Two Generalizations of the Item Discrimination Index to Multi-Score Items

Two general item analysis indices which apply to multi-score items are developed as generalizations of a popular index applicable to dichotomous items. The indices of discrimination are of two types: one based on differential difficulty and the other on net number of positive discriminations. The usefulness and limitations of each are discussed.     

School Effectiveness Indices Revisited: Cross-Year Stability

School effectiveness indices (SEIs) based on residuals from regressing test performance onto prior test performance and a socioeconomic status (SES) measure were obtained for 2 consecutive years for 431 elementary schools. The resulting SEIs were found to be reasonably stable year to year, the correlations ranging from. 34 to .66, depending on grade level (1–4) and subject (reading and mathematics). To aid in the identification of the factors that affect the stability of school achievement, correlations of the SEIs across subjects and grade levels were obtained also. It was determined that SEIs reflecting the performance of students at the same grade level were relatively stable, whether the same or different students were involved. However, SEIs reflecting the performance of students at different grade levels were very unstable. This suggests that grade-within-school effects dominate whatever global school effects operate in elementary schools. Implications for effective schools research, the design of school recognition/reward programs, and research and measurement specialists in general are discussed     

How Do Academic Disciplines Use PowerPoint?

How do academic disciplines use PowerPoint? This project analyzed PowerPoint files created by an academic publisher to supplement textbooks. An automated analysis of 30,263 files revealed clear differences by disciplines. Single-paradigm “hard” disciplines used less complex writing but had more words than multi-paradigm “soft” disciplines. The “hard” disciplines also used a greater number of small graphics and fewer large ones. Disciplines identified by students as being more effective users of PowerPoint used larger images and more complex sentences than disciplines identified as being less effective in this regard. This investigation suggests that PowerPoint best practices are not universal and that we need to account for disciplinary differences when creating presentation guidelines.     

“Dancing” Together: Infant–Mother Locomotor Synchrony

Pre-mobile infants and caregivers spontaneously engage in a sequence of contingent facial expressions and vocalizations that researchers have referred to as a social “dance.” Does this dance continue when both partners are free to move across the floor? Locomotor synchrony was assessed in 13- to 19-month-old infant–mother dyads (N = 30) by tracking each partner’s step-to-step location during free play. Although infants moved more than mothers, dyads spontaneously synchronized their locomotor activity. For 27 dyads, the spatiotemporal path of one partner uniquely identified the path of the other. Clustering analyses revealed two patterns of synchrony (mother-follow and yo-yo), and infants were more likely than mothers to lead the dance. Like face-to-face synchrony, locomotor synchrony scaffolds infants’ interactions with the outside world.     

Web 2.0 support for residents' and fellows' patient care and educational needs

This article discusses librarian support of medical education programs and patient care with blogs and wikis. Pedagogical background for using Web 2.0 tools in educational settings is explored and example applications given. A survey of health sciences libraries usage of blogs and wikis was conducted in 2009-2010. Using the results from the survey plus five years of experience using blogs and wikis at the University of Washington Health Sciences Library, best practices were compiled and are presented for guidance in establishing new blogs and wikis.     

Psychometric Properties of the Abbreviated Perceived Motivational Climate in Exercise Questionnaire

The purpose of this study was to develop an abbreviated version of the Perceived Motivational Climate in Exercise Questionnaire (PMCEQ-A) to provide a more practical instrument for use in applied exercise settings. In the calibration step, two shortened versions’ measurement and latent model values were compared to each other and the original PMCEQ using a three-group CFA invariance testing approach with previously collected exercise setting data (N = 5,427). Based on the model fit and reliability values, the 12-item version performed better than the 17-item version. The resultant 12-item PMCEQ-A’s CFA model estimates were then compared to the PMCEQ’s model values for two different, previously conducted studies of exercise settings (N = 414 and 770). The more parsimonious 12-item PMCEQ-A can be used by exercise psychology researchers to gain insight into members’ perspectives on the motivational climate and may lead to developing effective strategies to enhance members’ experiences and commitment.     

Boys,be ambitious: William Smith Clark and the westernisation of Japanese agricultural extension in the Meiji era

Abstract

This article examines the historiography related to the 1876 founding of Sapporo Agricultural College, the first institution of its kind in Japan. Focusing specifically on the involvement of William Smith Clark, who previously served as the president of the Massachusetts Agricultural College, it argues that the nascent imperial ambitions harboured by both the United States and Japan are essential to a full understanding of Sapporo’s founding, curriculum and subsequent history. Drawing on both primary and secondary sources as well as theoretical perspectives on empire, this article depicts Sapporo as one small part of a larger campaign of westernisation.     

Who is Whistling Vivaldi? How Black football players engage with stereotype threats in college

In light of the impact of negative stereotypes on student-athlete academic performance, the purpose of this paper was to conduct a qualitative study that examined how Black American male football players engage and cope with negative stereotypes at a predominantly White institution. Data were collected and analyzed from semi-structured interviews with 10 Division I Black male football student-athletes employing grounded theory methodology to examine how they experience and respond to negative stereotypes. Empirical results elucidate various strategies employed to engage with stereotype threat. These findings have implications for students, faculty, student affairs professionals in athletics, and others who frequently interact with student-athletes and are committed to reducing pernicious stigmas in higher education environments.
