Background: Undergraduate STEM instructors want to help students learn and retain knowledge for their future courses and careers. One promising evidence-based technique that is thought to increase long-term memory is spaced retrieval practice, or repeated testing over time. The beneficial effect of spacing has repeatedly been demonstrated in the…

Time delay is one of the most established practices for teaching both functional and academic skills to students with extensive support needs (ESN). Students with ESN have intellectual or developmental disabilities and, in some cases, other support needs (e.g., physical disabilities, sensory impairments) and require comprehensive instructional and…

The present study evaluated the use of computerized equivalence-based instruction (EBI) to teach classes representing schedules of reinforcement to staff members. Four, 5-member classes representing fixed ratio, fixed interval, variable ratio, and variable interval schedules of reinforcement were taught. The participants were 16 staff members…

This study assessed the efficacy of the spaced learning method compared to the activity-oriented method in improving chemistry achievement among high school students, focusing on different cognitive domains. An experimental design involving pre and post-test control groups was employed, with 106 students from two schools participating. The…
