Abstract
The teacher is the most important component in the teaching-learning process as well as the most significant influence at the school. The aim of the study was to evaluate the teachers’ performance and their effectiveness in the classroom setting by adhering to the determinant factors. The study was conducted last academic year, 2021–2022, during the outbreak of COVID-19 at randomly selected public secondary schools in Agusan del Sur, Philippines. The study has employed a quantitative research method with a descriptive correlational design. This study had a total population of 100 teacher-respondents from the five (5) chosen schools. Slovin's formula was used to calculate the sample size, which had a 0.05% error margin. A stratified random selection was utilized to distribute the respondents evenly throughout the teachers' areas. The researcher employed a descriptive-survey questionnaire to collect the data required for the said investigation, following the main purpose of the study to evaluate the teachers’ performance and their effectiveness in the classroom setting by adhering to the essential factors. The statistical tools that have been utilized in the study are descriptive and inferential statistics. The results of a correlational analysis had an associated probability of a p-value equal to 0.000, a value that was much lower than the alpha value of 0.05. As a result, the findings highlight the determinant factors that influence teaching performance and have a significant impact on teachers' performance. As a result, it is critical for every school to retain its qualified teaching staff.
