The course is designed to develop the distinction between evidence and inference as a conceptual framework in the context of mastering a few science concepts. Since precollege science teachers are increasingly held responsible for teaching to the Standards, examples are explicitly drawn from the Standards and conclusions are linked to the Standards. The first three weeks of the course explore the distinction between evidence and inference using a few common exemplars, e.g., the heliocentric view of the solar system and the nature of floating and sinking. The method of teaching is based on the constructionist approach developed by the Epistemology and Learning Group at the MIT Media Lab (http://lcs.www.media.mit.edu/groups/el/), among others. This approach is characterized in the following way: (1) the intended outcome must be clearly understood by the students; (2) achieving the outcome must require the students to act; and (3) students must be able to tell whether their actions are taking them closer to or further from the intended outcome. This approach provides feedback from the task, not from the teacher. For example, students asked to develop a procedure to measure the volume of an object must be able to determine the volume by some other process so that they can determine if the method they devise agrees. They also use a variety of objects upon which to test their proposed solution to the problem.

本课程的目的是在掌握一些科学概念的背景下，发展证据和推理之间的区别，作为一个概念框架。由于大学预科科学教师越来越有责任按照《标准》进行教学，因此从《标准》中明确抽取例子，并将结论与《标准》联系起来。前三周的课程将通过一些常见的例子来探讨证据和推理之间的区别，例如，太阳系的日心说和漂浮和下沉的本质。教学方法基于麻省理工学院媒体实验室（http://lcs.www.media.mit.edu/groups/el/）的认识论和学习小组开发的建构主义方法。这种方法的特点如下：(1)学生必须清楚地理解预期的结果；(2)取得成果必须要求学生采取行动；(3)学生必须能够判断他们的行为是使他们离预期结果更近还是更远。这种方法提供的反馈来自任务，而不是老师。例如，要求学生开发一种测量物体体积的程序，他们必须能够通过一些其他的过程来确定体积，这样他们就可以确定他们设计的方法是否一致。他们还使用各种各样的对象来测试他们提出的问题解决方案。
