These documents deal with the administrative aspects of EDU, which we define to include all tasks other than creation of question banks. The full set of documents is available as a zip folder, and individual documents are available in pdf form.The amount of documentation needed for each individual user depends on the level of that user. An administrative unit needs to have one expert who is familiar with all of the documents; individual instructors need only be familiar with some of the documents.
EDUadministration (2 pages) is an overview of an administrative plan that uses Course Folders to maintain question banks and assignments for an indefinite period of time and Class Folders to maintain student records for individual classes. A file structure such as this simplifies EDU administration, particularly for multi-section courses where some instructors are only marginally acquainted with EDU.
EDUcoursefolders (1 page) is a step-by-step guide to those tasks needed to create and maintain a Course Folder, as described in the administration plan.
EDUtutorial (3 pages) is a tutorial that introduces EDU to newcomers. The tutorial includes examples of the tasks detailed in the EDUclassfolders and EDUstudentinfo documents. This tutorial can be used at institutions other than UNL by creating a course folder and uploading the Calcdemo.zip module.
EDUinstructorinfo (1 page) is an overview of the EDU folder structure and instructor-related documentation.
EDUstudentinfo (1 page) is a step-by-step guide to the process of registering for an EDU course and taking assignments.
EDUclassfolders (2 pages) contains directions for creating and maintaining a Class Folder. This file only includes the most important tasks: observing/re-grading student work and changing Assignment details.
EDUassignments (1 page) is a step-by-step guide to the process of creating Assignments from available Question Banks. Instructors who have access to Assignments created by others and wish to use them do not need to know how to create their own Assignments.
EDUgradebook (1 page) is a step-by-step guide for obtaining EDU grades in a form that can be pasted into a class grade spreadsheet. EDU currently assumes that all homework/quiz assignments are worth the number of points given in the assignment and that all mastery assignments are worth one point. An instructor who wants to choose a different scoring system must either manipulate the downloaded gradebook.xls or download and run the Perl script edu.pl.
EDUassessment is a Powerpoint presentation for a talk given on January 12, 2006 at the Joint Math Meeting.
Each of these folders contains a question bank designed for use with EDU, Maple TA, and other related packages, along with a detailed description of the questions. The questions banks were created with funding from an NSF DUE grant 0127777.

secant-tangent gives a visual demonstration of how the tangent line is approximated by a sequence of secant lines.
primer1 is an introduction to Maple designed for users who have no Maple experience.
primer2 is a demonstration of the use of formulas to represent functions and introduces basic commands for differentiation and integration.
solutions for the exercises in primer 2.
DEtools1 is a demonstration of the use of the DEtools package to plot direction fields and solutions for first order equations.
DEtools2 is a demonstration of the use of the DEtools package to plot direction fields and solution curves for systems of two first order equations.
odes is a demonstration of Maple commands for obtaining and graphing analytical and numerical solutions for differential equations and systems.
HeatIVP is a worksheet that prepares graphs and animations for solutions of the Cauchy problem for the heat equation.WaveIVP is a worksheet that prepares graphs and animations for solutions of the Cauchy problem for the wave equation.
DiffusionDisk is a worksheet that illustrates the use of Maple to solve homogeneous linear PDE's with constant coefficients on a bounded domain by the method of separation of variables. The worksheet solves the problem of radial diffusion in a disk. The worksheet assumes that the user knows the correct Sturm-Liouville equation and can solve the equation for the time-dependent factors by hand. (One can of course add more code to automate some of these simpler features.)
simplex is a worksheet for the simplex algorithm.
For best results, set up the following in the lower left corner of the Acrobat print dialog box:
Derivative Concept is a handout that briefly summarizes the concept of the derivative for functions of 1 variable, with emphasis on the geometric significance of the derivative.Directional Slope is a handout that lays the groundwork for the development of the directional derivative by considering the slope in a given direction of a linear function. Exercises are included.
Optimization is a handout that summarizes the theory and methods for for finding local and global extrema for functions of two variables.
Line Integrals is a handout that summarizes the theory and computational methods for integrals of vector fields along curves.
Flux Integrals is a handout that summarizes the theory and computational methods for integrals of vector fields through surfaces.
