Introduction ( 1 )


 Recently, the C language is widely used as educational
  programming language for beginner.

 However, some students feel difficult to understand C
  programming.

              They need a study supportive tool.


                           3                               2012/12/6
Introduction ( 2 )


 PROVIT



 PROgram VIsualization Tool
 a tool which visualizes C
language.




                              4    2012/12/6
Research questions ( 1 )


Problems of PROVIT
 Image of Pointer Variable
  similar to other variables
  in PROVIT.

 Arrow of pointer variable
  interrupts other variable.

                                   Problem case
                               5                  2012/12/6
Research questions ( 2 )


 Why this research question is important

    Pointer is difficult part in C language


    Many people feel difficult to understand Pointer

    Pointer variable in Current PROVIT is not user-friendly.

                        Need to improve Image of Pointer.
                               6                               2012/12/6
Previous literature on the topic


 Improvement of Variable Expression for PROVIT

 Design and Implementation of PROVIT Console

 Source Code Editor for PROVIT




                          7                       2012/12/6
The experiment and expected results


  We hold SCCP every Thursday.
  In this class, we are going to show demo PROVIT and
   give questionnaire.
  PROVIT was evaluated by students.

  I believe students prove that this research PROVIT is
   better than Old PROVIT for students.


                             8                             2012/12/6
