July 1 Update

bims-lc1We’re entering the mid-summer period where the wind-down from the spring semester collides head-on with the spool-up for the fall semester.  Things are busy on campus.  Here’s a sampling:

  • The first SOAR is over and the second one is next week.  SOARs are events for incoming students to go through orientation and get their class schedules worked out for the fall.  We had 120 students make McMurry their college home a week or so ago.  Over 100 more incoming freshmen are scheduled to be on campus next week.  They are the smart ones, as waiting for the third SOAR or to register at the beginning of the semester means risking closed classes and schedule conflicts.  I mentioned in a comment that roughly 10% of students at the first SOAR signed up for the initial BIMS course.  Looks like it will be a great start for Year Two of BIMS.
  • Summer research is well underway.  Dr. Paul Pyenta has been working with a Welch Summer Research student to clone gfp protein into a plasmid compatible with Bacillus thuringiensis.  They’ve been using the new centrifuge mentioned in a recent post, but found the need to spin 250 ml bottles at a high speed than is possible with the swinging bucket rotor we got with it.  Another centrifuge and modified procedure will have to suffice until we can purchase another rotor more suitable to the speeds required by the original protocol.
  • Dr. Pyenta ordered a new digital gel documentation system today that will allow clear photography of gels for publication and presentation.  This is a valuable piece of equipment for helping students build their biological portfolios – artifacts from their hands-on lab work will be collected and saved to document their proficiency.
  • Dr. Tom Benoit taught Microbiology in Summer 1 and now is working on a proposal for the lab renovation competition McMurry will hold in August.  Science faculty were encouraged to propose innovative spaces for teaching and research for the competition, which will see the winning entry adopted to guide a lab renovation project to take place in Summer 2010.  Two labs and support spaces will be renovated to provide a model of future spaces to be seen in the Finch-Gray Science Center.  BIMS intends to have the best proposal for consideration.
  • Dr. Heidi DiFrancesca has spent time this summer traveling.  No word yet whether she will join her husband Mark on a trip to Japan on behalf of their church.  One additional task Dr. D will accomplish this summer is purchase of the next important pieces of teaching/research equipment:  real-time PCR, Nanodrop spectrophotometer, new tissue culture hoods, and more.
  • Dr. Larry Sharp has been busy overseeing applications to health professions schools – medical and dental, mainly.  He us also teaching both A&P I and II this summer, all while designing the new Pre-Health Professions Seminar series to be taken by our pre-health students.
  • Dr. Gary Wilson has been juggling administrative duties with an overhaul of his microbiology course and some development work for his software package VirtualUnknown(TM) Microbiology.  A new totally online version of the software is in development.
  • BIMS faculty plan to hold a retreat this summer to assess what worked this year and what needs “tweaking” as the BIMS program enters its second year.  One item for discussion is how we can intentionally link courses together through common projects so that we work together in research as our students learn.  We got a great start on that this year, but more can be done.

No doubt, it is a busy summer in Abilene!

Growth Curve Update

by gwilson on Apr.01, 2009, under A Day in the Life..., Projects

dscn2677We’re now 30+ hours into growth curves in BIOL 3410 Microbiology.  Students started at 8:30 am yesterday and made measurements every two hours until 8:30 last night.  We resumed this morning at 8:30 and will take a 36-hour measurement at 8:30 tonight. Our final measurement will be at 8:30 tomorrow morning.

What are my students learning from this?  First, they are learning that science doesn’t occur in convenient 2-3 hour blocks of time.  Second, they are learning that the thought and planning BEFORE beginning your work will help maximize the usefulness of the data obtained.  They are learning that the informal time spent together while collecting data can be very enjoyable.  I learned about my students and they learned something about me as we spent time together through the day.  When I returned from playing basketball, all hot and sweaty, they found I was not a sterile, stuffy professor who has no life.  Finally, I’m hoping their time spent doing this work will teach them a little microbiology.

Our experimental design has eliminated the opportunity to “cook the books” with falsified data.  Their data collection compares bacteria in their own home-made media, while their final product will be a comparison of home-made media for the growth of their own bacteria.  We’ll see how this plays out!
