Teacher Guidance

Standard Procedures (Task B and C)

What is a standard procedure?

A standard procedure is a series of step-by-step instructions that explain how to do an activity.

How should they be written?

SOPs should be written in a concise, step-by-step, easy-to-read format.

The information presented should be unambiguous and not overly complicated.

The active voice and present verb tense should be used. The term "you" should not be used, but implied.

The document should not be wordy or overly lengthy. Keep it simple and short.

What do we expect to see?

A series of steps which should be numbered and written in an appropriate order. Candidates should use appropriate technical language.

The standard procedure should be written as instructions without the word ‘you’. If the phrase ‘you will’ or ‘I will’ is consistently used this should mean that they will not normally score beyond level 1 for the communicating aspect of ‘devising methods’.

Some sensible reference to how the step is done safely should be included where relevant (e.g. fill the burette at eye level, wear gloves to …).

Please note that a risk assessment is not required in either task B or C.

Please see secure website/CPD materials for exemplars.

The following can be adapted for use with your learners.

Writing Standard Procedures (Standard Operating Procedures)

If we want to follow a method to successful results then the method needs to be clearly written so that the worker knows exactly what to do. A recipe is a list of instructions that should tell us how to cook successfully. Look at the three recipes below and put them in order of easiest to follow. Put 1 for easiest and 3 for hardest to follow. Now go through each recipe and say what is good or bad about the way it is written.

Method 1 Method 2 Method 3

Firstly, you will heat the oven to 160C/gas 4. Next you will grease a 20cm cake tin and then line the bottom with a circle of greaseproof paper.

Secondly you will need to beat the butter and sugar together, and then add the eggs, one at a time, mixing well after each addition. After that you will fold through the flour, milk and vanilla extract until the mixture is smooth.

Thirdly you need to divide the mixture between 2 bowls and stir the cocoa powder into the mixture in one of the bowls. After this take 2 spoons and use them to dollop the chocolate and vanilla cake mixes into the tin alternately.

Fourthly, You will need to bake the cake for 45-55 mins until a skewer inserted into the centre comes out clean. Finally you will need to turn out onto a cooling rack and leave to cool.

Standard Procedures (Standard Operating Procedures)

What is a standard (operating) procedure?

A standard (operating) procedure is a series of step-by-step instructions that explain how to do an activity.

A recipe is a good example of a standard procedure.

Notice that the recipe

–method 2- on the previous page did not contain the word ‘I’ or ‘you’.

What was written was a simple list of instructions to follow.

STANDARD

OPERATING

PROCEDURE

A good recipe tells you exactly what to do. e.g. It does not just tell you to switch an oven on but to what temperature it should be set.

The better procedure

Look at the two similar procedures below which have been written to test the strength of different threads. One standard procedure is better than the other.

Use a highlight pen to show the differences between the methods.

Now explain which method you would find easiest to follow.

Method A Method B

1. Set the apparatus up as shown in the diagram.

Safety: Make sure that the apparatus is not set up near the edge of the table.

1. Set the apparatus up as shown in the diagram.

Safety: Make sure that the apparatus is not set up near the edge of the table.

2. Attach one end of a thread to a clamp and the other to a mass hanger as shown in the diagram above.

3. Clamp a ruler, as shown in the diagram, so that it is possible to measure the bottom of the mass hanger.

4. Measure the length of the thread without any mass attached. Note this in a table.

2. Attach one end of a 20 cm length of thread to a clamp and the other to a mass hanger as shown in the diagram above.

3. Clamp a ruler, as shown in the diagram, so that it is possible to measure the bottom of the mass hanger.

5. Add a mass to the hanger and record the reading of the thread from the ruler into the table. Calculate the extension of the thread by subtracting the original length from the new one.

6. Continue to add masses to the hanger recording the new length and extension of the thread each time. This should be repeated until some readings are taken.

If the thread breaks after adding a few more masses, then steps 1-6 should be repeated using lighter masses instead.

4. Measure the length of the thread without any mass attached. Note this in a table.

5. Add a 100g mass to the hanger and record the reading of the thread from the ruler into the table. Calculate the extension of the thread by subtracting the original length from the new one.

6. Continue to add 100 g masses to the hanger recording the new length and extension of the thread each time. This should be repeated until 8-10 readings are taken.

If the thread breaks after adding a few 100 g masses, then steps 1-6 should be repeated using 50 g masses instead.

Putting a standard procedure in the right style

Making a cup of coffee

Look at the following method to make a cup of coffee.

First you will take a mug from the cupboard and then next put in one teaspoon of coffee. After you have done this you will need to add boiling water from the kettle until the water level is about 1 cm from the top. Lastly add some milk.

First turn this method into a list of numbered steps. Don’t worry about the use of the word ‘you’. You do not need to change the English at this stage. Just put the method into a series of numbered steps.

Writing a standard (operating) procedure

Before you write a standard operating procedure, can you remember what a standard operating procedure is?

Some rules for writing a standard (operating) procedure

Standard procedures should be:

written as a series of steps;

easy-to-read;

to the point.

The information presented should be clear and not overly complicated.

The active voice and present verb tense should be used. The term "you" should not be used, but implied.

Some sensible reference to how the step is done safely should be included, where relevant .

Lighting a Bunsen burner

Now that you have the idea for writing a standard procedure, try to write a standard procedure for lighting a Bunsen burner.
