Analyzing and discussing solved problems helps students develop a deeper understanding of abstract mathematical processes. Worked problems reduce the cognitive load for students, as they do not have to solve the problems themselves but can instead focus their Attention on understanding and comparing different solution methods. Interleaving practice problems with worked examples can push students to monitor their thinking when solving problems, building Metacognition.
Videos are chosen as examples of strategies in action. These choices are not endorsements of the products or evidence of use of research to develop the feature.
Videos are an excellent way to provide worked examples for students to study, such as this example on doing Operations with fractions. Products can easily integrate such videos into their instructional roadmap, supporting students' deeper conceptual development.
