The Developmental Mathematics Collection: Extending the NSDL with content and knowledge syntheses on exemplary practices for Developmental Mathematics

数学（21）对数学发展材料的需求越来越大。 加州社区学院的一个教师团队一直在从事发展数学课程的重新设计，他们收集并创建了实际操作活动，这些活动具有有形的操作材料，供学生在讲座和实验室环境中使用。 这些资源正在提供和分类的方式适合谁教发展数学课程的教师使用。 发展数学收藏及其相关网站提供了一个机会，以汇集这些资源，使他们更广泛地提供。 在全州范围内的互补努力的基础上，该项目将建立一个发展数学教师社区，他们与其他教师在线共享资源，在他们的发展形成阶段提供反馈，并通过增值注释和审查这些数字资源对发展数学特定课程水平的适用性来交换知识。 该网站将托管一个元数据记录，该记录将收集的每个主要元素与以下信息进行分类：标题，URL，描述，资源创建者，教育水平和主题关键字。 集合中的资源可以通过公共课程标签（例如，前代数，初级代数，中级代数），在程序，课程，课程和活动水平的教学内容知识，并通过职业或个人兴趣的领域。

Mathematics (21)There is a growing need for developmental materials in mathematics. A team of California community college faculty who have been engaged in redesigning courses in Developmental Mathematics have collected and created hands-on activities with tangible manipulative materials for use by students in lecture and lab settings. These resources are being made available and categorized in ways suited for use by instructors who teach developmental mathematics courses. The Developmental Mathematics Collection and its associated website provide an opportunity to aggregate such resources and make them more widely available. Building on complementary state-wide efforts, the project will build a community of Developmental Mathematics faculty who share resources online with other instructors, for feedback in their formative stage of development and for exchanging knowledge via value-added annotation and review of the suitability of these digital resources for specific course levels in Developmental Mathematics. The site will host a metadata record that catalogs each major element of the collection with the following information: title, URL, description, resource creator, education level and subject keywords. The resources in the collection are searchable by common course labels (e.g., Pre-algebra, Elementary Algebra, Intermediate Algebra), by pedagogical content knowledge at the program, curriculum, course and activity level, and by areas of vocational or personal interest.
