Abstract

Pemahaman siswa mengenai larutan elektrolit dan non-elektrolit penting dalam kimia. Representasi makroskopis, sub-mikroskopik, dan simbolik diperlukan untuk memahami konsep ini. Namun, di MAN 2 Jombang belum ada analisis kemampuan multipel representasi siswa pada materi tersebut. Analisis tersebut diperlukan sebagai evaluasi untuk perbaikan pembelajaran ke depan. Tujuan dari penelitian ini meliputi: 1) mendeskripsikan perbedaan kemampuan multipel representasi siswa laki-laki dan perempuan. 2) mengetahui adanya signifikansi pada perbedaan kemampuan multipel representasi antara siswa laki-laki dan perempuan. Penelitian ini menggunakan pendekatan ex-post facto dengan jenis penelitian kausal komparatif. Teknik pengumpulan data menggunakan metode tes. Instrumen yang digunakan pada penelitian ini berjumlah 10 soal berupa pilihan ganda beralasan yang telah divalidasi ahli dan uji empiris serta terintegrasi pada kerangka kerja Definition, Algorithmic, Conceptual (DAC). Teknik analisis data yang digunakan pada penelitian ini adalah analisis statistik deskriptif dan statistik inferensial. Hasil penelitian ini menunjukkan bahwa 1) Terdapat perbedaan nilai rata-rata siswa laki-laki dan perempuan pada setiap indikator. 2) hasil analisis uji T Independet didapatkan nilai sig = 0,868 0,05 yang berarti bahwa tidak ada perbedaan yang signifikan antara kemampuan multipel representasi siswa laki-laki dan perempuan. Dengan demikian, perlu adanya peningkatan kemampuan multipel representasi siswa dan guru perlu memberikan perlakuan yang berbeda pada siswa sesuai dengan potensi yang dimiliki siswa.

Abstract

Acid-base material should ideally be evaluated holistically through the triplet of macroscopic, submicroscopic, and symbolic representations. However, the assessments conducted so far have primarily not evaluated the ability to understand submicroscopic representations and still focus on macroscopic and symbolic representations. Therefore, this research aims to develop an instrument for assessing submicroscopic understanding of acid-base material and analyze its feasibility. The research method used is the 4D model development, carried out up to the develop stage. The results of the content validation by expert validators yielded an average score of 91.2%, which falls into the very valid category. The empirical test results on 116 chemistry teachers and prospective chemistry teachers showed that all items on the instrument were valid with a reliability of 0.60, which falls into the reliable category. Moreover, the instrument has varying levels of difficulty index and discrimination power. The test items' character in the instrument assesses understanding of submicroscopic representations of acid-base concepts such as solution properties, acid strength, acid constant, pH, and degree of dissociation. The recommendation for further research is the need to develop and apply submicroscopic understanding questions in other chemistry topics as a reinforcement in the assessment and evaluation process of chemistry learning.
