Abstract
The learning of organic chemistry in Study Program of Chemistry Education, FKIP UR has not been using an effective, innovative and valid of student^s work sheet (SWS). Lecturers try to develop of SWS based on contructivism in organic chemistry II course. The formulation of the problem in the research is: how to develop SWS based on constructivism that valid in organic chemistry II course?. The type of this research was R and D (reseach and development) with the 4-D development model which include Define, Design, Develop, and Disseminate. This research was to develop phase and be continue with a definite tryout. This research was conducted in FKIP Universitas Riau. The object of this research was the SWS based on the contructivism at material aldehyde ketones, carboxylic acids, amines, and free radicals. The data analysis technique used for this research was descriptive statistic. The descriptive analysis done by calculated the percentage of validation value. The average score of valuation to five expediency aspect of SWS by validator^s team, such as the didactic, construct (course and language), technical and characteristic of constructivism has expediency value continued is 94,66%, 98,44%, 96,29%, 92,20% and 95,02%. Thus, the average score totality of SWS based on the contructivism subject of organic chemistry II is 95,32% which is in valid criteria, means that the SWS developed is proper to be use. Whereas percentage response of student to SWS is 85,90% with very good criteria.
Keywords: Development, Student^s Work Sheet, SWS, Contructivism, and Organic Chemistry II.
