Agent-oriented pedagogies have been used in teaching concepts related to complex systems dynamics. However, little research has systematically explored the role of a strong agency-oriented focus on understanding of complex, dynamic ecological systems. This study analyzed seventh graders' (n = 216) explanations of a complex ecological scenario. The findings show that students were more likely to generate agentive than nonagentive explanations and students who adopted an agentive framing were least likely to understand the complex causal dynamics of two environmental scenarios, eutrophication in a pond and acid rain in a forest. Furthermore, students' initial inclination toward agency-oriented explanation on the assessment was predictive of their performance on a postassessment following an instructional opportunity to learn about ecosystems dynamics; a strong agency orientation corresponded to less complex interpretations of the dynamics of the ecosystems. The results suggest that a strongly agentive perspective may limit students' ability to learn complex systems dynamics and that the pedagogical advantages of agent-based approaches may not be without limitations. 相似文献

This study investigated the characteristics of students who report extremely high levels of hope. A sample of 682 students (ages 11–17) completed measures of hope, school engagement, life satisfaction, self‐worth, and mental health. Academic achievement was obtained from students’ school records. Based on their hope scores, students were divided into three groups: “extremely low” (bottom 10% of the distribution), “average” (middle 25%), and “extremely high” (upper 10%). Results indicate that students in the extremely high hope (EHH) group differed from students with average (AH) and extremely low hope (ELH) on all measures. Further, EHH and AH are associated with mental health benefits that are not found among students reporting comparatively ELH levels. Taken together, the findings support the notion that EHH in students is associated with adaptive psychological and school‐related functioning. Overall, given the superior adjustment profile, perhaps ‘‘enough hope’’ should be defined as “EHH.” 相似文献

Children’s cognitive ability and their academic achievement: the mediation effects of parental expectations 总被引:1,自引:0,他引:1
It is generally accepted that cognitive ability predicts academic achievement, and that parental involvement and expectations form part of the constellation of factors that predict their children??s academic achievement, particularly for families within the Chinese-heritage Cultures. Although a number of interactions between these parental factors have been proposed, the mediation effects of parental expectations on their children??s cognitive ability in predicting academic achievement are yet to be established. Data from 780 students from one primary school in Hong Kong and their parents were used to generate structural equation models to test the hypothesis that parental affective factors, as indicated by parental home and school involvement, parental beliefs of their children??s ability and parental expectations of their children??s academic scores, mediate the effects of student IQ score in predicting school achievement in English, Chinese and Mathematics. The results support the hypothesis that parents help their children to actualize their cognitive ability by directly communicating their academic expectations to their children. 相似文献
