随着高中课程改革的深入，在修订的语文高中课程标准中，新增内容标准，出现了整本书阅读与研讨。在教育部统编版高一下册的语文教材中选用《红楼梦》作为整本书阅读的内容，帮助学生了解中国文化同时提高学生的语文素养。但在实际教学中，学生对于书本知识的了解不够深入，本文探索了基于3D虚拟世界的《红楼梦》STEAM校本课程开发，设计出课程的整体框架、内容以及安排，并完成了所有课时的教学设计，为教师开展课程提供思路。同时以《刘姥姥进大观园》为例进行虚拟场景的设计与实现，根据书本描述及理解设计并制作出刘姥姥、贾母等人的人物形象、大观园大致环境布局及部分室内装饰，对《刘姥姥进大观园》故事情节进行改编。通过《红楼梦》中人物、环境、情节的创造与再现，强化学生对书本内容的理解与掌握，提高学生的核心素养。
