Learner Verification and Revision (LVR) has been part of Florida's instructional materials adoption process since 1974, when state statutes required textbook publishers to provide written proof that their materials were revised based on student feedback before publication. Publishers were also required to collect student data and make revisions during the entire market life of the product. In 1983, the LVR guidelines were made more specific and required that the LVR be submitted by publishers prior to submitting textbooks for adoption. The current 1985 Florida LVR guidelines required four sections: (1) product background information; (2) intended learner outcomes; (3) prepublication LVR--overview of LVR process, data collection and use, instruments used, and sample revisions; and (4) post publication LVR--plans for further data collection. Training was provided for publishers, and state instructional materials councils felt it was easier to evaluate the reports. Publishers, however, expressed concerns about the cost of field testing an entire textbook, validity and reliability of students' feedback, paperwork, and lack of evidence validating LVR. In light of these problems, it was recommended that the guidelines be reviewed, that publishers work with authors in implementing LVR, and that guidelines be applied more consistently. (GDC)
