Abstract
Objective: To investigate the factors that influence undergraduate Sudanese nursing students' academic achievement.
Methods: An online survey was conducted among 235 Sudanese nursing students using several scales and questionnaires to assess cognitive, affective, and psychomotor domains of academic achievement, self-regulated learning (S.R.L.), engagement, academic stress, and grade point average (GPA). A hierarchical multiple linear regression model was used to identify the predictors of academic achievement.
Results: Academic achievement was significantly correlated with SRL (r = 0.588, p<0.001), engagement in distance learning (r = 0.476, p < 0.001), academic stress (r = 0.355, p<0.001), and GPA (r = 0.162, p=0.02). No significant correlation was found between academic achievement level and demographic or learning experience variables, participating in a learning support program, voluntary study meetings, and receiving learning counseling. Engagement in distance learning and SRL were identified as significant predictors of academic achievement, with adjusted R2 values of 0.216 and 0.377, respectively.
Conclusion: The study highlights the importance of engagement in distance learning and SRL among Sudanese nursing students in the context of distance learning. The nursing institutions need to develop effective strategies to enhance students' engagement and SRL skills to promote academic success in distil learning.
