Presentation Transcript
  • Jasmine
  • 6th grade
  • Referred by teacher for problems with math
    • Failed first semester
  • May have difficulty with basic math fact knowledge, which in turn is affecting her math problem solving skills.
  • Concerns began in 2nd grade
    • Difficulty with addition facts
  • Has not received any special interventions for math
  • Prefers to work with a partner during independent math work time
    • May be copying answers from a friend
  • Complains about the difficulty of her math assignments and appears sad when math work is distributed
    • Reportedly continues to put forth her best effort

problem validation2
Problem Validation
  • Records Review
    • B’s and C’s in other classes
    • Scored in basic range on 5th grade ISTEP
    • Good attendance
    • School problems, study skills
  • Parent Interview
    • No developmental, medical, behavioral, social problems
    • Doesn’t talk to Jasmine about school
    • Sister helps with homework
problem validation3
Problem Validation
  • 6th Grade Teacher Interview
    • Behavior within normal limits
    • Does well in other areas
  • 4th and 5th Grade Teacher Interview
    • Had problems with math, but did well enough to avoid summer school
    • Problems with basic math skills and problem solving
  • Classroom Observations
    • Math and Language Arts
    • Math- on task 80% of time
    • Off task- socializing
  • “Math Computation: Increase Accuracy By Intermixing Easy and Challenging Computation Problems” from Intervention Central
    • Uses worksheets that intersperse “easy” problems with “challenging” problems
      • If student completes alone– 1:1 ratio
      • If problems are read aloud to the student– 3:1 ratio
research review
Research Review
  • Hawkins, Skinner, and Oliver (2005)
  • Mathematical accuracy of fifth grade students was enhanced when easy problems were interspersed with more difficult problems
  • Suggested that the mixture of easy and difficult problems helped to enhance the students’ feelings of success
    • Increases the rate of reinforcement for working on assignments
research review1
Research Review
  • Cates and Skinner (2000)
  • High school students in remedial math exposed to three pairs of mathematics computation assignments
    • 3 control assignments containing15 target problems
    • 3 paired experimental assignments containing either 15 (0% more), 18 (20% more), or 21 (40% more) equivalent target problems.
    • Each experimental assignment lengthened by interspersing additional problems following every 3rd target problem.
  • Significantly more students rated the experimental assignment more favorably for time, effort, and difficulty and chose the experimental assignment for homework
  • Need to create math computation worksheets that contain a mixture of easy and challenging problems using worksheet generator
      • Must identify problem types Jasmine finds challenging/easy
      • Ex. Multiplying 2 digit by 2 digit vs. Adding one digits
  • Implemented by teacher’s aide
  • Completed daily for three weeks
progress monitoring
Progress Monitoring
  • To determine baseline:
    • 3 multiple skills math CBM
    • Probe developed at Intervention Central
    • 2 minutes to complete
    • Scored for digits correct per minute
    • Median score used as baseline
  • To monitor progress: collect data twice a week for three weeks using the same probes
  • Improve Jasmine’s mathematical computation skills by increasing her accuracy and to improve her attitude towards the work itself
  • Increase digits correct per minute by one digit per week
intervention modification
Intervention Modification
  • Change intervention from independent worksheet to working with teacher’s aide
  • Ratio of challenging to easy problems changes from 1:1 to 3:1
  • Continue collecting data twice a week for three weeks
  • Jasmine met her goal
    • Increased digits correct per minute by 7 digits in 6 weeks
  • Improvements
    • Should have specified which method to begin with
    • Used multiple skills CBM
      • Perhaps should have limited this to multiplication and division since these were her problem areas
