Informal Discussion : ' Should the attitude of 

 the student be that of discoverer or verifier ? ' ' Is 

 consultation of two or more students on a labo- 

 ratory experiment disorder ? ' ' Is it certain that 

 some experiments that require several hours to 

 perform are more valuable to a student than the 

 time spent in reading ? ' ' How many times is it 

 profitable for a student to perform certain experi- 

 ments for greater accuracy, for example, finding 

 the latent heat of vaporization of water ? ' ' Must 

 the student record every experiment?' 'Should 

 work with scales and calipers be done in advance 

 for the purpose of learning the use of the instru- 

 ments, or should the operation be done for the 

 first time when use requires it ? '
