teaching film is shown in the class room of a school Multiply this one classroom of stu dents by the hundreds who view such films each day and you realize the vast knowledge that is imparted and the value of visually bringing the world into the classroom There are some 5100 film titles in this Georgia State Department of Education Catalog films which are available at your request The teaching film is just one of many kinds of audiovisual aids available to teachers to make their teaching come alive for the stu dent Most children have inquisitive minds They want to learn Every avenue available to a teacher to impart this knowledge to answer these questions should be utilized The teaching film is one way of doing this It is my sincere hope that you will continue to utilize this service of the State Department of Educa tion The best film library is an empty one that is one where films are being requested and circulated rath er than collecting dust on storage shelves Help us keep our films dustfree and by so doing help your self to a better teaching method and your students to a new insight into the world they live in JACK P NIX State Superintendent of Schools Atlanta

shipments I TO GEORGIAS SCHOOL LEADERS AND CLASSROOM TEACHERS Every effort is being made to screen select and categorize films in order that each area of the curriculum in the schools of Georgia is covered Evaluation of the films now owned by the State is also being continued Older films which have been revised are being exchanged for newer editions Films which are no longer requested by the schools are being examined for future use or discontinuation In summary the AudioVisual Unit is attempting to keep films in the collection which are applicable and useable Films which are selected carefully and used properly present information to the students which teachers cannot pos sibly do in such a dramatic way The information also may not be possible to present to students in any other way The pres sure of time and the content to be covered necessitates careful selection of the films Thus teaching by film is just another means of presenting information to the students As with any other single method the usage of film requires its falling into a total plan of organizing for learning No one means of teach ing can do the job effectively for the teacher must have an overall plan Your assistance cooperation and suggestions in making the Film Library of the State of Georgia adequate and useable are sincerely desired Dr Claude M Ivie Director Division of Curriculum Atlanta
