由于工程领域和研究的迅速全球化，工程专业的学生需要在国际水平上用英语展示他们的研究成果。然而，许多工科学生对说英语感到焦虑；因此，需要通过提供模拟会议环境来对他们进行适当的培训。在这项研究中，作者开发了虚拟现实（VR）培训材料的原型，供工程专业的学生在国际会议上练习和体验英语沟通的困难情况。通过测量参与英语会话培训师的 VR 培训和评估课程的受试者额叶皮层血红蛋白 (Hb) 浓度和心率的变化，研究了该材料的效果。 VR训练前后获得的受试者生理数据测量结果显示，他们在训练后的模拟问答环节中回答困难的英语问题时更加放松。结果表明，VR培训材料可以减少需要用英语进行演讲的工科学生的焦虑，从教育角度来看，这种类型的学习材料有望得到有效利用。
Due to the rapid globalization of engineering fields and studies, engineering students are required to present their research in English at an international level. However, many engineering students feel anxiety for speaking in English; thus, proper training is necessary for them by providing a simulated conference environment. In this study, the authors develop a prototype of virtual reality (VR) training material for engineering students to practice and experience difficult communication situations in English at an international conference. The effects of the material were investigated by measuring the changes in the hemoglobin (Hb) concentration of the frontal cortex and heart rates of subjects who participated in the VR training and evaluation sessions with an English conversation trainer. The physiological data measurements obtained from the subjects before and after the VR training showed that they were more relaxed when responding to difficult English questions at a mocked question-and-answer (Q&A) session after the training. The result indicates that the VR training material can reduce the anxiety of engineering students who need to give a presentation in English, and this type of learning material is expected to be effectively used from an educational standpoint.
