The mere-exposure effect is the phenomenon whereby liking increases simply from familiarity with a stimulus, also called the familiarity principle in social psychology. Robert Zajonc led research on it from the 1960s to 1990s, showing that an initial fear/avoidance response to novel stimuli decreases with repeated exposure and turns into liking. A meta-analysis of 208 experiments by Bornstein (1989) found an effect size of r=0.26, with the effect typically reaching its maximum within 10-20 presentations.

Experiential learning is defined as learning through experience, or more specifically learning through reflection on doing, distinguished from classroom-based learning by the learner's active role. David A. Kolb systematized the modern theory in the 1970s, building on the work of Dewey, Lewin, and Piaget. Learning is described as a cycle of four stages: concrete experience, reflective observation, abstract conceptualization, and active experimentation, with genuine learning requiring active engagement, reflection, analytical skills, and decision-making/problem-solving skills.

A school garden is an area designated for students to learn how to grow plants and produce at school, aimed at improving students' health, social development, and academic achievement. In Europe, the practice began in Schleswig-Holstein in 1819 and spread, reaching about 20,000 schools in Austria, 45,000 in France, 8,000 in Russia, and 2,500 in Sweden by the early 20th century. Research suggests the experiential nature of gardening increases preference for and consumption of fruits and vegetables, though more quantitative research is needed to prove benefits to children's health and wellbeing.

A study measuring soil lead by X-ray fluorescence at 31 Brooklyn public schools with active garden programmes, sampling both garden beds and adjacent school grounds. Proximity to 306 known environmental hazard sites was mapped geostatistically and combined with demographic data and soil-management surveys. Of the samples, 42% exceeded the US EPA's minimum screening level for child-accessible soils near known lead sources (100 ppm); garden soils showed lower average lead concentrations than adjacent school-ground soils. The authors argue that soil lead in schools, and the disparities in it, have received far less attention than lead in paint and water.

Set against urbanisation that has cut farmland and limited access to fresh vegetables, this study evaluates garden towers as a vertical landscape element for community-based vegetable production. Using a descriptive-evaluative approach, it assesses 105 garden-tower units distributed to 21 women farmers groups in and around Bogor, Indonesia, and discusses their contribution to food availability and social-ecological resilience in dense settings.

A community service program at PKBM Cahaya Rejeki involved 20 students in hands-on workshops to build vertical gardens using recycled materials. The program aimed to improve urban youth's understanding of vertical agriculture in non-formal settings. A Wilcoxon Matched-Pairs Signed-Rank Test showed a statistically significant increase in students' agricultural knowledge, supported by field observations of increased enthusiasm and confidence.

This systematic literature review analyzed 58 empirical studies on nature-based instruction (NBI) in science education from 2021-2025, focusing on formal and school-linked learning settings. Most studies used qualitative or mixed-methods designs, with outcomes primarily in affective and cognitive domains. Recurring challenges included limited causal designs, short follow-up periods, and inconsistent implementation reporting.

This research investigated the potential of urban agriculture to overcome food crises and impact food security. Using a mixed-methods approach (quantitative and qualitative), the study found that people practicing urban farming are supported in terms of urban farming skills, food security, creation of green open spaces, entrepreneurial opportunities, fulfillment of nutritional needs, enjoyment of fresh crops, creation of community bonds, educational benefits, and awareness for mental health and the environment.

This quantitative study examined opportunities and challenges in agricultural crop production within two urban school communities in the Philippines (Jalandoni Memorial National High School and Iloilo City National High School) during the 2024-2025 school year, involving 352 Grade 10 students. Students reported practical skills, improved food access, environmental awareness, and community engagement as opportunities in urban gardening, but cited limited space, inadequate skills, resource gaps, and weak support systems as challenges. No statistical relationship was found between opportunities and challenges.

This study designed school gardens as an educational strategy in five campuses of the La Buitrera Educational Institution in Cali, Colombia, involving 1,689 students and 73 teachers. Using a qualitative participatory action research approach, it found significant differences in garden area (e.g., San Gabriel with 2,650 m² and 161.67 m²) and student concentration (e.g., García de Toledo with 579 students). The characterization revealed infrastructure and population differences, a predominance of aromatic-medicinal species, and student-teacher complementarity, indicating a need for adapted strategies for sustainable school gardens.

This study examined the influences of family, school, and sociodigital networks on environmental awareness among secondary school students in urban and rural Cochabamba, Bolivia. Data from three schools showed students' environmental concerns varied by region, and the internet was their primary information source. Despite isolated initiatives like school gardens, schools did not effectively integrate environmental education into the curriculum, limiting its formative impact.

This study evaluated the effect of educational interventions on knowledge, consumption, acceptance, frequency of intake, planting of vegetables (focusing on endive), and help with culinary preparations among 260 schoolchildren aged 6 to 10 in public schools. The intervention based on setting up a school garden (G4) was the most effective, promoting a significant increase in knowledge about endive, acceptance, frequency of consumption, and involvement in planting a garden. Theoretical-practical activities (G2) and cooking workshops (G3) were effective in increasing children's knowledge of vegetables, but workshops also resulted in less willingness to try new vegetables.

This exploratory Q-methodology study investigated how university students in sustainability programs conceptualize sustainable food systems. Analysis revealed five distinct narratives, with consensus on food security and transparent governance. However, elements like urban agriculture, GMOs, and food traditions were consistently deprioritized by the participants. The findings emphasize incorporating plural perspectives and context-sensitive approaches in food system research and policy.
