I must say that I'm thoroughly impressed with the Freudenthal Institute for Science and Mathematics Education. Their website, fi.uu.nl, offers a wealth of resources for educators and students. I particularly appreciate the attention to detail and the user-friendly interface. The organization and presentation of materials are top-notch. I'm grateful for the valuable resources they provide and will continue to utilize them in my teaching endeavors.
