Escalas

Moodle 2.x

Las escalas son una forma de evaluar o valorar el desempeño de un alumno. Moodle ofrece un conjunto estándar de escalas numéricas. También es posible crear escalas personalizadas que pueden estar disponibles a nivel del sitio. Por ejemplo, usted puede darles a los estudiantes una palabra o pequeña frase como una forma de valorar o proporcionarle retroalimentación a un estudiantes.

Las escalas pueden usarse en Foros, Glosarios y Tareas para valorar y/o para calificar la actividad de un estudiante.

Escalas estándar

Moodle incluye 100 diferentes escalas numéricas que no pueden editarse , y un ejemplo no-numérico.

Numérica

Moodle incluye escalas numéricas que van desde un mínimo de 1 hasta un máximo de 100. Por ejemplo, al seleccionar una escala de 10, permitirá una valoración en una escala del 1 al 10. Las escalas numéricas pueden calcularse como una calificación.

Creando una nueva escala

Losadministradores, los maestros con derechos de edición y cualquier usuario con la capacidad de manage scales role capability pueden crear nuevas escalas

Creando escalas para curso

1. Click the "Add a new scale" button in Settings > Grade administration > Scales or via the gradebook Scales tab.
2. On the next page give your scale a name in the Name box (highlighted in red in the screenshot) that will identify it among other scales.
   

   Creating a new scale screen: Name, Scale, Description areas
3. In the Scale box (highlighted in green), create your scale. Each item in the scale should be separated by a comma. You can use as many options here as you require. You must order the comma separated elements in increasing order of value. For example, an A,B,C,D scale must be entered as D,C,B,A.
4. Write a detailed description in the Description box (highlighted in blue) for your scale. Your students will have access to the description, and you can use this to give them additional feedback. The more details you put in the description, the more students will understand what each scale item means.

Creando una escala estándar

An administrator can create a standard scale which can be used in any course in Settings > Site administration > Grades > Scales.

Using a scale

First the teacher needs to assign a specific scale to the activity using a drop down menu in the activities setting. Then the teacher and/or students can rate an activity element (for example, a post in a forum) with the pre-defined scale.

Editando una escala

If a scale has not yet been used, you will see an edit, move, and delete icon in the edit column.

Once a scale is used for an activity, it is no longer possible to move or delete it, and you can only edit the scale name and description.

Escalas de ejemplo

• The Cool Scale - Not cool, Not very cool, Fairly cool, Cool, Very cool, The coolest thing ever!
  • (Valued as 0/5pts, 1/5pt, 2/5pts, 3/5pts, 4/5pts, and 5/5pts respectively in any normalized aggregation method)
  • (Valued as 1, 2, 3, 4, 5, and 6 respectively in the sum aggregation method)

• General Introductions (The Affirmative Scale) - Welcome!, Glad to have you here!, Great post!
  • (Valued as 0/2pts, 1/2pt, and 2/2pts respectively in any normalized aggregation method)

• If you would like two options in your scale (incomplete and complete) type "incomplete, complete" in the scale box.
  • (Valued as 0/1pts and 1/1pt respectively in any normalized aggregation method like weighted mean, mean, simple weighted mean, etc.)
  • (Valued as 1 and 2 respectively in the sum aggregation method)

• Generic Social Forum (This scale only worked prior to the averaging function) - Please clarify., I don’t understand., Hmmm. Tell me more., Interesting, Very cool., Awesome!
  • (Valued as 0/6pts, 1/6pt, 2/6pts, 3/6pts, 4/6pts, 5/6pts, and 6/6pts respectively in any normalized aggregation method)

• "Stars" ☆----, ☆☆---, ☆☆☆--, ☆☆☆☆-, ☆☆☆☆☆
  • (Valued as 0/4pts, 1/4pt, 2/4pts, 3/4pts, and 4/4pts respectively in any normalized aggregation method)
  • (Valued as 1, 2, 3, 4, and 5 respectively in the sum aggregation method)
    

Valores calculados como porcentajes de puntuación

Moodle uses the last entry to determine the number of points in the scale for computing percentages. For example, if your scale is 0,5,6,7,8,9,10 then Moodle will use a 0-6 or 1-7 point scale depending on your chosen aggregation method.

• When using a normalized aggregation method, 0 will become 0/6, 5 will become 1/6, 6 will become 2/6, 7 will become 3/6, 8 will become 4/6, 9 will become 5/6, and 10 will become 6/6 for grade computation, respectively.
• When using the sum aggregation method, 0 will become 1, 5 will become 2, 6 will become 3, 7 will become 4, 8 will become 5, 9 will become 6, and 10 will become 7.

Either way, the numbers you enter for your scale are NOT calculated as entered, the system calculates the number of non-zero entries and then creates a scale from 0 to the total number of entries (n) with their values calculates as 0/n, 1/n, 2/n, 3/n....

TIP: If your scale is a custom non-value (not a number), Moodle's behavior in combining or averaging the scores into a percentage value is unpredictable. When an average or aggregate is important, then it is a good idea to stick with the standard 100% scale to compute an overall grade.

Tip: Some sites do not like the "0" (zero) in any normalized aggregation method.
