# Project #46340 - Statistics

Â

Â

Rationale:

In mathematics courses at the college level it is important to learn how to read the textbook. In several future courses, the content in the book may not be covered in class but is fair game for the test. Unfortunately, there is often so much information simply reading the text is difficult. A math reading journal will help you organize the important concepts and learn more from the textbook. (I still use this system for my graduate level classes.)

Â

Assignment:

1.Â Â Â Â  Type out your journal in MS Word. (I may not be able to read other formats.)

2.Â Â Â Â  Create a separate page for each chapter of the book.

3.Â Â Â Â  At the top of the page, copy the title for the chapter. Under the title, include the following notes:

a.Â Â Â Â  Write a 2-3 sentence summary of the chapter. (5 points)

b.Â Â Â Â  Define any words in bold. You can either use the context of the text or the glossary (5 points)

c.Â Â Â Â  On blackboard, I will give you a question about the chapter that is meant to be answered in 2-3 sentences. Â (5 points)

d.Â Â Â Â  Work out an example that best represents the chapter and explain each step. (5 points)

Â

Each part will be collected through blackboard and graded separately on the due dates listed below. Each chapter is worth 20 points towards the reading journal grade.
