Problem-Based Learning about Error Detection and Correction in Locus Problems with the Aid of GeoGebra Software

Problem-based learning puts students in situations that suggest problems without providing instructions and available knowledge. Therefore, when using problem-based learning, students need to be flexible, self-disciplined, active and self-occupied with knowledge and turn the knowledge the teacher intends to impart into their knowledge. For locus problems, learners often make mistakes in predicting results. GeoGebra software has been brought into teaching and has been a great help for students in the process of detecting and correcting mistakes in locus problems. Our article will analyze the views on problem-based learning and the scientific basis and provide a teaching process to detect and correct mistakes in locus problems with the help of GeoGebra software. In addition, we designed a teaching example that explicitly illustrates the above process. We found that students were more interested and excited.
