SALVAR+: Developing Responsible Educational Technologies in the LLM Era

This dataset supports the paper “SALVAR+: Developing Responsible Educational Technologies in the LLM Era”. It contains materials related to the design, development, and evaluation of the SALVAR+ mobile application, aimed at supporting first aid education for laypeople.The dataset includes:Usability evaluation data collected using the System Usability Scale (SUS)Emotional response data collected through EmocardsAggregated and anonymized participant responsesSupporting materials used in the studyThe application was developed based on human-centered design principles and educational software engineering practices. The evaluation involved participants without healthcare training, focusing on usability, perceived experience, and learning support.This dataset is intended to support reproducibility and further research in engineering education, human-centered design, and responsible educational technologies.本数据集支撑论文《SALVAR+：大语言模型（LLM）时代负责任教育技术的开发》。其收录了与SALVAR+移动应用的设计、开发及评估相关的全部材料，该应用旨在为普通民众提供急救教育支持。本数据集包含以下内容：采用系统可用性量表（System Usability Scale, SUS）采集的可用性评估数据、通过Emocards收集的情绪响应数据、经汇总与匿名化处理的受试者反馈数据，以及本研究中使用的各类辅助材料。该应用基于以人为中心的设计原则与教育软件工程实践开发完成。本次评估的受试者均未接受过医疗相关培训，评估重点覆盖可用性、感知体验与学习支持三大维度。本数据集旨在支撑工程教育、以人为中心的设计以及负责任教育技术领域的可重复性研究与后续拓展研究。
