Assessment and Outcomes

The Mission of College of Engineering at Tennessee Technological University states, "Through education, research, and service we will prepare our graduates to integrate their experience as engineers and technologists with cultural understanding to improve life in the region and the world."

The doctoral program in engineering strives to accomplish the mission in whole, more particularly, in research. The degree is a research based one which requires that the graduate demonstrate his/her capability to perform scientifically valid engineering research to find solutions to appropriate problems faced by industry and society in general. The educational aspect of the program delves in preparing the student to gain the knowledge and confidence to perform such research work.

Program Outcomes and Assessment

  1. Increase the enrollment to 50 students in order to exceed comfortably the critical mass of students needed to maintain the program without overstressing the faculty resources. The enrollment in Fall 2004 was 48 students compared to 31 students five years back and well on the way to reaching the goal of 50 students. (See Table 1 - PhD Enrollments and Graduations Fall 2000 - Summer 2005) Historically the vast majority of doctoral students were from ECE and ME departments. Within the past two years ChE and CEE departments have also developed plans to increase their participation and therefore we are on target to reach the goal.
  2. Graduate 7 students per year. Table 1 shows the number of graduates by semesters since Fall 2000 which varied from 5 to 7 per year. The recent enrollment increases should result in increased graduation rates and we expect to accomplish the goal in the next two years as we have sufficient number of students enrolled and making progress.
  3. Graduates employed in positions of responsibility in teaching and/or research. Table 2 shows the last known employment positions of recent graduates. It appears our graduates are working at academic institutions, industry or government with responsibility for research and teaching. The research publications of the students showing their continued professional activity are also shown in Table 2.

Learning Outcomes and Assessment

  1. The student should gain breadth of knowledge in the discipline and depth in the specific area of research topic. The advisory committee is responsible for the development of a program of study including advanced level courses in the discipline and verification that the student takes the courses prescribed. The comprehensive exam is taken at the end of the course work part of the program. The comprehensive exam, administered by the committee, tests the student's breadth and depth knowledge and the readiness to undertake independent research. A student performing successfully on the comprehensive examination has demonstrated the learning of the subject matters and the capability to perform research in the chosen area. The original paper copies of the comprehensive examination are kept in the departmental office for at least 10 years.
  2. The student should learn and gain experience in doing independent academic work. The student is required to take at least 12 hours of course work at the 7000 level which requires significant independent work (laboratory, library, or industry), in addition to the regular class work. This is verified by the committee and the college office before the student is permitted to take the comprehensive examination.
  3. The student should demonstrate his/her ability to identify and define the engineering research problem. The student meets this expected outcome by developing the research proposal and by obtaining the approval of the same from the committee.
  4. The research work performed by the student should be of such a level to contribute to the existing knowledge in the engineering field. First, the student defends the research work to the advisory committee and other professionals in an open meeting by describing the work and answering questions to their satisfaction. Secondly, the students are encouraged to present papers at professional meetings and also publish in journals. Table 3 lists the presentations made by students at professional meetings during 2004-05.

Assessment Results and Adjustments and Modifications to the Program

The Chemical Engineering Department and Civil and Environmental Engineering Department are being encouraged to increase their participation in the Ph.D. program. Recent new faculty hires in these department have been more research oriented and interested in Ph.D. program. This is already showing up as increased enrollment in the program. In three to four years, more graduates will be expected to come out of the program.

The student learning assessment aspect is a continuous process and is less formal because of the relatively small number of students enrolled. However based on such assessments, the following modifications have been implemented.

  1. Every student will undergo a preliminary assessment of his/her knowledge in the chosen field. This will be performed by the respective department prior to finalizing the program of study.
  2. The comprehensive examination will be prepared and administered by the advisory committee when the student has completed most of the required course work. All parts of the examination will be given over a two week period instead of over a semester as was done in previous years.
  3. Actively encourage students to present papers in professional meetings in front of peers and defend their work.
