Referenzsemantik in der Partnermodellierung

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.     

Behavioral profiles of children with different levels of achievement

This study examines the relative importance of three behavioral dimensions to reading and mathematics achievement of elementary school children. Previous research on the dimensions which characterize the school behavior of children has shown that these dimensions can be understood as reflecting (a) an adaptation or learning problems dimension, (b) an interpersonal or a social problem dimension, and (c) an intrapersonal or personal adjustment dimension. Scores for each dimension were derived from a cluster analysis of the Pupil Behavior Rating Scale. Based on results of the cluster analysis, subjects were assigned to 12 behavioral typology groups. Analysis of variance showed that behavior typologies were related to both reading and mathematics achievement test scores. Post hoc contrasts revealed that levels of reading achievement are associated primarily with behaviors defined by attributes of the adaptation dimension, and that differences in measures of interpersonal and interpersonal dimensions do not contribute appreciably to group differences in reading and mathematics achievement.     

Methodological considerations in the evaluation of differential components of supplementary education programs

Details procedures to be followed in analyzing multiple program options and time allocation for significant effects. A multiple-option supplementary education program was evaluated by the application of multiple regression analysis as a general data analytic system. One analysis reports the relative merits of supplementary education components when more than one type of program was operated by the same school system and when the criteria for evaluation were end-of-year achievement tests. A second evaluation demonstrates that an analysis of program input variables such as aide time allocation did produce significant improvement in achievement when an analysis of the differential effect of the input variables was considered. An incidental outcome of this study was that significant improvement in reading and mathematics achievement for children in supplementary education programs was more likely to occur with second- and third-grade pupils than with thise at later grade levels.
