Seven Steps to Responsible Software Selection
In the early 1980s, relatively inexpensive
microcomputers came on the market, the personal
computer was selected Time magazine's "man (machine) of
the year," and school administrators rushed to buy early
generation Apple, TRS-80, Commodore, or similar
computers for their schools. Educational software was
limited, and what little there was consisted mostly of
"drill and practice" electronic worksheets. Teachers
often selected software from catalogs, choosing almost
any software that remotely touched on the subjects they
were teaching. Often they were disappointed when the
software arrived. Almost fifteen years later,
microcomputers in schools are no longer a novelty, but
contribute significantly in the learning process, and
software selection is taken as seriously as the
selection of text books. This Digest will outline a seven
step process for responsible software selection.
Step 1. Analyze Needs
The responsible teacher (or materials selection committee) should first
determine whether or not the computer is the appropriate medium to use to
satisfy particular instructional goals and objectives. There is always
the possibility that a careful needs analysis will result in a decision
to use some other teaching-learning strategy.
Needs & Goals. A need is the difference between "where we are now" (e.g. 60% of the students in the ninth grade score above minimum competence on the state science test) and "where we would like to be" (e.g. 90% of the students in ninth grade score above minimum competence on the state science test). "Where we would like to be" is another way of defining a goal.
Objectives. An objective describes "where we would like to be" in more specific terms (e.g. 90% of all ninth grade students will exceed the minimum level of competence on the state competency test administered in the second semester of ninth grade). Objectives must include conditions under which the desired behavior will be demonstrated and the criteria for measuring that behavior.
Educational objectives help us respond to needs by breaking them down
into attainable steps, making it easier to get from "where we are now" to
"where we would like to be." The educational objective stated above is a
"terminal" objective which must be broken down into a series of
"enabling" objectives (e.g. By October 31, 1995, all ninth grade students
will be able to correctly identify at least five out of seven minerals
when shown them by the teacher.) Enabling objectives identify
specifically what behavior we would like the student to demonstrate. For
each enabling objective, the teacher (or materials selection committee)
should brainstorm alternative learning methods for achieving that
objective_direct student teacher interaction, self-instruction workbook,
videotape, computer assisted instruction, etc.
After considering the benefits and constraints of each learning method,
the teacher (or materials selection committee) should be able to make an
informed decision about which medium or combination of media will satisfy
the identified needs, goals, and objectives.
Step 2. Specify Requirements
If a careful needs analysis determines that computer assisted instruction
is one of the methods that will be used to meet identified instructional
objectives, the teacher (or materials selection committee) should then
specify the requirements for the computer software. Factors to consider in
specifying requirements for software include: compatibility with
available hardware; cost (Will the school need multiple copies of the
software? Will a site license be necessary? ); user friendliness; level
of interaction desired; adequacy of documentation; access to technical
support via toll-free number; and of course, direct correlation with the
instructional objectives and curriculum requirements identified in the
needs analysis. Ellsworth and Hedley (1993) suggest that educators should
apply the following criteria within the context of their objectives and
the students' needs: content; instructional presentation; demands placed
on the learner; technical features; and documentation and management
features.
Step 3. Identify Promising Software
If requirements are specified in detail, the teacher (or materials
selection committee) will have a good head start when it comes to
identifying promising software. There are many ways to identify promising
software, and the responsible selector should use as many of them as
possible. Catalogs still remain an important source for descriptions of
software. Most district level educational communications/media centers are
on catalog mailing lists from virtually all software producers and
wholesalers. Software is advertised, described, and often reviewed in
magazines and journals found in school, university, and public libraries.
The Educational Products Information Exchange (EPIE) produces The
Educational Software Selector (TESS), a database containing descriptions
and reviews of thousands of currently published educational software
programs.
Teachers who have access to the Internet can find out about software from
other teachers by joining a listserv. Posting a question such as, "I am an
eighth grade science teacher and I am looking for interactive software for
a PC environment that will teach my students how to . . . " is likely to
bring dozens of responses. Many listservs are archived on the AskERIC
Virtual Library gopher (gopher
ericir.syr.edu) or WWW site (
http://ericir.syr.edu). Directions for joining a listserv may be
found in the archives, or e-mail
AskERIC@ericir.syr.edu for more information on listservs.
The above are but a few sources for identifying promising
software. The more precisely the requirements are specified in Step 2, the
easier it will be to screen out those products that are least likely to
meet the user's specifications and the easier it will be to focus on more
promising products.
Step 4. Read Relevant Reviews
After a list of promising software has been identified (using the
suggestions outlined in Step 3), the teacher (or materials selection
committee) may be able to narrow or expand the list by reading relevant
software reviews. It is very important to realize, however, that reading
reviews should not take the place of previewing, described in Step 5.
Software reviews may be found in educational journals, some of which may
be identified by searching the ERIC database using appropriate descriptors
(e.g. software, selection, evaluation, elementary, secondary). For
example, Heyboer and Mayo, in the January 1993 issue of Teacher Magazine,
describe 12 computer software programs available for elementary and
secondary math and science classes. Evaluation services such as EPIE,
subscribed to by many school and public libraries, provide a database of
selected software evaluations and reviews. A visit to the library is an
important part of responsible software selection. Keep Step 1 (Analyze
Needs) and Step 2 (Specify Requirements) in mind as you read the reviews.
It is also important to note the audience upon which the review is based.
A software program may have received a poor review because it was tested
with a different audience than the one you have in mind. Reviews are
important screening tools when used as part of the entire selection
process.
Step 5. Preview Software
The most effective way to judge whether software is appropriate or not is
to observe students as they interact with the program. Are the educational
objectives achieved when the student uses the program? The responsible
teacher should not purchase software without previewing it with his or her
own students. Preview as many programs as you can find that appear to
meet your selection criteria. Some software vendors will allow free
preview of an entire program. Some vendors will provide a free
demonstration disk containing a subset of a larger program. Some vendors
will not allow preview without a purchase order, but will allow the
teacher to return the program within a specified time limit with no
financial obligation. In some situations, a teacher may be able to borrow
a program from another teacher for preview purposes. As a general rule,
if there is no way to preview software with your own students--avoid that
software.
Step 6. Make Recommendations
After potential software has been previewed, it is time to make
recommendations for purchase. The responsible software selector should be
able to:
- select the most desirable software after a systematic evaluation of all alternatives in terms of educational objectives and constraints;
- establish a quantitative method for rating each alternative against the selection criteria established in Step 2;
- evaluate the relative importance of each selection criterion, (ie. previewing should probably be rated relatively high in importance); and
- create a written record outlining the reasons why a piece of software is recommended or not recommended for purchase.
For software that is recommended for purchase, teachers should include
suggestions for optimal use that might have become apparent during the
preview period. The written record, including the quantitative rating
scale and the selection criteria, should be kept on file for future
reference.
Step 7. Get Post-Use Feedback
After software is purchased and used with students, it is important for
the teacher to determine the conformance or discrepancy between all of the
enabling objectives specified in Step 1 and the student performance
actually obtained using the chosen computer software. The teacher should
keep records on the relative extent to which each objective is met or not
met. Objectives not met may be addressed by some other software program or
by another teaching/learning method. Post-use feedback can be a
significant help to a school's systematic process of software selection,
purchase and use. The accumulation of user feedback, including anecdotal
experience on the part of both teachers and students, will naturally serve
to improve future needs analyses (Step 1) and all succeeding steps in a
constantly improving software selection process.
