Penelitian bertujuan mengidentifikasi kesesuaian komponen concept maps dan argumentasi pada materi pencemaran lingkungan di era covid-19. Penelitian merupakan penelitian deskriptif kuantitatif dengan metode survei. Populasi penelitian adalah siswa kelas X MIPA SMA Negeri 1 Karanganyar. Sampel penelitian berjumlah 72 siswa. Pengambilan sampel menggunakan teknik clustered random sampling. Instrumen penelitian terdiri dari expert concept map dan soal argumentasi. Validasi instrumen penelitian berupa expert concept maps dilakukan oleh ahli materi untuk menilai kelayakan konten sedangkan validasi instrument soal argumentasi menggunakan model rasch meliputi validitas konstruk dan validitas konten. Validitas konstruk soal argumentasi tergolong baik  (raw explained by measure: 43.0%). Validitas konten per item soal menunjukkan 2 soal yakni soal nomor 7 dan 8 tidak valid, namun soal tetap digunakan karena soal memuat komponen yang menjadi satu kesatuan dari komponen argumentasi. Teknik pengumpulan data concept maps dan argumentasi siswa yaitu teknik tes yang diberikan pada akhir pembelajaran menggunakan google form. Concept maps hasil konstruksi siswa dijustifikasi dan dinilai berdasarkan expert concept maps dengan sistem penskoran berdasarkan <!--[if supportFields]>ADDIN CSL_CITATION {"citationItems":[{"id":"ITEM-1","itemData":{"ISBN":"9780521265072","author":[{"dropping-particle":"","family":"Novak, J.

Uji Mann Whitney dilakukan untuk menguji signifikansi perbedaan pola distribusi komponen concept maps dan argumentasi sehingga teridentifikasi ada atau tidaknya kesesuaian antar komponen yang merupakan kesimpulan hasil penelitian. Hasil penelitian menunjukkan nilai signifikansi semua komponen yang dipasangkan sama dengan 0.00 artinya terdapat perbedaan yang signifikan antara komponen concept maps dan argumentasi.
