=Stage 2 Determine Acceptable Evidence.=

Role: You are a statistician hired to collect and interpret data for a company. You will come up with at least one suggestion for the company to enhance their performance based on your analysis. Audience: The company's board members (represented by our classroom) Situation: Your job is to collect, organize and interpret from a company of your choice. Product/Presentation: You may present your data using Imovie, Garage Band or Powerpoint. Standards: Your presentation needs to include and introduction to your work, the data collected in a table, a graph of the data, an algebraic equation based on a regression analysis, proof of your conclusion algebraically and graphically with a detailed explanation, and at least one suggestion for the company based on your analysis. || •teacher observations •quizzes •test || •Word Sort - what do you know - what do you need to know •Frayer - what have I learned - what do I still have questions about || =Assessment Task Blue Print=

 * •group work (factored form, standard form, vertex form, moving parabolas, parameters)
 * Student Self-Assessment and Reflection**
 * Self-Assessment **(SA)** ||
 * •Pre-test/Post-test - write a one page reflection on comparison of results

What criteria are implied in the standard(s) understanding(s) regardless of the task specifics? What qualities must student work demonstrate to signify that standards were met? Quadratic models represent real-life situations. Characteristics of quadratic models may allow us to solve problems. || How can quadratic model be used to solve real-life problem. ||

 * Quadratic functions come in various forms.

//**Through what authentic performance task will students demonstrate understandings?**//
 * //**Task Description:**// **(T)** ||
 * You are an employee working for a company. You want to show the companies board members what they need to do in order to maximize or minimize some quantity. ||

//**What student products/performances will provide evidence of desired understandings?**//
 * Type II Product || Type of Presentation ||
 * •Imovie, Garage Band, or Power Point || •Introduction - Closure ||

//**By what criteria will student products/performances be evaluated?**// •Correct data collected •Graph correctly labeled, points plotted correctly, regression analysis correct •Correct regression equation •Algebra performed correctly to solve for max., min., intercepts •Analysis correct and complete •Suggestion follows logically from analysis • Product Quality • Technology Usage || Introduction of company and problem to be resolved Eye contact/posture Speak clearly Prepared/rehearsed ||  ||   ||
