States are increasingly interested in including measures of student achievement growth, or "value- added," in evaluating teachers. Annual state assessments, however, which are the typical measure of student growth, usually cover only reading and math teachers and only in grades 4-8. These state assessments thus cannot …

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

A Markov chain Monte Carlo (MCMC) method and a bootstrap method were compared in the estimation of standard errors of item response theory (IRT) true score equating. Three test form relationships were examined: parallel, tau-equivalent, and congeneric. Data were simulated based on Reading Comprehension and Vocabulary tests of the Iowa Tests of…

There is a growing consensus among educators and the general public that technology should play a more integral role in students' education. However, the question of whether the introduction of technology into the classroom has a positive impact on teaching and learning is still under intense debate within the educational community. This…

Adopting a new series of tests can raise student test scores. Scores can also be inflated by ensuring certain students do not take specific tests or by not counting some scores. Dramatic rises in standardized scores are likely to be accompanied by skepticism. (MD)

The major purpose of this study was to ascertain the reading and math progress made by Title I eligible intermediate grade students who lived and attended school in the Minneapolis Public Schools Target Area. A comparison group of students was also selected for study from a non-target school. The study population was all 1969-70 fourth graders…

In 1990-91, the second year of Alaska's statewide testing program, the Iowa Tests of Basic Skills was administered to 24,684 Alaskan public school students in grades 4, 6, and 8. The nationally normed achievement test covered reading, mathematics, and language arts. Most students in grades 6 and 8 scored above the 50th percentile in all subjects,…

The Rasch model was used to compare the grade equivalent scores which students of equal ability would have obtained, had they taken different levels of the Iowa Tests of Basic Skills (ITBS). Raw scores on items common to levels 9-14 of the ITBS (vocabulary subtest) were obtained from 6,000 students in Dallas, Texas. Rasch scales were used to…

Two projects that have explored the feasibility of computer-generated verbal score reports for the Iowa Tests of Basic Skills are reported. The first, the Madison Project, designed, produced, and evaluated computer-generated testing reports that were useful to teachers and informative to parents. The reports, which were narrative in format, were…

The average grade equivalent reading comprehension scores of students in Black schools are compared to those of students in White schools under two forms of test administration. Concludes that use of grade level testing with the Iowa Tests of Basic Skills is biased in favor of low scoring subgroups. (Author)

The purpose of this study was to: (1) compare the book selection preferences of inner-city and suburban fourth and sixth grade children, and (2) determine if children consistently chose books according to categories of literature. Comparison of inner-city and suburban students of the same sex and reading level provided a control for sex and…

Due to a concern regarding the validity of Chicago public elementary schools standardized test scores on the Iowa Tests of Basic Skills, a test audit was conducted. The audit was limited to 40 schools. Two schools were selected from each of the 20 administrative districts, with each school testing one seventh- and one eighth-grade class. These…

Designed for parents of kindergarten and elementary school children in Austin, Texas, this brochure explains the structure and function of the Iowa Tests of Basic Skills. A question and answer format is used to provide information on the scope and purposes of the tests, grade level differences in testing, meaning and accuracy of the scores, and…

Each year all Georgia children and youth in the fourth, eighth and eleventh grades are tested; the Iowa Tests of Basic Skills is used in the fourth and eighth grades, the Tests of Academic Progress in the eleventh grade. Test scores which provide a wealth of information, may be used as a tool for the teacher, principal, curriculum specialist or…
