Before the Education for All Handicapped Children Act of 1975 (EHA) and its focus on provid- ing services in the least-restrictive environment, one million of the children with disabilities were excluded entirely from the public school system and did not go through the educational process with their peers [Sec- tion 601c (2C)].... ..."

Results presented in columns (1), (2) and (4) of Table6 indicate that beneficial effects... In PAGE 21: ...Corresponding p-values are .408 and .114. In columns (1) and (2) of Table6 , only one interaction term is added to the corresponding Table 4 regressions and the relevant test statistic is the t-ratio presented in Table 6. 11 This result runs somewhat counter to Fraas (1982), who reports that better students learn more from lectures, while worse students learn more from simulation-gaming....

"... In PAGE 2: ... The corpus was manually annotated with a set of tutorial dialogue acts designed to capture the salient characteristics of task-oriented tutorial dialogues. The coding scheme ( Table2 ) draws on a scheme devised for tutorial dialogue on qualitative physics problems [10]. While most of the acts in this scheme are present in the Java corpus as well, the particular dialogues in the Java corpus made it difficult to make judgements about short answer questions versus deep answer questions and to make fine-grained distinctions between hinting levels.... ..."

Each query is assigned a unique DA label drawn from a well-defined set (see Table1 ). Thus DAs can be thought of as a tag set that classifies queries according to a combination of pragmatic, semantic, and syntactic criteria a6 .... In PAGE 3: ... Queries are classified into two general categories, question and statement, which are again sub-categorized into primary or secondary, each of which consists of several DAs. As a whole, thirty domain-independent DAs are defined as in Table1 . These DAs enrich the available input for matching a query with a response....

Only one DA is assigned to the query in case of primary question or statement whereas several DAs are assigned to a query in case of secondary question or state- ment.
