项目摘要

This project will improve the assessment of undergraduate students' hands-on chemistry laboratory skills through an innovative method known as digital badging. A digital badge allows faculty to create tasks (challenges) that students complete by uploading media or links that can be assessed by an instructor. Students will demonstrate how they meet learning objectives through authentic performances such as demonstrating and describing how to correctly use a pipet to measure a specific volume of liquid. This project will explore the relationship between student motivation and digital badging using expectancy-value theory, a specific theory of motivation. This work represents frontier research that will bring innovative assessment practices to the undergraduate science, technology, engineering, and mathematics community and will build evidence about effective pedagogical practices.The relationship between student motivation and digital badging, a novel and innovative approach to improve and assess student's hands-on laboratory skills, will be explored using expectancy-value theory, which focuses on a student's expectancies in terms of knowledge, confidence, experience, and value to characterize the ways in which students interact with digital badges. The digital badge will allow faculty to create tasks (challenges) that encourage students to demonstrate how they meet learning objectives through authentic performances. Students will complete retrospective pre and post surveys pertaining to their knowledge, confidence, and experience as part of the badging process. These data will allow determinations to be made about the expectancy perspectives of the students. Value instruments will be developed and analyzed, which will allow the characterization of the ways in which students find badging to be useful, interesting, and attainable, as well as how much it costs in terms of time or stress. By combining the findings from these surveys, the relationship between motivation and badging will be elucidated.

该项目将通过一种被称为数字标记的创新方法来提高对本科生化学实验室动手能力的评估。数字徽章允许教师创建任务（挑战），学生通过上传可以由教师评估的媒体或链接完成。学生将通过真实的表演来展示他们如何达到学习目标，例如演示和描述如何正确使用移液管来测量特定体积的液体。这个项目将探讨学生的动机和数字徽章使用期望价值理论，一个具体的动机理论之间的关系。这项工作代表了前沿研究，将为本科科学，技术，工程和数学社区带来创新的评估实践，并将建立有效的教学实践的证据。学生动机和数字徽章之间的关系，一种新颖的创新方法，以提高和评估学生的动手实验室技能，将使用期望值理论，它侧重于学生在知识，信心，经验和价值方面的期望，以描述学生与数字徽章互动的方式。数字徽章将允许教师创建任务（挑战），鼓励学生展示他们如何通过真实的表现达到学习目标。学生将完成有关他们的知识，信心和经验作为徽章过程的一部分回顾性前和后调查。这些数据将允许确定学生的期望前景。价值工具将被开发和分析，这将允许学生发现徽章是有用的，有趣的，可实现的方式的特征，以及它在时间或压力方面的成本。通过结合这些调查的结果，动机和徽章之间的关系将得到阐明。
