From lectures to field study: a master course’s subject on biological approach for water quality monitoring
During a Master Course program in Environmental Pollution and Prevention at Faculty of Environmental Sciences, National University of Laos (NUOL), a subject “Biological approach for water quality monitoring” is an important part of the course which is taught by Asso. Prof. Dr. Chanda Vongsombath, Dean of the faculty. Beside the lectures. Attending the course, there were 8 master students who practiced the field data collection with learnt methodology and water quality assessment in the subject. This also a part of the subject in which the problem-based learning (PBL) teaching methodology was applied. In this field data collection, the student learnt how to collect macro invertebrate in the lotic ecosystem which could be used as biological indicators for water quality. The field study was done at the Nam Nguem River located at Toulakham District, Vientiane Province on 21 February 2023.
