RASHI Tutorial for Human Biology Cases.

Large poster description of RASHI (2003).

Description:

Rashi is a domain independent architecture for inquiry learning environments. It contains tools that allow learners to gather data, pose multiple hypotheses, and create arguments that support hypotheses by linking to supporting or refuting data. We have used Rashi to build inquiry learning environments in human biology, geology, forest ecology, and art history, all for undergraduate level students.

Using Rashi for Differential Diagnosis

Summary Instructions:

Read the Case Statement
Use the Scratch Pad to take informal notes to keep track of "What I need to know" to help you plan what lab tests, examinations, and interview questions you need, sources you need to look at etc.
Use the Interview tool, the Lab Tests tool, and the Examination tool to gather information. Save information in the Notebook.
Whenever you have a diagnostic hypothesis, add it in the Argument Editor.
Connect your data to your hypotheses in the Argument Editor. Set the rating for each hypothesis as needed. Set the argument type (supports, refutes, etc.) for each argument item.
When you are confident that you have narrowed things down to one diagnosis, write up an explanation of your conclusion in the Report tool. Include your reasons for supporting the top hypothesis as well as your reasons for ruling out (eliminating) the others.

Overview of using Rashi for Differential Diagnosis:

The differential diagnosis process involves maintaining a list of hypotheses of what the diagnosis is, and continuously gathering evidence that will support or refute each hypothesis, in an effort to rule out all but one hypothesis.

Use medical reference sources in the book shelf or on the web to help diagnose the patient and decide what tests or examinations you will need. See the Rashi Sources tool to keep track of your sources.

Use the Interview tool to ask the patient questions; the Examination tool for physical examination; and the Lab Test tool to order lab tests (you will have to type in your "justification" before ordering a lab test, as they can be expensive.) Save all of your data to the Notebook.

Use the inquiry Notebook to save and organize your data. You can also enter your own data or inferences if you know something in addition to what is available from the Interview, Exam, or Lab tools. Use the Argument Editor to enter your diagnosis hypotheses, and to show what data supports and refutes each of them.
