Welcome to the Final Step: Reviewing and Evaluating Outcomes
Imagine you have just spent hours building a high-tech Lego set. Before you show it off, you check it against the picture on the box. Does it look right? Does the steering wheel actually turn? Could you have used a better tool than your fingernails to pry the pieces apart? In the world of ICT, this process is called Reviewing and Evaluating.
This chapter is part of Topic 5: Applying Information and Communication Technology. It is a crucial part of your Paper 2 (Practical Paper). While other chapters focus on making things, this one focuses on thinking about what you made. It covers Assessment Objective 3 (AO3), which is all about analysis and evaluation.
1. Comparing the Product with the Requirements
Before you start any ICT task, there are original requirements (often called a 'brief' or 'client needs'). These are the rules you were told to follow, such as "The poster must be portrait" or "The database must show only the names of students in Year 11."
The first step of evaluation is to look at your finished work and ask: "Did I actually do what was asked?"
Fitness for Purpose: This is a key ICT term. If your digital product meets all the requirements and does its job correctly, it is fit for purpose. For example, if you created a spreadsheet to calculate a budget and the formulas work correctly, it is fit for purpose.
Quick Checklist for Requirements:
- Did I include all the required data?
- Is the layout what the client asked for?
- Does the solution actually solve the problem?
2. Identifying Strengths and Weaknesses
To get top marks in your evaluation, you need to be honest. No digital product is ever perfect! You must be able to analyse your work to see what went well and what didn't.
Strengths: These are the parts of your work that you are proud of or that work particularly well.
Example: "The house style is consistent because I used the same font and colors on every page of the website."
Weaknesses: These are areas that might be confusing for a user or look slightly messy.
Example: "The image on the flyer is slightly blurry (pixelated) because I stretched it too much."
Memory Aid: The "SW" Approach
Whenever you finish a task, think SW: Strength (What is great?) and Weakness (What is "meh"?). This makes it much easier to write your evaluation notes during the exam.
3. Suggesting and Making Improvements
Once you have found a weakness, you need to suggest an improvement. This shows you have a reasoned judgement (another important exam term!).
Don't worry if you don't have time to fix everything in a practical exam. The examiner wants to see that you know how to make it better.
Common Improvements Include:
- Formatting: "I could use bold headings to make the information easier to find."
- Accuracy: "I should proofread the text again to find any spelling mistakes."
- Layout: "I could use more white space so the page doesn't look so crowded."
- Functionality: "I could add a drop-down menu to the database form to make data entry faster."
4. Evaluating the ICT Tools Used
This part is about the "How." You need to explain why you chose specific software features and if they were effective.
Think about the software facilities you used (like VLOOKUP in a spreadsheet or Mail Merge in a word processor). Were they the best choice?
Example of Tool Evaluation:
"I used a Database instead of a Spreadsheet because I needed to create relationships between two different tables of data. This was effective because it reduced data redundancy (repeating data)."
Did You Know?
In the Pearson Edexcel IGCSE, AO3 (Analysis and Evaluation) makes up about \(24\text{--}26\%\) of your total grade! Developing these "reviewing skills" is just as important as knowing how to use the software.
5. How to Write a Great Evaluation
When you are asked to evaluate your outcome in the exam, try to follow this three-step structure for your sentences:
1. State the fact: "I used a sans-serif font for the body text."
2. Explain the effect: "This makes the text look modern and easier to read on a screen."
3. Make a judgement: "Therefore, it is suitable for the target audience of teenagers."
Common Mistakes to Avoid:
- Being too vague: Avoid saying "It looks good." Instead, say "The alignment of the images makes the page look professional."
- Forgetting the audience: Always remember who the product is for. A presentation for a bank manager should look different from a poster for a primary school disco!
- Ignoring the "Original Requirements": If the brief asked for a logo in the top right, and you put it in the bottom left, mention it as a weakness!
Key Takeaway Summary
- Reviewing means comparing your work to the original requirements.
- Evaluation involves identifying strengths (what works) and weaknesses (what doesn't).
- Fitness for purpose means the product does exactly what it was designed to do.
- Improvements should be specific and focus on making the product better for the audience.
- You must be able to justify why the ICT tools you chose were the right ones for the job.
