Nutrition 111AV – Introduction to Nutrition and Metabolism
Computer-Based Teaching Tutorial
Nutrition 111AV is a computer-based teaching (CBT) course. That is, there is no
in-class lecture. The primary course content is contained on 8 separate files (each
file is one Chapter) that you will download onto the hard drive of your computer
from the course web site. The CBT is supplemented with the book by Grosvenor
and Smolin “Nutrition: From Science to Life”.
PC Compatible Computer with Windows 98, Windows ME, Windows NT 4.0,
Windows 2000, and Windows XP
Screen Size: 800 x 600 SVGA
RAM: 64 MB minimum; at least 128 MB preferred.
Disk Space: 20MB of free disk space, and CD-ROM drive (optional) or Zip Drive
Each Chapter is approximately 15MB and there are 8 chapters for a total of
120MB. Only one chapter needs to be on the hard disk at a time, although having
enough space for all 8 is preferred. DO NOT ATTEMPT TO RUN THE PROGRAM
FROM A CD OR DRIVE OTHER THAN THE HARD DISK. ALWAYS
DOWNLOAD THE CHAPTER FILES TO YOUR HARD DISK. THE PROGRAM
PERFORMANCE WILL SIGNIFICANTLY DECLINE IF RUN ON A DISK OTHER
THAN THE HARD DISK.
If you plan to use a computer in one of the computer labs on campus, you
will need to provide your own headphones for sound. These computers do
not have speakers and headphones are not available in the labs.
LEARNING APPROACH AND COURSE STRUCTURE.
The learning approach to this on-line course uses several teaching mediums
simultaneously to enhance the learning experience. On each page, you are
presented with material that will require the use of sight (animation), reading
(text), sound (voice), and computer navigation (linking to various sites that are
external to the primary presentation window). This approach has resulted in a
course structure that has four levels of learning.
Level 1 – Presentation Window and Text
The primary teaching medium is the animated presentation window that is
accompanied by visual and audio text (see below). The student is responsible for
understanding the concepts and all material presented here. Knowledge
expectations are given on the Introduction Page for each Chapter.
Level 2 – Expanded Core Material -- THE APPLE CORE ICON
From time to time, the student will be asked to navigate to material that expands
on a concept, but does not fit easily into the format of the presentation window.
Such material is REQUIRED READING and can be accessed by clicking on the
APPLE CORE ICON appearing in the presentation window.
Level 3 – Review or Extended Material -- THE EINSTEIN ICON
Any student with upper division standing, i.e., a junior or senior, will be successful
in this course without having previous courses in basic science. However, some
concepts may require a rudimentary understanding of biochemical and/or
physiological processes. The course contains several review or introductory pages
discussing basic science concepts such as chemical bonding, the action of
enzymes, body composition methods, etc. Some of these pages may also contain
information for students who wish to know more about a topic than that which is
within the scope of the course. The Review or Extended Material pages can be
accessed by clicking on the cartoon picture of ALBERT EINSTEIN appearing in the
presentation window. Any material linked to the EINSTEIN ICON is NOT
Level 4 - Text Book
The book by Grosvenor and Smolin entitled “Nutrition: From Science to Life” is
required for this course. The required readings, found on the Introduction Page
for the Chapter, will significantly aid in your understanding the material presented
through CBT. As with the material in the presentation window, you are expected
to understand the basic concepts.
Suggested Study Pattern
Although each student may find a study pattern that is best for him or her, we
found that the following study pattern is optimal.
1. Run the program from beginning to end without interruption, including
taking all quizzes. This will provide the student will a “feel” for the concepts
in the chapters.
2. Read the required reading from the book (found on the last page of the
3. Re-run the program and slow down by replaying sections where necessary in
order to have a complete understanding of the material. Be sure to read all
the material linked to the Apple Core Icons and any review material
(EINSTEIN ICON) you feel unsure about.
A Note About Biochemical and Physiological Precision and Accuracy.
The purpose of this course is to introduce you to the concepts of nutrition from the
perspective of metabolism. As such, basic biochemistry and physiology is used to
demonstrate nutritional models. It would be impossible, however, to provide an
in-depth discussion of all biochemical and physiology mechanisms for each unit
presented. Therefore, you may find that we have taken some “liberties” in the
precision and accuracy of biochemical and physiological pathways in order to
emphasize the important concepts of nutrition. If, at any time, you are unsure or
confused about a particular biochemical or physiological pathway, please do not
hesitate to e-mail me with a question or ask the question during the chat room
In addition, the entire presentation including most of the graphics, text, and
navigation were programmed, written, and designed by one person – Dr.
McDonald. I do not have the resources of a Microsoft or Sony to ensure a quality
that is perfect. That is, there will be mistakes in spelling, misalignment of graphic,
less than perfect sound quality, and other problems that we have not fixed. If you
find problems, please let me know and we will do all we can to fix them. Also,
please forgive the color scheme of the presentation. I am color bind and have a
difficult time matching colors. I am fortunate to have an assistant that has
agreed to start coordinating the colors better. This will change throughout the
Downloading, Unzipping, and Running the Course Modules.
Each module for the course consists of an executable file (ends in .exe) and a
folder of library files called “Xtras”. These components are packaged together in
one zip file for each module. You can use any program you want to unzip the files
such as Winzip or Aladdin Stuff-it Expander. Below are instructions on how to
unzip the files with Winzip. As stated in the syllabus, we cannot provide you with
more assistances than that provided here. If you have trouble, please contact the
assistants at IT Express.
Winzip. WinZip is a program that is used to create and extract file that have been
compressed. The compressed files “lives” in a format called archives. Archives are
files that contain other files, and Zip files are the most common archive format.
Typically, the files in an archive are compressed. Compressed files are files that
are created in order to make transferring files between computers easier. WinZip
uses the term “Add” to mean “compress files and add them to an archive”.
“Extract” means “decompress files in an archive, creating separate files on a disk”.
Some people use the verbs “zip” or “pack” instead of Add, and “unzip” or “unpack”
instead of “extract”. You will be extracting files from the .zip file you download.
Step 1: Install Winzip. Most new (1-2 years old) come with Winzip installed on
the hard disk. However, if you do not have Winzip, it can be downloaded for free
at the following site:
Step 2: Download a module. All course modules will be available at the above
web site and on the date given in the syllabus. Click on one of the links (course
chapter) and when prompted save the file somewhere where you will be able to
find it later (I recommend you save it to the Desktop). Remember, you are
downloading a zip file that contains the course program. Therefore, when you are
ready to unzip it, look for the name of the chapter associated with a Winzip Icon.
Step 3: Open the zip file in Winzip. Once you have downloaded one of the
course modules, you must extract the files from the zip file. The first step is to
open an archive. If Winzip is your default application to open zip files, you can
simply double click on your zip file to open it with Winzip. You can also open the
archive by doing this: Open Winzip and then use the Open toolbar button or select
Open Archive from the WinZip File pull-down menu to activate the standard Open
Archive dialog box. Then, select the archive you want to open in the Open Archive
dialog box. This dialog box works just like the Open dialog boxes in other
applications: just select the file you want to open from the list of files.
Step 4: Unpack the zip file to extract the files it contains.
Once you have opened the .zip file, you can extract the files it contains. The files
in an archive are listed in the list box in the main WinZip window. When you
extract a file, WinZip decompresses it and places it in the folder of your choice.
You can restore whole folders and retain the structure of any sub-folders.
To extract the files, select Extract from the Actions pull-down menu or click the
Extract toolbar button. WinZip lets you choose the folder where you'd like to
place the extracted files. MAKE SURE YOU NOTE THE FOLDER YOU CHOOSE
HERE SO THAT YOU CAN FIND THE EXTRACTED FILES LATER. WE
RECOMMEND THAT YOU SELECT THE DESKTOP.
Step 5: Run the executable file for the module.
Once you have unpacked the zip file, a folder will be created in the location you
selected called by the name of the module, such as “Carbohydrates.” Double click
on this folder to open it. Inside will be one executable file (file that ends in .exe)
and a folder called “Xtras.” Double click on the executable file (example:
carbohydrates.exe) to begin the module
**** THE FOLDER CALLED “XTRAS” MUST BE IN ****
**** THE SAME LOCATION (FOLDER) AS THE ****
**** EXECUTABLE FILE ****
The window on your computer screen that contains the course material is called
the Presentation Window. There are several features to the presentation window
that are common to all pages in the class.
Pull-Down Menus. In the top left corner within the gray tool bar strip are two
pull-down menus: File and Word Definitions for This Page. The File pull-down
menu contains the option “Quit”. Clicking the “Quit” option will cause you to exit
the program and return you to computer desktop. It will save your current
location so that you will re-start where you finished. The Word Definition for This
Page pull-down menu contains the definition of words used in the TEXT BOX (see
below). Red-colored words within the TEXT BOX indicate that they are defined in
the Word Definition for This Page pull-down menu. To use either the File or Word
Definition for This Page pull-down menus, click on either and then select and click
on the option in the pull-down menu.
Chapter, Unit, and Page Name. Just below the Pull-Down Menus are the
CHAPTER NAME (WHITE), UNIT NAME (WHITE), PAGE TITLE (BLUE), PAGE
NUMBER AND TOTAL PAGES (BLUE) The course is organized much like a book –
the CHAPTERS are broad categories (Lipids, Carbohydrates, etc.) that are broken
into smaller UNITS (Lipid Digestion, Lipid Metabolism, etc). The PAGE TITLE gives
a brief description of the contents on the current page. The PAGE NUMBER and
TOTAL PAGES provide the current page number and the total page numbers for
that UNIT. Be sure to use these designations when asking questions.
Global Navigation Buttons. Under the Chapter, Unit, and Page Name are
navigation buttons that, when selected, will take the user to the Chapter’s Table of
Contents or a graphic describing the anatomy of an animal cell. Additional buttons
will be added throughout the course.
Pause and Continue Button. To the right of the CHAPTER, UNIT, AND PAGES is
the PAUSE button. Clicking on this button will pause the presentation. Click on
the CONTINUE button to continue the presentation.
A note concerning a problem with this feature. When you click on the PAUSE
button, the animation and voice will stop. Clicking the continue button will start
both again. However, the synchronicity of voice, text, and animation will be lost.
As hard as we have tried, we cannot seem to fix this problem. We will keep
trying, however. If the lack of synchronicity bothers you, just hit the Replay
Button (see below) to start over.
Unit Navigation Buttons. To the right of the PAUSE button are the UNIT
NAVIGATION buttons. These buttons allow the user to move Forward one page,
Backward one page, Repeat the current page, and Search the current UNIT for a
specific word or phrase. The Forward button will not activate when you are on the
last page of the UNIT. The backward button will not activate when the student is
on the first page of the unit.
Text Box. In the lower left hand corner of the PRESENTATION WINDOW is the
TEXT BOX. The TEXT BOX contains the text that accompanies the presentation.
The text in the TEXT BOX is read aloud by Jessica Coppola, Associate Developer,
