“…Concept mapping was developed by researchers in Cornell University for representing conceptual knowledge structures (Novak & Gowin, 1984; Novak & Musonda, 1991). Several qualitative and quantitative studies have shown that with the help of concept maps, meaningful learning can be effectively promoted, such that positive effects can act upon students (Horton et al , 1993; Trent, Pernell, Mungai & Chimedza, 1998). Furthermore, concept maps can also be a visualised cognitive tool supported by computer systems (Anderson‐Inman & Ditson, 1999; Fischer, Bruhn, Grasel & Mandl, 2002).…”
