To improve the badminton skills learning of students, this study proposed the portfolio-based WISER model, which combines tablets for instantaneous recording and Facebook for e-portfolios. The 97 learners in the experimental group (EG) were taught with tablets and Facebook, and the 102 learners in the control group (CG) were taught with traditional teaching methods. The paired sample t test and ANCOVA were used for statistical analysis. The posttests of smashing and footwork in the EG and CG were both significantly higher than those on the pretests. The posttest scores for smashing were significantly higher in the EG than those in the CG. For pretest scores were higher than 7.66 or lower than 5.09, the posttest footwork scores were significantly higher in the EG than in the CG. The proposed portfolio-based WISER model can help students reinforce their understanding of badminton skills and improve their skill learning.
