摘要：Modeling is one of the core scientific and engineering practices described in A
Framework for K-12 Science Education. Students are expected to construct, use,
evaluate, and revise their models to make sense of phenomena or to find solutions to
problems. Technology tools can support the development of students’ modeling
practice when learning about environmental issues. This study investigates the
incorporation of an online computational modeling tool in a middle school curricular
unit focusing on ocean acidification. We present the advantages and challenges
experienced by students and teachers while engaging in the unit and using the
modeling tool. Our results indicate that integrating the modeling tool in the ocean
acidification curricular unit facilitates students’ interest and engagement in
environmental responsibility and focused students’ attention toward human
involvement and impact on the environment. Students perceived the tool and the
curricular unit to be relevant to their lives and important in promoting their content
learning and modeling practice. However, students and teachers reported several
challenges, mostly related to the complexity of using the modeling tool and working
with the resulting graphs and charts. We discuss these advantages and challenges and
suggest recommendations for supporting students’ modeling practice when learning
about environmental issues.
