An Examination of the Effects of Using a Sustained-Theme Content-Based Instruction Approach in a Community College ESL Program

One of the most effective approaches in facilitating second language learning is Content-Based Instruction (CBI). Little research has been done to examine the effect of using a CBI approach related to the success, retention, and persistence of students within such a program. The purpose of this study was to investigate the association between the use of a STCBI approach in ESL and academic success of a diverse population of students preparing for college-level courses in an ESL program at a Southern California Community College. The strength of that association was determined by gathering and analyzing quantitative data from 416 students who took the English as a Second Language Placement Assessment and subsequently enrolled in the program. The results for academic success and retention were positive but mixed for persistence.
