Rubrics and Student Learning - Essay Example

Tables 1, 2 and 3 present quantitative data on the results of a paired sample t-test applied three pairs of art projects. Two-tailed paired samples t-tests were carried out using a significance level () of 0.05. In a two tailed test, it is hypothesized that two variables being considered have equal means. This hypothesis is rejected when the computed p-value, also known as the observed significance level is less than the hypothesized level of significance, which in this study is 0.05, signifying that the means are not equal and the difference between the two means are significant.

The variable with the higher mean is said to have a significantly higher mean than the other variable. Table 1 presents the results of the scores of Line Project 1 and Line Project 2. Line Project 1 was undertaken with no rubrics presented to the class prior to the project, while Line Project 2 was assigned to the students after clear and explicit expectations were clarified by a scoring rubrics. In this part of the analysis, even if a statistical software was used, the scores of Student No. 17 and Student No.

23 were manually excluded from the computations, since their scores on both projects were 0. 1Simple mean was computed without the scores of Student No. 17 and Student No. 23, since both students were not able to submit both projects. When the 0 scores of both students were included, the means were lower at 75.92 and 85.69 for Line Projects 1 and 2, respectively. 2Standard deviation was also computed without the scores of Student No. 17 and Student No. 23.When the 0 scores of both students were included, the standard deviations were higher at 27.

405 and 25.901 for Line Projects 1 and 2, respectively. As shown in Table 1, statistical analysis of the students’ score in Line Projects 1 and 2 revealed that the mean of the scores in Line Project 2 (92.83) is significantly higher than the mean of the
