In our modern academic and professional working environments, academics and professionals, in their own specialized fields of expertise, endeavour to leave a legacy along their practising trail before they leave active practice. The legacy they leave takes several forms and some of them are research, writing and publication. The collections of manuscripts in this book is done to keep the record of these professional and academics and also to make a contribution to enable future academics and professional to be able to follow the trail of academics and professional in the teaching and learning environments to enable them know and admire the contribution of their forbearers. This prompted the editors to collect the manuscripts for editing and publication. This is our legacy for our future academics and professional in the teaching and learning environments.
