Mastery of core chemistry content is a degree requirement for several STEM majors. Gatekeeper courses, like general and physical chemistry, have a history of weeding out struggling students, and often underrepresented groups underperform. While gatekeeper courses ensure students are prepared for STEM degrees, it is essential they do not create undue obstacles or dampen interest in STEM. This article describes the implementation and evaluation of efforts to infuse polymer science into a two-semester sequence of general and physical chemistry courses. Survey and focus group data revealed positive feedback from students. Also, improved student mastery of polymer concepts and knowledge was demonstrated in pre- and postassessments. Ultimately, these initial efforts provided students with additional foundational skills and increased engagement with chemistry content.

通过在Gatekeeper化学课程中实施聚合物注入来增加化学含量的参与度

精通核心化学内容是几​​个STEM专业的学位要求。诸如一般化学和物理化学之类的关守课程，都有淘汰苦苦挣扎的学生的历史，而且往往代表性不足的群体表现不佳。看门人课程可确保学生为获得STEM学位做好准备，但必不可少的一点是，不要对STEM造成不必要的障碍或产生兴趣。本文介绍了将聚合物科学注入常规化学和物理化学课程两个学期序列的工作的实施和评估。调查和焦点小组的数据显示学生的积极反馈。此外，在评估前和评估后，学生对聚合物概念和知识的掌握程度得到了提高。最终，
