 
                  The Derbyshire Language Scheme has long been used with pupils with severe learning difficulties. This is just  one of a
                  variety of language programmes for developing pupils’ use and  understanding of spoken language. 
                  
                  The  Derbyshire Language Scheme uses specific test situations to determine pupils'  level of comprehension and expressive
                  language.
 
                  The Derbyshire Language Scheme (DLS) can be used with all pupils for whom
                  building vocabularies and teaching understanding and use of simple sentences,  including basic grammar and syntax, are relevant
                  goals.
                  
                  The DLS is split into three stages. The focus here  is the Simple Sentence
                  stage which aims to teach pupils to understand and use a  range of sentences of increasing complexity.
                  
                  If  you are not familiar with the DLS, have a look at  this summary. 
                  
                  
The DLS introduces the important concept of  Information Carrying Words
                  (ICWs) as a  gauge of the level of difficulty of instructions.
                  
The level of difficulty is  measured by counting the number of words which the pupil must understand
                  in order to respond to the command correctly. For instance, the pupil has to  respond to one ICW in the  command ‘Wash the doll’ when there is a flannel, a doll and teddy with  which
                  to play. The pupil has to respond to the word ‘doll’. It is assumed that  ‘wash’ has already been
                  learned and it is evident what the child has to do from  the presence of the flannel.
Levels 1 to 4 of the DLS are determined by the number of ICWs that appear in commands or descriptions  for the recommended activities at each level. 
                  
                  Read the following document  for a description of the assessment procedures.

                  The DLS complete  package includes a Detailed Test of Comprehension. However,
                  you may wish to  consider how you would engineer some simple test situations.
                  
                  Look  at these pictures. Suggest a structure that they can be used to assess. What  Level of the DLS might this be?
In the test depicted on the previous page, the child is instructed to show or select a particular picture, eg 'Where's
                  the spoon on  the plate?' There are two objects to choose between and two places. This  particular request contains two ICWs,  'spoon' and 'plate', and is at the two word comprehension level. Note that
                  understanding of the preposition 'on' is not being tested. The objects are  either on the plate or in the box. There would
                  have to be additional pictures  to test understanding at the three word level.
                  
                  Use of pictures is always somewhat difficult. At the three and four word levels in  particular it is easier to use objects.
This video shows how a teaching assistant uses simple,  objective tests to assess a child’s knowledge of structures
                  at the two word  level. What are the key skills and strategies of this teaching assistant? Can  you see this testing being
                  done easily in the context of a regular teaching  activity? 
                  
Note how the assessment materials are presented. Do you think the assessments were  carried out properly? After you
                  have watched the video, read the commentary.
                  
                  
 
                  In the video on the previous page the teaching  assistant used these four pictures with Zoe to assess object and place
                  at the  two word level.
                  
                  
This is a progression from using actual objects. Many children require lots of learning experiences to associate pictures with actual objects, particularly line drawings of miniatures like these.
In this video a teaching assistant tries to assess  another child's knowledge of structures at the two word level. 
                  
                  Again, can you see this testing being done easily in the context of a regular teaching  activity? Note how the assessment
                  materials are presented. How do you think you  would do these assessments with older children in ways that are  age-appropriate?
                  After you have watched the video, read the commentary.
                  
                  
 The  teacher's grasp of the concept of the information carrying word
                  is essential. The level of difficulty of a request or instruction is measured by  counting the number of words which
                  the pupil must understand in order to  respond correctly. Judging whether words in a statement or request are ICWs depends on an analysis of the  information available to the child from the context
                  in which the adult is  speaking. 
                  
Consider  why this concept is so essential in the special context of teaching pupils with  complex needs. Make a list
                  of the reasons.
