This research provides the instructional exploration of analytic geometry pattern based on van Hiele thinking pattern, and the potential of GeoGebra effect on experimental group along with its nested group (high and low achievers) in comparison with control group in analytic geometry. To investigate the significant effect of GeoGebra, the two match groups were constructed on their previous grade-11 mathematics records with almost equal statistical background and with the same compatibility in the biological age. Further, six-week experiments of 22 lessons were prepared and two teaching methods (tradition vs DGS aided instructions) were tested. Three hypotheses were carried out i.e. Treatment does not significantly affect, the two groups in mathematical achievement mean scores and, the higher and low achievers of the two groups in mathematical achievement mean scores. To measure the treatment effect, t-test was used by SPSS. Analyses of the research revealed that experimental group performed well, while; GeoGebra was influential in favor of low achievers in comparison to control low achievers.
Although each and every aspect of individual is affected by the family system variables, but the most important one is their moral development. Moral development is the ability to differentiate between the good and the bad behaviors. This study explores the effect of family systems, especially, nuclear and joint families on the moral development of both boys and girls elementary level students. All 222944 elementary level students of Khyber Pakhtunkhwa, Pakistan constituted the population of the study. A total of 384 elementary students randomly selected, (226 boys and 158 girls) were taken as the sample of the study. Kohlberg’s Moral Judgment Interview Form A was used for the collection of data. The collected data were analyzed through frequency, percentage and analysis of variance (ANOVA). The findings of the study depicted that gender had significant influence on the moral values of elementary level students. Furthermore, girls belonging to the joint families were found morally more advanced than boys of joint families.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
