Abstract


The purpose of this study was to obtain a pre-conception of learners and scientists perspective on the concept of climate change, global warming and relations between them; know the characteristics of teaching materials; and find an expert assessment of the design of instructional materials. The method used in this study is a mixed methods using sequential eksploratorisdesign by adapting the Model of Educational Reconstruction(MER). Instruments are interview form, text analysis sheet, validation indicators sheet and cognitive aspects of learning objectives and affective aspects, validation concept analysis sheet, validation design teaching materials sheet, readability test and scientific literacy test.

Characteristics of teaching material produced are (a) developed accordance reflection of learners pre-conceptions and the scientist's perspective (b) accessible, (c) equipped with aspects of nature of science (NOS), and (d) using a sequence of teaching and learning of Science and Technology Literacy (STL) by adopting a learning phase Chemie im a Context (ChiK). The results of the validation of teaching materials to obtain an average value of CVI is 0,99. Results of the questionnaire responses obtain an average value of 4.46, while the test results showed therewere also significantly differences in the value of literacy students between before with after studying the teaching materials (p=0,00).
