We have entered the 21st century, known as the knowledge century. The future forecasters(futurist) said that as the century of knowledge because knowledge would become a cornerstone of all aspects of life (Trilling and Hood, 1999). Century is an era of knowledge to the demands of a more complex and challenging. An era with certain specifications that are very large influence on the education and employment. The changes that occur in addition due to extremely rapid technological development, also caused by extraordinary developments in science, psychology, and the transformation of cultural values. The outcome was a shift in perspective of human to human, way of looking at education, changes in the role of parents / teachers / lecturers, as well as changes in the pattern of relations between them.
Trilling and Hood (1999) suggested that the primary concern of education in the 21st century is to prepare to live and work for the community. It's time for a moment turned towards the wide-angle view of the main roles will increasingly be played by learning and education in a knowledge-based society.
Deterioration of our education has been felt for many years, where the curriculum repeatedly identified as the problem. This is reflected by the effort to change the curriculum started in 1975 replaced by a curriculum curriculum 1984, then replaced again with the 1994 curriculum. Nasanius (1998) revealed that the deterioration of education is not caused by the curriculum but by the lack of professionalism of teachers and the reluctance of student learning. Professionalism as a support teacher fluency in performing their duties, is strongly influenced by two major factors are internal factors that include interest and aptitude and external factors that is associated with the environment, infrastructure, and various exercises that teachers do. (Sumargi, 1996) Professionalism and teachers education personnel remain inadequate in terms of its main scientific fields. For example, Biology teachers can teach Chemistry or Physics. Or social studies teachers to teach Indonesian. Indeed the number of educators in quantitative enough, but the quality and professionalism has not been in line with expectations. Many of them are not qualified and the wrong material convey that they are not or less able to present and provide education that is really good quality (Dahrin, 2000).
Many factors cause the lack of professionalism of a teacher, so the government has been trying for teachers who perform in the century of knowledge is the teacher who really professionals who are able to anticipate the challenges in education especially in science.
