Pendekatan Onto-Semiotik Berbasis Problem Solving untuk Memperbaiki Pengetahuan Tanda “Sama Dengan” by Ahmad Hassan Nurdien, Mohammad Faizal Amir

“…Knowledge of concepts or symbols is important for elementary school students as the basis for understanding algebra at an advanced level. This study aimed to identify students' knowledge of the equal sign "=" through the application of an onto-semiotic approach based on problem-solving in elementary school students based on each level of knowledge in the concept of mathematical similarity. …”
