The acquisition of handwriting as a competence has been important for centuries. In primary schools this technique is exercised as a foundation for the performance in other cultural techniques like language writing and even calculus. Therefore, it has been beneficial to make sure children acquire basic competences in handwriting. This has not changed much, although the time devoted to perfection of the technique has been reduced over generations. We still have some memories of people who have made the handwriting or the pencils used a case of distinction. At the enlightenment period a lot of authors drafted their thoughts and manuscripts in handwriting and our museums or biographies are proud to show off handwriting of authors, artists or composers. In some of those we are able to retrieve the thought process behind the writing. The editing, crossing out, adding sentences or correcting words are traces to dive deeper into these creative processes.
Currently, we are less sure, whether in the age of AI we should still rely much on this old technique of handwriting. If we just treat it as one of many competences to be or become creative yourself, we are on the right track. The PISA studies by OECD include problem-solving as a crucial competence. Handwriting or drafting first steps of a solution might still be useful. A handwritten sketch of a solution might guide the elaboration of the more encompassing solution.
Another interesting feature of handwriting is the cross-cultural element of it. We feel easily compassion for a handwritten document. The psychomotor competence of handwriting is fascinating across continents. It has distinguished us from other species as well. The evolutionary steps are important elements of a learning process. Nostalgic feelings about handwriting do not help anybody, but children are well-advised to still keep an eye on their handwriting competence as part of or first step in problem solving, even if it is just to formulate the question they are interested in.
