xiv SUGGESTIONS TO TEACHERS 



all the pupils, but to get before the individual pupils the 

 results of the class thought as corrected and related under 

 guidance of the teacher. A second period spent in the 

 laboratory or elsewhere can then be given over to writing 

 the results of these requirements, with such use of refer- 

 ence books as shall make this second period a study period 

 even as was the first. These " laboratory papers," when 

 returned to the pupils, should be preserved by them as 

 their notebooks. 



3. Assistance given pupils during these, preparation 

 (laboratory) hours may be of such nature that a consistent 

 training in the neglected art of study is secured. To 

 learn whence to get desired information, whether from 

 books or from experimental data, and how best to proceed 

 in acquiring it, ought to be one of the large factors in an 

 education. 



4. Some of the papers handed in at the close of every 

 laboratory period must be carefully reviewed and cor- 

 rected. All should 1 be returned to the pupils before the 

 next class period, some of them being marked " Not re- 

 viewed " when necessary. There is no more important 

 means of securing information concerning the ability of 

 individual pupils, and no better guide to teaching pro- 

 cedure, than is found in the review of some laboratory 

 papers out of every set handed in. Often it is well to 

 look over the papers of the same pupil every time for a 

 while. 



II. CLASS WORK 







All corrections and explanations of a general nature 

 found necessary in a review of the laboratory papers 

 should be made by the teacher during the class period.
