Development of Technology Based Assessments in Chemistry

化学（12）在过去的十年里，科学教育的一个主要重点是发展课程，以丰富本科生对知识的理解和欣赏，并提高继续学习所需的技能。然而，通常采用的评估技术并不一定评估国家标准中强调的学习类型。加州大学洛杉矶分校的互动多媒体练习项目一直在利用现代技术，使教育工作者有机会在现实环境中教授、观察和评估学生的表现。将IMMEX学习和评估技术整合到小学、中学和医学院课堂的10多年经验告诉我们，有一些方法可以克服真实学习和评估的风险，并使用这些方法来实现NRC和其他人所设想的目标。我们正在开发一套完整的IMMEX材料，用于两个学期的普通化学课程。该计划的主要合作伙伴是Learning Chameleon（IMMEX软件许可组织）、克莱姆森大学和堪萨斯大学。试点测试也正在进行哈钦森社区学院和克拉夫林学院，并与新的美国化学学会普通化学文本。该项目分为三个阶段：1。将现有材料（10个问题，300个案例）整合到两个不同的普通化学课程中。2.新问题的开发（a）解决第二学期化学内容，和（B）压缩问题空间并集中于一个特定概念或技能的实验类型的问题。这些问题被用作评估工具和诊断工具，以确定不同类型的问题解决者。3.根据对学生解决问题时实际采用的策略的分析，制定具体的干预措施，以帮助学生变得更加熟练。该项目的成果将是一套适合普通化学课程的IMMEX问题，一本详细介绍该计划的工作簿和一本教师手册。

Chemistry (12)A major emphasis in science education over the past decade has been the development of programs to enrich undergraduate understanding and appreciation of knowledge, and to improve the skills necessary for continued learning. However the assessment techniques typically employed do not necessarily assess the kinds of learning emphasized in national standards. The Interactive Multi-media Exercises (IMMEX) project at UCLA has been exploiting modern technology to allow educators the opportunity to teach, observe and assess student performances in realistic settings. More than 10 years of experience with integrating IMMEX learning and assessment technology into primary, secondary and medical school classrooms suggests to us that there are ways to overcome the perils of authentic learning and assessment, and to use these methods to achieve the goals envisioned by the NRC and others. We are building upon this proven assessment technique by developing a full suite of IMMEX materials for a two semester general chemistry course. The major partners in this plan are Learning Chameleon (the licensing organization for IMMEX software), Clemson University and the University of Kansas. Pilot testing also is being carried out at Hutchinson Community College and Claflin College, and in conjunction with the new American Chemical Society General Chemistry text. The project has three phases: 1. The integration of existing materials (10 problems, 300 cases) into two different general chemistry programs. 2. The development of new problems (a) to address second semester chemistry content, and (b) an experimental type of problem that compresses the problem space and concentrates on one particular concept or skill. These problems are being used both as an assessment tool and as a diagnostic tool to identify different types of problem solvers. 3. The development of specific interventions to help students become more proficient, based on the analysis of the strategies our students actually employ when solving problems. The outcomes of this project will be a suite of IMMEX problems suitable for general chemistry courses, a workbook detailing the program and an instructors manual.
