Facilitators in the workshop helped the participants prioritize the problems in two aspects: ease of solving the problem and financial cost. Each problem was classified into the following groups: ‘easy and does not need much money’, ‘difficult but does not need much money’, and ‘needs money’. This categorization was created to motivate participants from schools with a lack of funds. To enhance self-efficacy of teachers in the first instance, we placed value on feasibility rather than general importance.
