Based on the cognitive-motivational model of achievement and emotions, this study is to explore the effects of students’ academic emotion and learning engagement on academic achievement in junior high schools, and to review its fitness for testing the model constructed. The participants were 640 junior high school students. The final results showed that: (1) There is adequate fitness between the observed data and the theoretical model; (2) The positive and negative academic emotions had direct effects on students’ learning engagement; (3) The positive and negative academic emotions also had direct effects on students’ academic achievement; and (4) The learning engagement had direct effects on students’ academic achievement, too. The possible pedagogy implications for intervention and future research were also discussed. |
