Students' emotions during homework: Structures,self-concept antecedents,and achievement outcomes     

Thomas Goetz  Ulrike E. Nett  Sarah E. Martiny  Nathan C. Hall  Reinhard Pekrun  Swantje Dettmers  Ulrich Trautwein 《Learning and individual differences》2012,22(2):225-234

In the present study (N = 553; 8th and 11th grade students; 52% female) we investigated students' enjoyment, pride, anxiety, anger, and boredom while completing homework (homework emotions), and contrasted these emotions with those experienced during class (classroom emotions). Both homework emotions and classroom emotions were assessed separately for the domains of mathematics, physics, German, and English. Our hypotheses were based on propositions of the control-value theory of achievement emotions (Pekrun, 2006), Marsh and Ayotte's (2003) differential distinctiveness hypothesis, and previous empirical findings. In line with our assumptions, observed correlations between homework emotions and classroom emotions suggested that the emotions experienced in the two settings should be assessed separately. Within domains, both homework emotions and classroom emotions showed clear linkages with students' academic self-concept and achievement outcomes, with self-concept being slightly more strongly related to classroom emotions. Between-domain relations of emotions were significantly stronger for homework emotions as compared to classroom emotions, likely due to the relative situational homogeneity of homework settings across domains. Further, between-domain relations for emotions in both settings were weaker in 11th grade students, whereas within-domain relations did not differ as a function of age. Implications for research and educational practice are discussed.  相似文献   

A determination of the dynamic response of softballs   总被引：3，自引：3，他引：0

An apparatus is described for measuring the stiffness and coefficient of restitution (COR) of balls with application to softballs. While standardized test methods currently exist to measure these properties, they do not represent the displacement rate and magnitude that occur in play. The apparatus described herein involves impacting a fixed, solid cylindrical surface (matched to the diameter of the bat) with a ball and measuring the impact force during impact and speed of the ball before and after impact. The ratio of the ball speeds determines the COR, while the impact force is used to derive a ball stiffness. For an example of the contribution of the new ball test, the performance of hollow bats, which is sensitive to ball stiffness, was compared. Bat performance showed a much stronger dependence on the proposed ball stiffness than the traditional measure. Finally, it was shown that to achieve similar conditions between impacts with fixed and recoiling objects, the impact speed should be chosen so that the centre of mass energy was the same in the two cases. The method has application to associations wishing an improved method to regulate ball and bat performance.  相似文献   

AN INVESTIGATION OF PART-TIME FACULTY COMMITMENT TO DEVELOPMENTAL ADVISING     

Pisani  Anoush M.  Stott  Nathan 《Research in higher education》1998,39(2):121-142

Part-time faculty can make substantial contributions to institutions because they represent a flexible resource that allows the institution to respond more effectively to the environment. An area of concern is whether the part-time status imparts a level of commitment to teaching that undermines educational quality. This study examines one component of part-time faculty's teaching commitment by considering their efforts toward the practice of developmental advising.  相似文献
