A reflection on a citizen science project in which five early-career and PhD female researchers guided school-age children across five schools to build artificial flowers, install them on school ovals, and record over repeated 10-minute observations how flower colour (yellow vs. blue) and configuration (isolated, clumped adjacent, clumped mixed-colour, clumped single-colour) affected the number and taxa of visiting insects. The project achieved a low-cost, engaging format and exposure to female STEM role models, but the authors report constraints including having to run it in a season made suboptimal by fixed school curricula, confounding of results caused by the children's own observations, and an inability to verify the collected data.

A study of Virtual School Garden Exchanges (VSGEs)—which link local gardening with global thinking by having elementary and secondary school students in different parts of the world exchange information about their school gardens and related topics via digital media—focused on educators' perspectives and the learning outcomes they observed, given ongoing controversy over whether VSGEs are suitable for Education for Sustainable Development (ESD) and whether they produce the learning outcomes educators expect. The researchers conducted 20 semi-structured interviews with VSGE educators, analyzed abductively and qualitatively. Results showed substantial overlap between observed and expected learning outcomes and ESD aims, but the data also revealed that learners engaging with international peers were affected by stereotypes and norms in varying ways: on one hand, VSGEs can lead to "Othering," which is not congruent with either ESD or the expected learning outcomes; on the other, they can inspire Transformative Learning that contributes to ESD aims. The study concludes that VSGEs hold potential for ESD depending on a complex interplay of factors, but are not guaranteed to constitute good ESD practice.

A systematic review of quantitative peer-reviewed Farm to School (FTS) research found ambiguity and variability in FTS inputs. This makes it difficult to generalize outcomes for policymakers. The study proposes a pre-tested intensity measurement tool to standardize research in this area.

A systematic review of 40 articles on school gardening programs found that quantitative research was generally of poor quality, with limited evidence for changes in fruit and vegetable intake based on self-report. Qualitative research, though of better quality, attributed a range of health and well-being impacts to school gardens, but more robust quantitative research is needed to support these findings.

A review of thirteen school garden programs for children (kindergarten to 8th grade) found methodological limitations: three studies lacked control groups, and none were randomized. While six of eleven programs showed increased vegetable intake and seven of eight showed increased preference for vegetables, four programs had no effect on intake. More research is needed to understand long-term dietary improvements.

This study investigated factors influencing career choices among graduates of an urban agricultural education program. While former students identified parents and friends as influential, and cited various reasons for their career paths, a discriminant analysis model could not distinguish between those who chose agricultural careers and those who did not after completing the secondary agricultural program.
