Two rounds into summative oral assessments now, and something’s changed: fewer of my students are telling me “I didn’t prepare.” A few weeks ago, that was the most common answer. This week, it’s becoming the exception.
This one’s a solo update — no guest, just what’s actually happening in my classroom, plus a piece of news I’m genuinely excited about.
On the vivas side: students are showing up rehearsed, some of them using an AI practice tool to run through questions ahead of time. And a pro-tip. Asking a kid to diagram something live, on the spot, tells me more about what they actually understand than almost anything else I do.
And on the other side of the equator: ten years ago, I helped run one of the first large-scale flipped-classroom pilots in Misiones, Argentina. That relationship never really ended — and this month, the first unit of a fully Spanish-language, Argentina-contextualized Mastery Flip course went live. If you’re Spanish-speaking, or know someone who is, I’d love for you to check it out.
