07270327If you have never been to Mesa Verde, you cannot imagine how majestic and awe-inspiring this world heritage treasure is.  It represents the most amazing collection of artifacts of a lost civilization that one can imagine. 

One of the key elements of the BIMS program is establishing for graduate programs and professional schools our own collection of artifacts to testify to the strengths and abilities of our students.  The BIMS program participates in routine assessment of student and program success.  We want to document proof of effectiveness in providing students with useful and marketable knowledge and skills, and proof that our courses are effective in meeting the program’s goals.  Our flyers for the BIMS program (see BIMS Downloads at the top of this page) outline three lines of evidence (”artifacts”) our students will have of their knowledge and abilities:

  • The biological portfolio of biological products (their personally isolated and identified strains of bacteria, proteins and other products of assays and extractions done in lab, gels and other artifacts of productivity in the lab),
  • The electronic portfolio (posters of their research, reports, digital photographs and micrographs, etc. – artifacts of their analysis and reporting to the scientific community), and
  • Their performance on the BIMS 4000 Junior Exam. 

April 5th marks the day the BIMS 4000 Junior Exam is made available to our junior students.  It consists of basic, intermediate, and advanced questions over the program goals covered in each of the freshman and sophomore courses: 

  • Intro to Scientific Research,
  • Unicellular Organisms,
  • Microbiology,
  • Human Physiology, and
  • Genetics.

Here’s a sampling of three questions students might find as they take this exam…

Means used for preserving foods and increasing their shelf life typically include
A. Acidification to prevent fungal growth
B. Addition of salt or sugar to lower the pH of the foodstuff
C. Removal of available water and addition of acids
D. Pasteurization to sterilize the foodstuff
E. More than one of these

The germ layer from which the skeletal muscles, heart, and skeleton are derived is the
A. Ectoderm
B. Mesoderm
C. Endoderm
D. Notochord

Within the same individual, some genes mutate at a much higher rate than other genes.  This is because
A. Some genes are larger than others providing a greater chance for mutation
B. Some genes have hot spots, which are locations that make them more susceptible to mutation
C. Some genes are larger than others, which prevents DNA polymerase from incorporating the incorrect base during replication
D. A and B
E. B and C

The answer for one of these is A, for one is B, and for one is C.  We’ll let you figure out which is which! :-)   Or, you can find a BIMS major and ask them for a little help.  May your artifact from these three questions match the artifact they will develop as they complete the exam!

July 1 Update

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

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!

New Perspectives on Students – FINALE!

by gwilson on Jun.01, 2009, under Students

cc-ep-school-quicksand-0361Okay, the end, I promise!

So, how can a college science department change its curriculum and pedagogy to reach today’s students in a world where the challenges and issues make this more difficult than ever?  We believe the BIMS program at McMurry provides the template by which an effective program can be built.  I’ve outlined the key elements below.

1. Less is more.   Our overarching approach to our degree has two key ingredients.  First, we believe it is important to know key foundational principles very well, and the rest of what is important will be added along the way.  We  believe emphasizing just-in-time teaching instead of just-in-case teaching.

2. Build the program one brick at a time.  Teach well individual pieces of the curriculum within courses, teach well how the pieces fit together to build the product.  Unique and independent, while also interrelated and inseparable.  Courses do not represent the end of learning on any topic, but instead are new tools to be used for overall learning.  Bricks together are not a house; bricks deliberately placed in mortar based on an overall plan is how you do construction.

3. Engage the unknown.  The unknowable – that which is not found in a textbook – has to be the driving force for engaging student learning.  Why not use knowledge and skills students are acquiring to accomplish something?  We would not know how to teach this major without research-rich teaching.

4. Provide proof of your success.  Our intent is to build a three-pronged portfolio to demonstrate the quality of our graduates.  Each BIMS major will graduate with a digital portfolio, a biological portfolio, and competency testing results.

So, how do these four elements blend together in the BIMS program?  Here’s an overview:

The new BIMS major represents a move by McMurry to provide a new type of Biology graduate whose laboratory skills and experience in molecular biology prepare them for further education or entry into employment in fields requiring such preparation: biotechnology, forensic science, biomedical research, and others.  At the same time, the focus and depth of the degree provide exceptional training in preparation for many graduate and professional programs. The curriculum is centered in contemporary biology and human health. This applied biology training and education is a big step forward in preparing biology graduates with the knowledge and skills expected for biologists in 2023.

 1. As novel as the collection of courses, the true innovation in the BIMS curriculum lies in the teaching philosophy and strategies that will be used. BIMS pedagogy incorporates a new approach to teaching fundamental principles of Biology – “content in context”. Central to the pedagogy is “research-rich” teaching, which gives students investigative assignments in all courses and requires application of skills learned for the purpose of answering interesting research problems. Thus, BIMS courses teach content along with skills in the context of investigation, and reinforce the knowledge and skills through open-ended projects. Students learn to think like scientists and act like scientists by working like scientists.

 

2. Every required BIMS lecture course includes critical reasoning and analysis. Every required BIMS lab includes experimental design and an open-ended research project. In some instances these may employ model systems widely used by top science programs (yeast, Chlamydomonas, bacteria impacting human health, primary and transformed cell lines). There will be plenty of experience in identifying a problem, asking interesting questions, and applying knowledge and skills to find a solution. Required courses will have literature analysis, scientific writing components, and speaking expectations.

 

3. All required BIMS labs take the “content in context” approach. Techniques and content tie together logically, as is currently done in BIOL 3410 Microbiology lab: bacterial strains isolated and identified by students early in the semester become the experimental organisms used for teaching subsequent topics and skills. We see no advantage in using “canned exercises” in our labs to teach stand-alone techniques and concepts unrelated to one another when our more “real-world”, integrated approach can be used instead.

 4. The “content in context” approach will span pairs or series of courses, allowing projects begun in one course to be expanded upon in others. Mutants created in BIOL 3460 Genetics lab can be studied in Molecular & Cell Biology (MCB) Lab. Cell products separated in the MCB lab can be analyzed or modified later in the Advanced Bioscience Lab or the capstone course, for example. Such products and evidentiary artifacts become a “biological portfolio” demonstrating skills proficiency and providing starting materials for the next course taken. In this way, we demonstrate that courses connect with one another, techniques from many courses and disciplines may be needed to solve a research problem, and discoveries are often multi-stage processes taking place over time. This is how science is accomplished, and our students will experience science as it is done.  

 5. It will be important to introduce students to sophisticated equipment and techniques they will encounter when they graduate. Experience and skills that may be transferred to new environments as “newer and better” approaches are developed will be fostered. Emphasis will be placed on hands-on use of such instrumentation to insure all students can “think” and “do”.

 

6. Knowledge and skills proficiency will be a hallmark of this program, with students being required to pass biology content “qualifying” exams in BIMS 4000 before placement in their senior capstone project. These topical exams will be administered in their junior year with opportunities for re-takes until proficiency in subject areas across the spectrum of biological studies is demonstrated. Additionally, we will reinforce knowledge obtained by administering comprehensive finals in all required BIMS courses as a matter of policy.

 

7. We believe a hallmark of any quality program is use of evidence-driven decisions for program improvement. Evidence for assessment can be provided in a number of ways.

 a. Biological Portfolio. The labs central to the BIMS major are focused on generating biological products/artifacts typical of the research lab, whether microbial strains, mutants, proteins, nucleic acids, gels, sequences, or data. These various products can be graded based on their quality, purity, quantity, and/or accuracy, and thus provide a basis for judging successful acquisition of skills and knowledge. The use of the biological portfolio in multiple courses provides confirmation of proficiency of students in skills development, as the quality of products from one course impacts their usefulness in subsequent labs.

 b. Lab Data and Communication Portfolio. Students find themselves responsible for various reports, posters, presentations, and other forms of reporting for their classes, as such artifacts are expected for all courses required for the BIMS major. Besides grades for effectiveness of the communication techniques, these sources can also be used to probe their depth of knowledge and understanding at each course level and thus provide insight into their development. By identifying benchmarks for expectations at sophomore, junior, and senior classifications, the progress toward achieving serviceable skills can be assessed.

 

c. Fundamental Knowledge Assessment. Each student will take BIMS 4000 BIMS Junior Exam during their junior year, with subject tests over foundational biological principles. This functions as the equivalent of diagnostic qualifying exams for graduate students, revealing strengths and weaknesses that must be remedied for students to successfully complete their degree. Students may re-take these exams until they achieve passing scores. Results from these exams will be used to revise and strengthen the curricula of lower level courses (for instance, particularly problematic areas where the pass rates on first or second attempts are below average would emerge and provide ample evidence of the need for taking corrective measures). This exam might also serve as the baseline exam for BIMS students, given in the first year or again in their senior capstone course, along with the MFT in Biology. Such information would be important to assessing “value added”. To help prepare students for these subject tests, BIMS courses will adopt a policy requiring comprehensive exams for all required lecture courses.
