The Effect of Integrating the Sheltered Instruction Observation Protocol into the Genre-Based Approach on Eighth Graders’ Writing Performance

Abstrak

This study examined the effect of integrating the Sheltered Instruction Observation Protocol (SIOP) into the Genre-Based Approach (GBA) on students’ writing quality and explored their perceptions of the model. Using a quasi-experimental design with control and experimental groups, the study involved eighth-grade students of SMPN 2 Kendari. Data were collected through pre- and post-writing tests on recount texts, along with questionnaires and interviews. Statistical analysis using SPSS 20 included descriptive and inferential procedures. The findings revealed that integrating SIOP into GBA significantly improved students’ writing quality in content, organization, vocabulary, language use, and mechanics. Moreover, students expressed highly positive perceptions of the instructional model across cognitive, affective, and conative dimensions.
