Citizen Science, Experts, and Expertise.

Interest in citizen science is growing among both scientists and community groups who are interested in creating natural resource management projects. Such projects have the potential to result in social learning, which can further reinforce resource stewardship. Data to study this learning process, however, remain scant. Using transcripts from four different natural resource management projects, we use discourse analysis to investigate the discursive practice between project scientists and community members in the development of models that were used to test ideas and subsequently modified with citizen collected data. We found that only a portion of the discussion focused on knowledge building and that only experts provided challenges to ideas being discussed. Subsequently to these challenges, however, a greater proportion of knowledge co-creation occurred.
