Artikel ini merupakan hasil penelitian terkait kemampuan self efficacy matematis siswa SMP pada dua kelas. Penelitian ini bertujuan untuk mengetahui interaksi antara penerapan pembelajaran worksheet berbasis softwere Geogebra terhadap kemampuan self efficacy matematis siswa ditinjau kemampuan awal matematis (KAM) siswa. Melalui metode quasi eksperimen dengan desain pre test-post test, penelitian ini melibatkan 72 siswa SMP. Hasil penelitian menunjukkan adanya perbedaan peningkatan rata-rata kemampuan self efficacy matematis ditinjau dari kemampuan awal matematis (KAM). Hasil penelitian juga menunjukkan adanya peranan kemampuan self efficacy matematis antara kelas konvensional dan kelas eksperimen dari kemampuan awal siswa. Hal ini menunjukan bahwa peranan pembelajaran matematika berbasis softwere Geogebra mampu meningkatkan self efficacy siswa dibandingkan pembelajaran tanpa menggunakan softwere Geogebra. AbstractThis article is the result of research related to the mathematical self efficacy of junior high school students in two classes. This study aims to determine the interaction between the application of Geogebra softwares-based worksheet learning on students 'mathematical self efficacy abilities in terms of students' initial mathematical abilities. Through the quasi-experimental method with the pre-post-test design, this study involved 72 middle school students. The results showed a difference in the average increase in mathematical self efficacy abilities in terms of initial mathematical abilities (KAM). The results of the study also showed the role of mathematical self efficacy abilities between conventional classes and experimental classes from students' initial abilities. This shows that the role of Geogebra software-based mathematics learning can improve students' self-efficacy compared to learning without using Geogebra software.

This study aims to analyze the critical thinking skills of junior high school students on Pythagoras material. Subjects in this study are students of class VIII-F in SMP Negeri 1 Ngamprah with the number of students 37 people. The method used in this research is qualitative descriptive. This type is chosen because it aims to describe the skills of students in solving problems of mathematical critical thinking independently. The research phase is divided into three, namely planning, implementation, and reporting. The technique of collecting data in the form of test. Data analysis techniques based on indicators of mathematical critical thinking skills that has been determined by researchers include: (1) identifying the concepts used in problem solving, (2) formulating an action (strategy, tactics, or approach) in solving problems, (3) providing arguments or reasons for answering and solving problems, and (4) evaluating evidence or decisions taken in solving the problem. The results obtained quantitatively show that the level of mathematical critical thinking skills of students in SMP Negeri 1 Ngamprah in solving the problems on Pythagoras material still falls into the low category. The evidence from the percentage of each indicator with the highest rate of only 61%. Some factors influence the level of students critical thinking skills, including the preparation of incomplete and appropriate strategies, provide arguments without showing the truth, and the students' accuracy in working on the questions.

Penelitian ini dilatarbelakangi oleh rendahnya HOTS siswa pada materi trigonometri pada siswa SMA di salah satu sekolah swasta di Cimahi, siswa merasa kesulitan dalam memahami materi trigonometri dikarenakan bahan ajar yang digunakan belum memfasilitasi proses berpikir tingkat tinggi siswa, sehingga diperlukan pengembangan bahan ajar yang berbasis inkuiri agar HOTS siswa semakin meningkat. Tujuan dari peneitian ini adalah untuk mengembangkan LKS berbasis Inkuiri pada materi trigonometri. Metode penelitian ini adalah metode pengembangan dengan desain 4D yaitu pendefinisian (define), perancangan (design), pengembangan (develope), dan penyebaran (desiminate), namun karena keterbatasan waktu penelitian ini tidak sampai pada tahap penyebaran. Subjek dari penelitian ini yaitu siswa kelas X di salah satu SMA swasta di Kota Cimahi sebanyak 32 siswa. Teknik pengumpulan data pada penelitian ini menggunakan instrumen tes HOTS untuk mengukur efektivitas bahan ajar serta lembar validasi untuk mengukur validitas bahan ajar. Berdasarkan hasil analisis data dapat disimpulkan bahwa bahan ajar berupa LKS yang dikembangkan dinyatakan valid dengan rata-rata nilai validitas dari validator ahli sebesar 3,4 serta efektivitas dari peningkatan kemampuan HOTS sebesar 35,3%. Adapun implikasi dari penelitian ini yaitu guru dapat menggunakan LKS berbasis inkuiri ini sebagai bahan ajar pada materi trigonometri agar kemampua HOTS siswa meningkat.
