Advanced Content

Randomized Content

High level aspects of adding randomized content to your assignments

Using Sage

We discuss aspects of Sage we use, and provide some core sage functions we use.

How sage interacts with Ximera.

Randomizing with Sage

Common Sage Functions and Details

Randomizing Problem Order

Common Sage Functions and Details

Complex Validation

Validation Types

Black Magic Techniques

A Collection of very advanced techniques that may or may not break things.

Generating Answer Boxes

How to generate a custom number of answer boxes on the fly via sage.

Overleaf Template

We provide a link to an Overleaf Template that can be copied/saved and used for those without the ability, interest, and/or knowledge to install things locally.

Existing Custom Validators

isPositive

This demonstrates a very basic custom validator, which returns correct if the submitted answer is positive.

sameParity

This demonstrates a slightly more complex validator that uses both user input and supplied answer.

caseInsensitive

Demonstrates a way to check student string against provided string, but without case sensitivity

multiAns

Demonstrates a way to provide multiple acceptable answers from students.

sameDerivative

Checks student submission and supplied problem to see if they have the same derivative

factorCheck

Checks provided factoring to see if it matches author’s factoring.

samePlane

This demonstrates the validator that tests for points to represent the same plane.

Numeric Targeted Feedback

A requested proof of concept

Matrix Equality

An attempt to develop a format for student answers, to allow students to enter a matrix and validate the answer as correct if it equals the instructor’s matrix.

Convert to RREF

This “validator” is actually a set of subfunctions to be used in validators. This reduces a numeric matrix into reduced row echelon form.

Known Issues

Known issues with validation - either default or custom.

Question Design

Interval Answer Formats

Some Tips on Best Practices for Writing Problems.

Interval Answer Formats

How to get students to input an interval as an answer.

Randomized Multiple Choice

Equalities with Radicals

A solution to the problem of making radical + value = radical + value style problems procedurally that remain suitably “nice” for precalc students.

Cubic with Two Factorable Derivatives

How to generate “nice” polynomials that factor well, along with its first and second derivative.
