Page 49 - It is the conclusion of the author, then, that instead of curtailing the work in chemistry in our high schools we increase the efficiency of our teaching by taking advantage of methods of presentation requiring less time and material in developing certain skills and abilities, in order that more examples and a wider range of subject matter may be presented in that same available time.

Page 46 - ... chemistry. . . . On the whole the intelligent pupil will succeed no matter what method of presentation is used in the laboratory and ... his success will be greater than the usual success of those of lower intelligence. In the eight classes in which intelligence scores of pupils were available, the pupils of medium and lower intelligence seem to profit on the whole a little more from a good demonstration than when they themselves perform the exercises individually, when success is measured as...
Page 46 - pupils of medium and lower intelligence ... do not as a whole do quite so well when working in groups of two as when working individually, but the difference is very slight." Johnson28 compared the relative achievements of pupils in groups of four or five when they, themselves, manipulated the apparatus (and also when they observed the demonstrations by the teacher) with those of other pupils working...
Page 49 - ... and lower intelligence seem to profit on the whole a little more from a good demonstration than when they themselves perform the exercises individually, when success is measured as indicated above. It is Carpenter's analysis of the significance of his findings, however, which is of chief interest: It is not the opinion of the author that individual laboratory work in high-school chemistry should be eliminated, or that buildings in future contain no laboratories, but rather that a larger number...
Page 26 - ... Further discussion of the arrangement of science rooms seems unnecessary, for equipment and plumbing are matters which school authorities must settle for each individual case. This further point, however, ought to be emphasized : It is a serious menace to the health of the students to work in a chemical laboratory which is not provided with adequate means for carrying off the fumes and keeping the air SPECIAL ROOMS. 35 pure and clean. Therefore, directly above the tables upon which the experiments...
Page 49 - In summarizing his study the author recommends that a larger number of exercises be offered by demonstation by the teacher and a smaller number be performed by the student, but that the increase in the number of demonstration exercises be greater than the decrease in the number of exercises performed whether by groups or individuals...
