Improving Childrens Understanding of
Units of Measure A Training Study

Measurement
  • Measurement skills lag behind all
    other mathematics topics
    (National Center for Education Statistics, 1996)
  • Particularly difficult
  • Items not aligned with the start of a ruler

  • Development of Training Study
  • Engage spatial thinking during task
  • Use the ruler as a spatial tool

11
  • Children improve on measuring misaligned items
    following training
  • Learning is maintained after a 1 week delay

12
  • Training effectively corrects the counting
    strategy but not the read-off strategy
  • Both groups understood inverse relations and
    correctly used units of different sizes

13
Geographic Learning
  • Using Maps
  • Units of Distance
  • Using scale as measurement
  • Taking into account differences in scale requires
    concept of units
