This booklet contains four articles that discuss factors influencing language growth. The first, "The Child's Equipment for Language Growth" by Charlotte Wells, examines what the child needs for language learning, how the child uses his equipment for language growth, and what school factors facilitate the child's use of his equipment for language growth. The second article, "Home Influences" by Dorothea McCarthy, examines individual differences in language at school entrance, babbling in infancy, mother-child relationships and speech problems, home atmosphere, bilingualism, interdependence of home and school atmospheres, language disabilities, and remedial work. The third article, "School Influences" by Ruth G. Strickland, examines the teacher, the peer group, the school environment and atmosphere, and the interrelationships among the language arts. The last article, "Community Influences" by Muriel Crosby, examines the community as a school laboratory for language growth, modern media of communication, and the influences of church, library, and summer camp on children's language growth.
