures and personality dimensions associated with formal reasoning in the literature are used to clarify what formal reasoning is and how content and problem type are involved in formal reasoning. Significant main effects were found for problem and content effects (p = 0.001), and a significant interaction was found between the two (p = 0.001). Across the three tasks general ability, field dependency, and locus of control were consistently and significantly related to the controlling questions. However, only measures of field dependency were related to the analysis questions. Combinations of ability and personality factors were found to be uniquely related to each task, within each question type. Results have implications for a theory of formal thought and the teaching of the controlling variables strategy.  相似文献

Individual person fit analyses provide important information regarding the validity of test score inferences for an individual test taker. In this study, we use data from an undergraduate statistics test (N = 1135) to illustrate a two-step method that researchers and practitioners can use to examine individual person fit. First, person fit is examined numerically with several indices based on the Rasch model (i.e., Infit, Outfit, and Between-Subset statistics). Second, person misfit is presented graphically with person response functions, and these person response functions are interpreted using a heuristic. Individual person fit analysis holds promise for improving score interpretation in that it may detect potential threats to validity of score inferences for some test takers. Individual person fit analysis may also highlight particular subsets of items (on which a test taker performs unexpectedly) that can be used to further contextualize her or his test performance.  相似文献

From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central to a domain can maximize students’ effort associated with constructing new schemas. In addition, interfaces that minimize working memory demands due to the interface per se, for example by mimicking existing non-digital work practice, can preserve students’ attentional focus on their learning task. In this research, we asked the question: What type of interface input capabilities provide best support for science problem solving in both low- and high-performing students? High school students’ ability to solve a diverse range of biology problems was compared over longitudinal sessions while they used: (1) hardcopy paper and pencil (2) a digital paper and pen interface (3) pen tablet interface, and (4) graphical tablet interface. Post-test evaluations revealed that time to solve problems, meta-cognitive control, solution correctness, and memory all were significantly enhanced when using the digital pen and paper interface, compared with tablet interfaces. The tangible pen and paper interface also was the only alternative that significantly facilitated skill acquisition in low-performing students. Paradoxically, all students nonetheless believed that the tablet interfaces provided best support for their performance, revealing a lack of self-awareness about how to use computational tools to best advantage. Implications are discussed for how pen interfaces can be optimized for future educational purposes, and for establishing technology fluency curricula to improve students’ awareness of the impact of digital tools on their performance.  相似文献
