This article discusses best-selling science books, the characteristics of the audience for popular science books, and the
role of books within science popularization and science education. Best-selling science books have been rare, but generally
readable. Regional books, also important sources of scientific information, aim at much smaller, far more price-sensitive
audiences. Many successful regional, nontechnical science books are readable, heavily illustrated, and in some cases, cross-disciplinary.
To increase the attentive audience for scientific information, improvement in science education is necessary, and the most
efficacious role for scientific institutions may be the production of materials that can be easily incorporated into school
curricula.

The authors focused on participation in extracurricular activities as a way of improving the educational outcomes of children with disabilities. Regarding students in the general population, adolescent involvement in extracurricular activities has been shown to have a positive association with school involvement and adolescent self-esteem, academic achievement, and adolescent development. Using the Educational Longitudinal Study dataset, the authors conducted logistic regression analyses to examine the relationship between participation in high school–sponsored extracurricular activities and postsecondary degree completion for students with disabilities. Findings show a statistically significant association between postsecondary degree completion for students with disabilities and extracurricular activity participation, including extent and type of extracurricular activity. Students with disabilities who participate in high school extracurricular activities may have increased likelihood of completing a postsecondary degree. Implications for policy, practice, and future research are discussed. 相似文献

This study used data from the Head Start Family and Child Experiences Survey (FACES) 2009 4-year-old cohort to examine associations among family characteristics, home and classroom environments, and the emergent literacy skills of Head Start children. Results from hierarchical linear models suggest that both family and classroom contexts play a unique and interactive role in supporting Head Start children's development of different sets of emergent literacy skills. Parental warmth was positively related to children's oral language skills (i.e., receptive and expressive vocabulary knowledge), and teachers' educational level and the quality of instructional support in the classroom were significantly associated with children's code-related skills (i.e., letter-name and letter-sound knowledge). Further, high-quality instructional support in the classroom buffered the negative influence of low maternal education on children's oral language skills. Interventions focusing on enhancing the quality of parent-child interactions, in addition to professional development for teachers designed to improve the quality of instructional support, may contribute to promoting the development of emergent literacy skills of young children from low-income families. 相似文献

This article explores recent developments inthe regulation of Internet speech, inparticular, injurious or defamatory speech andthe impact the attempts at regulation arehaving on the `body' in the sense of theindividual person who speaks through the mediumof the Internet and upon those harmed by thatspeech. The article proceeds in threesections. First, a brief history of the legalattempts to regulate defamatory Internet speechin the United States is presented; a shortcomparative discussion of defamation law in theUK and Australia is included. As discussedbelow, this regulation has altered thetraditional legal paradigm of responsibilityand, as a result, creates potential problems forthe future of unrestricted and even anonymousspeech on the Internet. Second, an ethicalassessment is made of the defamatory speechenvironment in order to determine which actorshave moral responsibility for the harm causedby defamatory speech. This moral assessment iscompared to the developing and anticipatedlegal paradigm to identify possible conformityof moral and legal tenants or to recognize theconflict between morality and law in assigningresponsibility to defamatory actors. Thisassessment then concludes with possiblesuggestions for changes in the legal climategoverning the regulation of defamatory speechon the Internet, as well as prediction of theresult should the legal climate continue todevelop on its present course. This is not tosuggest that all law, or even the law ofdefamation, be structured to reflect thesubjectivity of a moral construct, but since itis the authors position that the legalassignment of liability in online settings ismisaligned, this reflection can serve asbeginning reassessment of that assignment. 相似文献

Scientists played a key role in the first systematic introduction of nature study into North American public schools in the late nineteenth century. The initiatives of Wilbur Jackman and John Merle Coulter, affiliated with the young University of Chicago, and Liberty Hyde Bailey and Anna Botsford Comstock, at Cornell University, coincided with the "new education" reform movement that found object lessons and experience-based education superior to textbook teaching. Educational psychologists and philosophers of the 1890s, including G. Stanley Hall, related curriculum methods to perceived developmental stages in children, with a focus on immediate experience. Putting these pedagogical ideas--gained in summer institutes, normal schools, and programs at Chicago and Cornell--into practice were administrators and classroom teachers in both urban and rural classrooms. By 1900, a consensus about the value of nature study among scientists, community leaders, and teachers established it as the recognized general method of studying the natural world in public schools across much of the United States. 相似文献

The hypothesis that children develop an understanding of causal mechanisms was tested across 3 experiments. In Experiment 1 (N = 48), preschoolers had to choose as efficacious either a cause that had worked in the past, but was now disconnected from its effect, or a cause that had failed to work previously, but was now connected. Four-year-olds chose the now-connected cause more often than 3-year-olds. Experiment 2 (N = 16) showed 4-year-olds responded appropriately to an irrelevant modification in the same causal system. Experiment 3 (N = 24) demonstrated when the mechanism was batteries rather than connection, 3-year-olds could properly distinguish between relevant and irrelevant modifications. Together, these data suggest that understanding of specific causal mechanisms develops at different ages. 相似文献

Gregory Lewis Bynum 《Educational theory》2011,61(1):17-40
Immanuel Kant envisioned a kind of respect in which one recognizes each human (1) as being not fully comprehensible by any human understanding, (2) as being an end in him‐ or herself, and (3) as being a potential source of moral law. In this essay, Gregory Lewis Bynum uses this conception of respect as a lens with which to examine African American education rights on three levels: the individual level (the level of individual persons' moral experience and moral significance), the community level (the level of the formation and sustaining of social groups that have value for humanity), and the global level (the level of a universal community of humanity). Bynum's goal in this examination is to strengthen our practical understanding of African Americans' right to education defined, in accordance with international human rights documents, as the right to an education that supports the full development of the human personality in a manner that respects students' “cultural identity, language, and values.” 相似文献
