Collaborative Chemistry Laboratory Model (CCLM): Integrating Microcomputer-Based Laboratory with Interactive Multimedia Computer Simulations

这个项目是路易斯安那州的两所大学，巴吞鲁日的南方大学和查尔斯湖的麦克尼斯州立大学的共同努力。我们打算整合我们的资源，并开发一个协作化学实验室模式（CCLM），为本科化学，可以解决一些共同的问题。具体来说，学生在化学看门人课程中的表现不佳可能是由于探究技能（方法和推理）和对化学主题的概念理解不佳。这些问题反过来可能会对未来科学课程的进展产生不利影响。该模型基于建构主义学习理论与三种技术互动模式的整合，旨在增强对现象及其表征的体验。基于微型计算机的实验室（MBL），即美国国家科学基金会资助的LabWorks，允许学生设计实验，同时观察现象及其表示，并对其数据进行图形分析。互动多媒体计算机模拟（IMCS）是Riverdeep的化学探索者计算机建模和模拟，它扩大了学生的决策机会，并允许在颗粒水平上进行可视化。我们正在调整和整合MBL和IMCS系统的使用，以便学生在将MBL的改进方法与IMCS的概念丰富的微观世界结合起来时，可以模拟化学家的心理世界。在线合作/协作学习方法为学生提供了在两所大学之间分享经验和想法的机会。CCLM在大一化学实验课程中进行测试，随后将在高级课程中实施。该项目涉及分布在两所大学的800名STEM学生。教师发展研讨会被用来在由12所大学组成的LS-LAMP网络中分享研究成果。其他传播方法包括网络出版物和专业会议。

Chemistry (12)This project is a joint effort between two Louisiana Universities, Southern University in Baton Rouge and McNeese State University in Lake Charles. We intend to integrate our resources and develop a Collaborative Chemistry Laboratory Model (CCLM) for undergraduate chemistry that can address some common problems. Specifically, poor student performance in the chemistry gatekeeper courses may be due to poor inquiry skills (methodology and reasoning) and poor conceptual understanding of chemistry topics. These problems, in turn, may adversely influence progress in future science courses. The model is based upon the integration of constructivist learning theory with three interactive modes of technology that are designed to enhance experiences with a phenomenon and its representations. Microcomputer Based Laboratory (MBL), i.e., the NSF-funded LabWorks, allows student design of experiments, simultaneous observation of a phenomenon and its representations, and graphical analysis of its data. Interactive Multimedia Computer Simulations (IMCS), the Chemistry Explorer computer modeling and simulation from Riverdeep, expands student decision-making opportunities and allows visualization at the particulate level. We are adapting and integrating the use of the MBL and IMCS systems so that students can emulate the mental world of chemists when they couple the enhanced methodology of MBL with the conceptually rich microworld of IMCS. Online cooperative/collaborative learning methods are providing opportunities for students to share their experiences and ideas between the two universities. The CCLM is being tested in freshman chemistry laboratory courses and later will be implemented in advanced courses. The project involves 800 STEM students distributed within the two universities. Faculty development workshops are being used to share findings throughout the LS-LAMP network of 12 universities. Other methods of dissemination include web publications and professional conferences.
