Curriculum: Meaning and Principles

                                                                            Curriculum Meaning:   The word "curriculum" is derived from the Latin term "currere," meaning "race   course," signifying a path or course to be followed in order to reach a specific goal. In education, the curriculum encompasses far more than just the subjects of study—it is the sum of all experiences a student undergoes throughout their schooling. This includes classroom learning, laboratory exper iences , workshops, playground activities, club involvement, co-curricular pursuits, and informal interactions between teachers and students. Essentially, the entire school environment forms the curriculum, contributing significantly to the holistic development of a child’s personality and preparing them for a meaningful...

Types of Curriculum

  Types of Curriculum 1. Learner-Centered Curriculum The National Policy on Education (NPE) 1986 and its revised NPE, 1992 emphasized the importance of child-centered or learner-centered education. Modern education follows a child-centric approach, where the learner is at the core of all educational activities. This curriculum is designed around the physical, mental, emotional, and social needs of the child. Educational philosophers such as Montessori, Rousseau, Pestalozzi, John Dewey, Froebel, Mahatma Gandhi, and Tagore were key advocates of learner-centered education. Features/Characteristics: 1.  The primary aim is the holistic development of the child's personality. 2.  It emphasizes the child's experiences—nothing is forced upon the learner without ensuring their understanding. Learning is tailored to the child’s preferences and comprehension. 3.  The curriculum is life-related, meaning it focuses on subjects and activities that are relevant to the child's life ...

Mastery Learning

  Mastery Learning Mastery learning  is an instructional approach designed to ensure that all students achieve a level of mastery in the subjects being taught. It originated with educational theorists such as Johann Heinrich Pestalozzi  and John Amos Comenius , but the modern concept was popularized by Dr. Benjamin S. Bloom  in 1968. Bloom emphasized the combination of teacher tutoring  and individualized instruction , ensuring that students can master learning objectives at their own pace with proper feedback and remediation. In a mastery learning framework, the belief is that with enough time and the right instructional support, every student can achieve mastery over a subject. Instead of moving on when only some students have grasped the content, mastery learning provides time for re-teaching, feedback, and corrective activities, ensuring all students meet the required level of understanding. Procedure or Steps in Mastery Learning: 1.  Stating Behavioral...
