Longitudinal study of a cooperation-driven,socio-scientific issue intervention on promoting students’ critical thinking and self-regulation in learning science

ABSTRACT

This longitudinal study explored the effects of a Cooperation-driven Socioscientific Issue (CDSSI) intervention on junior high school students' perceptions of critical thinking (CT) and self-regulation (SR) in Taiwan. Forty-nine grade 7 students were randomly selected as an experimental group (EG) to attend a 3-semester 72-hour intervention; while another 49 grade 7 students from the same school were randomly selected as the comparison group (CG). All participants completed a 4-wave student questionnaire to assess their perceptions of CT and SR. In addition, 8 target students from the EG with the lowest scores on either CT or SR were purposefully recruited for weekly observation. These target students and their teachers were interviewed one month after the intervention in each semester. Analyses of covariance and paired-wise t-tests revealed that the EG students' perceptions of CT and SR in learning science were improved during the study and were significantly better than their counterparts' at the end of the study. Systematic interview and classroom observation results were consistent with the quantitative findings. This study adds empirical evidence and provides insights into how CDSSI can be integrated into planning and implementing effective pedagogical strategies aimed at increasing students' perceptions of CT and SR in learning science.     

Confirmatory factor analysis of achieving the beginning teacher standards inventory

The purpose of this study was to examine the factorial validity and reliability of the Achieving the NASPE Standards Inventory (ANSI) that assesses pre-service physical education teachers' perceptions of achieving the National Association for Sport and Physical Education (NASPE) beginning teacher standards (2003). Four hundred fifty-two pre-service teachers from 15 Physical Education Teacher Education (PETE) programs voluntarily and anonymously completed the inventory. The hypothesized measurement models were analyzed by means of a confirmatory factor analysis. The Goodness-of-fit statistics indicated that the modified 3-factor model with 38 items represented a best fitting model with the data. The scores generated by the total and the 3 subscales of the 38-item ANSI demonstrated a high level of internal consistency.     

国外留学经历与大学工科生创造力的关系研究

反讽的自由主义文化——罗蒂的社会希望

罗蒂从语言的偶然性出发展开对传统镜像哲学的批判,并设想了一个反讽的自由主义文化作为社会未来之希望.这种文化中的理想成员是自由主义的反讽主义者,他们既渴望最大限度地实现私人创造,又能以“我们”意识促进公共团结.罗蒂相信,只要能区分开私人领域的语汇和公共领域的语汇,反讽的自由主义文化就有实现的可能.罗蒂的设想招致许多非议,这些非议都忽视了罗蒂提出设想的初衷和目的,罗蒂的初衷是强调理想的社会中不应该存在一个绝对的权威资源来作优劣之分的评判,他的目的是促使人们放弃对超验事物的追求,转而追求俗世的幸福.
