Mastery learning strategy of teaching is designed by:

Mastery learning is an instructional strategy based on the belief that all students can learn a subject thoroughly if given the appropriate conditions and time.

Key Points

•  The strategy of mastery learning was developed by educational psychologist Benjamin S. Bloom.
• His approach aimed to make learning more effective by ensuring that students master each concept before moving ahead.
• Bloom’s method involves diagnostic pre-assessment, instructional alignment, formative assessments, and feedback.
• His focus was on minimizing learning gaps and promoting equity in the classroom.
• This method reflects his educational philosophy that with proper guidance and time, nearly all students can achieve high standards. Mastery learning forms the core of his broader work on educational objectives and learning outcomes.

 Hint

• J.S. Bruner was known for his work on discovery learning and the spiral curriculum, emphasizing the importance of structure in learning rather than mastery per see.
• Osborne is associated with creative problem solving and brainstorming techniques, not the development of mastery learning.
• B.F. Skinner, not B.S. Skinner, is famous for operant conditioning and programmed instruction, which influenced behaviorist teaching strategies but is distinct from Bloom’s mastery learning model.

Hence, the correct answer is B.S. Bloom.
