Dynamics of the Ly(alpha) and C IV Emitting Gas in 3C 273

This longitudinal study describes playground games of children progressing across their first year of schooling. Boys, in comparison with girls, played more games, especially chase and ball games, and played a greater variety of games. Also, the variety of boys’ games increased across the school year. Girls played more verbal games than boys. The study found that facility with games forecast boys’ social competence and both boys’ and girls’ adjustment to first grade. Children’s groups remained ethnically segregated across the school year. Results are discussed in terms of the role of games as an important developmental task during middle childhood.
