Constructivism deconstructed 总被引:3,自引:0,他引:3
W. A. Suchting 《Science & Education》1992,1(3):223-254
This paper examines the doctrine of constructivism as presented by Ernst von Glasersfeld (1989). Part I attempts to elicit a clearer statement of the concepts, positions and arguments for the latter than is immediately available in the paper. Part II discusses the problem of intersubjectivity in constructivism. The general conclusions drawn from these sections is that the basic concepts and theses of constructivism are, mostly, at best very obscure, that there is very little argument involved, and that where there is it is quite unsatisfactory. Part III ventures an explanation of at least some of the weaknesses in the doctrine, this involving a brief independent treatment of some relevant epistemological questions. 相似文献

This case study illustrates instruction in an urban 6th‐grade classroom in which students were learning about mass, volume, and density by attempting to layer (stack) three miscible solutions with differing densities atop one another. The study examines classroom discourse and interaction on the basis of four teaching goals: (a) reaching consensus about which stacks were possible, (b) developing persuasive arguments that separated data from noise, (c) establishing social norms for collective inquiry, and (d) appreciating the epistemological status of scientific knowledge. The study traces the fate of three stacks that students claimed were possible after initial investigations with the solutions. These claims underwent a process of collective validation in which consensus without coercion was the goal, which illustrates emergent standards for backing claims with evidence, as well as for replicability, among the students. Students were successful in achieving three of the four goals, with some qualifications. In relation to Goal 3, which required generalization to other situations, somewhat less success is reported. Limitations in the current standards, difficulties of time allotment in current curricula, and establishing classroom cultures of inquiry are discussed. © 1999 John Wiley & Sons, Inc.

Self‐reported internalizing symptoms of seriously emotionally disturbed (SED) and regular education students in grades 4–6 were compared using the Internalizing Symptoms Scale for Children. All participants were African American and from an urban public school district in the Southeastern United States. Each of the two study groups consisted of 50 participants (35 boys, 15 girls) who were matched by gender and socioeconomic status. The SED group reported significantly higher levels of internalizing distress than the regular education group. In contrast to previous findings, there was no significant gender difference in self‐reported internalizing symptomatology in the present study. A discriminant function analysis found that the ISSC scores were able to correctly classify 91% of the participants into their respective educational group. Results of this study provide additional evidence of the construct validity of the ISSC, a recently developed and unique self‐report measure. Results are discussed in terms of future research needs and educational/clinical practice with students who have emotional and behavioral disorders. © 1999 John Wiley & Sons, Inc. 相似文献

This study investigates the efficacy of a social skills training program with seven mildly handicapped students across three school settings: regular classroom, special education resource room, and recess. It was found that social skills training generated improvement on both pre-post measures and behavior ratings. Improvements were maintained 2 weeks after treatment was discontinued for seven students. All students' performance generalized from resource room to regular classroom settings; only four students' performance generalized to the recess setting. 相似文献

There are many situations where random assignment of participants to treatment and comparison conditions may be unethical or impractical. This article provides an overview of propensity score techniques that can be used for estimating treatment effects in nonrandomized quasi-experimental studies. After reviewing the logic of propensity score methods, we call attention to the importance of the strong ignorability assumption and its implications. We then discuss the importance of identifying and measuring a sufficient set of baseline covariates upon which to base the propensity scores and illustrate approaches to that task in the design of a study of recovery high schools for adolescents treated for substance abuse. One novel approach for identifying important covariates that we suggest and demonstrate is to draw on the predictor-outcome correlations compiled in meta-analyses of prospective longitudinal correlations. 相似文献

This study evaluated the Gentle Warrior Program, a traditional martial arts–based intervention to reduce aggression in children, as it was implemented in three elementary schools. The sample consisted of 254 children in grades 3, 4, and 5 who participated in the Gentle Warrior Program as part of a larger school violence intervention. Results indicated that boys who participated in more Gentle Warrior sessions reported a lower frequency of aggression and greater frequency of helpful bystanding (i.e., helpful behavior toward victims of bullying) over time, relative to boys with less frequent participation. The effect of participation on aggression was partially mediated by empathy. The effect of participation on helpful bystanding was fully mediated by changes in student empathy. No significant results were found for girls. Results of the study provide preliminary support for the use of martial arts–based interventions to address bullying in schools for boys, by teaching empathy, self‐control, and peaceful strategies to resolve conflicts. © 2008 Wiley Periodicals, Inc. 相似文献

Motor performance is an important health resource. Review articles revealed a decline of motor performance of approximately 10?% between 1975 and 2006. In the past most of the data available for such comparisons came from ad hoc studies with non-standardized methods. Within the framework of the ”Motorik-Modul“ (MoMo) study as part of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), it is possible for the first time to directly compare two cohorts in the ages of 4–17 years in a nationally representative database for Germany. The aim of this article is to report changes in motor performance of children and adolescents in the time period 2003–2006 (cohort baseline n = 4528) compared to 2009–2012 (cohort wave 1, n = 2820). Overall, it is clearly shown that the motor performance of children and adolescents in Germany did not decrease within the observational period of 6 years. The comparison of mean values of the baseline cohort compared to those of wave 1 showed that 28 out of 52 mean values of the two cohorts with a high probability did not differ based on 95?% confidence intervals (CI). In 24 out of the 52 mean values positive changes could be noted based on the individual 95?% CI values. There were more positive changes in primary school aged children than in other age groups. Within these positive changes, most effect sizes were small to medium. The results indicate that recent activities aiming at elevating motor performance levels may have started to make an impact and should be expanded, also in secondary schools. The comparative cohort study presented in this article is currently being checked by the ongoing MoMo wave 2 survey of 2014–2017. 相似文献
