Gloomy results persist in science performance



An article in today's edition of EdWeek reports on the continuing dismal performance of K-12 students in science, this time according to the NAEP results. Only 20 percent of 12th graders scored as "proficient" in science, lower than the proficient percentages for 8th graders ( 30% ) or 4th graders ( 34% ). These results confirm the mediocre science and math performance documented by the PISA results at the end of last year. Even more disturbing are the huge discrepancies in performance based on race/ethnicity and SES. Per the article in EdWeek, "At the 4th grade, for example, 47 percent of white students scored proficient or above, compared with 11 percent of African-American and 14 percent of Hispanic students. Meanwhile, only 15 percent of 4th graders eligible for a free lunch and 25 percent for a reduced-price lunch scored proficient or higher on the exam, compared with 48 percent of 8th graders ineligible for either."
Large percentages of students at all levels don't even reach basic levels in science, "The figure was highest at the 12th grade, where 40 percent were below basic, compared with 37 percent of 8th graders and 28 percent of 4th graders." And very few perform at high levels on the NAEP, "Only 1 percent of 4th and 12th graders earned an advanced score, and 2 percent at the 8th grade."

A wealth of data: Create your own tables!

"The International Data Explorer (IDE) has been updated to include data from the Trends in International Mathematics and Science Study (TIMSS) 2007. The TIMSS IDE allows users to create statistical tables and charts based on data for the United States and 57 other jurisdictions. Results include mathematics and science achievement of fourth and eighth-grade students; responses to student questionnaires about their background, attitudes, and school experiences; responses to a teacher questionnaire about instructional practices, resources, and background and training; and responses to a school questionnaire about school characteristics and resources.

The TIMSS IDE can be accessed at
http://nces.ed.gov/surveys/international/ide/

Data from earlier administrations of TIMSS in 1995, 1999, and 2003 will be added in the future, allowing users to examine trends in student performance across a large number of countries and other education jurisdictions."

U.S. Performance Across International Assessments of Student Achievement

This Special Supplement to The Condition of Education 2009, for the first time, pulls together the evidence from the most recent international assessments taken by nearly a million students from 85 countries worldwide. This includes three internationally benchmarked exams -- the Progress in International Reading Literacy Study (PIRLS), the Program for International Student Assessment (PISA), and the Trends in International Mathematics and Science Study (TIMSS)--to reveal how the United States compares with other countries across all three core subjects (math, science, reading) at the elementary, middle and high school level in terms of students' average scores and the percentage of students reaching internationally benchmarked performance levels. It also examines trends in U.S. student performance and the range of performance for the highest- and lowest-scoring students in each country.
The executive summary with major findings as well as links to the full text of the report is available here: http://nces.ed.gov/programs/coe/2009/analysis/

"Content first" teaching improves understanding of science concepts

As you may or may not know, the What Works Clearinghouse has a rigorous set of criteria for quantitative studies to meet their "evidence standards." Apparently this study did, and the results may offer a useful approach for teaching science concepts.

"...a review of the article "Teaching Science as a Language: A Content-First Approach to Science Teaching". This study examined whether teaching scientific concepts using everyday language before introducing scientific terminology improves the understanding of these concepts."

U.S. Students improve in math but not science on the TIMMS

This report from the National Center for Education Statistics within the Institute of Education Sciences summarizes the performance of U.S. fourth- and eighth-grade students on the 2007 Trends in International Mathematics and Science Study (TIMSS), comparing their scores with their peers internationally as well as documenting changes in mathematics and science achievement since 1995. The report also describes additional details about trends in the achievement of students within the United States, by sex, racial/ethnic background, and the poverty level of the schools they attend....
TIMSS has been administered four times: in 1995, 1999, 2003, and 2007. The United States participated in all four administrations. In 2007, 36 countries participated at grade four, while 48 participated at grade eight.

Mathematics

Results show that the 2007 average mathematics scores of both U.S. fourth- and eighth-grade students were higher than the TIMSS scale average. At grade four, the average U.S. mathematics score was higher than those in 23 of the 35 other countries, lower than those in 8 countries (all 8 were in Asia or Europe), and not measurably different from those in 4 countries. At grade eight, the average U.S. mathematics score was higher than those in 37 of the 47 other countries, lower than those in 5 countries (all located in Asia), and not measurably different from those in 5 countries.

Comparing average scores from the first administration of TIMSS in 1995 to the most recent results from 2007 showed that both U.S. fourth- and eighth-graders improved in mathematics.

Science

In science, the average scores of both U.S. fourth- and eighth-graders were higher than the TIMSS scale average. At grade four, the average U.S. science score was higher than those in 25 of the 35 other countries, lower than those in 4 countries (all of them in Asia), and not measurably different from those in 6 countries. At eighth grade, the average U.S. science score was higher than the average scores in 35 of the 47 other countries, lower than those in 9 countries (all located in Asia or Europe), and not measurably different from those in 3 countries.

Unlike in mathematics, the average science scores for both U.S. fourth- and eighth-grade students were not measurably different in 2007 compared to the first TIMSS results collected in 1995.
