The purpose of this assessment probe is to elicit students’ initial ideas and attitudes about the procedure that should be followed when testing models to determine if a design solves the problem. The probe is designed to see if students recognize how a design can be improved based on a careful analysis of the result of the test. 

The purpose of this assessment probe is to elicit students’ ideas about how science and math are both used in engineering. The probe is designed to get students to think about the various ways science and math are applied to designing a physical structure such as a bridge.

The purpose of this assessment probe is to provide practice in using a decision matrix. The probe is designed to see if students are able to interpret a decision matrix and to help you determine difficulties they may encounter.

The purpose of this assessment probe is to elicit students’ ideas about different types of models commonly developed by engineers. The probe is designed to reveal whether students recognize that just like scientists, engineers make and use a variety of model types, including physical, conceptual, and mathematical models. 

The purpose of this assessment probe is to elicit students’ ideas about the life cycle of a product. The probe is designed to see how students apply the concept of life cycle analysis to determine the impact of a product on the environment. 

The purpose of this assessment probe is to elicit students’ ideas about trade-offs. The probe is designed to find out whether students recognize that trade-offs involve sacrificing one or more things in favor of another. 

The purpose of this assessment probe is to elicit students’ ideas about how engineers use designs from nature. The probe is designed to see if students recognize that designs from nature provide creative ideas for solving problems. 

The purpose of this assessment probe is to elicit students’ ideas about brainstorming. The probe is designed to determine the extent to which students understand the norms of good teamwork during the brainstorming process. 

The purpose of this assessment probe is to elicit students’ ideas about researching a problem. The probe is designed to determine the extent to which students are aware of the need to learn as much as possible about how others have solved a problem, and what the potential users want, before brainstorming possible solutions.

The purpose of this assessment probe is to elicit students’ ideas about criteria and constraints. The probe is designed to identify how students determine the criteria and constraints of a problem and whether one is more difficult to identify than the other.
