1 1 Introduction

The probsoln package is designed for teachers or lecturers who want to create problem -sheets for their students. This package was designed with mathematics problems in -mind, but can be used for other subjects as well. The idea is to create a file -containing a large number of problems with their solutions which can be read in - - - -by LATEX, and then select a number of problems to typeset. This means -that once the database has been set up, each year you can easily create a new -problem sheet that is sufficiently different from the previous year, thus preventing -the temptation of current students seeking out the previous year’s students, -and checking out their answers. There is also an option that can be passed to -the package to determine whether or not the solutions should be printed. In -this way, one file can either produce the student’s version or the teacher’s +class="ec-lmss-10x-x-109">probsoln package is designed for teachers or lecturers who want to +create problem sheets for their students.

The boolean variable showanswers

The boolean variable showanswers determines whether the answers should be displayed. You can use this value with the ifthen package to specify different text -depending on whether the solutions should be displayed. For example: +class="ec-lmss-10x-x-109">ifthen package to specify +different text depending on whether the solutions should be displayed. For +example: -

8.1 Randomly Selecting Problems Not Selected in Previous Documents

+

Suppose you have a large set of questions that you want to randomly select for +assignments and exams. The chances are, you don’t want to include questions +that have been previously set for, say, the last three years. That is, you don’t +want to select questions the students may already have seen. As from version +3.03, you can now do this. +

The probsoln package defaults to the UK academic year, which starts in +September. If this isn’t appropriate, you can change it using: +

\SetStartMonth  \foreachproblem[⟨data set⟩]{⟨body⟩}
-

+class="ec-lmtt-10x-x-109">\SetStartMonth{⟨n⟩}

+

+where ⟨n⟩ is the number of the month. (1 = January, 2 = February, +etc.) +

The start year is the calender year in effect when the academic +year started. For example, if this is the academic year 2011/12, then +the start year is 2011. This is automatically set to the start of the +current academic year. It is also updated when \SetStartMonth is +used.1 +If you want to set it to a specific year, you can use: +

\SetStartYear  \SetStartYear{⟨year⟩}
+

+For example: \SetStartYear{2008} indicates the academic year 2008/9. +

There are two files concerned with previously used labels. They are: +

+The previously used labels file
This keeps track of all problems used in + previous years, as well as problems used by other documents that have + this as their previously used labels file, and it contains the problem + labels from the last run of the current document. +
+The current used labels file
This defaults to \jobname.prb, but the name can + be changed using: +

\SetUsedFileName  \SetUsedFileName{⟨name⟩}
+

+ This file keeps track of all the labels used in the current document from + the previous LATEX run. Note that if you want to delete this file, first + clear it using + + +

\ClearUsedFile  \ClearUsedFile{⟨file⟩}
+

+ in place of \ExcludePreviousFile{⟨file⟩}, described below. The + argument ⟨file⟩ is the previously used labels file described above. + \ClearUsedFile will remove all labels in the current used labels file from + the previously used labels file and clear the current used labels file. Once + this file is empty, it may then be deleted. +

+
+

Before loading randomly selected problems, first specify the previously used +labels file with the command: +

\ExcludePreviousFile  \ExcludePreviousFile[⟨number of years⟩]{⟨file +name⟩}
+

+where ⟨file name⟩ is the name of the previously used file. The optional argument +⟨number of years⟩ specifies the year cut-off. This defaults to 3, which means that +only those labels used this year or the previous 2 years will be kept. Any +problems used before then may be reused. +

I want to set assignments on each topic and an exam +at the end of the year (as well as a resit or second sitting paper). I’ve got +databases with problems for each topic, but the first and second sitting +exams mustn’t include any of the problems used in the assignments +or any problems used in assignments or exams for the previous two +academic years.

9 Iterating Through Datasets

+

Once you have defined all your problems for a given data set, you can use an +individual problem with \useproblem (see §7 Using a Problem) but it is more +likely that you will want to iterate through all the problems so that +you don’t need to remember the labels of all the problems you have +defined. +

\foreachproblem  \foreachproblem[⟨data set⟩]{⟨body⟩}
+

This does ⟨body⟩ for each problem in the given data set. If ⟨data set⟩ is omitted, the -default data set is used. Within ⟨body⟩ you can use -

\thisproblem  \thisproblem
+

to use the current problem and -

\thisproblemlabel  \thisproblemlabel
-

+

\thisproblemlabel  \thisproblemlabel
+

to access the current label. If the problem requires arguments, and no default -arguments were supplied in the problem definition or the package option usedefaultargs -was not used, then you will be prompted for arguments, so if you want to use this -approach you will need to use LATEX in interactive mode. If you do provide -arguments, they will be stored in the event that you need to iterate through the data -set again. The arguments will be included in \thisproblem, so you only need to use +arguments were supplied in the problem definition or the package option \thisproblem without having to specify \useproblem. -

For example, to iterate through all problems in the default data set: +class="ec-lmss-10x-x-109">usedefaultargs was not used, then you will be prompted for arguments, so if you + + +want to use this approach you will need to use LATEX in interactive mode. If +you do provide arguments, they will be stored in the event that you need to +iterate through the data set again.

The chances are, you don't want to +%include questions that have been previously set for, say, the last +%three years. That is, you don't want to select questions the +%students may already have seen. As from version 3.03, you can now do +%this. +% +%The \sty{probsoln} package defaults to the UK academic year, which +%starts in September. If this isn't appropriate, you can change it +%using: +%\begin{definition}[\DescribeMacro{\SetStartMonth}] +%\cs{SetStartMonth}\marg{n} +%\end{definition} +%where \meta{n} is the number of the month. (1 = January, 2 = +%February, etc.) +% +%The \emph{start year} is the calender year in effect when the +%academic year started. For example, if this is the academic year +%2011/12, then the start year is 2011. This is automatically set to +%the start of the current academic year. It is also updated when +%\cs{SetStartMonth} is used.\footnote{So don't use \cs{SetStartMonth} +%after \cs{SetStartYear}.} If you want to set it to a specific year, +%you can use: +%\begin{definition}[\DescribeMacro{\SetStartYear}] +%\cs{SetStartYear}\marg{year} +%\end{definition} +%For example: \verb|\SetStartYear{2008}| indicates the academic year +%2008/9. +% +%There are two files concerned with previously used labels.

Note that if you want to +% delete this file, first clear it using +% \begin{definition}[\DescribeMacro{\ClearUsedFile}] +% \cs{ClearUsedFile}\marg{file} +% \end{definition} +% in place of \cs{ExcludePreviousFile}\marg{file}, described below. +% The argument \meta{file} is the previously used labels file +% described above. \cs{ClearUsedFile} will remove all labels in +% the current used labels file from the previously used labels file +% and clear the current used labels file. Once this file is empty, +% it may then be deleted. +% +%\end{description} +% +%Before loading randomly selected problems, first specify the +%previously used labels file with the command: +%\begin{definition}[\DescribeMacro{\ExcludePreviousFile}] +%\cs{ExcludePreviousFile}\oarg{number of years}\marg{file name} +%\end{definition} +%where \meta{file name} is the name of the previously used file.
