Computer simulations were run to measure the relationship between testlet validity and factors of item pool size and testlet length for both adaptive and linearly constructed testlets. Making a testlet adaptive yields only modest increases in aggregate validity because of the peakedness of the typical proficiency distribution. (Author/SLD)

Studies with 220 college students found that multiple-choice test items with 3 items are more difficult than those with 4 items, and items with the none-of-these option are more difficult than those without this option. Neither format manipulation affected item discrimination. Implications for test construction are discussed. (SLD)

Performance of 80 college students on class examinations was studied in relation to self-reported levels of state, trait, and general test anxiety. Data show no relationship between state anxiety and performance. However, general test anxiety was related to examination performance. Test anxious students may not prepare well for examinations.

Measures of reading fluency were investigated as predictors of reading comprehension for 77 third graders and 65 fifth graders. Several of the eight measures investigated were found to be good predictors of comprehension with the potential for use by teachers. Results show that reading fluency is a multidimensional reading construct. (SLD)

Exploratory and confirmatory factor analyses were used to explore relationships among existing item types and three new computer-administered item types for the analytical scale of the Graduate Record Examination General Test. Results with 349 students indicate constructs the item types are measuring. (SLD)

Six-year-olds from Switzerland (n=30) and Argentina (15 middle- and 15 lower-class) were tested for understanding of inequalities between multidigit numbers and place value. Students could explain size relationships better than place value. The three types of children performed differently. (Contains 30 references.) (JAF)

The role played by sex-related differences in prediction of grades from Scholastic Aptitude Test scores with regard to the grade criterion and the variables associated with academic performance was studied for an entire university first-year class (4,351 students). Sources of underprediction for women are discussed. (SLD)

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)

Examined the relationship between the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) IQs and the Kaufman Test of Education Achievement (K-TEA) standard scores, both commonly used in the identification of children for special educational services. Sample consisted of 72 emotionally handicapped children. Results revealed a…

The purpose of this study was to compare the effects of four item selection rules--(1) Fisher information (F), (2) Fisher information with a posterior distribution (FP), (3) Kullback-Leibler information with a posterior distribution (KP), and (4) completely randomized item selection (RN)--with respect to the precision of trait estimation and the…

Recent research links the development of a collaborative community of educators to enhanced teaching and learning effectiveness. This study contributes to this research by testing a work group effectiveness model with a sample of teachers from middle school teams. The study assesses the interrelationships among the model's antecedent variables…

Many topics in chemistry are difficult for learners to understand, including symmetry. Reasons for this difficulty include its multi-level content, instructional methodologies utilized, and learner variables. This study examined the effect of initial instructional modality and prior knowledge on learning of point group symmetry. Forty-four…

Laird studies the relationship between two computerized nursing tests and finds a relationship between the two sets of scores. (Contains 2 tables.)

When 2006 Illinois Standards Achievement Test (ISAT) scores were released in March 2007, there were many questions about the comparability of the 2006 test to earlier ISATs. The 2006 ISAT was a new test, with new items, a new format, new timing requirements, and new scoring procedures. Many people were skeptical about whether it was appropriate to…

There is increasing agreement among those who study classrooms that learning is likely to be most effective when students are actively involved in the dialogic coconstruction of meaning about topics that are of significance to them. This article reports the results of an extended collaborative action research project in which teachers attempted to…
