A common question for the teaching of science is how to concretize the abstract. It is easy to assume that what is concrete to the science teacher is concrete to the student. However, when students actually work with particular content , the concepts may become too overwhelming in size and scope.
In this light, concrete representations can be a benefit to students’ understanding. By using real-world environments, students can translate difficult ideas or scales into a more intuitive form.
Take the Solar System for example. In his earth and space science class shown in this video, teacher Mark Goldner and his students work together to demonstrate the scale of the solar system’s celestial bodies. They use familiar objects and the school environment to imagine the size and distance of things like Earth in relation to a beach ball model of the Sun.
Classroom objects and the classroom environment can be useful tools to visualize large scale and size. And by translating concepts between physical representations and content knowledge, students have the opportunity to visualize and imagine “nebulous” astronomical phenomena.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
