Studying new forms of participation and identity in mathematics classrooms with integrated communication and representational infrastructures

Wireless networks are fast becoming ubiquitous in all aspects of society and the world economy. We describe a method for studying the impacts of combining such technology with dynamic, representationally-rich mathematics software, particularly on participation, expression and projection of identity from a local to a public, shared workspace. We describe the types of mathematical activities that can utilize such unique combinations of technologies. We outline specific discourse analytic methods for measuring participation and methodologies for incorporating measures of identity and participation into impact studies.

从数字画像到数字孪生体:数智融合驱动下数字孪生学习者构建新探

随着AI、5G、物联网、大数据、传感与全息等新兴技术的快速发展,尤其是虚拟现实技术从VR、AR、MR到XR的不断演进,促使数字孪生技术开始走向应用并备受学者关注。其正从制造业、城市管理、医疗服务向社会其他领域不断衍生拓展,并在教育领域呈现出广阔的应用前景。在数智融合驱动下,从“AI+大数据+学习分析”加持下的学习者数字画像,向“AI+5G+XR”与全息技术支撑下的数字孪生学习者的迭代更新,将成为AI赋能教育的一个演进趋势。数字孪生学习者基于“四个关键要素”和“五个基本原则”这一现实前提,遵循刻画学习者画像、仿真学习过程、预测学习发展、生成学习结果和共享学习智慧的生成过程,具有高度仿真、动态映射、虚实共生、迭代进化和智能应用的特征,可为“AI+学习者”呈现更精确的学习过程分析、更精准的学习内容推送、更科学的学习评价与无边界的学习生态;并助力学习者进行学习资源共享、学习行为调整、学习兴趣提高、学习体验改善、学习效率提升。因此,对数字孪生学习者进行前瞻性研究,可为数智融合驱动下的学习变革提供全新的视角与思路。
