Experimental Design

Hi,

I really need help. I am doing research on mathematics
education. I intend to compare the performance of 12 groups of students.
There is one control group and 11 treatment groups.
All the students will be tested and taught individually.
Should I just lump them all into one experiment or
do I break them up into several experiments? What are the disadvantages
of lumping them all into one experiment
with regard to the statistical analysis
done. I hope to run a one-way ANOVA. The groups are as follows:

Conventional Teaching (Control)
Conventional Teaching+Use of calculator
Conventional teaching+Use of Heuristics
Conventional Teaching+Use of calculators+Use of heuristics
Worked Example
Worked Example+Use of Calculators
Worked example+Use of heuristics
Worked Example+Use of calculator+use of heuristics
Pure Worked Example
Pure Worked Example+Use of Calculators
Pure Worked example+Use of heuristics
Pure Worked Example+Use of calculator+use of heuristics

Would really appreciate any help I can get.

Please help?

Ed.
