Using Differential Item Functioning Procedures to Explore Sources of Item Difficulty and Group Performance Characteristics 总被引:1,自引:0,他引:1
Statistics used to detect differential item functioning can also reflect differential strengths and weaknesses in the performance characteristics of population subgroups. In turn, item features associated with the differential performance patterns are likely to reflect some facet of the item task and hence its difficulty, that might previously have been overlooked. In this study, several item features were identified and coded for a large number of reading comprehension items from the two admissions testing programs. Item features included subject matter content, various properties of item structure, cognitive demand indicators, and semantic content (propositional analysis). Differential item functioning was evaluated for males and females and for White and Black examinees. Results showed a number of significant relationships between item features and indicators of differential item functioning—many of which were consistent across testing programs. Implications of the results for related areas of research are discussed. 相似文献

College students completed a questionnaire that assessed their attitudes toward the level of male responsibility in abortion decisions. Overall, both men and women thought that men should have some degree of involvement in the abortion decision. However, as expected by the first hypothesis, men indicated a desire for more responsibility in the abortion decision than women thought the men should have. A second hypothesis predicted women would feel more strongly than men that abortion was strictly a woman's issue. Contrary to the hypothesis, women tended to disagree that abortion was strictly a women's issue. Implications of the findings are discussed. 相似文献

ABSTRACTBackground and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding. 相似文献

We examined visual recognition memory and executive functioning (spatial working memory [SWM], spatial planning, rule learning, and attention shifting) in 12‐year‐olds (n = 150) who participated in the Bucharest Early Intervention Project, a randomized controlled trial of foster care for institutionally reared children. Similar to prior reports at 8 years of age, institutionally reared children showed significant deficits in visual recognition memory and SWM. Deficits in attention shifting and rule learning were also apparent at this time point. These data suggest that early experiences continue to shape the development of memory, learning, and executive functioning processes in preadolescence, which may explain broader cognitive and learning difficulties commonly associated with severe early life neglect. 相似文献

The authors completed an exploratory factor analysis of the scores of 248 counselors‐in‐training on the Counselor Skills Personal Development Rating Form (CSPD‐RF; M. B. Wilbur, 1991). Participants' counseling program was accredited by the Council for Accreditation of Counseling and Related Educational Programs at a midsize western university. The authors of the CSPD‐RF hypothesized that the CSPD‐RF measured 2 factors: (a) personal development and (b) skills development. Factor analysis yielded 4 factors (Emotional Sensitivity, Basic Listening Skills, Multicultural Skills, and Influencing Skills), accounting for 58.4% of the total variance, thus providing some support for the construct validity of the CSPD‐RF. 相似文献

An interview and an intervention study are reported. Interview findings extend research on the positive relationship of parent involvement to school success. That is, although most of the low income families reported low-moderate participation, a postive relationship was found between parent involvement and school adjustment as early as kindergarten. With respect to negative valuing and barrier interpretations of low participation, the data support the latter; all but a few parents reported positive attitudes toward school involvement, while the majority indicated significant barriers. In comparing Latino and non-Latino groups, the former reported more barriers. Within the Latino group, parents whose children had made a good school adjustment indicated the most participation. Non-English proficient parents reported more barriers than those proficient in English but comparable degrees of involvement. In the intervention study, a simple strategy resulted in more treatment than control parents attending a school event. Differences in attendance were related to ethnicity and language.This work was carried out in conjunction with a dropout prevention demonstration project conducted as a collaborative effort of the School Mental Health unit (Janelle Munn, Director) and Dropout Prevention unit (Pete Martinez, Director) of the Los Angeles Unified School District and the School Mental Health Project at UCLA (Howard Adelman and Linda Taylor, Co-directors). Partial support for the project came from the U.S. Department of Education. The authors, of course, assume full responsibility for the contents, but we want to take this opportunity to acknowledge the contributions of participating schools and project staff (especially Mary Beth DiCecco and Alison McAlpine). And although she declined author credit, this work could not have been accomplished with the many contributions of Linda Taylor, the project director. We would also like to thank Regina DeWitter, Teresa Gonzales, Kathy Eides and the many other UCLA students who assisted in various phases of the research. 相似文献

Current research explores adaptability by gathering teachers' reflections on their adaptations. However, the field knows little of what the term adaptability means to teachers who currently teach in today's educational context. In this article, adaptability is discussed from the perspectives of 3 practicing classroom educators, teaching in various contexts (geographic region and grade level). Teachers' voices of adaptability are examined and a definition of adaptability is discussed. Obstacles are presented in these teachers' efforts to adapt their instruction in their respective contexts. Teachers then discussed the ways in which they navigated these obstacles to modify their instruction to fit a variety of learners and experiences despite these constraints. 相似文献
