Discovery Experiments as a Vehicle for Enhanced Learning

本项目将高阶发现实验（DEXS）的概念引入化学课程，加强化学的概念性学习。这包括修改现有的说明性实验，从文献中改编新的发现实验，以及创建虚拟计算机模拟的发现实验。该项目包括八门普通化学、化学入门、有机化学实验课程，以及普通化学和有机化学荣誉课程。该模式还扩展到高级化学课程、非科学专业的实验课程，以及为计划进入学院或大学的少数民族学生提供的大学预科发展计划。将基于发现的实验与基于探究/问题的实验（串联实验）结合起来，可以增强概念理解和批判性推理能力，提高学生对实验室的兴趣和参与度。实验室的改造导致了额外的团队建设和教师之间的合作，他们构建了项目，并指导了伴随实验室部分的讲座课程。材料可在CD、网页和出版物中获得。

Chemistry (12)The project implements the concept of higher-order discovery experiments (DEXS) into the chemistry curriculum, enhancing conceptual learning of chemistry. This involves modification of existing expository experiments, adaptation of new discovery experiments from the literature, and the creation of virtual computer-simulated discovery experiments. The project involves eight general chemistry, introductory chemistry, and organic chemistry laboratory courses and honors courses in general and organic chemistry. The model is also extended to upper-level chemistry courses , non-science major laboratory courses, and the Pre-Collegiate Development program for minority students who are planning to attend a college or university. Coupling discovery-based experiments with inquiry/problem-based experiments (tandem experiments) enhances conceptual understanding and critical reasoning skills and increases student interest and involvement in the laboratory. The laboratory transformation leads to additional team building and cooperation among the faculty who construct the program and who instruct the lecture courses that accompany the laboratory sections. Materials are available on CD, web pages and in publications.
