Reported is a study of the teaching and transfer of seriation strategies using non-visual variables with first-grade children. Sixty first-grade children were administered Piaget's stick seriation task and classified as stage I (non-seriators) and stage III (seriators). From this group 24 were chosen and assigned to strategy treatment groups.…

The concept of second language (L2) learning strategies fits well into the theoretical framework of interlanguage. In interlanguage, learning is not defined exclusively with reference to the target language norm, and the use of native language transfer strategies, among other things, is seen as a natural step in the progression toward the target…

The development of a probabilistic model for validating Gange's learning hierarchies is described. Learning hierarchies are defined as paired networks of intellectual tasks arranged so that a substantial amount of positive transfer occurs from tasks in a lower position to connected ones in a higher position. This probabilistic validation technique…
