Training students in basic concepts of physics, such as the ones related to mass, volume, or density, is much more complicated than just stating the underlying definitions and laws. One of the reasons for this is that most students have deeply rooted delusions and misconceptions about the behavior of objects, sometimes close to magical thinking. Many innovative and promising technologies, in particular Virtual Reality (VR), can be used to enhance student learning. We compared the effectiveness of a serious immersive game in teaching the concept of density in various conditions: a 2D version in an embedded web browser and a 3D immersive game in VR. We also developed a specific questionnaire to assess students' knowledge improvement. Primary results have shown an increase in learning efficiency using VR. Also, most students were able to see the shortcomings of their initial theories and revise them, which means that they improved their understanding of this topic.

翻译：培养学生对物理基本概念（如质量、体积或密度）的理解，远比简单陈述其定义和定律更为复杂。原因之一在于，大多数学生对物体的行为存在根深蒂固的错觉和误解，甚至接近巫术思维。许多创新且前景广阔的技术，特别是虚拟现实（VR），可用于增强学生的学习效果。我们比较了沉浸式严肃游戏在不同条件下教授密度概念的有效性：嵌入网页浏览器的二维版本与VR中的三维沉浸式游戏。我们还开发了专门的问卷来评估学生的知识提升情况。初步结果显示，使用VR可提高学习效率。此外，大多数学生能够认识到自身初始理论的缺陷并进行修正，这意味着他们对该主题的理解得到了提升。
