Do Biologists’ Conceptions of Science as a Social Epistemology Align with Critical Contextual Empiricism?

From literature on understandings of the “nature of science” (NOS), we know that sometimes scientists and others that participate in teaching and mentoring in the sciences lack an informed view of the philosophical underpinnings of their discipline. In this study, we ask whether biologists who are also teachers or mentors for college students agree with the tenets of critical contextual empiricism (CCE), a social epistemology of science that foregrounds the importance of a diversity of voices in knowledge-producing communities. We used a Q-sort methodology to examine beliefs about social knowledge construction that are related to teaching science inclusively. Overall, we found that biologists-teachers held viewpoints somewhat consistent with the tenets of Critical Contextual Empiricism. Although participants shared many beliefs in common, we found two significantly different groups of participants that were characterized under the themes “knowledge is constructed by people” and “the truth is out there.” Overall, although participants believed a diversity of cognitive resources aids scientific communities, they failed to recognize the more nuanced ways certain social interactions might impact objective knowledge production. For one group, outside of a belief that collaboration in science is valuable, other social influences on science were assumed to be negative. For a second group, the search for universal truth and the separation of rational and social aspects was critical for scientific objectivity. We use the results of our Q-sort to identify areas for professional development focused on inclusive science teaching and to recommend the explicit teaching of CCE to science educators.

     

Rational Higher-Order Belief Revision in Young Children

Belief revision can occur at multiple levels of abstraction, including lower-level and higher-order beliefs. It remains unclear, however, how conflicting evidence interacts with prior beliefs to encourage higher-order belief revision. This study explores how 4- and 5-year-olds (N = 96) respond to evidence that directly conflicts with their causal higher-order beliefs. When shown a single event that directly violated a strongly supported prior belief, preschoolers largely maintained their initial higher-order belief. However, when the prior belief was more weakly supported and the counterevidence was stronger, children changed their minds. These findings indicate that young children can revise their higher-order beliefs and, furthermore, do so depending on the strength of both the evidence and their prior beliefs.

How Effective is Example Generation for Learning Declarative Concepts?

Declarative concepts (i.e., key terms and corresponding definitions for abstract concepts) represent foundational knowledge that students learn in many content domains. Thus, investigating techniques to enhance concept learning is of critical importance. Various theoretical accounts support the expectation that example generation will serve this purpose, but few studies have examined the efficacy of this technique. We conducted three experiments involving 487 undergraduates to investigate the effects of example generation on concept learning and examined factors that may moderate its effectiveness. Students read a short text that introduced eight concepts. Some students were then prompted to generate concrete examples of each concept followed by definition restudy, whereas others only restudied definitions for the same amount of time. Two days later, students completed final tests involving example generation and definition cued recall. Meta-analytic outcomes indicated that example generation yields moderate improvements in learning of declarative concepts, relative to restudy only. Each experiment also included additional groups to investigate potential moderators. Example generation tended to be more effective with spaced versus massed restudy. Despite strong correlations between the quality of examples generated during practice and final test performance, experimental manipulations that improved example quality did not improve learning. In sum, the current work establishes that example generation enhances concept learning and provides an important foundation for further investigating factors that moderate its benefits to learning.     

Open-Skilled Sport,Sport Intensity,Executive Function,and Academic Achievement in Grade School Children

ABSTRACT

Research Findings: The present study examines connections among participation in open- and closed-skilled sports; the metabolic intensity of each sport; and executive function (EF), literacy, and math achievement in a sample of 3rd-grade children. Utilizing data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, we categorized 15 youth sports (e.g., soccer, tennis, swimming, running track) as open or closed skilled and assigned them a metabolic intensity value. Results showed that the connection between sport intensity and EF was curvilinear, with a positive association between EF and sport intensity below 25 metabolic equivalents (METs) and a negative association with METs above 25. For math, results differed for the number of open-skilled sports and the intensity of a sport, with higher intensity associated with lower math scores and playing more open-skilled sports associated with higher math scores. Literacy skills were not significantly related to sport participation. Practice or Policy: The preschool years may offer a promising opportunity to encourage participation in both complex and intense physical activity. These findings highlight domain-specific connections among sports and EF and math achievement and offer insight into connections among sport intensity (METs), the type of sports children play, and cognitive development.     

Assessment of Attention‐Deficit/Hyperactivity Disorder (ADHD): A comparative evaluation of five,commonly used,published rating scales

ADHD is one of the most common referrals to school psychologists and child mental health providers. Although a best practice assessment of ADHD requires more than the use of rating scales, rating scales are one of the primary components in the assessment of ADHD. Therefore, the goal of this paper is to provide the reader with a critical and comparative evaluation of the five most commonly used, narrow‐band, published rating scales for the assessment of ADHD. Reviews were conducted in four main areas: content and use, standardization sample and norms, scores and interpretation, and psychometric properties. It was concluded the rating scales with the strongest standardization samples and evidence for reliability and validity are the ADDES, the ADHD‐IV, and the CRS‐R. In determining which of these to use, the prospective users may want to reflect on their goals for the assessment. The ACTeRS and the ADHDT are not recommended for use because they are lacking crucial information in their manuals and have less well‐documented evidence of reliability and validity. Conclusions and recommendations for scale usage are discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 341–361, 2003.
