The purpose included planning guides or checklists for a teacher's lesson plans, and a tool of observation and research for assessing how the SIOP model is implemented. Supervisors and administrators use this SIOP Model as an observation tool in classrooms for assessing pre-service and in-service teachers. Hundreds of schools in the United States and overseas use the SIOP Model for facilitating superior quality instruction for English learners in the niche of content area teaching.
The main objective behind developing the SIOP Model was to impart and improve high quality instruction for ELs or English learners as well as to provide the teachers with a practical model of instruction that is well articulated and meticulously explained. Every day, teachers and administrators find it difficult to cope with a huge variety of newer approaches to teaching practices, reform efforts and instructions which at times compete with each other or negate the effects of each other. The SIOP Method hoped to create one uniformed model for teaching English learners.
Too many teaching methods led to a lack of uniformity and coherence in the schools and the various methods of instruction and teaching practices could not quite coexist smoothly, harming the quality of instruction for English learners. Administrators can now eliminate this confusion and lack of coherence by applying the SIOP framework. The SIOP Model is an effective framework that administrators can use to organize techniques and procedures, bringing about uniformity and coherence in a school's teaching program. This also ensures that administrators can effectively quantify and implement successful practices.
The basic target of the SIOP Model is to make academic content comprehensible for students by encouraging students' development of language skills and maximizing the academic accomplishments of English language learners through the eight different components in the SIOP Model. On the other hand, school district administrators take the help of the SIOP Model for evaluating and assessing teachers, providing them with necessary feedback to improve their performance.
