U12B transforms students’ learning by harnessing the power of digital innovations and pedagogical sciences to enable personalised mastery learning so that students overcome the barriers they face in a traditional classroom environment to reach their full potential.

In 1984, educational psychologist Benjamin Bloom found that a mastery learning approach which postulated that students performing in the 50th percentile in a traditional classroom can perform in the 98th percentile with mastery learning plus personalised tutoring. Nonetheless, giving 1:1 tutoring with mastery learning techniques is too costly for most societies to bear in a large scale. Henceforth, the “2-Sigma” problem was born.

Bloom thus challenged researchers and teachers to “find methods of group instruction as effective as one-to-one tutoring”. Bloom classified 4 alterable variables that may have, in combination impact the 2-Sigma problem:

  1. Learner
  2. Instructional material
  3. Home environment or peer group
  4. Teacher

According to Bloom, categorising students as “high” or “low” achievers was almost entirely incorrect. Bloom’s method suggests that the focus of instruction should be the time required for different students to learn the same material and achieve the same level of mastery. This is very much in contrast with classic models of teaching, which focus more on differences in students’ ability and where all students are given approximately the same amount of time to learn and the same set of instructions.

With digital innovations and pedagogical sciences, U12B has effectively resolve the “2-Sigma” problem which educators have been waiting for decades. Personalised Mastery learning is now a reality:

Therefore the challenge becomes providing enough time, quality content and employing instructional strategies so that students will attain mastery.

U12B harness diverse learning methods such as blended learning, self-regulated learning, multimedia interactive learning, pre-learning, group collaboration, embedded A.I. learning, peer learning and virtual classroom to make possible personalised mastery learning. The Bloom’s 2-Sigma problem is resolved.
