A number of commercial reading programs have satisfied the requirement under the federal reading law for embodying a strong research base, yet there appears to be limited outside evidence that any of them produces a conclusive and consistent effect on overall reading achievement.
The publishers of each of the top-selling reading programs make convincing cases for their effectiveness, offering research summaries, case studies, and commissioned empirical investigations to support their claims.
Scott Foresman Reading, published by the New York City-based Pearson 91制片厂视频, comes with a bound, 1,000-page synopsis of journal articles and scientific studies on which it is based. The effectiveness of McGraw-Hill鈥檚 Open Court is outlined in a commissioned study of California schools that used the program and saw some improvements in test results.
And the Boston-based Houghton Mifflin, which has cornered the profitable California market and proved popular in districts across the country, has a link on its Web site explaining the program鈥檚 alignment with the findings of the National Reading Panel and the work of prominent scholars who have influenced policymakers.
Despite such impressive documentation, it appears that none of the top commercial series鈥攊ncluding Open Court, Houghton Mifflin Reading, Harcourt, Scott Foresman Reading, and Macmillan/McGraw-Hill of New York City, all of which have been accepted for use under the stringent federal Reading First rules鈥攎eets what is called the gold standard for research.
They don鈥檛 have randomized studies pitting their products against other methods or materials; the studies they have commissioned have not been published in scholarly journals; and the companies have not documented improvements in student achievement across the range of schools and students. The programs have thrived, however, on their reputations among educators as having met the specified鈥攁nd perceived鈥攔esearch standards in the Reading First legislation, which is part of the No Child Left Behind Act.
Those perceptions were bolstered by federal officials after some of the materials were held up as examples at reading academies sponsored by the U.S. Department of 91制片厂视频 to give state officials an overview of the Reading First requirements.
Researchers and publishers criticized the officials鈥� action as a subtle endorsement of specific curricula, which is prohibited by the No Child Left Behind Act, as well as previous federal legislation.
鈥淎ssertions made by government officials in advising Reading First applicants, and claims made by publishers in advertising their products, that certain comprehensive programs are 鈥榬esearch based鈥� (with the implication that others and teacher-constructed programs are not) are not supported by anything in the National Reading Panel report,鈥� panel member Joanne Yatvin wrote in a Commentary piece for 91制片厂视频 Week last year.
Confusion Over Research
Other programs, meanwhile, such as Success for All, which has a number of studies supporting its effectiveness, have been shunted aside. That whole-school-reform program鈥攄eveloped at Johns Hopkins University鈥攈as seen a general decrease in the number of schools using it. Its founder, Robert Slavin, complains that the success of a product depends more on marketing than on science.
鈥淭here is bright potential in really using evidence and research to make a difference in reading instruction,鈥� said Mr. Slavin, a professor of education at Johns Hopkins. 鈥淏ut there鈥檚 a huge difference between marketing research and genuine research.鈥�
Exacerbating the issue, some experts say, is the widespread confusion over what constitutes credible research and how to interpret it for practical purposes.
鈥淣o Child Left Behind made them aware of the research, but whether they are becoming critical consumers of the research, I wouldn鈥檛 go that far,鈥� said Susan B. Neuman, a researcher at the University of Michigan in Ann Arbor who helped roll out the federal law as the U.S. Department of 91制片厂视频鈥檚 assistant secretary for elementary and secondary education early in the Bush administration.
Federal officials themselves may have added to the confusion.
G. Reid Lyon, the chief of the reading-research branch of the National Institute of Child Health and Human Development, for example, has suggested that commercial programs should have published studies demonstrating their effectiveness with the kinds of students for which districts intend to use them.
When asked about New York City鈥檚 choice of reading textbook last year, he said it lacked published experimental or quasi-experimental studies on its effectiveness in a variety of classrooms. Mr. Lyon hinted in a New York Times article that the text would not pass the rigorous review under Reading First, potentially threatening the city鈥檚 $111 million share. In the hope of appeasing federal reviewers for the grant program, city officials eventually agreed on another reading program for schools applying for Reading First money鈥攐ne that was accepted by state reviewers even though it, too, lacked that very kind of scientific proof.
But Ms. Neuman said at the time that she did not believe that Reading First required that higher standard of evidence.
Publishers鈥� Proof
Publishers are working hard to make sure their products accurately reflect research principles, and to gather convincing evidence that they work, said Marci Baughmann, the director of academic research for the Pearson 91制片厂视频 school group.
Like many other publishers, Pearson, the parent company of Scott Foresman, has hired a small army of researchers to consult throughout every stage of development and production of reading texts. The publisher has been gathering data from clients to map changes in student achievement, and has commissioned independent studies or reviews from prominent researchers.
Studies on the Scott Foresman program, for instance, have been submitted to the What Works Clearinghouse of the federal 91制片厂视频 Department鈥檚 Institute of 91制片厂视频 Studies, Ms. Baughmann said, in the hope of getting a positive peer review to back up the product鈥檚 claims.
Many publishers have also asked the Florida Center for Reading Research to evaluate the research justifications behind their products. The center, directed by Joseph Torgesen at Florida State University, one of a select group of researchers called on to help launch Reading First, has produced eight reports on core reading programs and more than three dozen evaluations of interventions for struggling readers.
Mr. Torgesen, who has won research funding from the NICHD and runs one of three technical-assistance centers for Reading First as part of a $37 million 91制片厂视频 Department grant, has conducted numerous efficacy studies on reading interventions. The center鈥檚 reports summarize the principles behind the programs, evaluate the content, and identify the elements of the programs that do and do not align with research conclusions. The reports do not make claims about programs鈥� effectiveness.
Beyond those appraisals, however, publishers are unlikely to see their studies in peer-reviewed journals鈥攖he stamp of approval to many in the field. The publishing process is often lengthy and could distract researchers from their other projects, according to Ms. Baughmann.
The new focus on research evidence 鈥減laces a certain amount of responsibility on the publishers to hire good academic researchers willing to work to the highest standards,鈥� she said. 鈥淏ut we don鈥檛 anticipate being able to get [their work] published in a journal.鈥�
