The Impact of Multidirectional Item Parameter Drift on IRT Scaling Coefficients and Proficiency Estimates     

Kyung T. Han  Craig S. Wells  Stephen G. Sireci 《教育实用测度》2013,26(2):97-117

Item parameter drift (IPD) occurs when item parameter values change from their original value over time. IPD may pose a serious threat to the fairness and validity of test score interpretations, especially when the goal of the assessment is to measure growth or improvement. In this study, we examined the effect of multidirectional IPD (i.e., some items become harder while other items become easier) on the linking procedure and rescaled proficiency estimates. The impact of different combinations of linking items with various multidirectional IPD on the test equating procedure was investigated for three scaling methods (mean-mean, mean-sigma, and TCC method) via a series of simulation studies. It was observed that multidirectional IPD had a substantive effect on examinees' scores and achievement level classifications under some of the studied conditions. Choice of linking method had a direct effect on the results, as did the pattern of IPD.  相似文献   

Traveling with MI education in a turbulent sea: stories of South Korea     

Myung‐Hee Kim  Kyung‐Hee Cha 《International journal of qualitative studies in education》2013,26(4):389-405

The purpose of this paper is to explore ways in which multiple intelligences (MI) theory has been disseminated in search of its meaning, effectiveness and possibilities over the last decade in Korea. There have been a great number of Korean practitioners who have properly applied an ideal of MI theory in their local context. Western readers will be informed of how actively these educators participate in the grass‐roots reform process. A traditional or teacher‐based image of Oriental education culture may have to be redefined, at least in the current Korean educational context. In doing so, the authors reviewed related literature and research articles written by Korean scholars and practitioners as well as conducting in‐depth and focus‐group interviews nationwide to represent voices of Korean MI educators at school level. There has been substantive evidence that most students guided by MI instruction demonstrated better achievement in several subject areas; students typically labeled low achievers in traditional classrooms became better self‐regulated learners, showing higher self‐esteem. Finally, the Korean research community experienced the emergence of a new collaborative research culture in which MI educators are fully acknowledged as curriculum designers and researchers able to gain insight into culturally appropriate classroom practices. The authors end this paper reflecting on a future hope that the Korean research community will continue, both critically and collaboratively, to examine MI theory to make it more applicable in establishing culturally relevant pedagogical insights.  相似文献   

Making Learning Active with Interactive Whiteboards,Podcasts, and Digital Storytelling in ELL Classrooms     

Jung Won Hur  Suhyun Suh 《学校用计算机》2013,30(4):320-338

The purpose of this study was to examine effective ways to integrate an interactive whiteboard, podcast, and digital storytelling for language proficiency development in English language learners. Researchers integrated these three technologies into a 60-hour intensive summer English program and investigated their impacts on student vocabulary skill development. Researchers collected multiple data including daily video podcasts, vocabulary tests, a student survey, Photostory videos, and a teacher interview. The results showed that using an interactive whiteboard for (a) visual presentations, (b) interactive games, and (c) test reviews was useful for the English language learners to learn new vocabulary and engage in learning. The effects of a digital storytelling project and the video podcasts are also discussed.  相似文献

“Happy Seoul for foreigners”: scenes from multicultural life in South Korea     

Jin Suh Jirn 《Inter-Asia Cultural Studies》2013,14(2):315-322

Abstract

Since the mid-2000s, multiculturalism has become a prominent buzzword in South Korea as the nation, which was founded on the myth of a single bloodline, tries to come to terms with its growing foreign population. This article looks at the figure of the industrial migrant worker who, despite being ignored by the mainstream media, has appeared in a handful of independently produced Korean films, including three—Bandhobi (2009 Bandhobi [???]. 2009. Directed by Shin Dong-il. Seoul: IndieStory Inc. [Google Scholar]), Hello, Stranger (2007 Hello Stranger [?? ?? ???]. 2007. Directed by Kim Dong-hyun. Seoul: IndieStory Inc. Host and Guest [???]. 2005. Directed by Shin Dong-il. Seoul: LJ Film. [Google Scholar]), Where Is Ronny? (2008 Where Is Ronny? [??? ???]. 2008. Directed by Sim Sang-kook. Seoul: JinJin Pictures. [Google Scholar])—that will be discussed here in detail. These films, as I will show, not only provide an alternative perspective on immigrant life in Seoul and other parts of the country, which is more often than not represented through the privileged world of the Western “expat,” but also reveal the underlying tensions and contradictions in Korea's approach to multiculturalism as it tries to regulate diversity through the fiat of legislative policy while ignoring the moral and political choices confronting its citizens as they decide whether or not to befriend the other.  相似文献   

The life satisfaction among older East Asian immigrants: sexual attitudes and knowledge     

Jee Hoon Park  Chang Liu  Mo Yee Lee 《Educational gerontology》2020,46(10):602-614

ABSTRACT

Sexuality in later life is an essential factor for quality of life among older adults However, little is known about the sexuality of older adult immigrants from East Asia who have experienced both Western and Eastern cultures. In addition, we have limited information about the mechanism of how sexual attitudes impact life satisfaction through knowledge of sexuality. To address these knowledge gaps, a cross-sectional research design was conducted by collecting data from older East Asian immigrants aged 60 or over in a large city in a Midwestern state. We analyzed 96 responses using exploratory factor analysis and mediation analysis. The results showed that older adult immigrants who had more open sexual attitudes were likely to possess accurate sexual knowledge. Older adult immigrants’ sexual knowledge mediated the relationship between their sexual attitudes and life satisfaction. The findings highlight the importance of lifelong sexual education for older adult immigrants and recommend social workers train in culturally sensitive approaches.  相似文献   

Rethinking the History of Education for Asian-American Children in California in the Second Half of the Nineteenth Century     

Kyung Eun Jahng 《Educational Philosophy and Theory》2013,45(3):301-317

This article brings to light discourses that constituted the education of Asian-American children in California in the second half of the nineteenth century. Guided by Foucaultian ideas and critical race theory, I analyze California public school laws, speeches of a governor-elect and a superintendent, and a report of the board of supervisors, from the 1860s to the 1880s. During this targeted period, the images and narratives of Asian-American children were inscribed with racism. Racializing politics rendered them to be disqualified from attending public schools. Segregated schooling for them was legally ordered and therefore unquestioned. It was a discursive practice implemented on their bodies by dint of a mechanism of a spatial division. This article reveals the shifting dominancy of discourses regarding Asian-American children. Rather than accepting the given historical facts, I intend to reread historical texts in order to rethink the education of Asian-American children through a Foucaultian encounter with critical race theory. Acknowledging different interpretations of the past events is a way of rethinking them and interrogating the history through the revelation of different histories in the education for Asian-American children.  相似文献   

Effect Size Measures for Differential Item Functioning in a Multidimensional IRT Model     

Youngsuk Suh 《Journal of Educational Measurement》2016,53(4):403-430

This study adapted an effect size measure used for studying differential item functioning (DIF) in unidimensional tests and extended the measure to multidimensional tests. Two effect size measures were considered in a multidimensional item response theory model: signed weighted P‐difference and unsigned weighted P‐difference. The performance of the effect size measures was investigated under various simulation conditions including different sample sizes and DIF magnitudes. As another way of studying DIF, the χ² difference test was included to compare the result of statistical significance (statistical tests) with that of practical significance (effect size measures). The adequacy of existing effect size criteria used in unidimensional tests was also evaluated. Both effect size measures worked well in estimating true effect sizes, identifying DIF types, and classifying effect size categories. Finally, a real data analysis was conducted to support the simulation results.  相似文献

Psychosocial factors influencing competency of children's statements on sexual trauma     

Kim TK  Choi S  Shin YJ 《Child abuse & neglect》2011,35(3):173-179

Objectives

The objectives of this study are to assess children's competence to state their traumatic experience and to determine psychosocial factors influencing the competency of children's statements, such as emotional factors of children and parents and trauma-related variables, in Korean child sex abuse victims.

Methods

We enrolled 214 children, who visited “Sunflower Children's Center” for sexual abuse. The children were aged 8-13 years. The children's parent were surveyed using questionnaires [Beck Depression Inventory (BDI), State-Trait Anxiety Inventory(STAI)] to obtain demographic information, traumatic event profiles and self-report scale. Children completed psychological measures as follows: Children's Depression Inventory (CDI), Revised Children's Manifest Anxiety Scale (RCMAS), Traumatic Symptom Checklist for Children (TSCC). The modified-Criteria-Based Content Analysis (CBCA) was used to assess children's statements. ANOVA, independent t-test, Pearson correlation were used. All statistics were demonstrated using SPSS 12.0.

Results

Modified-CBCA scores did not differ according to children's level of depression and anxiety. Children with parents who showed supportive reactions, scored significantly higher on the modified-CBCA scores than those with unsupportive parents. Children with severely depressed parents had lower modified-CBCA scores than those with less depressed parents. Modified-CBCA scores were significantly higher in participants who experienced a single traumatic event than those who had multiple events. However, the severity of sexual abuse, relationship with the perpetrator, types of disclosure, and duration of initial disclosure did not show significant differences in capability of statement.

Conclusion

In conclusion, the competence of statements in Korean sexually child sex abuse victims is related to parental emotional states and support rather than children's factors such as psychopathology or age, and appears to be more reliable with a single traumatic experience. Therefore, promoting parental support through psychoeducation is one of the most important things to be done to help children overcome psychologic trauma but also enhance the accuracy of their statement.  相似文献
