The role of Effective Supervision on academic performance of Senior High Schools in Ghana
In all facets of life, supervision has become a cross cutting edge tool and a pivot around which performance revolves. There are widespread and on going debates centred on the influence of effective supervision on academic performance in our academic institutions. This study examined the role of supervision on academic performance in Senior High Schools (SHS) in Ghana. The study was based on the collegial model of educational management and the supervision model, Theory Y as proposed by Douglas McGregor This study employed the descriptive research survey design. Through a questionnaire, data analysed was collected from 963 respondents who were purposively selected from randomised schools in each region comprising of headmasters, their assistants and heads of department of 155 SHSs across Ghana. The WAEC results (2006 2009 and 2011) of the sampled schools were analysed. Reliability coefficient of the questionnaire was Cronbach's alpha (a) 0.826. The Statistical Product and Service Solutions (SPSS) version 18 software was employed in the analyses of data using, mean, standard deviation, correlation and independent t test. The study revealed that there was a positive weak significant relationship between supervision roles of heads and academic performance of students. Moreso, there was a positive weak significant relationship between gender of heads and their supervision roles. The study recommended that supervision should be intensified in SHS. Heads of SHS should be re orientated in the new trends of supervision in schools.
