物理内容标准与考试之间的一致性研究

Alignment between the Physics Content Standard and the Exam

内容标准和考试之间的一致性对社会、学科教学及测验的效度来说都十分重要。我们研究比较了初中物理课程标准和2009年某省中考物理试卷之间的一致性。为了计算两者的一致性指标,我们运用一个共同的结构框架来标记内容标准和考试。结果表明,相对于物理内容标准,考试提高了对认知水平的要求;同时,考试比内容标准更强调＂电＂的知识,所以两者之间的一致性不够。内容标准和考试之间的一致性程度可能影响物理课堂教学。

Alignment between content standards and standardized tests is a significant issue to society, science pedagogy, and test validation. This study compares the alignment between Chinese National Junior Physics Curriculum Standards and Standardized Test of X Province in China in 2009. The same coding framework is used to sign the content standards and standardized tests. It has been found that there is not a statistically significant alignment between them. The insignificant alignment is due to a shift toward higher level cognitive reasoning skills from content standards to standardized tests. The insignificant alignment is also due to a heavier emphasis on ＂electricity＂ in the test than in the content standard. The insignificant alignments may result in desirable and undesirable effects on guiding classroom instruction.
