ApoE基因多态性和运动与血脂异常的关系

载脂蛋白E有ApoE2、ApoE3和ApoE4三种主要的异构体,有ε2、ε3和ε4三种常见的等位基因,其基因编码可形成ApoE2/2、ApoE3/3、ApoE4／4三种纯合子表型和ApoE3／2、ApoE4/3、ApoE2／4三种杂合子表型．不同种族间ApoE等位基因的频率和基因型频率都不同．载脂蛋白E基因多态性是个体间血脂水平差异的常见遗传因素,与个体间血脂代谢和血脂异常的发生存在有一定的关联．此外,载脂蛋白E基因多态性可调节运动对血脂的影响作用,但其机制还有待于进一步的研究．     

Learning with immigrant children,families and communities: the imperative of early childhood teacher education

Abstract

This article reports on a longitudinal study spanning over 5 years, involving the design and implementation of an early childhood teacher education program model that engages a critical-ecological theoretical approach, a funds of knowledge perspective, and design-based methodology. This project aimed to promote equitable education for all children, and especially for young immigrant children encountering situations of oppression within the national and local educational contexts in Arizona. In this teacher education program, families, community members, researchers, pre-service teachers and teachers worked together to develop new modes of curricular activity, new spaces, new relationships, and new forms of movement among participants, as well as new circulations of literacy artefacts.

试论建国初期我国学校体育的创建

文章认为建国初期我国学校体育的创建,实际经历了两个阶段.第一阶段1949～1962年,主要是实现了由旧体育向新体育的根本性转变;第2阶段1953～1956年,主要是模仿前苏联模式而建构新中国的学校体育体系.从1956年国家颁布第一个全国性的各级各类学校体育教学大纲开始,标志着具有前苏联模式的我国学校体育体系形成,并从此影响了我国学校教育近50年的历史.

The development of student teachers’ professional identity

This study focuses on student teachers’ perceptions of their professional identity. The respondents are students enrolled in a three‐year course in secondary education teaching at bachelor level. Questionnaires were filled out by first‐year, second‐year and third‐year students from two colleges. The questionnaire included four scales: commitment to teaching, professional orientation, task orientation and self‐efficacy. In the first five months of the first‐year course, a shift in students’ task orientation was observed: students developed a more pupil‐centred view on teaching. Practical experience with classroom teaching again caused a shift: students focused less on the subject matter, on maintaining order in the classroom, on the long‐term educational qualification targets and self‐efficacy decreased. Students with work placement experience developed a more ‘realistic’ view of learning and teaching compared to students without this experience. A final important difference in professional identity is based on students’ gender: while male students tend to attach more importance to discipline in the classroom, their female counterparts focus more on student involvement.     

把握多元品德评价尺度 提升教师评价素养

作为学校德育评价机制的一部分,学生品德评价是学校德育评价的核心,全体中小学教师都肩负着育人的使命,肩负着品德评价的责任。确立评价尺度多元的理念,掌握多元品德评价尺度,提高教师的品德评价素养已经成为新时期教师专业发展的必然要求。教师要研读相关标准,明确基本依据,以合格性评价为基础;立足学校特色,彰显学校个性,把握多元校本化评价尺度;包容个体起点,尊重学生差异,掌握多元生本化评价尺度。
