The Victorian Curriculum and Assessment Authority (VCAA) has made a significant move to address the concerns surrounding the use of advanced model calculators in VCE maths exams. By banning the use of specific formulations and features on these calculators, the VCAA aims to level the playing field for all students and ensure a fair assessment of their mathematical skills. This decision, while a step in the right direction, has sparked debates among experts and educators about the effectiveness of the measures and the broader implications for education.
In my opinion, the VCAA's decision to restrict the use of user-defined functions (UDFs) on Computer Algebra System (CAS) calculators is a necessary and long-overdue move. The advanced features of these calculators, such as programming shortcuts and step-by-step procedures, have long been a source of concern for educators and students alike. As Greg Ashman, a deputy principal and maths teacher, aptly puts it, these calculators are 'desperately unfair' as they provide an unfair advantage to students who have the coding skills or access to programs that can enhance their capabilities.
What makes this particularly fascinating is the tension between technological advancement and traditional educational values. On one hand, CAS calculators offer the potential to enhance learning by providing immediate feedback and support for complex calculations. On the other hand, they risk undermining the development of core mathematical skills and critical thinking abilities. The VCAA's decision to restrict the use of UDFs is an attempt to strike a balance between these two forces, but it raises important questions about the role of technology in education.
From my perspective, the VCAA's approach is a pragmatic one, recognizing the need to adapt to technological advancements while maintaining the integrity of the assessment process. However, it is not without its flaws. As Professor Burkard Polster points out, monitoring students' use of these calculators in exams is a challenging task, and the changes don't go far enough to ensure a level playing field. The question remains: how can we effectively regulate the use of technology in education without stifling innovation and creativity?
One thing that immediately stands out is the need for a more holistic approach to education that goes beyond the use of technology. While CAS calculators can provide valuable support for learning, they should not be seen as a replacement for critical thinking and problem-solving skills. Instead, they should be used as a tool to enhance learning and support students' development of these essential skills. This raises a deeper question: how can we best prepare students for the challenges and opportunities of the future, both in terms of technology and critical thinking?
A detail that I find especially interesting is the impact of this decision on students who go on to study STEM fields in university. As Polster notes, the lack of a fundamental understanding of mathematics can be a significant barrier for these students. This highlights the need for a more integrated approach to education that bridges the gap between secondary and tertiary education. What this really suggests is the importance of a well-rounded education that fosters critical thinking, problem-solving, and a deep understanding of mathematical concepts.
In conclusion, the VCAA's decision to restrict the use of UDFs on CAS calculators is a step in the right direction, but it is not a panacea for the challenges of modern education. As we navigate the complexities of technology and assessment, it is essential to maintain a critical perspective and a commitment to fostering a well-rounded, holistic education. Personally, I believe that the future of education lies in finding a balance between technological innovation and traditional values, and this decision is a small but important step in that direction.
