The study observed on how COVID-19 disturbed the universe, its detrimental factors to detriment the constituents in particular to educational endeavor, the outcomes to teachers and to the learners. Yet, on the contrary this is also an opportune to extend teaching stratification whom a concluding scenarios that sometimes attending classes in the classrooms were insignificant not unless for formative assessment, 21st pedagogues more probably applicable whereby lectures can be done thru social media (blogs, group chats, emails). The study conveyed also that research-output-based teaching methods are more desirable as if students would be taught on how to be a writer and a researcher. However, this COVID-19 reciprocally demean traditional maneuvers hence attendance literally are not necessary, this is a resolution of vanishing the old methods of teaching but on the other hand modular concept has led to resolve the issue. This COVID-19 definitely an uprising of a new beginning onward to educational teaching stratification but subsequently this is also threatening students of which their only avenue to attain the learning process is going to internet café where they are exposed, and prohibited for safety precautions. This disease skeptically made excuses for those who were non-focus, malingered individual either to their studies or duty, this even defying one’s authority for a reason of security, a banishment of those known with infected disease, and economically the Local Government Unit (LGU) were suppressive. 

Lake Mainit is one of the key biodiversity areas in the country, its watershed area is a habitat of endemic and native plant species but is now threatened due to anthropogenic activities such as mining, kaingin and expansion of agriculture. This study assessed the diversity and community structure of plants in the lowland and upland of the two selected areas (Cantugas and Jabonga) of Lake Mainit watershed through a transect and quadrat method. A total of 321 floral species were identified distributed into 85 families. The taxonomically well distributed families were Arecaceae, Moraceae and Fabaceae with 18, 17 and 14 species respectively and most species were trees and shrubs (187 species). The highest species diversity, richness and abundance was observed in the lowland of Jabonga while the highest dominance was observed in the upland of Catugas. The floral species of Lake Mainit watershed are threatened by anthropogenic activities especially expansion of agriculture and tree felling for infrastructure developments regardless of their environmental roles and inherent benefits. Therefore, sustainable conservation efforts should be geared towards ensuring their continuous existence in order to maintain environmental integrity.

The purpose of the study showcases the Learner self-evaluation on performance rating as part of giving final grade by uncovering his personal experiences in his education about Linear Algebra at the UPOU. The study adopts and modify the theory of Rappe & Hayman (1996) on self-evaluation as the basis for rating performance, and used the conceptual framework introduced by Mahmood, Othman & Yusof (2012) in gathering data. Then, Grading Rubrics served as the basis for self-evaluation in giving final grade by proficiency indicated in the graphics presentation. In lieu to this study asked questions were hypothetically satisfied which revealed that the Learner compared his impressions about the subject prior and after he took the course; uncovered his difficulties and the causes in linear algebra; emphasized the real significance of the course by enumerating the techniques and skills he acquires which can be helpful on his future career; and described his participation in synchronous meetings with the asynchronous methods, reflected his understanding about the modules, homework, attendance to synchronous meetings, and relating the most helpful aspects about the course; provided self-evaluation on his performance rating from 0 to 100, with 100 being excellent and 60 being average, and justify his self-evaluation performance rating. Thus, based on the Grading rubrics his homework proficiency has accumulated with a total score of 329 over 400 with the equivalent percentage of 82.25% in Homework 1–6 which means within the range from 75–90% this result contemplated that Learner’s proficiency describes that his homework provides a complete, correct, rigorous proof or solution but is not that written well. Comprises also were an outcomes that from monitoring assessment on learning and teaching improvement, it has been recognized by a character that the learner has almost 100% in attendance to the synchronize meetings and participated, communicated in some instance important matters via emails, portal messenger; with complete compliance and perfect submission of homework and obtained a recognizable score by proficiency having 1 item with 60–80%, 1 item with 90–99%, and 9 items with 100%, and finally met a maximum rating score of 100% for final (summative) homework. Systematically, based on results from this study, the Learner’s performance rating probably can be computed anytime in the following criterion: Proficiency in Homework + Characteristic in the Learning Process + Monitoring Assessment on learning and teaching improvement + Learner's Principles in Linear Algebra (rated by the professor) of which the ultimate results for the Learner’s final grade, should be coming from the professor’s personal records and evaluation. Thus, the teacher’s objective criterion on giving final grade is the ultimate verdict.
