Introduction: The aim of the present study was to investigate the effect of two nonlinear training models (Tactical Game Approach and Sport Education Model) on the level of tactical knowledge and performance of novice handball students.

Methods: This quasi-experimental study included pre-test, post-test and Transfer test design. Two schools were selected from areas with the same conditions using a multi-stage random clustering method. A total 46 students aged 13 to 15 years participated for 17 sessions. Data were collected through video recording, Game Performance assessment instrument and a written test. The data were analyzed using paired t-tests, mixed model ANOVA.

Results: The results indicated a significant increase in the level of tactical knowledge in the groups, but no significant difference was observed between the groups (P<0.05). Conversely, in evaluating performance under real-game conditions, the Tactical Game Approach group showed significant progress compared to the Sport Education Model group (SEM) (P<0.05). In the Transfer test, both groups showed a decline in performance; however, this decrease was more pronounced in the SEM group (P<0.05).

Conclusion: Tactical Game Approach can provide an appropriate response to the demands related to changes in game and training methods in handball through improving the motor skills and tactical knowledge of novice athletes. In addition, in the field of teacher education and professional development in physical education through the process of curriculum review and improvement of the physical education content in schools, attention to this teaching approach will have increasing importance.
