Pre–post survey of 46 conference workshop participants (pre n = 42, post n = 46), analysed with Mann–Whitney U tests treating the two time points as independent groups. The article reports "increased confidence to undertake pro‐environmental change" with means rising in both personal and professional life at p < 0.05; no effect size is printed.

"pre‐ and post‐workshop survey results indicated participants reported increased confidence to undertake pro‐environmental change in their personal 4.1 ± 0.7 to 4.5 ± 0.8/5 and professional lives 3.6 ± 1.1 to 4.3 ± 0.9/5 (p < 0.05) at the conclusion of the workshop."

Discussion¶

Related Claims¶

• Dietitians' barriers and enablers to pro-environmental action fall into three themes: personal, social and professional, and contextual and environmental factors — related
• Belief that a global environmental problem needs addressing was already high before the workshop and did not significantly change — related
• Global change instruction poses a distinctive challenge: learners must view global change holistically while analysing individual issues at local and regional levels — related
• Professional learning experiences shift teachers' beliefs away from traditional views toward practice-based science and increase implementation confidence, with gains leveling off after initial workshops — related
• Retrospective pre/post confidence rose on all four course learning objectives with large rank-biserial effects (N=159) — related
• The most cited barriers to adult learning are situational, but adults also face internal barriers such as low confidence in their ability to learn — a broader claim this one bears on
