Anxiety/Uncertainty Management theory, as formulated by Gudykunst and Hammer (1987a), proposes that intercultural adaptation outcomes are based on the two mediating dimensions of uncertainty reduction and anxiety reduction and sixteen secondary variables that systematically influence uncertainty and anxiety reduction. In this paper, the sixteen variables originally identified are categorized into four “fundamental factors”; (interpersonal saliencies, intergroup saliencies, communication message exchange, and host contact conditions). The present study examines this revised Anxiety/Uncertainty Management (AUM) theory of intercultural adaptation. A total of 291 international students at two universities in the United States participated in the study. The study found overall fit of the revised AUM theory vis‐a‐vis the two mediating factors of uncertainty and anxiety reduction, the importance of interpersonal saliencies for uncertainty reduction, and the importance of host contact conditions for facilitating feelings of comfort and reducing anxiety. Intergroup saliencies were significantly related to uncertainty reduction but not, contrary to expectation, to anxiety reduction. Communication message exchange (which consists of information gathering strategies and second language proficiency) was, again contrary to expectation, not significantly related to either uncertainty or anxiety reduction. Finally, cultural identity showed a small though significant negative relationship to intergroup saliencies, suggesting a stronger, ingroup identity was associated with increased uncertainty. The paper concludes by proffering explanations for the findings and suggestions for future research.  相似文献

The present study seeks to identify factors among university students that may be associated with homophobic attitudes and whether homophobia may be reduced by educational interventions, such as knowledge-based curricula found in college sexuality courses. Participants were 128 undergraduate students attending a small, private university in the northwestern region of the United States. At the beginning and end of the fall semester 2004, survey packets consisting of a demographic questionnaire, the Sexual Opinion Survey, the Homophobia Scale, a sexual knowledge survey, and the Bem Sex Role Inventory were administered to students attending a human sexuality class and a comparison group of students enrolled in professional and social science introductory courses. Relative to the comparison group, homophobia levels significantly decreased over the course of the semester among students attending the sexuality class. The effect of attending the class on reducing homophobia was partially mediated by an increase in self-reported knowledge about sexual matters. Taken together, these results suggest that the knowledge-based curriculum of sexuality courses may play an important role in affecting broader attitudes about sexuality among college students, including attitudes about homosexuality.  相似文献

Abstract

This article describes the use of two linked instruments, the Instructor Effectiveness Check Sheet (IEC) and Instructor Effectiveness Questionnaire (IEQ). The use of an evaluation instrument during a course can enable improvements to be made — even with experienced instructors. Detail can be taken from the IEC and IEQ to find obvious and not so obvious needed changes and attention to individuals in the group. The article gives an example where the instruments were used to teach instructors about different pedagogical constructs, describes further research using the instruments at the Nantahala Outdoor Center, USA, and describes a case study on a wilderness education group that illustrated improvement in effective teaching.  相似文献

ABSTRACT

As an increasing number of Jewish summer camps welcome campers with disabilities, it becomes more important to understand the experience of these campers and that of their neurotypical peers. In this study, campers with disabilities and neurotypical campers participated together in a photography activity. Photographs and their accompanying narratives were analyzed, yielding three categories of results: (1) camp community and responsibility (2) Jewish experience at camp; and (3) challenges and opportunities. Results are discussed in terms of enhancing the experience of inclusion at camp for all campers.  相似文献

Multiple-choice (MC) reading comprehension test items comprise three components: text passage, questions about the text, and MC answers. The construct validity of this format has been repeatedly criticized. In three between-subjects experiments, fourth graders (N 1 = 230, N 2 = 340, N 3 = 194) worked on three versions of MC items from the Progress in International Reading Literacy Study 2001 reading comprehension test with relevant components successively deleted: “original version” (text, questions, MC-answers), “version without text” (questions, MC-answers), “version without text and without questions” (only MC-answers). Answering correctly the MC items became more difficult as the relevant information was eliminated. In the two narrative fictional texts presented, the students' performance of the version without text was not better than chance. Conversely in the informational (fictional) text, the students' performance of the version without text was better than chance. In the third condition, students' performance was never better than chance.  相似文献

For over 30 years, researchers and practitioners have identified challenges unique to small, rural community colleges. The purpose of this study was to examine the distinctive problems facing rural community colleges today and the challenges those institutions must address to fulfill their mission in rural America. There are 5 current challenges commonly identified by 10 rural community college administrators in Kansas: technology use, grant writing, an evolving student population and corresponding changes to the mission, funding inequalities between institutions, and hiring qualified people. Identified challenges were compared with problems described in the literature from the last 30 years.  相似文献

Four methods for estimating a dynamic factor model, the direct autoregressive factor score (DAFS) model, are evaluated and compared. The first method estimates the DAFS model using a Kalman filter algorithm based on its state space model representation. The second one employs the maximum likelihood estimation method based on the construction of a block-Toeplitz covariance matrix in the structural equation modeling framework. The third method is built in the Bayesian framework and implemented using Gibbs sampling. The fourth is the least squares method, which also employs the block-Toeplitz matrix. All 4 methods are implemented in currently available software. The simulation study shows that all 4 methods reach appropriate parameter estimates with comparable precision. Differences among the 4 estimation methods and related software are discussed.  相似文献

ABSTRACT

In a quasiregular orthography like English, children inevitably encounter irregular words during reading. Previous research suggests successful reading of an irregular word depends at least partially on a child’s ability to address the mismatch between decoded form and stored word pronunciation, referred to as a child’s set for variability, and the word’s relative transparency, measured here using a spelling to pronunciation transparency rating. Item-level analyses were used to explore the relationship between general child performance on the set for variability mispronunciation task, word specific set for variability (predicting reading of that word), spelling to pronunciation transparency rating, and irregular word reading. Significant predictors included general word reading, general set for variability performance, and item-specific set for variability performance; word frequency and spelling to pronunciation transparency rating; and an interaction between word reading and the transparency rating. Results underscore the importance of considering both general and item-specific factors affecting irregular word reading.  相似文献

ABSTRACT

Science teachers are being called on to incorporate engineering practices into their classrooms. This study explores whether the Engineering-Infused Lesson Rubric, a new rubric designed to target best practices in engineering education, could be used to evaluate the extent to which engineering is infused into online science lessons. Eighty lessons were selected at random from three online repositories, and coded with the rubric. Overall results documented the strengths of existing lessons, as well as many components that teachers might strengthen. In addition, a subset of characteristics was found to distinguish lessons with the highest level of engineering infusion. Findings are discussed in relation to the potential of the rubric to help teachers use research evidence-informed practice generally, and in relation to the new content demands of the U.S. Next Generation Science Standards, in particular.  相似文献

Rigoberta Menchú has become an icon for the struggles of oppressed peoples for justice and self-determination. For many academics and activists around the world, the accusations of lying made against Ms. Menchú by David Stoll brought into sharp focus the politics of "truthmaking" and the absolutist categories of fact and fiction. In this attempt to discredit Ms. Menchú, and through her, the Mayan experience of genocide by the Guatemalan military and its U.S. sponsors, important questions have been raised about how and when Third World women can speak, the conditions under which they will be heard, and the strategies used to silence them. In this paper, the author draws upon some of the lessons of the Rigoberta Menchú case to examine the politics of truth making in Canada in a recent controversy regarding a speech she made criticizing American foreign policy and urging the women's movement to mobilize against America's War on Terrorism. The highly personalized nature of the attacks on the author by political and media elites sought to accomplish a closing down of public space for informed debate about the realities of U.S. foreign policy and to silence dissent. Repeatedly emphasizing her status as an immigrant outsider, this controversy also contributed to the (ongoing) racialization of people of color as a treacherous "enemy" within the nation's geographical borders, against whom "Canadians" had to be mobilized.  相似文献
