DESCRIPTION (provided by applicant): Challenge Area 12: Science, Technology, Engineering and Mathematics Education (STEM). Specific Challenge Topic 12-OD-104, innovative approaches to STEM education. Our goal is to develop an undergraduate biology laboratory module that is superior to materials that are currently available for teaching scientific thought and engaging students, yet is simple enough in its execution that instructors will be likely to adopt it in large enrollment lower level biology courses (where the teaching of scientific thought is most often deficient). The specific materials that we will develop are DNA markers for Fast Plants (rapid cycling Brassica rapa) and a laboratory module called the Paternity Testing with Fast Plants Lab. In this lab, students will conduct matings to create a paternity dispute and then use DNA markers to identify the father of the offspring. Fast Plants are obligate outcrossers (the do not self-pollinate) and the strains used are genetically diverse, so the data that the students obtain accurately reflects human genetic data. While there are other DNA analysis and paternity testing simulations available, our materials will be distinct in that the student's the experience will be actual experiment. Students will be working with live organisms rather than prepared samples. To facilitate true experimentation, we will develop Fast Plant strains with polymorphism for the DNA markers so that each student in a class can obtain unique results that will challenge their analytical thinking skills. To make sure that our lab module is actually used by instructors, we will design the markers (PCR-RFLP and VNTR) and accompanying protocols so that work can be performed under the time and budget limitations of a typical undergraduate teaching lab. After we develop these materials, we will perform a pilot assessment of them as a lab experience for students in our university's introductory biology course. We hypothesize that our lab module will be better suited to use the the Learning Cycle style of teaching. The Learning Cycle method has been tested rigorously for its effectiveness in a variety of disciplines, including genetics, and found to be effective. Our contribution is to develop materials that allow a college biology instructor to use this method for teaching. This proposal is in response to Specific Challenge Topic 12-OD-104, innovative approaches to science, technology, engineering and mathematics education. The human health significance of our project is in the training of the next generation of health professionals and informed consumers. Undergraduate science education, especially at the introductory level often fails to engage students or teach scientific reasoning, but rather emphasizes rote memorization, but the materials we will develop will engage students and facilitate the teaching of the scientific reasoning.

描述（由申请人提供）： 挑战领域12：科学，技术，工程和数学教育（STEM）。具体的挑战主题12-OD-104，创新的方法，以干教育。我们的目标是开发一个本科生生物实验室模块，是上级的材料，目前可用于教学科学思想和吸引学生，但在其执行足够简单，教师将可能会采用它在大招生较低水平的生物课程（科学思想的教学往往是最缺乏的）。我们将开发的具体材料是快速植物（快速循环芜菁）的DNA标记和称为快速植物实验室亲子鉴定的实验室模块。在这个实验中，学生将进行交配，以创造一个亲子纠纷，然后使用DNA标记来确定后代的父亲。快速植物是专性异交（不自花授粉），使用的菌株是遗传多样性的，所以学生获得的数据准确地反映了人类的遗传数据。虽然有其他DNA分析和亲子鉴定模拟可用，我们的材料将是不同的，因为学生的经验将是实际的实验。学生将与活的生物体，而不是准备好的样品。为了促进真正的实验，我们将开发具有DNA标记多态性的快速植物菌株，以便班级中的每个学生都可以获得独特的结果，这将挑战他们的分析思维能力。为了确保我们的实验室模块实际上被教师使用，我们将设计标记（PCR-RFLP和VNTR）和附带的协议，以便工作可以在典型的本科教学实验室的时间和预算限制下进行。在我们开发了这些材料之后，我们将对它们进行试点评估，作为我们大学生物学入门课程学生的实验室体验。我们假设，我们的实验模块将更适合使用学习周期风格的教学。学习周期方法已经在包括遗传学在内的各种学科中对其有效性进行了严格的测试，并发现是有效的。我们的贡献是开发材料，让大学生物教师使用这种方法进行教学。本提案是对特定挑战主题12-OD-104的回应，即科学、技术、工程和数学教育的创新方法。我们项目对人类健康的意义在于培训下一代卫生专业人员和知情消费者。本科科学教育，特别是入门级的科学教育，往往不能吸引学生或教授科学推理，而是强调死记硬背，但我们将开发的材料将吸引学生并促进科学推理的教学。
