[sound]. This video contains information on how to
set up your ALEKS account for this Math 1A Pre-calculus course.
ALEKS stands for Assesment, and Learning in Knowledge Spaces.
It is an online addaptive learning program that uses artificial intelligence to
precisely identify and deliver personalized instruction on the exact
topics each student is most ready to learn.
To begin the ALEKS program, open up a web browser on a computer connected to the
Internet and go to this URL up here. www.aleks.com and then click on this link
here on the upper left that says sign up now
And since you will be using ALEKS with a class, we'll be focusing on this left hand
box here. Now your professor should have provided
you with a course code which you'll enter in here
And then click continue And now it will ask you to confirm your
enrollment information. Yes, I'm in Math 1A, pre-calculus, with
professor Anteater, at UCI And now click on continue,
Now you're asked for your twenty digit access code, which you can either purchase
from the bookstore or ALEKS directly by clicking on this link here that says
purchase an access code online. So let's enter in our access code
And click continue. Now entering your student information here
Peter Anteater
And now enter in your email. Panteater@uci.edu
And entering a password the six letters or digits minimum
Confirm that password And then entering your student ID
And then scroll down and read the [inaudible] user agreement.
Once you've read it, click on this box here.
That you have read and that you agreed to the terms of the ALEKS users agreement and
then click continue. And now we'll give you your log in, which
you will use with the password you entered in the last step every time you log into
ALEKS. Now click continue
And [inaudible] will look for a plug in on your computer and install it if needed.
Here we didn't need to install it, but if the plug in is installed you may need to
restart your browser and then log back in with your login and password.
Now you will learn some of the basic ALEKS answers input tools known collectively as
the Answer Editor. So using your keyboard, type in the number
fourteen And now it's asking you to hit this clear
button, which notice clears that number fourteen.
And now it's asking to click undo. Which notice, undid the last action, of
clearing that number fourteen. Alright, so let's click on next, to look
at the next exercise. Let's learn how to enter in a fraction.
So let's click this fraction button here And now the numerator will type into
And then we'll click in the denominator and type in three
And we've entered in the fraction 2/3rds. So let's click on Next to go to the next
exercise. Now let's learn how to enter an expression
with parenthesis. So let's click here.
And with our keyboard we will enter in our left parentheses x+4.
Right parenthesis And then click on the exponent button
And type into And then click over here in this blue
circle to get out of the exponent And then using the keyboard type in
+seven. Click on this blue circle and hold until
you get to this blue circle Release
Now click on this fraction button Which put everything that we had
highlighted in the numerator of this fraction.
And now type in three to the denominator And we've entered in this expression.
So let's click on Next to go to the next exercise.
Now, let's learn how to plot a point and draw a line.
Let's click on the pencil button. Come over here
And plot this point. Then, click on the ruler button.
Move your mouse into this blue circle, click here
And now grab the pencil icon again And move your mouse over here.
Draw to here, draw to here And we've drawn a line.
So let's click on next And now we look at the ALEKS calculator
But it should be pointed out that not every question in ALEKS has a calculator
active. It is only active when ALEKS feels it is
needed for a certain problem. If it is not active in ALEKS, do not use
your own calculator. So let's click on okay.
And then we'll come up here and click on the calculator.
We'll click on this blue box. We'll type in the number 31.
And then we'll click on the addition button
And then we'll type here nine And then click on the Equals button
And so on. So it functions just like a normal
calculator. All right
Let's click on next. Now, at anytime during assessment or
learning if you ever need a help, there is this help button up here on the top that
you can click And over here on the right there is a link
to an ALEKS user guide which you can always read
And then over here on the left we see this link, all topics for pre-calculus.
So let's click on that And this will give you an extensive list
of topics and tools that you might encounter in the answer editor
And when you are done reading what you were looking for you can click on done
down here And also, if there's a new tool in a
question that you've never seen before, there's this quick help.
That you can click on to learn how to use that tool.
Let's click on next, Now that you are registered and have
learned about the, and editor, you'll be given what is called your initial
assessment. This is basically the heart and soul of
ALEKS, as it will determine your starting point, or baseline for your learning,
which is called your knowledge state. Now during this initial assessment, you'll
be asked between 25 to 35 questions and the powerful assessment engine within ALEKS
will be capable of pinpointing your knowledge state very precisely.
That is a system will know what you know, what you don't know, and what you are
capable of learning next. And what you don't know, and what someone
else in the class doesn't know, will be different.
But that's okay, ALEKS will fill your learning gaps when you get in to the
learning mode after your initial assessment.
Now during this initial assessment you should have a pencil and paper handy.
Don't be anxious or nervous, just do your best.
Okay, so let's get started. So the first question here, you're asking
to graph the line, X + 2Y is equal to negative two.
Well, when x is equal to zero, for example, this equation simplifies to 2y is
equal to negative two, or y is equal to negative one, which means the point 0, -1 lies on
our graph. So let's come over here and grab our
pencil. Go to x is equal to zero; y is equal to
negative one, and draw a point. And now, looking back up here
When Y is equal to zero, X is equal to negative two.
Which means the point -2, 0 also lies on our graph.
Now we could take our pen tool and plot the point x=-2, y=0, but let's look at
this other feature over here. If we click here, then we can actually
enter in the ordered pair here. So x=-2, y=0 and click on plot point and
it will plot it for us. All right, now let's grab our ruler.
Click on one point. Click on the other.
Grab our pencil again, and draw our line. And then click on next to submit your
answer. Now notice we were not told whether we
were right or wrong here. And you will not be told until you get a
report at the end of the assessment. Alright let's scroll down here.
Now notice this button next to this. Now, if, at any time, during your initial
assessment, you honestly do not know how to answer a certain question, or you've
never learned that topic before, then click on I don't know.
But whatever you do, do not just click it because you want to get through the test
quicker. This will make more, many, many, many more
hours of unnecessary work throughout the quarter.
Just do your best, and try to answer any question that you think you have a shot at
answering correctly. So let's say Peter really doesn't know how
to answer this question. He can click on I don't know.
All right, in this problem we do know how to answer.
This is an application of the Pythagorean Theorem.
So the hypotenuse squared or X squared is equal to the sum of the squares of these
two sides. So X then would be the square root of 144
plus 100, or the square root of 244. Now notice the instructions here.
They say to round to your nearest tenth. And then notice the calculator is active.
So let's use it. So we come over here
And we type in the square root of 244, click on the equal's button
And so rounding this to the nearest tenth we'll get 15.6 so let's enter that answer
here. You can close our calculator.
So entering 15.6 And click on Next
Alright and for this one, by properties of rational exponents.
We can take the fifth root of 32 first, which is two, and then cube that answer,
which is eight. So our answer here would be eight.
Now for demonstration purposes let's just skip to the end of the assessment.
Alright so this is a, the end of assessment.
The function f is defined by f of x is equal to x squared minus x, and they want
Peter to find f of 2x. So we plug 2x in whenever we seen an X so
2x squared is four. X, press the Exponent button, squared, and
then minus. Plugging in 2x again we have 2x, and then
we click on Next. And the assessment is complete.
So let's click on next to see what ALEKS learned about Peter Anteater.
Now this is what is called Peter Anteater's ALEKS Pie.
In ALEKS, a student's knowledge is represented by these multicolored pie
charts, and this pie chart is divided into four slices here.
Up here the red slice contains topics in conics sections.
This purple slice contains topics in polynomials and rational functions.
The yellow slice contains topics in functions and graphs.
And the blue slice contains topics in algebra and geometry review.
And the 113 topics that ALEKS determined Peter knows are split up into these four
slices. All right, let'*** continue here.
The dark part of each slice corresponds to the topics Peter knows.
And the lighter part corresponds to the topics Peter will learn.
His goal is to fill his pie, that is to make each slice dark.
So this is a powerful motivator because he wants to feel the entire pie by making all
the slices dark. All right
Let's click on continue here. Now Peter's goal here is to learn all the
topics in this course. And the ALEKS pie is very user friendly
when it comes to navigating through the topics within each slice.
So let's say Peter wants to work over here in Algebra and Geometry review. He simply
hovers over that slice, and ALEKS gives him access to all the topics he is ready to
learn. So let's say Peter wants to work on
rational and irrational numbers. He would click here.
And ALEKS will give him a problem on classifying rational and irrational
numbers. So this first number, the square root of
nineteen, is irrational. The square root of nine, that square root
might throw him But the square root of nine is three and
three is a rational number. Negative seventeen over two is rational.
This repeating decimal's rational. This number is irrational.
And then Peter clicks on Next to submit his answer.
And look up here, it tells him right away he got that question right.
And if he answers it correctly without help one more time, ALEKS will add this
problem to his pie. So he clicks on practice down here.
And again, he's gonna classify these numbers.
This is irrational, this is rational. This is rational, this is irrational and
this is rational, and then Peter would submit his answer by clicking Next.
And ALEKS tells him that he has learned this topic.
So scrolling down here there's this button for more practice if he feels like he wants to
practice more. Or he can click on Done to return to his
pie. So let's click on Done here.
And notice that his number of topics increased from 113 to 114 because that
topics was just added to his pie. Now you might be wondering what these
dotted white lines are here in the pie. These signify or encompass the topics that
are in the current intermediate objective. In this Math 1A class there are two
intermediate objectives, and basically what that means is that the course content
is split into two sections. The first part of the course which
corresponds to topics that will be on your midterm.
And then the second part of the course And both of the objectives together
correspond to the topic you'll see on your final.
And notice down here ALEKS tells you how many topics that'll need to be mastered
before the due date of the objective. So let's go back to our pie, and choose a
different topic. Let's say Peter wants to work on
polynomials and rational functions. Again, he hovers over that slice, and ALEKS
gives him access to the topics he's ready to learn.
So let's say he wants to work on discriminant of a quadratic equation.
You click here. And let's say Peter really doesn't know
what the discriminant is. He can click on this explanation button
here and Alex has a full detailed explanation
on what a discriminant is, as well as applying it to the current problem.
It also has additional resources over here.
PDF's to the book, video lectures, etc. And let's say Peter doesn't know what a
quadratic equation is for example. He can click on this link here
and it will take him to a dictionary page which gives him information on a quadratic
equation And after he's done reading and he gets
the information that he's looking for, you can close the window,
which brings him back to the problem at hand.
So, let say Peter still doesn't understand or he doesn't feel like working on this
problem anymore. At any time he can come up here to my pie
and choose a different topic. So maybe he'll come over to this slice,
functions and graphs or maybe he wants to go back to the algebra and geometry
review, and so on. Now ALEKS will periodically reassess you,
to confirm your retention of the topics you have studied.
These are called automatic or progress assessments
and are given based on your rate of progress in ALEKS, and the amount of time
working in ALEKS. Now, it should be pointed out, though,
that although you demonstrate mastery of a certain topic in your learning, ALEKS may
expect you to demonstrate continued mastery of that topic in subsequent
assessments. And if you seem to need review, ALEKS will
subtract that topic and possibly other prerequisite topics from your pie, making
them available for a selection again in learning.
Therefore, always try to do your best on assessments.
Alright there are a few more things to point out here.
If you look up here on the top right, there' a button that says report.
And if we click here, it gives you a full report on your
knowledge. It shows your pie,
what topics you can do, what topics you're ready to learn, as well
as your history, your assessment performance,
the percent of the current objective that you have satisfied.
And then if you go back up to the top here, there's a tab that says time and
topic. And this gives you the time that is spent
in ALEKS, as well as the topics that were attempted and the topics that were
mastered. And when you're done looking at the
report, you click on Done here. And also up here there's a tab that says
Calendar And if you click here it will give you the
dates of your midterms, links to them, the due dates of your objectives,
your final exam and so on. And at any time if you want to contact
ALEKS customer support, you can click on your inbox up here.
And you can compose a message and when you click on these two icons, you can choose
to send ALEKS customer support and your professor an email.
And ALEKS has a lot of cool features like this and wants you to start browsing
around the website. You familiarize yourself with them.
And for all other information on this course, please see the course website.
It has full details on all aspects of the course.
Have fun learning. [sound].
