compute the annual percentage change in net income per common share-diluted (second numerical line from the bottom) for 1998–1999, 1999–2000, and 2000–2001.

Sun Microsystems (trends, ratios stock performance) (LO3) Sun Microsystems is a leading supplier of computer-related products, including servers, workstations, storage devices, and network switches.*

In the letter to stockholders as part of the 2001 annual report, President and CEO Scott G. McNealy offered the following remarks:

Fiscal 2001 was clearly a mixed bag for Sun, the industry, and the economy as a whole. Still, we finished with revenue growth of 16 percent—and that’s significant. We believe it’s a good indication that Sun continued to pull away from the pack and gain market share. For that, we owe a debt of gratitude to our employees worldwide, who aggressively brought costs down— even as they continued to bring exciting new products to market.

The statement would not appear to be telling you enough. For example, McNealy says the year was a mixed bag with revenue growth of 16 percent. But what about earnings? You can delve further by examining the income statement in Exhibit 4. Also, for additional analysis of other factors, consolidated balance sheet(s) are presented in Exhibit 5 on page 94.

  1. Referring to Exhibit 4, compute the annual percentage change in net income per common share-diluted (second numerical line from the bottom) for 1998–1999, 1999–2000, and 2000–2001.
  2. Also in Exhibit 4, compute net income/net revenue (sales) for each of the four years. Begin with 1998.
  3. What is the major reason for the change in the answer for Question 2 between 2000 and 2001? To answer this question for each of the two years, take the ratio of the major income statement accounts to net revenues (sales).

Which objectives did you develop to address these standards

Part 1: Find your State’s Academic Standards

Go to the Oklahoma State Department of Education, or the State Department of Education in your state of residence. Find Academic Standards in your state. In Oklahoma, these are under Services and Oklahoma Academic Standards. Choose a grade level and content area that you currently teach or would like to teach in the future. If you are currently teaching in higher education or Adult Basic Education, use the relevant standards and learning outcomes from your instructional context. Include a copy or link to these standards for your instructor to view.

Part B-For Assignment 1, you will write a professional growth plan on how you will use the skill of setting objectives for a classroom, district, or group of people that you currently work with or hope to work with in the future. Your objectives must be aligned with the standards you selected in Part 1 of Assignment 1. Adhering to APA guidelines, refer to your text and 1-3 outside resources in this plan. Be sure to cite your sources in the 500- to 600- word professional growth plan. Use these questions to guide your plan:

● Which standards did you choose to work? ● Which objectives did you develop to address these standards

(some states list objectives for you)? ● How will I use student-friendly language that clearly reflects the

content they will learn and the skills they will acquire? ● How will I ensure that objectives are linked to the Oklahoma

Academic Standards (or my state of residence) I have chosen? ● How will I include opportunities to determine students’ existing

knowledge and skills? ● In what ways will I reference objectives throughout the lessons?https://www.youtube.com/watch?v=yZJGcnYAOPs

● How will I post learning objectives, so they are in clear sight of students and parents?

● How will I know students understand the objectives? ● How will I connect activities to the learning objectives? ● How can I help students make connections between current

objectives and those of previous lessons, so it is clear how they all fit in the overall course or theme?

● How will I measure my progress as a teacher and the impact on student learning?

Part C-

Professional Growth Plan for Providing Feedback

For Assignment 2, you will continue to practice the skill of reflecting on your practice and write a professional growth plan that you will use to ensure you provide feedback to your students. Adhering to APA guidelines, refer to your text and 1-3 outside resources in this plan. Be sure to cite your sources in the 500- to 600- word professional growth plan. Use these questions to guide your plan:

● How will I be sure to provide feedback in a timely manner? ● How will I develop well-defined rubrics to evaluate students’ work

or performance? ● How will I ensure the feedback I provide is specific enough to help

students improve on their knowledge and skills, which align with the objectives I’ve chosen?

● How will I know that I am providing corrective feedback, rather than praise for effort?

● How will I help students develop their own feedback and correct their work until it is acceptable?

● How will I measure my progress as a teacher and the impact on student learning?https://d2l.macu.edu/content/enforced/55521-ED524309W122FS/Self_Reflection_and_Professional_Growth_Planning.pptx?_&d2lSessionVal=p5OS9bTVfONnD1WtwOz52r0idhttps://d2l.macu.edu/content/enforced/55521-ED524309W122FS/Self_Reflection_and_Professional_Growth_Planning.pptx?_&d2lSessionVal=p5OS9bTVfONnD1WtwOz52r0idhttps://www.edutopia.org/blog/tips-providing-students-meaningful-feedback-marianne-stenger
