Generative AI has been promoted as the technology that could transform education by providing every student a personal tutor. We provide some of the first large-scale experimental evidence, from a two-year cluster randomized trial in 18 Tennessee middle schools in which randomly assigned students used Khan Academy with its AI tutor, Khanmigo, configured to coach rather than give answers, during existing daily remedial mathematics sessions. Assignment raises math achievement by 1.3 national percentile ranks per term, or about 0.06 to 0.08 standard deviations over a school year; the implied effect of a full year of active participation reaches 0.14 standard deviations. These gains resemble those...

This study examines how online Spanish language coaches, that is, trained native speakers who facilitate authentic conversational practice, perceive and use artificial intelligence (AI) in virtual language teaching. While previous research has predominantly focused on classroom teachers, we use a mixed‐methods design that includes a questionnaire and open‐ended responses from 96 coaches based in 15 Spanish‐speaking countries. We examine their familiarity with AI, attitudes toward its use, and views on how it may complement human interaction in language learning. Coaches see clear benefits in using AI for lesson planning, personalization, and idea generation, but they also express...

Estudio sobre el uso del pretérito indefinido y el pretérito imperfecto por aprendientes griegos de nivel intermedio, realizado con un grupo de diez alumnos en un curso intensivo del Instituto Cervantes de Atenas (julio de 2004). Tras comparar el sistema verbal del griego moderno con el del español, analiza los errores de sus producciones escritas y busca su explicación en la influencia de la lengua materna.

Los errores se concentran en los verbos ser, estar, tener y hacer y en el imperfecto con valor durativo. La autora diseña actividades centradas en esos dos puntos y comprueba sus resultados: el...

The main aim of this study was to unravel the possible relationship between individuals’ level of autonomy as EFL learners and academic success in terms of language learning at the tertiary level. Additionally, this quantitative study focused on exploring EFL learners’ level of autonomy and also the relationship between learner autonomy and some personal factors, including gender, age, English level, and the length of English education. In order to assess the participants’ levels of autonomy, a questionnaire consisting of 66 items was administered to 267 university students, who were Turkish-speakers of English as a foreign language. The findings showed that more than half of the learners (65.2%) had a high autonomy...

Informe de Cambridge University Press & Assessment sobre cómo están usando la IA generativa los docentes de inglés que la adoptaron pronto, con el fin de extraer de su experiencia pautas para quienes diseñan políticas educativas, programas de desarrollo profesional y guías de buenas prácticas. Se apoya en entrevistas en profundidad a 15 docentes de 13 países y seis continentes, de primaria, secundaria y educación de adultos, en centros públicos y privados.

Los testimonios giran en torno a cinco ideas: el docente que experimenta sin miedo y aprende junto a colegas y estudiantes;...

Documento de Cambridge University Press & Assessment sobre el uso de la IA generativa para crear los textos, tareas, ítems, audios e imágenes de los exámenes de lengua. Defiende que la IA solo puede tener un papel legítimo en esa tarea si se guía por principios éticos y de evaluación explícitos, con supervisión humana y con un control de calidad basado en datos. Parte de los riesgos propios de este uso —sobre todo la infrarrepresentación del constructo, que el contenido generado resulte fluido y coherente pero no cubra lo que el examen debe medir— y de las oportunidades que ofrece, como el borrador...

In the context of the ever-growing popularity of the use of English as a lingua franca, learning languages other than English poses specific motivational challenges, particularly in post-Brexit Great Britain. In England, the uptake of modern foreign languages (MFL) has experienced a forty year continual decline. To positively impact language learner motivation and, hopefully, increase willingness among learners to continue with language study beyond the compulsory phase, it is vital to target learners whilst they are still in the compulsory phase of MFL education. This study used a pre-post quasi experimental intervention design, whereby the pedagogical intervention...

How much have students’ ordinary learning processes shifted in response to generative AI, and how does that affect their durable learning outcomes? Self-report surveys show little change, while small-scale behavioral studies report widespread AI use without the scale or duration to measure learning consequences. We address both questions using a ten-year panel of 3.2 million ALEKS learning interactions for the time-on-task analysis, complemented by ALEKS PPL placement-assessment data for the proctoring and retention analyses, with a quasi-experimental design exploiting within-curriculum variation in AI susceptibility: text-based word problems transcribable into AI prompts serve as the treated group; graph-based problems...

People often optimize for long-term goals in collaboration: A mentor or companion doesn't just answer questions, but also scaffolds learning, tracks progress, and prioritizes the other person's growth over immediate results. In contrast, current AI systems are fundamentally short-sighted collaborators - optimized for providing instant and complete responses, without ever saying no (unless for safety reasons). What are the consequences of this dynamic? Here, through a series of randomized controlled trials on human-AI interactions (N = 1,222), we provide causal evidence for two key consequences of AI assistance: reduced persistence and impairment of unassisted performance. Across a variety of tasks, including mathematical...

We study how generative AI affects student learning in a randomized experiment. In proctored, in-person sessions, undergraduates learn about an unfamiliar topic and write an analytical essay with or without access to off-the-shelf generative AI, then complete unaided assessments immediately and one week later. We measure learning with knowledge tests (factual and conceptual understanding) and open-ended essays (higher-order skills). AI access raises immediate test scores by 0.27 standard deviations. These gains persist one week later. Essay quality, by contrast, changes little while students have AI access but improves in style and relevance one week later, when students write unaided. These delayed gains are larger among...
