The exerquiz package: The userbmintrvl option

This article is motivated by an AcroTeX user (Thor G). He wants to ask his students to make a series of calculations, the result of which is to be entered into a \RespBoxMath input box. He is willing to accept the response as correct if the response falls into a designated interval [a,b].

The userbmintrvl option of exerquiz includes the definition of the command \rbmIntrvl, which is discussed in this article, is the implementation of this feature request by Thor G.

This feature requires exerquiz, dated 2021/04/24 or later. This article uses the dljslib package, dated 2021/04/04 or later.

Full functionality is obtained by downloading the file to your computer and opening in Adobe Reader. The article uses the useDeNums and useEnNums options of the dljslib.

eqexam: A Matching-type Problem

With a little effort, a problem* environment can be exploited to create a matching-type problem. The eqe_matching.pdf is an exam created from the exam environment of the eqexam package; the exam has one matching-type question. A second demonstration file named eqe_matching-rt.pdf has the same question but the entries in the columns are randomized.  The markup of these files requires the eqexam package dated 2021/02/26 or later. The matching-type question is completely compatible with the eqexam system, such questions respond correctly to all of eqexam options.

Exerquiz: Matching-type questions

A variation on a text fill-in question is a type of question based on
matching the question to the answer. The author poses a series of questions with a fill-in text field (perhaps created by \RespBoxTxt). As a companion to this series of text fill-in questions is a list of possible of answers. The student answers a question by entering a letter corresponding to the perceived correct answer. The quizzes in the PDF link below illustrate this concept.

Continue reading qz-matching.pdf in Adobe Acrobat Reader DC, outside of a browser.

Please review the companion article qz-matching-rt.pdf in which the
questions and choices are randomized.

eforms: Studies in Radio Button Fields

Some PDF previewer applications, notably PDF-XChange and
evince, do not handle radio buttons in the same way as do
AA/AR. A PDF viewer may not support PDF forms at all (such as
SumatraPDF), while others, such as TeXworks may supply
the appearances but not the functionality. PDF-XChange
supports PDF forms and Acrobat JavaScript, but handles radio
buttons differently. Continue Reading →

eqexam: Methods of inserting figures

In this article, we survey various methods of incorporating a figure into a problem. There are two placement locations for the figure: (1) in the work area, and (2) in the questions area.

Traditionally (for eqexam documents), the figure is included as part of the work area; these methods has been documented for many years, but will be illustrated here nonetheless. The primary focus of this document is on positioning the figure within the question itself. Continue Reading →

eforms: Enhanced Preview

Some LaTeX authors use a non-conforming PDF reader as a PDF-previewer, in the same way they use a DVI-previewer. Such non-conforming readers do not necessarily support form fields and the JavaScript they contain. The macro \previewOn has been available for many years, when activated, eforms typesets a rectangular box around a form fields so they become visible to one using a DVI- or PDF-previewer; recently, the eforms package (dated 2019/05/24 or later) supports an enhanced preview.
