Define formal and informal assessments.

Measuring the academic performance of all students using both formative and summative assessments can provide a better picture of instructional modifications needed. In addition, sharing data with families can help them understand how to help their students at home.

For this assignment, create a 500-750 word brochure for families sharing information relating to assessment.

The brochure must:

  • Define formal and informal assessments.
  • Describe how each assessment type is used during instruction.
  • Include a minimum of two specific instructional examples for both formal and informal assessment (observation, questioning strategies, ticket out the door, etc.).
  • Identify the purpose of differentiating instruction and assessment to meet diverse learning needs.
  • Provide support resources and activities that can be implemented at home to support the assessment process for learning.

Support your brochure with 3-5 scholarly resources.

If you owned your own company and wanted to expand, would you choose to get your financing through debt, equity, or both?

Each week, you will be asked to respond to the prompt or prompts in the discussion forum. Your initial post should be 300 words long, and you should respond to two additional posts from your peers.

What Would You Do?

If you owned your own company and wanted to expand, would you choose to get your financing through debt, equity, or both? Why? What advantages or disadvantages do each offer?

What would you do to improve their structure if you could be CEO for a day?

Finance – Week 7 Assignment

Optimal Capital Structure

Write a 750 to 1000 word paper. In your paper include the following:

·  Explain the capital structure of the organization you have been studying this term. Do they rely more heavily on debt or equity? What are their structure weights (%’s)? How does this structure contribute to the overall risk of your firm? Do you feel they have chosen an ideal capital structure? What would you do to improve their structure if you could be CEO for a day?

Include a title page and 3-5 references.  Only one reference may be from the internet (not Wikipedia).  The other references must be from the Grantham University online library.  Please adhere to the Concise Guide to APA Style when writing and submitting assignments and papers.

Describe how you would communicate the assessment data and any intervention with families in order to support student achievement.

Allocate at least 3 hours in the field to support this field experience.

Pre-assessments can often provide critical data to guide your instructional content and strategies. With assistance from your mentor teacher, select three students from your field experience classroom who would benefit from an additional intervention strategy in the area of reading or math.

Based on recommendations from your mentor, select one state content area standard and create a pre-assessment that reflects the knowledge and skills needed to meet that standard. As an example, the assessment could be simple letter identification or asking questions about a book the students read to determine their understanding of the characters.

Implement the pre-assessment and analyze the results to determine the current performance level of each student. This information will be used to create and implement an intervention in the next topic’s field experience.

Use any remaining field experience hours to assist the teacher in providing instruction and support to the class.

As the deliverable for this Clinical Field Experience assignment, you will complete the following summary and reflection:

Write a 250-500 word summary of your pre-assessment activity, and the results from the implementation. Explain how this information will inform your future instructional planning for these students. Describe how you would communicate the assessment data and any intervention with families in order to support student achievement.

In 250-500 words, reflect on the importance of the pre-assessment process and analyzing the pre-assessment results to determine future instructional choices that would be appropriate for the students assessed. In addition, discuss the ethical use of data and how to make appropriate accommodations to assessments and instruction based on compiled data.

Document the locations and hours you spend in the field on your Clinical Field Experience Verification Form.
