week of the semester. These meetings were to guide the students in the early stages of the project and before starting laboratory works. During the meetings students were encouraged to give their opinions to enhance critical thinking on environmental issues.
In the following academic years, i.e. 2008/2009, 2009/2010, and 2010/2011, the students were required to suggest their own topics on environmental issues. The aim for this approach was to encourage the students to be more proactive in conducting their own search for information from various sources. Another PBL projects that were given to the groups of students were to obtain information from various government and private agencies related to environmental protection and services such as the Department of Environment, Department of Irrigation and Drainage, Meteorological Department, the National Department of Solid Waste Management, etc. The aim of this task was to develop awareness among the students on various agencies related to the environment that they may come across in the future at their workplace.
