AppInventor.org was recently designated one of the Best Websites for Teaching and Learning, by the American Association of School Libraries (AASL). The award was announced at the American Library Association’s annual conference (press release).
AppInventor.org was developed at the University of San Francisco (USF) under the direction of Professor David Wolber and with the contributions of numerous USF students (see below). The site teaches beginners how to build apps with the drag-and-drop coding language, MIT App Inventor. The site reaches thousands of self-directed learners each month and provides a “Course-in-a-Box” for teachers of all levels.
AppInventor.org and this award are only possible because of the amazing App Inventor language and the amazing work of Hal Abelson and the MIT App Inventor team. Great work everyone!

A DTF printer, or direct-to-film printer, is a machine that prints designs directly onto PET film, which is then treated with hot melt powder and heat-pressed onto clothing or other materials. It offers fast printing speeds and consistent quality, is suitable for a variety of fabrics and surfaces, and does not require pre-treatment liquid, making it a popular choice in the field of garment printing.
Amazing to see AppInventor.org recognized by AASL as one of the best teaching websites 👏 Low-code tools like this really lower the barrier for students to experiment with real-world ideas—whether that’s building simple mobile apps or even creating control interfaces for hardware projects like a wall printer. This kind of accessible, visual programming is exactly what sparks the next generation of makers and developers.
