### Teachers' Comments About Their Experience of Teaching with a Real-Time Gaze
The integration process was relatively smooth, which I attribute to several factors, such as the ease of use of the technology and the comprehensive support provided by the manufacturers. One of the main considerations for successfully implementing this technique in the classroom, especially with younger elementary school students, is keeping their attention. Children often have difficulty focusing on a specific visual field for extended periods, which is crucial for effective eye tracking. Therefore, I consider it important that lessons incorporating eye tracking are visually appealing, well-organized, interactive, and offer varied stimuli. This approach helps keep students engaged and prevents them from feeling fatigued. It is also essential to ensure that sessions have an appropriate duration to maintain their comfort and interest. Additionally, it is fundamental to personalize the content to meet individual learning needs while respecting students' privacy. On the other hand, certain characteristics should be avoided during this type of lesson, such as the possibility of overwhelming students with excessive visual stimuli, which can become counterproductive. There must be a balance between the visual information presented and the student's ability to process it effectively. Adapting to the individual needs of students without stigmatizing them is essential, as is ensuring the ethical implementation of the technology and prioritizing their well-being. During the implementation, some unexpected challenges arose. For example, the type of glasses some students wore interfered with the calibration of the eye-tracking equipment. Additionally, factors such as students' height and individual eye characteristics posed calibration difficulties. However, after several attempts and adjustments to the equipment, students' postures, and seating arrangements, these issues were resolved, and the lesson proceeded smoothly. Overall, the technology provided clear insights into whether students were paying attention and understanding the instructions given throughout the lesson. This real-time feedback was very beneficial for quickly adjusting my teaching methods and better meeting students' needs. It allowed me to identify more clearly when a student was confused about a concept or section of the lesson. For example, in a coding lesson, I could see where a student struggled with a specific block of code, allowing me to provide targeted assistance. I do not foresee major disadvantages in using eye tracking in my classes. The potential for any negative impact seems more related to the teacher's correct application of the technology and the design of the lesson itself. Ensuring that the equipment is used appropriately and that lessons are structured to make the most of this technology is crucial. I prefer eye-tracking technology in specific situations rather than in all lessons. In my view, the most valuable application is understanding the difficulties faced by students with academic problems. For example, if a student consistently performs poorly, eye tracking can help determine if their problems are related to attention and concentration. This insight could inform adjustments in my teaching approach to better capture their attention and improve their understanding of the material. Observing students using the technology revealed some interesting characteristics. They were visibly attentive to the information presented and seemed comfortable and enthusiastic about participating in the new experience. This positive response suggests that integrating innovative technologies such as this can increase engagement and interest in the classroom.
