The appropriate design for this study is a 2 x 3 x 2 factorial design. Gender is a binary variable, hence 1 x 3 is not required. There are three classifications of socio-economic status, hence the 2 x 3. And there are two teaching methods, hence the 2 in the third dimension. The additional variable is not necessary for this design.
