ACTIVITY: Interactive PowerPoint Tutorial Lesson on Condensing/Expanding Logarithms.

(This will be the first in a series of tutorials.)

My vision is to have teachers in the math department collaborate to create a site which provides assistance and examples on units which meet Missouri GLEs.

ANALYSIS: The tutorial will be available for students in Algebra II who fall into one or more of these categories.

• Students who demonstrate inability to condense/expand logarithmic expressions through class work. A score of less than 70% on relevant assignments will indicate a need for more directed practice.

• Students who were absent for the instructional presentation of the unit.

• Students who by their own request want extra guided practice.

• Students who wish to clarify a concept while doing an assignment and a teacher is not available

Purpose: To provide a step-by-step process to condensing/expanding logarithms. More than just providing the correct answer, the tutorial will allow students to check intermediate steps before proceeding. The tutorial will also model the correct order of steps. Even though a text provides students with the correct answer, it does not provide the intermediate steps which lead to that answer. Often students can make errors in the work and still get the right answer. This tutorial will help students avoid the “quirky error that actually works sometimes.”

Too often students try to move on to the next level of solving logarithmic equations without having functional understanding of the rules of logarithms. This lesson will help reach that understanding, thereby helping the student be more successful at the next level also.

I envision a website containing tutorials on several topics covered throughout the school year. Students will be able to access the tutorials from any computer and get detailed guidance for completing assignments or for test preparations.

Time: The student should be able to complete this and future tutorials in at most 30 minutes. Time will, of course, vary. Students may also access the tutorial for clarification of a property without completing the entire lesson. (the tutorial included here is a sample)

DESIGN & DEVELOP:

• Students will be able to condense/expand logarithmic expressions

• A PowerPoint interactive tutorial will be created and made available to students online.

• A problem is presented, the student condenses/expands the expression and checks the correct work for each step

• Students will self-evaluate at the end of the tutorial by condensing/expanding expressions and checking the answers.

IMPLEMENTATION:

Ideally, the program could be available for students from their homes or in the

classroom. In the nonclassroom sites, it is unlikely an instructor will be present.

In this type of tutorial there is always the chance that the student will just click on the next step without actually working the problem. However, students who access the tutorial are doing so of their own choice. Their motivation should be high. One motivational technique to encourage students to use the tutorial will be to include in each lesson a difficult problem from the text assignment. By including one of the difficult and “dreaded even-numbered” problems, students will access the site for that problem. Once familiar with the site they will be more apt to return when they need assistance. The tutorial needs to be short and easy to navigate.

EVALUATION:

• Student success will be measured through written assessment. A score of 70% or better will be considered functional understanding.

• Students will be surveyed after using the tutorial to determine ease of use and motivational value. Students will be given bonus points for the survey. This will encourage students to access the site and become familiar with its potential as a tool for understanding. As more tutorials are available, the extra credit will be limited to a certain amount per quarter.

• If successful, more topics will be added to the format. They will be organized by chapter and section of text.

• Designed in the summer, I do not have students to try the tutorial. Once it is available, improvements will be made based on student surveys and student success. I did have students who are beyond the Algebra II level run through the tutorial. They had no difficulty following the directions. However, their math skills are too advanced to experience any improvement from the presentation.

Condensing logarithms is the Missouri GLE:

MA4 1.6, 1.10 VIII.c&d, IX.b

Apply properties of logarithms to simplify expressions or solve equations.
