To determine the comparability of the two groups examined in this study, the students’ learning index scores on the previous year’s end-of-year state mandated tests in reading and math were used and compared by an independent samples t-test. To establish growth on the state mandated tests in reading and math, the difference between each child’s third and fourth grade learning index score was calculated. A learning index score indicates how far above or below a student is from the passing standard and is used to show annual progress. To compare the content knowledge of the two groups, a composite score for each student was derived for both the pretest and the posttest and a two-way repeated measures ANOVA was conducted to examine differences of the scores across the two groups.
The Estes Attitude Scale (Estes, Estes, Richards, & Roettger, 1981) scores for each child were summed to obtain a single attitude score for each child. The scores were compared using an independent samples t-test. To provide an accurate and consistent confirmation of the characteristics in each classroom, the learning process, and progress of the students, classroom observations, field notes, videotapes, and interactions were compiled to identify similarities and differences in the methods.
Findings
The purpose of this study was to examine the classrooms of two educators who have the freedom to teach to their strengths. This study looked at the children in these classrooms to determine the areas where both classes score equally as well, along with areas in which the
students’ achievement differed. The study also evaluated the students’ attitudes about school to determine if differences existed.
The means on the pretest and posttest for the inquiry class are *=5.94, SD=2.304, n=17, and * =11.94, SD=1.249, n=17, respectively. The means on the pretest and posttest for the deductive class are *=3.765, SD=2.047, n=17, and * =5.118, SD=3.498, n=17, respectively. The pretest for the inquiry class, the pretest for the deductive class, and the posttest for the deductive class was normally distributed W(17)=.940, p=.316, *=.01, W(17)=.906, p=.085, *=.01, W(17)=.947, p=.412, *=.01, respectively. However, the posttest for the inquiry class was not normally distributed, W(17)=.816, p=.003, *=.01. A data transformation was necessary to change the distribution of the scores. A reflection and a square root transformation was applied and using the skewness test for normality, the scores were normal, where z=1.12. The new mean for this variable was 1.3769, and the standard deviation was .41620. Mauchly’s test of Sphericity was used to assess equality of variances, and the greenhouse-Geisser statistic with *=1 was used. Variances are homogenous.
Using the Wilkes’ Lambda, the interaction between the class groups and the tests was significant, F(1,16)=48.956, p<.001, *=.05. Simple main effects were assessed using a paired samples t-test. A Bonferroni adjustment was applied to adjust the type I error, *=.025. There were significant differences found between both the pretests and the posttests, t(16)=2.749, p=.014, *=.025, and t(16)=-4.458, p<.001, *=.025, respectively.
As a follow-up to differences in the pretest scores, a new test was run looking at only the growth from the pretest to the posttest between the two classes. The growth score was calculated by subtracting the pretest scores from the posttest scores. This was done for both the inquiry class and the deductive class. An independent samples t-test was then conducted to determine if there were differences in the growth scores. The independent samples t-test has two model assumptions, normality and equal variances. The growth scores were normally distributed, W(34)=.974, p=.586, *=.01, and variances were equal, FLevene’s (1,32)=.013, p=.909, *=.01. A large practical significance was calculated, d=1.72, which indicated that within sample differences were significant.
Data were collected on both the third grade TLI scores and fourth grade TLI scores for both classes. To determine if there were differences between the two classes, an independent samples t-test was conducted. The scores were collected as separate scores for reading and math. For the purpose of this study, the reading and math scores were combined to create a total reading and math TLI score. In order to calculate a growth score, the fourth grade total score was subtracted form the third grade total score. The mean for the inquiry class was 6, SD=2.693, n=17, and the mean for the deductive class was 1.35, SD=2.737, n=17.
The independent samples t-test has two underlying assumptions that were addressed before analysis began. The growth score was normally distributed, W(27)=.964, p=.458, *=.01. Equality of variances was also checked and found to be acceptable, FLevene’s (1,25)=4.162, p=.052, *=.01. The mean for the inquiry group was 5.933, and the standard deviation was 9.339, n=15. The mean for the deductive group was 9.333, and the standard deviation was 17.469, n=12. There was a statistical difference between the inquiry class and the deductive class, t(32)=4.990, p<.001, *=.05. A small practical significance was calculated, d=.25, which indicated that within sample differences were not very significant.
An independent samples t-test was conducted to detect any differences between the two classes. Attitude scores were normally distributed, W(36)=.963, p=.275, *=.01. Variances were also checked and found to be acceptable, FLevene’s (1,34)=2.083, p=.158, *=.01. The mean for the inquiry group was 59 and the standard deviation was 10.302, n=17. The mean for the deductive group was 61.68 and the standard deviation was 12.966, n=19. There was no statistical difference between the inquiry class and the deductive class, t(34)=-.682, p=.500, *=.05. A small practical significance was calculated, d=.23, which indicated that within sample differences were not very significant.
Findings and Conclusions
The purpose of this study was to examine the classrooms of two educators who have the freedom to teach to their strengths. This study looked at the children in these classrooms to determine the areas where both classes score equally as well, along with areas in which the students’ achievement differed. The study also evaluated the students’ attitudes about school to determine if differences existed.
The teaching method used in the classroom was found not to effect how the students performed on state-mandated tests. The teaching method used in the classroom did not affect students’ attitudes toward the three academic areas of math, reading, and science. In an era of especially intense accountability, this information has application for school administrators. School leaders are often in a quandary about which methods to endorse and encourage in their buildings. This study indicates that the method, whether inquiry or deductive, is not the issue. The method that worked best for the individual teacher did not affect students’ state assessment scores.
