Ideally, it would be valuable to capture team teaching electronically to develop a knowledge base of team teachings that would provide knowledge that could be used in future team meetings.
As a particular manifestation of practice-based professional development, videos focus participants' thinking and talk on artifacts from real classrooms and capture teaching in all of its complexity while, at the same time, affording space and time for guided reflection (Miller & Zhou, 2007; Sherin, 2004).
As a particular manifestation of practice-based PD (Ball & Cohen, 1999; Gallucci et al., 2010; Loucks-Horsley et al. 2010), videos focus teachers' learning on real classrooms and capture teaching in all of its complexity while, at the same time, affording space and time for reflection (Fishman et al., 2014; Miller & Zhou, 2007; Sherin, 2004; Zembal-Saul, 2008).
As is practice in qualitative case study, the aim was to elicit rich data (Geertz 1988; Stake 2013) that would capture participants' backgrounds, teaching or learning philosophies, expectations and plans, day to day activities, what they considered when they took decisions about their teaching or study, and barriers and enablers that they encountered.
In one series of fly-on-the-wall photographs, van der Elsken captures Jean Michel teaching a girl to "smoke hashish in the right way … the cigarette not held in the mouth, the smoke inhaled together with air from the cupped hands".
Furthermore, it is hard to make a statement if the preference measure actually validly captures future teaching practice.
After using motion capture to teach the machine Machii's cutting techniques, the Yaskawa Electric Company captured a series of swordsmanship tests with man and robot side-by-side in the video below to see if a computer program could trump years of training and certified excellence.
Most of these aspects (seven out of nine), especially adjustment for quality of care and capturing hospitals' teaching activities, were weakly handled in most of the studies.
Kane and Cantrell (2013) found that two trained individuals observing the same 45-min session of a teacher's class captured instructor teaching methods as well as having four independent observations of four different class sessions, indicating that fewer classes can be observed if two observers are used.
This taught me discipline".
