Peer reviewed Peer reviewed
Smith, Susan R.; And Others – Journal of Research in Science Teaching, 1981
Study investigated the relationship between children's (N=66) length conservation status and ability to acquire specific length measurement skills, and examined the interaction between mode of instruction (manipulative, graphic, and abstract) and conservation status. The expectation that length conservers would outperform nonconservers on…
