The major changes in the courses include: [1] studio and interactive teaching [2] more hands-on experiments. I have introduced the studio teaching style in Optics I and Optics II and I used computers to assist in the experiments and lectures. I have written computer software for the courses, and the entire lectures were given in a computer-optics room, which was equipped with several computers and three optical tables. It holds 7 groups (14 students) for both lectures and experiments. I also have used my two laboratory rooms for hands-on experiments. Based on the positive evaluation, I am expanding this program to a larger scale. In order to offer an institute-wide course, I plan to add 12 more computers and 4 more optical tables for our rapidly expanding program. My short-term goal for this program is to improve the teaching room and to offer both computer-based lectures and hands-on experiments to 20 groups (40 students). I have been awarded a NSF-CAREER grant for undergraduate education. I have emphasized student-faculty interaction in undergraduate courses. Specifically, I have adopted and modified the method of interactive teaching, which was recently developed by Prof. Mazur at Harvard University. During my lectures, I did not recite the material covered in the textbook, but rather, I initially provided an introduction and discussion of the key paradigms and concepts, then assisted the students as they worked in groups to discover the rest. I moved some problems, initially designated as homework assignments, into the class for group discussion, and used class performance to partially determine a student's final grade in the course. I have found that the interactive teaching method has improved student motivation by allowing them to focus on the essential concepts while developing their understanding through classroom discussion. To accommodate the individual abilities of students at different educational levels, I have offered optional lectures for both advanced students and for those who require extra tutorial attention. To integrate exposure to actual research activities with the material I was introducing to them in the classroom, I arranged for three laboratory excursions during my 1993-94 Solid State Physics course. The undergraduates visited Rensselaer's 5,700 ft2 Class-100 clean room and six advanced solid-state physics laboratories. I hoped that the combination of my lecture methodology and laboratory visits would make the course more attractive to undergraduates, and I was pleased to discover that the majority of comments made by the students were very positive. I am led to believe that interactive teaching is a very positive way to improve student learning and motivation. One of the most important changes to my undergraduate courses was the increase of the weight of the laboratory experiments. In my three undergraduate courses, 40%-50% of the course was laboratory work, and I used a laboratory test to replace the midterm written test in optics courses. Some lectures I gave were mixed with experimental demonstrations. The responses to laboratory experiments in the courses by both physics and non-physics students were very positive. I have established an exchange program for both graduate and undergraduate students with the Institute of Physics, Chinese Academy of Sciences. This program is supported by the NSF (US) and NNSF (China). In last four years, I sent 13 students (both graduates and undergraduates) to Beijing and Tyoko for several research projects. In the spring of 1996, our pilot program in 1995 was selected as an international exchange program model by the International Division of the United States National Science Foundation, and we were awarded $100,000. A private Chinese company, 505 International Company, donated $250,000 for our exchange program. We have since sent 7 students to China, and we will send 16 more students (both graduates and undergraduates) and 10 U.S. scientists to China for international collaborations in the next four years. The first U.S. scientist partly supported by this program is Prof. Ivar Giaever (Noble Laureate). He has visited China and has given several talks in 1995. In the spring of 2006, I introduced a new course “THz Science and Technology” (CRN-55797, PHYS4962-01), This course will provide the fundamentals of THz science and technology. We will cover the basic concepts of generation, detection, propagation, and applications of the T-rays. The free-space T-ray optoelectronic system provides diffraction-limited spatial resolution, femtosecond temporal resolution, DC-THz spectral bandwidth and mV/cm field sensitivity. In 2008, I modified the course of THz Science and Technology. This is an introductory course for students and researchers who are interested in mid-infrared and far-infrared pulsed THz radiation. The course will provide the fundamentals of THz science and technology. We will cover the basic concepts of generation, detection, propagation, and applications of T-rays. This course has a good balance between lecture and hands-on lab. Since 1992, I received more than 19 NSF undergraduate educational grants (17 x $10,000 and 2X$6,000) for the research experience for undergraduates. I also received one NSF international grant ($100,000) to support the student training in Asia.
