Nicotine replacement therapy (NRT) repeatedly has been shown to improve smoking treatment outcome. The major mechanism posited for this improvement in outcome is that NRT reduces nicotine craving and withdrawal. The authors tested this hypothesized mechanism of action using real-time data on craving and withdrawal, collected by ecological…

We assessed choices on a computerized test of self-control (CTSC) for a group of children with features of attention deficit hyperactivity disorder (ADHD) and a group of controls. Thirty boys participated in the study. Fifteen of the children had been rated by their parents as hyperactive and inattentive, and 15 were age- and gender-matched…

Educators in Europe are complaining about mishandled changes in a key English-language test and are demanding that the Educational Testing Service (ETS), which runs the examination, delay plans to introduce its new online format in March 2006 in more than 100 countries. Critics of the planned change in the Test of English as a foreign Language…

Developed jointly by OECD member countries through the OECD's Directorate for Education, the Programme for International Student Assessment (PISA) aims to measure how far students approaching the end of compulsory education have acquired some of the knowledge and skills essential for full participation in the knowledge society. The assessment is…

To assess own actions and define individual learning needs is fundamental for professional development. The development of self-assessment skills requires practice and feedback during the course of studies. The "Interactive Examination" is a methodology aiming to assist students developing their self-assessment skills. The present study…

Many researchers have investigated the effects of students' prior knowledge upon learning chemistry, for example, the tenacity of alternative conceptions. Knowledge about learning also shapes students' learning of chemistry. This research describes the development of CHEMX, a survey instrument that measures an aspect of knowledge about learning…

Recent research studies have reported on how novices and experts differ in storing, organizing, and retrieving subject matter knowledge and on how they apply their knowledge to solve new problems. These findings have been integrated and implemented in a computer environment to help novices improve their problem-solving skills. An outline of this…

This report contains results of a field test conducted to determine the relationship between a Graduate Records Examination (GRE) linear computer-based test (CBT) and a paper-and-pencil (P&P) test with the same items. Recent GRE examinees participated in the field test by taking either a CBT or the P&P test. Data from the field test…

This Monte Carlo study examined the effect of complex sampling of items on the measurement of differential item functioning (DIF) using the Mantel-Haenszel procedure. Data were generated using a three-parameter logistic item response theory model according to the balanced incomplete block (BIB) design used in the National Assessment of Educational…

This paper presents preliminary, but statistically significant, findings from a study that compares two methods of measuring instructional effectiveness: global evaluation by experts and systematic observation using the SCRIBE Ob.2 software developed at the University of Texas at Austin. Hierarchical instruction of a performance skill…

Research has produced mixed results in evaluating whether people are influenced more by computer output than by other information. The present study examined how teachers' perceptions of psychological reports differ when the reports are identified as being produced by a computer program or by a school psychologist. Subjects were 40 experienced…

The integration of test-banks for computer-based testing, textbooks, and electronic lecture notes in first-year mathematics courses has changed the way mathematics is taught at Bennett College (Greensboro, North Carolina). Classes meet in two electronic classrooms each with 27 computers on a local area network and a projection system. An…

Thousands of older incarcerated youth (17-18 years old) pass through the juvenile justice system every year. Many are not viable candidates for traditional high school graduation because of limited earned credits and large gaps in education. The purpose of this study was to establish an effective and efficient means for determining students'…

Computerized adaptive (CA) testing uses an algorithm to match examinee ability to item difficulty, while self-adapted (SA) testing allows the examinee to choose the difficulty of his or her items. Research comparing SA and CA testing has shown that examinees experience lower anxiety and improved performance with SA testing. All previous research…

The Grammar, Spelling, and Punctuation (GSP) test is administered to students in the College of Communication at the University of Texas, Austin, as a means of determining eligibility to register for certain courses in journalism, broadcasting, and advertising. The test was administered in a paper-and-pencil version to 16 students and in a…
