Daily development logs can replace alot of the what have you done? What are you struggling on? conversations that happen in standups. Given that development can be very reductive and introspective having to retell the problem post-fact when your understanding isn't fully formed is a major challenge for some.
Create a shared Google drive folder and give each dev a log to prepend what they're doing each day as they do it. Then review and discuss solutions adhoc or in the stand-up.
