In A Class By Themselvs For Progress! Roof - Top Experiment At London School Shows Remarkable Results . Astonishing results have followed the introduction of a " roof - top " schoolroom at Popham Road Boys ' School , Islington . The schoolroom was installed last year to accommodate 30 backward and ailing boys . Records show that the pupils have gained in height , weight , and general fitness . The classroom is furnished with folding desks , blackboards , a master ' s table and a weighing machine . It has even been fitted by the boys with electric light . Mr . A . W . Dean , the headmaster , is so satisfied with the results of the experiment , that other classes are to use the roof - top room .
