Task 10 - Data Capture/Entry Forms
Before information can be processed it is necessary to collate, collect or capture it. There are a number of ways that this can be done.
One of the most common methods of data collection is through a data capture form. You probably use these on a regular basis on the Internet. You might have already created one if you made a database for your GCSE project or maybe you have created a questionnaire for another subject.
The information on paper data capture forms is usually entered into the computer manually by someone typing in the results or sometimes automatically using an input device such as Optical Character Recognition [OCR] (e.g. National Lottery, multiple choice exam papers).
Electronic data capture forms such as the one above speed up the process as data can be instantly transferred to the electronic database. Processing of the data can take place as soon as the data is entered. For example you might have received an instant confirmation email when signing up to services online.
Below is an example of a questionnaire I have started to design to find out what effects people think computer games have on students. I think video games are a good thing and will become a much bigger part of education in the future, not many people agree with me!
It still needs some work which you are going to do for me (click on it to make it bigger). You might think I could have incorporated some extra spreadsheet features such as drop-down boxes. You might think I should have allowed some extra space for responses. You might think I should have used entirely different software to create my questionnaire... Recreate my data capture form using your own design. Add the following questions with suitable data capture facilities:
5. Have you played any video games that you feel are educational? If so what and why?
6. On average how many hours a week do you spend playing video games?
7. On average how much money do you spend a month on computer games?
8. How do you feel ICT will change education in the future?
When you have finished your form, post a picture of it to your blog. Do a really good job and I might buy copyright of the finished questionnaire from you to use in my own studies!
