It was compiled by the Indian sage Vatsyayana sometime between the second and fourth centuries CE.His work was based on earlier Kamashastras or Rules of Love going back to at least the seventh century BCE, and is a compendium of the social norms and love-customs of patriarchal Northern India around the time he lived.
These results suggest different mechanisms for the effects of mixed-gender schools on boys’ and girls’ academic performance.
The preceding cohort, while not exposed to mixed-gender peers at the classroom level, were exposed to a school-level co-ed environment (and any school-wide changes due to the switch) for the last two of their three years of high school.
To the extent that school-level exposure to the newly-co-ed environment affect these two cohorts similarly, the difference in attainment between the two cohorts (and the corresponding difference in non-switching schools) allows us to answer our final question: We make use of the multi-grade nature of South Korean high schools, and the cohort-level conversion of pupil gender type.
This allows us to address our first question: While causal, this shows the combination of the direct effect (driven by pupil gender composition) and the school effect (driven by other differences between single-sex and co-ed schools).
We find robust evidence that pupils in single-sex schools outperform their counterparts in co-ed schools, by 5–10% of a standard deviation for boys and 4–7% for girls, with similar estimates across subjects (which include Korean, English, and maths).
For girls, however, it is classroom-level exposure to mixed-gender (versus same-sex) peers that explains the disadvantage from co-ed schooling. Dustmann, C, H Ku and D W Kwak (2017), “Why are single-sex schools successful?
While teenage boys may be more likely to be distracted than girls by a mixed-gender school environment (Coleman 1961, Hill 2015), girls may suffer more because of, for instance, an increase in disruptive behaviour (as discussed by Figlio 2007), or a diversion of the teacher’s attention to weaker students (as suggested by Lavy et al.
In recent years, single-sex education has attracted much policy interest as a potential tool for promoting pupils’ academic achievements and closing various types of gender gap.
Proponents of single-sex education argue that the single-sex environment is beneficial to academic achievements for reasons such as students avoiding the attraction of the opposite sex, and being less likely to suffer from gender stereotypes.
Preserved by a series of fragmentary papyruses which attest its popularity, it served as a source of inspiration for Ovid's Ars Amatoria, written around 3 BC, which is partially a sex manual, and partially a burlesque on the art of love.
The Kama Sutra of Vatsyayana, believed to have been written in the 1st to 6th centuries, has a notorious reputation as a sex manual, although only a small part of its text is devoted to sex.
We find that class-level exposure to same-sex (versus mixed-gender) peers has a significant positive effect on the attainment of girls.
