Collaborative Research: Multimedia Engineering Notebook Tools to Support Engineering Discourse in Urban Elementary School Classrooms

这个协作性、探索性、学习型项目的重点是提高小学生在工程设计过程中的规划和再设计活动中的反思决策能力。来自三所小学的五名教师研究人员为研究提供了课堂实验室。指定单元工程是基础，一个精心研究的课程，提供工程内容。在第一年，定性研究观察学生在开发设计时的话语。在此基础上，设计了一种带有提示的纸质工程笔记本，供二年级学生使用，同时开发了一种数字笔记本。在第三年，学生们使用电子笔记本来开发他们的设计和重新设计。该研究确定了有助于反思性话语的语言模式，并确定了纸质和电子版本的笔记本如何改善话语。咨询委员会提供建议和评估。会议记录中描述了这些笔记，并在网上提供。这项工作综合了关于在小学科学和工程教育中使用笔记本的已知情况，并研究了如何通过数字媒体改善笔记本的使用。

This collaborative, exploratory, learning strand project focuses on improving reflective decision-making among elementary school students during the planning and re-design activities of the engineering design process. Five teacher researchers in three elementary schools provide the classroom laboratories for the study. Specified units from Engineering is Elementary, a well-studied curriculum, provide the engineering content. In year one, the qualitative research observes student discourse as students develop designs. Based on the results, a paper engineering note book with prompts is designed for use in year two while a digital notebook is developed. In year three, the students use the digital notebook to develop their designs and redesigns. The research identifies patterns of language that contribute to the reflective discourse and determines how the paper and electronic versions of the notebook improve the discourse. An advisory committee provides advice and evaluation. The notebooks are described in conference proceedings and made available online. This work synthesizes what is known about the use of the notebooks in science and engineering education at the elementary school and investigates how to improve their use through digital media.
