STANDARD GRADE COMPUTING STUDIES
Your computing course consists of three main areas of study:
Computer Applications
Computer Systems
Computer Programming
You are assessed on:
Knowledge and understanding(KU) of computer facts - assessed by external exam.
Problem solving(PS) using computers - assessed by external exam.
Practical assessment - assessed by tasks in school. Marks are then sent to SQA.
Computer Applications is broken down into the following units:
- General Purpose Packages (GPPs)
- Word Processing
- Spreadsheet
- Database
- Graphics
- Desktop Publishing
- Web Page Creation
- Expert Systems
- Communications and Networks
- Electronic Communication
- Local areaNetworks and Wide Area Networks
- Internet
- Industrial and Commercial Applications
- Automated Systems
- Commercial Data Processing
BEGINNERS GUIDE TO PROGRAMMING
Okay
This is the part of the Standard Grade course that most students don’t like. Generally this is due to the fact that it is the hardest part.
Think about it. It’s a new language. New keywords, commands, syntax errors. Solving problems using your own program. It takes time and concentration. You need to take the time to learn the language. You don’t learn French or Italian in 1 or 2 periods so why expect to learn a Programming language in that time.
We like instant results, we click and it happens. Were used to instant. Flick the switch its there. Programming is not like that. Programming can be very frustrating but at the same time rewarding. When you create your own code and solve the problem given you will feel heavy good.
So don’t give up. Help is at hand and remember, you will get there.
When given your problem or specification you have to develop your solution. You will be tempted to dive at the computer and try to write your program code. BUT there is more to it than that.
So without any more waffle lets get to it:
Software Development is the name given to:
· Analysing a problem
· Designing a solution using a computer
· Implementing the solution
· Testing the solution
· Documenting the solution
· Evaluating the solution
· Maintaining the solution
Programming is a problem solving activity. To be good at solving problems you have to be organised and METHODICAL. That is you must go about it in a set way, taking your time over planning and thinking. The more planning you do, the more time you’ll save yourself in the long run. Rushing headlong into
a problem and trying to just code into the computer without properly preparing everything usually means you take twice as long to solve a problem.
There ARE Seven stages in Software Development (see above), but we shall be mainly concerned here with four of them.
You are given a Specification, the problem you have to solve.
Then the steps you take involve:
ANALYSIS
A clear and brief explanation by the programmer (you) saying what the program will do and how it will do it. It’s a good idea to identify the inputs and outputs.
DESIGN
Breaking the problem down into steps, these steps can usually be broken down into smaller steps. This is called TOP DOWN DESIGN.
IMPLEMENTATION
You produce the program.
TESTING
Making sure it works correctly. Testing has to be planned and thorough. You don’t just run the program a few times to see if it works, you plan a table of inputs with expected outputs. You should use normal inputs, extreme inputs to test your program fully.
Hints and Tips for examinations and tests
- Take your time and read the question carefully. Make sure you understand what it is you are being asked about.
- Dont panic if you dont know the answer straight away.
- Look at the number of marks available. For instance, if three marks are available, then you should make three different points in your answer, one for each mark.
- Answers such as "easier" or "faster" will not be awarded any marks unless you give a reason to justify them, for instance "It is faster to load a program from disk than from tape because...."
- As a rough guide, you should write at least one sentence for each mark.
- Give as full an explanation as you can within the time available.
- It doesnt harm your marks to include extra information in your answer if you have the time.
- Never leave questions unanswered unless you run out of time. Blank spaces always get no marks.
- Draw a diagram if it will help to clarify your answer.
Resist the temptation to leave the examination early just because you see others going out. Try to relax and look over your answers again, to make sure that you have attempted all of the questions.
