This study charts the terrain of research on writing during the 6-year period from 1999 to 2004, asking "What are current trends and foci in research on writing?" In examining a cross-section of writing research, the authors focus on four issues: (a) What are the general problems being investigated by contemporary writing researchers? Which of the various problems dominate recent writing research, and which are not as prominent? (b) What population age groups are prominent in recent writing research? (c) What is the relationship between population age groups and problems under investigation? and (d) What methodologies are being used in research on writing? Based on a body of refereed journal articles (n = 1,502) reporting studies about writing and composition instruction that were located using three databases, the authors characterize various lines of inquiry currently undertaken. Social context and writing practices, bi-or multi-lingualism and writing, and writing instruction are the most actively studied problems during this period, whereas writing and technologies, writing assessment and evaluation, and relationships among literacy modalities are the least studied problems. Undergraduate, adult, and other postsecondary populations are the most prominently studied population age group, whereas preschool-aged children and middle and high school students are least studied. Research on instruction within the preschool through 12th grade (P-12) age group is prominent, whereas research on genre, assessment, and bi- or multilingualism is scarce within this population. The majority of articles employ interpretive methods. This indicator of current writing research should be useful to researchers, policymakers, and funding agencies, as well as to writing teachers and teacher educators. (Contains 6 tables and 3 notes.)
