Learner ObjectivesLearner Objectives

At the completion of study, learners will be able to:– discuss research related to the use of spreadsheets in

teaching and learning.

– use terminology associated with spreadsheet tools.

– demonstrate knowledge of the organization and capabilities of spreadsheet software.

– examine ways to incorporate spreadsheets into teaching and learning.

– use spreadsheet software to create an interactive spreadsheet.

– examine methods of adapting and using spreadsheets with special learners.

– plan and develop a lesson that aligns with state curriculum and NETS•S standards and engages students in inquiry-based activities using a spreadsheet to solve problems.




Frameworks: What we knowFrameworks: What we knowSpreadsheets are computerized record-

keeping systems . . . used to generate numeric information and graphically represent it.

Research studies report that spreadsheets facilitate

– the development of organization skills.

– the development of problem-solving skills.

– describe relationships.

– supports the math curriculum at all grade levels.




Frameworks: What we knowFrameworks: What we know

Teachers use spreadsheets to

– Keep records

• Calculate grades

• Budget reports

– Design curriculum connections

• “interactive” spreadsheets can serve as practice or objective testing

– Create student assignments




Frameworks: What we knowFrameworks: What we know

Students use spreadsheets to

– Analyze data

• Population growth

• Income distribution

– Track data

• Rainfall

• Temperature

– Complete interactive spreadsheets on various curriculum topics for practice and/or assessment




Basics: Spreadsheet OrganizationBasics: Spreadsheet OrganizationOften referred to as a

worksheet . . . composed of columns and rows that intersect to form cells.

– Columns: vertical divisions.

– Rows: horizontal divisions.

– Cells: Intersection of a column and a row.




Basics: SS Organization, cont’dBasics: SS Organization, cont’d

– Cells have unique addresses consisting of the column name and row number: A1

– Active cell is the cell being used.

– Address box displays the active cell.

– Formula or data entry bar




Basics: Types of Data UsedBasics: Types of Data UsedOnly two types of data are entered

into spreadsheets. – Numeric data (values)

• Data that consists of numbers

– Alphabetic data (labels) • Descriptions or labels for the columns to assist the

reading of the spreadsheet




Basics: CapabilitiesBasics: CapabilitiesPerforming calculations are major

capabilities of spreadsheets. . . new terms are used . . .

– Range of cells

• Grouping of cells for mathematical calculations

• Uses a colon to represent missing cells . . . C1:C10

– Formula

• Set of instructions that the software follows to produce a value for a cell

• Must begin with = written in the formula bar

– Functions

• Most commonly used formulas such as sum or average

– Fill down & fill across

• A method used to copy the formula

• Shortcut IF same formula is needed (student grades)




Basics: CapabilitiesBasics: Capabilities

Formatting the data increases the ease of reading.

Formatting Methods for Spreadsheets

– Alignment

– Typeface, style, size

– Formatting the numbers: currency, decimals

– Insertion of titles, borders or patterns.

Creating Graphical Representations from Spreadsheet Data

After calculations, a chart or graph can be created to assist reading.

Common types:

Pie graphs: for parts of a whole

Line graphs: trend over time

Bar graphs: compare categories

NCES offers a great site for creating graphs and charts.




Constructing the SpreadsheetConstructing the Spreadsheet1. Open the software (some software has more features)

2. Enter the title and column and row labels

3. Enter the data

4. Enter the formulas and functions as appropriate

5. Check the calculations and adjust as needed.

6. Format the data to increase ease of reading.

7. Set print options.




Spreadsheets in the ClassroomSpreadsheets in the ClassroomSites provided here provide

information about using a database in the classroom. More is provided at On the Web: Spreadsheets

– Almost Everything You Need for Using Spreadsheets in the Classroom




Adapting for Special LearnersAdapting for Special Learners

• Vision Barriers– Adjust the actual worksheet display to accommodate

for small text or indiscernible contrast.

• Cognitive Barriers– Use the charting and graphing features to serve as

memory aids or to provide further explanations

• Physical Barriers– Keyboard adjustments include filter keys to adjust the

rate of key stroke acceptance– Sticky keys allow typing with one hand– On screen keyboards
