This article reports on a research case study about raising the motivation of young boys and girls (14-16 years old) toward science, technology, engineering, and math (STEM) education to increase their prospects of choosing a relevant career. Using the Internet of Things (IoT) at the core of a design-based methodology, multiple implementations of IoT-oriented educational scenarios (ESs) were realized in different educational contexts. More than 150 secondary students and nine teachers, in seven different settings, were involved in an integrated educational framework with hands-on activities and teamwork. Using a concrete evaluation methodology exploiting both quantitative and qualitative data collected before, during, and after the interventions, we analyze the students' and teachers' experience to understand critical parameters and provide directions for successful ESs. Our findings show that the IoTbased ES realizations were successful overall and enhanced STEM career awareness and skills, with boys showing greater appreciation than girls. Different ES timeframes resulted in different conclusions, while proper organization and preparation in all aspects involved in the realization are critical.

通过物联网实践教育活动培养中学生的 STEM 职业意识：经验和教训

本文报告了一项研究案例研究，该研究旨在提高年轻男孩和女孩（14-16 岁）对科学、技术、工程和数学 (STEM) 教育的积极性，以增加他们选择相关职业的前景。以基于设计的方法论为核心的物联网 (IoT)，在不同的教育环境中实现了面向物联网的教育场景 (ES) 的多种实现。超过 150 名中学生和 9 名教师在七个不同的环境中参与了一个具有动手活动和团队合作的综合教育框架。我们使用具体的评估方法，利用在干预之前、期间和之后收集的定量和定性数据，分析学生和教师的 了解关键参数并为成功的 ES 提供指导的经验。我们的研究结果表明，基于 IoT 的 ES 实现总体上是成功的，并增强了 STEM 职业意识和技能，男孩比女孩表现出更多的欣赏。不同的 ES 时间框架会导致不同的结论，而在实现所涉及的各个方面进行适当的组织和准备至关重要。
