The Effects of the Interspersal Procedure on Persistence with Computer-Delivered Multiplication ProblemsKirk, Emily R. 01 August 2010 (has links)
An across-subjects, post-test only design was used in two experiments to assess the impact of interspersing additional math problems (i.e., briefer problems and/or longer problems) among target math problems on students’ persistence when completing computer-delivered math multiplication problems. In Experiment 1, high school students who worked only target problems completed 32% more target problems and worked 22% longer than those who had briefer problems interspersed. Problem completion rates were significantly higher for those who had briefer problems interspersed. These results suggest that altering assignments by interspersing additional, briefer discrete tasks does not always enhance, and in some instances may hinder academic responding. Stimulus preference and within-trial contrast effects provided possible explanations for these results and indicated that interspersing longer problems could, perhaps, cause students to increase persistence. Experiment 2 was designed to replicate Experiment 1 and extend this line of research by investigating the stimulus preference and within-trial contrast hypothesizes.
To increase the number of participants and allow for the evaluation of three conditions, college students served as participants for Experiment 2. In Experiment 2, no significant differences among groups (i.e., control group with only target problems, experimental group with brief problems interspersed, and experimental group with long problems interspersed) were found in the amount of time before college students quit working or in their problem completion accuracy levels. Interspersal of the long problems significantly reduced the number of target problems completed. The results failed to support stimulus preference or within-trial contrast theories.
Discussion focuses on theoretical and applied implications related to the additive interspersal procedure, the discrete task completion hypothesis, and the delay reduction hypothesis. Applied implications suggest that educators avoid interspersing longer discrete tasks and exercise caution when interspersing brief tasks.

The Effect of Explicit Timing on Math Performance Using Interspersal Assignments with Students with Mild/Moderate DisabilitiesHou, Fangjuan 01 May 2010 (has links)
Explicit timing and interspersal assignments have been validated as effective methods to facilitate students' math practice. However, no researchers have explored the combinative effect of these two methods. In Study 1, we extended the literature by comparing the effect of explicit timing with interspersal assignments, and interspersal assignments without timing. Generally, participants' rate of digits correct on easy and hard addition problems was higher during the explicit timing condition than during the untimed condition. However, the participants' rate of digits correct decreased after initial implementation of the explicit timing condition.
Motivation plays a crucial role in maintaining performance levels and helping students make continuous progress. Preferred reinforcers and setting academic targets have been widely utilized as active motivational components to increase the likelihood of a successful strategy in school settings. In Study 2, we employed a brief MSWO reinforcer assessment to identify individual student's low- and high-preference reinforcers and examined the effects of explicit timing on interspersed assignments combined with high preference or low preference reinforcers, and setting academic targets. In general, explicit timing combined with preferred reinforcers and academic targets produced a more sustainable effect on participants' rate of digits correct than explicit timing alone. In addition, high-preference reinforcers were more effective than low-preference reinforcers for three of five participants. For two participants, an increasing trend was observed when low preference reinforcers were contingent on meeting academic targets. These results are discussed relative to using preference assessments with students with mild/moderate disabilities.
