Abstract

Didunia yang begitu cepat berubah, tingkatan berfikir kritis akan menentukan daya tahan seseorang dalam berkompetisi untuk menjadi yang terunggul.  Kemampuan berfikir kritis adalah kemampuan yang penting karena dapat mengembangkan dan menyatakan ide-ide penting, membantu kita dalam mengkaji gagasan-gagasan yang rumit secara sistematis untuk dapat memahami lebih baik sehingga mencegah orang-orang untuk membuat keputusan yang buruk dan membantu mereka dalam memecahkan masalah. Sementara itu, hampir setiap bidang kehidupan manusia memerlukan kemampuan pemecahan masalah. Bahkan, kesuksesan dalam kehidupan sangat ditentukan oleh kemampuannya dalam memecahkan masalah baik dalam skala besar maupun kecil. Dalam hal ini berfikir kritis menjadi syarat yang penting bagi setiap orang untuk memecahkan masalah.Banyak pendapat para ahli tentang pengertian berfikir kritis. Secara umum berfikir kritis dapat didefinisikan suatu proses penggunaan kemampuan berpikir secara efektif yang dapat membantu seseorang untuk membuat, mengevaluasi, serta mengambil keputusan tentang apa yang diyakini atau dilakukan. Dari definisi tersebut dapat maka   berpikir kritis mempunyai  ciri-ciri: (1)  menyelesaikan suatu masalah dengan tujuan tertentu, (2) menganalisis, menggeneralisasikan,mengorganisasikan ide berdasarkan fakta/informasi yang ada, dan (3) menarik kesimpulan dalam menyelesaikan masalah tersebut secara sistematik dengan argumen yang benar. Berfikir kritis sangat diperlukan dalam proses pembelajaran disemua mata pelajaran termasuk matematika.  Dalam pembelajaran matematika kemampuan berfikir kritis akan sangat dibutuhkan dalam proses memahami konsep, menganalisa masalah dan menentukan solusi yang tepat dari sebuah permasalahan di matematika.Hubungan antara berpikir kritis dan pemecahan masalah menarik untuk dikaji. Selama ini pemecahan masalah sering dipandang sebagai keterampilan yang bersifat mekanistis, sistematis, dan abstrak. Namun, seiring berkembangnya teori-teori belajar kognitif, pemecahan masalah lebih dipandang sebagai aktivitas mental yang kompleks yang memuat berbagai keterampilan kognitif. Dalam konteks sebagaimana diuraikan di atas, berpikir kritis dipandang sebagai syarat bagi tumbuhnya kemampuan pemecahan masalah. Namun, sebaliknya, pemecahan masalah dapat pula dipandang sebagai sarana untuk menumbuhkan kemampuan berfikir kritis. Perlu diketahui bahwa pemecahan masalah mempunyai berbagai peran, yakni sebagai kemampuan, pendekatan, dan sebagai konteks. Mengingat kemampuan berfikir kritis tidak tumbuh dalam suasana atau ruang hampa, maka ia memerlukan sarana atau konteks. Dalam hal ini, konteks dimaksud dapat berupa aktivitas pemecahan masalah. Dalam makalah ini akan dieksplorasi mengenai hubungan antara pemecahan masalah dan berpikir kritis ditinjau dari berbagai aspeknya.

Abstract

Perkembangan dan kehadiran teknologi komputer telah memberikan kemudahan berbagai pihak untuk meng- gunakannya dalam bidang kehidupan,  termasuk pendi- dikan, sebagai sarana penunjang pendidikan. Komputer semakin memberikan manfaat yang besar di dunia pen- didikan, khususnya dalam proses pembelajaran. Terdapat ratusan bahkan ribuan program aplikasi komputer atau perangkat lunak yang dapat dimanfaatkan untuk pembe- lajaran matematika, khususnya Aljabar Linier. Salah satu perangkat lunak bantu yang dapat digunakan dalam pem- belajaran Aljabar linier yaitu Matrix Laboratory (MATLAB). Program ini dapat dimanfaatkan untuk meningkatkan kecepatan, dan keakuratan dalam berbagai  perhitungan dalam pembelajaran aljabar linier sehingga waktu yang di- perlukan untuk mengerjakan lebih esien dan hasil yang diperoleh lebih akurat dibandingkan dengan perhitungan yang dilakukan secara manual, selain itu juga dapat mem- visualisasikan grak dalam bentuk 2 dimensi maupun 3 dimensi, misalnya dalam penyelesaian Sistem Persamaan Linier sehingga diharapkan dapat meningkatkan pemaha- man terhadap materi yang diberikan.

Abstract

This study aims to determine the effect of linguistic intelligence on students mathematical connection ability in solving open-ended problems on the trigonometric material. Linguistic intelligence is the ability to use and process words effectively both verbally and in writing with appropriate or appropriate meaning. The ability of mathematical connections is the ability to associate mathematical concepts between mathematical concepts, linking mathematical concepts with other fields of science and linking mathematical concepts with everyday life. Students who have mathematical connection skills can solve life problems or challenges faced by connecting mathematical concepts. Mathematical connection ability requires linguistic intelligence which refers to Howard Gardners opinion to solve open-ended problems that have more than one solution. This research is a quantitative research involving 116 students. The research was carried out by survey method and data analysis method using simple linear regression analysis. While data collection is done by questionnaire and test. Based on the results of the study formed a simple linear regression equation Ŷ = 21.26 + 0.62X, which means that linguistic intelligence influences the ability of students mathematical connections in solving open-ended problems and gives an effect of 38.13%. Thus, linguistic intelligence has a significant influence on the ability of mathematical connections of Walisongo UIN mathematics students in solving open-ended trigonometric material problems.

Abstract

This development research is motivated because students need practical teaching materials when studied in class or outside the classroom. Religious characteristics and politeness of low students demand to reduce character values in teaching materials, so as to improve learning achievement and improve the character's value of participants student. This research is a type of R & D research with the procedure for developing pocket books using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subject of this study was the students of MA Sunan Katong class X with data analysis techniques using descriptive qualitative and quantitative. Based on the results of the study it can be concluded that mathematical pocket books based on character education on trigonometry material are feasible to use. Test the validity by evaluating the validator included in the valid category but needs to be slightly revised with an average percentage of 70.80%. The response of students to pocket books is included in the excellent category with a percentage of 86.60%. The results of the t-test get the result t_count = 2,248> t_table = 1,668 then H_1 is accepted. This means that the class average using mathematical pocket books based on character education is better than those that do not use pocket books. The n-gain score is 0.34. This shows that learning uses a pocket book of trigonometry based on character education to effectively improve the character education of students in the medium category.

Abstract

This study aims to identify how the process of critical thinking of prospective teachers in solving mathematical problems in the Department of Mathematics Education, Faculty of Science and Technology, Walisongo State Islamic University, is viewed from a qualitative learning style. The purposive sampling method was used to determine six prospective teachers as research subjects. Each visual, auditory, and kinesthetic learning style is represented by 2 subjects. The auxiliary instruments in this study consisted of a learning style questionnaire, a critical thinking ability test, and an interview guide. Critical thinking indicators were developed through consideration of the main elements of FRISCO, the level of cognitive thinking according to Bloom and the Steps of Problem Solving According to John Dewey. Data processing through the stages of data collection, data reduction, and data verification with the triangulation method. The results of the study show that auditory and kinesthetic learning styles have lower critical thinking process characteristics than visual learning styles in solving math problems. From the interview process it was revealed that the ability to argue based on valid and logical facts, all types of learning styles is still quite low. However, all three have strong potential to develop critical thinking skills through stimulation from educators.
