You could use one way anova if you choose to ignore the teachers under
each method. You could also include the schools where the teaching took
place. If you include either one of those two factors in the analysis
they could be considered as random factors.
As an example I developed an experiment where I measured the effects of
two cleaner products on tile grout. Having two people applying the
treatments required that the applicators be introduced as random
factors.

Ahmed,
Now that I have seen the variables, it appears that the four learning
types
are actually scores on four distinct variables, representing different
learning styles. This changes the nature of the analysis considerably.
You
should consider correlation and regression. It would be possible to
conduct
a one-way ANOVA, classifying subjects by their highest score on the four
learning variables, but this approach would lose a lot of information
(e.g.,
it does not distinguish between people who are slightly higher on one of
the
four learning styles from those who are a lot higher on one of the
styles.
Can you tell us a little more about your research questions and
hypotheses?
HTH,

Hello SPSS'ers:
I have two variables, independent (types of learning; 4 types) and one
independent
variable (understanding scores). I wanna investigate the effect of
those 4
types of learning on the understanding. Which analysis would be
appropriate
in this regard? One-way or two-way ANOVA? Please advise. Thanks alot
Ahmed
