Batting last as a home advantage factor in men's NCAA tournament baseball

In baseball and softball, there is a rule that allows the home team to have the last at-bat and thus the final opportunity to win the game. However, in tournament play, this rule is often set aside and, instead, batting order is decided by other means (e.g. tournament rules, the flip of a coin). The purpose of this study was to examine the impact of the batting last rule on game outcome in NCAA men's regional tournament baseball. It was hypothesized that host (i.e. home) teams would win a greater percentage of the games in which they batted last compared with when they batted first. This hypothesis was not supported. Closer examination of the last inning of play showed home teams were no more likely to have won the game during their last bat than visitors playing other visitors. The results suggest that the batting last rule contributes minimally, if at all, to home advantage in NCAA tournament baseball.     

Auditory perceptual processing in reading disabled children

One hundred and three children attending Learning Assistance Centres due to reading difficulties and one hundred and three matched, average readers were administered a battery of auditory perceptual processing tasks. The battery was composed of auditory analysis and synthesis, auditory sequential memory, auditory discrimination, and phonemic segmentation tasks. A principal components analysis yielded four factors. These were determined to be advanced phonological awareness, sequential memory, discrimination, and simple phonological awareness. Discriminant analyses, using the factor scores, indicated that three of the four factors were able to discriminate between the able and disabled readers. Most notable among these was advanced phonological awareness. Auditory discrimination could not discriminate between the groups. The results suggest that there may not be one underlying phonological ability implicated in successful reading acquisition. Furthermore, it is clear that two levels of phonological awareness exist and that screening and diagnostic instruments should address both in order to have predictive validity.     

Deviant Peer Factors During Early Adolescence: Cause or Consequence of Physical Aggression?

This study investigated reciprocal relations between adolescents' physical aggression and their perceptions of peers' deviant behaviors and attitudes. Analyses were conducted on four waves of data from 2,290 adolescents (ages 10–16) from three urban middle schools. Autoregression models revealed reciprocal relations between peer factors (i.e., friends' problem behavior, peer pressure for fighting, friends' support for fighting) and adolescents' reporting of their aggressive behavior. Bidirectional relations were also found between peer pressure for fighting and adolescents' frequency of physical aggression based on teacher ratings. Findings were consistent across sex, grade, and time. Findings suggest that multiple dimensions of peers' behaviors uniquely play a role in the development of adolescents' aggression and have important implications for interventions to reduce problem behaviors.     

Prediction of the science inquiry skill of seventeen-year-olds: A test of the model of educational productivity

The study was designed to investigate the influence of student characteristics and classroom characteristics on students' inquiry skill. The sample consisted of a national stratified random sample of 1955 17-year-olds who were assessed as part of the 1981-1982 national assessment in science. The dependent variable was a 17-item measure of students' inquiry skill. The independent variables were selected from the available data using the Model of Educational Productivity as a guide in the selection of the variables. The first purpose of the study was to test the effectiveness of the Model of Educational Productivity for predicting the inquiry skill of 17-year-olds. The results of this study indicate that this model was capable of accounting for between 24 and 32% of the variance in inquiry skill for the general population of 17-year-olds. More specifically, students' reporting of their general ability alone accounted for between 17 and 22% of the variance. The second question posed by this study asked whether the prediction of inquiry skill differed for males and females. While there was some difference in the contribution of the minor predictors, there was very little difference in the prediction of inquiry skill for males and females using the Model of Education Productivity. The third question posed by this study asked whether the prediction of inquiry skill differed for white and nonwhite students. For nonwhite students, the Model of Educational Productivity accounted for only 18% of the variance in science inquiry skill. Thus, it would appear that there is a great deal that is not known about the factors that contribute to the science inquiry skill of nonwhite students.     

Special education placement decisions made by teams and individuals: A cross-cultural perspective

The present study looked at whether special education placement decisions made by teams are superior to those made by individuals. The investigation was conducted in Puerto Rico to determine whether the benefits of the cooperative group process exist in another culture. Results indicated that teams in Puerto Rico generated significantly less variability (i.e., errors) in their placement decisions than did the same specialists acting independently.     

Kinecting Physics: Conceptualization of Motion Through Visualization and Embodiment

The purpose of this work was to share our findings in using the Kinect technology to facilitate the understanding of basic kinematics with middle school science classrooms. This study marks the first three iterations of this design-based research that examines the pedagogical potential of using the Kinect technology. To this end, we explored the impact of using the Kinect in conjunction with an SDK Physical Virtual Graphing program on students’ understanding of displacement, velocity and acceleration compared to students who conducted more traditional inquiry of the same concepts. Results of this study show that, while there may be some affordances to be gained from integrating this technology, there is a need for a scaffolded approach that helps students to understand the “messiness” of the data collected. Further, meta-cognitive activities, such as reflective opportunities, should be integrated into the inquiry experiences in order to scaffold student learning and reinforce concepts being presented. While the Kinect did work to generate large-scale visualization and embodied interactions that served as a mechanism for student understanding, this study also suggests that a complementary approach that includes both the use of hands-on inquiry and the use of the Kinect sensor, with each activity informing the other, could be a powerful technique for supporting students’ learning of kinematics.
