This study focused on determining the impact of supervisory monitoring scheme, particularly classroom observation, to the learners' performance. Forty-two teachers from 10 elementary schools in the District of Victoria, Laguna, Philippines became part of the study by undergoing classroom observations and answering the survey questions pertaining to the (1) teaching-and-learning process, (2) learners' behavior, (3) teachers' and learners' enthusiasm, and (4) effect to learners' performance.The authors made use of qualitative technique in doing research as responses to qualitative questions were recorded, sorted and analyzed. Themes were developed in the responses of teachers as situations with and without classroom observations are compared and contrasted.Is there a difference in the performance of learners when there is no formal classroom observation and when there is a formal one? Do learners got intimidated to participate when there are observers, or are they more motivated? This and more other concerns about supervisory monitoring scheme will be dealt with in this research.
