Individualized instruction, with grouping based on proficiency, can address the difficulties faced by learners in classrooms with mixed ability levels. However, standard, lecture-based instructional approaches will simply not support individualized learning. Alternatively, online or blended learning may take advantage of virtual learning environments (VLE) designed for achieving individualization by creating a learner-centered and interactive environment for efficient learning (Karagiannidis, Sampson, & Cardinali, 2001; Shang, Shi, & Chen, 2001). These online environments overcome the physical and time constraints of a typical classroom, offering learners an individualized and adaptive learning experience (Meurant, 2010; Shute & Towle, 2003).
