Hey Kate,
Constructivism is an effective way to actively learn about new things. This is especially important in digital spaces, because, as you mentioned, it is easy to feel passive. I agree that learning activities that make you interact with the subject forces you to think creatively about the topic, not just within the classroom, but also in the real world.
You mentioned your goal of becoming an elementary teacher. So, I imagine you have an interesting perspective when it comes to learning theories. It’s interesting how you mention the use of digital tools in second grade. Which shows how common digital tools are in modern-day classrooms. And how learning theories, such as constructivism, in digital spaces is important to contextualize when familiarizing with our modern-day education.
