Summary of Projects
The EcoLEARN Projects are the result of a collaborative effort between Tina Grotzer’s lab at on causal learning and Chris Dede’s lab on virtual reality. Together, they have worked on four projects as described below: EcoMOD, EcoXPT, EcoMOBILE, and EcoMUVE. These projects use advanced immersive technologies to support learning about the complex causal dynamics of ecosystems. A separate website for the projects can be found here
The EcoMOD (Model/Modify, Observe, Design) project will explore the power of immersive virtual environments to support computational thinking and ecosystem science learning in elementary grades. Research shows that, with appropriate scaffolding, even young students can begin building complex causal concepts and understandings of systems dynamics. Developing more advanced scientific and computational thinking in later grades depends on creating a strong foundation in elementary school. However, important questions remain unanswered about how young learners think about models. EcoMOD engages learners in observation and exploration of a complex systems model based on a simulated forest building upon assets developed in an earlier project called EcoMUVE. EcoMOD’s learning goals, related to ecosystem science topics like food webs, will be taught using a systems perspective, and will shift the focus from comprehension of static representations to student interaction with dynamic computational models. Students will explore model elements through a programming sandbox, and will see the effects as they modify the properties and behaviors of the system through programming. EcoMOD will link multiple representations to help connect visual models to dynamic representations of ecosystem relationships. The curriculum will provide a highly supported, object-oriented programming environment customized to focus on ecosystems modeling and designed specifically for younger children.
Understanding how ecosystems work is important for citizens in making decisions and for students who aspire to become scientists. It requires understanding of complex causality, possible unintended consequences, and the strengths and limitations of various investigative approaches. Ecosystem concepts are difficult to learn and to teach due to the amount of information, many interacting components, and non-linear patterns involved. They are particularly difficult to teach in classrooms because ecosystems involve complexities such as large-scale problems, populations of organisms, and change over extended time frames. Learning when and how ecosystem scientists employ different approaches can help learners understand the content and process of science, yet it remains challenging to meaningfully teach these concepts in schools. EcoXPT builds upon earlier work with EcoMUVE, but goes beyond observational inquiry to explore the diverse investigative strategies practiced in the field of ecosystems science, through adding tools modeled on modern approaches and integrated with iterative cycles of experimentation, reflection, and revision.
EcoMOBILE (Ecosystems Mobile Outdoor Blended Immersive Learning Environment) is an extension of an earlier project called EcoMUVE and the resulting curriculum, developed at the Harvard Graduate School of Education with funding from the Institute of Education Sciences. In EcoMUVE, students explore a virtual representation of a pond ecosystem. In EcoMobile, funded by the National Science Foundation and Qualcomm's Wireless Reach initiative, students will use the EcoMUVE software and also extend their learning with mobile technologies through one or more field trips to a local pond environment. Two forms of technology for science education will enhance their experience in the real world.
Ecosystems science, an important strand of the life science content standards, requires an understanding of complex causal relationships. However, even after instruction, students often retain inaccurate interpretations about ecosystems’ structural patterns and systemic causality. With the research team of colleague Chris Dede, an expert in virtual worlds, we developed a Multi-User Virtual Environment (MUVE)-based ecosystems science curriculum called EcoMUVE to address these problems. EcoMUVE includes two ecosystems science curricular modules for teaching various aspects of ecosystems science. These MUVE modules are to complement and extend the current curriculum of the Understandings of Consequence Project’s Causal Patterns in Ecosystems curriculum.
