public class IntegratedProblemSequencer
extends AbstractProblemSequencer

Combines pretest, practice and post-test into one session. Minimizes the number of problems solved by the student: If the student demonstrates proficiency on pretest, it does not provide practice or post-test. If the student does not demonstrate proficiency on pretest, but does not manage to solve any practice problems, it does not present posttest for that learning objective. No more need for a dummy learning objective to ensure practice. Reports the log both as an integrated sequence and as separate pretest, practice and post-test sequences

Method Detail

isSequenceDone

public boolean isSequenceDone()

If all the learning objective managers report that they are done, the integrated sequence is done, else it is not yet done. Assumes that isSequenceDone() is always called before getNextTemplate()

Specified by:

isSequenceDone in class AbstractProblemSequencer

getStatus

public java.lang.String getStatus()

Returns the number of problems that remain to be solved and the number of concepts that remain to be learned

Specified by:

getStatus in class AbstractProblemSequencer

getNextTemplate

public Template getNextTemplate()

Assumes that isSequenceDone() is always called before getNextTemplate()

Specified by:

getNextTemplate in class AbstractProblemSequencer

summarize

public java.util.Vector summarize()

Returns a list of the templates dealt by this problem sequencer, followed by the templates dealt by each of the LearnObjManagers

getLearningObjectives

public java.util.Vector getLearningObjectives()

processSpecifications

public static java.util.Vector processSpecifications(java.util.Vector specVector)

Processes the specVector, and returns a vector of three vectors: - problems specified for pre-test, any specific problems listed for practice, and problems specified for post-test. This will be used by AnalysisManager.

print

public void print(java.util.Vector currentLearnObjManagerVector)

main

public static void main(java.lang.String[] args)
