Selecting a tool for an audience and purpose

Choosing a tool because its features match what the content must do and who will use it, then justifying the choice with reasons like ease of use, device support and cost.

Understanding Selecting a tool for an audience and purpose in Years 9–10 Data & Information

What it does: A fair comparison lists the same criteria (cost, ease of use, device support) for both tools so the better fit is clear. Start with purpose and audience. Then you can match tool features to those needs. Device support is a valid reason that links the tool to the audience. A friend's preference is not. A feature is something the tool can do. A favourite is a personal opinion.

Common mistakes: An IF statement needs THEN after its condition. The line should be IF toolA matches needs THEN, so the program only picks toolA when its features match the needs. Text values must be inside quotation marks. The line should be audience ← "Year 7 students" so the audience is stored as text.

Match the Pairs

fit for purpose → A tool whose features match what the content must do and who will use it
Features: video, quiz, works on phones → A list of what a tool can do, used to compare it against what the content needs
Comparing two tools by checking the same criteria for each one → Tool A: free, easy, phone and PC | Tool B: $15/month, hard to learn, PC only
Justifying a choice with reasons linked to the audience and purpose → I chose Tool A because it is free, easy for Year 7 students and works on their phones.
I chose Tool B because it is the most popular app. → The reason is about popularity, not about whether the tool's features suit the content or the audience.
Tool A: free, easy | Tool B: PC only, $15/month, hard (no features listed for the task) → The comparison is unfair because it does not check the same criteria, including device support, for both tools.

Hint: Type the assignment symbol that stores the list of tool features in a variable.
2. IF "phone" IN features THEN deviceOk ← TRUE ENDIF
Hint: Type the keyword that checks whether an item is inside a list.
3. costA ← 0 costB ← 12 IF costA < costB THEN pick ← "Tool A"
Hint: Type the comparison operator that checks Tool A costs less than Tool B.
4. pick ← "Tool A" reason ← "free and easy to use" OUTPUT pick + " because " + reason
Hint: Type the variable that holds the justification for the choice.
5. IF deviceOk AND costOk THEN fitForPurpose ← TRUE ENDIF
Hint: Type the logical operator that needs both conditions to be true.

Spot the Error

Question 1
A purpose ← "phone quiz"
B needs ← ["touch", "free"]
C toolA ← ["touch", "free"]
D IF toolA matches needs
E choice ← toolA
Line D — An IF statement needs THEN after its condition. The line should be IF toolA matches needs THEN, so the program only picks toolA when its features match the needs.
Question 2
A audience ← Year 7 students
B device ← "school tablets"
C tool ← "TouchQuiz"
D SHOW "Chosen: " + tool
Line A — Text values must be inside quotation marks. The line should be audience ← "Year 7 students" so the audience is stored as text.
Question 3
A toolA ← ["free", "offline"]
B FOR EACH f toolA DO
C SHOW f
D END FOR
Line B — A FOR EACH loop needs the word IN between the loop variable and the list. It should be FOR EACH f IN toolA DO so each feature in the list is shown.
Question 4
A scoreA ← 0
B toolA.free ← true
C IF toolA.free ← true THEN
D scoreA ← scoreA + 1
Line C — ← assigns a value, but an IF needs a comparison. It should be IF toolA.free = true THEN so toolA scores a point only if it is free.
Question 5
A choice ← "TouchQuiz"
B reason ← "works on phones, free"
C SHOW choice + " because " reason
Line C — There is a missing + before reason. It should be SHOW choice + " because " + reason so the choice and its justification join into one sentence.
