High school students’ understanding of the function concept

This paper is a study of part of the Algebra Project's program for underrepresented high school students from the lowest quartile of academic achievement, social and economic status. The study focuses on students’ learning the concept of function. The curriculum and pedagogy are part of an innovative, experimental approach designed and implemented by the Algebra Project. The instructional treatment took place over 7 weeks during the Junior Year of 15 students from our target population. Immediately after instruction, a written instrument was administered followed, several weeks later, by in-depth interviews. The results are that many of our participants achieved a level of knowledge and understanding of functions on a par with beginning college students, including preservice teachers, as reported in the literature. Many conceptual difficulties that have been reported in the research literature were not as prevalent for our participants and some of them were capable of solving difficult problems involving composition of functions. We conclude that, with appropriate pedagogy, it is possible for students in the Algebra Project's target population to learn substantial and non-trivial mathematics at the high school level, and that the Algebra Project approach is one example of such a pedagogy.

Laying groundwork for an understanding of academic integrity in mathematics tasks

ABSTRACT

To date, the way that academic misconduct is manifested in undergraduate mathematics coursework has been unexamined in the literature, with the consequence that policy and preventive education can fail to address it appropriately. This paper describes the particular features of the responses expected in mathematical tasks and provides concrete examples of what lapses of integrity look like in this context. The intent is to lay groundwork for discussion and a response to this issue from within our discipline.     

化学专业学术型硕士研究生培养与本科科研训练有效衔接的探究

阐述了高水平学术型硕士研究生培养与本科科研体验衔接的基本情况,以化学专业为例,就学术型硕士培养与本科创新性科研实践的衔接模式进行了详细的剖析,指出2者的衔接有助于高层次、高科研水平与高创新能力的硕士研究生培养。     

化学类硕士研究生学业拖延影响因素的质性研究

学业拖延是当前化学类硕士研究生在科研活动中普遍存在的问题,成为阻碍学业进步的重要因素。研究选取16名化学类硕士研究生作为访谈对象,对访谈资料进行编码,通过分析发现,化学类硕士研究生学业拖延行为源自个体压力与动力的交互、个性与环境的对抗作用。基于此,研究构建了关于化学类硕士研究生学业拖延影响因素的模型,并对改善学业拖延行为提出了对策建议。     

新中国成立以来我国中学化学教科书发展中的问题审视

中华人民共和国成立以来,中学化学教科书的发展可以划分为5个阶段。化学教科书发展中的主要问题有：社会政治、意识形态与化学教科书发展关系的问题;化学教科书中理论联系实际的问题;用先进化学知识充实化学教科书内容的问题;化学教科书中元素化合物和基础理论的编排关系问题;化学教科书中学科知识结构与学生认识结构的匹配问题;学习国外教科书编写的问题等。审视其发展中的问题,揭示其历史发展规律,可以为教科书的建设提供借鉴和启示。

高二学生认知结构、学科核心素养及学习困难的测量——以“卤代烃”为例

基于FLOWMAP测查高二学生"卤代烃"认知结构,并采用学科核心素养探究学生"卤代烃"学习困难。研究表明,学优生认知结构的优势体现在较高的认知"整合度"和准确率,学困生的劣势体现在较低的信息检索效率,学优生更善于运用描述及情境推理等信息处理策略建构知识。学生达到不同素养水平的学业要求差异较大。学习困难主要有不知道卤代烃的分类及物理性质,不明白或混淆发生取代反应与消去反应的特征、条件等,不知道卤代烃的用途。
