Abstract
Vocational senior high schools will have been cooperating by the year of 2020. They must adjust to the competencies of each region to achieve 60% of vocational high school and 40% of senior high school ratio. However,the fact shows that they have not met the required competencies since only 49% of vocational and 51% of senior high school ratio have been earned. The number of senior high schools will be minimized but vocational high school will be increased due to the consideration of the internal challenges in the year of 2020, in which the Indonesian population will overflow so that it needs efforts to use human resources especially those of productive age to be useful nor being burden for the national development. Thus, the way to achieve this aim is to transform human resources who have the competence and skills through education (rule of
government, number 70 in 2013). The design of this research is developmental research, which develop task to solve trigonometry problem. The model of teaching and learning sets developed in this research relates to modified 4-D models, consisting of ; to define,design, and develop.
