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

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（107 H/207 H）序列。CHEM 107 H正在通过实施所有新的实验室经验进行修订，这些实验室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，PI正在开发一种新的，以实验室为基础的法医化学课程（CHEM 207 H）。 本课程的实验室练习是对学生的挑战，以培养对化学方法的全面理解，并将在模拟法医调查中达到高潮。 目前正在采用一项全面、多管齐下的评估计划，包括定量和定性方法。 正在收集关于学生态度、学习和参与的基线数据，以及形成性和总结性数据。 成功的基准包括从化学107 H进展到化学207 H的学生人数增加;从化学207 H进展到进一步的科学课程的学生人数增加;改善学生的保留和进步，通常在科学中代表性不足的人群，改善学生对科学的态度;和学生学习的三个措施更好的结果。 拟议工作的实施对那些在CHEM 107 H/207 H序列中注册的学生产生了重大影响。 关于DC的实施和评估的研讨会将通过邀请来自大奥尔巴尼/首都区所有两年制和四年制机构的化学教师以及来自六所当地高中的AP化学教师来鼓励对教学创新的区域范围的讨论。

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.
