Executive SummaryFive States Take the Lead in Science Score Gains Compared to middle and high school students, younger students are making the most progress in science. In 2005, a representative sample of more than 300,000 students in grades 4, 8, and 12 was assessed in science. This report presents national results for all three grades, and state results for grades 4 and 8. The 2005 results are compared to those from 1996 and 2000. Sample questions are presented to illustrate the types of skills and knowledge that were assessed at each grade. * Significantly different from 2005. At grade 4, the average science score was higher in 2005 than in earlier years. The percentage of students performing at or above the Basic achievement level increased from 63 percent in 1996 and 2000 to 68 percent in 2005. An example of the knowledge associated with the Basic level is identifying two organs in the human body that work together to supply oxygen. Twenty-nine percent performed at or above the Proficient level. Relating the amount of time a candle burns to the amount of air available is an example of the knowledge and skills at the Proficient level. At grade 8, there was no overall improvement. In 2005, 59 percent of students scored at or above the Basic level. An example of the knowledge and skills at the Basic level is being able to compare changes in heart rate before, during, and after exercise. Twenty-nine percent performed at or above the Proficient level. Identifying the energy conversions that occur in an electric fan is an example of the knowledge and skills at the Proficient level. At grade 12, the average score declined since 1996. In 2005, 54 percent of students scored at or above the Basic level. Knowing the function of a neuron is an example of knowledge at the Basic level. Eighteen percent performed at or above the Proficient level. Identifying the source of heat energy released in a combustion reaction is an example of knowledge at the Proficient level.
Minority Students Are Making Gains at Grades 4 and 8Minority students in grades 4 and 8 are making progress. At grade 4, average scores increased by Score Gaps Narrowed Between Younger White, Black, and Hispanic StudentsDue largely to gains made by minority students, the score gaps between fourth-grade White students and their Black and Hispanic peers were smaller in 2005 than in 2000. The gap between White and Black students narrowed by 4 points since 2000, while the gap between White and Hispanic students narrowed by 8 points. The gap between White and Black twelfth-graders, however, widened during the same time period.
