Despite the linguistic diversity in the United States, English-only norms persist in educational settings, placing culturally and linguistically diverse students at a disadvantage. Translanguaging, as a linguistic application of culturally relevant practice, utilizes students’ first and second languages to enhance understanding and communication. Guided by core questions and thorough qualitative analysis, this case study delves into middle school emergent bilingual students’ engagement and experiences with translanguaging in the science classroom within a monolingual school setting. Findings indicate that translanguaging positively impacts students’ comprehension and engagement in science learning, facilitating access to content and strengthening home–school connections. However, students’ attitudes toward translanguaging are influenced by the lack of institutional support and societal language ideologies, leading to mixed opinions about its effectiveness and preferences. The study emphasizes the importance of listening to students’ voices and advocating professional support to establish multilingual educational environments to maximize the advantages of translanguaging practices.

Science education has shifted towards emphasizing science literacy rather than simply memorizing facts. Studies have shown that incorporating writing in science education engages students in higher-order thinking, fosters critical reasoning skills, and deepens subject matter comprehension. However, writing can be particularly challenging for CLD (culturally and linguistically diverse) students due to content-specific vocabulary and distinctive grammatical patterns. This case study explores six CLD students’ experiences with writing in a seventh-grade science classroom in the northeastern United States that used invention-based learning (IBL). By incorporating hands-on invention processes, IBL facilitates problem-solving and student-centered learning. The study shows how a writing-to-learn approach in science education can simultaneously support CLD students in developing a scientific understanding of abstract concepts and address the need for science literacy skills. The implications of this study suggest that teachers should integrate writing-to-learn strategies into their science instruction to promote deeper understanding and improve science literacy. By supporting students through productive struggles with writing and providing opportunities to practice scientific language, teachers can help students develop critical thinking skills and better comprehension of scientific concepts. In addition, by connecting hands-on experiences with writing tasks, educators can make science more accessible and engaging for students, particularly those from diverse linguistic and cultural backgrounds.
