中文摘要
化学(12)最近化学教育的注意力集中在“以问题为基础的”学习(PBL)策略的需要上,特别是在实验室。行业和政府实验室化学家对化学本科生的培养表达了一种担忧,即学生对化学分析只有一个基于技术的观点,而不是将其视为一个基于解决问题的综合过程。学生教育中的综合概念“分析过程”已经失传。要弥补这方面的不足,我们必须培养学生的批判性思维和解决问题的能力。尽管通过实验室PBL经验来实现这一目标是可取的,但许多机构,特别是小型学院,缺乏有效解决分析化学实验室实际问题所需的仪器。最近新电子技术的爆炸性发展,作为实验室课程中央实践部分的补充,提供了通过交互式计算机体验提高学生解决问题的技能的机会。该项目继续开发MCPweb,这是一个基于Web的交互式材料表征项目(MCP)。此虚拟练习基于目前亚利桑那大学分析课程中提供的MCP的实验室版本,在该课程中,学生对商业产品、设备或配方进行全面分析。这个项目的目标是完成电子计算器的MCPweb原型,以证明这一概念的可行性。这项活动主要面向全国化学专业本科生。此外,这项活动也与在分析化学教育中加强使用技术的需要很好地匹配。
英文摘要
Chemistry (12) Recent attention in chemical education has focused on the need for "problem-based" learning (PBL) strategies, particularly in the laboratory. One concern expressed by industry and government laboratory chemists about the training of chemistry undergraduates is that students emerge with only a technique-based perspective on chemical analysis instead of viewing it as an integrated process based on problem-solving. Education of students in the integrated concept of the "analytical process" has been lost. The remedy to this curricular deficiency requires the development of critical thinking and problem-solving skills in our students. Although it is desirable to achieve this goal through laboratory PBL experiences, many institutions, particularly small colleges, lack the instrumentation necessary for effective solution of real-world problems in their analytical chemistry laboratories. The recent explosion in new electronic technology affords, as a supplement to the central hands-on component of the laboratory curriculum, the opportunity to enhance the problem-solving skills of students through interactive computer-based experiences. This project continues the development of MCPweb, an interactive Web-based Materials Characterization Project (MCP). This virtual activity is based on a laboratory version of the MCP currently offered in the analytical curriculum at the University of Arizona in which students undertake a comprehensive analysis of a commercial product, device, or formulation. The goal of this project is to complete the prototype MCPweb for the electronic calculator to demonstrate the feasibility of this concept. This activity is primarily targeted towards undergraduate chemistry majors nationwide. In addition, this activity is also well-matched to the need for enhanced use of technology in analytical chemistry education.
