The relationship among achievement goals,standardized test scores,and elementary students’ focus in school

The study examined whether an academic, social, or both an academic and social focus might relate with achievement goals and academic achievement. Participants were 412 urban elementary school students. Results suggest that students with an academic focus toward school have more mastery‐approach and less mastery‐avoid achievement goals. Academic achievement (standardized test scores) did not relate with boys’ or girls’ focus toward school. These findings suggest that academic motivation, but not achievement, correspond with self‐perceptions of school as being a place to learn or school as a place for social interactions.

环境、能源、R&D与经济增长互动关系的研究

选取了1998~2012年中国31个省市的面板数据,采用面板协整方程、PVECM模型和PVAR模型,探讨了中国环境、能源、RD与经济增长之间的互动关系。结果表明:环境污染、能源消耗、RD和经济增长之间存在长期的均衡关系,且短期波动偏离长期均衡的正向调整幅度为0.69%;RD主要得益于经济发展,虽然RD水平的提高能够在一定程度上抑制环境污染,但是其却在一定程度上刺激能源消耗;虽然,能源消耗既是经济增长的动力,也是造成环境污染的重要原因,但是其能够在一定程度上促进RD水平的提升;环境污染具有累积效应和路径依赖的特性,且其对经济增长的贡献和对RD的"倒逼"作用相对有限。     

两性和谐:《金色笔记》所预言的终极世界

多丽斯·莱辛的《金色笔记》自1962年出版之日起就引来了众多评论家的关注。然而,评论家就这部作品究竟可否称为女性主义作品颇有争议。通过分析其中的女性形象和两性关系着手,可以看到莱辛的高瞻远瞩,她超越了当时的两性战争,给我们预言了未来社会两性和谐共处的这样一幅蓝图,而这已被验证正是当代女性主义者的终极关怀。

College Student Perceptions of The (In)Appropriateness and Functions of Teacher Disclosure

This study investigated college student perceptions of the (in)appropriateness of instructor disclosures and perceived functions of instructor disclosures. An interpretive analysis of 35 college students identified that family relationships, life experiences and background, and everyday talk and activities were forms of appropriate disclosures; whereas, intimate relationship details, personal problems, personal opinions, and drinking behavior were considered inappropriate topics for instructors to disclose. In terms of the function of instructor disclosures, students perceived that these disclosures worked to humanize instructors, make instructors approachable, and create affect for instructors and courses. Implications and future research are also discussed.     

Mentoring preservice teachers: identifying tensions and possible resolutions

Tensions can occur in the mentor–mentee relationship during school-based professional experiences that require problem solving. What are the tensions for mentor teachers in preservice teacher education and how might these tensions be resolved? This qualitative study collected data from 31 high school mentor teachers about tensions experienced with preservice teachers during professional experience programmes. Three themes emerged around the causes of tensions (low- to high-level conflicts) within the mentor–mentee relationship, namely: (1) personal issues (i.e. incompatibility, personality differences, language); (2) pedagogical issues (i.e. lack of pedagogical and content knowledge, differences in teaching styles); and (3) professional issues. Strategies to resolve these tensions include: maintaining a positive professional relationship, regular feedback as a way to address issues, sharing responsibility and empowerment, and using empathy for specific situations. As a theoretical contribution, this study provides a model around low- and high-level conflict associated with personal, pedagogical and professional (3Ps) issues. The study focused on mentors only and further research is required about the tensions preservice teachers experience with their mentors and ways in which these tensions can be resolved.
