Teaching Methodology Teaching Aids Classroom teaching will involve lectures, PowerPoint presentations and handouts. Assignments will be given to students which would test their understanding of the lectures and also test their ability to use theoretical knowledge in real life situations. Exercises will be given to students in class that would gauge their ability to assimilate knowledge quickly. Students will have access to EU’s web portal and Internet facilities, enabling them in data searches and computer-aided decision making. Students will have access to the well-stocked library where latest books, periodicals, newspapers, journals, prints and records are available for reading, references and further research. In order to build up the habit of self-learning amongst students, several papers spanning different sectors of Power System would be assigned to each group of two / three students to make a presentation in the class. For the betterment of the understanding of the students a limited period of time may be allotted at the end of the class to allow questions and answers. Spot tests may be conducted to evaluate the performance of the students. Handouts Lecture slides in PPT as well as in printed form Lecture delivery by multimedia projector in addition to white board and marker Online availability of the learning materials through EU web portal Field visit Group work Performance Students will be assessed through rigorous class tests, home assignments, class presentation along with Mid Term and Final Examinations and the marks Evaluation distribution will be as followed: Grading Policy Class Performance( Assignment + Spot tests + Attendance) 10% Class Test Mid Term Final Total 20% 30% 40% 100% The numerical scores earned by a student in the quizzes, tests, exams., etc. during and at the end of the semester are cumulated for assignment of Grades in the following manner : Marks 80-100 75-79 70-74 65-69 60-64 55-59 50-54 45-49 40-44 00-39 Grade A+ A AB+ B BC+ C D F Point 4.00 3.75 3.50 3.25 3.00 2.75 2.50 2.25 2.00 0.00 Submission of Assignment All the assignments should be submitted within specified deadline. If any student fails to submit with in time a percentage of points will be deducted. Without submission of all the given assignments, a student will get an I (Incomplete) grade in the course. Academic Ethics Students are encouraged to discuss the intellectual aspects of assignment with other class participants however; each student is responsible for formulating solutions in his or her own words. Students who submit the same or suspiciously similar assignments will receive a grade zero on the particular assignment and have their final course grade reduced by one letter grade. In addition, the University has formal procedures to handle cases of academic dishonesty. A teacher alone cannot teach; it requires tremendous amount of cooperation and positive responses from the student. So every student should get their lessons by reading various books/materials besides their text books.
