Cognitive load theory (CLT) has driven numerous empirical studies for over 30 years and is a major theme in many of the most cited articles published between 1988 and 2023. However, CLT articles have not been compared to other educational psychology research in terms of the research designs used and the extent to which recommendations for practice are justified. As Brady and colleagues found, a large percentage of the educational psychology articles reviewed were not experimental and yet frequently made specific recommendations from observational/correlational data. Therefore, in this review, CLT articles were examined with regard to the types of research methodology employed and whether recommendations for practice were justified. Across several educational psychology journals in 2020 and 2023, 16 articles were determined to directly test CLT. In contrast to other articles, which employed mostly observational methods, all but two of the CLT articles employed experimental or intervention designs. For the two CLT articles that were observational, recommendations for practice were not made. Reasons for the importance of experimental work are discussed.

Guided notes were introduced decades ago, but there is still debate over their efficacy in improving student outcomes. The purpose of this study is to examine peer-reviewed research on guided notes for adult learners in general populations since 2009, understanding the effects of guided notes on student learning, the knowledge and content areas supported by guided notes, and the impact of modality. Results of the 22 included studies indicate that students perceive guided notes in a positive light, and guided notes improve results in certain knowledge domains especially with complex content. However, modality does not influence the efficacy of guided notes. Implications for practice in teaching and learning and recommendations for research were provided.
