Probe Questions Explained
Creating Conceptual Graphs: Overview
Now that we know something about the conventions of conceptual graphing we're ready to apply this knowledge to solicit information from subject matter experts.
Creating a conceptual graph is an iterative process. Initially the designer may begin with translation of information from unstructured interviews or documents. Usually the resulting graph shows a general overview of the domain. This initial graph can then be consulted to create probe questions. The probe questions provide the structure for the interviews of the subject matter experts. The designer may map the information gathered from the structured interviews onto the initial conceptual graph. The conceptual graph is then reviewed for level of desired detail. More probe questions are created to facilitate the gathering of missing information. More interviews are conducted. Observations can be conducted to gather information about tasks that the subject matter expert has automated and is incapable of verbalizing. The process is repeated until the expert and designer decide the graph is complete (See Gordon, p. 101 for more information).
Creating Probe Questions
Sallie Gordon (1994) has developed a generic set of questions that correspond to each type of node on a conceptual graph. Specific questions can be created by combining the generic question with the content of the specific node. The designer can then use the questions to structure the interview with the SME. During the interview the designer can then record the answers to the questions directly on the conceptual graph. The job aid below lists the generic probe questions.
