The study was designed to investigate technology and engineering teachers' metacognitive awareness during specific established teacher practices. The study had a sample size of 18. There were six participants in three groups. Group 1 consisted of teachers that actively participated in Transforming Teaching through Implementing Inquiry (T2I2) professional development program. Group 2 consisted of teachers that were selected for but did not actively participate in T2I2 professional development system. Group 3 consisted of teachers that completed the National Board for Professional Teaching Standards professional development program. To measure the metacognitive awareness of each group, a semi-structured open-ended interview was used. The interviews were analyzed by two independent coders using a coding rubric. The coded interviews established the phenomenological metacognitive awareness of each group.
