This study seeks to determine whether item features are related to observed differences in item difficulty (DIF) between computer- and paper-based test delivery media. Examinees responded to 60 quantitative items similar to those found on the GRE general test in either a computer-based or paper-based medium. Thirty-eight percent of the items were…

The perceived self-efficacy concept plays a significant role in predicting human performance in several areas of human effort, but self-efficacy theory has seldom been applied in the fields of adult literacy and English as a second language (ESL). This study designed a questionnaire for adult literacy and ESL learners to assess their self-efficacy…

This study examined the relationship of multiple-choice and free-response items contained on the College Board's Advanced Placement Computer Science (APCS) examination. Subjects were two samples of 1,000 randomly drawn from the population of 7,372 high school students taking the 1988 examination of the APCS "AB" form. Most were high…

The State Department of Education is releasing the domain specifications of the New Mexico High School Competency Examination (NMHSCE) for educator use because the Spring 1996 administration of the test will be in a different form. The NMHSCE is a high school graduation requirement in New Mexico. It assesses students' competence in writing,…

This manual contains directions for the teacher and oral directions to be read to students taking the practice tests of the Ohio Proficiency Tests for grade 6. Directions are ordered in the sequence of the sections in the Practice Test booklet (writing, reading, mathematics, citizenship, and science), and they are similar, but not identical, to…

The North Carolina End-of-Grade Testing Program is based on the assessment of higher level skills in the context of specific subject-area content. These tests inform students, parents, the community, and educators about the achievement of North Carolina students in grades three through eight in given areas. This report describes the development…

A popular method of analyzing test items for differential item functioning (DIF) is to compute a statistic that conditions samples of examinees from different populations on an estimate of ability. This conditioning or matching by ability is intended to produce an appropriate statistic that is sensitive to true differences in item functioning,…

A major argument against evaluation of teacher performance by students pertains to the instruments being used. Colleges conduct instructional evaluation using instruments they devise, borrow, adopt, or adapt from other institutions. Whether these instruments are tested for content validity is unknown. This study determined how evaluation questions…

Multilog (Thissen, 1991) was used to estimate parameters of 225 items from the Quebec Adaptive Behavior Scale (QABS). A database containing actual data from 2,439 subjects was used for the parameterization procedures. The two-parameter-logistic model was used in estimating item parameters and in the testing strategy. MicroCAT (Assessment Systems…

This teacher's guide contains 11 units of instruction for a course on computer electronics and computer-assisted drafting (CAD) using a personal computer (PC). The course covers the following topics: introduction to electronic drafting with CAD; CAD system and software; basic electronic theory; component identification; basic integrated circuit…

This teacher's guide contains nine units of instruction for a course on computer-assisted pipe drafting. The course covers the following topics: introduction to pipe drafting with CAD (computer-assisted design); flow diagrams; pipe and pipe components; valves; piping plans and elevations; isometrics; equipment fabrication drawings; piping design…

The curriculum for sexually transmitted diseases (STDs) and Human Immunodeficiency Virus (HIV) presented in these two manuals is designed for grades 7-12. Six sections of the student manual, each focused on a particular "STD/HIV Fact," are designed to help young adults learn how to avoid STDs, how STDs are and are not communicated, what to do to…

Current research and learning theory suggest that a hierarchy of proportional reasoning exists that can be tested. Using G. Vergnaud's four complexity variables (structure, content, numerical characteristics, and presentation) and T. E. Kieren's model of rational number knowledge building, an epistemic model of proportional reasoning was…

The phenomenon of simultaneous differential item functioning (DIF) amplification and cancellation and the role of the SIBTEST computer program in detecting it were studied. A variety of simulated test data was generated for this purpose. In addition, the following real test data were used: (1) American College Testing program data for 2,115 males…

The issue of test-item selection in support of decision making in adaptive testing is considered. The number of items needed to make a decision is compared for two approaches: selecting items from an item pool that are most informative at the decision point or selecting items that are most informative at the examinee's ability level. The first…
