Orlando, Fla. ? Florida has written new standards for teaching science that for the first time say public school students need to learn about evolution.

The proposed science standards, released Friday, call evolution one of the “big ideas” that must be taught as part of in-depth, hands-on learning.

Florida’s plan is part of a larger push to improve science education, but could set off a battle over beliefs.

Current standards do not use the word evolution – long a controversial word in education – but do require teaching evolutionary concepts in public schools.

The Thomas B. Fordham Institute in a 2005 report gave Florida an F for its current science standards, saying they were “sorely lacking in content,” “thin” and “nebulous.” In particular, the report criticized the “superficiality of the treatment of evolutionary biology.”

A group of teachers, professors and others started rewriting the science standards in May, aiming to beef up learning in a state where fewer than half of its students are proficient in the state’s science tests.

Florida students also lag behind on national tests, even as the United States lags behind other countries, particularly those in Asia.

“If we want to be competitive in the world, we have to do this,” said Susan Brennan, a Seminole High chemistry teacher in Sanford, Fla., who helped write the new standards.

The revisions aim to give more concise directions to teachers and more engaging information to students.

“Lots of time kids have a feeling that it’s just a collection of facts,” Brennan said, but science is wondering, investigating and solving problems. “Scientists are very creative people.”

The proposed standards are more specific and more limited and will help science education because they recognize “kids aren’t going to be able to absorb 50 new topics a year,” said Paul Cottle, a Florida State University physics professor who helped draft them.

The public has 60 days to comment on the changes. Then they go to the State Board of Education as early as January for approval.

State officials say the draft is a step toward improving science instruction. They fear that without changes Florida students will be ill-prepared for college and for a technology-based workplace.

“We’ve got to start developing more scientists,” said Mary Jane Tappen, executive director of Florida’s Office of Math and Science at the Florida Department of Education. “We’ve got to improve science education.”

The draft standards are based on those used in other countries with top science-education programs, such as Finland and Singapore, and the recommendations of national education and science groups. They reduce the number of topics students are taught and push for a deeper understanding of key “big ideas,” one of which is “evolution and diversity.”

Evolution education has long been controversial, most recently in Kansas, Ohio and Pennsylvania. The debate once focused on whether schools should teach the Biblical version of creation – that all living things were created fully formed by God – or that they evolved, as described by Charles Darwin.

In recent years, some have pushed for teaching “intelligent design,” which holds that aspects of living things are best explained by “an intelligent cause rather than an undirected process such as natural selection.” Others have pushed for teaching that the theory of evolution does not fully explain the origins of life.

Fred Cutting, a retired engineer who served on the standards committee, wanted the new document to reflect that latter view and to let students know that scientists do not yet have all the answers.

“If you want students to understand the theory, they have to understand the pros and cons,” he said, adding that the draft presented too “cut-and-dried” a view of evolution.
