The Effect of Using Brain Storm Strategy on Developing learning Processes by Fifth Secondary/ Scientic Branch in Biology

. (73) (35) (38) (18) (20) (0.80) (2009/2010) (T-Test) .The current research aims to know the effect of using brain storm straegy on developing learning processes by fifth secondary classes / scientific division in biology. To achieve that, a null hypothesis was put. The researcher used the experimental design of two equivalent groups. One is experimental and the other is control. The sample was (73) falling in (35) in the experimental group and (38) in the control group. Equivalence between both groups was done in (biology degree in mid year, IQ test results time age measured in months, Pre-learning processes tests and academic level of parents) variables. To realize the aim, the researcher made a test of (18) items to measure the validity of the tool, presented a panel of experts to verify the surface validity and applied on a pilot sample to reveal the mechanism of virtual appliance. stability factor was found using Kodur-Ritcharson Formula recording (0.80) labeled good. The experiment began at the second semester of the academic year 2009-2010 and after applying T-Test for two independent samples to treat the data statistically. The results showed surpass of the experimental group over the control group in developing learning processes.
