50 Support development of skills, knowledge, and attitudes amongst participants, e.g., via trainings or by sharing instructions, so participants can learn to use sensors and devices, judge the quality of collected data, understand its (in)validity, and share data via dedicated platforms. The setting for providing training needs to match the purpose. For example, an online training may not be the most suitable method for the use of physical devices such as a flowmeter which may need hands-on field skills developed in practice. Where possible, partner with local schools and teachers. Jointly develop educational resources around citizen science linked to educational curricula. This helps strengthen science literacy, raise environmental awareness, and transfer certain skills for the use of observation or measurement tools.
