Abstract

This study aims to develop intertextual learning strategy with POE (Predict-observe-explain) which has the potential to improve the mastery of the concept of the effect of nature of reactants and catalysts on reaction rates, and students science process skills (SPS). The method used in this research is Research and Development (R&D) which is limited to the preliminary product development stage. The instrument used was the the format for the suitability of learning activities with the conceptual mastery indicator and the science process skills validated by 5 chemistry lecturers. The results obtained intertextual-based learning activities involving three levels of chemical representation with POE learning steps to build the concept of the effect of nature of the reactant and catalyst on reaction rates and develop students^ science process skills. The strategy consist of five phenomenon which followed by three experiments and two videos as observation tools for the student. The explanation stages guided by sets of guiding questions which involve multi representation levels in those explanation. The product of this research is expected to be used as an alternative learning strategy that can be used by teachers to minimize the possibility of misconceptions that occur, increase mastery of concepts, and students SPS.
