So how does a teacher not get caught in the lie?
1 - Adults and children naturally use a combination of online and offline learning
I don't know of anyone, and I'm sure you do too, that learns everything online. YouTube is great, so is Wikipedia and a ton of other sites. But, I don't read my tractor manual online. I go the paper manual and read it because it's easier. I don't read professional reading online because I like to annotate the text as I read. I didn't learn how golf online. I went out and got myself a golf coach.
What I do, and I'm pretty sure you do too if you're reading this, is to go online and learn when it makes the most sense and learn offline when it makes the most sense. It's natural to choose the best way of learning something and both adults and school-age children do this.
2 - Paper will continue to be used
Hate to say it but paper/pen/pencil isn't going away. The value of writing, annotating, drawing, and put ideas on paper is essential. I've tried to take notes online and I always forget what notes I took. However, I'm more apt to go and read notes I've taken on paper. Why? I believe it has to do with the physiological response of moving a pen and thinking deeply about what to write or draw which forces a deeper memory response. In other words, I remember stuff better when I write it because I wrote it.
Paper/pen/pencil/markers and the like will continue to be valuable, so make a balance in your classroom between tech and non-tech learning.
3 - It's better to give students descriptive effective feedback on a paper
Sure, it's possible to give feedback to students using tools like Kaizena, Goobric, Seesaw and other online assessment tools. Many teachers have found these tools to be effective. What I've found through many conversations with teachers is it's more difficult to make comments on Google Docs and such because it takes longer and it's more difficult to give descriptive feedback.
I believe that the personal touch - written comments and feedback - is what students need to truly understand what they know and what they need to improve.
Moving to completely to online learning is a lie. Teachers need to create a balance between online and in-person work.
Am I way off base or truth-telling? Let me know.
