crl-12542	Kuo, Frank F.	A Comparison of Six Versions of Science Library Instructions	1973	4	.pdf	application/pdf	1803	87	59	University students were ran- domly assigned to treatment groups, received verbal instruction with/ without supplementary visual illustrations and readings. A WIDE RANGE OF LffiRARY ORIENTATION has been reported in books and journals but there is little empirical evidence available to serve as a guide for a li- brarian to refer to in selecting visuals and media which will be most effective in facilitating student achievement of specific objectives.1 A randomized block design was em- ployed to investigate the relative effec- tiveness of different types of library in- struction as compared with the conven- tional library lecture at the Science Di- vision of the Portland State University Library.	cache/crl-12542.pdf	txt/crl-12542.txt
