Abstract

Abstract.The purposeofthis studyistodevelop aNCTMprocess standards based worksheet. Thedevelopment Researchmodelrefers toThiagarajan4-D model. It consistsoffourstages, namelydefine stage, design stage,development stage, and disseminate stage.Thereare twoproductsthis research. Theyareworksheets andfinaltestinstrument. The worksheetconsistsoffiveprocess standards, namelyproblem solving, reasoningandproof, communication, connections, andrepresentation. All productsobtainedin this research have satisfied validity, practicality and effective criteria. Their scores are respectively4.33forvalidity, 89.55% forpracticality, 88 % foreffectiveness. It can be concluded that those products can be used as mathematics learning material in a class.
