Adaptation of brain storming technique to teach standard seven learners in English composition writing offers the learners an opportunity to work well together with behaviour, collaboration and communication well natured .The objective was to determine the influence of whole class technique on learners’ achievement in composition writing skills in public primary schools in Kisumu County. The piagets theory 1967 was used to determine brain storming, technique on standard seven learners achievement in English composition writing skills. Non-equivalent control group with pre and post –test groups research design was adopted. The sample size of 292 was drawn from 6 teachers of English, 6 head teachers and standard seven pupils in public schools. Data was collected via questionnaire, observation schedules and check lists. Analysis was done using descriptive statistics.The findings indicated that brain writing strategy is moderately used (m= 3.40 SD of 1.269), pie storm teaching technique is highly used (m= 3.733 and SD of 1.796), and brain wave and brain writing strategy relatively contribute to learners’ composition writing skills The computed z values for brainstorming technique elements revealed a z-statistic value higher than the z- Critical value and P-value less than 0.05. Thus, the study rejected the entire five Null hypotheses as there was a statistically significant relationship between: individual group technique, whole class technique, small group technique, round robin technique and relay technique; and learners’ achievement in composition writing skills in public primary schools in Kisumu County. For policy makers and implementers, ministry of Education and Kenya National Examination Council, should address the use of inquiring-based learning in order to provoke critical-thinking in learners as the new (CBC) gets rooted to curb the negative attitude of embracing change of teaching for life and not for exams .For theory similar studies should be carried out using inferential statistics, especially multiple regression analysis to assess how the individual strategies of brainstorming teaching technique contribute to overall learners’ learning achievements. Other researches can use the Humanist child development theory to cater for the concerns of a paradigm shift to the thinking about holistic development of the learners. .
