Design, Construction, and Evaluation of a Multi-author Interative Tutorial for Carbonate Petrology

地质学(42)这个项目正在开发一个数字碳酸盐岩岩石学教程，由一个由60到80个带有密集注释的虚拟薄片组成的库组成。每个虚拟薄片都是以分层的PDF文件格式构建的。正在为每个薄片构建由平面偏振光、交叉偏振光、比例尺网格和映射特征组成的图像层。每个图像都添加了可折叠的文本框(弹出式注释)，用于对薄层中感兴趣的选定特征进行注释。薄片的注释是由许多不同的人开发的，教程中包括了薄片的不同解释。本教程建立在以前成功的砂岩岩石学数字教程中获得的多媒体课程开发和评估经验的基础上，并代表着开发用于教授岩石学高度可视化材料的资源的下一步。完成后，材料将出版，很可能由非营利性社会出版商(AAPG、SEPM、GSA等)出版。此外，描述该教程的论文将被提交给适当的期刊。该材料的评估方式将与之前成功的砂岩岩石学教程相同。2005年秋季，一个现有的80-100名学生的碳酸盐班级作为对照组。本课程的后续课程将在所有参与学校的三个学期中使用辅导材料。在此期间，将就材料的准确性、平衡性和对本科生的整体适宜性征求教员的意见。学生对碳酸盐岩石学的理解将在控制组和使用过该教程的后续学期的学生之间进行比较。

Geology (42)This project is developing a digital carbonate rock petrography tutorial consisting of a library of 60 to 80 densely annotated virtual thin sections. Each virtual thin section is being constructed in a layered PDF file format. Layers consisting of images in plane-polarized light, cross-polarized light, scale grids, and mapped features are being constructed for each thin section. Collapsible text boxes (pop-up notes) are being added to each image for annotation of selected features of interest in the thin section. Annotations for the thin sections are being developed by a number of different individuals and differences of interpretation in thin sections are being included in the tutorial. The tutorial is building on experiences in multi-media curriculum development and assessment gained in a previous successful digital sandstone petrography tutorial and represents the next step in development of resources for teaching highly visual material in petrography.When complete, the material will be published, most likely by a non-profit society publisher (AAPG, SEPM, GSA, etc.). In addition, papers describing the tutorial will be submitted to appropriate journals. This material will be evaluated in the same manner as the previous successful sandstone petrography tutorial. An existing carbonate class with 80-100 students acted as a control group in the Fall of 2005. Subsequent offerings of the course will use the tutorial materials for three semesters at all participating schools. During this time faculty input will be sought concerning the material's accuracy, balance, and overall appropriateness for undergraduate students. Student understanding of carbonate petrography will be compared between the control group and subsequent semesters of students who have used the tutorial.
