Case:
Gary Winston Barnes (GWB) has problems in completing homework assignments in Mr. Harvard's class. Some students in class have commented that Gary is drinking alcohol after school, yet the teacher cannot confirm such allegations. GWB claims to complete assignments, yet at the end of the day, no assignments belonging to Gary are present. Homework is assigned each night yet his current rate of completion is one homework assignment completed per 2-week period. Mr. Harvard wants to increase the number of homework assignments GWB turns in. The teacher suspects that the curriculum may be too advanced for the student and therefore the antecedent is task difficulty. The teacher further suspects that the consequence is task avoidance.

Mr. Harvard's intervention involves reinforcing GWB for asking for alternate assignments, ask for help, or break. When Gary completes partial assignments, he will earn free time in class. Gradually, the teacher will increase expectations and eventually, Gary will have to submit fully completed assignments in order to earn free time during class. As part of the second treatment condition, Mr. Harvard intends to modify assignments to ensure that Gary is being assigned curriculum that is appropriate for his performance level. As the homework completion rate improves, the teacher will further increase expectations and will focus on the accuracy of assignments being submitted by GWB.

During week 1 thru 3, the teacher collects baseline data (Baseline: Phase A)

During weeks 4 through 6 he begins the intervention of allowing GWB to ask for alternate tasks or ask for help/break (Treatment 1: Phase B).

During weeks 7 through 9, the teacher decides to add modifying assignments to make sure they are at student's ability level in addition to allowing JM to ask for break/help/alternate tasks (Treatment 2: Phase C).

During weeks 3-8 Mr. Smith had the Aide collect agreement data.

Baseline - A (# of HW assignments Turned In)

Week 1
Teacher - 1 Observer - Not Obs (NO)

Week 2
Teacher - 1 Observer - Not Obs (NO)

Week 3
Teacher - 1 Observer - 1

Intervention B: ask for alternate tasks or ask for help/break

Week 4
Teacher - 3 Observer - 3

Week 5
Teacher - 3 Observer - 2

Week 6
Teacher - 4 Observer - 3

Intervention C: Modify Assignment in addition to JM asking for alternate task/break/help

Week 7
Teacher - 4 Observer - 4

Week 8
Teacher - 6 Observer - 6

Week 9
Teacher - 5

Questions related to Case:

• Identify the research design:
• Calculate agreement check and tell me if it is acceptable.
• Graph data. Hint: make sure all sections of graph are appropriately labeled (also, don't forget that you DO NOT graph data from the agreement check person)
• Interpret the efficacy of the intervention.
