| {{Actualizar}}
| |
| {{Versiones| Esta documentación es para Moodle 3.1 y más recientes. Existe documentación anterior (del 2014) en [[30/Tipo de pregunta fórmulas]].}}

| | |
| =Documentación completa=
| |
| | |
| La documentación para el tipo de pregunta '''Fórmulas''' se basa en la del [https://code.google.com/archive/p/moodle-coordinate-question/wikis/Documentation.wiki '''proyecto original de Hon Wai Lau'''] (disponible en Google Code Archive). El contenido se ha modificado y actualizado ligeramente para que coincida con '''Moodle 2.0''' y posteriores.

| Also, the original examples in [https://code.google.com/archive/p/moodle-coordinate-question/wikis/Documentation.wiki Hon Wai Lau's original project ] can be found in the file called 'sample-formulas-questions.xml' (Moodle XML format) located in the 'moodle/question/type/formulas/sample' folder. Use the [[Importar preguntas]] option (Moodle XML) to put them into your [[Banco de preguntas]] and see how they work.
| |
| | |
| =Características=
| |
| | |
| * '''Random values'''. Each student can receive questions with unique values and wording.
| |
| * '''Multiple subquestions'''. Multiple subquestions can be made to share the same set of random variables.
| |
| * '''Multiple answers'''. Multiple answer boxes can be used for one subquestion.
| |
| * '''Different answer types'''. Both numerical answers with units and algebraic answers can be used.
| |
| * '''Grading criterion'''. In addition to simple absolute error, responses from students can be graded using any formula.
| |
| * '''Units'''. Supports units and SI unit conversions. SI units with different SI prefixes are accepted using a built-in conversion rule.
| |
| * '''Multiple trials'''. A finite or infinite number of trials can be specified for each subquestion.
| |
| | |
| =El tipo de pregunta '''Fórmulas''' es para Usted!=
| |
| El tipo de pregunta Formulas es un plugin para Moodle con valores aleatorios y campos de respuesta múltiple. Los campos de respuesta pueden colocarse en cualquier parte de la pregunta, para que Usted pueda crear estructuras de respuesta variadas; como por ejemplo, coordinadas, polinomio, matríz, etc. Otras características, tales como revisión de unidades y sub-preguntas múltiples, también están disponibles. Estas funcionalidades pueden simplificar la cración de preguntas en muchos campos relacionados con matemáticas, números y unidades, como por ejemplo, física e ingenierías.
| |
| | |
| '''¡Si Usted está tratando con problemas como los descritos debajo, entonces el tipo de pregunta Formulas es para Usted!'''
| |
| | |
| Tome un problema en ingeniería estructural, por ejemplo, que puede involucrar varios parámetros cun un número de valores fijos y conocidos, como por ejemplo:
| |
| | |
| '''Parámetro''' '''Valores posibles'''
| |
| Bolt diameter (mm) 16, 20, 22, 24, 27, 30, 36
| |
| Plate thickness (mm) 16, 20, 25, 35, 40, 50
| |
| Steel strength (MPa) 300, 345, 350, 380
| |
| Concrete strength (MPa) 20, 25, 30
| |
| Reinforcing bar diameter (mm) 9.5, 12.7, 15.9, 19.1, 22.2, 25.4
| |
| | |
| A question that involves the five parameters, each with their possible values, has 7 x 6 x 4 x 3 x 6 = 3024 different possible versions, much more than the limit of 100 in the Calculated question.
| |
| | |
| Even a simple question in basic mathematics can have a large number of possible versions. The following one has 5 x 5 x 8 = 200 different possible versions:
| |
| | |
| Find the value of ''x'' = ''a''*(''b'' + ''c'')
| |
| where
| |
| • ''a'' is an odd number between and including 1 and 9
| |
| • ''b'' is an even number between and including 2 and 10
| |
| • ''c'' is an integer value between and including 1 to 3 or 7 to 11
| |
| | |
| This kind of question can be easily created using the Formulas question. When creating the question, you would enter your sets of numbers in the 'Random variables' field as:
| |
| | |
| a = {1:10:2};
| |
| b = {2:11:2};
| |
| c = {1, 2, 3, 7:12};
| |
| | |
| Note that sets of numbers can be in the format {start:stop:interval}, for example {1:10:2} and {2:11:2}. (The stop value is not included in the set and the interval is set to 1 when not specified). Sets of numbers can also be in the format of a list such as {1,2,3} for the set of numbers 1, 2 and 3. They can even be in a combination of the two formats, such as {1, 2, 3, 7:12}.
| |
| | |
| When an attempt is started, ''a'', ''b'', and ''c'' will take a value drawn from the corresponding set at random. If you want, you can define other variables as a function of the random ones in the 'Global variables' field. For instance, if you need the value of ''a'' + 2*''b'' somewhere in your question (that is the main question, subquestions, hints and feedbacks), just define a new variable, say ''d'', in the 'Global variables' field:
| |
| | |
| d = a+2*b;
| |
| | |
| Once you have defined your variables, you can display them by putting them in curly braces, i.e. {a}, {b}, {c}, {d}, anywhere in the question.
| |
| | |
| Another advantage of the Formulas question is that a question can have several subquestions, called ‘parts’, that can share the same variables. The Formulas question also has a complete unit system that is quite useful for physics and engineering.
| |
| | |
| The '''Formulas question''' type is very powerful and permits the making of a wide range of questions. Although mastering all its possibilities require some practice, the basics can be learned quickly.

| |
| The Formulas question was originally written by [https://moodle.org/user/view.php?id=1069069&course=5 Hon Wai Lau] in about one year during 2009 and 2010, while he was working for the Physics Department at the [http://www.ust.hk/ Hong Kong University of Science and Technology].
| |
| | |
| Hon Wai Lau's Formulas question original project can be found on [https://code.google.com/archive/p/moodle-coordinate-question/ Google Code Archive]. Note that the initial name 'Coordinate question ' was later changed to 'Formulas question'. Hon Wai Lau's original Formulas question is compatible with Moodle 1.9 and 2.0.
| |
| | |
| The Formulas question was upgraded to the new question engine, introduced in Moodle 2.1, by [https://moodle.org/user/view.php?id=8026&course=5 Jean-Michel Védrine], professor of Statistics and Computing at the Institut Universitaire de Technologie in Saint-Étienne, France. The upgraded version of the Formulas question is compatible with Moodle 2.3 and later versions, currently up to Moodle 3.1.
| |
| | |
| The current Formulas question project can be found [https://github.com/jmvedrine/moodle-qtype_formulas on GitHub].
| |
| | |
| =Maintainer(s)=
| |
| [https://moodle.org/user/view.php?id=8026&course=5 Jean-Michel Védrine] has maintained the Formulas question type plugin until 2017. He is now back in force for 2018.
| |
| | |
| =Installación=
| |
| The Formulas question is a Moodle plugin, so you or your Administrator must [[Instalar plugins|instalarlo]].
| |
| | |
| Prior to installing the Formulas question though, you need to install [[Instalar plugins|instalar otro plugin]]., that is Tim Hunt's adaptive multipart behaviour, [https://github.com/maths/moodle-qbehaviour_adaptivemultipart available from GitHub] or [https://moodle.org/plugins/view.php?plugin=qbehaviour_adaptivemultipart from the Moodle Plugins directory]. Note that you need version 3.3 or newer of this behaviour, because the Formulas question will not work with previous versions.
| |
| | |
| You can then install the Formulas question either from the Moodle Plugins directory, from GitHub or from a zip file:
| |
| | |
| '''Installing from the Moodle Plugins directory'''
| |
| | |
| The Formulas question is available from [https://moodle.org/plugins/view.php?plugin=qtype_formulas the Moodle Plugins drectory]. Install the Formulas question as any other Moodle question type plugin.
| |
| | |
| '''Installing from GitHub'''
| |
| | |
| The Formulas question is available at [https://github.com/jmvedrine/moodle-qtype_formulas the author's Github repository]. To install the question, type the following commands in the root of your Moodle install:
| |
| git clone git://github.com/jmvedrine/moodle-qtype_formulas.git question/type/formulas echo '/question/type/formulas/' >> .git/info/exclude
| |
| | |
| '''Installing from a zip file'''
| |
| | |
| Download the zip file [https://github.com/jmvedrine/moodle-qtype_formulas from GitHub]. Unzip the file in the 'question/type' folder and then rename the new folder to 'formulas'.
