Technology integration is a process. In order to be 'sold' on
technology, teachers need to experience (not just be told or shown)
the ways computer technologies can help them save time in the
classroom, be more productive, and provide new opportunities for
communication and information access. After becoming comfortable
using gradebook software, email, word processing software, and
surfing / searching the web, a logical 'next step' for educators is
to begin using spreadsheet software to improve administrative tasks
and communication. This article describes ways spreadsheet software,
specifically Microsoft Excel, can be used to manage lists within an
educational context. Steps for Excel in this article apply to the
following versions: Excel 2000 for Windows, and Excel 2001 for
Macintosh. A linked copy of this article is available on http://www.wtvi.com/teks.
Spreadsheet Basics
Every teacher is required to manage student data in some way.
While word processing software can certainly streamline the creation
and management of text documents, a spreadsheet offers advantages
over word processors that should not be overlooked. Spreadsheet
software was first developed in 1961 by Professor Richard Mattessich,
but did not become widely used until 1978 when 'VisiCalc' was created
for the Apple II.1 Despite this
relatively long history (in the relative timeline of computing), the
ability to create computer documents which perform simple (or
complex) mathematical formulas remains unrealized for many
educators.
According to dictionary.com,
a spreadsheet is 'A piece of paper with rows and columns for
recording financial data for use in comparative analysis.' People
often think of spreadsheets only in this financial context, for
creating budgets or other reports requiring data calculations. Yet
spreadsheet software, including the widely used Microsoft Excel
program, offers much more than financial calculation potential.
A computer spreadsheet is composed of rows and columns which
divide the document into unique cells. In Excel, columns are assigned
alphabetical letters starting with A through Z. After column 26, a
preceding 'A' is added to the column titles: AA, AB, AC, etc. Rows
are numbered in ascending order from 1 on up. When explaining
spreadsheets to students, it is helpful to ask how many are familiar
with the game 'Battleship.' In the game, players identify where their
ships will shoot in search of enemy targets by calling out grid
coordinates like those in a spreadsheet: "Fire on D5." "Miss!" "Fire
on B2." "Hit!" An understanding of the coordinate grid used in
playing 'Battleship' is transferable to a computer spreadsheet.
In addition to the use of fields and a coordinate grid,
spreadsheets are distinguished from word processors by the FORMULA
BAR. Because spreadsheet cells have a defined width, novice users
often wonder how more information can be entered or edited into such
a small space. The answer is by using the formula bar, which (in
Excel) can be made visible or hidden by selecting its name from the
VIEW menu.
Each field in a spreadsheet can be formatted in a variety of ways.
After selecting a cell or group of cells, from the FORMAT menu in
Excel choose CELL. Alternatively, right click (Windows) or control
click (Macintosh) and choose FORMAT CELL to bring up a tabbed menu.
Under the GENERAL tab, cells can be formatted to contain text,
numbers, dates, times, percentages, currency amounts, or fractions.
The default format type for a cell is GENERAL, which means no
specific number format is identified. If the number format is
selected, the number of shown decimal places can be specified, and
whether a 1000 separator (comma) should be displayed.
To select more than one cell in Excel at the same time, (before
applying a format change for example):
- Click on a cell in the corner of a group of cells you want to
select.
- Hold down the shift key.
- Click on a cell in the opposite corner of the group of cells
you want to select.
- Apply the desired formatting or other commands, and all
selected cells will be affected.
This procedure works when copying and pasting groups of cells as
well, which can be handy.
Managing Lists
Making a budget from scratch using a spreadsheet can seem
complicated and intimidating to a novice user, and is probably best
left to customized financial software like Quicken. Creating and
managing a list of some type with a spreadsheet, however, is a fairly
straightforward process, and is a good way to get comfortable with
Excel.
Step 1: Enter Column Headings
Begin your list by adding headings in the first row of the
spreadsheet for each category (field) of information the list will
contain. For a class list, these could include last name, first name,
address, city, state, zip, phone, parent name, etc. It is a good idea
to separate fields like first and last names into different columns,
because this can provide more flexibility if the spreadsheet is used
later within a mail merge. It also provides more flexibility when
list data is sorted.
After entering information in a cell, press the TAB key to record
that information in the cell and move the cursor to the next
cell.
Step 2: Enter the Data
After the column headings are entered, type the data into the
cells below. Each row of the spreadsheet should contain information
about a single entity. In the case of a class list, each row will
contain data about one student. Do not worry about entering data in
alphabetical or another order. The list data can be sorted later (see
Step 4.)
Step 3: Format the Cells
 Most
likely, some of the columns and rows in your spreadsheet will need to
be resized. This can be done in a variety of ways, including use of
the FORMAT menu once the appropriate cell row or column is selected.
A graphical way to resize rows and columns is to move the cursor
between two column or row headings until it changes from an icon that
looks like a plus symbol, to an icon that looks like a horizontal
line with arrows extending up and down from its center. Click and
hold down the mouse button, and drag the row or column to the desired
height or width.
If
desired, text can be formatted to 'wrap' within a cell so a string of
text wider than the column width is visible within the cell borders.
To do this:
- Select the cell(s) to format by clicking or shift-clicking on
them.
- From the FORMAT menu, choose CELLS.
- Click the ALIGNMENT tab, and under TEXT CONTROL click WRAP
TEXT.
Many
other advanced formatting settings are available within the cell
format dialog window. These include fonts, sizes, alignment options,
and borders. The orientation of the cell contents can be changed,
from the horizontal default to vertical, or something in between. The
AUTOFORMAT option under the FORMAT menu should also be explored, as
it provides a fast way to polish the visual appeal of a list with
pre-designed borders and font styles.
Step
4: Sort the List
Like a table created in Microsoft Word, data within an Excel
spreadsheet can be sorted in ascending or descending order by
different columns. To sort data in a spreadsheet:
- Select all the cells to be sorted by either shift-clicking
them or using a keyboard shortcut to select all cells (control-A
in Windows or command-A on a Macintosh).
- From the DATA menu, choose SORT.
- Select the columns to sort the data by, and choose either
asending or descending order.
- If a header row is present (usually the first row, containing
titles like Last Name, First Name, etc), make sure the 'header
row' radio button is selected at the bottom of the dialog
window.
- Click OK to sort the data.
The same student list can be sorted in different ways and
subsequently printed, generating lists from the same file for
different purposes. For example, the list can be sorted by last name,
locker number, birthday, or any other desired column. If parent
interviews are scheduled, the list can be sorted by the appointment
date column. If an interview date changes, the data can be resorted,
and a chronological list easily re-created with the updated
information.
Step 5: Add Calculation Fields
Even if a teacher is just using a spreadsheet to create and manage
a class list rather than create a complicated budget, calculation
fields can still be used with a minimum of expertise.
Spreadsheet calculations are performed by entering a FORMULA into
a cell, which performs a mathematical operation on data contained in
other cells and shows the result. All available functions within
Excel are accessible by choosing the INSERT menu and selecting
FUNCTION. Formulas in Excel begin with the equals sign, and are
followed by a combination of references to other cells (like A5 or
C9), mathematical operators, and functions.
For a class list, one of the most useful formula functions is the
COUNTIF function. This function counts the number of times a
particular string of text (a word or phrase) occurs in a spreadsheet
column or row. For example, COUNTIF can be used to count how many
times the word 'No' is displayed in the column titled 'Paid for class
field trip.'
To use the COUNTIF function:
- Select the cell the formula will be inserted into.
- Select INSERT - FUNCTION from the menu, and from the
STATISTICAL function category (on the left) choose COUNTIF (on the
right).
- Specify the range (the cells you want to count) by clicking
the small box with a red arrow on it next to the range field.
- The COUNTIF window will disappear. Click and drag to select
the cells you want to count.
- Press the ENTER key to make the range selection.
- Next to CRITERIA, type the equals sign followed by the text
string you want to search for.
- Click OK. The result of your formula using the COUNTIF
function should be displayed in your selected cell.
It is usually helpful to enter a label to the left of the cell
containing a formula, to clearly indicate what the number means.
Another basic function helpful on class lists is SUM. Access and
use it like COUNTIF, except the cell range is specified next to
NUMBER 1 in the dialog window. Use the SUM function to find the total
amount of student fundraiser money turned in, the number of absences
a student has, or any other group of fields containing numbers.
Mathematical functions like SUM and AVERAGE can be used to create
sophisticated spreadsheets used for tracking student attendance and
grades. While most classroom teachers will prefer to use commercial
gradebook or attendance software for these purposes, some school
districts have found an affordable alternative to these software
purchases in customized Excel spreadsheets designed by teachers. Some
are available for download from the internet, either as shareware or
freeware. An example is the 'Excel-lent Gradebook' by David Burger
(http://www.geocities.com/davidjburger/gradebook/.)
Four other examples are available on http://tracweb.ed.umuc.edu/gradebooks.htm.
Step 5: Hide Columns before Printing
A list within Excel may contain information not appropriate to
print or share with students or parents. In this case, entire columns
or rows of information can be temporarily HIDDEN from view for
display or printing.
For a parent conference, all rows except one student's can be
hidden so the parent just sees the grades for his/her child. For a
class list, student addresses and phone numbers can be hidden and
only name and permission form information displayed, if a list with
just those columns is needed for printing.
To hide rows or columns in Excel:
- Click or shift-click on the column headings (A, B, etc) or row
headings (1, 2, etc) you want to hide.
- From the FORMAT menu, choose either ROW or COLUMN (as
appropriate to your previous selection.)
- Choose HIDE.
Rows or columns you selected should now be hidden from view, but
they are still part of your spreadsheet. To reveal hidden columns or
rows:
- Shift-click to select cells in front of and behind the hidden
cells.
- From the FORMAT MENU, choose either ROW or COLUMN (as
appropriate).
- Choose UNHIDE.
STEP
6: Print with Options
When printing a page from Excel, note in the print dialog box
(that appears after selecting FILE - PRINT) several options are
available specific to Excel.
The entire workbook (the complete file) can be printed, only the
'active sheet' (the sheet selected from the tabs in the lower left
corner), or simply the cells selected by shift-clicking before
choosing FILE - PRINT.
These print options can further enable educators to limit the
information printed from an Excel file, and thereby customize it to
fit their needs.
Conclusions
Many computer users never learn to use true 'database software'
because of the list management features included in spreadsheets like
Excel, described in this article. 'Flat' data designs like those
possible in Excel are more limited in their advanced uses than actual
databases (created in Access or Filemaker Pro,) but can still serve
valuable functions. These can be basic like a class list, or complex
like a gradebook program offering a variety of assessment methods and
options.
Since the updated release of Microsoft Office for Macintosh in
1998, Microsoft Excel files have been fully 'cross-platform.' That
means the same Excel files created on a Windows computer can be
shared with a Macintosh user (provided both have Excel installed on
their computers), and vice versa. Macintosh users need only remember
to add the Windows file extension for Excel files (.xls), so Windows
computers will recognize and properly open the files within Excel. If
unusual fonts are used within the Excel document, they may appear
different on another computer if those same fonts are not installed,
but generally layout and appearance of Excel files should be the same
across platforms.
Once a list of student information or other data is created in
Excel, a TEMPLATE FILE can be created. This file, when opened, will
be formatted and already have some information entered. An example
might be a file in which student last names and first names are
entered, but other columns are blank and ready for data entry.
Whether the Excel file is used as a student list or a gradebook, use
of template files can be invaluable and save further time for
teachers. More information about templates and using them for both
administrative purposes and within instruction is available in the
article "Teaching with Templates" on http://www.wtvi.com/teks/99_00_articles/teachingwithtemplates.html.
Some educators, even those with considerable technology literacy,
are intimidated by the thought of using a spreadsheet. By attempting
the techniques described here with the assistance of an encouraging
and more experienced peer, hopefully such perceptions can be changed.
Technology integration can only become a reality when teachers are
not only provided with computer hardware and software, but also
frequent opportunities for training and mentoring from fellow
educators in methods like these.
