Students are introduced to the role of molecular shape, weak attractions and charge in biology and biochemistry, and then undertake a simulated Direct ELISA test.
This issue of @Concord features five ready-to-use “Lessons” that illustrate how interactive models and tools can fit into real classrooms today. Each of these lessons addresses important content that can be found in all the standards and frameworks, and does it by giving students tools with which to explore and interact. The lessons illustrate how sophisticated math and science content can be taught earlier and how generative the resulting understanding can be.
Highlight the rationale behind symbolic operations used to solve a linear equation with this tool that displays changes in the graphic and area models of functions as you change the value of each symbolic element.
Highlight the meaning of each component of a linear function's symbolic expression with this tool that links symbolic and graphic representations of translating (dragging) a line vertically or horizontally, rotating it around a fixed point, or reflecting it around the x- or y-axis.
A molecular approach to biology must develop in students an understanding of molecules, their interactions and the consequences of these interactions. Biological phenomenon now more than ever rely on chemical and physical principles for molecular explanations of the phenomenon. We have selected 10 physical-chemical principles that underlie many biological processes: we call them "Molecular Stepping Stones." Below are links to entry level model-based activities for the Stepping Stones.
This site offers tools for visualizing and computing the motion of atoms and molecules. See simulations of diffusion, dissolution, distillation, chemical reactions, chain reactions, equilibrium, catalysis, self-assembly, x-ray diffraction, light-matter interactions, DNA hybridization, nano machinery, Maxwell's law of speed distribution, Archimedes' principle of buoyancy, Pascal's principle, ideal gas laws, and more.
Highlight the language of domain and range, and the ideas of continuity and discontinuity, with this tool that links symbolic and graphic representations of each interval of a piecewise linear function.
Highlight how changing a data set affects the mean, median, and mode with this tool (created by The Shodor Education Foundation and modified by The Concord Consortium) that allows you to add and delete data graphically.
The Proportioner was developed to support your learning and your students’ learning of proportion. It allows you to manipulate images and compare their dimensions to the dimensions of other images.
Using the Proportioner, you can:
•Specify image dimensions graphically, numerically or using a scale factor
•Duplicate images and modify copies for comparisons
•Use one image to "paint" another
Highlight the meaning of each component of a quadratic function's symbolic expression with this tool that links symbolic and graphic representations of translating (dragging) a parabola vertically or horizontally, dilating it, or reflecting it around the x- or y-axis.
Highlight the meaning of a function, and see how it can be seen as something changing over time, with this tool that links a motion model to a graph.
Provides models, curricula, and professional development materials for learning about managing trade-offs between resource use and quality of life. Software is offered to help clarify key principles of sustainable thinking, including a spatial modeling and visualization tool for community design and an ecological footprint calculator.
Highlight how symbolic operations on a system of linear equations do (or do not) change the graphic or tabular representations of the system.
Note that the System Solver is a tool intended to illustrate the rationale behind the symbolic operations used to solve systems of linear equations, and not a way to learn what procedures to follow.
