ANALISIS KEMAMPUAN MULTIREPRESENTASI SISWA PADA MATERI KESETIMBANGAN KIMIA DI MASA PANDEMI COVID-19

ANALYSIS OF STUDENTS’ MULTIREPRESENTATION SKILLS ON CHEMICAL EQUILIBRIUM DURING THE COVID-19 PANDEMIC

Penelitian ini bertujuan untuk mengetahui kemampuan multirepresentasi yang terdiri dari representasi makroskopik, representasi submikroskopik, dan representasi simbolik siswa kelas XI IPA SMA Negeri 1 Krian tahun ajaran 2020/2021 pada materi kesetimbangan kimia di masa pandemi covid-19. Jenis penelitian ini merupakan penelitian deskriptif. Metode yang digunakan dalam penelitian yaitu mix methode dengan tipe embedded. Subjek penelitian ini adalah siswa kelas XI IPA yang berjumlah 31 siswa. Teknik pengumpulan data berupa pengukuran hasil tes tulis dan hasil wawancara bebas terpimpin. Instrumen penelitian berupa 15 soal tes uraian yang memiliki validitas 0.5 hingga 0.8, reliabilitas 0.934, daya pembeda 0.5 hingga 08, dan tingkat kesukaran 0.4 hingga 0.8. Berdasarkan hasil penelitian menunjukkan bahwa kemampuan multirepresentasi siswa pada materi kesetimbangan kimia di masa pandemi covid-19 yang dilakukan secara daring tergolong rendah dengan persentase rata-rata kemampuan representasi makroskopik, representasi submikroskopik, dan representasi simbolik siswa secara berturut-turut sebesar 35.01% dengan kategori kurang, 40.59% dengan kategori kurang, dan 50.55% dengan kategori cukup.

This study aims to determine the ability of multi-representation consisting of macroscopic representations, submicroscopic representations, and symbolic representations of XI IPA SMA Negeri 1 Krian academic year 2020/2021 on chemical equilibrium material during the Covid-19 pandemic. This type of research is a descriptive study. The method used in this research is the mix method with the type embedded. The subjects of this study were 31 students of XI IPA. Data collection techniques are measuring the results of written tests and the results of guided free interviews. The research instrument was 15 essay test questions with a validity of 0.5 to 0.8, reliability of 0.934, distinguishing power of 0.5 to 08, and difficulty level of 0.4 to 0.8. The research results show that the ability of students' multi-representation on chemical equilibrium material during the Covid-19 pandemic, which done online was low. The average percentage of macroscopic representation, submicroscopic representation, and symbolic representation of students is 35.01% with a low category, 40.59% in the less category, and 50.55% in enough category.
