Scaffolding Effective Practice for Use of Animations in Teaching Mineralogy and Physical Geology

42（地质学）正在开发六对计算机动画和可视化工具，用于物理地质学和矿物学教学。每个动画对的前半部分适合在地球科学课堂上使用。教师展示这些动画，同时提供线索，以帮助学生的视觉信息的分析。每对动画的后半部分包括适合家庭作业或远程学习作业的在线交互式网络练习。动画的风格和内容是一致的，使公约，符号和空间关系从一个动画延续到下一个，提高学生学习的好处。动画托管在一个网站上，致力于搭建动画教学的有效实践，不仅包括动画本身，还包括动画使用的最佳实践资源，地质学和矿物学教学中特定学习挑战的信息，以及评估动画使用的工具。这些动画正在由一小群当地用户进行初步测试，以便进行形成性评价。修改后，改进后的动画将被嵌入到一个丰富的网站，将提供内容和上下文之间的关系，学生通过动画学习的例子。全国各地的一批用户自愿测试网站和动画，并在美国地质学会全国会议的一次聚会上提供反馈。其成果将有助于充实有关在基础地球科学课程教学中有效利用计算机动画的知识库。

42 (Geology)Six pairs of computer animations and visualization tools for use in teaching physical geology and mineralogy are being developed. The first half of each animation pair is suitable for use in geoscience classrooms. Instructors show these animations while providing cues to aid in students' analysis of the visual information. The second half of each animation pair consists of an on-line interactive web-based exercise suitable for homework or distance-based learning assignments. The style and content of the animations are consistent throughout so that conventions, symbols, and spatial relations carry over from one animation to the next, improving the benefits to student learning. The animations are hosted on a web site dedicated to scaffolding effective practice for teaching with animations, and include not only the animations themselves, but also resources on best practice for use of animations, information on specific learning challenges in teaching geology and mineralogy, and tools for evaluating the use of animations. The animations are being initially tested by a small group of local users for formative evaluation. After revisions, the improved animations will then be embedded in a rich web site that will provide examples of the relationships between content and context for student learning through animations. A cadre of users across the country has volunteered to test the web site and the animations and provide feedback at a gathering at the Geological Society of America National Meeting. The outcome will be a contribution to the knowledge base relating to effective use of computer animations in teaching fundamental geoscience curricula.
