An online portal for collaborative learning and teaching for power engineering education

This paper describes a web-based portal of peer-ranked sites on power engineering for educational purposes. It is a free and open resource consortium for faculty and students in power engineering. As the Internet is developing into a main educational tool, this multimedia-based application offers the educator and the student access to numerous power engineering resources. While it is possible to obtain information using one of the many popular Internet search engines, the results may not be relevant to the desired search topic. The portal described in this paper has individual hyperlinks to various web sites on power engineering that have previously been reviewed and ranked by both established faculty and students according to the versatility of each site. Peer-ranking influences the users' choice for extracting relevant information. Qualitative and quantitative statistical indexes are utilized to rank the web sites. Educators may use the resources available on the portal for educational purposes in a classroom setting. An analysis of the effectiveness of this portal on power engineering education is also offered in the paper.

Reducing the information overload: a method on helping students research engineering topics using the Internet

Students are using the Internet as a primary source of information when researching topics for reports, presentations, or research. Because of the vast amount of data currently available, students need assistance developing an approach to gather this information. Without a proper plan on how to obtain information, they will waste countless hours, and become very frustrated at the process. This paper describes several methods for searching for technical information on the Internet, as related to both electrical engineering and electrical and computer engineering technology (ECET). These methods were presented to students in several ECET classes at New Jersey Institute of Technology. The students were then required to develop presentations on technical topics within their discipline, using several of the sites described in this paper. This paper also suggests a hierarchy in using these various methods, depending on the type of search required. While the initial concept in developing these techniques was to present a method for student information gathering on the Internet, the author has used many of these techniques for class lectures, as well as research topics. Therefore, the techniques presented in this paper are also pertinent to faculty research and teaching.     

A Proposal for Broadening the Education of Power System Engineers

Engineering education has placed its major emphasis on developing graduates with a high degree of technical competence in the traditional engineering disciplines. However, society's expectations for the role of an engineer now reflect the increased concern for inclusion of social policy considerations in engineering decision making. Engineering education must respond to these changes so that engineers will be better prepared to meet today's changes. The authors have focused their discussion on suggested modifications to the power system engineering curriculum as an example of the changing needs of a typical engineering program. The paper discusses some of the limitations the authors perceive in the present education of most power system engineers including a lack of study of nontraditional alternatives to central station power generation. Many of the suggested topics can be added to existing courses; for example, power system planning which could be expanded to cover topics such as load management systems and innovative rate designs which influence load patterns. The addition to the curriculum of a course which provides engineers with a broad overview of the laws affecting engineering decisions and the social policy these laws seek to implement is recommended. Such a course should broaden an engineer's perspective of his/her role in society. The authors feel that this overall proposal is responsive to the needs to be faced by many of the future power engineering graduates. The suggested curriculum changes and additions should aid power system engineers in understanding their role in solving society's energy-related problems.     

Education for Electric Power Engineering

This invited paper was presented at the Second Panamerican Congress of Mechanical and Electrical Engineering. A one-year graduate program in electric power engineering has been in operation at Rensselaer Polytechnic Institute since the fall of 1962; it has been quite successful, with the number of participating students increasing tenfold in this five-year period, from three students in 1962 to thirty-five students in 1967. Among a total 10 percent of students from outside the United States in the program, some are from South American countries. This program is based on engineering education, with emphasis on the electrical phase, acquired in studies leading to a first degree on the bachelor level. Completion of the program results in the Master of Engineering degree. The students devote about half of their time to electric power engineering topics, and the other half to advanced studies covering engineering economics, mathematics, and applied physics. A suggested syllabus includes a variety of recommended courses which enable the student to develop a coordinated program that is general enough to provide a well-rounded foundation for continued studies in specialized areas.

Engineering your electrical engineering education

Electrical and computer engineering (ECE) courses are usually structured in such a way to provide the student with the basics to solve problems in the field and then challenge the student with increasingly more difficult problems to effectively stretch those basic problem-solving approaches into more advanced techniques. While most of this problem-solving focus is placed on the technical arena, this is only one part of the educational experience for an ECE student. There are many nontechnical facets to one problem-solving repertoire that require development to become a successful practicing engineer in industry or academia after graduation. This article serves to provide some of these facets in a career-direction informational guide to junior- and senior-level undergraduate students and graduate students early in their ECE career. It also serves as a guide to outline some useful strategies not found in an engineering text to maximize one's educational experience at the undergraduate and graduate levels as well as the transition between them.
