This study explored the effects of a parent–child learning programming together on elementary school students’ learning performance and attitudes and compared outcomes by gender. The study adopted a nonequivalent pretest–posttest design and involved two groups: an experimental group of 11 parent–student pairs and a control group of 10 students working alone. The participants learned Scratch programming in a 2-day computer science camp. Because the sample size was small, data were analyzed using a nonparametric method. No significant difference in learning attitudes between the groups was observed. However, the experimental group had more favorable learning outcomes than did the control group. In the experimental group, male students outperformed female students in the part of programming value. The parents and students in the experimental group reported positive attitudes toward the intervention.
