Differential item functioning (DIF) analyses are a routine part of the development of large-scale assessments. Less common are studies to understand the potential sources of DIF. The goals of this study were (a) to identify gender DIF in a large-scale science assessment and (b) to look for trends in the DIF and non-DIF items due to content, cognitive demands, item type, item text, and visual-spatial or reference factors. To facilitate the analyses, DIF studies were conducted at 3 grade levels and for 2 randomly equivalent forms of the science assessment at each grade level (administered in different years). The DIF procedure itself was a variant of the "standardization procedure" of Dorans and Kulick (1986) and was applied to very large sets of data (6 sets of data, each involving 60,000 students). It has the advantages of being easy to understand and to explain to practitioners. Several findings emerged from the study that would be useful to pass on to test development committees. For example, when there was DIF in science items, MC items tended to favor male examinees and OR items tended to favor female examinees. Compiling DIF information across multiple grades and years increases the likelihood that important trends in the data will be identified and that item writing practices will be informed by more than anecdotal reports about DIF. 相似文献

This article examines the possibility of an engagement between the discourse of Development and postcolonial theory. To open up a space for this kind of engagement, the article proposes first that, while there is no singularity of project within the field of Postcolonial Studies, there is a productive set of debates; and second that the necessity of questioning Development as an idea springs out of these debates around the nature and existence of Postcoloniality itself. It attempts to show how the critiques which have currency within postcolonial theory can be used to deconstruct Development and expose the mechanisms and tropes of power which Development as a discourse has in common with colonial discourse and modernity as a project. The scope of this article is to lay the groundwork for a continued engagement of Postcolonial with Political Studies, and in particular with the discourse of Development. 相似文献

Research-based digital games hold great potential to be effective tools in supporting next-generation science learning. However, as with all instructional materials, teachers significantly influence their implementation and contribute to their effectiveness. To more fully understand the contributions and challenges of teacher implementation of digital games, we studied the replacement of existing high school biology genetics lessons over a 3- to 6-week period with Geniverse, an immersive, game-like learning environment designed to be used in classrooms. The Geniverse materials infuse virtual experimentation in genetics with a narrative of a quest to heal a genetic disease; incorporate the topics of meiosis and protein synthesis with inheritance; and include the science practices of explanation and argumentation. The research design involved a quasi-experiment with 48 high school teachers and about 2000 students, student science content knowledge and argumentation outcome measures, and analysis using hierarchical linear modeling. Results indicate that when Geniverse was implemented as the designers intended, student learning of genetics content was significantly greater than in the comparison, business-as-usual group. However, a wide range of levels of Geniverse implementation resulted in no significant difference between the groups as a whole. Students’ abilities to engage in scientific explanation and argumentation were greater in the Geniverse group, but these differences were not statistically significant. Observation, survey, and interview data indicate a range of barriers to implementation and teacher instructional decisions that may have influenced student outcomes. Implications for the role of the teacher in the implementation of game-based instructional materials are discussed. 相似文献

Both the psychological and criminological fields have long hypothesized the mechanisms that influence desistance from violent offending, but few studies have focused on violent females. This study identifies patterns of violent behavior across 7 years among 172 females and 172 matched males ages 15–24, testing if heterogeneity in violent offending is linked to (a) developmental change in impulse control and (b) attainment of adult milestones. Fewer females persist in violence (25%) than males (46%); 19% of males increase in violent behavior. Females who develop impulse control and are employed are more likely to desist from violence. Violent offending is unrelated to other adult milestones. Developmental increases in impulse control may trigger desistance, while employment may maintain desistance from violence. 相似文献

Purpose
Empirical research regarding potential risks and benefits of children's participation in the legal system generally, and in the child dependency legal system in particular, is sparse and mostly characterized by small studies without comparison groups. The current study was designed to address the following questions regarding children's participation in dependency court hearings: (1) Is attending court harmful to children? (2) Is attending court beneficial to children? (3) Is judicial behavior with the child in the courtroom related to potential harms or benefits? and (4) Are there age differences in children's reactions?Method
The authors measured children's reactions to attending dependency review hearings (n = 43) and compared them to a sample of children who did not attend their hearings (n = 50). One to 2 weeks following review hearings, both groups of children were interviewed about their reactions to the court process.Results
Children who attended their hearings reported more positive feelings about the dependency process (e.g., trust in judge, perceived fairness, and more comfort with their guardians ad litem and caseworkers). For children who attended, there was no evidence of high distress immediately preceding or following their hearings. Court observations revealed that more active engagement by judges was related to positive responses from the children. Most children, including both children who attended hearings and those who did not, believed that all children should be able to attend their hearings.Conclusion
Overall, the findings suggest that policies encouraging children's attendance at dependency hearings are viewed positively by and not harmful to children. 相似文献57.

The library collaborating with nonacademic departments to further strategic goals is beneficial for both parties. In the summer of 2016, the Hubert Library at Florida International University began working with the Career Services Department to provide career research assistance to students, alumni, and employees. This paper highlights the elements of this collaboration, discusses the obstacles encountered and how they were dealt with, and provides practical tips for creating better partnerships. 相似文献

This case study explores the affordances a weblog (blog) offered to “Ms. Frizzle,” an urban middle school science teacher and exceptional blogger, to support her professional identity development. The 316 posts she wrote over 1 school year were systematically analyzed and triangulated with data from e-mail exchanges and interviews with Ms. Frizzle and her colleagues. Ms. Frizzle used her blog to tell stories of herself and her classroom, reflect on her practice, work through dilemmas, solicit feedback, and display competence, among other things. By doing so, she was able to wrestle with many issues that are central to the practice of urban science teaching and be recognized by herself and others as a “reform-minded” teacher committed to excellence and equity in education. To realize these benefits, however, Ms. Frizzle invested significant time and energy into her blogging and made certain uses of blogging features. Thus, although this study empirically supports the potential of blogging for teachers' professional identity development, it also indicates that the way in which teachers use blogging will determine the extent of the benefits they can derive from this practice. 相似文献

In this study the authors examined longitudinal achievement goal patterns and their effects on students’ motivation and performance from the 5th to 6th grade in physical education running programs. In their 5th and 6th grade, 412 participants completed questionnaires assessing their task and ego orientations, expectancy beliefs, task values, and intentions for future participation in running. They also completed a timed 1-mile run. Results revealed low task/low ego, low task/high ego, high task/low ego, and high task/high ego remained stable as goal patterns across the 5th and 6th grade. The majority of students moved to more motivationally adaptive goal patterns over time. 相似文献
