For the Instructor

What is an instructor's account

An instructor's account is a free-of-charge user account giving full range of use to the MathLynx functionality available for instructors.   This includes the ability to create classes, edit their contents and who has access, give assignments to students and track their progress, view content as a student in your own classes, examine class records (including those for individual students or single assignments), and obtain spreadsheet-viewable course data.

How to get an instructor's account

To obtain an instructor's account with MathLynx, first create an account (click here).   You will then need to send a request from a professional email address to mathlynx, stating your position, department and institution.   You will need to include a link to the departmental website indicating your affiliation.   We will respond shortly with an email notice that your account has been upgraded to that of an instructor.

You will automatically be given a student account with the same username with "stud" appended (thus instructor id = "ProfXYZ" gets student account id = "ProfXYZstud") with the same password, so that by logging in as a student you can see at any time what your students will be seeing.

How to create a class

To create a class, select Reports under the INSTRUCTOR tab in the header menus.   You will be redirected to a page on which you must select Course Creation & Maintenance Report, as indicated.


This takes you to the following page.


You can now enter a course name and click "CREATE COURSE", as shown below.


The course will now exist with you as instructor, and you should be able to see this in the drop-down selection tool at the Course Creation & Maintenance Report page:


The only courses you should see here are courses for which you are an instructor.   Your student id will automatically be enrolled as student in the class so that you can at any time review the course contents from the perspective of a student.

How to create/alter course content

To create or alter course content, at Course Creation & Maintenance Report select the desired course from the drop-down selection tool.   The only courses you should see here are courses for which you are an instructor.   At this point the buttons on the page will be enabled and you will be able to click on the "EDIT PAGES OF THIS COURSE" button.


You will now be able to add/remove pages to/from your course, control the order in which students of your course will see them, and if you wish to put trial or time constraints on evaluations then you do this here.   For example, in the following images we add the page "precalc_geom_eval_perp" to our Sample Course 1 by copying this local address into the text region at bottom of the "EDIT PAGES OF THIS COURSE" page and then clicking "ADD PAGE TO THIS COURSE".   Note that Sample Course 1 already contains one page here.


Observe that Sample Course 1 now has two pages.   We may set the number of trials and time window allowed to students and click "UPDATE".   (These constraints can be changed at any time by overwriting, or removed by entering "0", into the trials and times boxes and then clicking "UPDATE".)


A page can be removed by clicking "REMOVE PAGE" or relocated in the list by changing its index and clicking "MOVE PAGE".

How to admit a student to your class

After creating a class, the only your student account will be enrolled in the class.   To change this and add or delete a student from your class, you will need the student's user id.   At Course Creation & Maintenance Report select the desired course from the drop-down selection tool and click on the "EDIT USERS OF THIS COURSE" button.


You will now be able to add/remove users to/from your course.   You will need the student's user id in either case.   Note that our Sample Course 1 now has two participants   –   Instructor1 and Instructor1stud.   We will add Student1 as a participant by entering this user id into the text region at bottom of the "EDIT USERS OF THIS COURSE" page and then clicking "ADD USER TO THIS COURSE".


Note that we now have three participants in Sample Course 1.


How to type mathematics

Typing mathematics is awkward work.   There is no universal agreement on many notations, and choices have to be made to render communication with our mathematics engine manageable.   As a result we have incorporated several rules, which are described below.

The four main rules you should keep in mind are the following.
  1. Functions written using parentheses about the input.   Thus   $\sin(x)$   rather than   $\sin\, x\;$ .
  2. Multiplication should be written using the symbol   "$\cdot$" .   Thus   $x\cdot y$   rather than   $xy$   or   $x\, y\; $ .
  3. Multiplication should be written with the exponent following the base as superscript.   Thus   $\sin(x)^2$   rather than   $\sin^2x$   or   $\sin^2(x)\; $ .
  4. When in doubt, use parentheses:   $\left(\sin(x)\right)^2$   works well.

Click here to practice typesetting mathematics.   You will be able to see how your entry is represented by our editor.   Functions should generally be chosen from the palette obtained from the hot-spot on the right of the editor.   Output should be examined for whether or not it corresponds to the desired.   It is worth familiarizing yourself with this page, as you can cut-and-paste from it to other math boxes throughout the site.
