Internet Learning Journal – Volume 4, Issue 1 – Spring 2015 To test significance of the hypothesis, samples were selected from two independent populations of textbooks. The samples were examined for evidence of scholarly references. Hypothesis testing was then conducted using a z-test comparing the proportions of the samples with scholarly references from each of the populations. The null hypothesis was that the proportion of scholarly references in the two textbook populations would be equal; the alternate hypothesis was that those textbooks with the more recent publication dates would have a higher proportion of textbooks with scholarly references than the earlier set of textbooks. Hypothesis testing procedure for testing two population proportions was used to examine if the two samples came from populations with an equal proportion of success. The null and alternate hypothesis were applied as follows: H 0 : proportion 1 (textbooks published from 1999 to 2002) = proportion 2 (textbooks published from 2003 to 2007) and H 1 proportion 1 (textbooks published from 1999 to 2002) < proportion 2 (textbooks published from 2003 to 2007). The level of significance with a margin of error of 0.05 was applied. A z-test to compare two sample proportions was applied with calculations from the data collected from each of the population samples. In order for the hypothesis to be accepted, the proportion of recently published textbooks must be greater than the proportion of earlier published textbooks with scholarly references. The results were tabulated using Microsoft Excel ® and MiniTab ® . Journalistic Prominence Budd (1964) conducted one of the first studies to survey a portion of the journalism profession to develop a device, the Budd Index, to measure newspaper reader attention score. Budd developed five criteria, and eight randomly selected editors rated the criteria in terms of importance. The five criteria included (a) multicolumn heads as opposed to onecolumn heads; (b) a story placed at the top of any page, or above the fold; (c) stories that run three-fourths of a column; (d) stories with an accompanying photograph; and (e) stories prominently published on the front page or principal department page. Budd (1964) removed the fourth criterion because it was not as relevant as the others, and the editors selected the fifth, second, and first criteria as the most important. The measurement device was an improvement on an earlier version developed by Teh-Chi Yu in 1949 (as cited in Budd, 1964). According to Budd, “The attention score, in its present form, is thought to be well suited for use in comparisons of publications similar in physical size” (p. 260). A cursory examination of 6 of the online teacher textbooks revealed that each was relatively the same 6 x 9 size or slightly larger. Thus, the closer immediacy terminology appeared towards chapter 1 in a textbook, based on Budd’s argument, the more the terminology would be noticed. 109 !
