Can blended learning replace conventional learning in terms of mastery learning and cognitive attainment

Blended learning is a pedagogical approach that combines face-to-face learning with online learning. Blended learning is considered as the next conventional learning. So that education in Indonesia is not left behind, the issue of blended learning should have received an appropriate response because in many developed countries many have implemented blended learning as their conventional learning. This research aims to describe whether blended learning is able to replace face-to-face learning as conventional learning today. To describe this, this research was reviewed based on mastery learning and cognitive attainment. Mastery learning is used as a basis for reviewing because education standards in Indonesia use the standard “thorough learning”. The cognitive attainment is used as a basis for reviewing because cognitive levels influence the achievement of critical thinking skills where these skills are one aspect of the basic skills of the 21st century that students must master in this century. This research uses a quasi-experimental method with a non-equivalent design. The population of this research is students of favorite Islamic private elementary schools in Mojokerto. This research concludes that blended learning is able to replace face-to-face learning and is able to influence students’ cognitive attainment.
