aspects have a high or very high degree. For more details, the following describes each aspect.
1. Socialization of Curriculum-2013
Socialization is the first step that must be prepared to implement Curriculum- 2013. Socialization of curriculum is important to give knowledge about the changes
of Curriculum-2013 to the ones who implement the curriculum as well as the whole school party, the society, and the parents of the students. Socialization can be done
proportionally and professionally by Ministry of Education and Culture of central government or regional government. In the school, socialization can be done by the
principal who knows and understands Curriculum-2013 or other highly competent persons from society, government, academics, writers, or education viewers.
Socialization of Curriculum-2013 should be conducted perfectly for many parties so that the new curriculum can be understood and applied optimally; moreover
socialization is an important step that determines the success of curriculum E. Mulyasa, 2014: 48.
Socialization of Curriculum-2013 includes these aspects, namely teachers knowledge of the development and implementation of Curriculum-2013, the essence
of changes of Curriculum-2013, The essence of Competency Standard of Graduates, Core Competence, Basic Competence, Implementation Strategy of Curriculum-2013,
and the essence of The Scientific Approach or Scientific Learning Models such as: Problem Based Learning PBL, Project Based Learning PjBL, Discovery Learning,
Authentic Assessment and Assessment Techniques of attitudes, skills, and
47
knowledge. The socialization of Curriculum-2013 has included all aspects of lesson plan, chemistry teaching-learning process, and evaluation of chemistry teaching-
learning Kemendikbud, 2013. The results showed that the degree of socialization of Curriculum-2013 is
high by the average percentage of 64.19. Out of 31 samples, there is 1 teacher with very low categories, 8 teachers with low categories, 7 teachers with moderate
categories, 12 teachers with high categories, and 3 teachers with very high categories. It would be reasonable that based on the data of sample qualification of chemistry
teachers in Sleman regency senior high schools, 80.64 of teachers have followed once, 16.13 have followed twice, 0 of teachers have participated in the
socialization of Curriculum-2013 for three times, and 3.23 of teachers have participated in the socialization of Curriculum-2013 for four times.
Compared to the research conducted by Lilik Prihastuti 2008: 41, socialization of Unit Level of Education Curriculum in chemistry teaching-learning in Kulon
Progo regency was very high category with the average percentage of 80.62. It was due to the fact that all of the chemistry teachers in Kulon Progo regency had followed
the socialization at the level of local, regional, and provincial scope. Teacher is the key in implementing the Curriculum. It can be achieved with a
good preparation, such as a long and sustained time of the curriculum socialization. It is easily understood that the curriculum concepts to the teachers should be done up to
the trial so that the teachers really understand how to implement Curriculum-2013 in
48
chemistry teaching-learning. Socialization of Curriculum-2013 needs to be improved in order to broaden the knowledge and skills of the teachers. Teachers also need to
continue to learn in order to follow the developments or changes that occur in curriculum.
