The source of curriculum development is students. In education or teaching, the learners are students. Education or teaching is not giving something to students or students, but growing potentials that already exist in students. Students become a source of teaching activities, it becomes a source of curriculum. There are three approaches to students as curriculum resources, namely: (a) the needs of students; (b) development; and (c) students interest.The dominant characteristic of a child period that is just learning to walk is activity. Children just learning to walk (toddler) are very busy talking, moving, and planning all the time. The impulse for abundant activity becomes a necessity for self-assertion and mastery. Period from 2 to 4 years, children are aware of their individuality and are motivated to prove it. In this period, toddler must learn to count others in their own discovery. Toddlers change dramatically from ages 2 and 4 from egocentric children who are unaware of dependency on others to become self-aware individual. At first they were very free, but at the end of the age stage, "pseudo freedom" was changed to be more realistic where they depend on others and they are also free from others. In summary, toddlerhood is a period of activity and mastery, self-regulation and the development of an awareness of dependence and freedom.
