Hypothesis testing

Student goal orientation toward learning and doing science would affect use, evaluation, and learning differently depending on agent type

    Task Completion > Performance > Mastery > Knowledge Building

64 middle school students in two Berkeley schools:

      > took a pretest measuring orientation and inquiry skill
      > worked on an open-ended inquiry project on human memory
      > used either the IP or the C version of SCI-WISE
      > took a posttest and evaluated the system they used

Results

      > Task oriented students clearly preferred the IP system
         over the C system, likely because it gave them immediate
         advice to help them complete tasks

     > Knowledge-oriented students rated either system useful,
        but getting advice in the IP system better helped them learn

     > Knowledge-oriented students tended to make more use
        of the modifiable features of the C system

Main implications for IP theory vs. the C theory:

     > one or the other may be preferable depending on situation      
     > individual factors are important in determining theory use
