Abstract-The aim of this research was to develop evaluation instruments for scientific writing instruction with a constructivism approach. In order to achieve the research objectives, the combined models of development, 4D and RDR were used. The design of this research that included four stages, namely the preliminary study, define, design, and development. The research data were quantitative and qualitative. Data analysis techniques were the domain technique and t test statistical. Based on the results, the obtained development product in the form of the evaluation of the instruction of writing scientific papers were valid and reliable. The development product consisted of four types of evaluation devices, the assessment rubrics, portfolios, observation sheets, and learning journal. Based on the results of the four development products, the effectiveness test was valid and reliable so that it can be used to conduct evaluation of learning to write scientific papers with constructivism approach, both for the evaluation of the process and the evaluation of the learning outcomes. The result of this development research implies that the product of this development research was valid and reliable, and feasible and reliable for using in scientific writing instruction because haved been through a lengthy development process and systematically.
