P. S. E. A. The Science Section of the Pennsylvania State Education Association
served a science dinner, cafeteria style, a t the William Penn High School a t Harrisburg on December 20th. This dinner was one of the first steps in the organization of a state science association. Speeches were made by a number of the members: First, on the plan and, second, on the best methods of organization and procedure necessary to effect the same. I t wasunanimously voiced that there was a specific need for a strong state science association made up of units corresponding t o the convention districts with these units united and centralized into a state organization, the meetings of which would be held in conjunction with the P. S. E. A. It was voted to have a committee of seven, one from each of the present convention districts of Pennsylvania, appointed by the president of the Section to perfect such an organization. C. A. Gorgas of Peabady High School, president of the Langley Association of Science Teachers, pledged the loyal support and active cdperation of that association in the movement. Professor Gerald L. Wendt, Dean of the School of Chemistry and Physics, Pennsylvania State College, and Chairman of the Pennsylvania State Essay Committee, gave a brief talk on the importance of the participation of all science students in the American Chemical Society's prize essay contest. Dr. W. L. Eikenberry of the East Stroudsburg State Normal School presided.
Teachers Need Ethics Code. The need of a national ethics code for teachers was stressed by Prof. Ward G. Reeder of Ohio State University, speaking before the American Association far the Advancement of Science. Prof. Reeder pointed out that teaching is the only profession still lacking such a code. A number of state teachers' associations have adopted codes of ethics but a national code would be of greater value to the profession, Prof. Reeder stated. In arguing for a national code of ethics for teachers be said that "such code would give the profession of teaching more dignity and respect both on the part of the general public and of teachers; moreover, such code would do much to eliminate any unprofessional practices among teachers, since it would serve as a guide to t h e novice and unsophisticated practitioner and would be a silent warning to one who was tempted to act unprofessionally."-Science Service
