Introduction. Homework is a core context for self-regulated learning (SRL), motivational regulation, and parent-child socialization. Cross-cultural work shows Chinese students devote more time and report fewer negative attitudes than Western peers. Yet developmental patterns, within-school variability, and the coupling of school-assigned and self-arranged study in Hong Kong remain under-specified.
Purpose. We examined (a) time distributions for school-assigned homework/revision and non-school (parent/self-arranged) study across stages; (b) between- versus within-school variability; and (c) coupling among study domains/activities and links with achievement, socioeconomic status (SES) and other attitude/motivational constructs to identify intervention targets grounded in educational psychology.
Method. Multiwave, representative samples totaling ~30,000 Hong Kong students in Grades 3-9 completed attitude/motivation questionnaires adapted from PISA. Parents reported daily time on school-assigned and non-school study and activity type (Chinese, English, Mathematics, interest classes, sports, arts). Analyses used weighted descriptives, variance partitioning, and stage-stratified correlations; earlier waves triangulated a 2017 module with more detailed homework items.
Results. Results showed ≤2 hours/day of school-assigned study was reported by 83%-86% of students; 48%-59% had ≤1 hour. For non-school study, 69%-74% reported <30 minutes/day and 26%-31% reported ≥1 hour/day. Between-school differences in study time were small, whereas within-school heterogeneity was large. At least 70% of study time focused on Chinese, English, and Mathematics; English time decreased and Mathematics increased from Grade 3 to Grade 9. Students with more school-assigned homework also did more parent/tutor-assigned work (r≈.50-.60). Heavy study time in primary occurred across SES and achievement; by Secondary 3 it aligned more with higher achievement.
Conclusions. From middle childhood to adolescence, learning time shows increasing coherence consistent with SRL consolidation. Psychologically informed supports should target within-school outliers, calibrate parental expectations, and differentiate homework to sustain motivation and mitigate SES-linked risks, rather than impose school-level quotas.
