This study aimed to generate an analysis of the awareness and practices in the ecology of Graduate school students.

This study mines the paragraphs that form a document of 54 graduate school students in the research methodology class. These students as respondents are private and public school teachers. The documents are dissected and grouped into: a) number of words is 12407; b) lexical density is 15.1769; c) number of sentences is 841; and d) number of syllables is 20283. The study found out that retooling teachers on ecological practices are necessary. The teachers do not practice all of the 5Rs. The common ecological practices of the teachers are recycle, reduce and reuse. Teachers are aware of the waste and garbage problems but have decreasing attention in protecting and saving the environment. An instructional material can be developed using formed word cloud from the prominent words used by the respondents in their statements on ecological awareness and practices. The study recommends that the teachers should undergo intensive training, orientation, and information drive on the practice of 5R.
