# STatistics Education Web (STEW)

STatistics Education Web (STEW) is an online resource for peer-reviewed lesson plans for K–12 teachers.

Statistics and probability concepts are included in K–12 curriculum standards—particularly the Common Core State Standards—and on state and national exams. STEW provides free peer-reviewed teaching materials in a standard format for K–12 math and science teachers who teach statistics concepts in their classrooms.

STEW lesson plans identify both the statistical concepts being developed and the age range appropriate for their use. The statistical concepts follow the recommendations of the Guidelines for Assessment and Instruction in Statistics Education (GAISE) Report: A Pre-K-12 Curriculum Framework, Common Core State Standards for Mathematics, and NCTM Principles and Standards for School Mathematics. The lessons are organized around the statistical problemsolving process in the GAISE guidelines: formulate a statistical question, design and implement a plan to collect data, analyze the data by measures and graphs, and interpret the data in the context of the original question. Teachers can navigate the STEW lessons by grade level and statistical topic.

##### Submit a Lesson Plan

Consider submitting your favorite lesson plans to STEW and encouraging your colleagues to do the same. STEW needs your participation to be a growing resource for statistics and probability teachers.

Lesson plans should follow the standard STEW template. Example plans include the following:

Send lesson plans to steweditor@amstat.org for publication consideration.

##### STEW Editor and Associate Editors

STEW operates similarly to an ASA journal. It has an editorial board consisting of an editor and associate editors. Authors submit proposed activities to the editor according to a template prepared for that purpose. The editor has the responsibility of determining which material meets the guidelines for posting on the website. Generally, this is done by passing the material to an associate editor for review and comments.

The ASA/NCTM Joint Committee on Curriculum in Probability and Statistics (K–12) is responsible for appointing an editor for the STEW. If you are interested in being an associate editor to review articles, send your name, email address, and a brief description of your qualifications to steweditor@amstat.org.
