Abstrak Rendahnya kemampuan pemecahan masalah matematis siswa SMP terkonfirmasi melalui studi pendahuluan, dengan rata-rata capaian hanya 33,75% berdasarkan indikator Polya, akibat pembelajaran yang masih bersifat prosedural, LKPD konvensional tanpa konteks nyata, dan keterbatasan fasilitas teknologi di sekolah. Penelitian ini bertujuan mengembangkan Lembar Kerja Peserta Didik (LKPD) berbasis MathTrails pada materi statistika ukuran pemusatan dan penyebaran data sebagai upaya meningkatkan kemampuan pemecahan masalah matematis siswa melalui aktivitas penelusuran kontekstual di lingkungan sekolah. Penelitian menggunakan model pengembangan 4D (Define, Design, Develop, Disseminate) yang dibatasi hingga tahap Develop. LKPD dirancang dengan 10 komponen aktivitas yang memetakan keempat indikator pemecahan masalah Polya ke dalam kegiatan penelusuran nyata melalui 10 titik pos di lingkungan sekolah. Kelayakan produk dinilai oleh tiga validator ahli pada aspek kelayakan isi, penyajian, kebahasaan, kesesuaian model, dan tampilan, dengan hasil rata-rata persentase sebesar 94,0% (kategori sangat valid), serta dikonfirmasi konsisten melalui Cochran's Q Test (Q = 6,000; Sig. = 0,050). Uji kepraktisan pada sembilan siswa melalui angket respons menghasilkan rata-rata persentase 85,88% pada kategori sangat praktis, mencakup aspek kemudahan penggunaan, kejelasan petunjuk dan isi, kemenarikan tampilan, serta manfaat LKPD. Temuan ini menunjukkan bahwa LKPD berbasis MathTrails yang dikembangkan valid dan praktis, sehingga layak digunakan dalam pembelajaran statistika tanpa membutuhkan teknologi canggih, cukup dengan memanfaatkan lingkungan sekitar sebagai sumber belajar yang autentik dan bermakna.   Abstract The low mathematical problem-solving ability of junior high school students was confirmed through a preliminary study, with an average achievement of only 33.75% based on Polya's indicators, attributed to procedural-based instruction, conventional student worksheets lacking real-world context, and limited technological facilities in schools. This study aims to develop a MathTrails-based Student Worksheet on statistics topics covering measures of central tendency and data dispersion, as an effort to enhance students' mathematical problem-solving skills through contextual trail activities within the school environment. The study employed the 4D development model (Define, Design, Develop, and Disseminate), limited to the Develop stage. The student worksheet was designed with 10 activity components mapping all four of Polya's problem-solving indicators into real trail activities across 10 checkpoint stations within the school environment. Product validity was assessed by three expert validators across aspects of content feasibility, presentation, language, model appropriateness, and visual design, yielding an average percentage of 94.0% (categorized as highly valid), further confirmed as consistent through Cochran's Q Test (Q = 6.000; Sig. = 0.050). Practicality testing involving nine students via a response questionnaire produced an average percentage of 85.88%, categorized as highly practical, encompassing aspects of ease of use, clarity of instructions and content, visual appeal, and the benefits of the student worksheet. These findings indicate that the developed MathTrails-based Student Worksheet is both valid and practical, making it suitable for use in statistics learning without requiring advanced technology, relying instead on the surrounding environment as an authentic and meaningful learning resource.
