A new national assessment that examines how well students are learning science shows that California is among the lowest-performing states as measured by average test scores.

“The Nation’s Report Card: 2015 Science,” released Thursday by the National Assessment of Educational Progress, included scores from 46 states that measured the progress of 4th- and 8th-graders over six years through 2015. The 4th-graders in 43 other states and the 8th-graders in 41 states had higher scores than their California counterparts.

Despite struggling to improve performance, there is a silver lining for California: It made one of the bigger improvements in test scores over the six years. For both grades, California’s rate of improvement ranked 16th among the states.

The NAEP scale for science scores ranges from 0 to 300. California’s scores for 4th-graders rose four points: to 140 from 136 in 2009. That’s the same as the average national increase to 154 from 150. But the scores for 8th-graders rose six points, to 143 from 137, while the national average increased four points, to 154 from 150.

The NAEP science tests were conducted as California is rolling out the new Next Generation Science Standards that are aimed at improving science learning among the state’s 6.2 million public school students. A new science curriculum framework aligned to the standards, which abandons old memorization and textbook learning in favor of hands-on exploration of science, is expected to be adopted by the State Board of Education early next week.

Bill Bushaw, executive director of the National Assessment Governing Board, the elected and appointed officials who oversee the content and operation of NAEP, said California needs more time to produce better results.

“It’s important to monitor (the state ) over the next several years,” he said. “It takes time to get (the NGSS changes) into the classroom.”

California’s NAEP ranking reflects students “proficient” or “above proficient,” the highest of four levels. California had 24 percent of its students in both grades at those levels, well below the national averages of 37 percent for 4th-graders and 33 percent for 8th-graders.

Proficient means the student demonstrated competency in challenging subject matter and had analytical skills appropriate to the subject matter. Above proficient means students demonstrated superior performance.

The other categories are “below basic,” which means the student has no mastery of the science content, and “basic,” which means partial mastery.

“More of our children are on track to succeed,” said U.S. Education Secretary John King Jr. in a conference call with reporters.

The science assessments come every few years as a snapshot of how students are learning. They examine three content areas: physical science, life science, and earth and space sciences.

The new assessments were given to 115,400 4th-graders and 110,900 8th-graders around the country. Another 11,000 test-takers from 12th grade participated in the assessment, but NAEP did not provide a state-by-state breakdown.

Nationally, almost all ethnic groups made gains, and the achievement gaps between white and black students and white and Latino students narrowed in grades 4 and 8. At grade 12, student performance results have remained stable since 2009 for the nation overall and for all ethnic groups.

The results from 2015 showed that the gap in average scores between boys and girls had closed at 4th grade and narrowed at 8th grade. At grade 12, male students scored five points higher, on average, than female students. This gap has not changed significantly when compared to the gap in 2009.

“More of our children are on track to succeed,” said U.S. Education Secretary John King Jr. in a conference call with reporters.

Jessica Sawko, executive director of the California Science Teachers Association, said she didn’t think the NAEP results are a fair measure of what students in California are being taught, mainly because of the shift to the NGSS-based curriculum in the state.

However, she said, “The NAEP results do tell us what we’ve known for a long time. California students need more science, and high quality science, starting in elementary school.”


Thanks for reading.

    Very detailed article, hopefully they can change the poor marks for our California students. I like how they stated students need “more high-quality science in elementary school.” This is very true because starting at an early age these kids should be exposed to this sort of quality education. Science is a very hands-on subject and to change these grades the quality cannot be underestimated.

    “The NAEP results do tell us what we’ve known for a long time. California students need more science, and high quality science, starting in elementary school.”

    When will the California country offices of education and the districts realize that science is the perfect vehicle for teaching reading, writing, calculation, analysis, et. al. in the elementary setting.
