Despite the rapid growth of English Medium Instruction (EMI) programmes around the globe, the language goals in such programmes have not been clearly defined, making it difficult to evaluate their success. Accordingly, our paper reports on a study that attempted to identify the language goals, operationalised as the vocabulary expected of…

As the content knowledge of English language learners and immigrant students is assessed in their less proficient language, the validity and fairness of assessments related to those students have been widely discussed. However, such assessment issues have not received much attention in rapidly expanding bilingual education programmes, where…

The Office of English Language Acquisition (OELA) has synthesized key data on English learners (ELs) into two-page sheets on a variety of subjects. This fact sheet provides the following data on ELs in the United States over the 2017-2018 school year: (1) Percentage of Students Enrolled in K-12 Who Are English Learners; (2) English Language…

Integrated assessment evaluates language proficiency through tasks that require the test-taker to produce a written or spoken output based on listening or reading comprehension (reading or listening-into-writing or speaking). Since integrated assessment aims at reflecting the communicative and cognitive requirements of academic life and other…

This article examines the conceivable rationales as to why Korean students' English-speaking proficiency scores are not as outstanding as other international standardized test scores such as the Trends in International Mathematics and Science Study (TIMSS) and the Program for International Student Assessment (PISA). Despite the efforts of the…

This article claims to provide evidence on whether content-subject and cognitive achievement vary in CLIL (Content and Language Integrated Learning) and non-CLIL classrooms in the framework of a newly introduced CLIL programme in Italy. A standardized and validated science test (TIMSS) was administered to a sample 988 fourth-grade students. The…

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…

Positioned in the Hong Kong education context, this article evaluates the effects of teaching science through home and second languages (i.e. Chinese and English) in Secondary 2 (or eighth grade) science classrooms. A total of 479 students, divided into two language instruction groups, participated in a teaching intervention comprising 16 lessons…

Vocabulary plays an important role in the Content-Based classroom, making EFL Students' science vocabulary knowledge critical to their content understanding. The purpose of this action research was to enhance students' science vocabulary knowledge of 9th grade students through science vocabulary crossword puzzle (SVCP) practices. The research…

An action research was conducted with class 12 science students (n=15) for three months with an aim of helping students improve their academic writing skill through mini revision lessons and feedback. The study was conducted based on pre-test-intervention-post-test design using mixed method. Test scores and interview were two main data collection…

We report on the use of bilingual constructed response science assessments in the context of a research and development partnership with secondary school science teachers. Our project provided a series of workshops for teachers where they explored students' emergent reform-oriented science meaning-making in our project-designed assessments. We…

This paper investigates students' performance in content-subjects in the framework of CLIL programmes in Spain. So far, CLIL research has focused primarily on language attainment in the L2 and the L1, but students' achievements as regards content-subjects have been largely ignored. Competence in Science in the L1 is analysed by comparing pupils…

This report presents Advanced Placement (AP) and International Baccalaureate (IB) examination participation and performance results in Texas public schools for the 2019-20 school year. Data are provided by student characteristics, including race/ethnicity; gender; and economic, at-risk, dyslexia, English learner, foster care, homeless, immigrant,…

The Cultural Heritage Bilingual Program (CHBP) was developed for English Language Learner (ELL) students from language groups not served by current bilingual programs in the Houston Independent School District (HISD). The two main bilingual programs in the district (Transitional Bilingual and Dual Language Bilingual) are designed to serve ELLs…

Whilst the role of disciplinary literacy in science, technology, engineering, and mathematics (STEM) education is becoming more prominent, there appears to be little adaptation or allowance made for English as a foreign or second language (EFL/ESL) students learning science in English, as well as no clear understanding of what comprises…
