1.       Program Outcomes and Assessment

Following the establishment of the educational objectives, a set of educational outcomes was defined for achieving these objectives.  The process for determining Program Outcomes is identical to that used for establishing the program educational objectives.  We involved our constituents: students (through AIAA Student Branch and Sigma Gamma Tau), faculty, industries and government labs, the AE School External Advisory Council, professional societies, and the alumni.

 

The outcomes were first established in 1997, and are revised annually based on the data from our assessment efforts.  A comprehensive review of the expected outcomes is done once every five years.  The most recent review was done during the 2001-2002 academic year.

 

The Web site <http://www.ae.gatech.edu/~lsankar/ABET2002/Constituents.Input.pdf> contains the constituents input in establishing the outcomes.

 

a.     Program Outcomes:

The following Program Outcomes have been established in consultation with our constituents.

 

a)     The graduates of the undergraduate program in aerospace engineering will have an understanding of physics, chemistry and mathematics, and how they pertain to solving real world problems.

b)    They will have a firm understanding of engineering science fundamentals that enables the graduates to examine real world problems for the underlying physical principles, and decide on appropriate methods of solution.

c)     They will have the ability to design, conduct and analyze the results of experiments in order to measure and study physical phenomena.

d)    They will have the ability to analyze and design aerospace structural elements, such as trusses, beams and thin walled structures, taking into account structural dynamics and aeroelastic effects.

e)     They will have the ability to analyze and design airfoils and wings, accounting for viscous and compressibility effects.

f)     They will have the ability to analyze and design air-breathing and rocket propulsion systems.

g)    They will have the ability to analyze the flight dynamics of aircraft and spacecraft, and design flight control systems.

h)    They will have the ability to work in teams and design complex systems such as aircraft and spacecraft, from a preliminary design perspective.

i)      They will have good oral, written and graphical communication skills.

j)      They will be well trained in the role of the engineer in society, and have an awareness of ethical, environmental and quality concerns in the engineering profession.

k)     They will be trained to be life-long learners, pursuing and interested in independent study, research and development.

 

b.             Relationship of the Outcomes to the Courses and the EAC/ABET List of Outcomes: After the list of outcomes was developed, a set of courses and topics was identified.  The semester conversion during the year prior to the fall of 1999 gave our faculty an opportunity to redesign our curriculum and tie the objectives and outcomes of the courses to the program outcomes.  It also gave us an opportunity to take into account our constituents’ input.

 

The table below shows the relationship between the program outcomes and the courses in the aerospace engineering curriculum.  A more detailed table is also provided in Table I-6.

c.             Relationship of the Outcomes to the Educational Objectives: Our constituents view the expected outcomes listed above as the skill sets our students will have at the time of graduation.  The educational objectives describe the expected accomplishments of graduates during their first few years of work in the industry, academia, or a government laboratory.  The expected outcomes are thus crucial to, and closely tied to, achieving our educational objectives.

 

Items (a)-(f) in the above list are aimed at our first educational objective, the development of successful engineers. Items (g)-(j) is related to our second educational objective, the development of successful professionals.  All the items above. and item (k) in particular, directly relate to our third objective of instilling a desire for life-long learning in our graduates.

 

d.     Two-Loop Process in Place for Assessing Outcomes and Evaluating Objectives


We use the following approach, patterned after the EAC/ABET two-loop cycle, to establish, assess, and revise our educational objectives and outcomes:

 

 

               

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


e.     Establishment of Indicators for Success: Until 1999-2000, we used a relative indicator (a significant 10% change in a measurable outcome with the 1999 level as the baseline) to determine if our educational objectives and expected outcomes are being achieved.  As part of the recent comprehensive review of our educational objectives and outcomes in the fall of 2001 and the spring of 2002, the following absolute indicators have been established:

i)      Our graduates will assess themselves as having the engineering skills needed to succeed in their profession at 3.2 (80%) or better, on a scale of 1 to 4.  The employers will also rate our graduates as having the skills needed to succeed in their profession at 3.2 (80%) or better on a scale of 1 to 4.  Our alumni will assess themselves as having technical skills that exceed job expectations.  These three indicators are being used to monitor our first educational objective of developing successful engineers (outcomes a-f).

ii)     Our curriculum has a number of required courses for achieving our second educational objective, and all of our students successfully complete these courses (with the requirement that there are no more than 2 D’s in the entire curriculum).  We have set the following additional indicator for achieving our second educational objective of developing successful professionals (outcomes g, i, j): twenty-five percent of our students will have participated in an undergraduate research project, design experience beyond capstone design, or an industry internship by the time they graduate.  This indicator is consistent with our strategic plan goals.

iii)    The following indicator is used to determine if we are instilling in our graduates the desire for life-long learning (our third educational objective, outcome k).  One-third of our graduates will pursue graduate studies or participate in a continuing education program within their first five years following graduation.

f.      Strategies for Achievement of Outcomes:

 

Our Curriculum  The primary strategy we have in place is the portfolio of courses specifically tailored for achieving the outcomes, and the qualified faculty who are well equipped in training our students.  The table above lists our expected outcomes and the course(s) used towards the achievement of these outcomes.  Each of our courses has a clearly documented set of learning objectives and a set of expected outcomes.  The instructor uses homework assignments and quizzes to determine if a large majority of students are learning the material and developing the skill sets associated with that course.  If a program-wide problem is encountered (e.g., a large number of students do not have the pre-requisites or have difficulty in mastering a specific skill) the instructor confers with the disciplinary committee members (and the Academic Council, as needed) to implement changes.  These changes may include: changes to the pre-requisites; changes in the text; and changes to the mode of teaching.  An e-mail log is kept of such information from the instructors and distributed to the entire faculty when appropriate.

 

Examination of Course Content and Student Readiness by Upper Level Course Instructors  A second strategy in place is the use of entrance quizzes in our upper-level classes and design/research courses.  This is done to identify students needing help and to identify how the lower-level course material may be reorganized.  Instructors in an upper level administer these tests, usually during the first week of classes.  Their findings are forwarded to the instructor in the lower-level class(es) as well as the entire disciplinary group.  This is done either in the form of an e-mail or in a disciplinary committee meeting.  Disciplinary groups meet once a semester to determine if the expected outcomes are being met and to take corrective actions as needed.

 

Creation of Learning Resources and Refresher Material – Our School has established a Digital Library under the direction of Professor Komerath.  This library contains a vast collection of class notes, homework, computer models/codes, and papers both from within our School and worldwide.  This library contains AE-specific material as well as links to material on mathematics, physics, chemistry, computer science, and life sciences.  Students are encouraged by the instructors to use these resources when the entrance examinations indicate students lack the background.

 

Examination of Student Readiness by Design Faculty and Research Advisors – A third strategy for ensuring the achievement of outcomes is the evaluation of the curriculum content and student readiness by design instructors, and faculty mentors directing student research.  Because our students have the opportunity to work with the design faculty or do research as early as their freshman year, this is a particularly useful approach.  It is not necessary to wait until the senior year capstone design experience to gather this information.  Instructors of the 13xx/23xx/33xx/43xx (design courses) and 29xx/39xx/49xx (undergraduate research courses) provide feedback to the instructors on the material the students should have mastered.  The Academic Council keeps copies of relevant e-mail correspondence between the design faculty, research mentors, and faculty teaching foundation courses, and distributes it to the entire academic faculty for follow-up action.  Actions to be taken are discussed in the faculty meeting and disseminated to our constituencies.

 

Creation of Opportunities for Design experience, Independent Research, and Industry Experience – A further strategy for achieving the outcomes is the creative use of the free electives in our program to provide valuable design experience beyond capstone design (AE1355, AE 2355, AE 3355) and independent study and faculty directed research experience (AE 290x, AE 390x, AE 490x where x indicates the credit hours earned).  This strategy is aimed at achieving outcomes (g), (i), and (j).  Our program is designed so that students can take advantage of co-op opportunities and gain valuable industry/research experience.  We also work closely with industries (Pratt & Whitney, GE), government labs (NSF), and our graduate division to ensure financial support for these activities (in the form of internships) as needed.

 

g.             Assessment Instruments in Use: The School of Aerospace Engineering faculty and students participate in a number of college-wide, institute-wide, and nationwide surveys that are administered by (or facilitated by) our Office of Assessment, headed by Dr. Joseph Hoey.  The Web site <http://www.academic.gatech.edu/assessment/> contains a complete list of these surveys as well as tabulated results.  We use these surveys to benchmark our students against the national student population, to observe and learn from national and institutional trends in education practices, and to find out about the quality of life issues that are important to our students.  We also participate in annual self-assessment of our educational program conducted by the Board of Regents.  This self-assessment study (found at <http://www.ae.gatech.edu/~lsankar/ABET2002>) is evaluated by the College of Engineering, the Institute, and by the Board of Regents of the University of System of Georgia to ensure that our educational programs and practices are consistent with the College, Institute, and University System mission.

 

With the assistance of the Office of Assessment, and in collaboration with the College of Engineering, we conduct the following surveys for the specific purpose of assessing our educational outcomes.

 

Exit and Commencement Surveys – The exit survey is conducted every year by Dr. Joseph Hoey, a resource for our Institute assessment activities, in collaboration with Dr. Yeung, an AE faculty member in charge of School assessment activities.  The survey consists of a questionnaire that the students complete followed by an open-ended discussion.  No faculty members are present.  The discussions are recorded on audiotape with the permission of the students.  The data is distributed, with a transcript of the oral discussions, to the aerospace engineering faculty for follow-up actions.

 

The Office of Career Services also conducts a survey at the commencement where data are collected on starting salaries, number of job offers, student career and educational plans.

 

Alumni Surveys – An alumni survey is conducted once every three years in coordination with the College of Engineering and the Office of Assessment.  A sample alumni survey questionnaire may be found at the AE Web site.  We examine the survey data to determine if the alumni feel they were adequately prepared to carry out their engineering duties and advance in their professional career.  We also examine the data to determine if our alumni pursued graduate studies or continuing education programs after graduation.

 

Co-op Employer Surveys – The Cooperative Division office contacts the co-op employers regarding the performance of the students (every semester for every co-op student at the conclusion of the co-op assignment). Results from this evaluation are shared with the student’s academic advisor and with the School of Aerospace Engineering when corrective action is needed.  The office also surveys the co-op employers every four to five years to compare our students’ preparation (with regard to our expected outcomes) against the employers’ expectations.

 

Student Portfolios – This assessment activity is done to establish if the expected outcomes are being achieved (g)-(j).  We monitor our student participation and success rates in national design competitions, and undergraduate research that leads to externally recognized accomplishments (papers, fellowships, internships). Our faculty members and external visitors also examine and critique student work and their oral presentations. The students are given feed back, usually following the oral presentation, and often in written form that will allow them to improve their work.  This assessment tool also helps us determine if we our graduates are developing skills needed to be successful professionals (educational objective 2; outcomes h-k), and successful human beings with a desire for life-long learning (educational objective 3; outcome k).

 

h.     Assessment Results and Discussion: In this section, some of the significant results and trends that have emerged over the past three years are presented.  We only present the results that are related to the indicators mentioned above.

Senior Exit Surveys – These surveys are conducted every spring.  The surveys for 1997-1999 largely addressed qualitative issues such as the satisfaction with the program, satisfaction with the quality of advisement, and career plans.  The results from these surveys are documented at our Web site but are not included here.  In 2000, with the assistance of the Office of Assessment, these surveys were redesigned to yield more quantitative information related to our educational processes and the expected outcomes.  Oral discussions with the students conducted as part of the surveys are also documented and shared with the faculty.

Additional details of the survey and oral comments by the students are available at the Web site.  It should be noted that that the success criterion is 3.2 (on a scale of 1 to 4).  The graduates rated themselves as having mastered the educational outcomes, as shown below.

 

 

These surveys indicate that the students are satisfied with the technical education they received in our undergraduate program.  The students feel their preparation in mathematics, physical sciences, engineering, testing, design, modern engineering tool usage, and written communication skills are good. 

 

Relative to 1999, students felt better about their written and oral communication skills, although the oral presentation skills fall below the 3.2 threshold discussed earlier.  We have redesigned a number of our courses (e.g., lab courses, capstone design, nationwide design competitions), and continue to modify others to emphasize oral presentation skills, and will continue to monitor student readiness in this area.

 

The students feel that an area that still requires improvement is their training on the societal and environmental impact of their engineering design and engineering solutions.  In order address this concern, the following efforts have been made.  Our introduction to AE course (AE 1350), capstone design sequence (AE 4350, 4351), and the elective design courses already contain lectures on designing for reduced life cycle cost, designing for reduced energy consumption, and designing for reduced environmental contamination.  Increased emphasis is being given to these topics.  We have also increased the frequency of undergraduate elective offerings in areas such as aeroacoustics, noise control, chemically reacting flows (with emphasis on emissions).  Finally, since 1999, the students have had the option of taking a course on environmental science (EAS 1600) to satisfy the science elective requirement.  We will continue to explore other means such as offering undergraduate seminars in this area, in consultation and collaboration with our student organizations (AIAA, Sigma Gamma Tau).

 

Finally, students feel that additional electives are needed in topical areas.  Over the past two years, we have added new electives in CFD, aeroacoustics, and flow diagnostics.  We also offer three new courses on design (AE 2355, 3355, 4355), and numerous independent research (AE 290x, 390x, 490x) courses.  One of the concerns that the students have expressed is that their curriculum is crowded during the first three years, which leaves little room for taking electives.  Our faculty members are aware of this difficulty and will continue to modify and streamline the course offerings and prerequisites to make room for electives early in the program.

 

Student Portfolios Unlike other engineering disciplines, aerospace engineering programs nationwide do not have a P.E. Examination that may be used to benchmark the qualifications of our program graduates relative to others.  Internal assessment of our program by our faculty, valuable as it is in fine-tuning our curriculum and improving the processes, is not sufficient in determining where our program stands relative to other programs around the country.  National Rankings (e.g., U.S. News and World Report where our program was tied for second place with Michigan) use a broad range of measures and do not readily lend themselves to a one-to-one comparison of our program strengths and weaknesses relative to our peers.  For this reason, we use student portfolios of accomplishments as a way of benchmarking our academic program with our peers.  Three measures are used: the percentage of undergraduate students participating in some form of design activity or independent research; the number of entrees to national competitions and research entrees; and the number of entrees that were successful (being placed first, second or third in a competition, being selected for participation in an externally funded research activity).  As stated earlier, the quantitative criterion we use is that one out of every four students will engage in some form of design activity or research activity during their studies at Georgia Tech.

 

Results are collected every spring.  The design courses (AE 1355, 2355, 3355, and 4355) were formally added to our catalog only in the fall of 2000.  Thus, a complete set of data is available for only two years: spring 2001 and spring 2002.  Although this database is consequently small, some useful conclusions may be drawn from the table below. These design activities are beyond the required capstone design activity.

The above table indicates that roughly 15% to 18% of our students are engaged in undergraduate research, design experience over and above the required capstone design, or a research internship experience.  This is below our target participation rate of twenty-five percent.  However, we expect a rapid growth in the number of students participating in research and design competitions, as the large freshman classes of 2000 and 2001 migrate to upper level courses.  In order to further encourage student (and faculty) participation, a number of measures are being implemented.  Allocation of financial and time resources to faculty is being pursued.  Increased allocation of resources to students in the form of research internships (undergraduate research internships, Pratt& Whitney internships, NASA fellowships, etc.) is also being actively pursued.  A Web page featuring undergraduate research is under construction.  We will continue to track the faculty and student participation with the purpose of achieving and exceeding our stated metric of twenty-five percent participation of our students.

 

The above table also indicates that our students are successful in winning national awards, over 50% of the time. The student research proposals are successful nearly 66% of the time. This is very satisfying, given the large number of students and institutions around the country who participate in these activities. We will continue to monitor our students’ performance so that our students may learn from both their successes and failures. Based on this table above, it appears that our educational objectives 2 and 3 are being achieved, although there is clearly room for improvement.

 

Here is a partial list of student performance in national competitions:

 

      Third Place National Winner - 2000/2001 AIAA Team Undergraduate Engine Design Competition, “Extended Range Hypersonic Engine Design: ExRaHyED,” sponsored by AIAA, Washington, D.C.

-                        Second Place National Winner - 1999/2000 AIAA Team Undergraduate Space Competition, “Mars Communications Architecture: Romulus Team,” sponsored by AIAA, Washington, D.C.

      Third Place National Winner -1999/2000 AIAA Team Undergraduate Space Competition, “Mars Communications Architecture: MERLIN Team,” sponsored by AIAA, Washington, D.C.

      First Place National Winner - 1998/1999 AIAA Undergraduate Team Engine Design Competition, “Cygnus X-1: An RBCC Engine for a Single-Stage-to-Orbit Launch Vehicle,” sponsored by AIAA, Washington, DC (joint collaborative design project with Virginia Tech whose team was directed by C. Hall).

      First Place National Winner - 1998 X-PRIZE University Competition, “Polaris: A Suborbital Space Tourism Launcher Concept for Capturing the X-PRIZE,” sponsored by the X-Prize Foundation and MIT, St. Louis MO and Cambridge, MA.

 

Our students also participate in nationally recognized research activities.  For example, Georgia Tech undergraduate research teams have been invited to participate in NASA Reduced Gravity Flight Opportunities for the past three years in a row (1999-2001), and conduct experiments in the reduced gravity environment.  Our Web site <http://www.ae.gatech.edu/~lsankar/ABET2002> contains examples of student design (over and above the capstone design), and undergraduate research.

 

Alumni Survey The School of Aerospace Engineering, in collaboration with the College of Engineering, conducts an alumni survey every three years.  The most recent survey was conducted of the 1994-1997 alumni during the academic year 2000-2001.  Results from this survey are presented on the next two pages.

 

The alumni survey results indicate that our engineers felt that they are well trained in traditional engineering disciplines.  Our alumni also felt that the training they received in these areas exceeded the job expectations in the technical areas listed.  The alumni, however, felt that more needs to be done in the areas of communication skills, ethics, and cultural/ethnic diversity issues.  Our faculty members have discussed how these issues and topics can be addressed in our curriculum without increasing the total number of hours or reducing coverage of equally important technical topics.

 

The 1997 and the 2000 surveys indicated that alumni felt that additional training in the area of engineering from economics and business perspectives is desirable.  To accommodate this, a course on economics (ECON 2100) is now required in our curriculum.  Both the 1997 and 2000 surveys emphasized the importance of ability to function in multi-disciplinary teams and culturally diverse environments.  It is anticipated that the additional team design opportunities that are available in our curriculum (AE 1355/2355/3355/4355) will help our graduates achieve this ability.

 

The alumni surveys provided the following additional information.  Among the 2001 survey respondents, nine out of the thirty-three respondents had participated in co-op programs, eleven had participated in undergraduate research, seven had participated in an internship activity, and seven had also participated in a summer activity/employment related to their major.  This data indicates that our criterion of twenty-five percent student participation in an engineering/design/research activity outside the curriculum is being met.

The alumni were also asked about their graduate/continuing education.  In both the 1997 and the 2000-2001 surveys, the percentage of alumni who participated in professional conferences, continuing education programs, and/or graduate programs was around forty percent.  This data indicates that we are meeting our criterion that one out of three students would pursue graduate studies or a continuing education opportunity.

 

Co-op Employer Survey With the assistance of the Office of Assessment, the School of Aerospace Engineering conducts survey of the co-op employers once every four years.  Data is available for the years 1998 and 2002 at our Web site.  The 1998 survey was qualitative and asked the employers what skill sets they would like to see in their student employees.  This information was used in the 1999 conversion of our program from a quarter-based to a semester-based curriculum, and in our 2001-2002 comprehensive review of our educational objectives and the program outcomes.  The 2002 survey focused on how well our students, from the employers’ perspectives, are meeting the program outcomes.  Representative results of the most recent survey are presented below and the entire survey is available at our Web site.  These results indicate that in most instances the student skill levels increase as they move from the sophomore year through the senior year.  It is also seen that the metric that the employers will rate our students 80% or above (4.0 on a scale of 1 to 5) is being met for the program outcomes.





 

Commencement Surveys The Career Services office at Georgia Tech collects data from all graduates during the commencement ceremonies.  Until recently, institute-wide data was collected.  Beginning in 2001, Career Services also started collecting and tabulating the data by major.  This data is useful for determining if our program is achieving the criterion that at least one out of three of our graduates will pursue graduate studies.

 

During the Spring 2001 survey, thirty-one AE graduates responded.  Out of these, eleven had accepted full-time employment, two were reporting for armed services, eleven had been admitted into graduate programs, and seven were uncertain about (or did not indicate) their career plans.  Based on this information, and the alumni survey results discussed earlier, it appears that our criterion that one out of three of our graduates will pursue graduate studies or a continuing education opportunity is being met.

i.              Closing the Loop: Changes to the Curriculum Implemented as a Result of the Assessment: During the past several years, a number of changes have been made as a result of the assessment processes and results discussed above.

 

Georgia Tech switched from a quarter-based system to a semester-system in 1999.  This presented an opportunity for our faculty to revise the entire curriculum, taking into consideration our constituents’ concerns and suggestions. A number of changes to the curriculum were made as a result.

 

i)      In the quarter-based curriculum, astronautics topics were encapsulated in two or three elective courses.  Under the new curriculum, we embedded these topics across the entire curriculum. As an example, our performance course now covers aircraft performance as well as spacecraft performance.  The flight mechanics and control courses cover both aircraft and spacecraft. The high-speed aerodynamics courses now cover reentry aerodynamics and hypersonic flow.  Every one of our disciplines has incorporated astronautics topics.

 

ii)       We created ten hours of free electives, which may be used in any way the student and the faculty advisor consider appropriate.  Students are encouraged to pursue minors, certificates, independent research, and group design activities over and above the capstone design.

 

iii)      We added new required courses in the areas of material science and engineering, and economics, responding to our alumni’s views on these areas, and recognizing the increased role these fields play in engineering.

 

iv)     Topics on linear algebra were added to the math curriculum.

 

Examination of student portfolios has lead to a concerted effort on the part of our faculty to offer challenging design and research experiences beyond the required courses.  This has resulted in creation of several undergraduate research courses (AE 290x, 390x, 490x), and design courses (AE 1355, 2355, 3355).  As our discussions above show, there has been a significant increase in the number of students participating in such activities, relative to the 1999 baseline.  There has also been a steady increase in the quantity and quality of design entrees, undergraduate research experiences, and national awards, as discussed above. Samples of students work are documented at our Web site.

 

The internal assessment efforts by the faculty members have lead to a number of minor, yet important, adjustments to the curriculum.

 

i)      An examination of the homework assignments in aerodynamics courses indicated that a large majority of the students had difficulties with mathematical concepts such as vector products, divergence, curls, etc.  The mathematics requirement for AE 2020 was increased from Math 1502 (Calculus II) to Math 2401 (Calculus III). When the students with the stricter mathematics requirement were examined during the following year, a measurable improvement was observed.

 

ii)     An examination of the three-dimensional dynamics knowledge of the students by the design faculty (in particular those dealing with spacecraft design) showed that students lack knowledge of three-dimensional rigid body dynamics.  We took this observation into effect while developing our AE 2220 dynamics course. This course has three-dimensional dynamics topics, while its quarter equivalent did not.

 

iii)    Examination of the lower course material by the upper course instructors has lead to a redistribution of material that helped the students better learn the material.  Some of the compressible viscous flow material and the turbulent flow material were redistributed between two of our fluid dynamics courses: AE 2020 and 3021.  We also moved some material in our senior level flight mechanics and controls course (AE4520) to a junior level course (AE 3515) to ensure that students have an adequate knowledge of these topics before entering the capstone design.  Finally, many of our students entering AE learn Java and lack familiarity with MATLAB, a rapid prototyping language often used in AE.  Our Flight Mechanics and Control discipline has assigned a number of assignments and practice sessions to help students with MATLAB when they enter the junior level.

 

Senior Exit surveys show that the students desire more AE electives, particularly in areas such as CAD/CAE, finite element method, computational fluid dynamics, astronautics, and unmanned aerial vehicles.   Several new electives in these areas have been added to the curriculum, as evidenced by the list of elective offerings in the fall of 2001 and spring of 2002.

 

j.        Areas that Need Further Improvement: Our alumni and employer surveys, analysis of our curriculum, and evaluation of our students' participation in design and research all indicate that good progress is being made in achieving our educational objectives.  However, these surveys and studies indicate that there is still opportunity for improvement in the following two areas.


Communication skills
Our alumni and employers frequently point out the importance of oral and written communication skills.  We require LCC 3401, a course on Technical Communication skills, and ME/CE 1770, a course on graphical communication skills.  All our lab courses, and our capstone design courses, require oral presentations.  While these measures have been helpful, we do not yet have in place a systematic effort aimed at assessing student communication skills throughout their career and offering remedial help where needed.  This is an area our faculty will work on during the coming years.  Some of the measures being considered are: use of faculty and teaching assistants from the School of Literature, Communication, and Culture to offer our students training in writing; and expansion of our brown bag lunch seminars to include undergraduate research presentations.

 

Coverage of Ethics and Societal Issues in the Curriculum In many of the AE courses, we extensively cover environmental concerns (lower drag for improved fuel efficiency, reduced acoustic emissions, reduced chemical emissions, use of non-toxic material in design, etc.).  Other areas such as ethics and cultural diversity do not receive a commensurate emphasis in the curriculum.  There is very little room in the curriculum to add courses or topics in this area.  The aerospace engineering faculty are considering establishing an undergraduate seminar series that may be taken for free elective credit, where professionals from industry address these vital issues. Other approaches are also being considered.

 

k.             Challenges Faced: Aerospace engineering, like most fields of engineering, is rapidly expanding.  The number of topics that aerospace engineers need to know is swiftly growing: digital signal processing, statistics, MEMS, CFD, CSD, CAD, CAE, active flow control, avionics, etc.  Yet the total number of credit hours available is clearly limited to 128-136 hours over a four-year period.  Innovative ideas are needed to train our students for tomorrow’s technologies and needs.

 

Our school plans to offer a five-year combined B. S./M. S. program which will allow our graduates to receive a Bachelors’ as well as Masters’ degree after a five-year period.  By taking advantage of the common topics between our Bachelor and the Master degree program, our students will be able to reduce the total number of hours by 6 (2 courses).  These students will be required, as part of their training, to engage in design activities beyond the capstone design and/or participate in research.  This will allow us to meet our target goal that at least one in every five students participates in some form of design or research activity outside the required courses.  At this time, the idea of a combined B. S./M. S. has been presented to our faculty.  A faculty vote is expected in the summer of 2002.
