Spatial Thinking In Everyday Life

In March 2003, Mark Wegner and Deborah Girasek published a study in Pediatrics on the readability of printed instructions for car safety seat (CSS) installation. They were motivated by a report that 79 to 94 percent of child safety seats were improperly installed, while 46 percent of accident-related deaths among children aged I to 14 resulted from motor vehicle collisions. Our data indicate that CSS instructions in the United States are currently written at a reading level that is too high.

Experts in the arena of health literacy recommend that materials be targeted to the fifth-or sixth-grade reading level. The average readability level of the instruction sets that we tested was 10th grade. Researchers. found that approximately two thirds of parents tested in an outpatient clinic could not read at more than a ninth-grade level. Because parents would be expected to be the main target for CSS instruction sets, this lends additional evidence that the instruction sets may not be reaching the people most likely to benefit from the message. On the face of it, the study confirms general beliefs about the failure of American education to produce verbally literate people who can read polysyllabic words; the authors used the SMOG (Simple Measure of Gobbledygook) statistic based on the number of three or more syllable words in text samples.

They recommended that "manufacturers of CSS rewrite their instruction sets to a fifth-grade reading level. This could be accomplished by using shorter sentences and simpler words". In the committee's judgment, a second message can be drawn. Wegner and Girasek noted that "This study did not take into account some factors that tend to increase comprehensibility, such as the use of illustrations and empty space." because "Pictures and diagrams were not considered, neither were captions that stood apart from the rest of the instruction set and applied only to pictures". That many car safety seats are improperly installed should come as no surprise to any adult American. The problem is not simply one of comprehension as a function of word complexity, sentence length, and therefore, verbal literacy. Comprehension is a function of another form of literacy, one that is equally essential but largely overlooked.

Spatial literacy lies at the heart of spatial thinking. It was unfortunate that Wegner and Girasek chose not to include the pictures and diagrams because installation instructions are a complex combination of text and graphics. But you should so something useful for yourself in your thinking process. For this part, children might have considerations about how to understand a foreign language, learning a foreign language needs a leaning tools, many children choose Rosetta Stone Russian and Rosetta Stone Spanish to learn Russian and Spanish.
