Twenty-four female mice from two inbred strains, BALB and C57BL, were tested for emotional behavior. Half of the animals had successfully raised their first litter to weaning, while the other half had eaten their first litter. Cannibalistic females of both strains were found to be more prone to auditory stress than controls. However, the relationship between emotional defecation and cannibalism was found to interact with strain, suggesting an optimum level of arousal. 相似文献

The focus of this study was on the investigation of a laboratory instructional program on electricity designed for conceptual
development using constructivist principles for conceptual change. This approach was compared with a traditional laboratory
approach in a quasi-experimental design. The sample was 247 grade 10 students (boys) in a large non-government urban school.
Covariance analysis with the corresponding pretest as covariate showed statistically and educationally significant gains for
the experimental group on cognitive but not attitudinal outcomes when compared to the traditional group. Student and teacher
interview data provide some evidence for the success of the experimental approach.
Specializations: physics education, constructivist approaches to in practical work.
Specializations: science teacher education, learning environments, conceptual change. 相似文献

This analysis explores the relation between class-stratified White masculinities and moral ambiguity in FX crime drama. Conflicts between morally ambiguous White men in The Shield (2002–2008), Sons of Anarchy (2008–present), and Justified (2010–present) support colorblind racial ideology by positioning a central antiheroic protagonist in opposition to overtly racist characters who embody stereotypes associated with the White underclass. In comparison with traditional crime dramas, these juxtapositions provide realistic depictions of contemporary America by acknowledging the existence of racial prejudice while the antihero’s ultimate victory stands as a rejection of anachronistic racial sensibilities drawing attention away from issues related to systemic inequality. 相似文献

Determining the worth and effectiveness of training used within a military environment is the same accountability responsibility that educational organizations, businesses, and social agencies are charged with for improving programs and services to society. The need for accountability implies the process of evaluation, particularly in governmental training programs. This article provides a case study, blueprint, and action plan for the infusion of two evaluation models as the foundation for determining the effectiveness of training within a military application. 相似文献
