Banyak faktor yang menyebabkan masalah ini, diantaranya adalah orientasi akademik siswa. Perilaku menyontek dalam penelitian ini dikategorikan menjadi nilai kepribadian menyontek dan kuantitas praktik menyontek siswa. Penelitian ini bertujuan : 1) untuk mengetahui hubungan antara goal orientation dengan nilai kepribadian menyontek siswa Sekolah Menengah Pertama pada pelajaran matematika. 2) untuk mengetahui hubungan antara nilai kepribadian menyontek dengan kuantitas praktik menyontek siswa Sekolah Menengah Pertama pada pelajaran matematika. 3) untuk mengetahui hubungan antara goal orientation dengan kuantitas praktik menyontek siswa Sekolah Menengah Pertama pada pelajaran matematika. Jenis penelitian ini adalah penelitian deskriptif kuantitatif. Subyek penelitian adalah siswa kelas VII Madrasah Tsanawiyah Negeri 4 Demak yang diambil 26 siswa dengan random sampling. Metode pengumpulan data yang digunakan adalah angket, soal tes matematika, observasi, dan wawancara. Data penelitian ini dikumpulkan dengan mencari nilai dari masing-masing variabel, yaitu 1) nilai goal orientation, 2) nilai kepribadian menyontek, dan 3) nilai kuantitas praktik menyontek. Analisis data menunjukkan bahwa bahwa ada hubungan yang signifikan antara goal orientation perilaku menyontek siswa. Hal ini dapat dilihat dari ketiga hasil uji hipotesisnya yaitu: (1). Ada hubungan yang signifikan antara goal orientation dengan nilai kepribadian menyontek. (2).

Salah satu penyebab adalah rasa kebosanan, kesulitan dan ketakutan siswa terhadap pelajaran matematika serta anggapan ketidakgunaan pelajaran matematika dalam kehidupan sehari-hari khususnya materi geometri dan pengukuran. Pada akhirnya melemahkan daya kreatifitas dan kemandirian siswa dalam belajar. Tujuan penelitian ini adalah meningkatkan kemampuan pemecahan masalah matematika materi keliling dan luas bangun segiempat pada siswa kelas VII A di SMP Negeri 33 Semarang dengan penerapan “Rute Emas” sebagai salah satu desain Math Trail suatu pembelajaran di luar kelas. Pada peta “Math Trail” atau setiap titik petunjuk penjelajahan siswa dapat merumuskan, mendiskusikan, dan memecahkan masalah matematika yang menarik. Kegiatan Math Trail dapat dilakukan sendirian atau berkelompok untuk saling bekerja sama untuk memecahkan permasalahan. Penelitian ini merupakan penelitian tindakan kelas meliputi 4 langkah: planning, actuating, observation, dan reflecting. Hasil penelitian menunjukkan bahwa Hasil tes rata-rata kelas pada siklus pertama dan kedua mengalami peningkatan dari  73,66 menjadi 75,05 serta prosentase banyaknya siswa yang mendapat nilai minimal 67 adalah 23 siswa (74,19)% menjadi 27 siswa (87,10%).

In the end it weakens the creativity and independence of students in learning. The purpose of this study was to improve the mathematical problem solving abilities of the surrounding and wide-area quadrilateral in students of class VII A in 33 State Junior High School Semarang by applying \"Golden Route\" as one of the Math Trail designs for learning outside the classroom. On the \"Math Trail\" map or each exploration point of instruction students can form, discuss, and solve interesting mathematical problems.

Respons siswa sebesar 76% menunjukkan respons yang positif terhadap perangkat pembelajaran berupa LKS. \u0000Kata kunci: model Problem Based Learning, kemampuan pemecahan masalah matematis. \u0000  \u0000ABSTRACT \u0000This study aims to develop learning tools in the form of RPP and LKS based on Problem Based Learning in the function material for high school students which is oriented to problem solving abilities. The quality of the product being developed is assessed based on the validity, effectiveness, and response of students to the LKS. The learning tool development procedure refers to the 4-D development model, namely Define, Design, Develop, and Disseminate (Distribution). Because of the limitations of the author, the writing is done up to the develop stage. The subjects of this study were 36 students of class X MIPA 1 as many as 36 students in SMAN 1 Karangwareng. The instruments used to measure the quality of learning tools developed are lesson plan assessment sheets and student worksheets to measure validity, test problem solving abilities to measure effectiveness, and questionnaires to students' responses to worksheets. Validity quality of learning devices meets valid criteria based on average RPP scores from five validators, namely 91% with very good criteria and an average score of LKS from five validators, namely 92% with very good criteria. The quality of the effectiveness of learning devices meets the effective criteria based on the results of pretest and post-test with an increase in completeness percentage from 2.8% to 72%.
