Bender, a former junior high school teacher who consults and writes about practical instructional tactics with an emphasis on response to intervention and differentiated instruction, and Waller, who teaches underprivileged children in a rural school and provides workshops for educators on technology for reading and differentiated instruction, identify 20 technology tools that teachers can use in the classroom, especially for those that have been reluctant to embrace it. The tools represent the first steps in technology-based teaching that can be implemented by individual teachers, and consist of essential tools (web access, laptops, mobile devices, webquests, blogs, and wikis); tools for student engagement and empowerment (cloud computing, the flipped classroom and the Khan Academy, Wiffiti, Jing, gaming, alternative reality gaming, virtual world instruction, and Diigo); tools for student creation and collaboration (Glogs, podcasts, Scribd, Comic Life, Google Apps, Vokis, avatars, animation, vlogs, and Animoto); and tools for social learning and networking (Facebook and Twitter). For each, they explain what teachers need to know, how to get started, and differentiation, with some sample lesson plans and information on professional development.
