Chemistry(12) This project is integrating inquiry-based experiences into two high-profile chemistry courses to promote student learning, engagement, and excitement toward science. The Analytical Chemistry laboratory is focusing on three primary goals: development of laboratory skills, enhancement of proficiency with analytical instrumentation, and engagement in the process of critical analysis. In the first half of the course, students are developing laboratory skills and instrumental proficiency by rotating through six different instruments performing quantitative analyses of unknowns. In the second half of the course, pairs of students are using these skills to design and perform a quantitative chemical analysis of a real-world sample. The students are responsible for directing each step in the analytical process: sample collection, sample preparation, data acquisition, data interpretation, conclusion formation, and information dissemination.Small groups of students in the General Chemistry II laboratory are engaging in mini-research projects focused on an issue of relevance - the fate of pharmaceuticals in natural waters. In the first half of the course students are carrying out experiments that prepare them for their research projects. Then in the second half of the course, each group is developing a hypothesis, creating and carrying out an experimental plan for hypothesis testing, evaluating their results, and presenting their conclusions. This project is adapting established models of inquiry-based laboratory instruction and implementing them into two popular courses to excite and educate the next generation of scientists. Assessment outcomes will be of interest to educators across the sciences, because stimulating student learning, interest, and excitement are objectives shared by all.

化学（12）该项目将基于探究的经验整合到两个备受瞩目的化学课程中，以促进学生的学习，参与和对科学的兴奋。 分析化学实验室专注于三个主要目标：实验室技能的发展，分析仪器的熟练程度的提高，并在关键分析过程中的参与。 在课程的前半部分，学生通过旋转六种不同的仪器来发展实验室技能和仪器熟练度，对未知物进行定量分析。 在课程的后半部分，成对的学生将使用这些技能来设计和执行真实世界样品的定量化学分析。 学生们负责指导分析过程中的每一个步骤：样品收集、样品制备、数据采集、数据解释、结论形成和信息传播。普通化学II实验室的学生小组正在从事小型研究项目，重点关注一个相关问题-天然沃茨中药物的命运。 在课程的前半部分，学生们正在进行实验，为他们的研究项目做准备。 然后在课程的后半部分，每个小组都在开发一个假设，创建和执行假设检验的实验计划，评估他们的结果，并提出他们的结论。 该项目正在调整以探究为基础的实验室教学的既定模式，并将其纳入两门受欢迎的课程，以激发和教育下一代科学家。 评估结果将引起各学科教育工作者的兴趣，因为激发学生的学习、兴趣和兴奋是所有人共同的目标。
