“Each word shows how you love me”: The social literacy practice of children’s letter writing (1780–1860)

This article draws on hundreds of letters that formed German children’s correspondence with their parents, other relatives, teachers and friends, written mostly between the 1780s and 1850s. Through this study, we see the part literacy played in transformations of bourgeois childhood in eighteenth- and nineteenth-century Europe. The article further investigates how children used letters as a means of learning sociability and building relationships within kinship networks. Historians of education have sometimes treated children’s writing as secondary to more authoritative records. Yet we miss something important about the history of literacy education if we disregard children’s writing or use it only superficially. This article considers the genre of children’s letter writing, exploring the conventions and typical subjects which contributed to the social purpose of correspondence. Letter writing is examined as a paedagogic exercise, including the preoccupation with the medium which filled children’s letters and evidence of instruction in letter writing. It demonstrates that letters fostered the participation of middle- and upper-class children in household affairs, kinship networks and cultural spheres connected through school friends and parents’ acquaintances from very young ages. Children’s correspondence documents a lifelong process in the making of class cultures and forging of social ties.     

Genetic and Environmental Etiologies of the Longitudinal Relations Between Prereading Skills and Reading

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post‐first grade (M = 7.4 years), and post‐fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print knowledge, rapid naming, phonological awareness, vocabulary, and verbal memory) were primarily responsible for relations with word reading and spelling. However, relations with post‐fourth‐grade reading comprehension were due to both genetic and shared environmental influences. Genetic and shared environmental influences that were common among the prereading variables covaried with reading and spelling, as did genetic influences unique to verbal memory (only post‐fourth‐grade comprehension), print knowledge, and rapid naming.     

Cultural sensitivity: American and British teacher trainees compared ‐ a response to Thomas Deering

How effectively are teacher trainees prepared for teaching ethnic minority pupils? What part does practical teaching experience play in developing the cultural sensitivity of trainees? Do American and British trainees differ in their levels of cultural sensitivity and, if so, what are the causal factors involved? This article is a critical response to Deering, who has identified these as his research questions. While welcoming the attention given to an important subject, we question the appropriateness of Deering's research procedure and challenge his interpretation and discussion of the findings.
