Development and Implementation of an Inquiry-Based, Laboratory-Driven, General Chemistry Sequence

化学（12）在斯基德莫尔学院，发现化学（DC）教学方法被纳入荣誉普通化学（107H/207H）序列。CHEM 107H正在通过实施所有新的实验室经验进行修订，这些经验使用基于查询的协议并产生大型数据集。在模仿真实科学探究的方法中，实验室的结果构成了课堂教学的基础。此外，PI正在开发一门新颖的，基于实验室的法医化学课程（CHEM 207H）。本课程的实验练习将挑战学生对化学方法论的全面理解，并将在模拟法医调查中达到高潮。目前正在采用一项涉及定量和定性方法的全面、多管齐下的评估计划。正在收集实施DC之前关于学生态度、学习和参与的基线数据，以及形成性和总结性数据。成功的基准包括增加从CHEM 107H到CHEM 207H的学生人数；增加了从CHEM 207H升读理科课程的学生人数；提高理科专业代表性不足的学生的留校率和进步，改善学生对科学的态度；在学生学习的三项指标上也取得了更好的成绩。拟议工作的实施对那些在CHEM 107H/207H序列中注册的学生有重大影响。通过邀请大奥尔巴尼/首都地区所有两年制和四年制大学的化学教师以及六所当地高中的AP化学教师，一个关于DC实施和评估的研讨会将鼓励区域性的教学创新讨论。

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.
