Classroom use in Courses and Topics:

Algebra: Use of Variables, One Variable Equations, Functions / Relations, Linear Equations, Analyzing Linear Data, Linear Systems
Trigonometry: Trig Functions
PreCalculus: Functions, Linear Algebra

Duration of classroom use:

Multiple Semesters

What did students learn?

The book itself contains over twenty activites that encompass content across the curriculum. Linear, Quadratic, exponential, periodic functions are modeled in easy to follow labs. The write ups offer ready to use class material.

What did students do with the resource?

In all of the acitivties the students collect data using the CBL2 and then conisder function families that would be appropriate. In each case the labs follow up with algrebraic manipulation of the function families derived.

How hard was it for students to use?

Very Easy

Other classroom comments:

A great launching pad into the world of the CBL. Ready to use and written at an appropriate reading level for the students.

Appropriate for:

introduction to a concept, practice of skills and understandings, applications of a concept or technique, advanced investigations

What math does one need to know to use the resource?

Each activity could be used to introduce a new function, where the student wouldn't need much background. However another meaningful application is to use the activities after the particular function has been studied. This way students can reinforce any algebraic instruction set in a real world context. Ex: "After how many batteries does the voltage equal 5.6volts?" This has more meaning and power for students then "If y is 5.6 pleas find x"

What hardware expertise does one need to learn to use the resource?

CBL2 basic background, use of the TI-83, 84 calculator.

What extra things must be done to make it work?

Classroom routines are an important part of the use of technology. If students know ahead of time who is to collect materials, who has the appropriate software on the calculator, how their groups get together, etc. things will run smoothly.

How hard was it for you to learn?

Very Easy

Explanation:

The more you work with the CBL the better you get with them. Just remember that the first time is always the most difficult and that the kids will be better with the technology than you or I will be.

Ability to meet my goals:

Very Effective
