Analysis of Physics Textbooks Used in Senior High School for Insertion of the Nature of Science

Abstract

The study analyzed two grade X physics textbooks published by Erlangga and Yudhistira. The analyzed textbooks emphasized the insertion of four aspects of the nature of science (NOS), consisting of science as a body of knowledge, science as a way of investigating; science as a way of thinking; and science and its interaction with technology and society. The content analyzed is the subject matter in the odd semester. The raters consisted of one physics lecturer (rater 1) and two teachers (rater 2 and 3). The raters used the scoring rubric developed by the researchers based on indicators from the four aspects of NOS. The results stated that Erlangga’s Textbook inserted (a) the first 58.46% of the NOS aspects; (b) 26.28% second aspect of NOS; (c) 31.78% of the third aspect of NOS; and (c) 16.86% of the fourth aspect of NOS. Also, the results in Yudhistira’s book revealed that (a) the first 49.55% of the NOS aspects; (b) 13.88% second aspect of NOS; (c) 24.55% third aspect of NOS; and (d) 12.01% of the fourth aspect of NOS. The percentage of inter-rater agreements ranged from 70-88%. The percent agreement strengthens with the interval of kappa value from 0.60 to 0.88. The results indicated that the two books devoted half of the learning material that reflected science as a body of knowledge but neglected science as a way of investigating, and science and its interaction with technology and society.
