Enhancing Student Engagement in the Analytical Process and Scientific Inquiry in the Chemistry Curriculum at Concordia College

化学（12）本项目将探究性经验融入两门备受瞩目的化学课程中，以促进学生对科学的学习、参与和兴奋。分析化学实验室关注三个主要目标：发展实验室技能，提高分析仪器的熟练程度，参与关键分析过程。在课程的前半部分，学生通过轮换使用六种不同的仪器对未知事物进行定量分析，来培养实验技能和仪器熟练程度。在课程的后半部分，学生将使用这些技能设计并执行一个真实世界样本的定量化学分析。学生负责指导分析过程中的每一步：样品收集、样品制备、数据采集、数据解释、结论形成和信息发布。普通化学II实验室的学生小组正在从事一个小型研究项目，重点关注一个相关问题-药物在天然水中的命运。在课程的前半部分，学生将进行实验，为他们的研究项目做准备。然后在课程的后半部分，每个小组都要提出一个假设，创建并执行一个假设检验的实验计划，评估他们的结果，并提出他们的结论。该项目采用探究式实验教学模式，并将其应用于两门受欢迎的课程中，以激发和教育下一代科学家。评估结果将引起各学科教育者的兴趣，因为激发学生的学习、兴趣和兴奋是所有人的共同目标。

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.
