SURVEY, for Windows 3.x and above, is
available from SPA
When I first received my copy of this package and saw the SPA
label I held a great deal of optimism as I have always enjoyed using their well
thought out school material. I was not to be disappointed. Survey needs Windows
3.1 or later to run and installed very easily on Windows 95. The package runs
as three separate programs, Survey Designer, Survey User and Scatter which need
to be accessed seperately from their icons and would demand some knowledge of
working in a Windows environment from pupils. Once inside the programs the
large clear and simple toolbar is very friendly and would be a good
introduction for pupils not familiar working in this computer environment. In
each program however there are discrete menus which a teacher, or more advanced
pupil, could use to fine tune the program.. The first program, 'Survey
Designer', is what it says, a means to set up a sheet on which data could be
collected. Whether this would satisfy the National Curriculum requirement on
designing a collection sheet is doubtful as the only big decision is whether to
use words, single numbers or groups in the left hand columns. The number format
option allows discrete numbers or groups to be used. The groups can described
in different ways; "0-9" or "0 and less than 9" but sadly there is no option to
use inequality notation which is restricting for more advanced pupils (Note:
in fact you can; Survey Designer allows you to use any text in describing
grouped data; you simply type the separated text you want in the "Text" box in
the number format option, so you can have "10 to 19" or "10 - 19" or "10 and
<=19" or "10<=L<=19" or whatever, Ed). There are options to assign
particular colours or icons from a library given or pasted in from other
programs (although the latter is not that easy to scale correctly), and these
are used later on to draw charts. This is something I am sure will appeal to
pupils. The recording sheet can be printed at this stage so that pupils can go
around and collect their own data, though some Network Managers might want to
curb the multiple copies option. In The 'Survey User' option the data
is easily entered by clicking in the tally column to create bar & gate
tallies. As well as those created in 'Survey User' there are a bank of useful
recording sheets for data such as pupil's heights. If not enough space is
allowed the program starts to use (10)'s to fit all the tallies in which was
slightly messy. The real meat of this program is however in producing suitable
charts. Like many who have watched pupils produce very pretty but totally
useless graphs with spreadsheet packages, I was keen to see how technically
sound the graphs in this section were. When using groups 0-9, 10-19 etc. the
bar chart leaves gaps and this worried me, but once the group descriptors are
changed to 0.0-9.9 etc the gaps disappear. This I think would make a very
useful teaching point about drawing such charts and the need for different
graphs in different situations. Again the program is sensible in its choice of
charts for qualitative and discrete data, and frequency polygons are plotted
against mid-marks. Although some 'silly' charts are possible with continuous
data (e.g. 'stick' diagrams plotted against mid marks) the program is generally
thoughtful in the use of bar charts. The pie charts have a minor problem in
overwriting of labels when sectors are small but the use of a colour scheme
chosen in Designer would give students the feeling that they had ultimate
control over the appearance of these charts. The printout is disappointing -
charts that looked attractive and large on the screen are small and
undistinguished as hard copies. I think pupils looking for charts to go in
projects would feel let down by these. (Note: users have control over the
printed size of their chart by simply changing the size of the chart window,
Ed.) The 'averages' which are produced are sound, in particular with
grouped data the 'modal-class' is given rather than attempting to calculate a
precise value. What would be nice from a teaching point of view, and to
encourage good practice in report writing, is some attempt to show the working
in calculating these values. The last program 'Survey Scatter' is a bit of
an anomoly in that it functions completely seperately from the other programs
in the suite. Two variables can be entered in columns against individuals names
and this can easil;y be extended to more variables. It has a useful tool
whereby the teacher can set sensible ranges for values in each column so that
pupils cannot enter clearly incorrect values. The scatter diagrams it produces
use sensible scales with an option to include (0,0) on any graph. This avoids
the problem on so many packages where some manipulation of scales is needed to
give a useful graph. There are I think two major weaknesses with this
program:-
- It is not possible to carry out any operations on individual
columns as a spreadsheet might do. This program cannot calculate, for example,
the mean of a particular variable and the data would have to be re-entered in
Survey Designer/User to do this. This singling out of bivariate data as
separate from single variable work is clumsy and unhealthy from a teaching
point of view.
- There is a 'Statistics' option which give the correlation
coefficient and an equation of a line of 'best fit', which it is then possible
to draw on the graph. The calculations are way beyond the scope of the pupils
it is clearly aimed at and one must view with some horror the production of
these figures, as it were, from thin air. This program I felt was almost an
afterthought, it didn't tie up with the rest of the suite both from the
transfer of data aspect and from the teaching outlook.
Overall I felt that this was a very useful package. Its
design suggests it to be a research tool for younger pupils for which purpose
it would serve very well. The ease of use, yet the way it mimics more
sophisticated programs, make it a good package to use with children at KS2 and
KS3 and G course students throughout. Pupils who were familiar with
spreadsheets such as EXCEL would however find it
rather trivial. The statistics is largely sound, and many aspects of it give
this package potential as a teaching tool if suitable material is written
around it. In particular the diagrams were largely well thought out and avoided
many of the bad practices which some spreadsheets encourage. |
