Abstract: In this paper we define and study some allied regular spaces using gsp-open sets and gsp-closed sets , namely (sp,gsp)-regular spaces, gsp-regular spaces,(gsp,gs) -regular spaces, weakly g*regular spaces, (gsp,sp)-regular spaces,(p,gsp)-regular spaces and strongly gsp-regular spaces. also, we defined some basic characterization of above mentioned regular spaces. Mathematics Subject Classification (2010) : 54A05,54B05,54C08 ,54D10.

Keywords: semipreopen sets, gsp-closed sets .g*-closed sets preopen sets ,gs-closed sets, gsp-irresoluteness, and strongly g*-continuums functions.

Abstract: The effect of pedagogy on student interest is very important in contemporary educational research. Factor Analysis of Teachers' Teaching Methodswas carried and how these extracted factors affect students' interest in Mathematics was investigated. Data was collected from ten (10) senior high schools in Ashanti region of Ghana with one thousand two hundred and sixty-three (1263) students' randomly selected to participates in the study. The ten factors that influence teaching methods and strategies were reduced to three principal components, and these were further used for regression analysis as predictors of student Mathematics interest. The study concluded that, pedagogical factor oriented model can predict significantly (p-value<0.001) 12% of variance in students' interest....
