U S DEPARTMENT OF HEALTH, EDUCATION, AND WEIFARE Office of Education Bureau of Research PREFACE The observation is not nev, neither is it unconfirmed by others, that there is a diversity of opinion as to what course content should be taught in introdectory college chemistry, how it should be taught, The primary contention now seems and what materials should be used. to be to consolidate these diverse opinions and practices and attempt to ascertain some order out of the controversies and diversity. A few investigations have been directed at determining the objec- tives of general college chemistry, the course content of introductory college chemistry, and motivation practices in first year college These noteworthy attempts have been meager when compared chemistry. to the prolific writing of chemistry educators describing the objec- tives and content of courses taught at their respective institutions of higher education. The Advisory Council on College Chemistry has described a course directed at the university level. The question is asked, "Do introductory college chemistry courses directed at the university meet with the needs of other institutions of higher learning, namely, the liberal arts colleges and the junior colleges?" The literature is abundant with articles showing a diversity of teaching practices but few solutions are offered. Fully cognizant of the damage of oversimplification and distortion of meaning, an attempt will here be made to consolidate these previous ii This is in order to ob- writings, suggestions, and research findings. tain a clear cut view of what current objectives, teaching methods, and materials are being used in the accredited colleges and universities. ACKNOWLEDGEMENTS The investigator is especially grateful to Dr. John W. Renner, the University of Oklahoma, for his perceptive and skillful guidance throughout the project and for his patience and assistance during the time in which the survey report was developed. The United State Department of Health, Education, and 'Welfare are accorded a kind thank you for their unceasing encouragement and their financial assistance in gathering the data for this survey. Finally, to my family and especially my wife, who each in his own manner contributed heartedly and unselfishly to the completion of the survey project, goes an expression of infinite thanks. iv TABLE OF CONTETTS Chapter Page PROBLEM AND OBJECTIVES 1 I.
