Students’ emotions during homework in mathematics: Testing a theoretical model of antecedents and achievement outcomes

The experience of pleasant and unpleasant emotions in academic situations is known to affect students’ learning. The aim of the present study was to extend previous research by examining the antecedents and consequences of student emotions in the homework context. Multilevel analyses of a longitudinal dataset containing 3483 grade 9 and grade 10 students in 155 classes showed that the perceived quality of the homework tasks assigned by the teacher affected students’ experience of unpleasant homework-related emotions. Moreover, the experience of unpleasant emotions during homework sessions was negatively related to homework effort and negatively predicted later achievement in mathematics.     

The relationship between homework time and achievement is not universal: evidence from multilevel analyses in 40 countries

Although homework is generally believed to be an important supplement to in-school learning, research has not yet fully clarified the relationship between homework and achievement. This cross-cultural study analyzed the relationship between homework time and mathematics achievement drawing on data from 231,759 students in 9,791 schools and 40 countries who participated in the Programme for International Student Assessment (PISA) 2003. Multilevel analyses found a positive association between school-average homework time and mathematics achievement in almost all countries, but the size of the association decreased considerably once socioeconomic background and school track were controlled. At the student level, no clear-cut relationship was established between homework time and achievement across the 40 countries. The results highlight the need to use multilevel analyses and to control for confounding variables in homework research.     

Finite element simulation of pole vaulting

Pole vaulting is one of the most spectacular disciplines in athletics. The evolution of world record heights is strongly influenced by the development of advanced poles and subsequent materials. Employing advanced, load-adjusted composites has resulted in a steady increase of the world record height. This study provides a framework for finite element simulations of pole vaulting with focus on the initial and boundary conditions as well as finite element choices. The influence of the pole bending stiffness on the achievable height is systematically simulated. Higher effective bending stiffness leads to higher pole vaulting heights. However, if a certain stiffness is exceeded, the vaulter will not be able to bend the pole enough which leads to failed attempts.     

Hochintensives Intervalltraining im Sportunterricht

Background and aim

This study examined the effects of a 6-week high-intensity interval training (HIIT) vs. low-intensity endurance training (LOW), applied during physical education on motor performance, mood and perceived exertion.

Methods

Over a period of 6 weeks, 85 pupils (34 male; 51 female; age: 11.9?±?0.9 years) performed 11 sessions of either HIIT (20?min, intervals from 10?s to 4?min at about 90–100% of average running speed of 6?min run [v_mean]) or LOW (30?min, intervals from 6–25?min at about 65–85% v_mean). Before and after the 6?week intervention each pupils’ anthropometry and motor performance (20?m sprint, standing long-jump, lateral jumping from side to side, push-ups, sit-ups, 6?min run) were assessed. Session rating of perceived exertion (RPE) was recorded after each session and mood was assessed by questionnaire following the 3rd, 6th, 9th and 11th session.

Results

RPE (p?<?0.05) was higher and mood more positive (p?<?0.05) with HIIT compared to LOW. Performances in the 6?min run (p?<?0.001; part. η²?=?0.473), 20?m sprint (p?<?0.001; part. η²?=?0.226), standing long-jump (p?<?0.05; part. η²?=?0.056), push-ups (p?<?0.001; part. η²?=?0.523) and sit-ups (p?<?0.001; part. η²?=?0.146) improved following HIIT and LOW with no significant time?×?group interaction (except for the sit-ups [p?<?0.05; part. η²?=?0.048]).

Conclusions

HIIT and LOW improved the performances in 6?min run, 20?m sprint, standing long-jump and push-ups similarly. However, the improvements in HIIT compared to LOW were achieved in 30% less time. As time is limited in physical education classes, HIIT offers a new perspective for improving endurance and motor performance in children. The positive mood associated with HIIT demonstrates the applicability in physical education.

     

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

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.     

Educational usage of Facebook and academic achievement in distance university students: Mediated by basic needs satisfaction
