Teacher Review (Based on classroom experience) Reviewer: Craig, Jun 17 2005 04:37:56:637PM |

Classroom use in Courses and Topics: Algebra II: Transformations of functions, Exponential Functions Trigonometry: Trig Functions |

Duration of classroom use: One Week |

What did students learn? Linear and exponential regression, residual analysis, superposition of functions |

What did students do with the resource? Students fit a curve to the "basic" flow of data (data points by year), then adjusted to fit the annual variation. |

How hard was it for students to use? Ok |

Other classroom comments: Very appropriate for my Algebra 2 students (we were using COMAP's Mathematics Modeling Our World, Course 3). |

Appropriate for: applications of a concept or technique, advanced investigations |

What math does one need to know to use the resource? Linear (and exponential) functions, trig functions. Statistics students might use inference about slope and confidence interval ideas. |

What hardware expertise does one need to learn to use the resource? None. |

What extra things must be done to make it work? Nothing. |

How hard was it for you to learn? Easy |

Explanation: The variety of file formats made it easy to select software that students knew how to use. |

Ability to meet my goals: Effective |

Recommended for: Algebra II: Parent Functions, Transformations of functions, Exponential Functions Trigonometry: Trig Functions PreCalculus: Functions Probability & Statistics: Inference |
