The social interactions, way of learning, and approach to learning of secondary school students are influenced by many personality traits. Among these personality traits, the most common are introverted and extroverted personality types. In this research, we hope to learn about the differences in introverted and extroverted personality types in Boys and Girls in Secondary Schools. The researchers will conduct a quantitative study using a Standardized Personality Inventory to collect a random sample of the students. Additionally, It is believed that this study will lead to the development of guidelines for educators and policymakers on how to develop effective instructional strategies for all varieties of students with differing personality traits, as well as maximize the potential for Total Student Development.
