Peter Wylie is a man of many contradictions: a statistician and a storyteller, an introvert who loves an audience, and a self-described data geek with a passion for his work and the people it helps. Wylie is one of the pioneers of predictive modeling, the statistical analysis that uses data to drive educational institutions and nonprofits toward…

Null hypothesis significance testing has dominated quantitative research in education and psychology. However, the statistical significance of a test as indicated by a p-value does not speak to the practical significance of the study. Thus, reporting effect size to supplement p-value is highly recommended by scholars, journal editors, and academic…

This paper describes three spreadsheet exercises demonstrating the nature and frequency of type I errors using random number generation. The exercises are designed specifically to address issues related to testing multiple relations using correlation (Demonstration I), t tests varying in sample size (Demonstration II) and multiple comparisons…

With the reauthorization of No Child Left Behind, school systems must ensure students with disabilities receive instruction in general education classrooms. Implementing the inclusion model has been challenging for many school systems as the systems try to find ways to meet the needs of their diverse student populations. The purpose of this…

The principal purpose of the report for the "Florida School District Adult and Technical Centers" is to provide timely, accurate, and comparative information about the Florida School District Adult and Technical Centers System. This report is intended for use by people who are interested in data relevant to education in the School…

We apply a "tutorial design process", which has proven to be successful for a number of physics topics, to design curricular materials or "tutorials" aimed at improving student understanding of important concepts in a university-level introductory materials science and engineering course. The process involves the identification…

This article reports on a study that explored whether diversity experiences influence students' attitudes toward literary activities during the first year of college. Interactional diversity and attending a diversity workshop had a positive net influence on the outcome measure. Exposure to curricular diversity, however, had only a chance effect on…

The authors describe an observational and analytic methodology for recording and interpreting dynamic microprocesses that occur during social interaction, making use of space--time data collection techniques, spatial-statistical analysis, and visualization. The scheme has three investigative foci: Structure, Activity Composition, and Clustering.…

This study used both focus groups (qualitative) and survey data (quantitative) to develop and expand an instruction program for GIS services. It examined the needs and preferences faculty and graduate students have for learning about GIS applications for teaching and research. While faculty preferred in person workshops and graduate students…

This study investigated contemporary Japanese college students' attitudes towards Japan English (JE) and American English (AE) through a verbal guise test (VGT) as well as a questionnaire. Forty-four Japanese college students listened to four Japanese and four North Americans reading a text in English, rated them in terms of solidarity-related…

This study supported associations between three theoretically driven conceptualizations of racial and ethnic identity (REI; Multigroup Ethnic Identity Measure; Multidimensional Racial Identity Measure; Bicultural Identity Measure) and with adaptive functioning among Canadian indigenous adolescents in middle school to high school. Age differences…

Research over the past two decades has shown the alignment of teachers’ instruction with state standards is generally weak. Proposing that alignment is a useful measure of teachers' curricular knowledge (Shulman, 1986), this study uses a large database of teacher reports of their content coverage to understand the relationship of teacher…

This quantitative investigation examined the influence of low and high self-efficacy on candidate teacher academic performance in a foreign language teaching methodology course through testing the speculation that high self-efficacy levels would improve pedagogical-content knowledge (PCK). Positivism guided the research design at the levels of…

This research study examined the development of 43 preservice elementary school teachers' conceptual understanding of place value after participating in a research-based constructivist unit of instruction in place value. The preservice teachers were enrolled in one of three terms of an elementary mathematics methods course in a private midwestern…
