As of May 2015, reviews of Khan Academy math programs are mixed. Common Sense Media gives them four-out-of-five ratings for both quality and learning. A 2012 article in Education Week is more critical, stating that the programs emphasize procedure and facilitate little conceptual understanding.
Khan Academy's math videos are best suited for 12-year-olds, according to Common Sense Media. The segments are useful for school assignments, test preparation and individual exploration. The site emphasizes how to do mathematical operations rather what the concepts are. Critical thinking is not stressed. Programs are moderately engaging and provide a great deal of support and feedback to learners.
Although knowing procedures is important for students, understanding the underlying ideas is especially crucial, states Education Week. Khan Academy does not spend significant time on concepts. The programs focus on memorizing processes. In addition, some episodes have mathematical errors, terminology mistakes or inconsistencies. However, the Academy is working to address some issues and improve their products.
Within the field of mathematics, the Khan Academy seeks to present information for students from kindergarten through calculus, the organization's website explains. In addition to math, Khan Academy provides learning experiences in subjects such as science, computer programming, history, art history and economics.
