BioBlitzes, typically one-day citizen science (CS) events, provide opportunities for the public to participate in data collection for research and conservation, potentially promoting deeper engagement with science. We observed 81 youth at 15 BioBlitzes in the U.S. and U.K., identifying five steps participants use to create a biological record (Exploring, Observing, Identifying, Documenting and Recording). We found 67 youth engaged in at least one of the steps, but seldom in all, with rare participation in Recording which is crucial for contributing data to CS. These findings suggest BioBlitzes should reduce barriers to Recording for youth to increase engagement with science.
Background
Elementary educators are increasingly asked to teach engineering design, motivating study of how they learn to teach this discipline. In particular, there is a need to examine how teachers reason about pedagogical situations and dilemmas in engineering—how they draw on their disciplinary understandings, attention to students' thinking, and pedagogical practices to support students' learning.
Purpose/Hypothesis
The purpose of our qualitative study was to examine elementary teachers' pedagogical reasoning in an online graduate program. We asked: What stances do teachers take toward learning and teaching engineering design? How do these stances shift over the course of the program?
Design/Method
We identified two teachers, Alma and Margaret, who exhibited productive shifts in their pedagogical reasoning during the program. Drawing on interviews and videos of their teaching, we developed case studies characterizing their stances toward teaching and learning engineering.
Results
Alma shifted in her reasoning about teaching the design process, from treating it as linear, discrete steps to recognizing the dynamic, overlapping nature of design practices. Similarly, Margaret shifted in how she reasoned about failure and iteration, recognizing the need to help students analyze unexpected design performances to learn from and iterate on their designs. For both teachers, these shifts were dynamic and nonlinear, reflecting both context‐sensitivity and growing stability in their reasoning.
Conclusions
Engineering teacher educators should provide opportunities for teachers to reason about the specific pedagogical dilemmas in engineering and consider how teachers integrate disciplinary understandings with attention to students' reasoning and actions and pedagogical practices.
This study was conducted in a museum-based lab setting where scientists research the genetics of taste. Unlike academic labs with graduate students, the museum lab model trains volunteers (community scientists) who are (in true citizen science fashion) primarily responsible for enrolling museum guests into clinical studies; thus, they collect the bulk of the data for the research. Like most public participation in science research, the non-professional contributions have historically been largely limited to data collection; however, this study shows the power of invitations and structured opportunities for expanded participation among citizen scientists in a wider range of science practices. Through interpretive case study research, we examine how community scientists exercise agency and respond to opportunities for expanded participation in scientific practices including study design, data analysis, and dissemination of scientific findings through work on scientific articles. The case study research findings show that providing opportunities for involvement is only part of what accounts for community scientists' expanded participation. Dialogic negotiation of participation is also necessary, through bids and responses to bids, and through proffered guidance and scaffolding. Committed involvement thus entails deep cultivation and nurturing by both the museum staff, and at times, other more knowledgeable volunteers. Expanded participation is also bolstered by one's capacity, motives for, and satisfactions from pursuing those opportunities that align with past, present, or future interests and identifications. Such interests and identifications contribute to community scientists' willingness to overcome barriers and time constraints when they arise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
