The Efficacy of Collaborative Learning Groups in an Undergraduate Statistics Course

Abstract. Assessment of the efficacy of collaborative learning group techniques is frequently subjectively based and often relies on casual comments from students or faculty. Despite this shortcoming, instructors searching for new and effective ways of teaching quantitative courses continue to experiment with collaborative pedagogy. This study examined the relationship between student performance on collaborative learning group assignments and students' examination scores in statistics. The results both challenge and support the efficacy of collaborative learning groups and suggest that faculty modify such techniques when evidence of student achievement cannot be empirically linked to the collaborative experience.     

The Art of Crafting Music Score Approval Plans: An Ongoing Process

Although approval plans have long been an accepted tool for monographic collection development, they have seen comparatively slow adoption for music scores. This slow adoption is mirrored by a relative dearth of literature about music score approval plans. At a time when changes in the financial and publishing landscape are having a profound impact on collection development practices and current trends in organizational restructuring are placing greater demands on librarians' time, the need for contemporary discussion of approval plans is that much greater. This article discusses the ups and downs of one library's foray into music score approval plans.     

The “coherent majority average” for juries’ evaluation processes

Abstract

I propose a method to synthesize the performance scores for artistic sports such as rhythmic gymnastics, figure skating, synchronized swimming, and diving by taking into account inter-judge variability, while maintaining all the reliable scores. This procedure is based on the assumption that the majority of the scores in each event are reliable and they relate well to those scores that are closest to them. The method consists of putting scores in order and considering clusters of m consecutive scores, where m is the number of judges making up the simple majority. For each cluster, the difference between the highest and the lowest score is calculated. In cases where the minimum difference is positive, the arithmetic mean of those scores that belong to clusters where the difference is minimal is computed. In cases where the minimum difference is zero (i.e. if the majority of judges unanimously assign the same score), then the set of the scores to consider within the mean is extended to those scores that are very near to those of the majority of the judges. A comparison between the actual evaluation procedures and the proposed model is provided.     

The Impact of Girls' Interscholastic Sport Participation on Academic Orientation

Abstract

This study was designed to assess the influence of athletics and other extracurricular activities on the academic orientation of female high school students. Senior girls were categorized into groups—labeled athlete-only (comprising students who participated only in athletics as an extracurricular activity), service-only (students who participated in service activities only), athlete-service (students participating in both) and neither (students whose extracurricular activities included neither athletics nor service activities). Categorizations were based on listings from their high school yearbooks. Those taking the ACT college entrance exam (N = 487) were compared on composite and English scores to the other groups, and to national and state averages. Analyses of covariance, controlling for SES and extent of activity involvement revealed that the athlete-only group recorded the lowest average scores, but these could not be attributed to the participation category to which they belonged. Rather, socioeconomic level and extent of activity involvement were factors contributing to most of the differences between groups in which higher SES levels and higher levels of involvement were predictive of higher ACT scores. Moreover, none of the groups' scores were significantly different from national or slate averages. These results refute the notion that involvement only in athletics is detrimental to educational achievements for females, and lead to certain recommendations for longitudinal, multi-measure investigations of academic orientations.     

A Method for Identification of Some Components of Judging Springboard Diving

Abstract

This article presents a method to analyze the scoring of judges in springboard diving by identifying some of the components of a dive which are useful in predicting the scores of the judges. A videotape recording of 26 divers doing the front dive half-twist was made at the 1979 men's A.A.U. prequalifying meet, held at Ohio State University. The method of measurement involved the use of clear plastic grids placed over the video monitor. The maximum height of the diver above the board, distance out from the board, size and duration of splash, numerous body angles at various times during the dive, as well as deviation of twist from 180 degrees were measured. A Stepwise Multiple Regression program was used to generate a prediction equation using a subset of these variables which would best predict the total score of the judges for each dive. The equation generated included height, distance, twist, and lower body angle at the point when the diver's head was opposite the board; the equation predicted the scores of the judges with a multiple correlation coefficient R = .80. The particular variables identified would of course be different for other types of dives, and might very well differ for a new set of data for the front dive half twist. However, the method presented provides the diving community with a procedure for identifying some of the components in a particular dive that partially explain what is in the judge's mind.     

Does the Opportunity–Propensity Framework predict the early mathematics skills of low-income pre-kindergarten children?

Prior studies have shown that the variables described in the Opportunity–Propensity (O–P) Framework have successfully accounted for the mathematics and science achievement of students in grades 1–3 and 8–12. The two goals of the present study were to (1) determine whether the O–P Framework could also account for individual differences in the early mathematics skills of low-income, pre-kindergarten children and (2) determine whether latent variables constructed from measured variables would account for performance in the manner specified in the O–P model. The O–P Framework assumes that high achievement in mathematics is a function of three categories of factors: (a) antecedent factors, variables that operate early in a child’s life and explain the emergence of opportunities and propensities, (b) opportunity factors, variables that measure a child’s opportunity to learn mathematics content at home and school, and (c) propensity factors, variables that capture a child’s propensity for learning in terms of self-regulation, motivation, and prior cognitive skills. To test the fit of this model for low-income children during the year before they attend kindergarten, the authors conducted a secondary analysis of achievement and background data from the Early Childhood Longitudinal Study-Birth (ECLS-B) Cohort data set. Structural equation modeling indicated significant associations between the antecedent factor, opportunity factor, and propensity factor, and between the opportunity factor and pre-kindergarten mathematics achievement. The results confirmed the fit of the model and identified the kinds of learning experiences that could promote the acquisition of mathematics skills in low-income children and improve their readiness to learn in first grade and beyond.     

The Influence of Communication Apprehension on Superiors' Propensity for and Practice of Participative Decision Making

This investigation examined if traitlike communication apprehension (CA) serves as a significant predictor of superiors' propensity for and practice of participative decision making (PDM)—that is, involving others in decision-making processes. A total of 219 superiors recruited from a variety of organizations served as participants in this study. Results revealed that traitlike CA is a significant determinant of variation in superiors' inclination for, as well as their actual practice of, PDM. These findings suggest that superiors with lower CA possess favorable perceptions of PDM and are more inclined to involve others in decision-making processes than their colleagues with higher CA. Conversely, results suggest that superiors with higher CA typically possess less favorable perceptions of PDM and are less likely to involve others when making decisions. Theoretical and practical implications underpinning these results are explored. Future research directions are also proposed.
