An Interactive Web-Based Materials Characterization Project for Undergraduate Education in Analytical Chemistry

化学（12）最近化学教育的注意力集中在需要“基于问题的”学习（PBL）策略，特别是在实验室。 工业和政府实验室化学家对化学本科生培训的一个担忧是，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。 教育学生的综合概念的“分析过程”已经丢失。 要弥补这一课程缺陷，就需要培养学生的批判性思维和解决问题的能力。 虽然它是可取的，以实现这一目标，通过实验室PBL的经验，许多机构，特别是小型院校，缺乏必要的仪器，有效解决现实世界中的问题，在他们的分析化学实验室。 近年来，电子科技的发展，为学生提供了一个机会，透过互动式的电脑体验，加强学生解决问题的能力，以补充实验室课程的核心实践部分。 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）。该虚拟活动基于亚利桑那大学分析课程中目前提供的MCP实验室版本，其中学生对商业产品，设备或配方进行全面分析。本项目的目标是完成电子计算器的原型MCPweb，以证明这一概念的可行性。该活动主要针对全国化学专业本科生。此外，这一活动也很好地配合了在分析化学教育中加强利用技术的需要。

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.
