Investigation Information (ADI)
Investigation Information (ADI)



In this class, labs will be taught using an innovative process called Argument Driven Inquiry.  Argument Driven Inquiry (ADI) is an instructional model that blends the learning of science content with practice in the nature of science and academic writing. During an ADI lesson, students have the opportunity to “design their own investigations, gather and analyze data, communicate their ideas with others during structured and interactive argumentation sessions, write investigation reports to share and document their work, and engage in peer review” of other students’ work (Sampson, Grooms, & Walker, 2009).  In this way, the classroom models how science works in the real world.
The ADI Model:

Step 1)Task Identification – A problem is proposed, creating a need for students to work together in groups to design an investigation that will help them answer a guiding question.

Step 2)Data Generation and Analysis – Groups of students gather data related to the problem and analyze their data in search of an answer to the guiding question.

Step 3)Tentative Argument – Groups articulate and justify their claim in a way that can be shared with others (usually a whiteboard).

Step 4)Argumentation Session – Each group shares its argument with other groups (usually in a round-robin format), then critiques and refines its explanations.

Step 5)De-Brief – The teacher engages the class in an explicit and reflective discussion about the lab.
Step 6)Investigation Report – Each student writes his/her own report explaining the goal of their work, the methods they used, and a well-reasoned argument.

Step 7)Peer Review – Students review each others’ reports to ensure quality and generate high-quality feedback for individual authors (usually in a double-blind format).

Step 8)Revision – Students revise their reports based on the feedback given during the peer review session.

The Benefits of ADI:

-      Students experience science in a genuine and interactive way.

-      The process highlights the nature of science, which is a large piece of the sunshine state standards.

-      Students gain experience thinking critically, analyzing data, and creating methods & explanations.

-      Students gain experience crafting a sound argument and writing persuasively, which will improve their language arts skills.
