One innovative, computer-mediated assessment I have implemented in my mathematics classes is the use of online mathematics simulations and interactive tools, such as GeoGebra. GeoGebra is a dynamic mathematics software that allows students to visualize and manipulate mathematical concepts in real time. In my classes, I use this tool to assess students' understanding of geometric shapes, algebraic functions, and calculus concepts. For example, I can create tasks where students explore the properties of geometric figures by dragging points to see how changes affect angles and side lengths, or manipulate algebraic equations to observe how graphs change.

The strength of using GeoGebra as an assessment tool lies in its ability to engage students actively and visually. It caters to different learning styles, as visual learners can see concepts in action while kinesthetic learners can interact directly with the material. Additionally, the immediate feedback provided by the software allows students to learn from their mistakes and encourages a growth mindset. They can experiment without the fear of failure, which promotes deeper understanding and retention of mathematical concepts.

However, there are challenges associated with this type of assessment. Not all students may have access to reliable internet and devices, leading to inequalities in participation. Furthermore, while GeoGebra provides immediate feedback, interpreting that feedback effectively requires guidance from teachers. Some students may struggle with self-directed learning in a digital environment and might not perform as well without direct teacher support. Despite these challenges, I have found that incorporating computer-mediated assessments like GeoGebra enriches the learning experience, making mathematics more interactive and enjoyable for my students.
