There are 15 testlets, each containing 5 items, associated with each passage. Each testlet requires students to demonstrate various levels…

In response to the tradition of examining a new test's validity by comparing it with a well-established multiple-choice test, a study investigated whether multiple-choice tests with one right answer can measure the reading comprehension process as defined by constructivists. The study compared the information obtained from two different…
