About TeachFX

Our vision: to use machine learning to provide teachers with a wide range of valuable metrics about your teaching practice and classroom dynamics:

Who is doing the talking in your classroom? How much lecture is happening, versus how much discussion or group work? Are students engaging in discussion with each other? Is the teaching providing more positive or negative feedback – and to which students?

Listen to the TeachFX theme song by the amazing Matt Farley:

Here are some examples of the types of reports that TeachFX will provide to teachers in the future:


How teachers can use this: “Wow, Elena is normally such a good participator that I hardly noticed that she didn’t speak at all this week. I wonder if things are okay at home? I’ll check in with her tomorrow.”

“Hey, it looks like Lorenzo participates a lot in your class but doesn’t participate much in mine. What are you doing to bring him out of his shell? I’d like to give tips to his other teachers.”

“Note to self: be sure to call on Brian and Demario today.”


How teachers can use this: “This is great: my principal and I set a target for more discussion in my class, and I’m really making moves in the right direction!”

“I need to work on getting students talking to each other… Tomorrow I’m going to try holding a little longer after each student’s comment before coming in with my own response.”


How teachers can use this: “I want to ask questions that stimulate discussion, but it’s always hard to check that I’m actually doing it…

“Earlier this week I was asking closed questions like, ‘Do mitochondria require cellular respiration to create energy?’ Now I’m asking more open-ended questions like, ‘How is energy produced in mitochondria?’ and student engagement has improved a bunch!


How teachers can use this: “It looks like my students acquire vocabulary best when I speak at an 11th grade level. That must be the sweet spot of their zone of proximal development.”

“Leslie is speaking at a Grade 2 reading level? Yikes. No wonder she didn’t turn in the assignment – she probably didn’t understand what I was asking for.”


How teachers can use this: “Hm… I really need to use more positive reinforcement. My kids did great today, but my language was still pretty negative.”

“I use way more positive phrases than other teachers, yet my students’ scores are below averageMaybe I need to increase the level of rigor in my classroom.”
