Abstract

Development of worksheet based on problem based learning model for buffer solution topic had been conducted and implemented in XI IPA 3 class of SMA N 1 Indralaya. This research was conducted by Rowntree development design includes the planning, development, and evaluation phase that modified with a Tessmer formative evaluation (expert review, one-to-one, small group, and field test). The result of this research indicate that validity test of desain 0.83 of Aiken’s coefficient with high category and 0.692 of Kappa’s coefficient with good category, the validity test of pedagogic 0.94 of Aiken’s Coefficient with high category and 0.609 of Kappa’s coefficient with good category, and the validity test of content 0.79 with high category and 0.738 of Kappa’s coefficient with good category. Practicality level are known from the result questionnaire in one-to-one phase 0.783 of cronbach’s alpha with high category (practical) and small group phase 0.836 with high category (practical). In field test phase are obtained the n-gain score 0.73 with high category (very effective). The effectiveness that has been obtained illustrates that this product has been able to increase the students learning result. The result of this research is a worksheet based on problem based learning of chemical buffer solution topic in XI SMA which are valid, practical, and effective. Keywords : Development, Worksheet, Problem Based Learning, Buffer Solution.
