This study examined the views of secondary school students on sexuality and sexual health education in Hong Kong, China. A total of 818 secondary school students (mean age = 15.3 years, SD = 1.6) participated in this study by completing a questionnaire consisted of items on sociodemographic characteristics, sexual attitudes, and other measuring scales. Students were slightly permissive in sexual attitudes and supported sexual health education. However, students who were male, highly liberal in sexual attitudes, and low in religiosity and spirituality were less supportive. Educators may need to address these deterring factors of sexual health education before teaching specific sexual health topics.

The erosion of filial piety and prosocial behavior during China’s economic reforms signals a concerning decline in moral development within society. Insufficient teaching resources in rural areas hinder left-behind children from receiving adequate moral education. The SMART moral education program employs an activity-based approach to address this gap, specifically targeting rural left-behind children. The SMART moral education emphasizes sharing behavior and interpersonal relationships. This study involved the primary three students from two elementary schools in Hunan Province, utilizing a control group ( n = 78) and an experimental group ( n = 58) to assess the effectiveness of SMART moral education in fostering prosocial attitudes and reciprocal filial piety. Results from factorial ANOVA indicated that SMART moral education significantly enhanced altruistic attitudes and reciprocal filial beliefs among participants. This study offers preliminary evidence supporting SMART moral education as an effective strategy for promoting moral development among left-behind students.
