Linking the Local and Global:Why is it important?
An essential aspect of what geoscientists do.
An important tool for helping students learn.

What do geoscientists do? How does the Earth work? What is the impact of the Earth on
humans? What is the impact of humans on the
Earth?
In each case moving between local and global is essential

Developing Geoscience Expertise Integrating observations at global and
local scales is a fundamental aspect of being a geoscience expert.
To the extent that we want our students to understand what it means to do geoscience they must understand how we do this.

Helping Students LearnLessons from Learning Science Learning is additive, it builds on current
understanding Developing understanding is an activity The ability to use knowledge is a critical
aspect of learning
How People Learn, NRC 2000

Knowledge is additiveexisting knowledge is used to build new knowledge Builds on existing knowledge
What are initial preconceptions? What are misconceptions?
New knowledge is organized in the context of existing knowledge
Experience, attitudes and beliefs influence learning

Understanding is actively constructedstudents must be engaged to learn
Motivating students to learn (Edelson) Task Demand (a need to know) Elicit Curiosity (surprising observations)
Relevance or Empathy (Taber) Students are interested in learning about things
that impact them They can be engaged in learning about things that
impact others because they are empathetic

The local can motivate learning about the global Local issues that impact students or
their families can create task demand for learning about global processes
Local observations or tactile experiences can elicit curiosity about global processes

Going the other way Global phenomena in the news can
motivate learning about local situation and processes

If they learn it can, can they use it? Learning context influences when we
recall information Applying concepts requires practice
If we want students to be able to integrate local and global to learn about the Earth and to answer questions in their lives, we must teach in this context

Linking Global and Local Enables Learning Builds on familiar Motivate learning Essential to learning skills that enable
use in geoscience and life
