A Study of Highly Qualified Science Teachers' Career Trajectory in the Deep,Rural South: Examining a Link Between Deprofessionalization and Teacher Dissatisfaction

Science teacher retention, attrition, and migration continue to perplex educational scholars, political entities, as well as the general public. This study utilized an interpretive methodological design to generate assertions regarding career choice made by highly qualified science teachers in the deep, rural South through analysis of documents, interviews, focus groups, and observation. Generally considered “difficult to staff” because of location, socioeconomics, and demographics, Wilson County High School is an exemplar in science teacher retention and student achievement. Findings presented include how the science department at Wilson County improved student learning outcomes as well as the reasons why two of the highly qualified science teachers at this school were considering leaving the profession they love.     

美国《科学教师培养标准(2020年版)》述评*

美国《科学教师培养标准(2020年版)》针对《新一代科学教育标准》的推行而修订,立足于科学教育最新研究成果,尤其突出学科内容知识的重要性,补充对科学本质和科学文化的要求,强化对工程和技术、交叉概念、学科观念的理解,突出学习进阶规律在科学教师培养中的应用。此外,在学科教学法、学习环境、安全、对学生学习的影响等维度做出相应的改动。该标准启示我国:借鉴国际改革趋势出台中国特色的科学教师培养标准,但科学教师培养也要本土化;学科内容知识对科学教师专业发展非常重要;科学教师的培养应立足于学习进阶的规律;职前科学教师培养需要注重学习环境建设。     

职前与在职化学教师对教学能力认知差异的实证研究*

采用定量的方法对112位化学师范生和83位中学化学教师进行问卷调查,了解职前、在职教师对教学能力要素重要性认识的情况,问卷涉及本体要素、工具要素、条件要素、实践要素、情意要素和发展要素等6大维度。基于Rasch测量模型,利用ConQuest,Winstep,SPSS22.0软件对数据进行统计分析。研究发现:(1)问卷具有良好的信效度;(2)师范生、在职教师均把情意要素作为教学能力的首要成分,其次依次是本体要素、发展要素、实践要素,工具要素与条件要素排在其他要素之后;(3)工具要素重要性赞同度师范生显著高于在职教师,其余维度差异不显著,不同性别各维度重要性赞同度也无显著性差异;(4)由ConQuest多维分析所建立的项目被试图可以直观展示不同维度上各教学能力的重要程度。     

地方高校化学师范生对教师职业认同现状及影响因素调查研究

采用问卷和访谈的方式对化学师范生对教师职业认同情况进行了调查。结果表明：化学师范生对教师职业认同总体水平较高;教师职业认同水平在性别上差异不显著;教师职业认同水平在年级上差异显著,大一师范生的认同水平较高。根据调查结果,分析了化学师范生对教师职业认同的影响因素,并就提升化学师范生对教师职业认同提出了建议。     

高师生实验探究洋葱中挥发性化学物质

新手化学教师NOS-PCK的调查研究*

使用内容分析法,以广东省的30名新手化学教师为样本,测查了他们在教学设计中体现的NOS-PCK组分情况。结果表明:新手化学教师的NOS-PCK大部分能涉及到2~3种组分。具体而言,KoS组分出现的频次最高,KoA组分次之,而KoC组分与KoL组分出现的频次较低。据此对我国化学教师教育及其研究提出相关建议。

Secondary-school teachers’ noticing of aspects of mathematics teaching talk in the context of one-day workshops

In a research project with one-day teacher education workshops for secondary-school mathematics teachers, our study explores the potential of tool-supported discussions in helping them to notice important and critical aspects of mathematics teaching talk. Mathematical practices of naming and explaining in teaching talk, students’ content learning challenges, and noticing processes of identifying, interpreting and deciding are the components of our framework and the tools that guided the design and implementation of three workshops on linear equations, fractions and plane isometries. The data was collected during the discussions with the seven teachers and the teacher educator throughout these workshops. The coding of the discussions allowed us to see discourse moves that reveal the teachers’ noticing of: (i) challenges in the identification of mathematical naming, (ii) mathematical explaining that voices the students’ learning, (iii) classroom practice in relation to mathematical naming and explaining.
