This project seeking to develop sound methodological research techniques for second-language is based on an initial pilot study which (1) identified and classifies the utterances of a child learning Spanish as a second language, and (2) determines whether there are any significant trends in the observed order of learning of kernels and transformed sentences. During a second year of research six children between five and six-and-a-half participated in an expanded version of the experiment concerning language acquisition which concentrated on the description and classification of the linguistic utterances produced by the subjects. Major chapters include: (1) introduction, (2) research design, (3) noun phrase, (4) verb phrase, (5) imperative, (6) interrogative, (7) sentence compounding and embedding, and (8) conclusions and implications. A bibliography and a list of linguistic diagrams are included. (RL)
