Research has demonstrated the positive effects on reading achievement measures when content is conditioned as a reinforcer for prolonged reading. While previous research has focused on conditioning narrative texts on the relation to increased comprehension, there is no current research on the effects of conditioning informational texts. Experiment 1 examined whether the effects of conditioning narrative texts as a reinforcer extends to technical writing for science, technology, engineering, and math (STEM) content for third graders with and without Individualized Education Plans. We replicated the conditioning procedures used with elementary-aged participants in previous studies for narratives texts. Using a four-step, peer-collaborative procedure, peer interactions were paired with reading activities to condition narrative texts as reinforcers for prolonged reading. Results indicated that reinforcement value of conditioned narrative texts did not transfer to STEM texts. Experiment 2 examined whether the effects of conditioning STEM texts as reinforcer extends to narrative texts. Academic achievement was also measured after conditioned reinforcement for STEM texts was established using the four-step peer collaborative procedure. Results indicated that the reinforcement value for STEM texts did not transfer to narrative texts. [The dissertation citations contained here are published with the permission of ProQuest LLC.
