| ,Field,Annotation | |
| 0,Row,A row counter. | |
| 1,Sample,"The sample that includes this problem. If you select more than one sample to export, problems that occur in more than one sample will be duplicated in the export. " | |
| 2,Anon Student ID,The student that worked on the problem. | |
| 3,Problem Hierarchy,The location in the curriculum hierarchy where this problem occurs. | |
| 4,Problem Name,The name of the problem. | |
| 5,Problem View,"The number of times the student encountered the problem so far. This counter increases with each instance of the same problem. See ""Problem View"" in the ""By Student-Step"" table above." | |
| 6,Problem Start Time,"If the problem start time is not given in the original log data, then it is set to the time of the last transaction of the prior problem. If there is no prior problem for the session, the time of the earliest transaction is used. Earliest transaction time is equivalent to the minimum transaction time for the earliest step of the problem. For more detail on how problem start time is determined, see Determining Problem Start Time." | |
| 7,Problem End Time,Derived from the maximum transaction time of the latest step of the problem. | |
| 8,Latency (sec),"The amount of time the student spent on this problem. Specifically, the difference between the problem start time and the last transaction on this problem." | |
| 9,Steps Missing Start Times,"The number of steps (from the student-step table) with ""Step Start Time"" values of ""null"". " | |
| 10,Hints,Total number of hints the student requested for this problem. | |
| 11,Incorrects,Total number of incorrect attempts the student made on this problem. | |
| 12,Corrects,Total number of correct attempts the student made for this problem. | |
| 13,Avg Corrects,The total number of correct attempts / total number of steps in the problem. | |
| 14,Steps,Total number of steps the student took while working on the problem. | |
| 15,Avg Assistance Score,Calculated as (total hints requested + total incorrect attempts) / total steps. | |
| 16,Correct First Attempts,Total number of correct first attempts made by the student for this problem. | |
| 17,Condition,"The name and type of the condition the student is assigned to. In the case of a student assigned to multiple conditions (factors in a factorial design), condition names are separated by a comma and space. This differs from the transaction format, which optionally has ""Condition Name"" and ""Condition Type"" columns." | |
| 18,KCs,Total number of KCs practiced by the student for this problem. | |
| 19,Steps without KCs,Total number of steps in this problem (performed by the student) without an assigned KC. | |
| 20,KC List,Comma-delimited list of KCs practiced by the student for this problem. | |
