“…This definition explicitly excludes (a) in‐school guided study; (b) home study courses delivered through the mail, television, audio or videocassette, or the internet; and (c) extracurricular activities such as sports and participation in clubs (Cooper et al, 2006 ). With the development of technology, web‐based homework has become more popular among teachers, with online platforms such as Blackboard, WebCT ( www.webct.com ), Homework Service ( https://hw.utexas.edu/bur/overview.html ), WebWorK, Study Island, and PowerSchool (Mendicino et al, 2009 ), as these allow students to do their homework online, and teachers to give feedback to students immediately (Callahan, 2016 ; Lucas, 2012 ; Mendicino et al, 2009 ). Therefore, in this systematic review, homework also includes online tasks performed outside the school.…”
