+  This guide contains information about authoring WeBWorK problems. 

+  
+  * If you're just starting out, see the [[Author's Guide/Backgroundbackground information]] and basic problem templates first. 

+  * If you're working on a problem in a specific area you may find the more advanced templates useful. 

+  * If you're working on a problem and want to find out how to do one particular thing the index of problem techniques may be useful. 

+  * Use the online calculators to try things out. 

−  ==Templates== 

+  == Manuals and HOWTOs == 

−  Most people write problems starting from templates. Problems from the OPL can be modified to suit individual needs, or existing problem templates can be used to create new problems. 

−  * '''[[Problem Techniques]]''' This page lists templates for WeBWorK problems in alphabetical order. This collection of templates can also be accessed through the associated category page: [[:Category:Problem Techniques]] 

−  * '''[[:Category:Subject Area TemplatesSubject Area Templates]]''' Some may find it useful to use this page where templates are ordered by subject area. 

−  * '''[[:Category:Sample_ProblemsSample_Problems]]''' A third page with a collection of templates is this page of sample problems. 

−  +  * [[Problem Authoring Background Information]] 

−  +  * [[Tagging Problems]] with metadata for indexing and searching. 

−  * 
+  * [[Problem Authoring Best Practices]] for problem authoring. 
−  * 
+  * [[:Category:MathObjectsMathObjects]], an object system for manipulating mathematics in WeBWorK problems. 
−  +  * [[PGLabs]], online calculators for immediate display of MathObjects and PG markup language (PGML) These are very helpful for learning the syntax. 

−  ** '''[[Introduction to Contexts]]'''  how to use Numeric, Complex, Vector, Matrix, Interval, and other contexts in problems. 

−  ** '''[[Reduction rules for MathObject Formulas]]'''  a table of ''The Reduction Rules and their Actions''. 

−  ** '''[https://testcourses.webwork.maa.org/webwork2/PREP14_Problem_Authoring/Workshop2/?login_practice_user=true Davide Cervone's presentation on MathObjects to PREP, June, 2014]''' 

−  * '''[[:Category:PGMLPGML]]'''  information on authoring problem using the PGML markup language. 

−  ** '''[[SampleProblem4 Template 4]]'''  the standard outline of a problem using PGML, which includes a ''tagging and description section'', ''an initialization section'', ''a problem setup section'', ''a text section'', and optional ''answer and solution sections''. 

−  ** '''[https://testcourses.webwork.maa.org/webwork2/PREP14_Problem_Authoring/Workshop3PGML/?login_practice_user=true Davide Cervone's presentation on PGML to PREP, June, 2014]''' 

−  * '''[[PGLabsPGLabs]]'''  try out code fragments on line including code fragments containing MathObjects and PGML. This is a quick way to learn the fine points of the MathObject and PGML syntax. 

−  ==Templates, programming examples, and problem libraries from the University of Lethbridge== 

+  == Examples == 

−  Sean Fitzpatrick (sean.fitzpatrick@uleth.ca) contributed the following: 

+  * [[BasicProblemTemplatesBasic Problem Templates]] 

+  ** [[SampleProblem1Template 1]] (the basic structure of a WeBWorK PG problem file) ([[oldstyle example templateSampleProblem1a]]) 

+  ** [[SampleProblem2Template 2]] (formulas, multiple choice, and string entry problems) 

+  ** [[SampleProblem3Template 3]] (dynamically generated graphs) 

+  * More Advanced Templates 

−  This summer, one of my colleagues hired a student to help her go through all of the libraries, marcos, contexts, etc. and put together a collection 

+  == Reference documents == 

−  of templates and programming examples. I got permission from her to put everything on a public GitHub repository; you can find the fruits of their 

−  efforts here: 

−  https://github.com/ULethMathCS/WeBWorK 

+  * [http://webwork.maa.org/doc/cvs/ PG macro/library documentation from CVS] 

−  
+  * [[IndexOfProblemTechniquesIndex of Problem Techniques]] 

−  The programming examples are not questions. They're an attempt at producing an exhaustive list of every possible way of inputting and evaluating 

−  something using the various contexts. 

−  In the documentation there's a nice flowchart for deciding which context to use for a given problem. 

−  
−  I hope this is useful. It's the beginnings of what will hopefully be a longer project (done mostly over summers), so it's not yet as polished as it 

−  could be. 

−  
−  == Reference documents and manuals == 

−  * '''[[Problem Authoring Videos]]''', recordings from the PREP 2015 Problem Authoring Workshop. 

−  * [[:Category:Applets'''Applets''']], how to embed Flash and Java applets into WeBWorK questions. 

−  * '''[[SequentialProblems]]''' now replaced by [[Scaffold]] revealing the problem one step at a time 

−  * '''[https://webwork.maa.org/pod/ POD]'''  POD (for WeBWorK/PG 2.15) = "plain old documentation"  original documentation embedded in the code files  this is the place to find the most complete and most technical description of macro behaviors. 

−  * '''[[:File:WeBWorK_Problem_Authoring_Tutorial.pdf WeBWorK Problem Authoring Tutorial]]''' aimed at people who already know TeX, but need to learn about Perl, PG, and MathObjects (pdf file). 

−  * '''[[Customize_CourseCustomize Course]]''' This page includes a bit of code that allows student to obtain a new version of a problem. 

−  * '''[[TrainingAuthors Notes on training authors]]''', and suggestions for further documentation Sam Hathaway 

−  * The Good Questions project at Cornell University [http://www.math.cornell.edu/~GoodQuestions/] 

−  * '''[[Converting CAPA problems for use with WeBWorK]]''' (This article has been retained as a historical document.)
