Bullseye Models Using Excel And Geometer's Sketchpad, Heather Hoad Dec 2005

Bullseye Models Using Excel And Geometer's Sketchpad, Heather Hoad

Lesson Plans

Throughout this problem students explored the concepts of probability, percentage, and graphic representations of data. Students began by discussing the variables involved in playing a game of darts including: player skill level, strength, accuracy, coordination, gravity, etc. They then made hypothesized the number of darts out of 100 attempts that would land in each of the point value areas. During the remainder of the project, the class tested their hypothesis through a real life dart board model and an online dartboard simulation model. Students used a real-life magnetic dartboard to collectively gather data on 100 darts thrown and an online ...

Building Understanding: Using Math Journals To Increase Learning In An Intermediate Classroom, Paul Lawrence Jonasse Aug 2005

Building Understanding: Using Math Journals To Increase Learning In An Intermediate Classroom, Paul Lawrence Jonasse

Education and Human Development Master's Theses

Purpose

As an elementary school teacher I have watched my students struggle with new mathematical concepts: word problems, fractions, and increasingly difficult types of division have totally baffled many of my students. For the first several months of the school year most of my students did very well in math class, but they struggled with increasing difficulty as the concepts became more abstract. I have struggled to figure out ways to help them better understand. This project has grown out of our struggles with teaching, learning, understanding, and the working together to improve them all.

I entered into this research ...


Graphic Organizers Used As A Supplement To Science Textbooks Relating To Retention Of Scientific Facts In Fourth Graders, Bryana E. Zercie Jun 2005

Graphic Organizers Used As A Supplement To Science Textbooks Relating To Retention Of Scientific Facts In Fourth Graders, Bryana E. Zercie

Education and Human Development Master's Theses

This research attempted to answer the question, do graphic organizers used as a supplement to science textbooks increase student retention of scientific facts in fourth grade? The researcher collected data from 56 fourth grade students in an urban school to find out whether the use of graphic organizers after reading sections of the science textbook improved retention of scientific facts in fourth graders. The researcher used baseline science test assessments, reading levels of students, tests and quizzes after the use of graphic organizers, along with teacher and students surveys and interviews in this study. These pieces of data were studied ...


Teaching Literacy Strategies In Math, Terri L. Keenan Jun 2005

Teaching Literacy Strategies In Math, Terri L. Keenan

Education and Human Development Master's Theses

This study sought to determine the effectiveness of incorporating literacy strategies during math instruction. In distinct lessons, a class of sixteen students was given instruction in the strategies of using key words, visualization, and graphic organizers to solve word problems. The students rated the difficulty of the problems on a scale of "too easy", 'just right", and "too hard" both before and after the reading strategy lessons to assess if the use of the strategy changed their perception. The test-retest with equivalent forms method of estimating reliability was used to give a measure of stability and equivalence. A matched pair ...


Modeling Traffic Patterns Using Java, Kim Meek May 2005

Modeling Traffic Patterns Using Java, Kim Meek

Lesson Plans

The students plan to create a program that models the traffic during the day at Twelve Corners. Like the Marine Biology Simulation, the cars will be able to move forward and make turns according to the traffic patterns. They will use the MBS as a guide to develop their own program, which will enable an analysis of various traffic patterns. If it turns out that this is too lofty a goal, the students will be able to make modifications to the MBS to enhance its capabilities. Either way the students will learn the MBS by applying it to a real-world ...


Freshman Class Analysis Using Agentsheets, Kristen Frank, Brian Bizzigotti May 2005

Freshman Class Analysis Using Agentsheets, Kristen Frank, Brian Bizzigotti

Lesson Plans

The 2005 CMST Challenge Project is to survey the ninth grade class at East High School to see how many of their lives are affected by: pregnancy, drug use, crime arrests, family structure, student employment, and value of education. It was very hard to find the percentages of these factors for the United States. Therefore only certain questions will be used in the simulation. The results of the survey will be run through an agent sheet simulation to estimate the number of students that will successfully graduate using the data collected from the 2004/2005 freshman class.

In order to ...

Potential And Kinetic Energy - What's It All About?, Fayne Winter, Larry Bedgood, Susan Cooper Apr 2005

Potential And Kinetic Energy - What's It All About?, Fayne Winter, Larry Bedgood, Susan Cooper

Lesson Plans

Our investigation deals with the difference between kinetic and potential energy, and different situations that model those energies. Students needed to define kinetic and potential energy. In addition they needed to discover what the equations are to calculate these energies. Students were to investigate different situations where these energies are evident using various modeling technologies and design a tangible model they could use to assist in explaining the difference between the two energies. Once students designed these models, they needed to be able to explain where these energies exist in these situations using verbal explanations, mathematical equations, physical displays, and ...

Radioactive Decay Using Stella And Agentsheets, Annette Pennella, Dorothy Java Mar 2005

Radioactive Decay Using Stella And Agentsheets, Annette Pennella, Dorothy Java

Lesson Plans

The topic of our Challenge Project is the half-life of radioactive elements. We chose this topic for several reasons. The 8th grade curriculum includes the investigation of fossils and radioactive elements. Students often have difficulty understanding and relating to this natural event since it cannot be observed. They do not see how it affects their lives today. Mrs. Java and I decided to have at least two of the investigated elements be related to medical procedures. The students are able to relate what they have learned and see how this information has an impact on peoples’ everyday lives. The radioactive ...
