This paper investigates the effect of teacher quality, represented by teacher level characteristics, on mathematics gain scores employing multilevel (or three-level hierarchical linear model, HLM, based) unconditional and conditional value-added model (VAM). We found the significant effects of teacher's mathematics content certification, teacher…

Evaluation of attributes of a subcompact car were combined in linear regressions predicting liking and purchase intention. Of two forms--raw scales and scales weighted by the importance attached to each attribute by each subject--unweighted evaluations proved more consistent and important predictors than those weighted by their saliency.

The aim of this study is to suggest an alternative to the essay testing method of assessing structural understanding of concepts, which suffers from time constraints and lack of scoring reliability. In this method, students' relationship judgments between concept pairs are examined directly rather than by means of multidimensional scaling analysis…

A study provided the initial test of a multidimensional instrument based on the idea that syntactic language choice might predict writing apprehension. The test measured six factors: (1) blank page paralysis, (2) general affect toward writing, (3) positive/negative business affect, (4) alternative modes, (5) attitude toward writing competence, and…
