Early Childhood Development and Education (ECDE) refer to the care and education services provided to children during their early years. In Kenya it encompasses zero to eight years (both pre- primary and lower primary levels of education). ECDE in Kenya should seek to develop the physical, mental, social, emotional, moral and spiritual and aesthetic dimension of the child. Teachers and care givers should ensure that learning in ECDE centers is holistic, integrated, stimulating and enjoyable. For teachers to do this effectively, they need the knowledge and skills on the ECDE curriculum and its underlying assumptions. This book provides the ECD teacher trainees, teacher educators, practicing teachers and professionals with an understanding on the ECDE curriculum, its planning, design, development and implementation. It draws examples from the ECDE curriculum for Kenya. The course book is recommended for students pursuing diploma and degree courses in ECDE.
