Efektivitas Model IDEAL Problem Solving Berbasis Soal Open-Ended Terhadap Kemampuan Berpikir Kreatif Siswa Kelas VII

AbstractThe ability to think creatively plays important role in students’self development in the 21st century. This study aims to determine the effectiveness of the IDEAL Problem Solving learning model based on open-ended questions on students' creative thinking abilities. This study is a quantitative quasi-experimental study with a Pretest-Posttest Control Group Design. The subjects of this research were class VII students of SMP Negeri 3 Kartasura which consisted of 64 students. Clusters random sampling was used as the sampling method. Data collection was carried out using test techniques in the form of pretest and posttest as well as non-test techniques in the form of observation and documentation. Analysis of the research data was carried out by normality test, homogeneity test, independent sample t-test and n-Gain test with the help of SPSS 23. The hypothesis test with the independent sample t-test showed the number 0.000, which means H0 was rejected and H1 was accepted, meaning that the IDEAL Problem Solving learning model is effective increasing student’s creative thinking. Skills. The n-gain test in the experimental class was 0,56 (effective enough), while in the control class the n-gain percentage was 0,08 (ineffective) where the experimental class used the IDEAL Problem Solving model so that it can be concluded that the IDEAL Problem Solving Model quite effective in improving the creative thinking skills of class VII students at SMP Negeri 3 Kartasura in the subject matter of Science Objects and Its Observations.Keyword: Learning Model, IDEAL Problem Solving, Creative ThinkingAbstrak Kemampuan berpikir kreatif berperan penting dalam pengembangan diri siswa pada abaf 21.
