An Introduction to Cognitive Load Theory

Without an understanding of human cognitive architecture, instruction is blind.

– Dr Vicki Likourezos, The Education Hub (March 3, 2021)


Cognitive load theory helps us to understand how people generally learn and store new information, and the types of instructional practices that best support learning. It draws on the characteristics of working memory and long-term memory and the relationship between them to explain how people learn. Cognitive load theory emerged in the late 1980s from the work of John Sweller and his colleagues. The theory is based on our knowledge of the structure and processes of the human mind, known as human cognitive architecture. Human cognitive architecture helps us understand how we learn, think, and solve problems. It is considered to be a natural information processing system that generates various procedures designed to reduce cognitive load and facilitate the acquisition of biologically secondary knowledge held in long-term memory.

Rethinking How to Promote Reading Comprehension

By Jamie Redcay • January 2, 2026
Rethinking How to Promote Reading Comprehension – Hugh W. Catts (American Educator, Winter 2021–22) It is February 2015, and I am at a national conference listening to a panel present the results of their research on improving reading comprehension. Several members of the panel, like myself and a few others in the room, are funded by the Institute of Education Sciences as part of the Reading for Understanding Initiative. This $120 million program supported six interconnected research teams in their efforts to improve reading achievement in the United States.1 Educators and policymakers had for some time been concerned about the performance of American children on tests of reading achievement. Over the last 20 years, only about a third of students have scored at the proficient level on the reading subtest of the National Assessment of Educational Progress (NAEP).2 This assessment is administered biennially to a representative sample of fourth- and eighth-grade students (and every four years to 12th-graders) from across the nation. Somewhat better, though still troubling, levels of performance have also been reported on state-based reading tests, administered annually starting in third grade. The Reading for Understanding Initiative was intended to jump-start instruction in reading comprehension and significantly improve reading achievement on state and national assessments. In fact, it was described by program officials as the “moonshot” for reading comprehension.

Social Studies Instruction and Reading Comprehension: Evidence from the Early Childhood Longitudinal Study

By Jason Redcay • December 24, 2025
Social Studies Instruction and Reading Comprehension: Evidence from the Early Childhood Longitudinal Study – Adam Tyner & Sarah Kabourek, The Thomas B. Fordham Institute (September 24, 2020) Even as phonics battles rage in the realm of primary reading and with two-thirds of American fourth and eighth graders failing to read proficiently, another tussle has been with us for ages regarding how best to develop the vital elements of reading ability that go beyond decoding skills and phonemic awareness. The dominant view is that the way to improve America’s abysmal elementary reading outcomes is for schools to spend more time on literacy instruction. Many schools provide a “literacy block” that can stretch to more than two hours per day, much of it allocated to efforts to develop reading skills such as “finding the main idea,” and “determining the author’s perspective.” But it doesn’t seem to be working.
