## OPINIONS BY THE NUMBERS

ESTIMATED TIME TO COMPLETE: One 75 minute period

MODULE OBJECTIVES: Students will be able to:

• Select the best descriptor(s) for a given set of data
• Extrapolate information from an educational research article and explain the use of standard deviation
• Create displays of data (including box and whisker) electronically
• Use electronic tools to compute analysis of data set
CONCEPT(S) LEARNED IN THIS MODULE:
• Mean, median, mode, and standard deviation
STANDARD(S) ADDRESSED IN THIS MODULE (PRAXIS):
• Organizing, representing and interpreting data, mean, median and mode, using a computer and user-friendly software.
TECHNOLOGY-ENHANCED INSTRUCTIONAL STRATEGIES UTILIZED IN THIS MODULE:
• Locating current educational research articles on the web
• Participating in an interactive web based lesson
• Excel, Smart Board, graphing calculators and overhead projection device

### Module Overview

 Components Brief Description of Module Activities StudentGrouping Materials / Technology Engagement Students visit interactive web based lesson (www.shodor.org/interactivate/lessons/sm1.html is one suggestion) and answer questions about mean, median and mode. Students locate a web based research article and report on the statistics used in the article. In Pairs Computer with Internet Access Exploration Round robin discussion from engagement activities. Whole Class Explanation Teacher summary (instruction in) of the concepts learned. Using Excel to compute concepts and construct displays. Whole Class Excel Extension Constructing and using box and whisker plots on a graphing calculator. Individual Graphing calculators Evaluation Completed graph and individual analysis of data. Individual Word Processing and Excel

EXPECTED MODULE OUTCOMES:

• Students will be able to effectively use concepts of data display and analysis
PERFORMANCE-BASED ASSESSMENT OF MODULE OUTCOMES:
• Completion of electronic display and written analysis of data.
TEACHER NOTES:
• Students should be familiar with research articles that describe mean values. Hand out copies of research noting standard deviation of data in case this measure of dispersement isn't present in any of their found articles. Another possibility would be to post a chosen article to Janzebar Discussion Board prior to class time.
