You are probably using either
or Opera to view these materials.
Those are the most popular web browsers.
To use all the features of SticiGui©, you need an up-to-date browser that
must also accept cookies from the originating server.
For a variety of reasons, I strongly recommend that you use Firefox and that you
not use Internet Explorer.
Recent versions of Chrome, Safari and Opera also work—mostly.
The materials have been tested most thoroughly with Firefox.
is a piece of text you can "click" to see another document. You place
the cursor over the link, then push the mouse button (left mouse button on a PC compatible
computer) to "follow" the link.
Links in these materials are generally in blue type.
Clicking a link can either replace the document in one of the frames
you are viewing (not always the frame that has the link), or open a new
window that displays the new document.
If you have not changed the default settings in your browser, links to the
glossary will be in green type; those take you to the right place in the
glossary in the bottom frame, so that you don't lose your place in the
book when you look up a term.
Links to other materials are in blue type; those typically replace the contents
of the frame you are reading.
You should familiarize yourself with how
your browser works to learn to navigate among windows.
On the right side of the browser
window, you should see a scroll bar. If there is a scrollbar, that means there is more to
see—drag the slider down to see more of the text.
On some computers, there is a
"page down" button you can click to see the next screenful of text.
In the assignments, the navigation buttons
are suppressed to leave more room on the screen for text and graphics.
You can still get a "pop-up menu" that will allow you to go back to the
How you get the menu depends on the browser and the operating system.
In Microsoft Windows, you get the pop-up menu by right-clicking in the open browser window.
Most browsers have the ability to search within a document to find a word
or phrase within a page.
You might find that feature useful to search for a word in the glossary
or a chapter of the text.
There are graphical
data analysis and visualization tools
throughout the text and assignments.
Every chapter has
exercises to check your understanding.
I strongly recommend that you do all of them. Most
of the exercises call for an answer in a box.
After you type in your answer, strike the
"return" or "enter" key.
The symbol next to the question will change
from a question mark
a green check
(if your answer is right) or to a red X
(if your answer is
Multiple-choice questions automatically show the green check or red X when you
select an answer.
Multiple-multiple-choice questions ("select all that apply")
are followed by a button you can click to check your answer.
Clicking the mark after the question
(the question mark, check, or X) will expand a box containing the correct answer, if you have
already attempted the problem.
You can answer each question as many times as you like, or see the correct answer.
More detailed solutions to some of the exercises are available too; there is a link to the
detailed answers after those questions.
Your answers to the exercises in the text are not
recorded, and the exercises do not contribute to your grade.
Many of the problems are
generated randomly—reloading or revisiting the page will give you a new set of
problems, so you can get unlimited practice.
Most of the chapters have a corresponding
assignment covering the
material in the chapter.
The assignments are graded by a computer, and may contribute to
your grade (your instructor will tell you).
Be sure to click the button labeled
"Submit for Grading" after you answer the questions in each assignment.
After the due date of the problem
set, you can see your score
by filling out a form.
You can also see the solutions after the due date by returning
to the assignment.
