The writing of ESL students, while sophisticated in some respects, often contains fragments and run-ons. Because these students have no reliable, self-monitoring system for analyzing their writing and because they believe they are communicating effectively, they fail to recognize their difficulties in forming complete sentences. This paper discusses a program implemented in an advanced intermediate ESL college composition class. The program proposes that students will be able to monitor their writing for incorrectly formed sentences if given a series of exercises designed to help them analyze their work. The key concept is GLUE, a term used for all connectors, including coordinating and subordinating conjunctions and relative pronouns. Using a reference list of the GLUE words in English, students first label those they have used and, then, identify the finite clauses or subject-verb (SV) units. The number of GLUE words and SVs used are counted up as the student determines the type of sentence unit s/he has created. A complete sentence requires one more SV than GLUE. In altering their work, students learn to remove an SV, add a GLUE, or in some other way make the sentence conform to the rule for a complete sentence. (Author/JK)
