The 20 questions

  1. What is the most important check when judging whether an online source is trustworthy?

    • How colourful and attractive the page looks when it is first opened on the screen
    • Who created it, why, and whether the information can be checked against other reliable sources
    • How long the page takes to load on a device with a fast internet connection at home
    • How many times it has been shared on social media by people the user already knows

  2. A website has no author, no date and no sources. What should a pupil do?

    • Treat its claims with caution and check them against reliable sources before using them
    • Ignore every other source in favour of this site, because it is the most recent one
    • Trust the site because it has a professional design and loads quickly on a laptop
    • Copy the information straight into the project, because the website must be correct

  3. What is bias in an online source?

    • A delay in loading a video that makes the page look slow to the user
    • A small typing error that changes one number in a table of data on the page
    • A choice of font that makes the text harder to read on a small screen
    • A slant that favours one view or interest, which may leave out other sides of the story

  4. Why should a pupil compare information from more than one source?

    • To ensure that the information matches the first source exactly in every word used
    • To check that facts agree and to spot errors or one-sided claims
    • To avoid having to write the project in their own words, since copying is quicker
    • To make the project longer, because a single source is never enough to write anything

  5. What does it mean for a design to be consistent?

    • Similar elements, such as headings and buttons, look and behave the same way across the product
    • Every page uses a different colour scheme so that no two pages look the same to the user
    • All text is written in capital letters, so that the user can read it more easily on screen
    • Each page contains the same number of images, whatever the content of the page is about

  6. Why is good contrast important in a design?

    • It makes the page load faster, because high contrast images are always smaller in size
    • It makes the design more expensive to produce, so the product appears more valuable to buyers
    • It makes text and key items easier to read, especially for people with low vision
    • It makes the text impossible to copy, which protects the content from being reused

  7. Which feature most improves the usability of a navigation menu?

    • Many menu items with small icons only, so that the menu takes up less of the screen
    • Hidden menus that appear only after several clicks, to keep the page looking simple
    • Menu items that change their names each time the page is opened by the user
    • Clear labels and a logical order, so the user can find each section quickly

  8. What is alt text used for on a web page?

    • It describes an image for people using screen readers or when the image does not load
    • It stores the image in a compressed form so that the page takes less time to download
    • It changes the colour of the image so that the page is easier to view on a dark screen
    • It shows a hidden message that appears only when a user presses a key on the keyboard

  9. A design uses small, pale text on a light background. What problem is most likely?

    • The text may be hard to read, especially for users with visual impairments
    • The page will be more secure, because pale text cannot be copied by other users
    • The page will be more trustworthy, because pale text shows that the author is careful
    • The page will load more slowly, because pale text always takes longer to download

  10. Which statement about usability is correct?

    • A usable product is always the most expensive version available on the market today
    • A usable product has the largest number of features, whatever the user actually needs
    • A usable product lets people reach their goals efficiently, effectively and with satisfaction
    • A usable product does not need to be tested, because usability is decided by the designer

  11. Why should a designer keep the number of steps needed to complete a task small?

    • Fewer steps remove the need for instructions, so the product never needs any help text
    • Fewer steps make the task quicker and reduce the chance of users giving up
    • Fewer steps mean the product needs less testing, because there is less to go wrong
    • Fewer steps make the product more expensive, which increases the value for the user

  12. What makes a source trustworthy when it contains statistics?

    • The statistics are shared by a large number of people on social media in one day
    • The statistics are presented in a large font and a bright colour that makes them memorable
    • The statistics are printed on a page with a photograph of a person in a lab coat
    • The data is from a reliable source, the method is explained, and the figures can be checked

  13. A pupil finds a 'news' article that matches their own opinion exactly. What should they do?

    • Use it as the only source in the project, because it saves time to rely on one article
    • Check the article against other reliable sources, because agreeing with it is not proof that it is true
    • Share it at once, because a story that matches their view is more likely to be correct
    • Ignore all other sources, because they are likely to disagree with the pupil's own view

  14. What does a 'call to action' do in a well-designed interface?

    • It asks the user to rate the product on a scale of one to ten in a pop-up window
    • It changes the colour of the background at random so the user is kept interested
    • It plays a sound effect every time the user moves the pointer around the screen
    • It tells the user clearly what to do next, such as a button that says 'Save'

  15. What is the purpose of a user interface being responsive?

    • It adapts the layout to different screen sizes so the content stays easy to use
    • It makes the device run faster by reducing the number of programs that are open
    • It makes the page impossible to resize, so that the layout stays fixed for the designer
    • It sends the user's data to a different server so that the page loads more quickly

  16. Why is it important to test a design on a range of devices?

    • Testing on several devices is only needed for games, not for educational or business content
    • Testing on several devices is expensive, so it is best to avoid it for all projects
    • Different screen sizes and input methods can reveal problems that do not appear on one device
    • A design that works on one device will always work on all others without any change

  17. Which of these shows a trustworthy design choice for an online form?

    • Hiding the purpose of the form, so that users do not question why information is needed
    • Explaining why each piece of personal information is needed before asking for it
    • Asking for as much personal information as possible at the start, to keep records complete
    • Making the submit button look like an advertisement, so users click it without reading

  18. Which of these is a sign that a website may be a scam?

    • It asks for bank details to claim a prize that the user never entered
    • It explains clearly how to unsubscribe from any emails it sends to the user
    • It uses a secure address starting with https and shows a clear privacy policy
    • It lists a named contact and a postal address for the organisation running it

  19. Why should a designer use familiar icons together with text labels?

    • So users understand what each control does without having to guess its meaning
    • So the text can be hidden from view, which makes the page look simpler and cleaner
    • So the page can load without any images, which reduces the amount of data it needs
    • So the icons can be made larger, which makes the page look more impressive to visitors

  20. What is the purpose of a helpful error message in a design?

    • To stop the user from using the product until a manager has been contacted
    • To show a random message so that the user is kept interested in the product
    • To hide the problem from the user so that the design appears to be working well
    • To tell the user what went wrong and how to fix it
