Subclaims¶

q2 i? Expert scientist E1 had the highest degree centrality (9) in the scientific discussion. → Janet Mannheimer Zydney 2025 q2 i? Students who posted on the same artifact as the scientists were more likely to engage in scientific discussion (E-I index = -0.50, p < 0.05). → Janet Mannheimer Zydney 2025 (2)

Evidence¶

Janet Mannheimer Zydney 2025¶

Janet Mannheimer Zydney, Erin Rumpke, Gi Woong Choi, Lauren Angelone. (2025). Understanding interactions between scientists and elementary school students in a citizen science project. Instructional Science (2025) 53:949–971. https://doi.org/10.1007/s11251-025-09710-1

q2 · i? · qualitative · r2

Degree and betweenness centrality analysis (Table 3) of the Project Noah discussion found expert E1 most central in scientific discussion; E1 provided corrective feedback, explanations, and an identification website link.

"for the scientific discussion, the highest degree centrality of 9 was one of the two expert scientists: E1 who was identified as Project Noah Ranger by a patch that was earned."

q2 · i? · associational · r1

A homophily (E-I index) analysis coding students by whether they co-contributed with an expert scientist was significant (E-I index = -0.50, p < 0.05); the E-I index is not a standardized effect size.

"Students who posted on the same artifact with the scientists were more likely to engage in scientific discussion than students who did not, revealing that the scientists did influence the discussion."

Discussion¶

Related Claims¶

• Non-scientific discussion was much denser than scientific discussion, with all students participating non-scientifically but only 12 scientifically
• Participation in non-scientific discussion was weakly negatively related to participation in scientific discussion (r = 0.14, p < 0.05)
• Students, not expert scientists, played the moderating role by asking questions and making assertions, with one student bridging scientists and students — related
• Higher overall participation was not associated with scientific engagement, but co-contribution with expert scientists was — related
• A worked network example shows diffusion-based centralities capturing uptake and argumentation more accurately than traditional centrality measures — related
• Teacher-scientist pairs in school citizen science are both motivated largely by educating students, with scientists showing only lesser utilitarian data-collection motives — related
