Miss Davis of the Colorado State Teachers College followed with an excellent discussion of the definite value of films in the classroom, and Mr. Perry, also of Colorado Teachers College, spoke on the value of visual aids in industrial education. The use of the Yale Chronicles in Junior High School was the subject covered by Dr. Fertsch of Yale University. Mr. Klemm, Superintendent of Colby, Kansas, schools, illustrated the use he has made of the motion picture in keeping a record of school activities. One morning's session was devoted to photography and cameras, many projectors being on exhibit. A complete report of the meeting is contained in the September issue of the Colorado School Journal. ♦ ♦ It is interesting to note that for the first time there is to be a section on visual education at the State Teachers Association meeting in Indianapolis. The authorities of the State Association have approved the section and the first meeting will be held on October 22 at the Indiana University Extension Building, Indianapolis. Symposium, Demonstration and Exhibit of Visual Aids in Chemistry At Buffalo, on September 1-4 last, was held a four-day conference devoted expressly to the use of visual aids in the teaching of chemistry. The meetings were under the auspices of the Division of Chemical Education of the American Chemical Society. The Society has been giving much study and investigation to visual methods for years past, and most gratifying results appeared at the Buffalo conference. The growing interest that the subject commands from such distinguished groups as The American Chemical Society is sound evidence of the future ahead of the visual movement. Chairman McGill, of the Committee on Aids to Visual Education in Chemistry, reports the program of a dozen sessions most interestingly. These were about evenly divided, half being demonstrations and half addresses, with attendance reaching 300 at some of the sessions. Every address was illustrated by slides, film-slides or motion pictures, and "sound" demonstrations played, an important part in the program. From the screen Dr. Millikan lectured on some of his work; Dr. Gordon and Dr. Baker, of the College of the City of New York lectured and experimented on "Water" before the eyes of the interested audience ; and Dr. Gordon, who appeared twice on the conference program, stressed especially in his demonstrations the possibilities of the "sound" film in the particular field of chemistry. A. L. Pouleur, of Wheaton College, discussing "Atomic and Molecular Structure as a Visual Aid in the Teaching of Chemistry," emphasized that chemistry students can be assisted in orienting themselves into the chemical point of view by suggestive models which aid visualization of chemical structure and the electron theory. Types of models suggested after tested classroom use in secondary schools and colleges are: 1. Frame models to show atomic structure with attachable electrons. 2. Models representing outer shell of any atom with transferable electrons to show compound formation with electron transfer. 3. Elemental models with electrons to show val ence exchange, molecular and compound formation and weight proportion in inorganic chemistry. 4. Flexible models of Hoff tetrahedronal carbon in benzene forms of Baeyer, Armstrong, Vaubel, and Sachse.
