The current research was an attempt to explore the washback impact of task-based instruction (TBI) on EFL Iranian learners' vocabulary development. To this end, conducting an Oxford Placement Test (OPT), 30 out of 72 EFL Iranian learners studying in an English language institute, were randomly selected. Then, they were assigned to experimental (N…

There has been an increased level of attention devoted to the consequences of test use in recent years; however, the majority of washback studies focused on teaching. In fact, little research has addressed learners' perspectives to analyze possible determinants of test results. To address this issue, this study first compared the pre-and-post…

Simultaneous with a call for standardized assessments to assess developing rather than preexisting or surface knowledge (Sawyer, 2006) has been a growth in awareness of the unavoidable interactive nature of any form of assessment and this awareness has created a social turn towards approaches to language assessment (McNamara & Roever, 2006).…

The study aimed at investigating TOEIC score distribution patterns and learner satisfaction in an intensive TOEIC course and drew implications for pedagogical practice. A one-group pre-test post-test experiment and a survey on learner satisfaction were conducted on Taiwanese college EFL students (n = 50) in a case study. Results showed that the…

A computer simulation procedure was developed to reproduce the overall pattern of results obtained in the Educational Testing Service Growth Study. Then simulated data for seven sets of 10,000 to 15,000 cases were analyzed, and findings compared on the basis of correlations between estimated and true growth scores. Findings showed that growth was…

A new testing strategy that provides protection against the problem of having examinees in adaptive testing choose difficulty levels that are not matched to their proficiency levels was introduced and evaluated. The method, termed restricted self-adapted testing (RSAT), still provides examinees with a degree of control over the difficulty levels…

In computerized adaptive testing (CAT), new or experimental items are frequently administered alongside operational tests to gather the pretest data needed to replenish and replace item pools. The two basic strategies used to combine pretest and operational items are embedding and appending. Variable-length CATs are preferred because of the…

Pretesting not only helps determine the benefits of a training program, it can actually help trainees learn more. (Author/SSH)

Confidence Weighting (CW), after Ebel, and Multiple Responding (MR), after Coombs, are compared empirically to determine which improved test reliability more in the case of a course pretest derived from the final examination. It was hypothesized that MR, which purportedly measures partial knowledge, would be more effective than CW, which measures…

A pretest-posttest design for measuring the effects of educational programs uses comparison groups consisting of pupils like those in the treatment group but not getting that particular treatment. Although the design is geared primarily to evaluation of Title I programs in large cities, it should also apply to other situations. The plan for…

In recent years, assessment of what is actually learned or accomplished in a college career has gained increasing attention. An instructor of a weather and climate geography course at Illinois State University constructed a 25-question multiple choice test in order to develop a method of assessing what his students learned during the course. The…

In spring 1986, new citywide testing programs in both reading and mathematics were implemented by the New York City Board of Education. In those cases where the test had changed, it was necessary to statistically equate the new tests to the old tests, so that comparisons of equated rather than actual scores could be made during the transitional…

During a three-year project (1977-1980) on computerized adaptive achievement testing, item characteristic curve theory (ICC) and adaptive testing strategies designed almost exclusively for ability testing were applied to achievement testing. Adaptive techniques substantially reduced test length without reducing quality, when applied to three…

The Title I Evaluation and Reporting System (TIERS) was developed in order to examine the extent to which Title I (now Chapter 1) is remediating the disadvantages in basic skills of educationally deprived children. TIERS Model A contrasts the achievement of Chapter 1 students to publishers' norms for hypothetically comparable groups of students.…

A study was conducted to determine if the observed changes in Head Start children were related to the practice effects inherent in a test-retest situation. The "control" group consisted of 64 children who had been eligible for a Head Start program. They roughly matched a group of Head Start (HS) children in IQ scores, age, and…
