Describes the intellectual development stages ascribed to children by Jean Piaget. Characteristics and examples are given for sensori-motor, preoperational, concrete operational, and formal operational thinking periods. Implications are given for elementary school science education, including (1) formal instruction does not accelerate acquisition…

Piaget's theory of developmental stages was implemented in an elementary school curriculum. Some successful learning experiences are described. (CP)

Some uses of fruits and seeds to facilitate problem solving and cognitive processes in young children are suggested. (MR)

Describes a series of exercises designed to develop student's perceptual skills and to improve the processes of comparing, describing, and developing subsets. Includes suggestions for adapting the exercises into science lessons, providing tips for developing each into complete units. Units include human-made objects, leaves, shells, rocks, and…

Discusses the importance of questioning as a means of achieving independent intelligence, critical thinking, and learning to learn. Advocates a science program that encourages investigation, discovery, and questioning. (MA)

Discusses the applications of Piaget's theory of cognitive development to elementary and junior high school science teaching. Topics include planning concrete experiences, inductive and hypothetical deductive reasoning, measurement concepts, combinatorial logic, scientific experimentation and reflexive thinking. (SA)

Examines childrens' conceptual frameworks and, recognizing that they may be inaccurate, proposes such teaching strategies to aid students in modifying inadequate frameworks as: asking for ideas, listening respectfully, providing guided experiences, and encouraging discussion in non-threatening settings. Stresses learning as an active, thinking,…
