This study expands upon an existing model of students' reading comprehension ability within an intelligent tutoring system. The current system evaluates students' natural language input using a local student model. We examine the potential to expand this model by assessing the linguistic features of self-explanations aggregated across entire…

This paper discusses the use of simple sentence-combining exercises as a way to show students the unlimited capacity of their own language. Using sets consisting of eight, six, four, and three sentences, no two students of the 27 in a freshman composition class produced identical rewrites of any one set. Such exercises are useful for instilling a…

In a study extending and refining Carol Chomsky's research, 48 Arabic speaking children aged six, eight, and ten were tested for their comprehension of imperatives using the complement-requiring verbs Ask, Tell, and Promise. Clear support for children's overgeneralization of the minimal distance principle was found only with Promise constructions.…

A study examined the idea that linguistic competence and linguistic performance may be initially dependent on a substrate of imagery. The study explored the ways in which four student interviewees' talk indicated the visual processes of thinking. The prompt used was: describe some aspect of daily life at the age of 9 or 10. The study reviewed…

This paper reports on a study conducted to determine the abilities of children to make optional transformations in sentences conjoined with "and." The subjects were 35 middle-class children between the ages of five and eight, who demonstrated average school achievement, spoke standard American English, and had normal speech and hearing. A…

An investigation of the relationships between form and comprehension of written materials by eleventh grade students is reported in this paper. Students were asked to manipulate two variables of spacing and punctuation in a consistently administered and marked exercise. Students also completed a comprehension test on the exercise they had just…

The relationship between writing skills development and cognitive development is the focus of numerous research studies and deserves significant consideration in curriculum planning. Writing development studies indicate that as children work through the various modes of discourse (argumentation, exposition, narration, and description), they…

This discussion is based on the results of an earlier experiment in which four groups of deaf subjects, ranging in age of first exposure to signing from birth to over eighteen, were given lists of sentences in American Sign Language to shadow and recall immediately after presentation. It was found that in terms of overall accuracy, early learners…

The interview techniques developed by Carol Chomsky were used in a comparative study of the language acquisition of 32 bilingual and monolingual third grade students. After these students were matched for age, socioeconomic status, IQ, family environment (both parents in the home), and reading ability, they were placed in four…

The purpose of this study was to examine the effects of varying the semantic content of active and passive sentences along a dimension of "personalness" on the comprehension of those sentences by preschool age children. The study focuses on a current linguistic controversy dealing with the relative adequacy of syntax-based and…

Previous studies dealing with the age at which children acquire constituent order preferences have been in conflict. This study was designed to determine if children with normal language development demonstrate constituent order preferences as early as age three and one-half, or a mean age of four years, one month. To test this competency, an…

The acquisition of the metalinguistic abilities involved in ambiguity detection and resolution was studied with children. It is suggested that metalinguistic abilities may serve as potential test measures for facility in learning a second language. School children (ages 3, 5, 7, 9, 11, and 13) were tested for their ability to detect ambiguous…

In order to investigate the development of word-formation abilities, 3-, 5-, and 7-year-olds were asked to act out with toys, judge, and make up sentences containing instances of class extension. Some sample sentences are "Can you upside-down the clown?" and "Broom the spoon." Children dealt with such sentences in much the same…

Child acquisition of Mandarin was studied with four middle class families from Taipei, Taiwan. The 2-year-olds were taped at home playing with their families. Two of the children were taped for short periods (7 hours and 9 hours), while the other two children were studied biweekly for 14 months, which resulted in 71 hours of transcribed child…

Three empirical studies were conducted to investigate the hypothesis that the "easy to see" construction (such as in the sentence "children are hard to understand") is acquired at a younger age than the 7-9 year range reported by previous studies (Cambon and Sinclair, 1974; Chomsky, 1969; 1972; Cromer, 1970; Kessel, 1970).…
