Teaching the Conceptual Scheme "The Particle Nature of Matter" in the Elementary School.
Pella, Milton O.; And Others
Conclusions of an extensive project aimed to prepare lessons and associated materials related to teaching concepts included in the scheme "The Particle Nature of Matter" for grades two through six are presented. The hypothesis formulated for the project was that children in elementary schools can learn theoretical concepts related to the particle nature of matter. Pretests and posttests were prepared and administered on experimental and control subjects. The statistical procedures employed for assessing the attainment of the concepts are described. A description of reliability and validity of test items is included. The criteria for concept achievement were met by most experimental subjects. The children in grades two through six showed interest in learning about the particle nature of matter. Teacher attitudes about teaching this topic at these grade levels were generally positive.
