What It Is

21Things4.net is an educational technology resource and professional development program designed for K-12 education. It was first launched in 2008 and was created and continuously maintained through collaboration among instructional technology specialists in the U.S. state of Michigan. The site includes sections such as “21 Things 4 Educators,” “MiTechKids,” “21 Things 4 Students,” and “iPads in Action.” Its core goal is to help teachers, students, and education administrators use free tools for digital teaching and learning.

Core Content and Format

Its courses and resources are mainly designed around the ISTE Standards. For teachers, it offers 1- to 3-hour professional development modules that emphasize free tools/apps, pedagogy, learning objectives, and hands-on activities. It also provides ready-to-use “grab and go” training materials for instructional coaches. The K-5-focused MiTechKids section offers task-card lessons of 20 minutes or more, which can be searched by platform, content area, device, and other criteria. The grade 5-9 student courses are built around technology concepts and project-based tasks, including checklists, formative assessments, and the opportunity to earn badges and certificates. Teachers can also customize the resources for LMS platforms such as Google Classroom, Schoology, Moodle, and Canvas.

Pricing and Certification

The site repeatedly emphasizes the use of free tools and free resources, and there is no visible information about subscriptions, purchases, or paid courses. In terms of certification, 21 Things 4 Educators has held the ISTE Seal of Alignment since 2014. The student courses mention badges and certificates, but do not specify their formal recognition or external value.

Pros and Cons

The strengths of the project are its long history, clear institutional and expert collaboration background, alignment with ISTE standards, and resource granularity that makes it suitable for teachers to directly use in classroom activities or in-school training. It is especially friendly to instructional technology coaches because it provides “grab and go” materials. Its drawbacks are that the content is clearly oriented toward the U.S. K-12 system, the default language is English, and no Chinese support is visible. The site also does not explain user support, a learning progress system, or the value of its certificates, so it is somewhat limited as a fully fledged formal professional training product.

Who It’s For and Access in China

It is better suited to K-12 teachers with strong English skills, educational technology coaches, international school teachers, and teaching and research staff who want to build digital literacy courses with reference to ISTE standards. The review text does not provide information on access from mainland China, so this remains unknown.
