Development of mental attention in gifted and mainstream children: the role of mental capacity, inhibition, and speed of processing

The study examined performance of 6- to 11-year-old children, from gifted and mainstream academic programs, on measures of mental-attentional capacity, cognitive inhibition, and speed of processing. In comparison with mainstream peers, gifted children scored higher on measures of mental-attentional capacity, responded more quickly on speeded tasks of varying complexity, and were better able to resist interference in tasks requiring effortful inhibition. There was no group difference on a task requiring automatic inhibition. Comparisons between older and younger children yielded similar results. Correlations between inhibition tasks suggest that inhibition is multidimensional in nature, and its application may be affected by task demands. Measures of efficiency of inhibition and speed of processing did not explain age or group differences on a complex intellective measure of mental-attentional capacity.     

Undergraduate Physical Education Majors' Perceptions of the Roles of Teacher and Coach

Abstract

This investigation examined undergraduate physical education majors' perceptions of the roles of teacher and coach. A questionnaire was administered to a sample of 80 physical education majors at a large urban university. Subjects were asked to rate the importance of twelve characteristics or abilities for teachers and for coaches. Results indicated that the subjects viewed the abilities needed for each of the roles as similar. Subjects were asked to indicate their job preference, and to estimate their ability to perform each of the roles. Gender was significantly related to role preference, with males indicating a greater preference for the coaching role. Students indicating a preference for teaching only have less experience in athletics than the coaching only and the teaching/coaching groups.

A significant relationship was found for selected background variables with estimated role performance. The variables most highly related to confidence in one's ability to teach were positive role models and skill in a wide range of activities, and those most related to estimated ability to coach were positive role models and very high skill in at least one activity.     

Effects of student‐generated diagrams versus student‐generated summaries on conceptual understanding of causal and dynamic knowledge in plate tectonics

This research examines the beneficial effects of student‐generated diagrams versus student‐generated summaries on conceptual understanding in the domain of plate tectonics. Fifty‐eight Grade 5 students read a brief expository text about plate tectonics. During their reading of the text, students were asked to either draw diagrams, produce written summaries, or simply read the text (control). Conceptual understanding was measured by the diagrams and summaries which were generated during students' reading of the text, as well as by a posttest which assessed students' understanding of both spatial/static and causal/dynamic knowledge of the domain. Results indicated that the summaries generated during the reading of the text contained more domain‐related information than the diagrams which were generated during the reading of the text. However, on the posttest measures, the diagram group outperformed both the summary and text only groups in terms of understanding both the spatial/static as well as causal/dynamic aspects of the domain. Results are discussed with regard to the differential effects that generating diagrams as compared to generating summaries or simply reading has on both on‐line comprehension during reading and resulting conceptual understanding of the domain. © 1999 John Wiley & Sons, Inc.

Gender differences in high school students' efficacy-expectation/performance discrepancies across four subject matter domains

This study investigated gender-related differences in the efficacy-expectation/performance discrepancies of high school students across four subject matter domains. Participants (N = 131) completed American College Testing (ACT) assessments in English, mathematics, reading, and science. Additionally, prior to each domain-specific test, students rated their perceived self-efficacy expectation for successful performance on that test. As anticipated, most students reporting greater efficacy expectation also tended to perform at higher levels, particularly in mathematics. Unexpectedly, the majority of student efficacy/performance discrepancy scores fell outside the congruent range in all content areas. Approximately equal numbers of male and female students inaccurately estimated their performance capabilities, with most noncongruent students tending to fall into either the extreme overestimation/underestimation categories. Implications are discussed regarding the application of these findings to refining educational methods, and enhancing self-motivation in educational settings.     

Sex,drugs and science: the IOC’s and IAAF’s attempts to control fairness in sport

Abstract

This paper traces the history of two important policies in sport: rules against drugs and ‘ambiguous’ athletes in women’s events. We identify three phases in the work of the International Olympic Committee’s and International Amateur Athletic Federation’s medical committees: (1) from the mid-1960s to the 1970s, the medical grounding of the committees and the members’ worldviews encouraged the groups to enlist scientific techniques to solve drug use and sex ambiguity issues; (2) from the 1970s to the 1980s, administrative confusion underscored both committees, but scientific personnel gained legitimacy and furthered their own agendas; and (3) from the 1980s to the mid-1980s, the seeds of diversion in sex and drug tests were sown. The central finding of this study is that the stakeholders who shaped anti-doping and sex testing policies took for granted concerns regarding ethics and instead increasingly relied upon medical, scientific, and technical practices to define and control fairness in sport.     

Operationalizing and Detecting Disengagement Within Online Science Microworlds

In recent years, there has been increased interest in engagement during learning. This is of particular interest in the science, technology, engineering, and mathematics domains, in which many students struggle and where the United States needs skilled workers. This article lays out some issues important for framing research on this topic and provides a review of some existing work with similar goals on engagement in science learning. Specifically, here we seek to help better concretize engagement, a fuzzy construct, by operationalizing and detecting (i.e., identifying using a computational method) disengaged behaviors that are antithetical to engagement. We, in turn, describe our real-time detector (i.e., machine learned model) of disengaged behavior and how it was developed. Last, we address our ongoing research on how our detector of disengaged behavior will be used to intervene in real time to better support students' science inquiry learning in Inq-ITS (Inquiry-Intelligent Tutoring System; Gobert, Sao Pedro, Baker, Toto, & Montalvo, 2012; Gobert, Sao Pedro, Raziuddin, & Baker, 2013).
