The Effect Of Interleaved Practice In A High School Chemistry Class, Alex Herrington
The Effect Of Interleaved Practice In A High School Chemistry Class, Alex Herrington
Master's Theses & Capstone Projects
Determining practices to produce optimal learning outcomes is a foundational objective for educators. Recent publications have identified the importance of practice sequencing structures (blocked vs interleaved) on learning. While this information has significant value for education, few studies have been conducted in authentic educational environments. This action research involved high school chemistry students (n=25) completing a practice assignment covering mole-mass conversions. One group practiced these problems in a blocked organization while the other was interleaved. Immediately following this assignment, students noted their completion time and rated their perceived difficulty. Three days later, students were given an unannounced interleaved assessment of …

Science, Technology, Engineering, and Mathematics (STEM) Education Faculty Publications
Research has shown that spatial ability plays a key role in understanding STEM (Science, Technology, Engineering, and Mathematics) content, including chemistry. Conservation of Matter (CoM) is an essential but challenging topic for chemistry students of all ages to grasp; it is often taught in a way where students memorize it but do not learn what it means conceptually. This research explored the relationship between understanding spatial ability and conceptual understanding of CoM in middle school students. CoM was examined in two ways using the Conservation of Matter Assessment (CoMA): through questions on conservation of atoms and the conservation of mass. …
