Conducting a Delphi Study as the First Step in Developing a Concept Inventory for Engineering Design Graphics

(59)工程及(R)研究/评估该项目正在开发关于工程图形学基本概念的协议(以及测试方法)。其目标是开始开发经过验证和测试的概念清单的进程。第一步，也是这个项目的主要目标，是一项德尔福研究，以确定工程制图中的基本概念。结果将随后用于开发工程图学的概念清单。工程制图通常是工程学中招生人数最多的课程之一。今天的大部分工程图学教育倾向于关注“当今的工具”，而不是基本的概念。学生在高中、社区大学和四年制院校学习工程制图。工科学生、工科学生和技师学生都选修工程图学课程。几乎没有人尝试在教育领域的不同级别的这些课程之间建立联系。工程图学的概念清单将：(1)使高中教师能够确保他们所涵盖的主题能够很好地适用于高等教育环境；(2)确保两年制和四年制院校之间有更大程度的衔接；(3)使各级图学课程改革。STEM领域的许多基础课程的概念清单已经开发。在过去的几十年里，在为工程课程开发概念清单方面做了大量的工作。概念清单被视为推动课程改革的一种手段，因为它们允许教师在设计课程时将重点放在基础知识上，并为他们提供了一种评估学生对这些基本概念理解程度的有效手段。

(59) Engineering and (R) Research/ Assessment. This project is developing agreement about (and a means for testing) the fundamental concepts in engineering graphics. Its goal is to begin the process of developing a validated and tested concept inventory. The first step, the primary objective of this project, is a Delphi Study to identify the fundamental concepts in engineering graphics. The results will subsequently be used to develop a concept inventory for engineering graphics. Engineering graphics is often one of the largest enrollment courses within engineering. Much of engineering graphics education today tends to focus on the "tool of the day" rather than the fundamental concepts. Students are enrolled in engineering graphics within high schools, community colleges, and four-year institutions. Engineering students, technology students, and technician students all take engineering graphics courses. There has been little attempt to articulate between these courses across the various levels in the educational spectrum. A concept inventory for engineering graphics would: (1) enable high school teachers to ensure that the topics they cover translate well to higher education settings; (2) ensure a greater degree of articulation between 2-year and 4-year institutions; and (3) enable graphics curriculum reform at all levels.Concept Inventories have been developed for many fundamental courses in the STEM fields. In the past few decades, much work has been done in developing concept inventories for engineering courses. Concept inventories are viewed as a means for spurring curriculum reform because they allow faculty to design their courses with a focus on the fundamentals and they provide them with a validated means of assessing student understanding of these basic concepts.
