The article profiles a project addressing a central issue in reform-driven STEM education – the need to align educational experiences with real-world STEM. We profile an interdisciplinary project which aimed for authenticity by: 1) purposefully designing an authentic PBL project and 2) incorporating STEM professional volunteers as facilitators. Volunteers enhanced authentic elements of the project task (e.g., open-ended task, accountability) and context (e.g., autonomy, collaboration). Volunteers alleviated pedagogical barriers to PBL – their expertise allowed both volunteers and teachers to take up the facilitator roles foundational to PBL. Professional volunteers can play vital roles in STEM capacity-building initiatives, including those seeking to broaden participation. Further research is needed to understand how to best prepare and utilize volunteers in a variety of classroom roles, including as PBL facilitators.

通过吸引 STEM 专业志愿者来提高 PBL 的真实性

这篇文章介绍了一个项目，该项目解决了改革驱动的 STEM 教育中的一个核心问题——需要使教育经验与现实世界的 STEM 保持一致。我们通过以下方式介绍了一个旨在实现真实性的跨学科项目：1）有目的地设计一个真实的 PBL 项目和 2）将 STEM 专业志愿者作为促进者。志愿者增强了项目任务（例如，开放式任务、问责制）和背景（例如，自主性、协作）的真实元素。志愿者减轻了 PBL 的教学障碍——他们的专业知识使志愿者和教师都能担任 PBL 的基础促进者角色。专业志愿者可以在 STEM 能力建设计划中发挥重要作用，包括那些寻求扩大参与的计划。
