Constructor Detail

IndividualKnowledgeModel

public IndividualKnowledgeModel(KnowledgeModel inKnowledgeModel)

This constructor is used to construct a copy of an existing knowledge model

Method Detail

getStudentLearningObjectives

public java.util.Vector getStudentLearningObjectives()

Returns a vector of the learning objectives (strings, not KUs) yet to be met by the student generated by comparing the student's KM against the correct KM saved in constructor

getAllLearningObjectives

public java.util.Vector getAllLearningObjectives()

Returns a vector of all the learning objectives (strings, not KUs) for this topic

getDetailedStats

public java.util.Vector getDetailedStats()

Returns the detailed performance for ALL the learning objectives for the chosen topic

getAbbreviatedStats

public int[] getAbbreviatedStats()

Returns the ABBREVIATED performance for ALL the learning objectives

getAbbreviatedLearnObjSummary

public java.lang.String getAbbreviatedLearnObjSummary()

Returns an abbreviated summary of the number of learning objectives met vs unmet

getTopicRoot

public final KnowledgeUnit getTopicRoot()

Returns the root of the knowledge tree subtended by current topic - currently used by conceptmap.OpenStudentModeler

updateLearningObjectives

public void updateLearningObjectives()

Updates the learning objectives by comparing the student's knowledge model against the correct knowledge model. Currently, checks even those objectives which may have been met in the past - advantage is that if a student gets that objective incorrect/missed it several times in a row, the objective will become "unmet" again. This will not modify incidentalLeafVector since the learning objectives in it are NOT the focus of this session.

updateCredit

public void updateCredit(java.lang.String learnObj,
                         int gradeType)

Updates the credit for the learning objectives by descending through the tree and assigning credit to the right (leaf or intermediate) nodes. The nodes are listed in dot.separated syntax. Note that if the objective is to test student competence, studentObjectives vector is used by student model, and if not, studentLeafVector is used. However, when it comes to updating the performance, it is always the LEAFVECTOR that is used. Both leaf and studentObjectives vectors have the same root. Using leaf vector means objectives not in studentObjectives can ALSO get updated.
