M/A/R checkpoints
Guided problems break a worked solution into ordered steps. Each step can award method, answer, or reasoning marks.
the three marks
| mark | name | awarded for |
|---|---|---|
| M | Method | Using the correct technique or approach. |
| A | Answer | Getting the correct value at the step. |
| R | Reasoning | Providing valid justification for a non-obvious step. |
step dependencies
Each step has its own prompt, response, grading strategy, mark type, and mark count. OptionaldependsOn and allowFollowThrough fields describe how a later step can build on earlier work.
