Because today's students often have a fragmented and incomplete understanding of the microscopic world, they do not have a knowledge base from which to make informed decisions on issues like nuclear power or the safe storage of nuclear waste. This project, a collaboration between physics and chemistry educators, is developing inquiry-based instructional materials to help students who are not majoring in science build more robust and coherent mental models of atomic-scale phenomena. The course is intended to help students understand phenomena like the origin of radioactive particles, the difference between ionizing and electromagnetic radiation, and the basic mechanism of tissue damage when exposed to radiation. The project incorporates both computer simulations and effective, inexpensive experiments into its instructional approach. As part of the project, a "concepts assessment" for these types of phenomena is being developed and tested.

由于今天的学生对微观世界的理解往往是支离破碎和不完整的，他们没有一个知识基础，无法在核电或核废料安全储存等问题上做出明智的决定。 这个项目是物理和化学教育工作者之间的合作，正在开发基于探究的教学材料，以帮助非科学专业的学生建立更强大和连贯的原子尺度现象的心理模型。 本课程旨在帮助学生了解放射性粒子的起源，电离辐射和电磁辐射之间的区别以及暴露于辐射时组织损伤的基本机制等现象。该项目将计算机模拟和有效，廉价的实验纳入其教学方法。 作为该项目的一部分，正在为这些类型的现象制定和测试“概念评估”。
