The purpose of this project is the collection and publication of at least twelve reviews covering the descriptive inorganic chemistry of the most important elements and their simple compounds, both in the pure state and in aqueous solution. The reviews, for the most part, will be published in the Journal of Chemical Education. They will later be collected in reprint volumes for teachers. The reviews are being modeled on the curriculum developed by W. C. Bray and W. M. Latimer, "A Course in General Chemistry". The general characteristics of the reviews include: coverage of the chemistry of everyday materials rather than esoteric compounds; inclusion of laboratory exercises and demonstrations graded as to suggested usage level; description of safety and waste disposal methods; and de-emphasis of heavily theoretical models in comparison with qualitative models. In conjunction with the project, a Policy Group, consisting of chemical educators from both higher education institutions and secondary schools is being formed. A second group, the Reactivity Network, will consist of highly qualified secondary school chemistry teachers who will serve on writing teams and give presentations about the review program at professional meetings. This project will address a serious shortcoming in precollege chemical education by providing materials focused on descriptive chemistry, an area largely ignored in current texts. Secondly, it will help to modify the present approach to laboratory work in that the laboratory activities will become the central feature of the materials, and will involve the solution of problems rather than the performance of illustrative experiments.

该项目的目的是收集和出版至少12篇综述，涵盖最重要元素及其简单化合物的描述性无机化学，包括纯态和水溶液。这些评论大部分将发表在《化学教育杂志》上。稍后将收集成重印卷供教师使用。这些评论是以W. C. Bray和W. M. Latimer开发的课程“普通化学课程”为蓝本的。评论的一般特点包括：涵盖日常材料的化学，而不是深奥的化合物；包括按建议使用水平分级的实验室练习和演示；对安全和废物处理方法的说明；与定性模型相比，不再强调理论模型。为了配合这个项目，正在成立一个政策小组，由高等教育机构和中学的化学教育工作者组成。第二组是反应网络，将由高素质的中学化学教师组成，他们将组成写作小组，并在专业会议上就审查程序发表演讲。这个项目将通过提供着重于描述化学的材料来解决大学前化学教育中的一个严重缺陷，这一领域在当前的文本中很大程度上被忽视了。其次，它将有助于修改目前的实验室工作方法，因为实验室活动将成为材料的中心特征，并将涉及问题的解决而不是说明性实验的表现。
