Obama started the fair as a way to highlight and encourage STEM education.
But California eighth-grade scores rose 3 points from 2011, their last test, and fourth-grade scores rose 4 points from 2009, their last measurement.
The gap between Hispanic and white students has shrunk for both fourth- and eighth-grade science compared to 2009.
The results of last year's National Assessment of Educational Progress suggest a renewed focus science in education, specifically to get girls more excited and involved in the subject, is having a good effect on younger students as their scores showed statistically significant improvement. The 12th grade exam provided only national results, so there were no separate marks for high school seniors in Florida or the other 45 states that took part in NAEP science previous year.
State officials on Wednesday maintained the tests can not be accurately compared. The science results are reported on a 0-300 scale. Additional data was provided voluntarily by 46 states and the Department of Defense (DOD) school system for fourth and eighth grades. White fourth-graders scored an average of 33 points higher than black students and 27 points higher than Hispanic students. "Without a strong education in these vital disciplines, our nation can not compete in a global economy".
Peggy Carr, acting commissioner for the National Center for Education Statistics, also highlighted achievement gains in her comments - even though more than half of tested students in almost all the states scored below proficient.
Gov. Bill Haslam and astronaut Barry Wilmore - a Mt. Juliet native - are touring the state Thursday to celebrate Tennessee's latest achievement: soaring scores in science proficiency.
The state's fourth graders beat the national average and eighth graders kept pace with it, both improvements from 2009.
Pak govt bans protests in Islamabad, Imran Khan remains defiant
It directed that the district administration should designate a specific place for the Pakistan Tehreek-e-Insaaf public meeting. He added, "The fundamental rights of the common man can not be compromised in the name of protest".
The vast majority of US students still lack a solid grasp of science despite some modest gains by fourth and eighth graders, especially girls and minorities. Butch Otter's office. The center's main effort in 2016 is the launch of a new state computer science initiative. Average scores for fourth-grade students increased 4 points since that time.
"Science at elementary schools is minimal at best, and non-existent in some places", Barbara said.
Parents and teachers have long anxious that schools under pressure to raise math and reading test scores are narrowing the curriculum, excluding science and social studies. Education reform advocates say that even the highest scores demonstrate, at best, that only half the students are proficient in science. It's not clear whether or how much that contributed to the gains, she said.
Nationally, the test results showed that 38 percent of fourth-grade students were considered proficient or above in science.
NAEP scores, which are being released publicly today, show that the vast majority of New Mexico's fourth- and eighth-graders did not reach the benchmark in science, with a large percentage landing in the lowest scoring category, "below basic".
NEAP did not provide district-level results.
Racial score gaps have improved nationally for all groups except American Indian/Alaska Native 8th graders since tests were last given. Those results show roughly 60 percent of both fifth- and eighth-graders taking the test were proficient.
High standards have always been characteristic of NAEP, which calls itself the "nation's report card" because it has always been the only way to compare students across states.
"This is exactly what we would like to see - all students improving but students at the bottom of the distribution making faster gains", Carr said.
