Sustaining K-12 Professional Development in Geology: Recurrent Participation in RockCamp

Researchers surveyed repeat attendees in a geology professional development program known as RockCamp in order to determine the reasons for their sustained involvement in this program. This article describes their findings, which suggest that the teachers' sustained involvement in the RockCamp Program is stimulated by situated learning experiences stressing a compare, contrast, connect, and construct pedagogy within a supportive learning community. Most teachers cited such reasons as efficacy, fun, right time of life, and support, as well as content, friendship, and methodology as reasons for their continued participation in the program.

Investigating Weather, Climate, and Climate Change Understanding of Appalachian Middle-Level Students

Climate change is an increasingly pervasive global topic, but how much of this discussion is accurately understood by students? Fully comprehending the small fluctuations associated with long term changes in temperature and precipitation is a daunting task for the general public, let alone for middle-level adolescents. This study examines students’ understanding of weather, climate and climate change. Forty-seven students, ages 12-14 from the Appalachian region of the US, were surveyed before, immediately after, and six months after a standards-based unit of instruction. The study utilized a questionnaire developed by Boon (2009) with additional questions related to weather and climate. Qualitative data were analyzed using a constructivist framework and student responses were examined for understanding of the main content ideas. The students’ understandings were analyzed over time for shifts and were also compared with previously published research (Bodzin et al., 2014; Boon, 2009). Students made improvements in some aspects of understanding with instruction but not all gains persisted to six months post instruction. Students’ distinctions between weather and climate were altered by instruction, persisted, and continued to improve with time. Students demonstrated a general understanding of the differences between weather and climate but struggled when asked to apply this knowledge to specific situations. Some improvements in students’ basic understanding of the greenhouse effect were evident, but some of these improvements degraded with time. While instruction was able to temporarily improve understanding of greenhouse gases, and the benefits of the greenhouse effect, overall students did not retain this understanding over the long term
