      SUMMARY OF TEACHING EXPERIENCE: RAMBABU BOBBA

    •  

      1. I have been teaching or taught the following courses in the Department of Physics: Solid State Physics (472), 2. Quantum Mechanics (435), 3. Modern Physics (271), 4. General Physics (221 and 222) (Lecture, Recitation and Laboratories) 5. Elementary Physics (141), 6. Earth Science (201 and 202), 7. Physical Science (101 and 102) and 8. Special Problems in Physics.
      2. I have been teaching in this University since Fall 1986 and have taught large number of students (over 150 students per semester) in non science, science and engineering curriculums. During my tenure at Southern University, I have come across the best and brightest, underprivileged, and even incarcerated individuals who are enrolled in the College courses. My approach in teaching is to reach the level of the student at the beginning and pull him or her to higher level of thinking in order to solve the problems. An evidence to justify the fact can be seen from the student reports. 3. Developed Physical science course syllabus for LaSIP proposal using critical thinking skills and strategies. Involved in the on going educational reforms at Southern University. Teaching Physics for students in Howard Hughes Biomedical pre College and Out reach Program.  I was involved in developing the SEA summer workshop for science teachers in Louisiana.
      3. I have the opportunity to guide the students for their term papers, undergraduate research projects and introducing them to research and summer employment. My objective is to involve, motivate and prepare our students for the graduate schools and for employment in national laboratories and industrial organizations. On an average two of my students every academic year since 1986 presented their work in national conferences.
      4. I was actively involved in the development of MS program in physics at Southern University.
      5. Developed ongoing collaborations with teaching and research faculty in few universities in India, Thailand, and Japan for student and faculty exchange and submitted proposals for funding through NSF-Materials World Network.
      6. Prior to the initial employment at Southern University, I have served as a faculty member equivalent to the rank of Assistant Professor for over five years (1980-1985) in Gandhi Institute of Technology and Management and Nagarjuna University, India. During that period, I have developed freshmen and sophomore Physics laboratories for engineering curriculum and taught 1. Electromagnetic Fields and Waves 2. Heat and Thermodynamics 3. Sound 4. Light 5. Electricity and Magnetism and 6. General Physics courses.
