Multi-Media For a "Hands-On" Oceanography Course

该项目的目的是继续为一系列“动手”多媒体实验室模块开发软件，这些模块是为具有“定量科学”组成部分的低年级海洋学课程设计的。重点是个人和团体的发现，观察和分析最新的地球物理和地理数据，并通过小组讨论和写作的想法的沟通和修改。正在为该项目开发的一些工具提供了以前只有专门从事与该数据相关领域的研究生才能访问的数据。 每个模块都提供了丰富的数据源，以便学生可以根据自己的兴趣和能力进行探索。 模块组织是很容易编程的教师，使广泛的课程需求可以得到满足。因此，每个学生可以接触到可用内容的子集。这鼓励探索和挑战先进的学生做更多的比最低限度。这种可编程性还允许修改各种课程和学术水平的模块。 这些模块旨在用于Macintosh计算机实验室，并设计为在每个2到3小时的实验课程中完成。它们是以一种“开放式”的方式设计的，这样就可以容纳一系列学生的能力。目前资助的NSF项目将完成的三个模块是1）“熟悉地图和地球”，2）“探索深处”和3）“理解深处”。拟开展的新工作包括继续评价、测试、支持和修订现有模块，以及创建一个或多个新模块。 学生写作也在这个项目中得到支持。学生在书写字段中输入文本，并将其保存、检索、打印和“亲手”书写到网络上的普通教师邮箱。还提供了一个随机匿名同行审查系统。学生提交他们的写作，由另外两个人审查。 其他人接收文本并进行注释，然后返回注释后的文本。两端都是匿名的。这样做的一个重要效果是鼓励通常不参与的学生表达自己，并有机会给予和获得反馈，然后根据反馈修改写作。 为了支持这些模块，创建了一个管理图像和图像相关数据的系统。幻灯片被放入PhotoCD，并使用Apple Photo Flash自动裁剪和压缩。 基于HyperCard的“图像库管理员”支持图像数据库文件的文档编制和创建，这些文件确定地图或其他图形图像上的“点击点”（各种形状和颜色的符号，或PICT图像）的位置。该系统具有灵活性和快速性。 初步测试已经完成了两组10名学生和一组5。反馈相当积极。学生们一致称赞材料的“动手”方面。根据这些初步测试，正在进行修改和改进。

The purpose of this project is to continue to develop software for a series of "hands-on" multi-media lab modules intended for a lower division Oceanography course with a "Quantitative Science" component. The emphasis is on individual and group discovery, observation and analysis of the most current geophysical and geographical data, and the communication and revision of ideas through both group discussions and writing. Some of the tools being developed for this project provide access to data that has been previously accessible only to graduate students specializing in a field related to that data. Each module makes available a rich source of data so that the student can explore according to his/her interests and abilities. Module organization is easily programmable by the instructor so that a wide range of course needs can be met. Thus, each student may be exposed to a subset of the content available. This encourages exploration and challenges the advanced student to do more than the minimum. This programmability also allows modifying the modules for a variety of courses and academic levels. The modules are intended to be used in a Macintosh computer lab, and are designed to be completed in lab sessions of 2 to 3 hours each. They are designed in an "open-ended" way so that a range of student abilities can be accommodated. The three modules that will be completed on the currently funded NSF project are 1) "Getting Acquainted with Maps and the Earth", 2) "Exploring the Deep", and 3) "Understanding the Deep". New work to be performed includes the continued evaluation, testing, support and revision of the existing modules, as well as the creation of one or more new modules. Student writing is also supported in this project. The student enters text in a writing field, and saves, retrieves, prints, and "hands-in" writing to a common instructor's mailbox on the network. A system of Random Anonymous Peer Review is also available. Students submit their writing to re view by two others. The others receive the text and make comments, after which the commented text is returned. This is anonymous at both ends. An important effect of this is the encouragement of normally uninvolved students to express themselves, and the opportunity to both give and get feedback, then modify the writing based on that feedback. In support of these modules, a system of managing images and data related to images has been created. Slides are put onto PhotoCD and automatically cropped and compressed using Apple Photo Flash. A HyperCard based "Image Librarian" supports the documentation and creation of the image database files that determine the locations of "clickspots" (symbols of various shapes and colors, or PICT images) on a map or other graphic image. This system is flexible and quick. Preliminary testing has been done with 2 groups of 10 students and 1 group of 5. Feedback has been quite positive. Students uniformly praise the "hands-on" aspect of the material. From these initial tests, modifications and improvements are being made.
