Differential Item Functioning (DIF) is traditionally used to identify different item performance patterns between intact groups, most commonly involving race or sex comparisons. This study advocates expanding the utility of DIF as a step in construct validation. Rather than grouping examinees based on cultural differences, the reference and focal groups are chosen from two extremes along a distinct cognitive dimension that is hypothesized to supplement the dominant latent trait being measured. Specifically, this study investigates DIF between proficient and non-proficient fourth- and seventh-grade writers on open-ended mathematics test items that require students to communicate about mathematics. It is suggested that the occurrence of DIF in this situation actually enhances, rather than detracts from, the construct validity of the test because, according to the National Council of Teachers of Mathematics (NCTM), mathematical communication is an important component of mathematical ability, the dominant construct being assessed. However, the presence of DIF influences the validity of inferences that can be made from test scores and suggests that two scores should be reported, one for general mathematical ability and one for mathematical communication. The fact that currently only one test score is reported, a simple composite of scores on multiple-choice and open-ended items, may lead to incorrect decisions being made about examinees. 相似文献

ABSTRACTInternational fieldschools to developing countries have become an important component of the university curriculum because they provide experiential learning and research skills, while also contributing a range of soft skills such as resilience, empathy, resourcefulness, critical thinking, and cross-cultural communication. Yet, with the increasing popularity of ‘developing world’ fieldschools, an ever-more pertinent question to ask is, cui bono? Who benefits when relatively ‘privileged’ students from wealthy countries travel to visit ‘underprivileged’ communities in poorer parts of the world? In this article, we contribute to the discussion about fieldschool reciprocity using data from a newly established program in Northern Uganda, established as part of the University of New South Wales’ UNSW2025 strategy. We show that a whole-of-university approach has significant benefits for staff and students from both institutions, more diffuse benefits for the wider Ugandan host community, as well as the potential to create synergies to leverage community transformation. We also look at challenges that include: power differentials, uncertainty in the field environment, sustainability, and the ability to maintain collaborative equity between institutions over the long term. 相似文献

Rapid Feedback Assessment Methods: Can We Improve Engagement and Preparation for Exams in Large-enrollment Courses? 总被引:1,自引:0,他引:1

Scratch-off immediate feedback assessment technique (IF-AT) forms and classroom response systems (clickers) can increase student
engagement and interaction and help students prepare for exams by indicating the type and level of questions they will encounter.
We used the IF-AT throughout the semester in three sections of a lower-division biology class; in two, students worked on
IF-AT questions in small permanent groups, and in one, students alternated between IF-AT and clickers each week. At the end
of the semester, students answered surveys about instant feedback techniques. Students appreciated prompt feedback on their
understanding of course material, enjoyed the group interaction and opportunities to learn from each other, and continued
to have positive perceptions of instant feedback activities and to take them seriously throughout the semester. While appreciating
the versatility of clicker questions, we find that the ease of use, low cost, effectiveness, and improved classroom climate
of the IF-AT method are particularly commendable. 相似文献

Abstract In May 1988 UNESCO set up a Regional Seminar ‐‐ ‘New Technologies for Handicapped in Special Education’ ‐‐at the Wenner‐Gren Centre at Sveavagen in Stockholm, Sweden. This short paper reflects initial draft statements on the conference and is included here to identify the extent of common apprehensions and expectations. It covers the areas of information services, studies and research activities, international co‐operation through staff exchanges and conference activities, and looks briefly at future trends. 相似文献

To implement restorative care in assisted living facilities, staff need to understand the philosophy and learn methods to help residents maintain optimal function. In this study, the researchers developed a multimedia training program designed to teach staff how to encourage residents to increase their participation in dressing themselves. Researchers conducted a pilot test to measure the short-term effects of the training on 40 staff from two states. Program effects were measured by completing a survey developed by the researchers. Pretest scores were significantly related to gender (women as a group had higher scores than men). Results indicated significant gains in knowledge at posttest. In addition, 93% of participants described positive changes related to restorative care that they planned to make at their facility as a result of the training. 相似文献

This study compared staff and elderly knowledge, attitudes, and practices related to sexual expression by elderly persons in a long‐term care setting. Volunteers (N = 194) responded agree or disagree to 159 items. Significant differences were observed between the staff and elderly responses on 36 items. Areas of greatest differences involved knowledge and attitudes about consensual sex and sexual abuse, issues related to family attitudes toward remarriage and sexual expression, and age‐related changes and health problems related to sexuality. Items related to masturbation received the greatest percentage of no response. The staff had significantly higher total scores as compared to the elderly reflecting more knowledge, positive attitudes, and support for more proactive responses toward elderly sexuality. Findings have major implications for staff training in long‐term care settings. 相似文献

As a methodological approach, participatory action research (PAR), and its variant of critical action research in education, aims to further social justice and generate transformative change. Although this understanding of PAR is well rehearsed, there is still a gap in detailed explorations of the transformative impact of PAR projects in higher education settings beyond the classroom: how do we then know whether transformative change through PAR has taken place, in which ways, through which processes, and for whom. This article aims to address these questions through proposing the use of a participatory action research cube (PARC) as a human capabilities evaluative framework for personal and structural transformative change enabled by PAR projects. Evaluating transformative change from this perspective rests on both the normative nature of the capabilities approach in its justice concerns, as well as consideration for individual well-being, understood as the expansion of freedoms people have to live the lives they value. Evaluating change both includes personal well-being as well as broader social or structural impact in the direction of more social justice. To demonstrate this empirically, we report on an eight-month PAR project on one rural South African university campus, where 13 undergraduate students were involved in researching gender inequalities on their campus. The PARC analysis highlights the development of capabilities and agency through axes of participation, knowledge development, and public deliberation, as well as identifying the developmental impact of these axes on transformative change for the participants, as well as the university. 相似文献
