Investigates possible relations between the methods of quantification available to children and their performance on certain tasks requiring an understanding of number invariance. (Author/RK)

Many studies have confirmed that mnemonic techniques facilitate the acquisition and retention of information. It was hypothesized that, through the reduction of errors in component memory for dimensions (hypotheses, cues, etc.), such techniques should improve performance on conceptual tasks. (Editor)

Suggests that, in undertaking the investigative process, we follow a common path that leads us, through the recognition of present patterns, to the generation of new ones. Schools should have series of goals that become indistinguishable in the light of total human experience. (Author/RK)
