Educator and consultant Monica Burns advises teachers on tech use in the classroom. Here she offers descriptions and reviews of a number of apps she finds useful, such as an app called “pick a student” that chooses a student to call on in class; “Groovy Grader” automatically provides the percentage grade by inputting the number of questions on a quiz and “DocScan HD” allows you to “snap a picture of a meeting agenda, handouts from a professional development” and turn these into PDF and JPG files.
