On of my pet peeves is – literally – the misuse of the word “literally.” People often say things like, “My head literally exploded when I heard the news.” No, it didn’t. Or “The cat literally scared me to death when it jumped on the couch.” The speaker was alive to tell the story.
The title of this post is literally what I will write about: International settings and research on SIOP. It’s interesting to discover the many places in the world where SIOP has been adopted as a teaching approach.
English is currently the most popular language for people around the world to learn which isn’t surprising given how rapidly our world is becoming interconnected. Globalization and economic growth have transformed the way we work and interact, creating a growing demand for advanced language and literacy skills.
But what exactly does that mean for learners?
Today’s learners need much more than just basic English proficiency. They require the ability to communicate effectively in various contexts and with diverse audiences. This goes beyond simply speaking and writing. Students must be able to interpret and make meaningful use of written texts for different purposes, whether it’s following instructions, analyzing reports, engaging with colleagues via email, text, and social media, or reading complex literature.
Further, collaboration and creativity have become essential skills in our interconnected world. Students need to learn how to work productively with others, sharing ideas and creating innovative solutions to real-world problems. This means developing critical thinking and problem-solving abilities, as well as cultural awareness and competence to effectively navigate different social and professional contexts.
Here’s where the SIOP Model serves as a resource. SIOP isn’t just a buzzword—it’s a research-validated approach proven to effectively build both academic English and content-area knowledge. SIOP integrates language development with subject matter teaching, making content comprehensible and accessible for multilingual learners. Teachers who use SIOP carefully plan and deliver lessons that not only convey content clearly but also actively support students in developing the language and literacy skills necessary to thrive in our globalized world.
In international settings, content is taught to non-native speakers of English so that they develop proficiency in English, or English as an additional language. There are many similarities between U.S. and international contexts. In both, students are learning content material through English, but English is not their first language and is likely not spoken in their homes. The differences in the two settings include that fact that in the U.S., English is the medium of instruction for most multilingual learners while students outside the U.S. are educated in their first (or home) language and are learning English as an additional language. Instead of, for example, studying English as a separate subject area, increasingly English is used as the medium of instruction to teach content. This approach has dual benefits: learning subject matter such as science, literature or history while also developing students’ English proficiency.
At the 2025 International TESOL conference, Dr. Deborah Short and I presented the topic, Applications of International Research on Integrated Language and Content Instruction. We focused on three areas of international SIOP research: Teacher attitude, teacher
self-efficacy and fidelity of implementation, and student achievement and language development. Here is a summary of selected studies.
International SIOP Research on Teacher Attitude
The following studies were conducted in Saudi Arabia, Spain, Morrocco and Turkey, respectively. We’ll highlight below the study from Turkey.

This qualitative study by was conducted by Inceli in Turkey to explore English teachers’ perceptions of the SIOP Model and its impact on university students with limited English proficiency.
Methodology:
- Participants: 10 experienced teachers (3 male, 7 female) in an English Preparation Program for university LEP students who had not started their majors yet.
- Data Collection: Semi-structured interviews to gather in-depth insights into the teachers’ experiences and perceptions regarding the SIOP Model.
- Data Analysis: Thematic analysis to identify recurring themes and patterns in the teachers’ responses.
This approach allowed for a comprehensive understanding of how the SIOP Model influences teaching practices and addresses challenges associated with limited English proficiency. Key findings of the study included:
- Teacher Perceptions: Teachers viewed the SIOP Model positively, recognizing its structured approach as beneficial for enhancing students’ language performance.
- Identified Themes: Three main themes emerged from the interviews:
- Interest: Engaging students’ interest was considered critical for effective language learning. Content topics sparked interest.
- Understandable Content: Providing content that is comprehensible to students was highlighted as essential. Chunking and level appropriate texts help.
- Supporting Language Production: Encouraging and facilitating students’ active use of the language was considered vital.
- Implementation Challenges: Teachers noted challenges in implementing the SIOP Model, such as time constraints and the need for adequate training.
The implementation challenges cited by participants in this study are consistent with other studies in the U.S. and internationally. Teachers require sufficient time to learn and implement the features of SIOP for its application to become second nature. Coaching and peer support have also been mentioned as important supports for effective implementation.
International SIOP Research on Teacher Self-Efficacy and Fidelity of Implementation
The following studies were conducted in South Korea, Egypt, Indonesia, and South Korea, respectively.

- Song, K. (2016). Applying an SIOP-based instructional framework for professional development in Korea. TESL-EJ, 20 (1).
The study by Koura & Zahan was quasi-experimental study conducted in an Egyptian teacher training university to examine self-efficacy and teaching performance of EFL teacher candidates.
Methodology:
- Participants: 22 EFL student teachers, divided into two groups: an experimental group that received training using the SIOP Model and a control group that followed the regular teaching curriculum.
- Duration: 12-week training program.
- Data Collection: Pre/post-observations in classrooms using teaching performance observation checklist (SIOP protocol) and pre/post ratings on self-efficacy scales.
- Data Analysis: Statistical tests on observation group mean scores and self-efficacy ratings, comparing the two groups.
Key findings included:
- Enhanced Teaching Skills: The experimental group demonstrated significant improvement in teaching performance compared to the control group.
- Increased Self-Efficacy: Participants trained with the SIOP Model reported higher levels of teaching self-efficacy, indicating greater confidence in their instructional abilities.
- Motivation and Creativity: The SIOP Model was found to be motivating for student teachers, providing opportunities for decision-making and creativity in lesson planning and delivery.
Findings from the study suggest that incorporating the SIOP Model into teacher education programs can effectively develop teaching skills and boost self-efficacy among EFL student teachers.
International SIOP Research on Student Achievement and Language Development
The following studies were conducted in Pakistan, Saudi Arabia, Iran, Egypt, Northern Macedonia, and Indonesia, respectively.

Ali, Afzal & Basri conducted a quasi-experimental, pre/post design study to measure the impact of SIOP instruction on the English achievement of 8th grade students in Pakistan.
Methodology:
- Participants: 8th grade students in two government schools (experimental n=32, control, n=40)
- Intervention: 40 SIOP lessons developed and delivered based on national English curriculum for experimental group; traditional lessons for control group
- Data Collection: Pre/post Grade 8 English Achievement Test
- Data Analysis: Inferential statistical to compare pre-test scores and post-test scores between groups, and pre-post growth within experimental group
The key findings of this study included:
- There were no significant difference between groups on pre-test scores
- Statistically significant difference were found between groups on post-test scores
- Statistically significant difference we found within the experimental group comparing pre-test to post-test scores
- Teaching English through the SIOP Model significantly improved the academic level of 8th grade students.
This study recommends that teacher education programs and teacher training institutes include SIOP in their curriculum to enhance teacher knowledge and competency which may lead to improved outcomes for students.
Summary
Integrated language and content instruction is growing in implementation globally to prepare students to be successful in our interconnected world. According to studies conducted internationally (and in the U.S.), SIOP has been shown to help students access subject-area content while simultaneously developing academic English. SIOP research is taking place around the world with studies designed for the local context.
The studies presented here show that teachers’ self-efficacy in working with multilingual learners increases when they learn and practice using the SIOP Model. Teachers can become high implementers of SIOP with 1) sustained PD and coaching/peer support; 2) more awareness of language demands in content areas; and 3) sufficient time to practice using the model. When teachers implement SIOP with fidelity, student academic achievement and language development improves significantly.
