In Their Own Words: The Significance of Participant Perceptions in Assessing Entomology Citizen Science Learning Outcomes Using a Mixed Methods Approach.

A mixed methods study was used to transcend the traditional pre-, post-test approach of citizen science evaluative research by integrating adults' test scores with their perceptions. We assessed how contributory entomology citizen science affects participants' science self-efficacy, self-efficacy for environmental action, nature relatedness and attitude towards insects. Pre- and post-test score analyses from citizen scientists ( = 28) and a control group ( = 72) were coupled with interviews ( = 11) about science experiences and entomological interactions during participation.

Connections between student explanations and arguments from evidence about plant growth.

We investigate how students connect explanations and arguments from evidence about plant growth and metabolism-two key practices described by the Next Generation Science Standards. This study reports analyses of interviews with 22 middle and high school students postinstruction, focusing on how their sense-making strategies led them to interpret-or misinterpret-scientific explanations and arguments from evidence. The principles of conservation of matter and energy can provide a framework for making sense of phenomena, but our results show that some students reasoned about plant growth as an action enabled by water, air, sunlight, and soil rather than a process of matter and energy transformation.
