Beginning April 18, our meetings will be held in the Tallan Cellar Restaurant, Two Union Square, Chattanooga, TN  37402.
 
NEXT MEETING (noon)_______________________________________________________
Location:  Terrace Room in the Sheraton Read House Hotel, 827 Broad Street, Chattanooga, TN  37402
 
April 11:  "Electron Microscopes Can Characterize Nanomaterials at Sub-Angstrom Resolution"  Dr. Larry Allard, ORNL

Dr. Allard is the principal technical designer of Oak Ridge National Laboratory's new Advanced Microscopy Laboratory, a facility housing the most advanced and sensitive modern electron beam instruments.  He began using electron microscopes in the 1960's as he studied microstructures of stainless steel and nickel-based superalloys to characterize creep-rupture failure mechanisms at the University of Michigan.  Dr. Allard is now a Distinguished Research Staff Member in DOE's High Temperature Materials Laboratory, a National User Facility located at ORNL.  He will tell us about his current research of nanophase and nanostructured materials and instruments developments involving electron holography as he describes the special facility at ORNL that has been built to house three and soon four aberration-corrected electron microscopes.
 
Invocation:  Jack Wagner
 
Menu: Not available, yet.  Please call the Sheraton Read House at 423-266-4121 if you need to know the menu.  A plate lunch will be served for $11.
 
OUR PREVIOUS MEETING ____________________________________________________
 
 
April 4:  "Comparison of Traditional and Distance Education Delivery Outcomes for an Engineering Statics Course" - Dr. Wes Hines, UT Knoxville
 
Our joint meeting with the American Society of Engineering Educators (ASEE) Southeast Section Conference introduced us to this award-winning paper by Kurt Gramoll, Wes Hines and Mary Kocak.  Dr. Hines told us that one in five students who graduate with an engineering degree transfer to a four year college in their junior year from a smaller two-year community college.  When they transfer to a four year college, they can complete a business degree in two additional years, but often it takes three additional years to complete an engineering degree.  An option that can be used to boost their core skills and make an engineering degree a possibility in two rather than three additional years is distance learning modules. 
 
Their experiment was funded by a grant from the National Science Foundation (NSF).  Its main objective was to prove that distance learning technology can be a successful means of improving the rate and ease of transfer from a community college to an engineering program at a four year institution.  The modules in the online course included 1) an e-textbook with online Statics problem examples, 2) online lectures, 3) online "coaching" in which the students could ask questions where other students might respond but the professor moderated and ultimately provided answers, and 4) online exams.  In the student-posed question module, the professor responded with answers usually within six hours and always within 12 hours providing timely feedback.
 
The same material was taught and the same tests were given as the traditional classroom course to compare student understanding and comprehension of a course in Statics.  The students were allowed to select their preferred way of taking the Statics course and the distance learners scored slightly better than the on-campus learners.  They are now checking the grade point averages of the students involved in this study to determine if those who selected the distance learning option had better scores before entering these classes that were compared. 
 
The conclusions in this presentation showed that distance learning option prepares students as well as the on-campus course, that 70% of the students taking the online course would recommend it to others, and that the students greatly appreciated the flexibility of this alternative
