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.     

"This won't take long…": Interviewing,ethics and diversity

In this paper, the focus is on one particular research project, conducted in the UK, which studied the role of parent groups and organizations in relation to the mainstream education system. The authors seek to analyze and evaluate access to the different "structures of feeling" inhabited by the various respondents involved in the project. Using the project as a lens, a critical case, the relationships between respondents and researchers are problematized, highlighting a number of issues with broad applicability. These include negotiating access, securing informed consent, the debates around symmetry and asymmetry between researcher and respondent, the processes of interviewing, data analysis and dissemination. The authors also comment on the formation and development of relationships with respondents, trying to tease out the differences and similarities of age, race, social class, language, and gender, and to suggest how these disjunctions and connections affected the process of datacollection and analysis. Finally, the article concludes with a brief consideration of the implications for future research design and conduct of the arguments put forward.     

Latina Professor Revitalizing Historical Memory: Resistance Politics and Transformation within Teacher Education

This study focuses on how a Chicana/Latina professor contributed to the development of social consciousness with Spanish bilingual credential candidates in a Teacher Education Multiple Subject Credential Program, in California, USA. As a teacher educator, my goals were to look deeply at my teaching approach and to evaluate what the students and I were learning from the structure and contents of this course that emphasized issues on Latinos in the USA. The aims for evaluating my teaching both on theoretical and practice levels were to provide insights into the potential tensions in teaching a highly political course within Teacher Education, to explore implications for faculty in Teacher Education, and to investigate how bilingual Teacher Education programs can prepare future teachers to question and challenge inequities in school settings.

基于规模和集群之上的企业技术创新行为研究

本文主要研究了企业规模以及集群对于企业技术创新水平的影响。首先分析了企业规模和集群各自对企业技术创新水平的作用，在此基础上，研究了两者对企业技术创新水平的共同影响，提出了一个“企业技术创新水平的无差异曲线模型”，并进行了简要的实证分析和检验。文章的结论主要为：存在一个阀值，以此为转折点，企业规模和技术创新水平的关系呈倒“U”型；集群度对于技术创新水平有正向影响，但是边际贡献递减；集群度越高，集群内企业规模阀值就越大；规模和集群度两者共同对企业技术创新水平的影响呈“无差异曲线”形态。

论鲁迅的自省精神

对鲁迅而言,内心的孤独寂寞使他走向自由的思想。自由的思想对他来说,并不是理论的概念系统和逻辑框架,而是生存体验与记忆,对生命与宇宙的直面与承担。鲁迅的自省颠覆一切权威与偶像,撕去一切假面与伪装,直面人生,亦直面自我,坦诚暴露自己的丑恶。在不断对抗丑恶的社会和国民精神的蒙昧中,也不断审视自我心灵的创伤和痛苦,便将自省走出他的缠绕,深契入自我生命的体验,追问生命的存在及意义。时下的学只强调鲁迅的“中间物”思想是不完整的,在鲁迅对人生终极价值的自省中,“承受”思想更为重要。     

斜坡稳定分析的解析法

假定斜坡的滑移面为直线,用极限平衡法推导了倾斜边坡的临界高度和临界坡角,解出了倾斜边坡中安全系数最小的滑动面的位置,确定了边坡中稳定土体的临界角度.结果用解析式表达,为边坡的稳定分析和设计提供了可靠的理论依据.
