Abstract
Abstract A system for assessing the diagnostic reasoning ability of learners engaged in a field of study employs a coded situation test and utilizes a computerized process for grading examinations taken by the learners and for rating their capacity for diagnostic reasoning. The computerized diagnostic reasoning evaluation instrument embodies storage in a test file of the situation test description which describes, illustratively in narrative form, a plurality of problems associated with the situation test employing a plurality of phrases. Each phrase has associated therewith a respective phrase identification symbol which is used by the examinee to record answers to the examination. In a nursing embodiment of the invention, each learner selects from a listing of possible problems. Those problems which are considered by the learner to be significant and present in the situation test are then identified by storing their respectively associated code symbol. In practice, the answers by the examinee may be entered directly into a computer by the examinee, or may be recorded by the examinee on paper and later entered into the grading computer by someone else. Subsequently, the learner is asked to identify which of the selected problems are significant using supporting data, and create from coded objectives, criteria, interventions, and rationale listings an intervention plan which is proposed by the learner to resolve the major problems. Grading is achieved by reference to a computerized answer key generated by an expert, such as a teacher, and stored in a computer memory as an answer key.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
424 words
A method of operating a computing machine to assess the reasoning ability of an examinee to be evaluated, the method comprising the steps of: first storing in a test memory area situation data corresponding to respective situation phrases in a test situation description which describes a predetermined test situation, said test situation description being substantially narrative and formed of a plurality of said situation phrases, each situation phrase having associated therewith a respective phrase identification symbol; second storing in a problem identification memory area problem data corresponding to a plurality of predetermined problems each having a respective degree of pertinence to said test situation; third storing in a problem selection memory area a problem selection response by the examinee, said problem selection response specifying a selection by the examinee of at least one of said predetermined problems as being considered by the examinee to have a significant degree of pertinence to said test situation; fourth storing in a problem selection support memory area data corresponding to a problem selection support response by the examinee, and specifying a selection by the examinee of ones of said situation phrases which support said problem selection response; fifth storing in an objectives identification memory area objectives data corresponding to a plurality of predetermined objectives; sixth storing in an objectives selection memory area data corresponding to an objective selection response specifying one of said predetermined objectives as being considered by the examinee to be a correction to the predetermined problem selected in said step of third storing; seventh storing in a criteria identification memory area data corresponding to a plurality of predetermined criteria; eighth storing in a criteria selection memory area data corresponding to a criteria selection response specifying at least one of said predetermined criteria as being considered by the examinee as supporting said predetermined objective selected in said step of sixth storing; ninth storing in an intervention identification memory area data corresponding to a plurality of predetermined interventions; tenth storing in an intervention selection memory area data corresponding to at least one of said predetermined interventions selected by the examinee to resolve a problem identified in said step of third storing; eleventh storing in a rationale identification memory area data corresponding to a plurality of predetermined rationales; and twelfth storing in a rationale selection memory area data corresponding to at least one of said predetermined rationales considered by the examinee as supporting said predetermined intervention selected in said step of tenth storing, including at least a selected one of said phrase symbols for supporting said predetermined intervention.
Claim 2
Independent Claim
424 words
A method of operating a computing machine to assess the reasoning ability of an examinee to be evaluated, the method comprising the steps of: first storing in a test memory area situation data corresponding to respective situation phrases in a test situation description which describes a predetermined test situation, said test situation description being substantially narrative and formed of a plurality of said situation phrases, each situation phrase having associated therewith a respective phrase identification symbol; second storing in a problem identification memory area problem data corresponding to a plurality of predetermined problems each having a respective degree of pertinence to said test situation; third storing in a problem selection memory area a problem selection response by the examinee, said problem selection response specifying a selection by the examinee of at least one of said predetermined problems as being considered by the examinee to have a significant degree of pertinence to said test situation; fourth storing in a problem selection support memory area data corresponding to a problem selection support response by the examinee, and specifying a selection by the examinee of ones of said situation phrases which support said problem selection response; fifth storing in an objectives identification memory area objectives data corresponding to a plurality of predetermined objectives; sixth storing in an objectives selection memory area data corresponding to an objective selection response specifying one of said predetermined objectives as being considered by the examinee to be a correction to the predetermined problem selected in said step of third storing; seventh storing in a criteria identification memory area data corresponding to a plurality of predetermined criteria; eighth storing in a criteria selection memory area data corresponding to a criteria selection response specifying at least one of said predetermined criteria as being considered by the examinee as supporting said predetermined objective selected in said step of sixth storing; ninth storing in an intervention identification memory area data corresponding to a plurality of predetermined interventions; tenth storing in an intervention selection memory area data corresponding to at least one of said predetermined interventions selected by the examinee to resolve a problem identified in said step of third storing; eleventh storing in a rationale identification memory area data corresponding to a plurality of predetermined rationales; and twelfth storing in a rationale selection memory area data corresponding to at least one of said predetermined rationales considered by the examinee as supporting said predetermined intervention selected in said step of tenth storing, including at least a selected one of said phrase symbols for supporting said predetermined intervention.
