Although young people want to know more about sexuality, they do not feel they have received what they need to learn. In Chinese societies, scant research has solicited direct input from the youth to obtain their views on sexuality education (SE) deliverables. We found research gaps in the lack of Chinese preteens' input regarding SE timing, knowledge perception, learning readiness, and preteens' reasons for obtaining information about sexual health. In Hong Kong, a not-for-profit agency collected data from Chinese preadolescents who expressed opinions through a general survey. This agency surveyed students from 24 primary schools and provided anonymous secondary data for this team to analyze further. Among 4569 fifth- and sixth-grade students (average 11 years old), girls were more likely than boys to seek sex-related information from teachers, library books, and mothers. In contrast, boys were more likely than girls to obtain information from friends, pornographic comics, and the internet. Logistic regression analysis indicated that gender, age, instructional sources, openness to sexual health knowledge, and perceived and actual levels of knowledge predicted preteens' desire to receive SE earlier in grade school. Girls and older students were significantly more likely to report their preference to receive SE in an earlier grade. We recommend that preteens and their parents be encouraged to collaborate with teachers to participate in school-based SE programming. Copyright © 2023 Springer Nature.

In addition to enabling students to gain knowledge, education aims to make them competent, confident, and enthusiastic learners. Using TIMSS 2019 data from eighth graders in mathematics classrooms in Hong Kong (N = 1146) and England (N = 1981), this study explored the relevance of classroom management and instructional clarity to students' mathematics self-concept and value, academic emotions (i.e., enjoyment and boredom) and mathematics achievement by using a latent multi-group SEM analysis. The findings corroborated the controlvalue theory and indicated that classroom management was not always beneficial to the increase of students' enjoyment and achievement in Hong Kong, but the favorable effects of classroom management on academic emotions and achievement were observed in England. Additionally, instructional clarity has been demonstrated to improve students' enjoyment and achievement in mathematics while reducing boredom in both groups, with the advantage being greater in Hong Kong classrooms. The limitations and implications are then discussed. Copyright © 2022 Elsevier.
