The validity analysis shows that the average score obtained is 91.6. The criteria for practicality are seen from the results of the analysis of the subject teacher's assessment with an average score of 96

Pengembangan Multimedia Interaktif Berbasis Web dengan Pendekatan Project Based Learning

The development of geogebra web-based interactive media using cybernetix boards with a Project Based Learning (PjBL) approach is a process of developing interactive media that can display mathematical concepts needed by students and can combine images, videos, and worksheets in one geogebra web page and display on a web page. cybernetix board that supports media for students to use together. The purpose of this research is to produce interactive learning media and to know the validity of the resulting product. The method used in this research is a research and development method, the design used in the development of this interactive multimedia is a 5-step design model of Borg and Gall. The results of the validation of learning media products from material experts obtained a percentage score of 97.5% with a valid predicate. The results of the validation of media design experts obtained a score of 90% with a valid predicate. The validation of learning experts obtained a percentage score of 97.5% with a valid predicate.

KARAKTERISTIK BERPIKIR KREATIF SISWA KELAS VII SMP N 1 KRAGAN DALAM MEMECAHKAN DAN MENGAJUKAN MASALAH MATEMATIKA MATERI PERBANDINGAN DITINJAU DARI GAYA KOGNITIF

Abstract: The research objectives were to determine and to describe creative thinking characteristic of 7th grade students of SMP N 1 Kragan in solving and proposing problem at comparative case seen from the cognitive style. This research belonged to descriptive research by qualitative-explorative approach. The sample was taken by purposive sampling technique. The subjects being used in this research were 4, those were 2 students with field dependent cognitive style and 2 students with field independent cognitive style. The subject grouping based on cognitive style was taken by group embedded figures test. There were two instruments that were used to collect the data of this research. The first instrument was solving and proposing problem test instrument. The second was interview guidance. They were validated by using the time triangulation test and the reference fulfillment. The data were analyzed using a Miles and Huberman’s concept, that was data reduction, presentation, and conclusion.. The results of this research show as follows, (1) Creative thinking characteristics of students who had field dependent cognitive style in solving and proposing problem were as follows. The fluency aspect was shown by the students through 4 stages of creative thinking process, both in solving and proposing the problem. The four stages were preparation stage, incubation stage, illumination stage, and verification stage. The flexibility aspect in solving problems appeared when the students gave the other alternative answer, whereas this aspect was not fulfilled in proposing the problems.  The originality aspect was not fulfilled in solving and proposing problems. (2) Creative thinking characteristics of students who had field independent cognitive style in solving and proposing problem were as follows. The fluency aspect was shown by the students through 4 stages of creative thinking process, both in solving and proposing the problem. The four stages were preparation stage, incubation stage, illumination stage, and verification stage. The flexibility aspect in solving problems was shown when the students gave the other alternative answer, while in proposing the problem this aspect was not completed because students were able to make only one question. The originality aspect in solving the problem could be seen when the students gave a new way solution and this  was different from the previous one. Meanwhile in proposing the problems, aspet of originality was not fulfilled.Keywords:   creative thinking characteristics, solving  problems, proposing problems, cognitive styl
