Research venue- should be a research journal- you can look at journals in higher education and psychology.
Value proposition should be written in relation to a singular or multiple stakeholders- how is your proposed project of particular value in helping the stakeholder address the learning "mistake" you've identified?
Overall, I love this project idea! However, I think the canvas needs to be reframed to focus on a specific learning issue rather than outcomes. What specific learning issue is occurring that impedes "underprepared" undergraduate students from graduating? Right now this is framed in terms of policy and psychology.

Research question - you have a 'better' statement, so i feel like you need to add the second part - "would better support...THAN.."
I feel like the mistakes aren't learner mistakes, but external to the learning; i think you can provide more detail here to really articulate what the mistake is, it feels a little broad to me (maybe they're underprepared because they haven't taken advantage of resources available to them? for example)
