Garden-based education is a philosophical orientation to teaching and learning that uses gardens as the milieu for student engagement through meaningful and relevant curricular and instructional integration in schools. In addition to their direct academic appeal in raising test scores and grades, particularly in science, language arts, and math, gardens on educational campuses, spanning pre-school through high school, are also utilized by educators for a variety of other outcomes. These include motivational engagement; social, moral, and emotional development; strengthening of institutional and community bonds; vocational skills development; food literacy; healthy eating habits; and holistic growth of children and youth. Moreover, garden-based education shows promise as a tangible and pragmatic solution to address problems of disaffection and disengagement among youth that has resulted in a school dropout crisis in many places. While specific to higher education, farm-based education and agriculture-based education that focus on growing food have parallel agendas. The vast array of outcomes linked with garden-based education may seem impressive. However, systematic research studies of garden-based education across sites to measure educational impact are missing, largely due to their marginalized status and the decentralized and localized nature of program implementation and professional training. While the idea of including gardens on educational campuses to grow food or to serve as a means of outdoor and nature education is not new, since the 1990s, there has been a surge of interest in using garden-based education across countries and continents. With its accessibility on school grounds, garden-based education intersects with parallel movements such as outdoor education, place-based education, experiential education, nature-based education, environmental education, and sustainability education. Manifested in a variety of grassroots practices that include slow food, community supported agriculture, edible schoolyards, global roots, indigenous cultural gardens, learning gardens, lifelab, living classrooms, multicultural school gardens, urban harvest, and more, gardens will likely continue to be of significance in education as there are growing uncertainties globally about food security and health matters related to climate change. Despite high stakes, standardized tests, and accountability measures that pose challenges to educators and proponents of school gardens in public schools, research shows their promise as laboratories for innovation and academic learning. Garden-based education would benefit if informed by longitudinal and large-scale research studies that demonstrate instructional and curricular rigor and integration and impact on learning outcomes. Drawing on critical and posthumanist theories that question the nature of schooling, and explicitly addressing issues of race, class, and perspectives of marginalized and indigenous scholars and practitioners would bring further credence. Practice-embedded research and co-production of knowledge that accepts complexity and conjunctive thinking, while also addressing culturally responsive pedagogy across socio-economic status, would enhance the viability of this growing movement.

From the 1960s to the early 21st century, different terms have arisen in diverse research traditions and educational contexts where teachers and researchers are interested in exploring and researching ways of helping learners to learn both language and content at the same time. These terms include content-based instruction (CBI), immersion, sheltered instruction, language across the curriculum (LAC), writing across the curriculum (WAC), and content and language integrated learning (CLIL). Common to all these traditions, however, is the monoglossic and monolingual assumption about academic language and literacy. The dynamic process turn in applied linguistics has changed our view of the nature of language, languaging, and language learning processes. These new theoretical insights led to a transformation of research on LAC toward research on academic languages and literacies in the disciplines. A paradigm shift from monoglossic to heteroglossic assumptions is also particularly important in English-as-an-additional-language (EAL) contexts.
