ADI Questions and Models

The Collins paper gives several examples of different types of models that can be useful in answering ADI questions that amy be proposed to students in science education. It is imperative that one understands the overall concept of ADI in order to choose the type of models that may be useful in answering these type of questions. This, however, does not mean that there is a right or wrong model to use, it is simply a matter of choice for the individual who would use a particular model for a particular ADI question. In terms of the paper, there were two different models that I think would be useful in answering ADI questions, such as this example: "What type of biological vehicles do diseases need in order to be transmitted across a population?" 

1. Temporal/Stage Model: This model can be useful because it would allow students to show different biological vehicles that the students may present, such as blood or spit, that have been previously seen in the past with disease research to have transmitted a disease. Students would have access to different web and textbook resources that will give historical evidence to support the different biological vehicles that each student choose. Other activities that can be useful to give the students are different history lectures, videos, and podcasts that students can gain information from that would show the high levels of diseases in the past, how poorly the diseases were understood, and how the diseases were understood years later. 

2. Critical event analysis: Like the temporal/stage model, it offers that historical aspect that students would need in order to justify their answers chosen. The same activities would be available to the students, but the difference would be that students would have to understand that these type of model would be used to show how the biological vehicles lead to the cause of the chosen disease. 

These two models work extremely well for my example ADI question, but it does not necessarily mean that it would work well for a different question. This allows for a diverse usage of different models for different ADI questions.
