CHAPTER III RESEARCH METHOD

A. Research Design

This research is a quantitative descriptive research using three variables. The first variable is the degree of implementation of Curriculum-2013 in chemistry teaching- learning by chemistry teachers in Sleman regency with four sub-variables: 1 socialization of Curriculum-2013, 2 preparation of lesson plan, 3 chemistry teaching-learning process opening activity, core activity, and closing activity, and 4 evaluation of chemistry teaching-learning. The second variable is the correlation between socialization of Curriculum-2013 and the preparation of lesson plan, chemistry teaching-learning process, and the evaluation of chemistry teaching- learning. The third variable is constrains faced by teachers in implementing Curriculum-2013 in chemistry teaching-learning.

B. Time and Research Place

This research was done in 3 December 2014 until 16 January 2015. The place of this research is in senior high schools in Sleman Regency, Special Region of Yogyakarta. 30

C. Operational Definition of Variables

1. The degree of implementation of Curriculum-2013 in chemistry teaching- learning is the percentage of the belonging sub-variables faced by teachers. a. Socialization of Curriculum-2013 includes: socialization which conducted by schools or other relevant parties, teacher‟s understanding to the aspects of Curriculum- 2013 changes, and teacher‟s understanding to all components that support chemistry teaching –learning based on Curriculum-2013. b. Preparation of lesson plan includes teacher‟s understanding and experience to the model, way to choose subject matter from the syllabus, learning resources, media, models, methods, scenarios, and the design of assessment. c. Chemistry teaching–learning process includes opening activity, core activity, and closing activity. Opening activity includes giving apperception, linking the subject matter, and telling the benefits, competences, and teaching – learning objectives. Core activity includes mastering the subject matter, giving creative teaching-learning, timeliness, asking question, answering question, facilitating learners, and giving assessment. Closing activity includes facilitating and guiding the students to summarize and reflect, giving test and portfolio assignment, providing direction, and telling the next teaching – learning plan. d. Evaluation of chemistry teaching–learning includes the performance of teachers to conduct the assessment to the competence of attitudes, knowledge, and skills with various types of test. 31 2. The correlation between socialization of Curriculum-2013 and the preparation of lesson plan, chemistry teaching –learning process and evaluation of chemistry teaching –learning is analyzed by product moment correlation by comparing the calculation and from the table. 3. The constraints to the implementation of Curriculum-2013 are teacher‟s experiences in participating the socialization of Curriculum-2013, the preparation of lesson plan, chemistry teaching-learning activities, and the evaluation of chemistry teaching –learning.
