Materials Chemistry Case Study Approach to Facilitate Learning the Fundamentals of Chemistry: Introductory College and Secondary Level

9354518舒尔茨该项目将根据材料的性质开发一门化学入门课程。它将是基于发现的，因为学生将在实验室中观察现象，然后利用这些观察来发展对所涉及的化学的理解。该项目的一个主要目标是为学生提供令人兴奋的学习体验。许多科学课程不让学生享受发现和理解的乐趣，这让年幼的孩子和实习科学家都很高兴。虽然对于个人来说，这种情况是令人遗憾的，但对于有抱负的教师来说，这是灾难性的，因为他们将塑造未来领导者的理解。这个项目将把发现的喜悦带回科学课程。例如，原子结构和成键将从动手检查各种金属样品的材料性质开始。脆性材料在与较少近邻的结合中限制了空间方向性，而柔软、延性的材料则扩展了与多个近邻的结合球。学生们将首先被送进实验室进行一次探险之旅。然后，将鼓励全班学生为他们的观察制定一个假设。只有在这一过程之后，教师才会通过有针对性的提问，引导学生认识到结合和结构的重要性。然后，课程将被鼓励推断并将这一理解扩展到未被检查的材料。教育评估员是项目团队的成员。与出版商的初步接触可能会导致通过教科书广泛传播。***

9354518 Shultz The project will develop an introductory chemistry course based upon the properties of materials. It will be discovery based in that students will observe phenomena in the laboratory, then use those observations to develop an understanding of the chemistry involved. A principal goal of the project is to provide an exciting learning experience for the students. Many science courses deny students access to the joys of discovery and understanding that so delights both young children and practicing scientists. While for individuals, this situation is regrettable, for aspiring teachers it is disastrous since they are the ones who will shape the understanding of tomorrow's leaders. This project would put the joy of discovery back into science courses. For example, atomic structure and bonding would start with a hands-on examination of the material properties of a variety of metal samples. The brittle ones have restricted spatial directionality in the bonding with few nearest neighbors while the soft, ductile ones have expanded bonding spheres with many nearest neighbors. Students will be sent into the laboratory for an adventure in exploring first. The class will then be encouraged to develop an hypothesis for their observations. Only after this process, will the instructors, through directed questions, guide the students to realize the importance of bonding and structure. The class will then be encouraged to extrapolate and extend this understanding to materials not examined. A educational evaluator is a member of the project team.
