Chemistry (12) The Discovery Chemistry (DC) pedagogical approach is being incorporated into the Honors General Chemistry (107H/207H) sequence at Skidmore College. CHEM 107H is being revised by implementing all new laboratory experiences that use inquiry-based protocols and result in large data sets. In a method that mimics authentic scientific inquiry, the laboratory results form the basis for classroom instruction. Additionally, the PI is developing a novel, laboratory-based course in forensic chemistry (CHEM 207H). Laboratory exercises in this course are challenging students to develop a holistic understanding of chemical methodology and will culminate in a simulated forensic investigation. A thorough, multi-pronged assessment plan involving both quantitative and qualitative methods is being employed. Baseline data on student attitudes, learning, and engagement before the implementation of DC as well as both formative and summative data are being collected. Benchmarks for success include increased numbers of students progressing from CHEM 107H to CHEM 207H; increased numbers of students progressing from CHEM 207H to further science courses; improved retention and progression of students from populations typically under-represented in the sciences, improved student attitudes about science; and better results on three measures of student learning. The implementation of the proposed work is having significant impacts for students beyond those enrolled in the CHEM 107H/207H sequence. A workshop on the implementation and assessment of DC will encourage region-wide discussions of pedagogical innovation by inviting chemistry faculty from all of the two-year and four-year institutions in the greater Albany/Capital District as well as AP Chemistry teachers from six local high schools.

化学(12)发现化学(DC)教学方法正在被纳入斯基德莫尔学院的荣誉普通化学(107H/207H)序列。正在通过实施所有新的实验室经验对化学107H进行修订，这些经验使用基于查询的协议并产生大型数据集。在一种模仿真实科学探究的方法中，实验室结果构成了课堂教学的基础。此外，国际法医学会正在开发一门以实验室为基础的新型法医化学课程(CHEM 207H)。本课程的实验练习将挑战学生对化学方法论的整体理解，并最终完成模拟的法医调查。目前正在采用一项全面、多管齐下的评估计划，包括定量和定性两种方法。在DC实施之前，正在收集关于学生态度、学习和参与度的基线数据，以及形成性和终结性数据。成功的基准包括：从CHEM 107H升至CHEM 207H的学生人数增加；从CHEM 207H升入进一步科学课程的学生人数增加；来自通常在科学方面代表性较低的人群的学生的保留率和进步率得到改善；学生对科学的态度得到改善；以及在学生学习的三项指标上取得更好的成绩。拟议工作的实施对注册CHEM 107H/207H序列的学生以外的学生产生了重大影响。关于DC的实施和评估的讲习班将通过邀请来自大奥尔巴尼/首都地区所有两年制和四年制机构的化学教师以及来自当地六所高中的AP化学教师来鼓励区域范围内关于教学创新的讨论。
