Background: When learning causal relations, completing causal diagrams enhances students' comprehension judgements to some extent. To potentially boost this effect, advances in natural language processing (NLP) enable real-time formative feedback based on the automated assessment of students' diagrams, which can involve the correctness of both the…

Inclusive special needs education is prominent on the international education agenda. Research on the characteristics of inclusive education for students with special needs and schools providing this is scarce, however. Our aim in the present study was therefore to further theory-building with regard to inclusive special needs education. On the…

The current study explored the size, stability, and consistency of school effects, using 2 effectiveness indicators: achievements of students at the end of primary school and growth in achievement across 3 years of schooling. The sample consisted of the scores of 25,269 students on 3 subjects, taken in Grades 4 to 6 among 3 cohorts in 319 primary…

Children's peer relationships are frequently assessed with peer nominations. An important methodological issue is whether to collect unlimited or limited nominations. Some researchers have argued that the psychometric differences between both methods are negligible, while others have claimed that one is superior over the other. The current study…

At the Educational Research Centre (S.C.O.) in Amsterdam, a study determined the applicability and construct validity of ratings of speaking performances by examining tape-recordings of subjects in four dimensions. Subjects were 200 pupils of 11 and 12 years of age, and performances on four different oral tasks were investigated. The rating…

A technique is presented to transform incomplete categorical data into complete data by imputing appropriate scores into missing cells. A solution of the optimization problem is suggested, and relevant psychometric theory is discussed. The average correlation should be at least 0.50 before the method becomes practical. (SLD)

Lexical-decision studies with experienced English and French readers have shown that visual-word identification is not only affected by pronunciation inconsistency of a word (i.e., multiple ways to pronounce a spelling body), but also by spelling inconsistency (i.e., multiple ways to spell a pronunciation rime). The aim of this study was to…
