Developing Inquiry Model-Based Device to Increase Learning Results Skill Writing a Scientific Balance of Biology Projects

Abstract

Success in the learning process is not only judged from the ongoing process but ongoing processes and learning models that meet the needs of the students. The learning model helps teachers in classroom teaching especially practitioners writing scientific reports. One way to solve this problem is to use the Inquiry learning model. The purpose of this Research and Development research is to design and develop the Inquiry learning model by assessing the validity / quality, practicality and effectiveness in the learning process of Biological Sciences for grade VIII students. The development procedure was carried out by adopting Borg and Gall's modified development design by Sugiyono consisting of nine stages: identification of problem and potential, data collection and product design, validation of Design expert, design revision, product trial, product revision one, second product revision, and final product. The validity and practicality of the product were analyzed using the percentage improvement of the students' pretest and posttest scores. Product validation is very good (97.11% improvement), the practicality measured through the assessment of respondents is also very practical (87.37%). In conclusion, Inquiry learning model able to give skill to students and positive impact in writing scientific report so that their learning more effective with 34, 74%.
