Relations Between Instructional Practices and On-Task Behavior in Classrooms Serving American Indian Students

Achievement disparities between American Indian students and non-American Indian peers are persistent and well documented. Student engagement is a promising target for intervention given its relation to academic achievement. This study investigated the relation between specific teacher practices (opportunities to respond [OTRs], praise, and reprimands) and classroom on-task behavior in an urban, public K–8 school that serves primarily American Indian students. OTRs and praise were positively associated with student on-task behavior, whereas reprimands were negatively associated with on-task behavior. Results from multilevel logistic regression indicated that OTRs significantly increased the likelihood that a classroom was highly on-task, whereas the reprimands significantly decreased the likelihood. Praise did not have a significant effect after controlling for the other variables in the model. Results are interpreted in a context of evidence-based instructional practices for increasing OTRs and praise, decreasing reprimands, and ultimately enhancing on-task behavior in an urban classrooms serving primarily American Indian youth.     

Serious metaphysics and the vindication of reductions

What would be sufficient to show of some apparently higher-level property that it is ‘nothing over and above’ some complex configuration of more basic properties? This paper defends a new method for justifying reductions by demonstrating its comparative advantages over two methods recently defended in the literature. Unlike its rivals, what I’ll call “the semantic method” makes a reduction’s truth epistemically transparent without relying on conceptual analyses.     

IMPLICATIONS OF INTERPERSONAL NEUROBIOLOGY FOR A SPIRITUALITY OF COMPASSION

Interpersonal neurobiology (IPNB) is a burgeoning interdisciplinary field that focuses on ways in which relationships shape and transform the architecture and functioning of the human brain. IPNB points to four specific conditions that appear to encourage the emergence of empathy. Further, these conditions, when gathered together, may constitute the core components of a spirituality of compassion. Following definitions and a discussion of interdisciplinary method, this essay delineates IPNB's main tenets and demonstrates ways in which IPNB sheds light on important aspects of human empathy and compassion. Drawing on this analysis, it introduces the four conditions that encourage the emergence of empathy in individuals and groups and shows why they may be central elements of a spirituality of compassion. A case study, in which the Native American Ojibwe practice of the talking circle is described and assessed through the lens of the IPNB‐derived spirituality of compassion, demonstrates the evaluative usefulness of this set of conditions.     

Law, Convention and Objectivity: Comments on Kramer

Since I do not disagree with the line of argument taken by Kramer and the distinctions he draws between the different ways rules can be ‘mind-independent’, my comments focus on some of the complexities involved in the application of his distinctions. I suggest that law, properly understood as a system of rules/conventions is both existentially and observationally weakly mind independent, but nonetheless objective.

快速节俭启发式——相关争议与简短评论

在有限理性和生态理性假设基础上,Gigerenzer教授和在他指导下的“ABC研究组”发现并提出了再认启发式、采纳最佳启发式、优先启发式、道德启发式等一系列“快速节俭启发式”。大量研究表明这些简单决策规则是节省信息的合理而高效的认知策略,但也有一些研究者对它们表示怀疑。在本文中,作者对近期关于快速节俭启发式的一般争议及围绕采纳最佳启发式、优先启发式、道德启发式展开的具体争议进行了回顾与总结,给出了简短的评论。快速节俭启发式是一个富有前景、却又布满荆棘的研究领域。要想实现宏伟的研究目标,ABC研究组尚需做出更多、更大的努力。     

Ignorance or integration: the cognitive processes underlying choice behavior

The fast‐and‐frugal heuristic framework assumes noncompensatory tools for human preferences (i.e., priority heuristic) and inferences (i.e., take the best heuristic). According to this framework, these heuristics predict choice behavior as well as model the cognitive processes underlying such behavior. The current paper presents two studies that juxtapose predictions derived from these two simple heuristics with alternative predictions derived from compensatory principles. Dependent measures that included reaction time, choice pattern, confidence level, and accuracy were better predicted by compensatory indices than by noncompensatory indices. These findings suggest that people do not rely on limited arguments only, but tend to integrate all acquired information into their choice processes. This tendency was replicated even when the experimental task facilitated the use of noncompensatory principles. We argue that the fast and frugal heuristics can predict the final outcome only under certain conditions, but even in these particular situations they are not applicable to the processes underlying choice behavior. An integrative model for choice behavior is proposed that better represents the data. Copyright © 2009 John Wiley & Sons, Ltd.     

Naturalism, Science and the Supernatural

There is overwhelming agreement amongst naturalists that a naturalistic ontology should not allow for the possibility of supernatural entities. I argue, against this prevailing consensus, that naturalists have no proper basis to oppose the existence of supernatural entities. Naturalism is characterized, following Leiter and Rea, as a position which involves a primary commitment to scientific methodology and it is argued that any naturalistic ontological commitments must be compatible with this primary commitment. It is further argued that properly applied scientific method has warranted the acceptance of the existence of supernatural entities in the past and that it is plausible to think that it will do so again in the future. So naturalists should allow for the possibility of supernatural entities.

Studying the Practice of Cooperation and Collaboration Within an International Research Project on the Everyday Lives of Families

The aim of this paper is to analyse the sociocultural dynamics underlying collaborative research. The article is based on an international collaborative project on the everyday lives of working families in Italy, Sweden and the USA. The aim of this paper is to show that collaborative research does not necessarily produce collaboration: this is possible only with very strong rules between partners. It proposes a distinction between collaboration and cooperation, and uses this distinction to examine intergroup and intragroup joint activity. Through the analysis of the communicative exchanges occurring between researchers, the paper highlights conditions in which cooperation can become fruitful collaboration.

Simplicity and probability in causal explanation

What makes some explanations better than others? This paper explores the roles of simplicity and probability in evaluating competing causal explanations. Four experiments investigate the hypothesis that simpler explanations are judged both better and more likely to be true. In all experiments, simplicity is quantified as the number of causes invoked in an explanation, with fewer causes corresponding to a simpler explanation. Experiment 1 confirms that all else being equal, both simpler and more probable explanations are preferred. Experiments 2 and 3 examine how explanations are evaluated when simplicity and probability compete. The data suggest that simpler explanations are assigned a higher prior probability, with the consequence that disproportionate probabilistic evidence is required before a complex explanation will be favored over a simpler alternative. Moreover, committing to a simple but unlikely explanation can lead to systematic overestimation of the prevalence of the cause invoked in the simple explanation. Finally, Experiment 4 finds that the preference for simpler explanations can be overcome when probability information unambiguously supports a complex explanation over a simpler alternative. Collectively, these findings suggest that simplicity is used as a basis for evaluating explanations and for assigning prior probabilities when unambiguous probability information is absent. More broadly, evaluating explanations may operate as a mechanism for generating estimates of subjective probability.
