Effect of Acquisition Rates on Off-Task Behavior with Children Identified as Having Learning Disabilities

Abstract

Research has consistently demonstrated the importance of providing an appropriate level of challenge, called the instructional level, within curricular material. Although the instructional level is a generally well-defined and researched construct, much less data exist on the acquisition rate (AR) component of an appropriate level of challenge. The current study used curriculum-based assessment to assess the AR of five fourth-grade students diagnosed with a reading disability and taught each 20 words from the Esperanto International Language over two sessions (10 each session). Students were observed during instruction, and the number of demonstrated off-task behaviors was converted to a mean rate of off-task behaviors/minute. Comparison of pre- and post-AR data showed that each student demonstrated an increase in off-task behaviors while rehearsing the word that immediately exceeded his or her AR. Implications for practice and suggestions for future research are discussed.
