Creating the iLab
Upgrading the Lyman Briggs School (LBS) Biology Laboratories
(Rooms C-4, C-5 Holmes Hall) at Michigan State University
by Douglas Luckie, Assistant Professor of LBS (endorsed by Diane Ebert-May, Director of LBS)
Resources for renovating the infrastructure of teaching laboratories are difficult to accrue currently in any college or university. Yet laboratories built in the 1960s can gain a modern look and have a technology-based learning function for a relatively low cost. In 1999 we proposed to MSU the creation of iLabs - to bring color, technology, research, creativity, and importantly, increased learning of biology by all students in the Lyman Briggs School undergraduate biology program. The project was approved by the College of Natural Sciences and MSU and the iLabs were created in early 2000. You can see what it looks like by viewing photos or watching the iMovie (below). This pilot project is meant to serve as a model for MSU and other institutions for renovating undergraduate science laboratories without mortar and bricks - an inexpensive alternative - the iLab!
Goal: To renovate the biology teaching laboratories by rehabilitating current facilities and introducing new technologies at each research bench (benchtop computers and digital cameras).
Purpose: To give the students better tools with which to study & learn biology. Tools that will allow them to: (i) design new experimental approaches, (ii) perform 'on demand' searches for relevant biological information, (iii) capture and manage data in new ways, (iv) evaluate and communicate their lab reports in new ways. To create a state-of-the-art research space with high tech tools for facilitating better learning in undergraduate biology.
Aim 1: REPAIRS: Repair existing facilities including: electrical outlets, faucets, handles & knobs, and drawers & doors on the cabinets and research benches.
Aim 2: DIGITAL IMAGE CAPTURE: Add digital still photo cameras, Sony Mavicas, and digital video camcorders, Sony Digital8 Camcorders, to facilitate photo-documentation in teaching laboratories.
Aim 3: BENCHTOP COMPUTERS: Add iMacDV computers
to facilitate teaching research and movie making in biology laboratories.

Curriculum, Equipment, and Laboratory Development
The LBS biology undergraduate teaching laboratories (C-4 and C-5) underwent a relatively low-cost renovation. They were repaired and equipped to significantly enhance the technical scope and sophistication of undergraduate laboratories in all areas of inquiry-based biology. Many courses are taught in this facility from freshman-level 'Introductory Organismal Biology' to junior-level 'Advanced Molecular Biology' to senior-level 'Independent Research.' In addition, "Best of Both Worlds" tours (prospective students and their families touring LBS) and LEAP programs (high school students exposed to college science) use this research space.
The two laboratories gained eight iMacDV computers (one
for each lab bench), eight Sony Mavica digital cameras, two Sony 'Digital8'
digital camcorders and the required support equipment and supplies for
the day to day use of these technologies. These cameras and computers will
be used for: internet access, word processing, graphing, spreadsheet programs,
DNA sequence analysis, image capture, movie making/presentation and in
particular, many course-specific packages like population growth simulators
and animal dissection images.
Scientists document their visual findings with photography
and our students should too. The addition of digital cameras will be a
simple yet powerful modernization to the tools currently available in the
teaching labs. We have chosen the Sony Mavica digital camera because it
uses a floppy disk for recording its images. It may seem odd to combine
a floppy dependent camera with a floppy free computer, but we don't want
cameras working with the iMacs. These are devices that will exist in high
enrollment introductory classes where in-lab time is devoted to scientific
experimentation not image manipulation. Thus with a Mavica camera tethered
to each laboratory bench, students can bring their own floppy disks and
photograph as many images as they like in their laboratory exercises (one
floppy disk can hold up to ~50 photos). After completing lab, students
take their floppy disk home to their own computer and, outside of class,
use the images as figures in the creation of traditional research papers
or less-traditional websites to report their findings.
WHAT CAN YOU USE MAVICAS FOR?
With a 'macro' lens and adapter, the camera can photograph
images through any microscope in the laboratory. Thus, for example, in
the organismal biology course (LBS-144), students could take photos of
various dissections and microbiology exercises. They could also capture
images of medaka or sea urchin development over time. In the cell and molecular
biology course (LBS-145), several investigations could benefit from photo-documentation
tools including: carbohydrate diagnostic assays (that yield colored solutions),
paper chromatography, colony growth in bacterial transformation, and agarose
gel electrophoresis. Long-term investigations are also ideal targets for
photo-documentation. Students can capture the progressive stages of hormone-induced
growth of their tobacco plants over 6 weeks. They can also contribute their
best research images to an archive of examples for future classes. As a
result the course will steadily gain more example images and students will
become involved in the process of teaching.
The integration of benchtop computers in the biology laboratory
delivers instructional tools, reference sources, and data acquisition devices
directly to the student scientist. Traditional PCs are large multicomponent
systems that dominate too much bench space in the wet lab. Apple iMacDV
computers are small, light, fast, easy to use and wireless. If you'd like
to do wireless networking and make movies, they are significantly less
expensive than PC systems ($1299 vs $2999+). Digital video facilities built
into iMac DV computers make generating short instructional quicktime movies
simple and easy. We intend movie making to be a part of the upper-level
undergraduate classes with smaller enrollments. This is where the Sony
Digital8 camcorders come into play. When you're not making movies,
reference sources can also be quite useful when they are right at the investigator's
fingertips. Internet databases, vivid images, and special software packages
can assist the student as they do investigations in the course laboratories.
Data acquisition devices are also made possible by benchtop computers.
USB/firewire-based hand-held spectrophotometers and various sensors can
record and display data directly on the computer.
WHAT CAN YOU USE BENCHTOP COMPUTERS FOR?
Current laboratory investigations in LBS biology courses
are being enhanced by benchtop computers. Benchtop computers are delivering
movies, animations, and slide imagery directly to the undergraduate investigator
at the wet bench. For example: the organismal course (LBS-144) uses the
computers to deliver genetics/population simulation software, as well as,
to allow students to view the development of medaka fish from egg to adult.
The cell and molecular course (LBS-145) uses the benchtop computers for
viewing 3-D structures of the molecules of the week. In addition, "DNA
Stream" exercises are enhanced by giving students access to DNA sequence
analysis software (DNA Strider) at the bench. Computers can be a resource
to obtain protocols for experiments, to deliver quizzes or summary sheets,
and to view CD-ROM animations of biological mechanisms (Bio-Sci Explorer).
Since digital camcorders are available to the student scientist THEY can
create movies of their research findings and edit the video on the iMacs.
Do you think a student might enjoy creating a webpage instead of a written
paper? How about one with both color still images (mavicas) and a short
movie showing the experiment or animal they were studying. See what
we are doing in a senior seminar course in Fall 2000 (http://surf.to/492).
In addition the instructor can make movies to be delivered to orient the
students. As instructional tools, these movies could be used for orientation,
safety review or to introduce the topics of this week's lab.
NOT YET CONVINCED?
The availability of new tools may have benefits yet unforeseen
by this proposal. When computer projection equipment was first introduced
into the Lyman Briggs lecture hall (C-106 Holmes Hall), faculty did not
at first see any great use for it. Now numerous lectures depend
on it. Given new tools in the laboratory, faculty will have the opportunity
to create new exercises that may not have been previously possible. These
courses also have several opportunities where the students pursue independent
investigations, it is likely your students may develop new uses for the
technology that you have not yet considered.
