Sketched-Truss Recognition Tutoring System

草图-桁架识别辅导系统通过主动学习和即时学生反馈研究改善学生学习(91)该项目旨在评估和改进桁架草图识别辅导系统，通过提供智能和即时反馈来增强工程学习。通过对学生学习的研究和基于研究结果对软件的修改，这项工作为未来开发更广泛的工程课程的辅导系统提供了跳板，包括但不限于热科学和一系列其他以力学为基础的课程。该软件在提供指导的同时，积极地让学生参与进来，并在学生理解的概念和更深层次的学习之间建立了认知框架。大多数教授都意识到开放式问题对于深化学习和提高创新技能的重要性。智力优势：STRAT(草图桁架识别和分析工具)有助于将开放式设计问题合并到大型传统课堂中。Strat软件的设计目的是提供一种更有效的方法来教授工程师基本的力学概念，从而使学习时间更有成效，并在课程中增加额外的材料。用户可以自然地绘制图表，因此与工具箱或其他基于CAD的程序不同，该工具没有陡峭的学习曲线。此外，需要的硬件非常少；一台标准的计算机和鼠标就足够了。该项目有两个目标。第一个目标是通过定量和定性的方法来衡量strat软件对学生学习的影响。该项目的第二个目标是根据实验数据、从学生和教授那里收集的客户需求以及用户反馈来改进和改进Strat软件。为了增加外部效度和实用性，START正在课堂环境中进行测试。广泛的影响：START软件有可能深刻地提高学生的学习和教学过程的效率。战略工具可在各种高等教育机构使用，从侧重教学的学校的小教室到拥有非常大教室的注重公共研究的大学。可视化辅助工具在土木工程和机械工程中很常见，但主动绘制草图和反馈会带来额外的好处。提供即时反馈可以消除强化学习者产生的不准确假设的可能性，从而提高学习效果。草图工具还鼓励用户主动处理信息，而不是被动地查看视觉表示。自由素描的任务鼓励并要求学习者积极建构他们的知识，从而获得更高水平的理解和更长期的学习。这种学习方法也特别适用于科学，因为它鼓励创造新的知识，而不是记忆以前建立的信息。此外，还计划在网站上免费提供START软件，并通过会议和期刊广泛传播成果。

Sketched-Truss Recognition Tutoring SystemImproved Student Learning through Active Learning and Immediate Student FeedbackResearch (91) The project is designed to evaluate and refine a sketch recognition tutoring system for trusses that enhances engineering learning by providing intelligent and immediate feedback. Through a study of student learning and the revision of the software based on the study's findings, this work provides a springboard for future development of tutoring systems for a much wider array of engineering courses including, but not limited to thermal sciences and a range of other mechanics-based classes. The software actively engages the student while providing guidance and develops a cognitive scaffold between concepts students understand to deeper levels of learning. Most professors are aware of the importance of open-ended problems for deepening learning and enhancing innovation skills. Intellectual Merit: The STRAT (Sketched-Truss Recognition and Analysis Tool) facilitates the incorporation of open-ended design problems into large traditional classes. STRAT software is designed to provide a more efficient means to teach engineers basic mechanics concepts thus allowing study time to be more productive and additional material to be added to the curriculum. Users draw diagrams as they would naturally and thus there is no steep learning curve associated with this tool unlike tool palette or other CAD-based programs. Furthermore, very minimal hardware is required; a standard computer and mouse is adequate. The project has two goals. The first goal is to measure the effects on student learning of the STRAT software through both quantitative and qualitative methods. The second goal of the project is to refine and improve the STRAT software based on experimental data, customer needs collected from students and professors, and on user feedback. To increase external validity and utility, STRAT is being tested in a classroom setting.Broader Impact: The STRAT software has the potential to profoundly increase student learning and the efficiency of the instructional process. The STRAT tool can be used at a variety of institutions of higher learning ranging from small classrooms at teaching focused schools to public research focused universities with very large classrooms. Visual aids are common in civil and mechanical engineering but active sketching and feedback provides additional benefits. Providing immediate feedback improves learning by eliminating the possibility of reinforcing inaccurate assumptions produced by the learner. The sketch tool also encourages users to actively process the information instead of passively viewing visual representations. The task of free-sketching encourages and demands, that learners actively construct their knowledge leading to higher levels of comprehension and longer term learning. This approach to learning is also particularly suited for the sciences as it encourages the creation of new knowledge rather than the memorization of previously established information. Furthermore, there are plans for the STRAT software to be freely available on a website and results broadly disseminated through conferences and journals.
