Purpose

This study aims to explore how the theories of professional capital and decisional capital can be extended to introduce “professional mathematics capital” and “decisional mathematics capital”.

Design/methodology/approach

Professional development (PD) efforts in one school district in elementary mathematics education are described to illustrate these extensions and to contemplate ways to enhance teacher learning of mathematics pedagogy.

Findings

Both theoretical extensions provided useful frameworks for conceptualizing mathematics PD. Preliminary evidence suggests that participants demonstrated the emergence of professional and decisional mathematics capital.

Research limitations/implications

While there were observed and reported changes to teacher practice, further research is needed to explore the implications of these theoretical extensions on student learning.

Originality/value

This study serves to enhance the literature related to PD and teachers' mathematical content knowledge. The theoretical extensions of professional and decisional mathematics capital are a novel and promising concept that allows for a unique approach to be laid out for those designing PD in mathematics.

专业和决策数学资本的系统方法

目的

本研究旨在探讨如何将专业资本和决策资本的理论扩展为引入“专业数学资本”和“决策数学资本”。

设计/方法/方法

描述了一个学区在基础数学教育中的专业发展（PD）工作，以说明这些扩展并探讨增强教师对数学教学法的学习的方法。

发现

两种理论的扩展都为将数学PD概念化提供了有用的框架。初步证据表明，参与者证明了专业和决策性数学资本的出现。

研究局限/意义

尽管已经观察到并报告了教师实践的变化，但仍需要进一步研究以探索这些理论扩展对学生学习的影响。

创意/价值

这项研究有助于增进与体育锻炼有关的文献和教师的数学内容知识。专业和决策数学资本的理论扩展是一个新颖而有前途的概念，可以为那些设计PD的人设计一种独特的方法。
