The content of the Science Test includes biology, chemistry, physics, and the Earth/space sciences (for example, geology, astronomy, and meteorology). Advanced knowledge in these subjects is not required, but background knowledge acquired in general, introductory science courses is needed to answer some of the questions. The test emphasizes scientific reasoning skills over recall of scientific content, skill in mathematics, or reading ability.
The scientific information is conveyed in one of three different formats:
· Data Representation (38%). This format presents graphic and tabular material similar to that found in science journals and texts. The questions associated with this format measure skills such as graph reading, interpretation of scatter plots, and interpretation of information presented in tables, diagrams, and figures.
· 数据表示(38%)和科技杂志和文章一样,以图形和表格的形式来表述信息。考察学生图表阅读,分散图的解读,对表格,图表和数字形式信息的理解。
· Research Summaries (45%). This format provides descriptions of one or more related experiments. The questions focus on the design of experiments and the interpretation of experimental results.
· 研究概述(45%)提供多个相关的试验,问题强调对于试验设计和试验结论的解读。
· Conflicting Viewpoints (17%). This format presents expressions of several hypotheses or views that, being based on differing premises or on incomplete data, are inconsistent with one another. The questions focus on the understanding, analysis, and comparison of alternative viewpoints or hypotheses.
· 矛盾观点(17%)以几个基于不同的前提和假设、基于不完善的数据的互不一致的观点,着重强调对不同观点的理解、分析和比较。
