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 - Kiribati (DS4OERS) micro-course. Please consult the Certify participation page for more information.
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
- 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
