    For years attention has been paid to so-called communicative tests – usually implying tests dealing with speaking. More recently, efforts have been made to design truly communicative tests of other language skills as well, such as reading comprehension.

    Canale (1984) points out that a good test is not just one which is valid, reliable, and practical in terms of test administration and scoring, but rather one that is accepted as fair, important and interesting by test takers (the teachers) and test users (the students). Also, a good test has feedback potential, rewarding both teachers and students with clear, rich, relevant, and generalizable information. Canale suggests that acceptability and feedback potential have often been accorded low priority, thus explaining the curious phenomenon of multiple-choice tests claiming to assess oral interaction skills.

    One example of a communicative test has been referred to as a “storyline” test. In such a test, a common theme runs throughout in order to assess the effects of context. The basis for such an approach is that the respondents learn as they read on, that they check previous content, and that the ability to use language in conversation or writing depends in large measure on the skill of picking up information from past discussion and using it in formulating new strategies.

    Swain (1984), for example, developed a storyline test of French as a foreign language for high school French immersion students. The test consisted of six tasks around a common theme, “finding summer employment”. There were four writing tasks (a letter, a note, a composition, a technical exercise) and two speaking tasks (a group discussion and a job interview). The test was designed so that the topic would be motivating to the students and so that there would be enough information provided in order to give the tasks credibility. There was access to dictionaries and reference material, and opportunity for students to review and revise their work. Swain’s main concern was to “bias for best” in the construction of the test – to make every effort to support the respondent in doing their best on the test.

    The Food and Drug Administration warned Wednesday that repeated or lengthy use of general anesthesia or sedation drugs _______ children younger than 3 or pregnant women in their third trimester may affect youngsters' developing brains. The agency, which said its warning is based _________ a comprehensive analysis of the latest research, issued a “drug-safety communication” to inform health-care providers, parents and pregnant women about the risks of using the drugs repeatedly or for more than three hours at a time. It also ordered manufacturers to add warnings to their products labels. “We recognize that in many cases these exposures may be medically necessary,” Janet Woodcock, director of the FDA's Center for Drug Evaluation and Research, said in a statement. The new data on potential harms, she said, “must be carefully weighed against the risk of not performing a specific medical procedure.

    The agency said that laboratory studies show that using the drugs in pregnant or young animals for more than three hours at a time causes widespread loss of nerve cells, which correlated with long-term effects on learning and behavior.

    Some studies have also been conducted in children, with some supporting the findings from the animal research, particularly after repeated or prolonged exposure to the drugs early ____ life. But, all the studies in children had limitations, and the FDA said that “it is unclear whether any negative effects seen in children’s learning or behavior were due to the drugs or to other factors, such as the underlying medical condition that led to the need for the surgery or procedure.” A single, short exposure to the drugs is unlikely to have a negative effect, the agency added. More than 1 million children under age 4 require anesthesia for surgery in the United States each year, for conditions such as congenital heart defects or pyloric stenosis, which is a narrowing of the opening from the stomach into the small intestine.

    The FDA said it has been investigating the effects of anesthesia on brain development since the first animal study on the topic was published in 1999. In 2010, it formed a partnership ________ the International Anesthesia Research Society on a project called SmartTots – Strategies for Mitigating Anesthesia-Related Neurotoxicity in Tots – to fund research on the effect of the drugs on pregnant women and children.
