Abstract
This study evaluates the Sheltered Instruction Observation Protocol (SIOP) model and its application in the Saudi classroom from the English language teachers' perspective. The study used a descriptive study design, with a selected sample of 300 male and female English language teachers from elementary and middle schools. The research conducted a group-wide comparison using the Statistical Package for Social Sciences (SPSS). Findings illustrate that educational qualification, career status, job experience and training courses substantially affect application of the SIOP model in the classroom. Results also show that technical, financial capabilities and teachers' qualifications enable the SIOP implementation in the Saudi classroom. The study suggests the implementation of the SIOP model for the sake of transitioning from the traditional English language education system to more advanced methods concerned with the systematic evaluation of English language teachers and classroom environment standards. The recommendation includes training teachers on the SIOP model and emphasizes providing other countries with the guidelines related to SIOP implementation in the English classroom.
