Collaborative Research Improving Representational Competence

项目摘要

This project is a collaboration between Whatcom Community College engineering and math faculty and Western Washington University psychology faculty. The project will investigate how to help students develop representational competence, a key skill needed for success in STEM fields. The project will design learning activities connected to physical models created by 3D printers and assess the impact of these activities on student learning. By creating 3D models that students can grasp in the hands, teachers may be able to help students learn key concepts in the classroom. If these 3D models help students gain skills in math and use those skills in other STEM courses, the students may be more likely to succeed and graduate. This project will test this 3D model approach and will help researchers understand how to best prepare engineering and other STEM students from a variety of backgrounds for STEM success. This project has the potential to increase both the number and diversity of STEM students who earn a degree and gain future employment in engineering and other high demand STEM fields. The project will share designs for the 3D models and related teaching material with other institutions. Teachers across the country will be able to add these tools to existing courses without the need to create new courses or change entire programs, creating a simple and efficient way to help STEM students learn better.A growing body of research indicates that well-developed spatial skills are prerequisite to the development of representational competence (i.e. the fluency with which a subject expert can move between different representations of a concept as appropriate for learning, communicating or problem solving). Additionally, it is known that these spatial skills can be improved through targeted training. With the advent of 3D printing technologies, faculty have a powerful tool readily available to develop physical models for learning activities that target specific learning goals. The project team will develop and assess physical modeling activities and supporting curriculum specifically designed to target development of representational competence. With three years of funding, this project proposes three goals: (1) Develop physical models and associated learning activities that embed practices thought to develop representational competence in multiple content areas in Statics and Integral Calculus; (2) Assess the effectiveness of the models and activities on improving representational competence in the context of traditional coursework in Statics and Integral Calculus; and (3) Identify the characteristics of modeling activities that make them effective for all learners and/or subgroups of learners. The project will develop replicable modeling curriculum for these classes with sets of activities and model designs. The project will also make available a rubric and taxonomy to classify various attributes of model-based learning activities, serving as a case study for applying this framework to other disciplines.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个项目是Whatcom社区学院工程和数学系与西部华盛顿大学心理学系之间的合作。该项目将研究如何帮助学生发展代表能力，这是在STEM领域取得成功所需的关键技能。该项目将设计与3D打印机创建的物理模型相关的学习活动，并评估这些活动对学生学习的影响。通过创建学生可以掌握在手中的3D模型，教师可以帮助学生在课堂上学习关键概念。如果这些3D模型帮助学生获得数学技能，并将这些技能用于其他STEM课程，学生可能更有可能成功并毕业。该项目将测试这种3D模型方法，并将帮助研究人员了解如何最好地准备工程和其他STEM学生从各种背景的STEM成功。该项目有可能增加获得学位并在工程和其他高需求STEM领域获得未来就业的STEM学生的数量和多样性。该项目将与其他机构分享3D模型的设计和相关教材。全国各地的教师将能够将这些工具添加到现有课程中，而无需创建新课程或更改整个课程，越来越多的研究表明，良好的空间技能是发展表征能力的先决条件（即，学科专家可以在适合于学习、交流或解决问题的概念的不同表示之间移动的流畅性）。此外，众所周知，这些空间技能可以通过有针对性的训练来提高。随着3D打印技术的出现，教师有一个强大的工具，随时可以开发针对特定学习目标的学习活动的物理模型。项目团队将开发和评估物理建模活动，并支持专门设计的课程，以发展代表能力。本计画为期三年，提出三个目标：（1）发展物理模型及相关学习活动，以嵌入在静力学与积分学的多个内容领域发展表征能力的实践;（2）评估模型与活动在静力学与积分学传统课程背景下提高表征能力的有效性;以及（3）识别建模活动的特征，这些特征使它们对所有学习者和/或学习者的子群体有效。该项目将为这些课程开发可复制的建模课程，包括一系列活动和模型设计。该项目还将提供一个标题和分类法，对基于模型的学习活动的各种属性进行分类，作为将该框架应用于其他学科的案例研究。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
