Abstract

This paper reports the characteristics of a grammar-discourse test which was developed as a subscale of the ATLAN (Adaptive Tests for Language Abilities). ATLAN, which can be used via the Internet, is a collection of sub-scales used to assess different language abilities, mainly in middle childhood. In Study 1, we prepared 67 items from 8 grammar categories for elementary school children and 67 items from 12 grammar categories for preschool children. Participants were 309 children from the first to third grades and 258 preschoolers from 3-6 years of age. One hundred and twenty eight items were chosen based on the results of study 1, as an item pool for a grammar-discourse subscale of the ATLAN. In Study 2, 59 preschool children responded to the two subscales of the ATLAN, grammar-discourse and vocabulary, in addition to the LC Scale (Language Communication Developmental Scale; Otomo et al., 2008). The results of multiple regression analysis, in which the child's score of LC Scale was a dependent variable and the two ATLAN scores were independent variables, showed that 48% of the variance on the LC Scale was explained by the two ATLAN subscales. A discussion focused on the possibility of expanding the ATLAN tests.
