The results revealed that (1) family background, technical learning engagement, and self-efficacy were significantly and positively correlated (p<0.01), with girls' technical learning engagement (M female=5.81, M male=5.19, p<0.01) and self-efficacy (M female=3.34, M male=2.66, p<0.01) significantly higher than boys'; (2) technical learning engagement partially mediated the effect of family background on self-efficacy (ab=0.10, boot SE=0.02,95% CI=[0.07, 0.14]); (3) the first half of technical learning engagement's mediating role was moderated by gender (B=0.05, p<0.01), with a more significant influence of family background on boys' (B=0.24, p<0.001, 95% CI=[0.22, 0.26]) technical learning engagement than girls' (B=0.19, p<0.001, 95% CI=[0.17, 0.21]); (4) the second half of technical learning engagement's mediating role was moderated by training years (B=-0.21, p <0.001), with a more significant influence of technical learning engagement on the self-efficacy of adolescents with fewer training years (B=0.54, p<0.001, 95% CI=[0.39, 0.68]). The positive effect of technical learning engagement on self-efficacy gradually diminished with increasing training years, and the moderating effect of training years disappeared when the training years reached 8.94 years.
