“…The majority of the articles (65.1%) generated results related to the college students. A wide range of aspects was considered, for example, Andreoletti and Howard [46], Augustin and Freshman [33], and Lokon et al [29] concentrated on the increase of students’ positive perceptions; Kohlbry and Daugherty [35] analyzed the development of their cultural awareness, knowledge, and skills; Chen [46], D’Abundo et al [27], and Giné-Garriga et al [48] observed students’ practical experience; Neill et al [43] and Neal et al [49] examined the improvement of students’ perception of professional competence; and, finally, Gazsi and Oriel [34] investigated the integration of course content through applied SL. For the rest of the sample, only four papers (9.3%) focused on aspects such as older adults’ perceptions or changes, experiences, learning, thoughts, feelings, or relationships [4,14,36,44].…”
