With the fundamental position of the committee that "learning is a continuous and gradual process which begins in infancy and continues throughout the period of life" without sudden and relatively abrupt changes, the writer is in complete sympathy, as also with the conclusion that "beginning with the elementary school and continning through the secondary school we should have a continuous andcorrelated program of science." We are furthermore in sympathy with the program of sciencz submitted for

This 366-page report on "A Program far Teaching Science" is the outcome of two years' work of the Society's committee on the Teaching of Science, which is of six professors of education or of the natural sciences in teachers' colleges or in the departments of education or universities. Its chairman is S. Ralph Powers, Professor of Natural Sciences, "A. Grades Seven to Twelve Teachers College, Columbia University, Seventh and eighth years-Science, New York City.

ence, but also some real apprehension "of the methods of scientific study and investigation and some appreciation of scientific attitudes." The acceptance of this program means the end of general science as a collection of bits of information about familiar happenings, the all-too-common form i t now takes. It should be frankly recognized that we have few teachers sufficiently grounded in both biological and physical science to teach adequately this cot;ception of a really generalized science. Pending the preparation of such teachers, schools might well retain biology in the ninth year, for the teaching of which there is now a supply of amply equipped teachers. I t is only as we come to this statement on page 10 of the report that we part company: "Definable educational values from

tions in ihheir own experiences; (2) an ability to interpret the natural phenomena of their environment; (3) an appreciation of scientific attitudes tllrough an undrrstanding of, and ability t o use some of the methods of study that have been used by aeative workers in the field of science." The writer of this review is not a scientist nor even a teacher of science. He is merely a superintendent whose work is t o do what he can for the improvement of teaching in the high schools of New York City. I n this capacity he acted some four years ago as the monthpiece of the 600 teachen of science in those schools and as editor set forth their views in a report bearing the title "Teaching Science as a Way of Life." These teachers of science meet monthly in four organizations-the Biology Teachers Association, the Association of Teachers of General Science, The Physics Club, .and the Chemistry Teachers' Club. The activities and interests of all these science b c h e r s are deared through "The Standing Committee on Science" made up of reptesentatives of these groups and offi+ally recognized by the superintendent

in charge of high schools and consulted by him on all policies, courses of study, methods of teaching, and other matters having t o do with science teaching. This standing committee probably represents the l a r ~ e s unified t body of secondam science teachers in this country, possibly the most professionally minded and hesttrained. In the following comments, the writer voices the point of view of this Standing Committee on Science, and, therefore, the paint of view which animates the teaching of science in the high schools of New York City, a point of view which may fairly be represented as the official point of view or philosophy of education of the system of high schools. "Our teachers accept the values put forth by the Committee as desirable but as not attaining t o the full measure of the values that society can and should demand of the teachen of science. They believe it is incumbent on them to build up in their pupil? not merely a n appreciation of scientific attitudes h t some of the ilttitudes thr~welvrs.

We bbeliee in subjects and in the mastery of subject matter not as ends in themselves but as means to an end, that end being the most complete development of the capacities of each boy or girl possible under the conditions in which we work. We therefore view the study of biology, physics, chemistry, general science as means of developing in the boys and girls certain well-defined, consciously striven for qualities, habits, and attitudes. We realize that in the case of most pupils the subject matter, even tllough seemingly well mastered, will not long remain a functioning possession of these pupils, but we hope a t least that the changes in ideals, habits, and attitudes effected in the boys and girls by teachers who hold to this point of view will be in much greater degree enduring.

The Committee in Chapter I seems to hold this conception, but only in part, for on page 3 we read, "It is the aim of the school to provide the experiences which will make possible the most efficient growth in learning. Effective accomplishment of this aim is conditioned upon the ability of the curriculum worker to make available to the children of succeeding grade levels the learning experiences which are appropriate for continuous mental growth." The New York High-School Teachers of Science hold that it is not merely mental growth, not growth in Learning only, but the growth of the entire child, the enlargement of his physical, moral, esthetic, and spiritual self that we conceive to be the task of the schools and most especially of the science teachers of our schools. They are not content with "facilitating the study of those large truths of science that have within them the greatest potentiality for influencing human thought and action" (page 6) desirable as that is. They are not satisfied unless they a t Least attempt "to develop a sense of the wonderful and the beauiiIul in nature"-"to get an emotional response from their pupils that will show they are living in a larger world in the sense of Plato's magnificence of mind'-% develop the scientific imagination"-"to develop that intellectual curiosity that results in individual efforts for knowle d d - " t o develo~scientific sce~ticism" -"to build up openness t o new ideas and willinmess Dresent judg- t o chanae . . merits'-"to emulate great scientists in contributing freely t o the common goodu-"to develop the ability t o test the truth of a conclusion"-"to develop the increased appreciation that springs from power of accurate observation."

feared such a reasonable statement of transfer as would be involved in an endorsement of the general aims of science teaching we have cited. It is unfortunate, as stated earlier, that the makers of the report were all professors in teachers' colleges. The experience of some progressive secondary teachers of science on the committee would have forced upon them a broader conception of the function of a science program in our schools. They might have been made t o realize that the task entrusted t o them was not to rear a beautifully logical science mechanism for the production of scientists and science teachers but t o formulate a plan of science teaching which would contribute to the richest, most complete possible development of every pupil, no matter what the calling he is t o pursue. The Committee, due again to its composition, has overstressed the validity and importance of "scientific educational experimentation and- testing" and has seemingly been unwilling to attach much, if any, value t o qualitative evidence based on the experience and reasoned judgments of teachenr: As no precise appraisal of the degree of success in realizing the objectives cited above is a t present possible, the Committee has been unwilling t o accept such objectives as basic in a program of science teaching and in the judgment of the writer in so doing has removed the chief iustification for such a time-consuming program from the primary school to the college as is advocated bv the Committee. Too few boys and girls will ever make direct use of the science they have studied t o warrant the universal study of science if the objectives of that study are conceived merely in increasing mastery of its subject matter and technic and not in the changes wrought in ideals, and outlwk, in qualities, habits, and attitudes, which are the very essence of education. The report contains valuable material on miticisms of current practices in scientific teaching, on contributions of
