The document describes an online math coaching program called Math Coach that was started in 2009 in Sweden. Volunteer coaches from universities provide math support to students aged 12-19 online from 5-8pm during semesters. Over 8,000 hours of conversations have been archived from over 16,500 conversations. The program is based on Vygotsky's zone of proximal development and Bloom's 2 sigma problem. The relationship between coaches and students is analyzed using a modified community of inquiry framework called the relationship of inquiry framework, which examines teaching, cognitive, social, and emotional presence. A survey found high ratings in these presences. Transcripts are also being analyzed to understand the model further.
