Original title: LINGUISTIC SCAFFOLDING IN CLIL MATHEMATICS: A THEORETICAL FRAMEWORK FOR INSTRUCTIONAL DESIGN
Nguyen Viet Anh · September 2026
Learning math in a second language like English is tough. Students must grasp math logic and academic words at the same time. Teachers often struggle to tell if a student is confused by the math itself or just stuck on the language. To help solve this, researchers studied learning materials from secondary education using a framework about mental effort. They created a three-step support model to make learning easier. First, it introduces key words beforehand. Second, it simplifies complex sentence structures. Third, it adds varied visual or interactive representations alongside the text. This setup aims to lower mental strain. By doing so, it can potentially help students learn math better in bilingual classrooms.
Imagine trying to assemble a piece of furniture from instructions written in a language you barely know. You might spend more energy decoding the words than figuring out which screw goes where. Now imagine the instructions first teach you the key terms, then rewrite each step in short sentences, and finally add a picture of the assembled part. In this paper, the furniture is a math problem, the confusing instructions are the academic English, and the three-step method is designed to let students focus on the math instead of the language.
For millions of students learning math in a second language, a wrong answer might mean they missed the concept or simply tripped over a tricky sentence. Teachers currently have no clear way to tell the difference. This paper offers a structured method to strip away the language barrier so the math itself can be assessed fairly.
The paper presents a theoretical framework based on analysis of secondary education materials, but does not test the model in a classroom. It does not provide empirical evidence that the three-step scaffolding improves outcomes. The framework's applicability to other subjects or age groups is not addressed.
