There are five parts to the G.R.A.S.P. model and an example from the Defined STEM performance task "Green Construction (Grade 12)":
Goal - The Goal provides the student with the outcome of the learning experience and the contextual purpose of the experience and product creation.
Your goal is to determine a number of "green" strategies that can be used to build a new house on a piece of land in Lakewood, Wayne County, in northeastern Pennsylvania. As you investigate this building site, you will need to determine how the topography and geography of the land can be maximized to create an energy-efficient house that is economically feasible for the homeowner.
Role - The Role is meant to provide the student with the position or individual persona that they will become to accomplish the goal of the performance task. The majority of roles found within the tasks provide opportunities for students to complete real-world applications of standards-based content.
You are an energy efficiency engineer for a new "green" construction company. You are responsible for developing energy-efficient projects by identifying, assessing and structuring "green" solutions to meet the future homeowners budget, while also building an environmentally friendly structure.
Audience - The Audience is the individual(s) who are interested in the findings and products that have been created. These people will make a decision based upon the products and presentations created by the individual(s) assuming the role within the performance task.
You will need to present your findings to the homeowner, and then to the local zoning board for approval of your "green" strategies. These strategies must be environmentally friendly, cost efficient, conserve energy, and contribute minimally to the local landfill.
Situation - The Situation provides the participants with a contextual background for the task. Students will learn about the real-world application for the performance task
As you conduct the site investigation, you will need to consider three primary objectives. First, you will need to determine how much sun the site receives throughout the year. This will be important as you look to provide hot water and supplemental electricity to the homeowners. You will need to look at the direction for placement of the solar panels and the size of solar panels to be utilized. Secondly, you will need to consider the trees on the property and which trees will need to be harvested. Of the harvested trees, how can these trees be recycled and used as part of the home building process. Finally, you will need to consider rain barrels for your home based upon annual rainfall. As your investigation goes forward, you will develop and define technical and economically feasible applications.
Product - The Products within each task are designed using the multiple intelligences. The products provide various opportunities for students to demonstrate understanding. Based upon each individual learner and/or individual class, the educator can make appropriate instructional decisions for product development.
