The current research examined the effects of teachers and classrooms environment on girls' learning skills in girls' high schools. The main objective of the study was to analyze the classroom as a key academic and learning site in which the nature of interaction between teachers and students and among peers have a strong impact on students' learning skills. The study covers 271 girl students from four high schools (two government and two private schools) from district Gujrat, Pakistan. A proportionate random sampling technique was employed to draw a sample from the population. A quantitative cross-sectional survey method was conducted. The measurement tool consisted of eight different measurements of teacher, classroom, and learning skills respectively. The study findings reveal that the classroom environment has been positively associated with the learning skills of the girl students. We experiment with different formulations of the dependent and independent variables, taking full advantage of our data and additional analyses using Structural Equation Modeling (SEM), allowed us to better ascertain and quantify the causal pathways in the relationship between classroom and girls' learning skills in high schools.
