“Maybe I can teach those kids.” The influence of contextual factors on student teachers’ efficacy beliefs

This study investigated student teachers’ efficacy beliefs, collective teacher efficacy beliefs, and perceived cooperating teachers’ efficacy beliefs. These student teacher beliefs were examined with the focus on context, primarily the school setting (i.e., rural, suburban, and urban), to determine whether setting played a role in the development of the student teachers’ efficacy beliefs. The research participants included 102 student teachers. All three setting groups exhibited significant increases in teachers’ sense of efficacy following student teaching. Urban student teachers exhibited significantly lower perceived collective efficacy. Perceived cooperating teachers’ efficacy was predictive of and positively related to the student teachers’ post-TSES scores.     

Motivation to Learn Science: Differences Related to Gender,Class Type,and Ability

Abstract

Motivation differences of gender, science class type (biological vs. physical), and ability level of 242 high school students were investigated. High achievers and physical science students had higher scores than did low achievers and biological science students on academic goals, valuing science, and perceived ability. Boys had higher scores than did girls on perceived ability and stereotyped views of science. For only a subset of variables, these main effects were moderated by class type using achievement-level interaction. The class type main effect was moderated by gender in only one instance. Gender did not interact with achievement level for any variable. Instructional implications are discussed.

目的:探讨高强度间歇运动(HIIT)对长期住院男性精神分裂症患者的精神症状及康复疗效的影响。方法:将58名长期住院男性精神分裂症患者便利抽样分为对照组、研究组,研究组开展HIIT,共6个月。结果:两组患者的阳性和阴性症状评定量表(PANSS)、住院精神病人康复疗效评定量表(IPROS)、卡尔加里精神分裂症抑郁量表(CDSS)评分显著降低。患者CDSS 、IPROS评分在干预后3个月和6个月时,研究组优于对照组,差异有统计学意义(P<0.05)。结论:HIIT可以改善长期住院男性精神分裂症患者的精神症状,提     

Which inclusive teaching tasks represent the highest level of teacher efficacy in primary and secondary schools?

A hierarchy of inclusive teaching tasks by associated level of teacher efficacy is derived from a group of primary and secondary school teachers in Hong Kong using a Rasch rating scale model on 536 in-service teachers attending a professional development course. Findings show collaboration tasks represented the highest teacher efficacy in primary and secondary teachers. Managing behavior represented the lowest level of teacher efficacy but slightly more in primary than in secondary school. Hence, future training regarding inclusive practices should be specific to the school level, with a strong focus on collaborations between school, parents, and the community.

Promoting Academic Persistence Among Racial/Ethnic Minority and European American Freshman and Sophomore Undergraduates: Implications for College Counselors

Factors influencing persistence decisions among 346 racial/ethnic minority and 813 European American freshman and sophomore undergraduates were explored. Gender and racial/ethnic differences were found in centrality and public regard of racial/ethnic identity. Perceptions of the university environment and self‐beliefs predicted persistence decisions for everyone. Suggestions for college counselors working with students exhibiting risk factors for academic persistence are presented.     

心理权利对新时代大学生求职行为的影响研究

文章旨在探索心理权利对大学生求职行为的影响。首先假设了心理权利对大学生求职努力和职业生涯抱负的影响,提出心理权利有可能正向强化大学生的求职期望,却会削弱他们的求职努力;进一步提出朋辈求职进展有可能调节心理权利和求职努力的关系。采用问卷调研,回收有效问卷443份。结果表明:一是心理权利会正向影响大学生的求职期望和职业生涯抱负;二是朋辈求职进展能够显著调节心理权利和大学生求职努力之间的关系。
