The Cognitive Consequences of Collaborative Problem Solving With and Without Feedback 总被引:3,自引:0,他引:3
The goal of this research was to assess the impact of feedback, partner, and shared understanding in the course of problem solving. A sample of 180 6- to 9-year-olds was pretested to discover the children's "rule" for predicting the movement of a mathematical balance beam. For the treatment they either worked alone or with a partner who was equally, less, or more competent, with two-thirds receiving feedback from the materials. They subsequently participated in 2 individual posttests. The results revealed that children receiving feedback improved significantly more than those who did not, but that the presence of a partner was only beneficial when children received no feedback. Irrespective of feedback, those children whose partner exhibited higher-level reasoning were far more likely to benefit from collaboration than those whose partner did not, provided that the pair achieved shared understanding. 相似文献

At the college level, the effectiveness of active-learning interventions is typically measured at the broadest scales: the achievement or retention of all students in a course. Coarse-grained measures like these cannot inform instructors about an intervention''s relative effectiveness for the different student populations in their classrooms or about the proximate factors responsible for the observed changes in student achievement. In this study, we disaggregate student data by racial/ethnic groups and first-generation status to identify whether a particular intervention—increased course structure—works better for particular populations of students. We also explore possible factors that may mediate the observed changes in student achievement. We found that a “moderate-structure” intervention increased course performance for all student populations, but worked disproportionately well for black students—halving the black–white achievement gap—and first-generation students—closing the achievement gap with continuing-generation students. We also found that students consistently reported completing the assigned readings more frequently, spending more time studying for class, and feeling an increased sense of community in the moderate-structure course. These changes imply that increased course structure improves student achievement at least partially through increasing student use of distributed learning and creating a more interdependent classroom community. 相似文献

This study investigates attributional beliefs of Singapore secondary students in their English study and how they can be predicted by self-construal, competence and achievement goals. A total of 1,496 students were administered surveys on seven attributions, independent and interdependent self-construals, previous achievement, self-efficacy, mastery approach and avoidance goals and performance approach and avoidance goals. We found that Singapore students attributed academic success mainly to internal regulation (effort, interest and study skills), followed by teachers’ help, ability, parents’ help and tuition classes. Hierarchical regression analyses showed that three predictors (self-construal, competence and achievement goals) explained 4.2–12.3% of the variances in students’ attributional beliefs. In particular, students with interdependent self-construal, high competence or mastery goals tended to attribute academic success to internal regulation (effort, interest and study skills) and support from teachers and parents. Students with low competence, high mastery avoidance goals or high performance goals were more likely to value tuition classes, and those with high performance avoidance goals also tended to ascribe academic success to ability and parent’s help. The findings are discussed in relation to the culture of Singapore. 相似文献

OBJECTIVES: To explore pediatricians' attitudes and experiences with the court system in child maltreatment cases. DESIGN: An anonymous, cross-sectional survey of a random sample of pediatricians registered with the North Carolina Medical Board. RESULTS: The response rate of the study was 60% (N=270). Few pediatricians (10%) reported that they had "ever" suspected maltreatment but decided not to report it. Pediatricians were equally likely to recall positive and negative experiences in court for child abuse cases. Pediatricians with negative court experiences were more likely to view reporting as time-consuming and were more than twice as likely not to report suspected cases of maltreatment (OR 2.4, 95% CI 1.04, 6.0). Seventy-five percent of pediatricians felt that court is harmful or distressing for children. CONCLUSIONS: The majority of pediatricians report suspected cases of child maltreatment. Pediatrician's court experiences play a role in the response to child maltreatment cases, influencing attitudes towards the legal system and the process of caring for maltreated children. Future research efforts should address physicians' concerns about the impact of court on children, ways to improve the working relationship between the legal system and physicians, and the training needs of physicians in child maltreatment, including testifying and understanding the court process. 相似文献

OBJECTIVE: The purpose of this longitudinal study was to determine whether there were differences in child abuse potential among mothers who were nonusers, drug users who accepted treatment, and drug users who rejected offers of treatment, over the first 2 years of their children's lives. METHOD: Participants were mothers of 140 infants, classified into Nonuser (n = 48), Treatment (n = 72), or Refuser (n = 20) groups. The Child Abuse Potential (CAP) Inventory [Milner, J. S. 1980. The Child Abuse Potential Inventory: Manual. Webster, NC: Psytec Corporation] was administered when infants were 4, 9, 12, 18, and 24 months. RESULTS: Results of mixed-model analyses of variances showed no group differences on CAP Inventory abuse scale scores. There were significant group differences in lie scale scores on the CAP Inventory, such that lie scale scores for the Nonuser group were significantly higher than lie scale scores for the Treatment group. CONCLUSIONS: Overall, results support the position that low-income women with many risk factors in their lives are at high risk for potential child abuse, but that their drug use status and drug treatment status does not differentiate them from their nonuser peers from a similar social and demographic background. 相似文献
