论课程改革中的初高中化学衔接教学

实施中学化学课程改革,要坚持“为了每一位学生的发展”的基本理念,从知识体系、教学方法、学习策略和情感态度4个方面搞好初、高中化学衔接教学。     

高中化学新课程的校本化实施

高中化学新课程的校本化实施是指在遵照高中化学课程标准前提下,学校根据自身性质、特点和条件,将国家层面上规划的高中化学课程转变为适合本校学生学习需要的实践过程。高中化学新课程的校本化实施的外部条件有:国家要完善高中化学课程标准的修订;地方政府和师范院校要加大对高中化学新课程校本化实施的扶持。其内部运作可以从教学目标的校本化、教学内容的校本化、教学方式的校本化、教学评价的校本化等方面入手。

Guiding Teachers in the Use of a Standards‐Based Mathematics Curriculum: Teacher Perceptions and Subsequent Instructional Practices After an Intensive Professional Development Program

Reforms in mathematics education call for K‐12 teachers to employ standards‐based pedagogies, which embody the National Council for Teachers of Mathematics' principles and standards. In order to effectively support teachers' implementation of standards‐based curricula, professional development must be provided that meets teachers' needs. The professional development program in this study focused on the implementation of a standards‐based mathematics curriculum entitled Investigations in Number, Data, and Space (Investigations). This study uses Guskey's framework as a guide to examining teachers' perceptions of the impact of the professional development that they received; their perceptions of mathematics teaching and learning; and how elements of the professional development translated into practice. Twenty‐two participants were randomly selected from the 53 professional development participants to be interviewed and observed during their mathematics teaching. Using a constant comparison method, the data sources in this study highlighted themes surrounding teachers' experiences with professional development and the implementation of the curricula. The analysis of the data sources in this study highlighted themes surrounding teachers' experiences with professional development: teachers as learners, teachers as self‐evaluators, shifting paradigms, enactment of professional development content into practice, and the influence of the state standardized mathematics test. The results of this study have several implications for future professional development and also highlight some of the more general issues that teachers face when attempting to enact new knowledge and skills into their practice.     

Shifts of mathematical thinking in adolescence

This theoretical paper relates key features of the mathematics adolescents are expected to learn in school to other aspects of adolescent development. Difficulties in mathematical learning at that age include changes in perspective and in the actions that are mathematically productive. Commonly-recommended methods of trying to engage adolescents in mathematics do not necessarily enable students to shift to new perceptions and new ways of constructing mathematical understandings, yet the shifts students need to make are in accord with other aspects of adolescent development.
