科学资源对公众科学兴趣的贡献(上)

The Contribution of Science-rich Resources to Public Science Interest(Part Ⅰ)

学校、科学中心、电视媒体、纸质媒体及网络是五种主要的公共科学教育资源。本研究以美国三座大城市的3000名成人为样本,调查了以上资源对公众科学兴趣的价值及认知倾向的作用。通过文献回顾,确定了以成人现在的科学兴趣价值观和认知倾向与其现在和过去使用相关科学资源的关系为研究目标,通过对洛杉矶、凤凰城和费城家庭样本使用CATI随机抽样得到的数据,采用主成分分析法得出最终问卷,并开展了相关人口统计学变量分析。

This preliminary study examined the effect that five major sources of public science education—schools,science centers,broadcast media,print media,and the Internet—had on adults’science interest values and cognitive predispositions.Over 3,000 adults were sampled in three U.S.metropolitan areas.By literature review,this section introduced the research question of relationship between adults’current science interest values and cognitive predispositions and the frequency of adults current and prior use of science resource.Data was collected by CATI system drawn from random samples of residents in each of the three communities:LA,Phoenix,and Philadelphia,and variables were analyzed by PCA for final items in the questionnaire,while demographic variables were analyzed at the mean time.
