Lpi results

LPI results are distributed among six categories. Kouzes and Posner identified Five Practices of Exemplary Leadership® (Model the Way, Inspire a Shared Vision, Challenge the Process, Enable Others to Act, and Encourage the Heart) that contributed to each resident’s summative scores.

Paired samples t tests were conducted to evaluate the impact of the instructional leadership program on students’ scores on each of the LPI’s Five Practices. The results are:

Model the way

There was a statistically significant increase in LPI scores under the Model the Way Practice from the pretest ( M = 47.20, SD = 6.16) to the posttest ( M = 50.65, SD = 6.13), t (23) = 3.29, p =.003 (two-tailed). The mean difference in LPI scores was 3.44 with a 95% confidence interval ranging from 1.28 to 5.60. The value of Cohen’s d statistic is .79.

Inspire a shared vision

There was a statistically significant increase in LPI scores under the Inspire a Shared Vision Practice from the pretest ( M = 42.17, SD = 9.03) to the posttest ( M = 47.83, SD = 6.46), t (23) = 3.14, p =.005 (two-tailed). The mean increase in LPI scores was 5.65 with a 95% confidence interval ranging from 1.93 to 9.37. The value of Cohen’s d statistic is .88.

Challenge the process

There was a statistically significant increase in LPI scores under the Challenge the Process Practice from the pretest ( M = 43.17, SD = 8.96) to the posttest ( M = 47.35, SD = 7.94), t (23) = 2.55, p =.018 (two-tailed). The mean increase in LPI scores was 4.17 with a 95% confidence interval ranging from .78 to 7.56. The value of Cohen’s d statistic is .66.

Enable others to act

There was a statistically significant increase in LPI scores under the Enable Others to Act Practice from the pretest ( M = 49.22, SD = 5.23.03) to the posttest ( M = 51.74.83, SD = .56), t (23) = 2.26, p =.033 (two-tailed). The mean increase in LPI scores was 2.52 with a 95% confidence interval ranging from .21 to 4.83. The value of Cohen’s d statistic is .68.

Encourage the heart

There was a statistically significant increase in LPI scores under the Encourage the Heart Practice from the pretest ( M = 46.39, SD = 7.32) to the posttest ( M = 49.87, SD = 6.82), t (23) = 2.49, p =.021 (two-tailed). The mean increase in LPI scores was 3.48 with a 95% confidence interval ranging from .58 to 6.37. The value of Cohen’s d statistic is .67.

Lpi summative scores

There was a statistically significant increase in LPI scores in the summative LPI score from the pretest ( M = 45.63, SD = 6.71) to the posttest ( M = 49.49, SD = 6.06), t (22) = 2.95, p =.007 (two-tailed). The mean increase in LPI scores was 3.85 with a 95% confidence interval ranging from 1.15 to 6.56. The value of Cohen’s d statistic is .81.

Evaluations

Mentors completed an evaluation of the redesigned program near the end of the semester. The mean scores of their survey responses are included in Table 1.

Mentor Principals’ Evaluations of the Redesigned Instructional Leadership Program
Statement Mean Score
1. My orientation session to the program was helpful. I left the meeting at USA with a reasonably clear idea of my responsibility as a mentor. 3.87
2. Program requirements (knowledge and ability statements) were clear. 3.98
3. I met with my resident often enough to evaluate his/her performance while he/she was assigned to my school. 3.92
4. I was satisfied with the frequency of visits to my school by the USA program supervisor. 3.90
5. The Leadership Practices Inventory (LPI) seems to be a helpful formative assessment of Residency performance. 3.72
6. My assessment of the residency? 3.89

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
