Transcript

  • 1. Effective Information Communication to Teens The relationship between electronic reading devices and teenagers’ effectiveness in reading in an academic setting
  • 2.
    • Electronic reading devices are found frequently in use in the academic setting for academic purposes.
    • At Student’s High School
    • 9 new iPads for a social studies class
    • No printed textbooks for non-honors math classes
      • Notes and tests online
    • Electronic journal research in Authentic Science Research Program
    Purpose
  • 3. Background
    • Among Teenagers
    • Reading has declined
    • Much of society shifting to electronic media
      • 33% of kids ages 9-17 ”access to eBooks would increase leisure reading”
      • 57% wanted to read on electronic devices (Scholastic)
    • People likely have preference for one or the other
    Electronic Reading Print Reading Effective transport No screen glare Paper conservation Better adjusted Long-term budget efficiency Tangibility
  • 4. Where µ 1 is the mean score of tests taken on electronic screens. Where µ 2 is the mean score of tests taken on paper. The true mean difference of the mean of the electronic screen test scores and the mean of the paper test scores is equal to zero. The true mean difference of the mean of the electronic screen test scores and the mean of the paper test scores is not equal to zero.

    • Since p< α , 6.94E-22<.05, we reject H 0 in favor of H a .
    • Hypothesis disproven
      • Students read more efficiently on paper
        • Time taken
            • Almost twice as long to read on electronic devices
        • Reading Comprehension
            • Significantly lower scores on electronic devices
      • Backlight affects students’ effectiveness in reading
        • Of electronic reading devices, student performed best on the Kindle, iPad and PC in that order
      • Students prefer reading on paper in an academic setting
    • Students read more effectively through printed reading material than through electronic reading devices.
    Discussions
  • 11. Limitations and Bias
    • Measures taken to avoid bias
      • Randomization of comprehension tests on reading mediums
      • Randomization of testing order
      • All AP Psychology students
          • Must have certain level of reading ability
      • Standardized reading comprehension tests
          • Equal levels of difficulty
          • Both on subjects of history
    • Remaining bias
      • Convenience sample
        • May not be able to generalize conclusions to all populations
      • Lack of prior exposure to electronic reading devices
      • Reading text font sizes
  • 12.
    • Students are not yet ready to change from printed to electronic reading.
      • Though previous studies show that students read more and prefer reading on electronic devices for leisure reading, academic reading is not the same.
      • The switch may result in poorer student performance.
      • Consideration must be given to the impact on students’ reading efficiencies when determining school text material.
    • Future Study
      • Run similar study design with subjects who have learned to read through electronic reading devices.
        • Longer exposure to electronic reading devices may impact results.
