Abstract

The objectives of this classroom action research are: to optimize leaf structure using Quatum method to increase understanding in grade IV students of State Primary School of Kroyo 1 in Karangmalang Subdistrict, Sragen Regency, in the academic year of 2017/2018 and explain how to implement quantum learning model in improving science learning outcomes at leaf structure structure of grade IV students of State Primary School of Kroyo 1 in Karangmalang Sub-district, Sragen Regency in the academic year of 2017/2018. The objective of this research is to improve the cognitive ability in Natural Science through the Quantum learning method of the students in Grade IV of State Primary School of Kroyo 1 in Karangmalang Sub-district, Sragen Regency in the academic year of 2017/2018. This research is a classroom action one with two cycles. Each cycle consisted of four phases, namely: planning, implementation, observation, and reflection. The subject of the research was all of the students in grade IV of State Primary School of Kroyo 1 in Karangmalang Sub-district, Sragen Regency in the academic year of 2017/2018. Its data were gathered through observation, document analysis (content analysis), and in-depth interview. The data were then analyzed by using an interactive model of analysis comprising three components, namely: data reduction, data display, and conclusion drawing or verification. The result of the research shows that there is an improvement of cognitive ability in Natural Science of the students in grade IV of State Primary School of Kroyo 1 in Karangmalang Sub-district, Sragen Regency in the academic year of 2017/2018, who were taught with the Quantum learning method. This is indicated by their cognitive tests. Prior to the treatment, the average score of their cognitive test is 76,53, and the percentage of the students completing the learning is 71,8%. Following the treatment of cycle I, the average score improves to 81,41 and the percentage of students completing the learning is 79,49%. After the treatment of cycle II, the average score improves to 87,31, and the percentage of the students completing the learning is 100%
