This study provides a systematic literature review of research in the field of teaching and learning mathematics through Content and Language Integrated Learning (CLIL), Content-Based Instruction (CBI), and English Medium Instruction (EMI). The review aims to examine the most relevant literature with a focus on mathematics and CLIL, CBI, or EMI in Scopus and Web of Science per the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. Based on 151 sources, 52 papers were selected according to predefined selection criteria. The papers were analysed and coded according to the following categories: (1) geographical productivity, (2) diachronic productivity growth, (3) main objectives, (4) methodology, and research design, (5) variables and measurement instruments, (6) context and sample details, and (7) main findings. The results reveal that most of the research analysed has been carried out in the Asian continent, followed by Europe. The analysis of diachronic productivity shows that the study of the application of CLIL, CBI, and EMI programs in the teaching-learning process of mathematics has notably increased in recent years, especially in the last triennium (2020–2022). Regarding the objectives of the selected corpus, the majority aimed at teaching practices and learning processes, and outcomes in mathematics and language proficiency in CLIL, CBI, and/or EMI classrooms. The corpus analysed fits within one or more of the following categories: empirical, qualitative, descriptive, correlational, and cross-sectional. The samples utilized in different studies differ significantly, both in terms of quantity –ranging from one person to 700– and in the educational level being studied, which would be primary, secondary, or tertiary education. The main variables studied in the corpus focus on mathematical competence, language proficiency, teaching practices, teacher training, science competence, and teachers’ perceptions. The most widely used instruments have been objective tests, such as questionnaires, together with standardized tests to measure some aspects related to mathematical competence and language proficiency. They are followed by an analysis of documents (academic records, teaching materials, official documents...), participant or non-participant observation, interviews, and video and audio recordings. In summary, in the scientific literature analysed, a positive or neutral view predominates on the effects of the CLIL, CBI, and EMI approaches on the learning of mathematics and the L2. This can be due to methodological issues fundamentally related to the methodology, research design, sample, and measurement instruments. Thus, we must highlight that some of the results from the selected papers must be interpreted with caution. Taking this factor into consideration, further comparative studies on a wider scale are required to examine thoroughly the effects of CLIL, CBI, and EMI on the teaching and learning of mathematics in an L2. Besides, it is important to study in greater depth the different levels of language acquisition since the research analysed shows that these have not been sufficiently addressed in the mathematical field of knowledge.

Oftentimes, teachers who identify themselves as LGTBIQ+ may feel unsafe at work, which may upset their wellbeing and destabilize their key psychological traits. Hence, feelings such as insecurity, lack of self-confidence, anxiety, and fear are on loop in their everyday lives. Thus, in this study we pursued an examination of the interplay between sexual orientation and teacher wellbeing in a cohort of seven university foreign language teacher trainers in a Spanish context. To gain insight into this issue, a qualitative study in line with the ecological paradigm was designed for the elaboration of semi-structured in-depth interviews and for the analysis of results. The main findings display teacher wellbeing as a complex interwoven system in which sexual orientation had played a core role in their identities, competences, private and professional relationships, and in the cultural and political spheres. We conclude by stating that although homophobic discrimination was a hard trial to overcome, the psychosocial capital of the participants allowed them to transform this negativity into positive assets such as queer activism in their private and political lives and in their profession as foreign language teacher trainers.

In this qualitative study, we aim to gain insight into the stakeholders’ perspectives around the inclusion of a mild intellectual disability (MID) student of perinatal origin in the foreign language (FL) classroom, and their perspectives on the student’s working conditions, and the support needed to effectively develop this student’s basic FL skills. The research hypothesis holds that the stakeholders face numerous technical, contextual, and formative challenges which hinder the MID student’s learning conditions in the FL classroom. The study was carried out in a state secondary school of the metropolitan area of Granada (Spain). Different stakeholders participated in this study. As an instrument of research, we designed an in-depth interview with open questions. The data were perused, sifted, and interpreted by means of a content analysis methodology. The main results confirm the research hypothesis since stakeholders’ perspectives are positive towards the theoretical bases of inclusive education. Conversely, we observe that these perspectives are negative when it comes to the real and effective practice of inclusive education in the FL classroom, which would allow them to tailor their teaching methodology to the real needs of the MID student and the rest of students with special educational needs (SEN).

This study examines the factors that promote well-being among content and language integrated learning (CLIL) secondary teachers in Andalusia, Spain. Using a qualitative approach, in-depth interviews were conducted with ten educators to explore the personal, professional, and social determinants of teacher well-being. The findings highlight that self-acceptance, resilience, institutional support, and financial stability are key contributors to overall well-being. Social relationships, both within and outside the school environment, emerged as crucial elements in shaping teachers' perceptions of well-being. The study further identifies stress-management strategies, including physical exercise, humor, and psychological support, as essential in mitigating professional burnout. Additionally, while teaching through a foreign language poses cognitive and emotional challenges, participants reported that it positively influenced their professional identity and personal growth. The role of foreign language teaching is particularly significant, serving not only as a pedagogical tool but also as a means of fostering identity, resilience, and professional satisfaction. However, structural challenges such as excessive workload, bureaucratic constraints, and lack of institutional autonomy remain obstacles to sustained well-being. The research underscores the importance of recognizing and addressing teacher well-being within educational policies and teacher training programs.

This study identifies two stage-specific configurations of CLIL teacher well-being in Andalusia: an ecology of proximity in Primary Education and a disciplinary-departmental ecology in Secondary Education. Drawing on 14 semi-structured interviews with seven Primary and seven Secondary teachers, the study used a deductive–inductive ecological analysis combining within-case, cross-case, cross-stage, and subsystem-coupling procedures in QDA Miner. Participants described professional well-being not merely as a subjective psychological state but in terms of professional viability: the perceived ecological enactability of pedagogically legitimate and sustainable practice. Primary teachers’ accounts foregrounded sustained pupil contact, tutorial responsibility, family expectations, classroom routines, and adaptation for younger learners. Secondary teachers’ accounts foregrounded subject specialisation, departmental organisation, heterogeneous language proficiency, assessment ambiguity, and the Primary–Secondary transition. Across both stages, participants described compensatory overfunctioning—additional care, coordination, material redesign, translation, and assessment work undertaken to keep CLIL operational when implementation conditions were perceived as insufficient. Protected coordination time, stage-specific training, shared assessment frameworks, appropriate materials, and transition structures emerged as potential regulatory leverage points. The study advances a phase-sensitive systems interpretation of teacher well-being by identifying a fast balancing loop of frontline adaptation and a slower reinforcing stabilisation trap through which restored continuity may conceal persistent underprovision.

Primary CLIL teacher wellbeing remains underexplored in France and Spain. This exploratory, context-specific qualitative study examined the factors that ten primary teachers, five in France (Montpellier and Lille) and five in Andalusia, associated with their wellbeing. Bronfenbrenner’s ecological framework, enriched with the ontosystem and the flourishing/floundering distinction, was used as an interpretive device. The interviews were analysed through reflexive thematic analysis. Participants’ accounts converged around perceived gaps in CLIL-specific training, time, coordination, and human and material resources, while differing in how they interpreted programme stability and recent policy change. The analysis tentatively developed a compensatory pedagogy of affection and a broader pattern of professional delegitimation and identity-related loss. Explicit bilingual professional shame appeared in one account. It also identified native-speaker-oriented linguistic self-demand and an emerging pattern of AI-assisted material adaptation across six accounts. We offer a provisional, context-specific tensional ecological framework to organise the relationships participants described between conditions perceived as structural pressures and personal, relational, formative, and material resources. The framework is intended as a heuristic and hypothesis-generating contribution rather than a validated causal or longitudinal model. The findings identify areas for institutional review and further research.
