Based on the control-value theory, this study qualitatively investigated the relationship between control-value appraisals, achievement emotions, and English-as-a-foreign-language performance, and explored other antecedents of achievement emotions in addition to control-value appraisals. Data were collected from six Chinese high school students through two semi-structured interviews and one focus group discussion. With thematic analysis, data were analyzed under the framework of the CVT using NVivo 11.0. Results indicate that high perceived control, high perceived extrinsic, and intrinsic values were interactively associated with enjoyment, (...) pride, and hope. Low perceived control, high perceived extrinsic value, and low perceived intrinsic value were interactively associated with fewer positive achievement emotions and more negative achievement emotions like fear. High perceived control, high perceived extrinsic value, and low perceived intrinsic value were interactively associated with fewer positive achievement emotions, and more negative achievement emotions like anguish. Besides, positive achievement emotions were positively associated with EFL performance, while negative achievement emotions were negatively associated with EFL performance. Moreover, factors inside the classroom, factors outside the classroom, and personal factors were found to be the antecedents of achievement emotions in EFL learning. (shrink)
