The "Framework for K-12 Science Education" (NRC; 2012) placed renewed emphasis on creating equitable science learning opportunities for all learners by engaging in three-dimensional learning experiences: disciplinary core ideas, crosscutting concepts, and science and engineering practices. Additionally, the "Framework" calls…

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…

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…

Achievement in the learning area of science in Zimbabwe shows significant gaps in comparison to other countries in the global south. Science achievement of bilingual learners has been discussed at different levels, including cultural responsiveness in science teaching, but the emphasis has been placed primarily on the development of science…

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…

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…

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…

The few studies conducted to date on the affective dimension of CLIL (Content and Language Integrated Learning) have predominantly focused on the relationship between motivation and language attainment, which points to a need for further investigation. To this end, this cross-sectional study aims at researching the degree of correlation between…

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. Given the power that assessments have in today's education systems, our project provided a series of workshops for teachers where they explored students' emergent…

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…

The low enrolment, lack of interest, exacerbated by the general poor performance in physical science in South Africa paints a gloomy picture about the status of physical science in the country. Despite the fact that there might be other factors at play, one factor which cannot be ignored is the discourse about the use of language in the science…

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…

The purpose of this study was to compare and describe 8 fifth-grade classrooms by their teachers pedagogy during a quasiexperimental, longitudinal, and field-based project focused on increasing English language learners' (ELLs') achievement in science and language. The larger study found statistically significant and positive intervention effects…

Across Europe we can observe the reinforcement of monolingual education policies, despite increasing multilingualism. Recent research has shown that the emphasis is on language proficiency in the socially dominant language. This is viewed as the key to educational success. The use of other languages or linguistic repertoires is not valued in…

Thirty-five elementary teachers participated in a yearlong professional development (PD) program that was designed to foster a culture of on-going teacher learning to promote the co-development of science and language literacy for English language learners (ELL). An explanatory design methodology was used to determine the degree to which science…
