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.

化学（12）本项目将高阶发现实验（DEXS）的概念融入化学课程，加强化学概念学习。这涉及修改现有的临时实验，从文献中改编新的发现实验，并创建虚拟计算机模拟发现实验。该项目涉及八个普通化学，介绍化学，有机化学实验室课程和荣誉课程一般和有机化学。该模式还扩展到高级化学课程，非科学专业实验室课程，以及计划进入学院或大学的少数民族学生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，增强了概念理解和批判性推理能力，提高了学生对实验室的兴趣和参与度。实验室改造导致额外的团队建设和教师之间的合作，他们构建了程序，并指导伴随实验室部分的讲座课程。这些材料可通过光盘、网页和出版物获得。
