History, Advantages, Disadvantages,
Student Misconceptions, Classroom Uses,
and Activities Involving Spreadsheets

2. Electronic Spreadsheets
 An electronic spreadsheet is analogous to
an accountant’s ledger sheet. It contains
rows and columns for entering character or
numeric data.
 Rows are arranged horizontally, while
columns are arranged vertically. The
intersection of both produces a cell. A
collection of cells is known as a range.

3. Electronic Spreadsheets
 Data is organized into columns and
rows in a meaningful way to convey
relationships and display information
used for both simple and complex
“number crunching.”
 The electronic spreadsheet is
a calculating tool.

4. Electronic Spreadsheets
 One of its tremendous advantages is its
ability to allow changes in data to affect
the entire spreadsheet. Changes in one
place are automatically applied to every
cell dependent upon the cell changed.
 Using the manual accountant’s ledger,
changes in one place had to be erased
and often, this produced errors of
omission.

5. Electronic Spreadsheets
 View the resources for information to see
more on the definition of a spreadsheet and
its organization.
 Another extremely helpful feature of a
spreadsheet is its ability to allow users to
create charts or graphs. Many packages
allow users to select from many different
styles of graphs and use these to provide a
visual representation of data and the
relationships between data.

6. Electronic Spreadsheets
 To numerical applications.
 To problems of description.
 To problems involving relationships.
 To problems involving analysis.
 To problems where large volumes of data
to be manipulated, saved, and compiled.
 To statistical applications.
Spreadsheets are calculating tools that can
be applied:

7. Electronic Spreadsheets
 Spreadsheets can be
used across the
curriculum in
education.
 They need not be
confined to only one or
two areas (i. e., math or
science).

8. History of Spreadsheets
 The electronic spreadsheet was created by
two Harvard Business School Graduate
Students in 1979: Daniel Bricklin and
Robert Frankston.
 With Bricklin’s idea and Frankston
programming, they created an electronic
accountant’s ledger to perform repetitive
calculations associated with case studies,
eliminate duplication, and use the
computer’s rapid computational abilities to
increase performance.

9. History of Spreadsheets
 This initial spreadsheet application,
VisiCalc, made its debut in 1979. It became
the prototype of many other programs that
were the first wave of electronic “number
crunchers.”
 VisiCalc was the forerunner for the second
generation of electronic spreadsheets. The
second generation came in 1982 with the
introduction of Lotus 1-2-3, which was the
first integrated software program.

10. History of Spreadsheets
 Lotus 1-2-3 blended three programs
together: graphics, spreadsheet, and
database to extend the usability,
functionality, and application of the
electronic spreadsheet.
 Lotus 1-2-3 was created for the IBM and
IBM compatible. Mitch Kapor founded
Lotus Development with Jonathan Sachs
in 1982. They created a more powerful,
user friendly, and integrated business
based spreadsheet tool.

11. History of Spreadsheets
 Third generation spreadsheet tools were
integrated with extended capabilities
(i.e., word processing, communications)
to make them even more useful. For
example, Symphony in 5 Movements
developed by Lotus Development, Inc. .
 Finally, the fourth generation of
spreadsheet tools increases the capacity
or size in terms of the number of rows
and columns available for use. *
*This is now only limited by the user’s RAM.

12. Common
Spreadsheet Packages
 ClarisWorks
 Microsoft Works
for Windows
 Microsoft Excel
 1-2-3 for Windows
 SuperCalc

13. Spreadsheet Software in
Teaching & Learning
 Spreadsheet are also called
worksheets. In Excel, many worksheets
can exist within the same workbook.
 Spreadsheets were the
earliest application
software available for
microcomputers.

14. Spreadsheet Software in
Teaching & Learning
 An integrated software package
includes a spreadsheet application,
used to help students manipulate data,
form conclusions, analyze, express
relationships, document findings, and
prepare material for distribution.
 Teachers use spreadsheets most
commonly for grade computation, the
development of instructional materials,
and lesson planning.

15. Spreadsheet Advantages
 Calculations and comparisons
 Modeling
 What-if-analysis
 Range estimation
 Projection
 Automatic
recalculation

16. Spreadsheet Advantages
 Time savings
 Creating charts
 Problem-solving
 Decision making
 Fill options
 Macros
 Real-world applicability

17. Disadvantages of
Spreadsheets
 Need for specialized software and hardware.
 Time for planning and practicing
 Development of meaningful and useful
applications takes energy and effort.
 Data can be incorrect, and must be reviewed
and verified for accuracy.

18.  Complexity surrounding formulas and their
arguments.
 Lack of detail in error messages often
causes user’s frustration and wastes time.
 Aspects of the spreadsheet can be applied
incorrectly, due to incorrect assumptions,
missing or inaccurate data.
Disadvantages of
Spreadsheets

19. Student Misconceptions
Using Spreadsheets
 Understanding
rounding versus
formatting.
 Creating formulas and
supplying arguments.
 Omitting parenthesis.

20. Correcting Student
Misconceptions
 Understanding rounding versus formatting.
Rounding changes the value in memory, while
formatting is merely a change in the value’s
appearance.
 Creating formulas and supplying arguments.
Be very specific. Provide at least three
examples of commonly used functions and their
associated parameters. Use the system’s help
facility as needed.

21. Correcting Student
Misconceptions
 Omitting parenthesis.
Follow the rule insisting that
an even number of
parenthesis is always used.

22. Student Misconceptions
Using a Spreadsheet
 Conversions between text
and numeric data.
 Placing data on one page.
 Printing formulas.

23. Correcting Student
Misconceptions
 Conversions between text and
numeric data.
Apply the appropriate functions and
distinguish between those used for
text and numeric data. Provide
examples and show consequences
of using inappropriate values.
 Placing data on one page.
Alter fonts, font sizes, margins, and
column/row designations.

24. Correcting Student
Misconceptions
 Printing Formulas.
Review formatting
and tool options and
provide examples.

25. Student Misconceptions
Using a Spreadsheet
 Absolute versus relative referencing.
 Creating lookup tables.
 Plotting non-consecutive series of data.

26. Correcting Student
Misconceptions
 Absolute versus relative referencing.
Show many examples of instances where data is
copied or moved. Explain fixed data or having the
move or copy reference an exact cell and its
contents versus allowing the spreadsheet to
apply values based on its position.
 Creating lookup tables.
Break this into three or more steps. Explain the
table, its position, referencing its contents, and
replicating the formula.

27. Correcting Student
Misconceptions
 Plotting non-
consecutive
series of data.
Show students how
this is done, and
indicate where they
should enter the
ranges of different
series.

28. Student Misconceptions
Using Spreadsheets
 Creating a formula.
 Understanding the difference between
a formula and a function.

29. Correcting Student
Misconceptions
 Creating a formula.
Make sure students know what symbol is
needed to begin to create a formula.
 Understanding the difference between a
formula and a function.
Explain to students that a function is a pre-
programmed set of instructions invoked by name
to perform a given task. A formula is a user-
derived set of operations used in computation. A
formula may or may not include a function.

30. Student Misconceptions
Using a Spreadsheet
 Manipulating and using
DATE functions.
 Applying percentages.
 Displaying values (###)
column widths.

31. Correcting Student
Misconceptions
 Manipulating and Using DATE
functions.
Thoroughly explain how DATE functions work
and provide examples of correct usage. Explain
how a date is represented, and whether or not it
must be formatted by the student.
 Applying percentages.
Explain the concept, supply manual examples,
and then, use the spreadsheet package to
simplify, aid retention, and shorten procedures.

32. Correcting Student
Misconceptions
 Displaying values (###) column
widths.
Change the size of the column, so that
more data can be displayed.

33. Classroom Uses of
Spreadsheets
 Discrimination.
 Attendance charts.
 Simulations.
 Comparisons.
 Performance
assessment checklist.
 Exploring mathematical
constructs.

 Spreadsheets are calculating tools that can
be used to solve problems involving data
analysis, numerical computation, projection,
estimation, interpretation, comparisons, and
