The present study was carried out to examine the impact of guided exploratory teaching method on achievement emotions of male elementary school sixth graders. This quasi-experimental research had a pretest-posttest control group design. The statistical population of the study comprised all male elementary school students in Meybod in 2020-21 school year from among whom 30 pupils were selected via random cluster sampling method and randomly assigned to two groups of experimental (N=15) and control (N=15). The guided exploratory teaching method was utilized for the experimental group and the conventional teaching method was used for the control group. The research instrument included Achievement Emotions Questionnaire (elementary school students form). To analyze data, multivariate analysis of covariance was used. The results showed that guided exploratory teaching method had a significant effect on the enjoyment of attending math classes. Also, guided exploratory teaching method significantly increased the pleasure of doing math assignments and significantly reduced the anxiety of doing math homework. In addition, guided exploratory teaching method increased the pleasure of taking math exams and reduced math exams anxiety. Accordingly, guided exploratory teaching method can be used as a useful intervention to organize students’ achievement emotions.
