In volume 78, number 2 of The Educational Forum, Tables 1 and 2 did not appear correctly in the published version of the article ìFolk Belief Theory, the Rigor Gap, and the Achievement Gapî by Bruce Torff, pp. 174–189. The corrected Tables 1 and 2 are shown below.

Table 1.  Means and Standard Deviations in CTBA Responses, by Group

Group	Variable
	HH		HL		LH		LL
	Mean	SD	Mean	SD	Mean	SD	Mean	SD
Expert^***	4.59	.45	4.20	.76	2.84	1.08	2.49	.76
In-service^***	4.44	.60	3.06	.59	4.19	.92	3.05	.79
In-service^**	4.59	.86	3.28	.77	4.11	.93	2.91	.67
In-service^*	4.62	.94	3.15	.78	4.10	.93	2.89	.79
Pre-service^*	4.60	.71	3.34	.71	3.99	.98	3.07	.67
Prospective^*	4.89	.59	3.33	.66	4.46	.76	3.41	.73

Note. CTBA = Critical Thinking Belief Appraisal; HH = high-CT activities for high-advantage students; HL = high-CT activities for low-advantage students; LH = low-CT activities for high-advantage students; LL = low-CT activities for low-advantage students.

Table 2.  Between-Group Differences: Probability Values and Effect Sizes

	Variable
Group	HH	HL	LH	LL
Pros-Pres^*	Pros > Pres	n.s	Pros > Pres	Pros > Pres.
	p < .05		p < .01	p < .05
	eta = .05		eta = .06	eta = .06
Pres-Ins^*	n.s.	Pres > Ins	n.s.	n.s.
		p < .05
		eta = .02
Ins-Exp^**	n.s.	Ins < Exp	Ins > Exp	Ins > Exp
		p < .0001	p < .0001	p < .0001
		eta = .48	eta = .36	eta = .15

Note. n.s. = not significant; eta = eta-squared statistic; Pros = prospective teacher group; Pres = preservice teacher group; Ins = in-service teacher group; Exp = expert teacher group; CT = critical thinking; HH = high-CT activities for high-advantage students; HL = high-CT activities for low-advantage students; LH = low-CT activities for high-advantage students; LL = low-CT activities for low-advantage students.
