Abstract

Abstrak Observasi awal yang dilakukan terhadap 74 guru-guru di SMPN 1 Tanjung Morawa dan SMPN 4 Tanjung Morawa menunjukkan bahwa hanya 10 orang yang mengaku mampu melakukan penelitian tindakan kelas (PTK). Dari 10 guru-guru tersebut hanya 4 orang yang mengaku sudah melakukan penelitian tindakan kelas (PTK) dan 6 guru mengaku tidak termotivasi untuk melakukannya. Sementara 64 guru lainnya memberikan alasan tidak memahami prosedur pelaksanaan, PTK bukan pekerjaan seorang guru. Seyogyanya, pelaksanaan PTK tidaklah hanya sebagai disamping tuntutan administrastif, namun guru harus mampu untuk merefleksi pembelajaran di kelas demi peningkatan kualitas pembelajaran membutuhkan penelitian tindakan kelas. Hal inilah yang menjadi dasar peningkatan profesionalisme guru-guru SMP melalui pelatihan penelitian tindakan kelas di kabupaten Deli Serdang. Pelaksanaan Iptek bagi Masyarakat  (IbM) ini adalah untuk membentuk kelompok guru yang mandiri dalam melaksanakan PTK serta mampu menghasilkan laporan serta karya tulis imiah yang dipublikasikan dalam jurnal dengan pendekatan pendampingan yang berkelanjutan. Dosen-dosen yang sudah berpengalaman dalam hal PTK turut membantu sebagai pembimbing guru-guru tersebut. Pelaksanaan IbM ini memberikan kontribusi peningkatan motivasi guru dalam melaksanakan PTK secara signifikan dimana terdapat 13 orang dari 31 orang guru yang dibimbing dapat menuntaskan kewajibannya sampai pada seminar hasil PTK.  Kata Kunci : Jurnal Ilmiah, Penelitian Tindakan Kelas. Abstract Initial observations conducted on 74 teachers at SMPN 1 Tanjung Morawa and SMPN 4 Tanjung Morawa indicated that only 10 of them have the ability to perform classroom action research (PTK). More specifically, 4 out of 10 teachers have engaged with PTK and 6 teachers admitted that they are not motivated to do so. Accordingly, 64 other teachers had lack of understanding in the implementation procedure arguing that, PTK is not a teacher's job. As a matter of fact, the implementation of TOD is not only as a matter of administrative demands, but the teacher must be able to reflect on the classroom learning for the improvement of the quality of learning requires research of class action. This is the basis for improving the professionalism of junior high school teachers through classroom action research training in Deli Serdang district. The implementation of Science and Technology for Society (IbM) is to form a group of independent teachers in implementing PTK and able to produce reports and writings imiah published in the journal with a sustainable approach mentoring. Lecturers who have experience in terms of PTK helped as mentors of these teachers. The implementation of IbM contributed to the improvement of teachers' motivation in implementing PTK significantly where 13 people from 31 guided teachers could complete their obligation until the PTK seminar result. Keywords: Scientific Journal, Classroom Action Research.

Abstract

This study aims to look at how the role of gender in the creative thinking process of students, especially in solving math problems. This research is included in exploratory research with a qualitative approach. The qualitative approach was chosen because in this study the main data were written and/or spoken words. The subjects of this research are 1 semester students of mathematics education study program. The main instrument is the researcher himself while the assistive instrument uses problem solving tests, interview guidelines, and recording aids. The results of the analysis and discussion that have been done show that students who have different levels of thinking ability will also have different levels of creative thinking. Gender also influences the results of creative thinking, where in the subject of this study, the creative thinking ability of female students is better than that of men. Keywords: Creative Thinking Ability, Problem Solving, Gender Differences

This study aims to improve students' mathematical reasoning abilities through the Integrated Problem Solving learning model in a scientific approach with the help of geogebra for class X students of SMA Bina Bersaudara Medan. The subjects in this study were 47 students of X-MIA class at Bina Bersaudara Private High School Medan. From the initial ability test, it was obtained that the average score of students was 2.41 which was included in the low category and 42.55% who completed. After being given action in cycle I and given a mathematical reasoning ability test, it was obtained that the average score of 2.79 students was included in the moderate category (53.19%) who passed. In cycle I, the percentage of completeness of mathematical reasoning had not been achieved, so cycle II was carried out. After being given action in cycle II and given a mathematical reasoning ability test, an average score of 3.03 was obtained in the good category and 87.23% had completed. From cycle I to cycle II, an increase in the average score and the percentage of mathematical reasoning completeness were obtained.
