A project-based learning and Trello application (SUPERTRAP) as an innovative model of academic supervision to improve teachers’ teaching skills

Abstract

The academic supervision conducted by principals is perceived as not effective enough that it has not fully been impactful to the improvement of a teacher's teaching skill. This research aimed to get the overview of academic supervision with its weaknesses and challenges and to develop an innovative model of academic supervision as guidelines for the academic supervisor. This research employed Borg and Gall’ research and development model that included the following steps: research and information collecting, planning, developing the preliminary product (prototype development), preliminary field testing, and main product revision. Data was collected using observation, questionnaire, and focus group discussion (FGD). That is developing the preliminary product of academic supervision that was based on Trello application with PjBL and Gallery Walk. The data was analysed using Miles & Huberman qualitative descriptive model and quantitative descriptive analysis. The result of this research is a new model of the academic supervision named SUPERTRAP, which was developed as a project-based learning, gallery walk, and Trello. SUPERTRAP model consists of supervision design using Trello, SUPERTRAP model picture, a model description containing the supervision syntax based on Glickman’s academic supervision steps with Trello's features, and a user guide. The SUPERTRAP Model, which has shown excellent results, has been validated by experts and tested on principals and teachers, and, thus, it is ready to implement. The contribution of this research shows a combination of contextual concepts of academic supervision by integrating information technology and the gallery walk method as a participatory approach.
