Students’ conceptions of work and the understanding of the economic value of labor: a developmental study of unemployment and job precarity in times of an economic crisis     

Alonso  Lorena  Kohen  Raquel C. 《European Journal of Psychology of Education - EJPE》2023,38(3):929-944

In the aftermath of the financial and economic recession of 2008, 130 Spanish students of five age groups (8 to 17 years) and two socioeconomic backgrounds were individually interviewed about unemployment and lower wages. The participants were presented with two hypothetical situations, and their responses were qualitatively and quantitatively analyzed. The results indicated that children bring their conceptions of work when attempting to explain those phenomena. Specifically, it was found that the explanations were closely associated with the comprehension of the notion of surplus value (i.e., the idea that workers create more value than the cost of their salaries), and that the development of this notion proceeds in three levels. Younger children were simply unaware of the capacity of workers to create value (Level 1), which gave rise to some alternative conceptions (e.g., the idea that money for salaries comes from external sources). The children within the age range of 12–13 began to understand that workers create some value (Level 2). At this level, however, the notion of surplus value was not fully understood, and the idea that money for salaries comes from external sources persisted in a variety of ways. From the ages of 13–14, the children begin to understand that a wage is the price of labor and that the employer earns a profit because workers create more value than the cost of their wages (Level 3). The article presents a discussion of the possible reasons behind the slow progress observed and highlights some suggestions for educational practice.

ABSTRACT

This study modelled children’s gross motor coordination, investigated sex-differences and identified the effects of fixed and dynamic correlates on motor coordination development. A total of 344 Portuguese children (170 girls), from 6 age cohorts (5 to 9 years of age), were followed consecutively for three years (age range 5 to 11 years) using a mixed-longitudinal cohort design. Birth weight, hand dominance and socioeconomic status (SES) were identified. Gross motor coordination, body mass index, physical fitness (PF) and physical activity (PA) were assessed annually. A sequence of multilevel hierarchical linear models were developed. Model 1 found that age, age², sex, sex-by-age and sex-by-age² were significant predictors (p < 0.05) of gross motor coordination. Boys outperformed girls from 6 years of age onwards. Model 2 found a cohort effect (p < 0.05). Model 3 found that right handers were more coordinated (p < 0.05). When the confounders of body mass index, PF and PA were added to the model (Model 4) it was found that boys and girls had parallel trajectories in their gross motor coordination development. In conclusion children with increasing body mass index were less coordinated, while those who were stronger and more agile had steeper trajectories of gross motor coordination with age.  相似文献   

Teacher Implementation and the Impact of Game-Based Science Curriculum Materials

Research-based digital games hold great potential to be effective tools in supporting next-generation science learning. However, as with all instructional materials, teachers significantly influence their implementation and contribute to their effectiveness. To more fully understand the contributions and challenges of teacher implementation of digital games, we studied the replacement of existing high school biology genetics lessons over a 3- to 6-week period with Geniverse, an immersive, game-like learning environment designed to be used in classrooms. The Geniverse materials infuse virtual experimentation in genetics with a narrative of a quest to heal a genetic disease; incorporate the topics of meiosis and protein synthesis with inheritance; and include the science practices of explanation and argumentation. The research design involved a quasi-experiment with 48 high school teachers and about 2000 students, student science content knowledge and argumentation outcome measures, and analysis using hierarchical linear modeling. Results indicate that when Geniverse was implemented as the designers intended, student learning of genetics content was significantly greater than in the comparison, business-as-usual group. However, a wide range of levels of Geniverse implementation resulted in no significant difference between the groups as a whole. Students’ abilities to engage in scientific explanation and argumentation were greater in the Geniverse group, but these differences were not statistically significant. Observation, survey, and interview data indicate a range of barriers to implementation and teacher instructional decisions that may have influenced student outcomes. Implications for the role of the teacher in the implementation of game-based instructional materials are discussed.  相似文献   

Physical self and physical activity relationships in college women: does social physique anxiety moderate effects?   总被引：3，自引：0，他引：3  

Kowalski NP  Crocker PR  Kowalski KC 《Research quarterly for exercise and sport》2001,72(1):55-62

This research assessed whether social physique anxiety moderated the relationship between physical self-perceptions and the level of physical activity involvement in young women. Participants were 354 female students who completed the Social Physique Anxiety Scale (SPAS), Physical Self-Perception Profile, Self-Administered 7-Day Physical Activity Recall (PAR), and Leisure Time Exercise Questionnaire (LTEQ). Both physical activity measures were significantly related to the SPAS and all physical self-perceptions. Multiple regressions showed that only self-perceptions of conditioning significantly predicted PAR (R2 = .24) and LTEQ (R2 = .30). SPA did not add any unique variance in predicting activity, and no moderator effects were found for either PAR or LTEQ. Findings suggest that perception of physical conditioning is the dominant predictor of physical activity levels in young women, and social physique anxiety does not moderate this relationship.  相似文献   

Children's physical activity and physical self-perceptions   总被引：1，自引：1，他引：0

The aim of this study was to determine the relationship between physical self-perceptions and physical activity in Canadian school children aged 10-14 years. The sample consisted of 220 boys and 246 girls in grades 5-8. Physical activity was assessed by 7-day recall using the Physical Activity Questionnaire for Older Children. Self-perceptions of physical conditioning, sports competence, strength, body appearance and general physical self-worth were measured by the Physical Self-Perception Profile (PSPP). We found that boys were more physically active than girls and had higher perceptions of sport competence and strength. All PSPP scales were significantly correlated with physical activity in both boys and girls. Structural equation modelling procedures found the hierarchical PSPP model provided a good fit to the observed data, with little evidence of differences between the sexes. Analysis of five alternative structural models of the relationship between the PSPP and physical activity found the most parsimonious model to have significant pathways from both physical conditioning and sport skills to physical activity. Models for the sample as a whole, for boys and for girls were similar, accounting for an R2 of 0.27-0.29 for physical activity. Our results demonstrate that physical self-perceptions, especially physical conditioning and sport skills, are significant correlates of activity in this population.  相似文献   

Emotional intelligence profiles and learning strategies in secondary school students

The aim of this study was to analyse the relationship among emotional intelligence (EI) and learning strategies, identifying different emotional intelligence profiles and determining possible statistically significant differences in learning strategies through the identified profiles. Thousand and seventy one Spaniards secondary school students aged 14–17 participated in the study, completing the Trait Meta-Mood Scale-24 (TMMS-24) and the Cuestionario de Estrategias de Aprendizaje [Learning Strategies Questionnaire] (LSQ). Cluster analysis identified four differentiated EI profiles: a group of adolescents with a low EI profile, a group with high scores in attention and low scores in repair, a high EI profile group, and a group of adolescents with predominance of low attention and high repair. The results also revealed statistically significant differences among the profiles in most of the learning strategies, in which students with high general EI and those with predominance of low attention and high repair use more learning strategies than the other groups, suggesting the importance of developing programmes of emotional skills to study in greater depth EI and its influence on students’ learning strategies.  相似文献   

Comparative analysis of academic grades in compulsory secondary education in Spain using statistical techniques     

Alejandro Veas  Raquel Gilar  Pablo Miñano  Juan Luis Castejón 《Educational studies》2017,43(5):533-548

The present study, based on the construct comparability approach, performs a comparative analysis of general points average for seven courses, using exploratory factor analysis (EFA) and the Partial Credit model (PCM) with a sample of 1398 student subjects (M = 12.5, SD = 0.67) from 8 schools in the province of Alicante (Spain). EFA confirmed a one-factor model which explains 74.44% of the variance. Cronbach’s alpha value for this factor was .94. The PCM supported the one-factor model, and an optimal fit was achieved in all of the courses. The analysis of differential item functioning showed no significant differences in any course. Equitable distribution was observed in the evolution of the difficulty indices along the measurement scale for each course. This type of analysis confirms the measurement of a single latent construct in the different topics analysed, despite addressing various theoretical and procedural contents.  相似文献   

Test-enhanced learning in third-grade children     

Antonio Jaeger  Raquel Eloísa Eisenkraemer  Lilian Milnitsky Stein 《教育心理学》2015,35(4):513-521

Several recent studies have shown that retrieval is more efficient than restudy in enhancing the long-term retention of memories. However, studies investigating this effect in children are still rare. Here, we report an experiment in which third-grade children initially read a brief encyclopaedic text twice and then either performed a cued recall test on selected target contents of the text or reread the same text twice. A final four-choice memory test about the text’s contents was administered to all children after seven days as well as tests measuring their IQ and reading skills. In the final four-choice memory test, children who took the initial cued recall test showed significantly greater performance in comparison with children who restudied the text twice (their responses were 87 and 53% correct, respectively). The results suggest that cued recall tests can elicit very robust testing effects in young children, even when complex, educationally relevant materials are used as stimuli.  相似文献
