Explanation of natural phenomena at one level of biological organisation almost always involves causes that are found at other levels. Although scientists thinking across levels find it easy to explain physiological phenomena, students often perceive this as a challenge. We developed a new graphic organiser called Zoom Map, which is a mode for…

The properties and functions of complex systems apply across a variety of domains of science and are at the heart of the solutions to many global crises facing the world today. As such, understanding of complex systems has been increasingly recognized as a core goal of science education. Learning about complexity-related concepts and phenomena is…

Powerful arguments have been made recently to advocate for the introduction of systems thinking in chemistry education to equip graduates to address sustainability challenges. This contribution describes systems thinking activities and an assessment tool that enables meaningful learning in first-year organic chemistry as students engage with the…

Developing students' ability to think about systems, as opposed to isolated facts, is of central importance in much of science teaching. Prior work in this area has focused on students' recognition of the processes occurring within a system. Comparatively, little work has been done on how students organise the objects that are contained within the…

One challenge associated with introducing systems thinking in chemistry classrooms is the increase in content complexity that students face when they engage in this type of approach. Placing core chemical ideas within larger systems has promise, as long as students are not overwhelmed by the added complexity. Although there are many potential…

The theory of evolution can be a useful basis for developing students' understanding of ecology. Our study used concept maps to examine the development of sixth-grade students' understanding of the Antarctic ecosystem following several evolution 'Science Days' conducted at 'Nature Campus' -- an informal learning environment comprised of a natural…

As an instructional tool, models can transform the student experience from the static to the dynamic, the flat to the 3D, and the siloed to the integrated. Few practical resources exist to help instructors transition toward model-based classroom practices. The "Modeling in the Classroom" evidence-based teaching guide provides instructors…

Based on the recommendation of the AAAS and the NRC, middle level science is the rightful introduction for a systems approach, including the study of its parts, subsystems, interconnections, and interrelationships. Dr. Seuss's "The Lorax" provides an excellent opportunity to combine ecological consequences within a systems approach (Sweeney 2001).…

For the twenty-eighth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the National AECT Convention in Orlando, Florida. The Proceedings of AECT's Convention are published in two…
