The following statistical analysis were used to address two research questions: To what extent are the EDAD candidates’ self-perceptions of their development of the knowledge, skills and dispositions different at the end of the leadership compared to their ability to apply the knowledge, skill and disposition when they first entered the program? Secondly, to what extent are the change of self-perceptions of knowledge and skills different from the change of dispositions? Repeated measure t -tests were used to compare the mean scores of candidates pretest and posttest scores. A two-way ANOVA was used to measure the difference in identified standards 5.0, 5.1, 5.2 and 5.3 related to ethics and the growth in disposition 17.

Results

Research question 1

Repeated measure t -tests were used to compare the mean scores of candidates Pretest and Post-test scores. Table 1 shows the pretest and posttest mean scores and standard deviations for the EDAD candidates responses to standard 5 and sub-standards 5 1a, 5 2a, and 5 3a.

Pre and Post Means and Standard Deviations
Pre Post
Mean Standard Deviation Mean Standard Deviation
Standard 5 (1-a) 4.07 0.98 4.95 0.25
Standard 5 (2-a) 3.87 1.17 4.96 0.19
Standard 5 (3-a) 3.51 1.17 4.96 0.19
Standard 5 Total 11.45 2.91 14.8 0.74

For Standard 5 (1-a) repeated measure t -tests reveal that there is a significant difference between pretest (M = 4.07, SD = 0.98) and post-test (M = 4.95, SD = 0.25), t (135) = 10.09, p <.001, d = 0.87. Similarly, for standard 5 (2-a) repeated measure t-tests reveal that there is a significant difference between pretest (M = 3.87, SD = 1.03) and posttest (M = 4.93, SD = .25), t (135) = 11.64, p <.001, d = 1.0. For Standard 5 (3-a) repeated measure t -tests reveal that there is a significant difference between pretest (M = 3.51, SD = 1.17) and posttest (M = 4.96, SD = .19), t (135) = 14.20, p <.001, d = 1.23. Finally, for Standard 5 (total) repeated measure t -tests reveal that there is a significant difference between pretest (M = 11.45, SD = 2.91) and posttest (M = 14.8 and SD = 0.74), t = (135) = 12.76, p <.001, d = 1.10.

Research question 2

In addition to measuring the growth of standards using repeated measure t-tests, a two-way ANOVA was used to measure the difference between the growth in identified standards related to ethics and the growth in dispositions. There was as a significant main effect for time (pretest/posttest), F (1, 268) = 143.19, p <.01 , η 2 = 0.53. There was a significant main effect for test (standards/dispositions), F (1, 268) = 53.62, p <.01, η 2 = 0.20. There was also a significant interaction between time (pretest/posttest) and test (standards/dispositions), F 1, 268) = 55.58, p <.01, η 2 = 0.21 .

Post hoc pairwise comparisons indicated that there was a significant difference on the pretest. Pretest scores for the dispositions ( M = 4.66, SD = 0.72) were significantly higher than the pretest scores for standards ( M = 3.82, SD = 0.97). However posttest scores were not significantly different and scores on both the standards and dispositions increased significantly from pretest to posttest.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
