Purpose: In November 2022, the commercial company, OpenAI, launched ChatGPT. Since then, university students have rapidly become regular users of this artificial intelligence (AI) platform. One reason for this is the powerful capability of this generative AI tool to produce textual content, which in many cases, is almost indistinguishable from…

This qualitative study examines the semiotic meanings communicated through multiple representations in the teaching of an advanced undergraduate course in biology. Scientific discourse is intrinsically multimodal in nature; in other words, science is discussed and researched using multiple modes that convey meaning (Lemke, 1998). Therefore, to…

Bilingual scientific literacy (BSL) is one of the educational domains gaining prominence in twenty-first century societies. University bilingual science courses are legitimate and desirable scenarios for the promotion of bilingual written scientific argumentation (BWSA) as part of BSL. Recent studies indicate that the use of 'logical connectors'…

University bilingual science courses are on the rise because of the internationalisation of higher education. These courses are legitimate and desirable scenarios for the promotion of bilingual written scientific argumentation (BWSA) as part of bilingual scientific literacy. The problem is that very little evidence is available on how to foster…

The goal of the present study was to examine differences in cortical thickness, cortical surface area, and subcortical volume between bilingual children who are highly proficient in two languages (i.e., English and Spanish) and bilingual children who are mainly proficient in one of the languages (i.e., Spanish). All children (N = 49) learned…

In many higher education institutions in countries where English is the second or foreign language; English for Academic Purposes (EAP), English-medium instruction (EMI), Content and Language Integrated Learning (CLIL), and first language-English bilingual modules are attracting interest because of their potential to contribute to the…

English dominates as an international language for science and research. Consequently, this is the most widely used language in university bilingual (e.g. Spanish-English, Chinese-English, Swedish-English) science courses around the world. However, very little is known about how to foster bilingual scientific writing in these types of courses.…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

As the de facto language of science, English proficiency often serves as a gatekeeper for aspiring medical students in Puerto Rico because they encounter English-language instruction, textbooks, and high-stakes standardized tests throughout their studies. Employing ethnographic research methods, this case study documents the language practices in…

There has been a dramatic increase in the number of multilingual and multicultural students in U.S. schools. Because of high-stakes testing and English-only mandates, instructional practices and curricula in most urban school districts neglect the cultural and linguistic interests of their diverse student populations. In this interpretive study,…

Improving outcomes for English language learners (ELLs) in secondary science remains an area of high need. The purpose of this study is to investigate bilingual knowledge organization in secondary science classrooms. This study involved thirty-nine bilingual students in three biology classes at a public high school in The Bronx, New York City.…

This research study analyzes the effect the implementation of language-driven CLIL has on senior learners from Manuel J. Calle High School in Cuenca, Ecuador in relation to the development of written production in terms of Syntax, Content, Communicative Achievement, Organization, and Language compared to a non-language-driven CLIL classroom. There…

Individuals are at an increased risk to drop out of the STEM pipeline if they are female or Latino, and during certain periods including high school. Families are a potential untapped resource of support for high school students. Based on the expectancy-value model, we examined if a variety of parental behaviors predicted students' ability…

The Advanced Placement Program® (AP®) offers high school students the opportunity to take rigorous coursework in high school and receive college credit for AP Exam scores that meet or exceed the requirements of their attending institution. Students receiving AP credit are typically exempted from an introductory-level course or series of courses…

After reviewing the concepts of Content and Language Integrated Learning (CLIL) and Translanguaging, this article presents an exploratory study of translanguaging in CLIL contexts. Employing illustrative extracts from a collection of CLIL classroom recordings in Austria, Finland and Spain, we argue that both pedagogic and interpersonal motivations…
