Between April 17 and 19, two experts from Columbia University Center for Professional Education of Teachers (CPET) Faith Little and Brian Veprek visited our school. During 3 days, our guests observed classes accompanied by our administrators, participated in meetings and watched Hisar’s activities in order to get acquainted with the daily life at Hisar prior to our collaboration with Columbia University Center for Professional Education of Teachers (CPET). Expert trainers also organized a seminar on “Critical Thinking” for our academic staff on April 17.
