Lesson COG 18
Task: Match picture to picture.
Prerequisites: ADT 1, ADT 5, ADT 6, COG 6, SEN 11—SEN 13
Concept: Pictures are not as desirable for teaching as the real objects because they are actually an abstract representation of an item. The interpretation of a three-dimensional form in a two-dimensional manner is usually more difficult than recognition of just the object itself. Many learning situations do require some ability to work with picture representations, which gives value to this task.
Behavioral Objective: Present five pictures, after having arranged five identical pictures in front of the student, and request the student to "please place these next to the ones like them." The student will place each picture next to the identical item to a 90% accuracy level for 20 trials.
Materials: Five pictures of items common to the student's environment, such as a toothbrush, pencil, or drinking cup, and an identical set of the same pictures.
Task Analysis:
1. Place only one picture on a table in front of the student and hand him or her two pictures, one of which is the exact match to the picture being presented. Ask the student to "place the picture like the one in front of you on the table." Physically guide the student in placing the correct picture on the table. Do not provide negative comments for incorrect actions, but give plenty of verbal praise when the student is successful. Reduce physical guidance until only the verbal cue is needed.
2. Add to Step 1 by placing another example on the table and giving its matching picture to the student no that there are two examples on the table and three in the student's possession.
3. Continuing the concept of Step 2, change the presentation to three pictures on the table and only the same three pictures being given to the student.
4. Continue Step 3, adding items until there are five pictures on the table and five pictures presented to the student.
