This is the external Internet root index (home) page for MR 3419 - Atmospheric Effects on Electromagnetic Systems. This page is primarily intended for persons who are evaluating the course and to serve as a guide for the online material that is available for this course. Normally, students in this course would not need to access this page; rather they would reach the online material through the Blackboard web site. If you would like a quick overview of this course you can go to the course information, the course material introduction and learning objectives pages. The course material is still under construction; there is considerable material that has been developed, but is not yet ready to be displayed online. To get an idea of the educational level of the material that will be in all modules, check out the online material in Module 3. To see an example of student-computer interaction go to the AREPS Exercise.
Interaction and stimulation
We believe that in order to succeed in an online learning experience, students need continuous motivation and stimulation. This is difficult in the online setting where the instructor's enthusiasm, instant interaction, eye contact and body language cannot be used. In order to overcome this drawback, we will strive to present the material using a considerable amount of visual graphics, including animation and computer-student interaction that provides instant feedback. Students will also interact with each other and with the instructor on a regular basis. They will be encouraged to share their relevant experiences and ideas with the class in weekly online discussions.
We anticipate that many of the students for this course, who will be in the US military, will have busy schedules with many other duties, some of them unexpected. They also may be located at various time zones around the world. We wish to make the course as flexible as possible to accommodate these busy students. For this reason, there will be no set times when students must be online; none of the student-student and student-instructor interactions will require "instant" or "chat room" type feedback from the students. Also we have designed the course into self-contained modules (with the exception of the the first two modules, which contain course logistics information and basic background material that all students will need). If students are unable to complete one module, they can proceed with the following modules and perhaps complete the missed module when the course is offered again.
Motivation and Participation
Although flexibility on a daily basis will be accommodated, experience has shown that online courses based on a "work at your own pace" schedule rarely succeed. For this reason, the students will be expected to participate in all aspects of the course on a timely basis, i.e. some feedback will be required at least three times each week. In order to have successful online discussions, the student will be required to contribute and respond on a timely basis, to get credit for a particular module.
The student will be guided through this course primarily by material offered within Blackboard or through links provided therein. In particular the following Blackboard features will be utilized:
Introductory E-mail Letter - A version of this letter will be sent to all students several weeks before the class begins.
Module 1 - Course Introduction and Logistics
Module 2 - Introduction to Electromagnetic Radiation
Advanced Material: (Not required for 2000 level course)
Module 3 - HF and Lower Frequency Radiation
Module 4 - VHF, UHF and EHF Radiation: Tropospheric effects
Module 5 - UHF and EHF Radiation: Surface Layer effects
