What is the point of telling you about this second book Well, it all hinges on the dates involved. The latter story was written in the early 1960s, whereas the Goosebumps series dates from the 1990s. (46) This makes the point rather dear: The sands have shifted radically in 30 years. A "debunking" book like this is no longer fashionable. Who today wants to read about anything as thought-provoking and "uncool" as debunking Where once a movie was commonplace (47) The "magical realism" movement, where natural and supernatural events happily converge, has become enormously influential in serious literature, as well. Movie and television viewers and readers of serious literature are given the tacit message that me line between the natural and supernatural is blurry, and perhaps even nonexistent.Not surprisingly, concomitant with these high--and pap--culture trends comes a profoundly disturbing collective shift in attitude. (48) The general public no longer views science, let alone the ultimate truths of the universe, with a sense of awe and mystery, but instead considers it conservative and mundane, "trapped" in logical thinking. It is as if the shackles of rigidity have been removed when "open-minded" attitudes are conveyed on television, in books, in movies about ESP, UFQ, or any of a thousand other varieties of alleged paranormal phenomena. (49) The great danger, in my estimation, is not so much that vast numbers of children and adults will get sucked wholesale into truly goofy belief systems, but that they will be misled into accepting the implicit message that science is boring, conservative, dose-minded, devoid of mystery, and a negative force in society. Again, this message is not overt, but tacit, perhaps not even consciously intended. Yet it is precisely this subliminality that makes it so insidious and dangerous.I have no quick fixes. I do not know how to quickly and easily repair decades of damage. I do not even fully understand why the sands have shifted so radically. (50) All I can do is look on in sadness and worry about the future of rational inquiry, bemoaning the loss of awe toward genuine mysteries that our society was once lucky enough to possess.

Though hardly as unwelcome as death or taxes, college entrance exams are just as inevitable and almost as dreaded by high school students.As the testing dates loom for juniors and seniors for the SAT (formerly called the Scholastic Assessment Test) and the American College Test, or ACT, most students are looking for an edge, any edge, in the competition.And as the number of homes with computers continues to rise, test publishers and software developers have been quick to recognize a growing niche. With the market for test preparation materials at all levels estimated at $540 million annually, they have jumped on the tech bandwagon to produce computerized tutorials that promise to boost scores.(41) " We believe that it’s important for a student to be prepared to take the tests, " notes Don Powers, a research scientist at the Educational Testing Service in Princeton, N. J. , the organization that administers the SAT for the College Board. " It’s important to know how to take the test so that you won’t get a score that’s lower than you deserve. " But, he adds, " none of the rigorous scientific evidence that we have seen supports these promises" to raise test scores.(42)Several points, however, do weigh in favor of software as opposed to traditional test-preparation. Cost is a big one.(43)Convenience is another, as the College Board points out in touting its new sofware.A few points to remember when evaluating various test-prep software packages:(44)The exams, though they may seem mystical to the test taker, are not magic and certainly not random. There is little variation in the strategies the programs use to boost test scores because there is little variation in how the test are developed.Largely, what differentiates one program from another is the computer interface, which can make the software more—or less—user-friendly, and such features as automated tracking of student progress.(45)A crash course with test prep software is never an alternative to careful, long-term preparation for taking the exams. Some students are better equipped to respond to the self-paced, self-motivated approach software offers than others, Powers notes.Although parents may be in the market for what they consider " serious " study aids, their children, who are the ones taking the tests, may appreciate the programs that offer a little humor.Finally, as programs frequently point out, the SAT and ACT, while important to college admissions officers, are only one element of a successful college application.[A] A test prep course with a live instructor can cost as much as $700. Test-prep software costs $30 to $80.[B] Most of the programs, in fact, emphasize the importance of " guessing strategies " and eliminating unlikely answers to improve scores. Many students often succeed in exams in this way.[C] Unlike many programs, this one can give you a quick, easy and comfortable way to achieve a high score. Such programs can turn your dream passing exams into reality.[D] " I would rather use the program than take a preparation course, because I could do this on my own time and in my own home, " notes one student in the College Board materials.[E] Although at least one of the test programs asks you how long you have to prepare to take the examination in order to customize the learning curve, all recommend spending a period of weeks, not hours, using the software.[F] But though many programs offer money-back guarantees, professional test writers tend to scoff at those claims. In their mind, such programs overemphasize its functions.[G] SAT and ACT is popular with the international students, especially Asian students. Many Asian students chase their dream through SAT and ACT. 45()
