DS4OERS/Repository/diagram remix/Quiz

The questions which follow provide a basic knowledge test of selected concepts covered in this learning pathway: Vector chart or diagram remix.

The questions published at the end of each learning pathway are re-used for the knowledge test for learners interested in earning a digital badge or certificate of participation for the Digital skills for OER sharing (DS4OERS) micro-course. Please consult the Certify participation page for more information.

True - false questions

Indicate whether the following statements are true or false:

• The industry standard resolution for printed images is 300 DPI (dots per inch)
  • True

  • False
    • Incorrect. 300 DPI produces a good quality of printed image.
• Vector graphics are suitable for diagrams and graphs
  • True
    • Correct.
  • False
    • Incorrect. Vector graphics are images based on computer-generated shapes and colours, so are well-suited to diagrams and graphs.
• PDF is the best file format for sharing OER (open educational resources)
  • True
    • Incorrect. Because PDFs are not easy to edit, they do not make it easy to adapt images or text for re-use - a core feature of OER.
  • False
    • Correct. Because PDFs are not easy to edit, they do not make it easy to adapt images or text for re-use - a core feature of OER.
• You are free to re-use any svg file on the internet
  • True
