This study examined gender differences in individual and cooperative (small-group) self-management training programs targeting mathematics performance. It was hypothesized that gender would interact with type of self-management training, such that girls in the individual training condition and boys in the cooperative training condition would improve less than girls in the cooperative training condition or boys in the individual training condition. As expected, girls in the individual training con- dition improved significantly less than both girls in the cooperative condition and boys in the individual condition. In contrast, boys in the cooperative training condi- tion did not differ significantly from either boys in the individual training condition or girls in the cooperative training condition. These results suggest the benefit of more cooperative self-management training interventions for classroom-wide interventions that include both boys and girls. Limitations of the study and suggestions for future research are discussed. 相似文献

The purpose of this study was to assess the agreement between two mobile cycle ergometer systems for recording high-intensity, intermittent power output. Twelve trained male cyclists (age 31.4 +/- 9.8 years) performed a single 3 min intermittent cycle test consisting of 12 all-out efforts, separated by periods of passive recovery ranging from 5 to 15 s. Power output was recorded using a Polar S710 heart rate monitor and power sensor kit and an SRM Powercrank system for each test. The SRM used torque and angular velocity to calculate power, while the S710 used chain speed and vibration to calculate power. Significant differences (P < 0.05) in power were found at 8 of the 12 efforts. A significant difference (P = 0.001) was also found when power was averaged over all 12 intervals. Mean power was 556 +/- 102 W and 446 +/- 61 W for the SRM and S710 respectively. The S710 underestimated power by an average of 23% with random errors of */[division sign] 24% when compared with the SRM. Random errors ranged from 36% to 141% with a median of 51%. The results indicate there was little agreement between the two systems and that the Polar S710 did not provide a valid measure of power during intermittent cycling activity when compared with the SRM. Power recorded by the S710 system was influenced greatly by chain vibration and sampling rates. 相似文献

We report on the development of a life sciences curriculum, targeted to undergraduate students, which was modeled after a commercially available physics curriculum and based on aspects of how people learn. Our paper describes the collaborative development process and necessary modifications required to apply a physics pedagogical model in a life sciences context. While some approaches were easily adapted, others provided significant challenges. Among these challenges were: representations of energy, introducing definitions, the placement of Scientists’ Ideas, and the replicability of data. In modifying the curriculum to address these challenges, we have come to see them as speaking to deeper differences between the disciplines, namely that introductory physics—for example, Newton''s laws, magnetism, light—is a science of pairwise interaction, while introductory biology—for example, photosynthesis, evolution, cycling of matter in ecosystems—is a science of linked processes, and we suggest that this is how the two disciplines are presented in introductory classes. We illustrate this tension through an analysis of our adaptations of the physics curriculum for instruction on the cycling of matter and energy; we show that modifications of the physics curriculum to address the biological framework promotes strong gains in student understanding of these topics, as evidenced by analysis of student work. 相似文献

AbstractThe current investigation aimed to determine whether there are differences in ball velocity and 3D kinematics when performing maximal kicks with the dominant and non-dominant limbs. Seventeen male academy soccer players performed maximal speed place kicks with their dominant and the non-dominant limbs. The 3D kinematics of the lower extremities were obtained using a 10-camera motion capture system operating at 500 Hz. Hip, knee and ankle joint kinematics were quantified in the sagittal, coronal and transverse planes and then contrasted using paired t-tests. Significantly higher ball velocities were obtained with the dominant limb. Foot linear velocity and knee extension velocity at ball contact were also found to be significantly greater in the dominant limb. That reduced ball velocities were observed between kicking limbs highlights the potential performance detriments that may occur when kicking with the non-dominant limb; thus, it is recommended that additional bilateral training be undertaken in order to attenuate this and improve overall kicking performance. 相似文献

Abstract This article examines the current preoccupation with enhancing the employability of graduates through the adoption of generic key skills into the undergraduate curriculum. It looks at the evidence for seven assumptions commonly made by those who promote the ‘employability’ agenda, and raises questions about the security of these assumptions including the transferability of key skills to employment contexts, the cost effectiveness of developing key skills in Higher Education rather than in employment and the competitive market advantage that individual students are believed to obtain. It concludes that in the absence of major changes to the funding regime there is unlikely to be a radical change to the curriculum and that more attention should now be paid to the post‐graduation/induction period than to the pre‐graduation stages. 相似文献

A person-centered approach to personality focusing on types of persons defined by profiles of traits is applied to childhood personality development. In 28 diverse samples of 3-, 4-, 5-, and 6-year-olds, three personality types, labeled resilient, overcontrolled, and undercontrolled, are identified. In two longitudinal samples, the undercontrolled type was related to intellectual decline over a period of six years. Both stability and change in childhood personality type were observed in longitudinal analyses. The number of risks characterizing a child's family predicted change in personality type over a two-year interval. Finally, personality type was found to be a moderator of the association of Head Start participation with cognitive development and behavior problems in childhood. The implications of personality type for understanding childhood development, particularly in children facing adversity, are considered. 相似文献
