Understanding Useability principle: ease of learning in QCE Digital Solutions Unit 3

What it does: The label 'Submit order' states the action plainly, which makes the control easy to learn. The magnifying glass is a widely recognised convention, so users learn the control without training. A familiar icon plus a clear label lets a new user work out the task without training. Ease of learning is a useability principle about new users, not about system speed. Familiar conventions use symbols and positions that users have already seen in other apps. A clear label says exactly what will happen, so users do not have to guess. Onboarding hints guide new users inside the interface at the moment they need help, so no training is needed.

Common mistakes: The button's closing tag is missing its slash. It should be <button>Sign up</button>. The clear label 'Sign up' tells a new user what the button does. The option is called text, not txt, so the label would not show. It should be tk.Label(text="Email").pack(). A visible label tells a new user what to type.

Match the Pairs

Button label: "Save" with a floppy-disk icon → Uses a familiar convention so a new user recognises what the button does without being taught
Tooltip: "Tap + to add your first task" → An onboarding hint that guides a first-time user through their first action
Clear labels tell a new user exactly what a control does, so they can learn the interface quickly → <button>Submit order</button>
Familiar conventions, such as a magnifying glass for search, let new users guess how to use the interface → <button aria-label="Search">🔍</button>
<button>Go</button> → The label 'Go' is vague, so a new user cannot tell what will happen. A clear label like 'Book appointment' would be easier to learn.
Home screen shows 12 unlabelled icons and no hints for first-time users → There are no clear labels or onboarding hints, so a new user cannot work out how to start. Add labels and a short first-use guide.

Hint: Type the attribute that links this clear label to the input with the matching id.
2. <input id="email" placeholder ="name@school.edu.au">
Hint: Type the attribute that shows faint example text inside an empty field to guide a new user.
3. <input type="password" id="pw">
Hint: Type the familiar input type that hides typed characters, which users expect on login screens.
4. <button title="Save your work">Save</button>
Hint: Type the attribute that gives a tooltip hint when the user hovers over the button.

Spot the Error

Question 1
A <form>
B <label for="em">Email</label>
C <input id="em" type="email">
D <button>Sign up<button>
E </form>
Line D — The button's closing tag is missing its slash. It should be <button>Sign up</button>. The clear label 'Sign up' tells a new user what the button does.
Question 2
A root = tk.Tk()
B tk.Label(txt="Email").pack()
C box = tk.Entry(root)
D box.pack()
Line B — The option is called text, not txt, so the label would not show. It should be tk.Label(text="Email").pack(). A visible label tells a new user what to type.
Question 3
A <label>Password</label>
B <input type="password">
C <small>Use 8+ letters<small>
Line C — The closing tag needs a slash: </small>. Without it the hint breaks the page. A short hint under a field is an onboarding hint that helps a new user.
Question 4
A <h1>Authenticate session</h1>
B <label>Username</label>
C <input name="u">
D <button>Log in</button>
Line A — 'Authenticate session' is technical jargon a new user may not understand. It should use the familiar, clear wording <h1>Log in</h1>, which also matches the button.
Question 5
A if first_visit:
B show_tip("Tap + to add")
C first_visit == False
Line C — == compares the values and changes nothing, so the tip would show on every visit. It should use = to assign: first_visit = False. Onboarding hints should appear only to new users.
