Nancy K. Scammacca; Anna-Mária Fall; Greg Roberts – Grantee Submission, 2015
Effect sizes are commonly reported for the results of educational interventions. However, researchers struggle with interpreting their magnitude in a way that transcends generic guidelines. Effect sizes can be interpreted in a meaningful context by benchmarking them against typical growth for students in the normative distribution. Such benchmarks…

Park, Sangwook – ProQuest LLC, 2011
Many studies have been conducted to evaluate the performance of DIF detection methods, when two groups have different ability distributions. Such studies typically have demonstrated factors that are associated with inflation of Type I error rates in DIF detection, such as mean ability differences. However, no study has examined how the direction…

Raykov, Tenko – Structural Equation Modeling: A Multidisciplinary Journal, 2011
This article is concerned with the question of whether the missing data mechanism routinely referred to as missing completely at random (MCAR) is statistically examinable via a test for lack of distributional differences between groups with observed and missing data, and related consequences. A discussion is initially provided, from a formal logic…

Turan, Selahattin; Bektas, Fatih – Eurasian Journal of Educational Research, 2013
Problem Statement: Creation of a common culture in educational organizations, particularly in schools, depends first on the presence and cohesiveness of an interacting group of individuals. Individual aims are more likely to turn into a shared objective in schools with a strong, participatory culture. Culture shared by all school stakeholders…

Wroughton, Jacqueline; Cole, Tarah – Journal of Statistics Education, 2013
Recognizing the differences between three discrete distributions (Binomial, Hypergeometric and Negative Binomial) can be challenging for students. We present an activity designed to help students differentiate among these distributions. In addition, we present assessment results in the form of pre- and post-tests that were designed to assess the…

Caulfield, Michael J. – Mathematics Teacher, 2012
What if Stephen Douglas instead of Abraham Lincoln had won the U.S. presidential election of 1860? What if John F. Kennedy had not carried some of the eight states he won by 2 percentage points or fewer in 1960? What if six hundred more people in Florida had voted for Al Gore in 2000? And what if, in that same year, the U.S. House of…

Forgasz, Helen; Leder, Gilah; Gómez-Chacón, Inés Ma – Mathematics Education Research Group of Australasia, 2012
People aged 20-39 were stopped in the streets of Victoria (Australia) and Madrid (Spain) to gauge their views on the gendering of mathematics. The findings suggested that for respondents from both countries, if stereotyped beliefs are held they were more strongly associated with the traditional male stereotype, that is, that males are considered…

Under Part B of the "Individuals with Disabilities Education Act" ("IDEA"), states must collect and examine data to determine whether significant disproportionality on the basis of race and ethnicity is occurring in the state, or its school districts, with respect to the identification, placement, and discipline of students…

Watt, Michael – Online Submission, 2016
The purpose of this study was to inform the deliberations of a policymakers' working group by investigating what key actors in the materials' marketplace are doing to align digital and print-based materials with the Australian Curriculum and what steps need to be taken to deliver aligned materials to schools. Content analysis method was used to…

Colozzo, Paola; Whitely, Cristy – First Language, 2014
This study considered the adequacy of references used by children to introduce, maintain, and reintroduce characters in complex narratives involving multiple characters. Sixty-three English-speaking Canadian children from kindergarten to second grade (M age 7.0 years) told two multi-episode stories from wordless picture books. Analyses considered…

Development of Nonword and Irregular Word Lists for Australian Grade 3 Students Using Rasch Analysis
Callinan, Sarah; Cunningham, Everarda; Theiler, Stephen – Australian Journal of Learning Difficulties, 2014
Many tests used in educational settings to identify learning difficulties endeavour to pick up only the lowest performers. Yet these tests are generally developed within a Classical Test Theory (CTT) paradigm that assumes that data do not have significant skew. Rasch analysis is more tolerant of skew and was used to validate two newly developed…

Ee, Jessie; Ong, Chew Wei – Journal of Adventure Education and Outdoor Learning, 2014
Research studies have shown that educational programmes such as camps and field trips can develop affective and social relationships through personal exposure to outdoor experiences among students. This study will illustrate the outcome of a social emotional learning camp organized for 93 Secondary Two students (mean age 14.1) in Singapore. Both…

Aliaga, Oscar A.; Kotamraju, Pradeep; Stone, James R., III – High School Journal, 2014
We examine participation in Career and Technical Education (CTE) using a typology that better reflects the CTE credit-taking experience of all public high school students, and it is based on the several changes in academic requirements that all students need to meet in order to graduate, including those considered CTE students. We argue that the…

Schueler, Beth – Society for Research on Educational Effectiveness, 2014
A series of metaanalyses have documented a notable association between family engagement with children's learning and students' academic outcomes (Fan & Chen, 2001; Hill & Tyson, 2009; Jeynes, 2003, 2005, 2007). Family-school engagement is also associated with effective school-level reform and improvement efforts. The University of Chicago…
