Using tools for calculation
INTRODUCTION
It is important to develop numeracy skills around calculations, but it is good to realize that using calculational tools offer significant benefits in enhancing efficiency, understanding, and application of mathematical concepts, making them valuable aids in numeracy development. Balancing the use of calculational tools with the development of fundamental understanding the concepts underlying the computational aspects of numeracy is crucial. It’s important to ensure that using these tools enhance learning without replacing the fundamental understanding and skills that are essential in numeracy development. That formal understanding not automatically indicate that the algorithms for bigger calculations are performed with pen-and-paper (see Hoogland, 2023).
KEY ISSUES
The use of calculational tools, such as calculators and computer software, in numeracy development offers several positive opportunities:
- Enhanced Efficiency: Calculational tools significantly speed up the process of performing complex calculations, allowing individuals to complete mathematical tasks more quickly and efficiently. This is especially useful in professional and academic settings where time is a critical factor.
- Access to Advanced Mathematics: These tools make advanced mathematical operations accessible to a wider audience. They enable individuals to explore and understand complex concepts in mathematics, physics, engineering, and other fields that would be difficult or impossible to calculate manually.
- Reducing Cognitive Load: By taking care of routine calculations, these tools can reduce cognitive load, allowing individuals to focus on understanding and solving more complex aspects of a problem. This can enhance conceptual understanding and problem-solving skills.
- Error Checking: Calculational tools can be used to verify the accuracy of manual calculations. This dual approach reinforces learning and understanding, as individuals can compare their manual solutions with those provided by the tool.
- Visual Learning and Representation: Many modern calculational tools offer graphical representations of mathematical concepts, which can be particularly beneficial for visual learners. Graphing calculators and software, for instance, can help in understanding functions, geometric shapes, and other concepts through visual means.
- Real-world Application and Relevance: These tools can demonstrate the real-world application of mathematical concepts. For instance, financial calculators can help individuals understand concepts in economics or personal finance, making math more relevant and interesting.
- Inclusive Education: For students with certain disabilities, calculational tools can be invaluable. They enable these students to participate in math classes and understand concepts that might otherwise be inaccessible to them.
- Encouraging Exploration and Creativity: With the burden of complex calculations handled by tools, individuals can focus more on exploring different approaches to problem-solving, fostering creativity and innovation in mathematical thinking.
- Building Confidence: For some, particularly those who find mathematics challenging, the use of calculational tools can help build confidence. Knowing that they can rely on these tools for assistance can make them more open to engaging with mathematical tasks.
- Preparation for Future Technologies: In a world where technology is increasingly integral, familiarity with calculational tools prepares individuals for future academic and professional environments where such tools are commonplace.

Issues around the everyday use of tools
Discuss the flowing issues around synchronous online learning environments
The issues below are mentioned a lot in media to warn for the use of everyday tools like a calculator. They are from another paradigm on tool use than the key issues mentioned at the start of this modules. Discuss them and discuss ideas how to counteract those threats with relevant educational approaches.
- Dependency: Over-reliance on calculational tools can lead to a lack of fundamental skills. Individuals might become dependent on these tools for basic calculations, hindering their ability to perform mental math or understand the underlying concepts.
- Understanding Concepts: While calculational tools provide quick answers, they may impede the deep understanding of mathematical concepts. The process of manually solving problems helps in grasping why and how certain mathematical principles work, which can be bypassed with the use of these tools.
- Error Recognition: Without a solid understanding of the underlying mathematics, individuals may find it difficult to recognize when a calculational tool has provided an incorrect or implausible result. This is particularly important in situations where estimation or checking is necessary.
- Development of Mental Math Skills: Mental math skills are important for everyday tasks and quick decision-making. Relying too much on calculational tools can weaken these skills, making it more difficult to perform simple calculations in situations where tools are not available.
- Educational Disparities: Access to calculational tools can vary widely, leading to disparities in education. Students without access to these tools may find themselves at a disadvantage, while those who rely on them heavily may not develop sufficient manual calculation skills.
- Problem-Solving Skills: The process of working through a mathematical problem manually can develop critical thinking and problem-solving skills. Overuse of calculational tools might limit the development of these skills, as the tool often bypasses the problem-solving process.
- Technological Limitations and Misuse: Calculational tools are only as good as their programming and the user’s ability to use them correctly. Misunderstandings about how to input data or interpret results can lead to errors. Additionally, these tools might not be suitable for all types of mathematical problems.
- Assessment Challenges: In educational settings, it can be challenging to assess a student’s true understanding of mathematics when calculational tools are used. There’s a risk that assessments might evaluate a student’s ability to use a tool rather than their understanding of math.
